Title: Control device for compressor cooling fan motor of refrigerator
Inventor: TAKAGI KOJI
IPC: F25B1/00
Filed: 1993-04-05
Abstract: PURPOSE:To protect the performance of a compressor from being degraded and save energy as well by driving a compressor cooling fan only when required. CONSTITUTION:A microcomputer 3 is provided with an on-timer which records a continuous operation time of a compressor 1 and an off-timer 5 which counts a continuous shut down time of the compressor. When driving the compressor 1, it is necessary to drive a fan motor 2 if an open air temperature detected by an open air temperature sensor 6 exceeds an operation requirement temperature. The operation requirement temperature is computed from a fuzzy inherence, using the continuous operation time and the continuous shut down operation time detected by the timers 4 and 5 as an input condition and set accordingly. The fuzzy control rule is set so that it may be a lower value as the continuous operation time is longer while it may be a higher value as the continuous shut down time is longer. This construction makes it possible to eliminate the waste of time when driving the fan motor 2 and save power and prevent the performance of the compressor from being degraded by operating the fan motor 2 only when required.

Title: Rush current prevention circuit for power amplifier
Inventor: FUNADA ETSUO
IPC: H03F1/52
Filed: 1989-03-31
Abstract: PURPOSE:To prevent a load or an output transistor from being destroyed by a rush current by prohibiting the output of a voltage until a source voltage is increased up to the voltage required for a normal operation at the time of applying a power source. CONSTITUTION:Assuming the Zener voltage of a Zener diode ZD2 as Vz2, a bias is applied to the base of a transistor Q7 from a negative source voltage -B2 via a resistor R4 when the absolute value of the source voltage +B1 is less than Vz2, thereby, the transistor Q7 is turned on. Therefore, the base of a transistor Q5 goes to a grounded state via diode D5 and the transistor Q7, and no negative voltage is outputted to an output terminal 2. In such a way, since no rush current flows at the time of applying the power source, the load or the output transistor can be prevented from being destroyed.

Title: Semiconductor memory
Inventor: KITSUKAWA GOROU
IPC: G11C11/416
Filed: 1982-05-12
Abstract: PURPOSE:To accelerate the discharge of a digit line to prevent the generation of a waveform distortion as well as to shorten the access time, by splitting a cell array to reduce the electrostatic capacity of the digit line. CONSTITUTION:A memory cell array of (n-row X m-column) is split into arrays 1a and 1b of (n/2-row X m-column), etc. The read/write circuits and digit driving circuits 2a and 3a as well as 2b and 3b are provided to arrays 1a and 1b respectively. The contents of arrays 1a and 1b are read out via a detecting/ amplifying circuit 5. The electrostatic capacities of digit lines D0 and D1 are effectively reduced down to 1/2 owing to the split of the cell array, and the discharging speed is accelerated compared with the case where the cell array is not split. As a result, the generation of a reading waveform distortion is prevented along with a reduction of the access time despite an increment of the memory capacity.

Title: Hydraulic control device of automatic transmission
Inventor: GOTO SHIGEKI
IPC: F16H61/06
Filed: 1989-03-31
Abstract: PURPOSE:To prevent shift shock by disengaging one of the friction engaging elements, and raising the duty ratio of the other, i.e., a solenoid valve, when the input shaft of an automatic transmission, in the case of power-on down-shift, exceeds the difference of the product of the number of output shaft revolutions and the Low side gear ratio from the amount of rise delay. CONSTITUTION:In case for ex. 3-2 power-on down-shift is to be made, a duty solenoid valve S2 for C2 is turned off while a duty control valve 11 for C2 is closed so as to disengage a clutch C2. Because the gear train is put in neutral at this time, the number of turbine revolutions of a torque converter 1 is sensed, and when the difference of the product of the number output shaft revolutions of automatic transmission and the Low side gear ratio from the number of turbine revolutions (input shaft revolution) in the portion corresponding to the rise delay is exceeded, the duty ratio of another duty solenoid valve S3 for B1 is raised to a certain value, and brake B1 is engaged through another duty control valve 12 for B1. This prevents generation of shift shocks at the time of kick-down due to blowing-up the engine.
