Title: Control method and apparatus for heat pump freezing cycle
Inventor: YAMAGUCHI SHIGETO
IPC: F25B1/00
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent capability of cooling from being lowered by performing heat exchange between an air suction inlet piping of a compressor or an outlet piping of an indoor heat exchanger and an outlet piping of an outdoor heat exchanger upon cooling operation. SOLUTION: Even when a non-azeotropic refrigerant contains a refrigerant that is lowered in its cooling capability because of temperature lowering upon cooling, heat exchange is performed upon cooling between an outlet piping 6a of an indoor heat exchanger 5 that is an evaporator or an air suction inlet piping 6b of a compressor 1 and an outlet piping 6c of an outdoor heat exchanger 3 that is a condenser. A high temperature refrigerant going out from the outdoor heat exchanger 3 being a condenser toward a pressure reducer 4 and a low temperature refrigerant flowing through the outlet piping 6a of the indoor heat exchanger 5 being an evaporator or through the air suction inlet piping 6b of the compressor 1 are heat-exchanged and are sucked into the compressor 1.  With such construction temperature of the refrigerant likely to become low temperature upon cooling is ensured whereby pressure of the indoor heat exchanger 5 being an evaporator is improved and the amount of circulation of the refrigerant is increased. Hereby, a required load of the compressor 1 is reduced and a greater enthalpy difference is ensured to improve the capability of the evaporator.

IPC: G06F13/42
Filed: 1985-12-20
Abstract: PURPOSE:To simplify control in the transfer direction on a 2-way bus by providing a signal line through which a slave equipment requests transmission to a master equipment and a signal line through which the master equipment designates the data transfer direction to the slave equipment. CONSTITUTION:When a print request takes place in the master equipment 1, the equipment 1 uses a direction control section 1-1 to set a transfer direction signal thereby sending a command and data from a transfer control section 1-2 to a transfer control section 2-2 of the slave equipment 2 via a 2-way bus 3. After print operation, the equipment 2 uses a transmission request output section 2-1 to set the signal line 5 to send the processing status to the equipment 1. The equipment 1 uses the control section 1-1 to judge the priority of transmission request of the equipment 2 and the equipment 1-1 itself, allows the transmission of the equipment 2 and sends the status via a bus 3 from the transfer control section 2-2. Thus, the transfer direction is controlled by a simple logic in this way.

Title: Controlling method for cold impact tester
Inventor: KAWAGUCHI YUSHI
IPC: H01L21/66
Filed: 1989-11-06
Abstract: PURPOSE:To shorten time until the temperature of a test chamber is stabilized and to reduce power consumption by interrupting the output of a heater while heat stored in the chamber and a testpiece is removed by a cooler and the temperature of the chamber reaches a low control temperature. CONSTITUTION:A low temperature chamber 4 is held at a lower temperature than the low control temperature of a test chamber 1 if a damper 9 is closed. Then, when the damper 9 is opened and the atmosphere in a chamber 4 is introduced into the chamber 1, the temperature in the chamber 1 is abruptly lowered. A heater 6 is interrupted at its output simultaneously upon opening of the damper 9. When the heat stored in the chamber 1 and a testpiece 2 to be tested is removed by a cooler 5 and the temperature in the chamber 1 reaches the low control temperature, the heater 6 starts to produce output to control the temperature. Thus, time until the temperature of the chamber reaches the low control temperature is shortened to save the power consumption of the heater and the cooler.
