Title: Method for controlling load at starting of refrigerant compressor
Inventor: FUJIYAMA SHIGEO
IPC: F25B1/00
Filed: 1991-08-14
Abstract: PURPOSE:To prevent component parts of a compressor from being damaged even if the compressor is restarted under a condition in which refrigerant liquid remains in a low pressure system of the refrigerant compressor before its starting by a method wherein a minimum load operation of the compressor is continued only for a predetermined time even after the compressor is started to be accelerated with the load of the compressor being a minimum load and subsequently the operation is controlled in a stepwise manner to increase its load. CONSTITUTION:At the starting time of a compressor for a freezing and air conditioning device having a four-cylinder reciprocating refrigerant compressor, for example, a load of the compressor at an Y-connection stage (Tr time) is set at 25% load as usual and even after its transfer to its A-connection, the 25% load is kept for the time of (t1). Subsequently, the 50% load operation is carried out for the time (t2) and lastly it is controlled to perform a full-load operation. With such an arrangement above, since a refrigerant suction force of the compressor is increased in a stepwise manner from its minimum value even after the connection is changed from the Y-connection to the DELTA-connection, even if the refrigerant liquid is left at a low pressure system of the device before starting its operation, a suction of the refrigerant liquid into the compression chamber of the compressor is dampened. In addition, an electrical current of a motor is also increased in response to a stepwise increasing of the load and an excessive current may not be flowed.

Title: Constant-voltage power source circuit
Inventor: NAGAI KIYOTAKE
IPC: H02H7/20
Filed: 1985-10-16
Abstract: PURPOSE:To perform constant-voltage control at the time of normal loads and cut off a series transistor at the time of an overcurrent, by providing an overcurrent preventing circuit which detects the output voltage of a control circuit and controls a feedback amplifier at the time of an excessive load between the control circuit and feedback amplifier. CONSTITUTION:A load voltage produced across load terminals T3 and T4 is divided by means of voltage detecting resistors 52 and 53 and the output signal of a voltage comparator 51 is inputted to a feedback amplifier 2 through a feedback amplifier input resistance 4 and controls the base current of a series transistor 1. Thus a load voltage is maintained at a fixed level. When the electric current flowing through a current path is increased, the voltage level of a comparing signal outputted from the voltage comparator 51 becomes higher. When the voltage level of the comparing signal exceeds a voltage value determined by an overcurrent preventing operation setting resistor 33 and overcurrent preventing operation setting constant-voltage diode 34, an overcurrent preventing transistor 32 become reverse biases. Therefore, the series transistor 1 is cut off and the electric current flowing through the current path 6 becomes zero.
