摘要： PURPOSE:To improve burglar preventive effect on a vehicle by providing both a means sotring password numbers and a means judging whether or not an inputted password number is in a good agreement, and thereby using the actuating section of an on-vehicle acoustic device which can be remotely controlled as a password number inputting means. CONSTITUTION:When an actuating switch 4 is actuated in order to actuate an acoustic device 8 and a locking device 9 in a remote actuating device 1, let a transmitting code corresponding with the switch 4 be generated by a transmitting section 2 so as to let an infra-red photo-diode 3 be radiated. And let infra-red ray signals generated by the diode 3 be received by each pin photo- diode 5 and 10 of the acoustic device 8 and the locking device 9. And in the acoustic device 8 side, received signals are decoded by a receiving section 6 so as to let necessary control be assumed to an acoustic equipment 7. And in the locking device 9 side, received signals are amplified by an amplifier 11 so as to be decoded by a decoder section 12 thereafter so that they are compared with the password number stored in a non-volatile memory 14. And when both of them are in a good agreement, locking is released with a locking drive section 15 actuated.

摘要： PURPOSE:To keep the pleasant cabin environment by detecting it that a vehicle enters a tunnel and automatically switching a radio receiver into other audio equipment. CONSTITUTION:A control section 7 is provided with a lighting switch signal input 10 and a broadcast station detection signal input 8 representing whether or not a radio wave from a broadcast station is received and always monitors the two signals. Then the control section 7 checks the two signals to check whether or not the vehicle enters the tunnel, that is, to check whether or not the broadcast station detection signal is absent. If reception is disabled while entering the tunnel during the listening to a radio receiver, a control signal 9 is outputted and the audio equipment is switched into a cassette tape deck halt tentatively.

摘要： PURPOSE:To apply with no conflict all setting systems such as a time setting system using a ten-key, the system carrying an hour or a minute digit and at the same time to simlify circuit constitution by setting a prescribed time as an ON and an OFF time points for timer operation when a power supply is powered-on and deciding the relation between the ON and the OFF time points to control the timer operation. CONSTITUTION:Data is previously set to an initial time setting memory 10. A control circuit 1 reads the data of the memory 10 at the first powering-on of an AC power supply and at the same time writes the data as it is to the ON and the OFF time point setting memories 3 and 4 respectively. A comparator 9 secures an exclusive OR for each bit between the memories 3 and 4 and then connects these AND outputs to the circuit 1. The circuit 1 performs no control as long as the memory 3 is coincident with the memory 4. Therefore a display converting circuit, etc. can be excluded. Furthermore a timer never works before a timer time point is set.
摘要翻译：目的：无冲突地应用所有设定系统，例如使用十键的时间设定系统，系统携带小时或分钟的数字，同时通过将规定的时间设定为ON和 OFF电源供电时定时器运行的时间点，并决定ON和OFF时间点之间的关系，以控制定时器运行。构成：先前将数据设置为初始时间设定存储器10.控制电路1在交流电源的第一次通电时读取存储器10的数据，同时将数据原样写入ON 和OFF时间点设定存储器3和4。比较器9确保存储器3和4之间的每一位的异或，然后将这些AND输出连接到电路1.只要存储器3与存储器4重合，电路1就不执行控制。因此，显示转换电路等可以排除。此外，在定时器时间点设置之前，定时器不工作。

摘要： PURPOSE:To obtain a multi-band radio receiver capable of efficiently switching bands only by one band changing switch. CONSTITUTION:Prescribed channel selection control is executed by a microcontroller 1 and receiving frequency, a preset number, etc., are sent and displayed to/on a display part 2. A band changing switch 4 in a switch part 3 is a band changing switch for channel selection and includes a preset button also. When the switch 4 is depressed, the microcontroller 1 judges whether band switching is to be executed or not, and in the case of switching a receiving frequency band, outputs an AM band switching signal 101 or an FM band switching signal 102 to execute the switching operation of a peripheral circuit and broadcasting reception for the selected channel.

摘要： PURPOSE:To facilitate the confirmation of timer time by displaying the timer time for a constant time when a stand-by switch is turned on. CONSTITUTION:A control circuit 1 performs the clocking operation of a timepiece on the basis of the reference oscillation frequency of a crystal oscillator 4. The clocked time drives a display device 3 by a display circuit 2. An operation switch 5 is used to adjust the current time and also turn on and off a stand-by mode. The timer-ON time set by this switch is stored in a memory 6 for timer-ON time storage. The circuit 1 uses a microcomputer frequently and when the stand-by switch is turned on to enter a stand-by mode, the timer time is displayed for a certain time. Thus, the timer time is displayed every time the stand-by switch is turned on, so an error in the setting of the timer time is easily found.

摘要： PURPOSE:To provide a programmable timer which enables the ON or OFF turning by the last source determined finally after selections by providing a last source memory connected to a control circuit and a memory for control sources. CONSTITUTION:When a control circuit 1 rewrites a timer ON time memory 3 by the operation of a keyboard 8, the control circuit 1 reads out and writes the contents of a last source memory 11 into a source controlling memory 10. At this point, the source controlling memory 10 gives the same as the last source memory 11. The last source memory 11 has a source currently selected written thereinto. This memory is equivalent to a tuner, a deck, a player and the like in an audio stereo set and the last source to a band, a frequency and the like currently received in a tuner. This enables the rewriting of the contents of a memory for controlling sources simply by setting the time for turning ON or OFF of a programmable timer with the operation of a keyboard thereby ensuring the turning ON of the timer with the last source when turning ON it.
摘要翻译：目的：提供一个可编程定时器，通过提供连接到控制电路的最后一个源存储器和用于控制源的存储器，可以在选择后最后确定的最后一个源的ON或OFF转换。构成：当控制电路1通过键盘8的操作重写定时器ON时间存储器3时，控制电路1将最后的源存储器11的内容读出并写入源控制存储器10.此时，源控制存储器10给出与最后的源存储器11相同的位置。最后的源存储器11具有当前被选择写入的源。该存储器相当于音频立体声组中的调谐器，卡座，播放器等，以及当前在调谐器中接收到的频带，频率等的最后的源。这就可以简单地通过用键盘的操作设定可编程定时器的ON或OFF的时间来重写用于控制源的存储器的内容，从而确保在打开时用最后的源打开定时器。

摘要： PURPOSE:To attain automatic storage without increasing number of operation switches by using a memory write switch and an automatic channel selection switch so as to activate an automatic storage function. CONSTITUTION:When a control circuit 4 starts its operation, it checks for the state of an operation switch 5. When the operated switch is the memory write switch in this case, a memory write enable state is continued for a prescribed time. When the switch operated during the time is the automatic channel selection switch, automatic storage operation is executed. Frequency sweep is executed automatically in the automatic storage operation and a frequency with a station detection signal input 7 is written in a RAM 6. That is, when the memory write switch is depressed and the automatic channel selection switch is depressed during the write enable state, the automatic storage is applied. Thus, the automatic storage operation is attained without increasing the number of operation switches.

摘要： PURPOSE: To adjust the direction of an FM receiving antenna without viewing a meter by changing a DC voltage output which corresponds to the intensity of a received electric field into a sound of audio frequency varying with a voltage by a voltage-controlled variable frequency oscillator.
CONSTITUTION: An FM received radio wave picked up by an antenna 1 is amplified and frequency-converted at a front end 2 and then amplified and detected by an intermediate frequency amplifying and detecting part 3; and the DC voltage output corresponding to the intensity of the received electric field is inputted to the voltage-controlled variable frequency oscillator 7 and the detection output is demodulated on stereophonic basis by an FM multiplexer 4. Then, a broadcast received tone is outputted from a speaker 6 through an amplifier 5 at the side of a contact A of a changeover switch 8. When the switch 8 is placed at the side of a contact B, on the other hand, an audible tone corresponding to the intensity of the received electric field is outputted from the speaker 6 through an oscillator 7.

摘要： PURPOSE:To constitute the title system so that whether its acoustic device has been installed or not can be discriminated by only looking at from the outside of a car and to prevent a theft in advance by providing an operating part which can be brought to remote control and taking out only its operating part when a user leaves a car, or keeping it in a place which cannot be seen from the outside. CONSTITUTION:A key which has been operated by a key matrix part 3 is encoded by a transmitting part 1, and an infrared-ray light emission diode 2 is brought to a light emission. On the other hand, on the receiving side of data, a signal which has been received by a pin-photodiode 4 is amplified by a pre-amplifier 5, which key has been operated is decoded by a decoder part 6 consisting of a microcomputer, and a main body part 7 is controlled. For instance, when a power source ON/OFF key has been operated, the main body part 7 sets the power source to ON or OFF. In such a way, by making the operating part containing the key matrix part 3 small in size and light in weight, it will suffice that only a light receiving part is installed in a place which can be seen, it is unnecessary to detach and attach the whole apparatus as a theft preventing device, and theft can be surely prevented.

摘要： PURPOSE:To make it possible to set OFF-time to arbitrary time if a manipulation switch is manipulated and to set preset time after predetermined time is elapsed unless manipulated, by providing a control means for automatically setting the cancel-time after predetermined time is elapsed to second memory when only operation time is set to first memory. CONSTITUTION:Memory impossible in usual rewriting such as ROM is used in add data memory 4 and data is preset thereto. When only ON-time is set by manipulating a keyboard 9, a control circuit 10 writes ON-time data in timer ON-time memory 3 while mutually adds this data and the data of the add data memory 4 and performs control so as to write the added data in timer OFF-time memory 5. In addition, when the OFF-time is set by manipulating the keyboard 9, the control circuit 1 cancels the added data and sets the set time to the timer OFF-time memory 5.
