Title: Simple talking circuit
Inventor: YAMANOUCHI MICHIO
IPC: H04M1/60
Filed: 1988-03-25
Abstract: PURPOSE:To decrease the cost of a telephone set by controlling the output of a receiving amplifier by one part of a transmitting amplifier and making an input signal level to a receiving element variable. CONSTITUTION:The title circuit is equipped with input terminals L1 and L2 of the taking circuit of the telephone set, a transmitting element T, receiving element R, a transmitting amplifier TAMP, a receiving amplifier RAMP and a control circuit ATT. When hearing the voice of an opposite person while the telephone set is engaged, a RAMP operates by the loop of L1-RAMP-TAMP- L2 and the voice of the opposite person is heard by the loop of RAMP-ATT-R. When speaking, the TAMP operates by the loop of L2-TAMP-RAMP-L1, the voice of the speaker is sent between L1-L2, at the same time, the ATT is controlled by one part of the output of the TAMP and the input signal level of an R is made smaller (sidetone attenuation effect). Thus, not only the call but also the lowering of the cost can be realized in a convertional general subscriber's telephone set.

Title: Phase synchronization pulse signal generator circuit
Inventor: OBA YUJI
IPC: H03L1/02
Filed: 1993-03-30
Abstract: PURPOSE:To generate a corrected reference subcarrier and to generate a subcarrier phase locked to the corrected reference subcarrier even when a characteristic change takes place due to a temperature change in a band pass filter(BPF) extracting the reference subcarrier from a video signal VIDEO. CONSTITUTION:A BPF 21A extracts an original external reference subcarrier EXT-SCO included in a video signal VIDEO. A gradient circuit 212a comprising a diode 201, a resistor 202 and a capacitor 203 generates a gradient subcarrier SC in which the trailing of the subcarrier EXT-SC0 is subject to gradient. A base-emitter voltage VBE of a transistor(TR) 211 changes with temperature and its amplification factor is subject to change. Thus, a level adjustment circuit 212b including the TR 211 changes an amplitude of the subcarrier in response to a temperature change in the BPF 21A to provide an output of an external reference subcarrier EXT-SC. The subcarrier EXT-SC whose amplitude changes with temperature indicates it that the valid pulse width is changed at a threshold level and the subcarrier EXT-SC whose amplitude is adjusted and tilted in this way is equivalent to that the phase is adjusted substantially in the phase comparison in a phase locked loop circuit (PLL).

Title: Charge amplifier
Inventor: ODA MINORU
IPC: H03F1/34
Filed: 1982-04-27
Abstract: PURPOSE:To perform reduction in capacity and to obtain desired temperature characteristics by using plural capacitive elements in combination and thus obtaining feedback capacity. CONSTITUTION:An input current supplied to an input terminal 1 flows to the negative feedback capacity 3 almost entirely through the operation of an amplifier 2. Then, an output voltage proportional to charges integrated by the capacity is developed at an output terminal 4. The output voltage is proportional to input charges. The negative feedback capacity 3 is obtained by using three capacitive elements 3a, 3b, and 3c in combination. The total capacity value of those three elements is less than the capacity value of each element. Consequently, the temperature characteristics of the capacity are selected relatively freely. Since the feedback capacity becomes less, the amplifier has an increased gain, so a superior amplifier as a charge amplifier for radiation measurement is obtained.
