IPC: F01N3/24
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To heat a catalyst to the optimum condition in response to the nature of fuel by providing an electrical heating control means which determines the working time of an electrical heating means forcibly heating the catalyst in response to the nature of fuel detected by a fuel nature detection means, and thereby controls the electrical heating means based on the determined operating time. SOLUTION: An electric heating catalyst(EHC) 2 and catalytic converter rhodium 3 to be heated by exhaust gas are disposed in order in the exhaust system of an internal combustion engine 1, an electric heating means 4 forcibly heating the EHC is adapted to the EHC 2, and electric power from a battery 5 is fed thereto under the control of an ECU 6. The ECU 6 judges the nature of fuel on account of a fuel nature correction factor computed based on the quantity of fuel vapor.  An operation time correction factor is determined based on a fact that the heavier fuel in nature is less subject to a smaller fuel nature correction factor so as to allow the operation time correction factor to be proportional to the nature of fuel, a basic operation time is multiplied by the operation time correction factor, and thereby a heating operation time is computed, so that the switching-on to the electric heating means 4 is thereby controlled.

Title: Tube stored in living body
Inventor: UEDA YASUHIRO
IPC: A61L31/00
Filed: 1989-12-19
Abstract: PURPOSE:To prevent an inner cavity from being imperforated so as to greatly prolong the period during which a tube is stored in a body cavity by forming the inner surface of the tube from a material having adaptability to living body and the ability of preventing adhesion. CONSTITUTION:An ERBD tube 1 has a plurality of flaps 2 diagonally cut therein and extended near both end portions thereof and an adhesion preventive layer 3 formed on the inner surface thereof. High water bearing rubber used as the adhesion preventive layer 3 exhibits elongation percentage similar to that of ordinary rubber by repeatedly freezing and thawing a PVA aqueous solution, and this rubber is excellent in adaptability to and scarcely adheres to living body. When the ERBD tube 1 is inserted into ductus choledochus from a duodnum using an endoscope the flaps 2 are engaged and fixed in the wall of a body cavity so that a discharge passage for bile is secured in a biliary duct where structure is caused by gall bladder cancer etc. Because the adhesion preventive layer 3 is formed on the inner surface of the tube, imperforation due to adhesion and solidification of bile is prevented. Also, imperforation due to attachment of digested substances flowing back from the duodnum to the biliary duct is prevented.

Abstract: PURPOSE:To obtain a method for manufacturing a solid-state image pickup device capable of preventing the characteristic deterioration due to the microminiaturization of the solid-state device, and at the same time, making the production control easier. CONSTITUTION:On a silicon substrate 11, a polysilicon gate 13 is patterned through a gate insulating film 12; on the surface of the polysilicon gate 13, an interelectrode insulating film 14 is formed; and a polysilicon shift electrode 15 is patterned.

Compared to conventional normal-pressure SiO2 films, the film thickness of this LP-SiO2 film 17 can be made small, and at the same time, its film quality is made superior. Therefore, when a reflow film 18 and a light shielding Al electrode 19 are formed, it is possible to prevent diffusion of contamination from the reflow film 18. Also, since the distance between the edge of the light shielding Al electrode 19 and the silicon substrate 11 can be shortened, the smear characteristic can be improved.
