Abstract: A control valve is located in a variable displacement compressor, which is used in a refrigerant circuit. The control valve includes a pressure-sensing member. The pressure sensing member moves a valve body in accordance with the pressure difference between a first pressure monitoring point and a second pressure monitoring point, which are located in the refrigerant circuit. A first spring and a second spring urge the pressure-sensing member in one direction. The spring constant of the first spring is smaller than that of the second spring. A solenoid urges the pressure-sensing member by a force, the magnitude of which corresponds to an external command. The solenoid urges the pressure-sensing member in a direction opposite to the direction in which the springs urge the pressure-sensing member. The control valve quickly and accurately controls the displacement of the compressor.
Abstract: A transmitting circuit splits data to be transmitted into a number of pieces of smaller data, generating packets each used for containing one of the pieces of smaller data with an amount determined by the size of the packet and adding information to a header of each of the packets prior to transmission of the packet to a receiving circuit. Each time the receiving circuit receives any of the packets, the receiving circuit uses the information included in header of the packet to determine whether the packet has been received normally.
Abstract: A reference pressure of melted material injected to a mold cavity of a mold is set as a function of injection passing time from a start of an injecting process or a function of a distance of movement of an injection plunger, and the movement of the plunger is started at a temporarily constant injection speed. A correction value of the injection speed is obtained to eliminate a difference between a sensed pressure of the melted material injected to the mold cavity of the mold and the reference pressure in a range that the sensed pressure of the melted material exceeds the reference pressure during the injection passing time from the start of the injection process wherein the plunger is started to move or during the movement of the plunger, and the injection speed is corrected in accordance with the corrected value.
