Title: Intake device of engine
Inventor: MIZUNO KATSUMI
IPC: F02B27/02
Filed: 1989-06-14
Abstract: PURPOSE:To improve the intake efficiency from low to high speed by opening and closing opening and closing valves inside long and short pipes, to which respective carburetors are connected, in response to engine speed. CONSTITUTION:An intake pipe 3 which is branched into two pipes, a long pipe 4 and a short pipe 5 are connected to an intake hole 2 of an engine 1. Respective carburetors 8 are connected to the long pipe 4 and the short pipe 5, and opening and closing valves 6, 7 are provided in the long pipe 4 and the short pipe 5. A control circuit 12 is actuated by an ignition pulse of an ignition unit 11 so as to operate the opening and closing valves 6, 7 with a servo motor 13. Only the opening and closing valve 6 of the long pipe 4 is opened at the low speed range, while only the opening and closing valve 7 of the short pipe 5 is opened at the middle speed range. Both the opening and closing valves 6, 7 are opened at the high speed range. Consequently, intake surging wave is used effectively for charging intake air at both the low and middle speed range so as to improve the intake efficiency. Intake quantity is increased at the high speed range so that it is possible to improve the output.

IPC: B41M5/40
Filed: 1986-06-27
Abstract: PURPOSE:To prevent lowering of color forming sensitivity, sticking or contamination of a thermal head from occurring and enhance moisture resistance of undeveloped areas, by providing a specified precoat layer comprising a pigment, an adhesive and a neutral alkali metal salt in specified mixing ratios between a thermal color forming layer and a base. CONSTITUTION:A carboxymethyl cellulose ammonium salt is used as an adhesive in a thermal color forming layer of a thermal recording paper, in an amount of 3-30pts.wt. based on the total amount of a phenolic compound for developing the color of an electron-donative color forming substance and a pigment. A precoat layer comprising a pigment, an adhesive and a neutral alkali metal salt in mixing ratios of 100:5-30:5-30(pts.wt.) is provided between the thermal color forming layer and a base. If the amount of the adhesive based on the amount of the pigment is less than 5pts.wt., printing strength is lowered, whereas if the amount of the adhesive is more than 30pts.wt., the problems of lowering of color forming sensitivity, sticking, contamination of a thermal head or the like will occur. If the amount of the neutral alkali metal salt based on the amount of the pigment is less than 5pts.wt., printing strength is lowered, whereas if the amount of the salt is more than 30pts.wt., moisture resistance of undeveloped areas is lowered.

Title: Biosensor
Inventor: YOSHIOKA TOSHIHIKO
IPC: G01N27/416
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a biosensor which can quickly and easily determine the matrix contained in a sample with high accuracy without being affected by the solid component contained in the sample by providing a reaction layer containing a first enzyme in contact with an electrode system formed on an insulating substrate and a filter layer on the reaction layer. SOLUTION: On an insulating substrate 1, a working electrode 4 is formed in contact with a lead 2 and a ring-like counter electrode 5 is formed in contact with another lead 3. On the surface 1 on which the electrode system is formed a reaction layer 7 containing a first enzyme is formed, in addition, and a filter layer 12 is formed directly on the layer 7. When a sample solution containing a specific component (matrix) is supplied to the reaction layer 7, the matrix selectively reacts with the enzyme in the layer 7. When an appropriate voltage is applied across the electrode system by using an oxidation-reduction enzyme as the enzyme, hydrogen peroxide is oxidized.  Since the then generated response current is proportional to the concentration of the generated hydrogen peroxide, namely, the concentration of the matrix in the sample solution, the concentration of the matrix in the sample solution can be found by measuring the value of the response current.

Title: Exhaust manifold gasket and its manufacture
Inventor: DOBASHI KEIICHI
IPC: F16J15/08
Filed: 1994-06-30
Abstract: PURPOSE:To enhance durability and to prevent gas leaks over a long period of time by making portions of a bead differ in cross-sectional form at the portions of the opening of an exhaust passage that correspond to the long and short sides of a rectangle, and continuously varying the cross-sectional form at portions between the long and short sides. CONSTITUTION:A bead 2d is formed on a sealing plate 2 stacked on each side of a spacer 1 formed of a thin metallic plate. Portions of the bead 2d differ in cross-sectional form according to the distribution of sealing surface pressures; i.e., in P portion shown in the figure, the cross section of the bead 2d is trapezoidal with a slow gradient, while in Q portion the bead 2d rises on a sharp gradient. In corner R, the cross section is formed by a continuously varying curved plane. With the bead thus shaped, a large resisting force is provided where a flange is likely to deflect, and even if deflection is caused by the influence of heat, a sufficient sealing pressure can be obtained to compensate for it.

Abstract: PURPOSE:To automatically complement an incomplete state transition table and to reduce the labor of state transition table generation by providing a means which complements the state transition table at the time when the number of states after transition is '0'. CONSTITUTION:This device consists of a state transition table storage means 101 where the state transition table is stored, a posttransition state number counting means 102 which refers to the means 101 to count the number of states after each transition in the state transition table, and a posttransition state complementing means 103; and when the number of states after transition outputted from the means 102 is '0', the means 103 refers to the state transition table storage means 101 and writes the state of a pretransition state column corresponding to the posttransition state column into this posttransition state column to complete the state transition table. Thus, the pretransition state is referred and automatically copied to complete the posttransition state if the posttransition state column is blank, and the person's labor of state transition table generation is reduced.

Namely, reference voltage OPVRIF is controlled. When the connection destination of the analog switch SW1 is changed from a P2 to a P3, noise is generated in the output of an operational amplifier. Therefore, the generation of noise within an audible band can be prevented by determining a time constant by a R2 and C1 so that the OPVRIF may be slowly changed in voltage when the P1 of the analog switch SW1 is connected to the P3.

Title: Dry etching and device thereof
Inventor: HIROBE YOSHIMICHI
IPC: H01L21/3065
Filed: 1981-09-25
Abstract: PURPOSE:To enhance the efficiency of dry etching treatment preventing an impact to be generated due to electrons and ions, while simplifying the chemical reaction of photo resist by a method wherein a dry etching device is so constituted as to make a nitrogen oxide to absorb ultraviolet rays to be resolved generating oxygen ions in excited condition, and to make the photo resist to be resolved and to be removed. CONSTITUTION:Dry etching is performed by operating a gas supplier 14 and a gas exhauster 18 together to make NO2 gas to current in a reaction tank 11, while irradiating ultraviolet rays from an ultraviolet source 22 to a concave mirror 20. Namely, because ultraviolet rays are reflected for plural times by the concave mirrors 20, 21, NO2 gas to current in space between the concave mirrors is excited and resolved more efficiently than the case when gas is irradiated simply by ultraviolet rays, and active oxygen of high concentration can be obtained. Active oxygen thereof attacks C-C bonding and C-H bonding constituting the photo resist on the surface of a sample 3, and resolves them to produce finally the reaction products of CO, CO2, H2O, etc. As a result, the photo resist is removed to complete dry etching.
