摘要： PURPOSE:To improve the convenience of the telephone set by the user by automating dialing when a time and a content of telephone dialing are decided in advance in the case of dialing. CONSTITUTION:Input data by a ten-key of a numeral entry device 8 are stored in a time storage device 2 as time data. When a dial destination setting button 12 is depressed, a dialing destination telephone number entry is awaited, When a voice signal is inputted from a receiver 10, voice data are stored in a voice storage device 6. When a set button 14 is finally depressed, a controller 4 enters a dialing wait state and a timer device 1 starts comparison between time data from a clock 3 with data of the storage device 2. When both data are coincident, that is, the setting time comes, the timer 1 outputs a dial start signal commanding the start of dialing to the controller 4. Upon the receipt of the dial start signal, the controller 4 calls a destination telephone number from the destination telephone number storage device 5 and makes dialing from a terminal 7.

摘要： PURPOSE:To easily retrieve timer setting parts independent of the number of reservations and to select execution/nonexecution by wholly completing the releaseing of reservations or timer recording after executing plural timer recordings. CONSTITUTION:When a user set a time recording device 106, a variable (n) in a memory 104 is reset '0'. Next, a release from the timer recording is monitored and when the release is executed before timer recording, an operation is completed. When the release is not executed, if the content of timer setting remains, a present time and the starting time of the device 106 are compared, then in the case of coincidence, the operation pf recording is started, and a program serching signal (index) is recorded and '1' is added to the variable (n) of the memory 104. Thereafter, the release from the timer recording is monitored, and the present time and a completion time are compared, then in the case of coincidence, the operation of a recording and reproducing device 107 is stopped.

摘要： PROBLEM TO BE SOLVED: To stably detect wobble signal necessary for controlling a spindle motor from a guide groove meandering at a specific frequency and being also partly intermittent, to settle the spindle motor at a high speed and stably by using the signal, and further, to control the spindle motor in a state without obtaining the wobble signal. SOLUTION: A spindle motor 30 is controlled by detecting a wobbling signal synchronized with a guide groove 12 by a PLL circuit 24 ceasing its operation synchronizing with a reproduced ID, frequency-dividing the wobble signal into ID frequency or more, and using the frequency-divided wobble signal. When the wobble signal is not detected, the spindle motor 30 is controlled based on FG signal.

摘要： PROBLEM TO BE SOLVED: To prevent electric discharge from being centralized and avoid a momentary large current by utilizing variation of discharge start voltages and delays in discharge of each cell by making gentle a sustained pulse for a light- emitting display for the rising time. SOLUTION: There is a possibility that electric discharge by a 1st sustained pulse 58 may be weak and wall charges may not sufficiently be accumulated by impression of a short time pulse for the reasons that charge amounts are insufficiently accumulated on a dielectric substance in the neighborhood of an electrode X for a write period 41-48-B and on a dielectric substance in the neighborhood of an electrode Y, etc. Therefore, the delay in discharge is coped with by lengthening a period for applying voltage, and also much charges are collected on the dielectric substance in the neighborhood of the X-electrode, and on the dielectric substance in the neighborhood of the Y-electrode. In such a manner, when a 1st pulse in an X-sustained pulse 57 is applied to the X- electrode next, electric discharge is generated with a sufficient discharge intensity and little delay to the pulse impression. Namely, the rising of the voltage waveforms of the sustained pulses 57, 59 to be impressed should be made gentle.

摘要： PURPOSE:To reduce the synchronization locking time without use of a phase difference setting circuit and a phase comparator circuit by adding a half of the phase difference relating to a period of an internal clock to a phase of an internal clock. CONSTITUTION:An external synchronizing signal inputted from an input terminal 1 is fed to a phase difference detection circuit 2, the phase difference detection circuit 2 detects a phase difference between the inputted signal and an internal clock outputted from a clock generating circuit 5 and the result is fed to a frequency divider circuit 3. The phase difference is halved and fed to an adder circuit 4, in which the phase of the internal clock and the halved phase difference are added. Then the added internal block is fed back to a frequency divider ratio setting circuit 6. The frequency divider ratio setting circuit 6 changes the frequency divider ratio by the fed-back internal clock to change the period of the internal clock generated in the clock generating circuit 5. Moreover, the clock generating circuit 5 changes the period of the internal clock by changing the frequency divider ratio of the output of the crystal oscillator.
