Title: Vertical type mos transistor
Inventor: MURAKAMI KOICHI
IPC: H01L29/10
Filed: 1985-02-08
Abstract: PURPOSE:To prevent the breaking of a FET against surge voltage by forming a vertical type MOSFET into a first P well in an N-type Si substrate and connecting a source layer to a second P<+> well. CONSTITUTION:A P well 9 and a P<+> well 27 are shaped simultaneously to an N-type drain layer 3 in an N<+>N-type Si substrate 5, and a P-type connecting layer 33 if formed into the P<+> well 27, and connected to a P<+> type source 13 in a vertical type FET in the P well 9 through an electrode 19. According to the constitution, since a Zener diode 25 is connected in parallel with a source and a drain in a vertical type MOSFET23 and the withstanding voltage of the Zener diode 25 is made lower than that between the P well 9 and an N-type drain layer in the FET25, Zener currents flow first even when comparatively high surge voltage is applied between a source and a drain in the FET, thus preventing the breaking of the FET.

Title: Fuel vapor supply control system
Inventor: ASADA KIYOSHI
IPC: F02M25/08
Filed: 1980-02-27
Abstract: PURPOSE: To reduce the amount of fuel vapor supplied to a suction system from a canister during the normal running by providing a passage which introduces fuel vapor from the canister to the suction pipe when the speed is reduced in addition to a purge passage which introduces fuel vapor to the suction system under the normal running.  
     CONSTITUTION: As the suction pipe negative pressure under the normal running of the engine is below the predetermined level, a valve seat 22 of a negative pressure actuating valve 17 closes a purge passage 23. However, a suction negative pressure acts on an outlet 6 of a canister 1 when the engine is under a load above the predetermined level and the fuel vapor is separated from activated charcol 4 by air sucked from an air inlet port 5 and is supplied to the suction system through a purge passage 10. When the speed is reduced, the throttle valve 11 is almost fully closed generating large negative pressure to lower a diaphragm 18 resisting a spring 21 and opening the valve seat 22, thereby supplying the fuel vapor in the canister 1 to the suction system through the purge passage 23 in large quantity.

Abstract: PURPOSE:To obtain a highly reliable device having an amorphous thin film which shows fantastically low polarizability and has no shift of C-V curve with a leak characteristic of about 10<-12>-10<-10>A by providing said amorphous thin film having a particular molpolarizability in contact with the upper or lower part of metal wiring of a single or more layers. CONSTITUTION:An amorphous thin film having mol polarizability of 0.007-1.00 is provided in contact with upper or lower part of a single layer or more layers of aluminium wirings of MOS device. The mol polarizability of film is set to 0.007-1.00 because if it is 0.07 or less, glass cannot be obtained by ordinary oxide material. When it becomes 1.00 or more, the C-V curve of device shifts toward the high gete voltage side and a leak current also increases. Accordingly, the device characteristic is drasticaly deteriorated. An amorphous film may be formed by any amorphous film forming method including sputtering, electrophoresis method, vacuum-deposition, dipping into the suspension, and reflow method, etc.
