Abstract: PURPOSE:To inhibit the generation of a stacking fault in the periphery of patterning, and to suppress a bird's beak by oxidizing a substance, volume of which expands, in a high-temperature oxidizing atmosphere, forming an oxide film and etching an silicon nitride film, using the oxide film as a mask. CONSTITUTION:A substance 4, volume of which expands, is grown in a high- temperature oxidizing atmosphere and three layer structure is shaped before a pad oxide film 2 and an silicon nitride film 3 are grown onto an silicon base body 1 and patterned, the substance 4 and the silicon nitride film 3 are etched and an opening section 5 is formed, and the substance 4 is oxidized and an oxide film 6 is shaped. The silicon nitride film 3 is etched, employing the oxide film 6 as a mask, and a region for preventing inversion is formed into the silicon base body 1 through ion implantation. Accordingly, the volume of the oxide film 6 expands and the oxide film 6 projects to the edge of the opening section 5 when the oxide film 6 is shaped, and film thickness of the periphery of the silicon nitride film 3 patterned through etching, using the oxide film 6 as a mask is thinned, thus inhibiting the generation of a bird's beak.

Title: Control device for hydraulically-operated type transmission for vehicle
Inventor: FURUKAWA HIDEO
IPC: B60W10/11
Filed: 1995-03-02
Abstract: PURPOSE: To perform minute hydraulic control without using an oil temperature sensor by a method wherein the temperature of a refrigerant during the restarting of an internal combustion engine is compared with temperature during following restarting to estimate the temperature of working oil of an operated transmission. CONSTITUTION: Engine cooling water is circulated between an internal combustion engine (E) and a radiator 20 and similarly, an ATF passage 24 to circulate ATF (working oil) is arranged between a radiator 20 and a hydraulic control circuit 0, and heat-exchange is effected between working oil and engine cooling water temperature. Though the change of the ATF temperature is similar to that of an engine cooling water temperature, a deviation therebetween is increased according to a running situation. Especially, when an engine is restarted after the engine is stopped, the changes are not always similar to each other. In which case, when the temperature lowering characteristics of the engine cooling water temperature and the ATF temperature on and after an engine stop are approximate as linear function, it is considered that a proportional relation is established.  When it is decided that a time between a stop and restarting is short, the ATF temperature during starting is estimated from a cooling water temperature during a stop, an estimated ATF temperature, and a cooling water temperature during restarting.

Filed: 1979-06-04
Abstract: PURPOSE:To improve the operating reliability and life of a monolith catalyzer converter by forming a radially extending projection on an inner surface of an annular seal member provided on an end of a catalyzer carrier so as to prevent the seal member from being removed from the catalyzer carrier. CONSTITUTION:An annular seal member 105 has radially extending projections 105a formed on an inner surface thereof. The annular seal member 105 has a pair of such projections 105a disposed on a diametrical line thereof, but it may have three or more projections 105a disposed in circumferentially equally spaced relationship. As it is desirable that an area of an exposed end face of a catalyzer carrier 1 is as large as possible, the total area of the projections 105a is preferably made as small as possible within a range that the seal member 105 is not removed from the end face of the carrier 1 even when the seal member 105 is expanded by heat. By such construction, the seal member 105 can be prevented from being removed from the end portion of the carrier 1.
