Abstract: PURPOSE:To satisfactorily burn fuel, sharply reduce the discharge of the unburnt component of fuel, and reduce environmental pollution by keeping the air excess ration in a cylinder at a specific value or above to operate a car engine. CONSTITUTION:The air from an air cleaner 1 and the fuel from a tank 4 via a carburetor 5 are fed to a car engine 6 respectively. On the other hand, the exhaust gas of the car engine 6 is discharged via a duct 7. In this case, the exhaust gas is diverted from the duct 7 and guided to an oxygen densitometer 8 to measure the oxygen concentration remaining in the exhaust gas. The fed air quantity is measured by a measuring instrument 3. The air feed quantity is inversely calculated from the target oxygen concentration based on measured results, an air regulator valve 2 is controlled. The air feed quantity is kept at twice the theoretical air quantity or above, i.e., the air excess ratio in the cylinder of the car engine 6 is kept at 2 or above.

Title: Easily openable can-lid having good falling impact resistance characteristic
Inventor: ARAI SHINICHI
IPC: B65D17/28
Filed: 1987-08-03
Abstract: PURPOSE:To simultaneously achieve the enhancement of the falling impact resistance of a can-lid and the reduction of can opening force, by arranging a plurality of projections to the can-lid in the vicinity of the score line of the intermediate part, which connects both ends of the small semicircular score line around a rivet and the large semicircular score line in the vicinity of the outer periphery of the can-lid, in a dispersed state. CONSTITUTION:A plurality of projections 10 are arranged to the panel part 2 in the vicinity of a score line 3c in a dispersed state. The projections 10 suppress the bending deformation along the score line 3c (tensile stress crossing the score line at a right angle) due to the shock generated when a can body falls to achieve the improvement of falling impact resistance. That is, when the projections 10 having this shape are arranged in a dispersed state, the impact force at the time of falling becomes the tensile stress in the normal direction of the projections 10 and is dispersed in all directions and, as a result, the tensile stress component crossing the score line at a right angle can be reduced.

Filed: 1991-08-01
Abstract: PURPOSE:To eliminate the cause of a fault caused by the re-adhesion of a metal at the time of etching by selecting the thickness of a photoresist film on a metallic film so that the etching of the metallic film can be completed when or after a photoresist pattern is removed. CONSTITUTION:After an insulating film 21 and metallic film 22 are successively formed on a GaAs substrate 20, a photoresist pattern 23 is formed by applying a photoresist to the layer 22 and patterning the photoresist. Then the thickness of the pattern 23 on the part of film 22 which is used for forming wiring is reduced to a prescribed thickness by performing anisotropic etching on the pattern 23. After reducing the thickness, the pattern 23 is etched together with the film 22. As a result, the pattern 23 is completely removed before the part of film 22a which is not used for the wiring is completely removed. Therefore, a metal adhering to the photoresist pattern 23 is completely removed at the time of etching together with the photoresist pattern 23.
