Patent JP-H01196461-A (JP)
Title: Freezer
Inventor: HIRANO AKIHIKO
IPC: F25B1/00
Filed: 1988-02-02
Abstract: PURPOSE:To prevent a liquefied coolant from being absorbed into a compressor at the time of starting the operation of the freezer by disposing a liquid receiver at a position lower than an evaporator so that a head is produced between both apparatuses, and connecting the outlet side of the evaporator to the liquid receiver by a pipeline having a valve mechanism. CONSTITUTION:Immediately after stopping the operation of an automatic ice making machine, a pressure difference remains at a high-pressure liquid receiver 3 and the outlet side of a low-pressure ice making member 6, but the pressure difference is removed gradually by a gas leakage and finally the pressures are unified. When the pressures are unified, a check valve 8a which has been closed by the pressure difference is opened because a valve 18 descends from a valve seat 17 by its own weight. Since the liquid receiver 3 is provided by providing a head with respect to an evaporator constituting an ice making member 6, a liquefied coolant stored within the ice making member 6 flows into the liquid receiver 3 by the gravity. That is, during the storage of the operation of the automatic ice making machine, no liquefied coolant exists in the evaporator constituting the ice making member 6, and hence, at the time of resuming the operation, the liquefied coolant is not absorbed in the compressor.

Title: Semiconductor storage device
Inventor: RYU YASUSHI
IPC: G11C16/06
Filed: 1989-01-31
Abstract: PURPOSE:To improve the yield in promoting the degree of integration of a whole chip by selecting either data from a 1st storage part or a 2nd storage part to be outputted, separating and arranging the 1st and 2nd storage parts from each other. CONSTITUTION:When a defective cell is found in a mask ROM cell array 16 of the 1st storage part 18, a redundant address showing this defective cell is set in a redundancy deciding circuit 13, and moreover the same data as a data to be written in a cell with a capacity of one row including the defective cell is written by a write control circuit 19 to a PROM cell array 23. Then, when an inputted address signal is conformed with the redundant address, a data of the side of the 2nd storage part 24 is selected by a selection circuit 25 to be outputted. Consequently, the 1st storage part 18 and the 2nd storage part 24 are separately arranged, and neither word lines nor bit lines are shared at all. By this method, a defective can be relieved by the storage part 24 while the degree of integration of the 1st storage part 18 is insured, and the yield is thus improved.

Title: Self-diagnostic system for a/d conversion section of microcomputer
Inventor: NOMOTO KAZUNORI
IPC: G06F3/05
Filed: 1990-01-30
Abstract: PURPOSE:To attain clear fail processing discrimination of an A/D converter section by inputting a power voltage and a reference voltage fed to the A/D converter section from separate circuits. CONSTITUTION:An A/D-converted value being a half the inputted power supply voltage is compared with an upper limit value (RMAX) and a lower limit (RMIN) respectively and when the limit is exceeded, an error processing of the A/D converter section is implemented and when the limit is not exceeded, a normal processing of the A/D converter section is implemented. Since the power voltage and the reference voltage are inputted from separate circuits, i.e., a power supply circuit 15 and a reference voltage generating circuit 16, a standard power supply circuit is adopted for the power supply circuit 15 and a highly accurate circuit is employed for only the reference voltage generating circuit 16. Then a highly accurate and inexpensive IC or the like is used for the reference voltage generating circuit 16 to easily realize the discrimination of the absolute voltage of the said analog sensor 12.

Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a circuit component mounting system for inspecting a mounting state at each mounting of a circuit component on a printed board. SOLUTION: Each time a circuit component is temporarily mounted on a printed board 20, a relative position between the component just temporarily mounted and the board 20 is measured based on an image captured by a slit light emitting unit 190 and a CCD camera 194. A slit light is emitted obliquely to the surface of the board 20, and a positional deviation of the component in a direction perpendicular to a parallel direction on the surface of the board 20 can be measured. The temporary mounting state is inspected immediately after temporarily mounting, and the position of the component is corrected before treating by the solder reflowing furnace of a rear stage from the inspected result. And, a special purpose inspecting unit is not necessarily provided before or after the treatment by the furnace, and hence a facility cost can be reduced.
