摘要： PURPOSE: To provide an adapter device between an antenna plug and the rest of a radio telephone set. CONSTITUTION: A radio telephone set 15 is provided with a housing 14 by which an adapter member 10 of the antenna plug is received on a rest 13. The adapter member 10 is provided with an electromechanical connection end part 11 cooperating with the antenna plug and at least an electric connection means 12 cooperating with the rest 13. The rest 13 is electrically brought into contact with the connection means 12 by merely inserting the adapter member 10 into the housing 14 in the axial direction, and the adapter member is held in the housing 14 with a manually operated holding means 23 between them so that it electrically connects the antenna plug and the rest 13. Thus, an antenna especially on the market can be connected to a specific radio telephone set, and the frequency in attachment and detachment of the antenna can be increased.

摘要： PURPOSE: To obtain the inexpensive automatic gain control method that compares each sample with four limits, that is, maximum and minimum limits and limits in opposite sign to the maximum and minimum limits respectively. CONSTITUTION: A limit detector 4 evaluates an absolute value of an amplitude of each sample by comparing each sample with a maximum limit used to detect a too high gain of an amplifier 2 and with a minimum limit used to detect a too low gain of the amplifier 2. For example, the detector 4 compares each sample amplified by the amplifier 2 at its gain with a maximum limit that is placed at a 6dB below a saturation level of a base band signal of the receiver and used to detect a too high gain of the amplifier 2 and with a minimum limit that is placed at a 10dB below the saturation level of the base band signal of the receiver and used to detect a too low gain of the amplifier 2. A control logic device 3 interprets information from the detector 4 and adjusts a gain G of the amplifier 2 while ensuring the stability of a loop according to a prescribed algorithm. In the case that the absolute value of each sample exceeds the maximum limit, the gain G is decreased by 3dB, in the case that the absolute values of two consecutive samples are smaller than the minimum limit, the gain G is increased by 3dB, and in other cases, the gain G is kept without any modification.

CONSTITUTION: The apparatus comprises a first connecting member 1 and a second connecting member 2 having a first member and a second member. When assembled, the two connecting members 1, 2 are first engaged with each other along an engaging shaft. A fixing element 13 of the first connecting member 1 is inserted into a receiving element 23 of the second member 2 by the engagement. The apparatus further comprises a cylindrical sliding element i.e., a tube 3 having a returning spring 12 separating the first connecting member 1 from the second connecting member 2, and playing a pressurizing function for holding the inserted fixing element 13 in the receiving element 23. The tube 3 has a built-in spring 4 for connecting and locking the fixing element 13 and the receiving element 23 in a secured way, as well as a rod 35 for cooperating with the spring 4 to unlock by exerting and releasing pressurizing on the rod 35. The fixing and receiving elements 13, 23 have complimentary shapes.

摘要： PURPOSE: To compromise power consumption with control search by providing an synchronous mechanism which responds to a control signal and ascertains whether it is connectable or not and a timing mechanism which responds to a wait period and generates a control signal. CONSTITUTION: A synchronous mechanism is controlled by a timing mechanism that uses a control circuit 4. During an initial period, the timing mechanism controls the synchronous mechanism with one control signal. If synchronization is not acquired after the initial period, the timing mechanism stops the control over the synchronous mechanism during a 1st wait period. And it starts a 2nd wait period, newly generates a control signal and performs periodical control over the synchronous mechanism. It makes the wait terminal long to make the interval of a starting period of the synchronous mechanism wide. As a result, although energy consumption is reduced, the synchronization of a terminal is delayed. Here, the timing mechanism is provided with a means that decides a wait period in accordance with a capacity indicator. This makes it possible to compromise between the reduction of power consumption and terminal use.

摘要： PURPOSE: To improve transmission and reception conditions and to make it possible to use the transceiver with the right or left hand by making the main radiation direction of an antenna substantially perpendicular when the transceiver is held in the hand and put close to the head of a user. CONSTITUTION: When a casing 1 equipped with a transmission part 2 and a reception part 3 is held in the hand and arranged at an in-use position, a specific angle α is generated between the length direction of the casing 1 and the vertical. This angle is substantially constant irrelevantly to the user and a slender antenna 3 is provided which slants at an angle α to the length of the casing 1. Therefore, when the casing 1 is held at a normal use position, the antenna 4 becomes vertical to have an optimum radiation pattern, and the main radiation direction of the antenna 4 becomes substantially vertical. This transceiver has a lock position 6 where the antenna 4 is directed vertically when the antenna 4 is coupled with a turning support shaft and the casing 1 is held in, for example, the right hand.

摘要： PURPOSE: To provide a device for correcting frequency deviation caused by a Doppler effect suitably for a transmission system having a receiver constituted so as to correct the limited fluctuation of carrier frequency. CONSTITUTION: The device for correcting the frequency deviation caused by the Doppler effect is applied to the transmission system for transmitting signals between transmitter S and receiver R relatively moving in a transmission lobe. Frequency deviation ▵F as difference between a frequency fr of transmitted signal measured by the receiver R and a frequency fe of transmitted signal measured by the transmitter S is shown as the sum of central frequency fc showing the feature of transmission lobe and a position frequency fp as the function of the position of receiver R in the transmission lobe. This device is provided with a means for tuning the receiver R having a tuning frequency fa so that the tuning frequency fa can be equal with the sum of transmission frequency fe and central frequency fc.
