Title: Semiconductor temperature sensitive element
Inventor: OHARA KEISHIN
IPC: H01C7/02
Filed: 1989-10-31
Abstract: PURPOSE:To provide a temperature sensitive element having a desired low resistance value and a desired shape by stacking a plurality of bases and electrically connecting their electrodes in parallel. CONSTITUTION:A thermistor A of a constituent unit of a thermistor B as a semiconductor temperature sensitive element is composed of bases 1 and electrodes 2. The base 1 has positive temperature coefficient for abruptly increasing its electric resistance near Curie temperature, thereby selecting PTC characteristic of the thermistor A and reducing its specific resistance at an ambient temperature by several figures. The upper and lower surfaces of the base l have rectangular or square shape, and coated with ohmic electrode members. A plurality of the thermistors A are stacked, so connected to each other as to be parallel to each other between the electrodes 2, thereby varying the composite resistance value of the thermistor element B.

Title: Formation of electrode wiring of semiconductor device
Inventor: HIRAYAMA MAKOTO
IPC: H01L21/205
Filed: 1988-11-10
Abstract: PURPOSE:To suppress formation of an oxide film and reduce contact resistance between an electrode wiring and a semiconductor substrate by making an atmospheric temperature at the time of inserting the semiconductor substrate into a reaction tube under 500 deg.C. CONSTITUTION:The film thickness of an oxide film to be formed by thermooxidation of a silicon substrate depends on an oxidation temperature. Accordingly, in order to prevent formation of the oxide film on the silicon substrate surface to form a polycrystal silicon film, the temperature of a reaction tube at the time of being inserted into the reaction tube is required to be lowered. Consequently, an atmospheric temperature at the time of introducing the silicon substrate into the reaction tube is made under 500 deg.C. Thereby, formation of the oxide film thickness under the polycrystalline silicon film is suppressed thus being able to reduce contact resistance of the polycrystalline silicon film and the silicon substrate.

Title: Dust discharger for automatic dust remover
Inventor: ONISHI MASATOSHI
IPC: E02B5/08
Filed: 1985-12-18
Abstract: PURPOSE:To scrape down dust adhered to rake plates from both front and back sides of the rake plate by a method in which a wiper is moved not only to one way but also to the back side of the rake plate during the period when a support shaft fixed with the wiper is moved one time in a rocking manner. CONSTITUTION:A wiper 5 is attached to a wiper arm 5c movable back and forth on a support shaft 6 as a supporting fulcrum of the fixed portion. The wiper 5 is moved in a sliding manner while pressing it on a rake plate 3a as a rake 3 goes forward to scrape down dust adhered to the rake plate 3a. In this case, the dust adhered is scraped down to the front side of the rake plate 3a by sliding the front edge 5a of the wiper 5 toward the front claw of the rake 3, and then the back edge 5b of the wiper 5 is moved in a sliding manner toward the back direction from a time when it passes through the rocking lower dead point of the rake arm to scrape dust down. Dust adhered to the rake plate can thus be smoothly discharged without leaving dust unscraped on the back side of the rake plate 3a.

Title: Diode switch
Inventor: KENMOCHI SHIGERU
IPC: H03K17/693
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a compact diode switch by forming at least one of 1st and 2nd transmission lines set in a layered product in a spiral shape and also at least in two layers. SOLUTION: At least one of 1st and 2nd transmissions lines set in a layered product is formed in a spiral shape and also at least in two layers. The line electrodes 107 and 108 are overlapping each other when the upper and lower layers are viewed in terms of projection at a spiral overlapping part (oblique line part) 121. When another spiral overlapping part is added, the length of the transmission line can be shortened. In this example, a diode switch of 900MHz is used and the overlapping rate is set at 13% against the total length. As a result, a 1/4λ transmission line of about 30mm can be reduced down to about 21mm, that is, the length of the transmission line can be reduced to the 70% length of the 1/4λ line.
