Abstract: PURPOSE:To miniaturize a semiconductor sensor unit, to enable it to be loaded to a time piece, to reduce cost and to improve dimensional accuracy by providing a substrate and a pipe-like member and making the substrate rectangular in shape. CONSTITUTION:A sensor chip 1 which is hermetically fixed to a pedestal 3 is made to softly adhere to the substrate 7 and fixed on the substrate 7 by covering the outside of the chip 1 with the pipe-like member 6 after it is electrically connected to the substrate 7. Next, the chip 1 is covered by laminating a gel-like material 4 and a rubber-like material 5 in order to protect the surface of the chip 1. The sensor unit completed in this way is fixed to the case of the time piece 9 by an O-ring packing 10. Then, the sensor unit is actuated by electrically conducting the substrate 7 and a substrate 12 for the time piece from the back side with the aid of a coil spring 11. At this time, since the substrate 7 is made to be rectangular in shape, the position and the direction of an electric connecting terminal on the substrate 7 are decided when the sensor unit is integrated into the case 9. As the result, the electric connecting terminal can be surely positioned for the substrate 12.

Abstract: PURPOSE:To enable the large reduction of a rotary force of a damper in an air- mixture type air conditioner by opening or closing an upper diffuser and a vent passage by a damper having a circular-arc-shaped outer peripheral surface. CONSTITUTION:Outer or inner atmospheric air 3a or 3b by a blower 1 is dehumidified and cooled by a cooler core 4, is passed through upper and lower temperature control dampers 8, is then joined with hot air passed through the heater core 6 and chilled air at the bypass passge 7 side, and is thus controlled to the prescribed temperature.

Abstract: PROBLEM TO BE SOLVED: To effectively suppress fluctuations (chirps) in oscillation wavelength by distributing the refractive index in the section of an optical fiber forming a diffraction grating so that an envelop which falls off as it goes away from the end face of the optical fiber is depicted. SOLUTION: In the semiconductor laser, a laser resonator is formed using a diffraction grating element 6 placed between the exit-side end face of a semiconductor optical amplifier(SOA) 1 and the plane of incidence of an optical fiber 2. The refractive index of the optical fiber is provided with a specific gradient in the section in which a fiber grating(FG) constituting one of the reflectors of that resonator. In other words, the refractive index is distributed so that an envelope with the refractive index being reduced as it goes away from the end face of the optical fiber is depicted. This is formed by utilizing variation in refractive index which occurs when an optical fiber with Ge added to its core is irradiated with ultraviolet rays.  Owing to this unique constitution of FG, chirps in oscillation wavelength can be avoided, and current-optical characteristic can be stabilized against variation in ambient temperature.
