Patent JP-H025554-A (JP)
Title: Semiconductor device
Inventor: TAKEHARA KATSUNAO
IPC: H01L23/31
Filed: 1988-06-24
Abstract: PURPOSE:To prevent a device of this design from decreasing in reliability even if circuit sections are formed to be large by a method wherein coating films, which seals up the circuit section, are provided separately corresponding to circuit sections. CONSTITUTION:Coating film 11 are formed of synthetic resin such as polyimide resin or the like, which are applied onto each of memory circuit sections 2 separately so as to correspond to the memory circuit sections 2. Usually in a semiconductor chip, a part sensitive to an outer force or the like is only the memory circuit section 2, and the region other than the memory section 2 of the semiconductor chip is formed comparatively high in strength. Therefore, when two or more, for instance, four, eight or sixteen memory circuit sections are provided in parallel to increase the semiconductor chip in memory capacity, the coating films 11 are provided to each of memory circuit separately to make each coating film 11 small in contact area, so that the expansion and contraction difference between the coating film 11 and the semiconductor chip main body 1 caused by the thermal expansion coefficient difference between them becomes small, so that a semiconductor device, whose memory circuit section 2 is protected against a stress which acts on it through the coating film 11, can be obtained.

Filed: 1982-09-07
Abstract: PURPOSE:To suppress the waveform distortion occurring in a Fabry-Perot resonator by providing a transparent protective plate having both end faces inclined relatively with the optical axis between an optical element and an optical semiconductor. CONSTITUTION:Both end faces of the sapphire window 7 of a photodetector are inclined relatively with the optical axis, whereby the formation of a Fabry- Perot resonator between the exit end face of an optical fiber 5 and the end face of the window 7, between both end faces of the window 7 and between the end face of the window 7 and the surface 8 of an optical semiconductor is obviated. The waveform distortion occurring in the Fabry-Perot resonator is thus suppressed.

Filed: 1981-10-02
Abstract: PURPOSE:To economically perform countermeasures against troubles in a device which performs power synthesization by using plural power amplifiers, by making an arrangement that, when troubles occur in an amplifier, the power supply to the amplifier is cut and the operation of the other normal amplifiers is continued. CONSTITUTION:Signals to be amplified are supplied from an input terminal to a power distributor 1, amplified at power amplifiers 2 and 3, and then, outputted from an output terminal 6 after they are synthesized by a power synthesizer 5.

Title: Electric heat fused coupling made of plastic and manufacture thereof
Inventor: UENISHI TORU
IPC: B29C65/34
Filed: 1992-06-17
Abstract: PURPOSE:To improve the reliability and workability of connection by allowing a metal wire at each joint part of an electrical heat fused coupling made of plastic which is formed by embedding the heating metal wire into an inner peripheral part not to be connected with the metal wire at other joint port and to be fused at each joint port. CONSTITUTION:After two jointed pipes 7 are inserted inside a coupling from the coupling ports A and A' on both the sides of a coupling 1, a connector 6 at the top edge of the lead wire of the coupling 1 is connected at the connection part of a controller as electric power source, and a prescribed electric current is supplied to a metal wire 3. The resin in the vicinity of the interface between the coupling 1 and the jointed pipe 7 is molten by the generated heat on the metal wire 3, and the coupling 1 and the jointed pipe 7 are fused. Since the joint ports A and A' form each independent electrical heating circuit, all the joint ports can be formed to an electrical heat fused coupling made of plastic, even if the coupling 1 is a multiport coupling. Further, since each joint port is fused with the jointed pipe 7 by separately putting each joint port into electric conduction, work is facilitated even if the coupling 1 has a complicate shape or in the situation where work is difficult.

IPC: F24F11/02
Filed: 1978-12-25
Abstract: PURPOSE:To air-condition a compartment in a head-cooling and leg-heating type high-level mode by regulating the opening of an air mix door so that the opening can be changed over within a range of the opening that is smaller than an angle of full admission and is larger than an angle of total closing. CONSTITUTION:When rotating a mode change-over lever 22 in the counter-clockwise direction, a link 21 is revolved up to a broken-line location from a full-line location through a connecting rod 23, and a pin P is moved to a point P' along a connecting groove. Thus, a radius of gyration of a lever 20 by a stroke of a working lever 19 increases because a point where the working lever 19 and the lever 20 are connected shifs to the P' from the P. An angle of revolution of an air mix door 10 decreases in response to the increase. Thus, if a range of the revolution of the air mix door 10 at an initial functioning position of the mode change-over lever 22 is beforehand let correspond to a range of auto-opening, the range of the revolution of the air mix door 10 in the case when rotating the mode change-over level becomes narrower than the range of the auto-opening, and a range of opening at a high level is obtained.
