Title: Exposure controller
Inventor: KAWAHARA HIDEO
IPC: H04N5/238
Filed: 1989-02-27
Abstract: PURPOSE:To realize a smooth operation and stable stopping control by providing the correction system of reverse characteristic correcting the nonlinearity based on the stopping value of a loop gain of a control system in response to the characteristic of a specific diaphragm, an actuator for stopping drive and an encoder for stopping value detection. CONSTITUTION:A voltage applied to a driver 9 depends on the stopping value of an iris 2 even under the same light quantity change, and the output voltage of a buffer amplifier 12 is large when the iris 2 is in the open state and the movement of the iris 2 is increased. On the other hand, as the iris 2 is stopped, the output voltage of the buffer amplifier 12 is lowered. Thus, the operating quantity of the actuator 10 is corrected to be smaller. Thus, hunting hardly takes place.

Title: Heat exchanger utilizing cold
Inventor: CHINO KOICHI
IPC: F28D7/16
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To ensure stabilized operation over a long time by making a switch to another heat exchanger upon detection of frosting of one heat exchanger and defrosting one heat exchanger when liquid air is produced by cooling the air with LNG using a plurality of heat exchangers and then compressing the cooled air. SOLUTION: LNG in an LNG storage tank is pressurized and gasified by a vaporizer using sea water before being used as the heat source of a thermal power plant or the material of city gas. When power demand has a surplus in night time, a part of LNG is passed to heat exchangers (30-32) in order to cool the air and the cooled air is pressurized by means of a compressor to produce liquid air. The liquid air is utilized when power demand increases in day time. When cold is utilized, heat is exchanged between the LNG and the air, by coupling the heat exchangers 30, 32 and a switching is made from the heat exchanger 30 to the heat exchanger 31 when frosting of the heat exchanger 30 is detected. The heat exchanger 30 is then defrosted by conducting a medium, e.g. sea water.

Title: Semiconductor memory device
Inventor: KUMAGAI YUTAKA
IPC: G11C11/417
Filed: 1980-04-10
Abstract: PURPOSE:To make zero the power consumption of a CMOS semiconductor memory by controlling so that the power source current becomes minimum by a memory-chip nonselection signal regardless of an input signal level when the memory is unselected. CONSTITUTION:When the memory is unselected, namely, when selection signal CS' is held at the high level, the inverter circuit consisting of transistors(TR) Q15 and Q16 holds control signal phic at the low level. In signal input circuit 1, p channel TR Q13 is conducted and n channel Q14 is cut off. Therefore, coupling point P3 is held at the high level regardless of the voltage level of input signal A and the inverter circuit consisting of Q11 and Q12 holds output point P2 at the low level. The level at coupling point P3 is equal to that of power source voltage V and Q11 and Q14 are both cut off, so no power source current flows through signal input circuit 1, making the power consumption zero.

Abstract: PURPOSE:To detect the position of the optical axis changing part of a correcting lens, etc., and to reduce a processing load for a displacement calculation, etc., by providing a displacement calculating part directly calculating the displacement of the optical path changing part based on the count value of a multiplier counter. CONSTITUTION:At the time of each rising and falling of the inputted signals of two phases, a 4-multiplier counter 1-13 uses a phase of other phase to multiply its count value by +1 or-1. Therefore, only the A-and B-phases of an interrupter signal are inputted to the 4-multiplier counter 1-13 to make its count value a value corresponding to a correcting lens position LR. Moreover, counting up and down are not required because of software processing and the count value of the counter 1-13 is only read to detect the position of the correcting lens 8. Its speed can be calculated only by obtaining a variation in the count value of the counter 1-13 at a space of 1ms for a specified time.
