Title: Air-fuel ratio control device for internal combustion engine
Inventor: NAGAI TOSHINARI
IPC: F02M25/08
Filed: 1994-12-28
Abstract: PURPOSE: To prevent the degradation of exhaust emission caused by the lead-in of purge gas by correcting an air-fuel ratio feedback control constant to the specified value or less when the lead-in of purge gas is discriminated at the time of air-fuel ratio learning control and purge concentration learning control. CONSTITUTION: O2 sensors 31, 32 are respectively disposed on the upper reaches and lower reaches of a catalytic converter 15 in the exhaust passage of an engine, and a fuel injection valve 12 is controlled by computing the fuel injection quantity so that an air-fuel ratio becomes a target air-fuel ratio. Purge gas formed by desorbing fuel from a canister 16 adsorbing the evaporated fuel of a fuel tank 18 is led into an intake system through a control valve 21, but when the lead-in of purge gas to the intake system is detected, an air-fuel ratio feedback control constant computed according to the output signal of the lower reaches O2 sensor 32 is corrected to the specified value or less. The temporary fluctuation of the air-fuel ratio caused by the lead-in of purge gas is thereby prevented, and the degradation of emission is suppressed.

Abstract: PROBLEM TO BE SOLVED: To decrease an amount of effective chlorine to be decreased and to sustain activity for a long period of time by adding a hydantoin compound to brine and subjecting the solution to electrolysis, thereby converting the formed sodium hypochlorite to stable and hardly volatile bond type chlorine. SOLUTION: A hydantoin compound expressed by the formula is added to the brine when the electrolytic chlorine is formed by electrolyzing the brine. In the formula, R1 and R2 are hydrogen or 1-12C alkyl groups which may be the same or different and R3 and R4 are hydrogen, alkali metals or halogens which may be the same or different. 5,5-dimethyl hydantoin is preferably used as the hydantoin compound.

Title: Fabrication of semiconductor device
Inventor: ABE KENJI
IPC: H01L21/3205
Filed: 1992-12-09
Abstract: PURPOSE:To make uniform the hydrophilicity on the surface of an aluminium electrode by subjecting a PSG film to hydrogen annealing prior to wet etching thereby discharging oxygens from the surface of aluminium by means of hydrogens intruding through the PSG film. CONSTITUTION:After removing resist 4, annealing (400-500 deg.C) is performed with hydrogen (hydrogen molecules 7) in order to remove plasma damage. In other words, hydrogen annealing is performed prior to etching of PSG film 2. After hydrogen annealing, the PSG film 2 is removed from a window part by wet etching using a P-SiN film 1 as a mask thus completing an electrode 3 take-out structure. Since hydrogen intruded through the PSG film 2 dispels oxygen from the surface of electrode, hydrophilicity is made uniform on the surface of the electrode. This method allows suppression of overetching when the PSG film 2 is etched.

A magnifying ratio/reducing ratio computer 500 calculates the magnifying ratio or the reducing ratio from the result of retrieval. A picture memory 600 stores picture data 700 and returns the picture to the obtained magnifying ratio and the reducing ratio.

Title: Decorative body for ornaments and method for preparing the same
Inventor: YOSHIDA HIROHIKO
IPC: A44C27/00
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To maintain a state in which the state of decorative body is maintained, as it is for a long period of time. SOLUTION: A silicone resin 5 is placed over an area 2a, i.e., the top surface of an adhesive layer 2, on which beads 4 are disposed, excluding the area for the beads 4. In general, the resin 5 has low adhesion properties and hence dust is hard to attach to the resin 5, and the resin itself has high resistance to oil and hot water so that it is hard to be soiled. The resin 5 has improved weathering properties and has high resistance to ultraviolet rays, and hence the color thereof is hard to change. Since the layer 2 for fixing beads is covered with the resin 5, dust can be largely prevented from attaching to the layer 2 as compared to a conventional layer 2 having no resin layer.  The resin 5 has comparatively low surface tension when it is fed in a liquid state, at the boundary between the beads 4 and the resin 5, the surfaces of the beads 4 near the boundary are covered with the resin 5 and hence the beads can be prevented from being separated after the resin is solidified.
