Title: Temperature controller
Inventor: MASUDA SHIGEFUMI
IPC: G05D23/22
Filed: 1984-07-13
Abstract: PURPOSE:To increase the response speed and to improve the control accuracy by using an integration circuit which controls continuously a Peltier element with a metallic oxide film gate field effect transistor and also switches a time constant with a changeover switch. CONSTITUTION:A temperature detection part 1 consists of a thermocouple 11 and a converter 12; while a temperature setting part 2 for manual setting a control target temperature includes a setting part 21 and an operational amplifier 22. The difference between the output signals of parts 1 and 2 is amplified by a differential amplifier 3. These output signals are integrated by an integration circuit 4. This integrated signal drives a metallic oxide film gate field effect transistor Tr6 via an operational amplifier 5. Then a Peltier element 7 is controlled. The circuit 4 contains a changeover switch 41 using a Tr and two circuits of different time constants. Then the circuit of a smaller time constant is used until the output of the amplifier 3 reaches a prescribed level. Thus the response speed is improved.

Abstract: PURPOSE:To obtain a key input circuit which is suitable for a PB telephone set and, at the same time, which is stable and operable at such a low current consumption that can be applied to a semiconductor integrated circuit, by using a constant-current source using MOSFETs and charging and discharging a capacity. CONSTITUTION:Of each current source composed of MOSFETs, one current source I4 discharges input terminals Rn and Cm and capacities CIn and CIM to '0' at The timing of the pulse impressed upon a terminal T6 immediately after another current source I1 charges the input terminals Rn and Cm and capacities CIn and CIm to '1' at the timing of the pulse impressed upon a terminal T3. Thereafter, the output XRn of a latch Ln becomes '0' in order to raise the strobe STBn of the latch Ln.

Title: Chrominance signal correction circuit
Inventor: MINAMI NORIAKI
IPC: H04N9/79
Filed: 1986-06-20
Abstract: PURPOSE:To obtain a chrominance signal correcting circuit capable of omitting the equipment of an 1H delay line by converting the frequency of a reproducing low level conversion carrier chrominance signal based on a reference subcarrier signal outputted from a burst sequence continuing circuit. CONSTITUTION:An output of a frequency converter 80 is inputted to a sub-BPF 24 through a main BPF 23 and an inversional amplifier 25. The passage center frequency values of the main BPF 23 and the sub-BPF 24 are set up to the sum and difference between the carrier chrominance signal and the subcarrier signal. Since the passage center frequency of a BPF 11 in a frequency converting circuit 1 is the reference subcarrier signal, a complex conjugate signal corresponding to a chrominance signal in a PAL system is obtained from the BPF 11 by turning a switch 9. Consequently, the rearrangement of a burst sequence is applied to the carrier chrominance signal C sent from the circuit 1 to a color vurst insertion circuit 3. Thus, the signal C be prevented from color disappearance or the like at the time of specific reproducing by reinserting an inner color burst through the circuit 3 in stead of a real color burst.
