Filed: 1989-07-20
Abstract: PURPOSE:To enable a stable and economical operation to be carried out within a wide load range by a method wherein the number of revolution changing device is attached between an output shaft of an engine and an input shaft of a compressor. CONSTITUTION:A compressor 3 driven by an engine 2 is mounted within a heating source device 1 acting as an outdoor device. A control device 13 for controlling the number of revolution of an engine, a sensor 14 for sensing the number of revolution, a stator motor 10, a transmission device 11, a transmission ratio changing-over device 12 and a control device 15 are stored in it. A flexible coupling 9 acting as the changing over device for changing-over the number of revolution is placed between an output shaft 2a of the engine 2 and an input shaft 3a of a compressor 3. With such an arrangement, in case that a heating load or a cooling load is quite low, a transmission ratio is changed, the number of revolution of the input shaft 3a of the compressor is reduced lower than that of the output shaft 2a of the engine so as to prevent the engine from performing the surplus operation. As a result, it is possible to prevent the coefficient of operation of the air conditioner from being substantially decreased.

Title: Keyboard input circuit
Inventor: MASUDA TAKAFUMI
IPC: G06F3/02
Filed: 1989-07-21
Abstract: PURPOSE:To converts a character once inputted into another character which is inputted at the time of operating the same key of another input mode by converting the character stored in a temporary storage memory based on a conversion table when an instruction is inputted for conversion of a character into another one of a different input mode. CONSTITUTION:A character string inputted from a keyboard 10 is stored. In such a case, if an operator notices an input mode error and inputs an instruction via the keyboard 10 for conversion into a correct input mode, this conversing instruction is sent to a conversion control circuit 30. The circuit 30 reads the character string out of the memory 20 and replaces the characters of the character string with the correct characters one by one by reference to a conversion table 40. The corrected character string is written again into the memory 20. Thus it is possible to turn a wrong character string caused by the mis-switch of modes or a mode switching mistake into a correct character string with a simple operation.
