Title: Light source for variable wavelength semiconductor laser
Inventor: NAGASHIMA SHINYA
IPC: H01S5/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide precise wavelength accuracy by providing an outer resonance-type semiconductor laser light source part, a driving part, first - third optical couplers, an acoustooptic element, an etalon and a transmissivity measuring part. SOLUTION: The first optical coupler 4 branches outgoing light from the outer resonance-type semiconductor laser light source part (light source) 1, outputs one light, makes the other light incident on the second optical coupler 5 and branches it. One branched light is made incident on the acoustooptic element 7 and the other light is made incident on the third optical coupler 6. In the acoustooptic element 7 and a photodiode array part (PD) 9, signals corresponding to the wavelength of incident light are outputted and they are outputted to a control part 3. The optical coupler 6 branches incident light and makes one light incident on the transmissivity measuring part 11 through the etalon 10.  The transmissivity measuring part 11 obtains the transmissivity of the etalon 10 from the transmission light of the etalon 10 and the other incident light branched in the optical coupler 6 and outputs it to the control part 3. The control part 3 controls the driving part 2 so that a wavelength value becomes that which is set to the light source 1 from the signal of PD 9 and the transmissivity of the transmissivity measuring part 11.

Title: Method of controlling operation of compressor
Inventor: SUZUKI SHINICHI
IPC: F04B49/10
Filed: 1987-10-13
Abstract: PURPOSE: To suppress abnormal inner temperature rise of a compressor at the time of low load operation while reducing vibration and noise by providing a delivery temperature detector for the compressor and enlarging the opening of a suction throttle valve upon detecting abnormal delivery temperature rise of refrigerant incident to throttling operation of the suction throttle valve. CONSTITUTION: When a room is cooled sufficiently by cooling operation, an expansion valve 4 begins throttling action to operate a compressor 1 under low load. Consequently, refrigerant pressure from an evaporator 5 decreases and a valve disc 15 is projected projected in the throttling direction through action of the compression spring 16 in suction throttle valve 6 to reduce refrigerant flowing into the compressor 1. When the inner temperature of the compressor 1 rises to cause abrupt refrigerant temperature rise on the delivery side 1a, a delivery temperature detector 22 detects that temperature and delivers a drive pulse signal 21 of duty ratio corresponding to the detected temperature to the coil 19 of an electromagnet 17 through a control circuit 23.  The valve disc 15 is shifted in the opening direction by an amount corresponding to the duty ratio thus enlarging a refrigerant passage.

In this air conditioner the position of the remote controller is detected and as the detected position goes farther from an indoor unit the amount of air and the air velocity are increased so that sufficient air reaches a person living in the room even if he is far away from the door unit. It is, therefore, possible to attempt to improve pleasantness of a living space with attention centered on the person living in the room and shorten the time of room heating operation.
