Title: Agc voltage correction circuit
Inventor: NISHIWAKI MASAHARU
IPC: H04N5/52
Filed: 1977-12-02
Abstract: PURPOSE: To stabilize the meter circuit and the like as well as to secure the assured AGC operation by compounding the output of the AGC detector circuit and the voltage at the transistor's emitter point of the RF part with a proper mixture ratio and then delivering the DC voltage featuring the desired function relation between the reception fields.  
     CONSTITUTION: When the reception field is intensified, the voltage of AGC amplifier 14 is lowered. And the collector current of transistor Tr4 is reduced through loop L 2 , and AGC is spplied to Tr4. Thus, the voltage is increased at the emitter point of Tr4 and then supplied to adder 17 via buffer amplifier 15 and DC amplifier 16. On the other hand, the AGC voltage of AGC detector circuit 13 is  applied to other input of adder 17 through amplifier 22. As a result, the voltage increasing with increase of the reception field intensity is delivered at the emitter point of Tr4. Then the output of circuit 13 and the voltage at point (a) are compounded with a proper mixture ratio, and thus the DC voltage featuring the desired function relation is delivered between the reception fields.

Filed: 1980-10-16
Abstract: PURPOSE:To exercise hunting-free stable control by obtaining a true value for a target water level, by providing a detector, which measures the extent of opening of gate facilities, to an automatic control system which obtains the target-value extent of opening by controlling a gate, a valve, etc. CONSTITUTION:A target water level set by a setter 1 and an actual water level by detector 5 are compared mutually to obtain the difference between the both, and at the same time, an opening-closure signal is obtained which corresponds to the fluctuations of the extent of opening inputted from a detector 6 to gate facilities 3. Therefore, a controller 2 is unable to know the extent of opening of the gate facillities 3 directly for the target water level, but the extent of opening corresponding to the target value exists between a maximum and a minimum value in a period right before the point in time, so it is able to approximate the actual water level to the target value by detecting the target-value extent of opening, thereby reducing waterlevel fluctuations due to hunting asymptotically. In the figure, 4 is controlled object (e.g. water level) controlled by the gate facillities.

Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To improve communication performance by making the cutoff frequency of an HPE and the cutoff frequency of an LPF lower than the cutoff frequency of a stabilizing circuit. SOLUTION: The cutoff frequency of the HPF 2 and the cutoff frequency of the LPF 5 are set much lower than the cutoff frequency of a voltage regulator 6.

With characteristics like this, the impedance observed from the transmitting and receiving means 3 eventually has the impedance value of a line load passed through the HPF 2, so that the phenomenon where a transmit signal is absorbed by a power receiving circuit as a load is not generated in a frequency band in which the output of the transmitting and receiving means 3 decreases.

IPC: B42D15/10
Filed: 1990-06-06
Abstract: PURPOSE:To allow the IC card system to correspond to a communication system such as a broadcast system, as well by providing a transmission line of a data clock between a reader/writer and an IC card so that a data communication by a clock synchronizing system can be executed, and setting the data clock to a unidirectional transmission extending from the reader/writer side to the IC card. CONSTITUTION:A transmission line 19 of a data clock is provided between a reader/ writer 17 and an IC card 18 so that a data communication by a clock synchronizing system can be executed, and also, the data clock is set to a unidirectional transmission extending from the reader/writer 17 to the IC card 18. Accordingly, a data transmission rate between the reader/writer 17 and the IC card 18 is enhanced remarkably. Also, since the data clock is sent only to the IC card 18 side from the reader/writer 17 side, the data transmission to the IC card 18 from the reader/writer 17 and the data transmission to the reader/writer 17 from the IC card 18 are controlled by the reader/ writer 17 side. In such a way, when the IC card system is applied to a broadcast communication system, the IC card 18 can be controlled in one direction from the broadcast communication system side, and it conforms to the broadcast communication system.
