Title: Method for producing cut photosensitive planographic plate and method for producing stack of cut metallic thin plate
Inventor: ITO MASAHITO
IPC: B26D1/06
Filed: 1996-01-25
Abstract: PURPOSE: To reduce the rate at which inferior product quality arises due to dull cutting blades by stacking a plurality of photosensitive planographic plates having a photosensitive layer formed over their metal support, and cutting the stacked photosensitive planographic plates with a cutting blade having a specific coefficient of friction. CONSTITUTION: When a plurality of photosensitive planographic plates 7 having a metal support and stacked are placed on a stand 5, the plates 7 stacked are made to abut to a back stopper 3 and aligned, and a cutting blade 1 is lowered in the vertical direction relative to the stand 5 by a cutting-blade drive to cut all the planographic plates 7 at a time. The plates 7 stacked are held from above by a stopper 2 that can be moved vertically via a spring 23, to ensure a stable cutting operation. In such a cutting method, the flank 12 of the cutting blade 1 is made to have a coefficient of friction of 0.3 or less, and for that purpose the flank 11 of the cutting blade 1 facing a product 71 is coated with wax, fatty-acid wax, or the like as necessary.

Title: Air-fuel ratio detecting device for internal combustion engine
Inventor: UCHIKAWA AKIRA
IPC: F02D41/34
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To avoid the influence of variations in each sensor when an air-fuel ratio is detected using a wide range air-fuel ratio sensor. SOLUTION: The output power V of an air-fuel ratio sensor (S1) is read, by referring to a reference table, is converted into an air-fuel ratio λ0 (S2). On the other hand, the variation ΔV of the output voltage of an air-fuel ratio sensor until a specified time elapses since the start of fuel cut is learned and correction data k=ΔV/ΔV0 is prepared by comparing the ΔV to a reference variation ΔV0 (S3 to S9). The air-fuel ratio λ0 is corrected by the correction data (k) to obtain a true air-fuel ratio λ=1+(λ0 -1)/k (S10).

IPC: F02D9/02
Filed: 1985-01-23
Abstract: PURPOSE:To enhance air-intaking efficiency for every operating condition by constituting the system in such a manner that as the engine rotating speed increases a valve operates so as to open an air-intaking passage and as the engine rotating speed decreases the valve operates so as to close the air-intaking passage.

Title: Asymmetric misconvergence correcting device
Inventor: TAKAGISHI TOSHIYA
IPC: H01J29/76
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To correct an asymmetric misconvergence with a simple structure while giving no effect on the coma correction. SOLUTION: At the rear end side of a vertical deflection means, a correcting means 40 to correct a misconvergence generated by a vertical deflection magnetic field is installed to a CRT tube surface 12c. This correcting means 40 is composed of a pair of cores 24 and 26 provided at both sides of the tube surface, and correcting coils 28 wound on them. The correcting means 40 is composed movable to the CRT tube surface 12c. The vertical below asymmetric misconvergence is corrected by moving the correcting means 40 in the horizontal scanning direction to the CRT tube surface 12c, and the right and left asymmetric misconvergence is corrected by moving in the vertical scanning direction.  Since the asymmetric misconvergences can be corrected by regulating the opposing position of the correcting cores to the CRT tube surface 12c, no influence is given to a coma correcting magnetic field itself, even though a coma correcting means is used. Consequently, the asymmetric misconvergences can be corrected independently, without giving an influence to the coma correction.

Title: Electrochemical measuring method of analyzed material or oxidoreductase and sensor electrode system
Inventor: YOAHIMU HENESU
IPC: C10M133/50
Filed: 1991-02-02
Abstract: PURPOSE: To electrochemically measure at a low potential without danger of disturbing reaction by differentiating the substance formed by oxidation at an electrode from reducible substance used first. CONSTITUTION: Analyzing material itself is oxidized by oxidereductase, and hence formed with corresponding enzyme substrate or the material is converted to compound capable of being oxidized by the oxidereductase in one or several preliminary reactions or preferably enzyme reaction. The electrons generated during the oxidation are proportional to the quantity of the material to be measured. When the electrons are moved to the electrode by reducible substance, it introduces the scale relative to the material to be measured. Thus, the reducible substance is reduced in an enzyme manner, oxidized at the electrode. Since the oxide substance different from the substance used at the initial as the reducible substance is formed at the electrode, electrochemical measurement can be conducted without danger of disturbing reaction particularly at a low potential.
