Title: Air conditioner
Inventor: HORIIKE YASUHIRO
IPC: F24F11/02
Filed: 1988-11-16
Abstract: PURPOSE:To prevent high pressure cut even when the water temperature becomes high during heating operation in order to expand the operating range of water temperature by a method wherein a valving device such as a solenoid valve is provided on a water circuit so as to perform on-off control according to the detected inlet water temperature of a water heat exchanger. CONSTITUTION:When a heating switch 14 is turned on, a room fan and a compressor 1 are put into operation. The refrigerant flows from the compressor 1 to a room heat exchanger 3 (condenser) through a four-way valve 2, then reaches a water heat exchanger 4 (evaporator) through a check valve 7 and a heating capillary after condensing in the room heat exchanger 3. When the water temperature rises up to a set value of a temperature switch 17 (35 deg.C for example) though the refrigerant absorbs heat from the circulating water and evaporates, a contact 17a is turned on and a solenoid valve coil 9a is excited, so that a solenoid valve 9 is opened allowing a portion of the water to bypass a heat exchanger 4b and flow towards the solenoid valve 9. The heat exchanging capacity of the water heat exchanger 4 is reduced and the refrigerant does not evaporate, so that both high and low pressure decrease, preventing high pressure cut.

Patent JP-H04167321-A (JP)
Title: Thermally-actuated switch
Inventor: SETO TADASHI
IPC: H01H37/32
Filed: 1990-10-30
Abstract: PURPOSE:To facilitate downsizing of a switch by providing a shape memory alloy spring which is deformed into a previously memorized shape at a prescribed temperature for energizing a second conductor in the separating direction from a first conductor and a balance spring. CONSTITUTION:A shape memory alloy spring 3 is not deformed in its shape to keep a state shown in the figure as long as ambient temperature is lower than a prescribed temperature, therefore, a switch is in an ON state. When the ambient temperature exceeds the prescribed temperature, the spring 3 is contracted due to an effect of a metal phase transformation process, and a second conductor 2 connected thereto is thereby drawn to the right side to be moved against tensile force of a balance spring 4 for separation from a conductor 1. Therefore, the switch becomes OFF. When the ambient temperature again becomes lower than the prescribed temperature, the spring 3 returns from the contraction state and the conductor 2 is drawn by the tensile force of the spring 4 to be moved to the left and brought into contact with the conductor 1. Therefore, the switch again becomes ON.

Abstract: PURPOSE:To make the thickness of an oriented film on a glass base plate uniform and to improve the orientation characteristics of the liquid crystal by forming the oriented film by sticking a sheet made of a resin to the glass base plate. CONSTITUTION:The sheet 3 made of a resin having a uniform thickness is formed in advance and an oriented film 4 is formed on a glass base plate 1 by sticking the sheet 3 to the base plate 1.

Title: Central processing unit
Inventor: HOSAKA KAZUHIDE
IPC: G06F9/38
Filed: 1989-11-13
Abstract: PURPOSE:To detect an error occurred at an instruction decoding part during the execution of an instruction by storing the data to be transferred to an instruction executing part into a FIFO together with the error information via an instruction decoding part and carrying out immediately an exceptional process if the error is produced when the instruction executing part reads the data out of the FIFO. CONSTITUTION:If a bus error is produced when an instruction is fetched by a 2nd immediate operand, an instruction decoding part 1 transfers the operand to a FIFO 2 and simultaneously activates an error occurrence signal 11. Thus, the flip-flop 21 provided on the same stage as a register 22 holding the immedi ate operand is set at '1' and stopped. An instruction executing part, the flip-flop 21 is kept at '1' in the 2nd reading state. Thus the output of an AND gate 32 is set at '1' and an exceptional address generator 35 is activated. Thus, the error produced at the part 1 can be detected during the execution of an instruction.
