Title: Heating device for vehicle
Inventor: KATAOKA KENJI
IPC: B60H1/22
Filed: 1990-11-26
Abstract: PURPOSE:To carry out effective heating by comparing an output value calculated by a computer which receives output signals from a plurality of sensors arranged at intervals in the longitudinal direction thereof, for detecting passengers, with a set value so as to control the heating value of a heating means. CONSTITUTION:Sensors 10 are arranged in a seat 3 at predetermined intervals in the longitudinal direction of the seat 3, and a computer 12 which receives output signals from the sensors 10 through an OR circuit 11 is provided. A control device 13 receives an output value from the computer 12 and compares the same with a set value previously set on a setting unit 14 so as to control the heating value of a heating means 4. When no passenger sits on a passenger seat 3, none of the sensors 10 is energized so that the heating means 4 is operated at a heating value of, for example, 100%. If one passenger sits on the seat 3, the heating means 4 is operated at a heating value of 95%. Further, if three passengers are set on the seat 3, it is operated at a heating value of 85%.

Title: Optical amplificatier device of optical fiber type
Inventor: AOYANAGI TOSHITAKA
IPC: G02B6/02
Filed: 1990-11-26
Abstract: PURPOSE:To stimulate a signal beam with good efficiency by a method wherein, while a stimulated beam is being reflected repeatedly inside an optical fiber and transmitted, a central core is excited and the signal beam is amplified. CONSTITUTION:A signal beam 6 which has been transmitted through an ordinary single-mode optical fiber from a semiconductor laser device in a distant place is introduced into a core 24 in an Er-doped optical fiber 20 for amplifier use. On the other hand, laser beams 38, for stimulation use, which have been radiated from high-without semiconductor laser device 18 are incident into the optical fiber 20 through a reflectionless film 28 from window regions 30. The laser beams 38 for stimulation use enter a clad 26 substantially wholly and reach the core 24 in the Er-doped optical fiber 20; the laser beams 38 for stimulation use are absorbed by the core 24. The laser beams 39, for stimulation use, which have not been absorbed are advance further inside the clad 26, reflected by a highly reflective film 36, advanced again toward the core 24 and absorbed by the core 24 while they are passed through the core 24. Consequently, the core 24 is stimulated and the signal beam 6 can be amplified. Thereby, the signal beam 6 can be amplified with high efficiency.

Title: Carrier plate for microwave semiconductor element
Inventor: ARAI SHIGEMITSU
IPC: H01P5/08
Filed: 1989-12-14
Abstract: PURPOSE:To suppress an influence by a working residue as far as possible and to enhance the characteristic and the yield of a device by a method wherein the area on the surface is made larger than the area of the rear surface of a pedestal and the cross-sectional shape as viewed from at least one direction of the protruding pedestal is formed to be an inverse trapezoid shape. CONSTITUTION:The cross-sectional shape of a protruding pedestal 106 on which a microwave semiconductor element 101 is mounted is formed to be an inverse trapezoid shape. As a result, ends of matching circuits 102 can be situated so as to be close to ends of the microwave semiconductor element 101 which has been mounted on the surface of the protruding pedestal 106. Consequently, the length of bonding wires 105 can be shortened irrespective of the working residue of a carrier plate 103, and the limitation of designing the matching circuits 102 can sharply be relaxed. The size in the lengthwise direction on the surface of the protruding pedestal 106 at the carrier plate 103 can be made to coincide with the size in the lengthwise direction of the microwave semiconductor element 101, and it is possible to prevent the displacement of a mounting position and the nonuniformity of the length of the bonding wires 105. Thereby, the characteristic and the yield of a microwave semiconductor device can be enhanced.
