Title: Idling rotation control method for internal combustion engine
Inventor: MASAKI SHIYOUICHI
IPC: F02D41/34
Filed: 1981-05-15
Abstract: PURPOSE:To save the fuel consumption by detecting the engine roughness during the idle rotation and lowering the rotation as much as possible while performing the feedback control such that it will be in the allowable variation range. CONSTITUTION:The engine roughness is detected through a vibration sensor  fixed to the circumference of the engine or a rotation variation rate. An injection pump controller 4 will gradually lower the idle rotation during the idle rotation while continuously monitoring the detected engine roughness, and if the  engine roughness will drop below the lower limit the lowering of the idle rotation is stopped to maintain said rotation. Under this state if the engine roughness will increase to exceed over the upper limit, the rotation is gradully increased and when approaching to the upper limit the increasing of the roation  is stopped. When performing the feedback control such that the idle rotation is  lowered to the point where the engine roughness is allowable, the fuel consumption can be saved.

Title: Position detection apparatus
Inventor: HASEGAWA MASAYOSHI
IPC: G03F9/00
Filed: 1992-02-21
Abstract: PURPOSE:To reduce an undesirable influence due to a beam of inessential light which is incident on a photodetection face and to detect a relative relationship between a mask and a wafer by properly setting a method wherein the signal of the detection sensitivity in each region of a detector is processed by using a weight factor. CONSTITUTION:A light flux from a light source 3 is detected by using a detector 38 which outputs a signal corresponding to the light intensity in an incident position of the light flux on a photodetection face via a mask 1 and a wafer 2. Then, the signal from the detector 38 is adjusted, by using a weight factor which differs according to regions, to a signal corresponding to individual regions on the photodetection face from the detector 38. After that, the regions, on the photodetection face, which are to be adjusted again on the basis of an output after the adjustment are reset; the same adjustment is performed. Thereby, a relative position between the mask and the wafer can be detected with high accuracy.

IPC: H01J11/22
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To enhance the light emission efficiency of a plasma display panel in terms of power-consumption to brightness ratio. SOLUTION: In a plasma device panel in which first and second electrodes constituting discharge maintaining electrodes are placed alternately, and which has address electrodes crossing each other via the discharge maintaining electrodes and a discharge space, the second electrodes and the first electrodes located on both sides thereof are used as display cells, and gaps 50 are formed in one or both of the first and second electrodes.  In an ALIS (alternate lighting of surface) method in which X electrodes and Y electrodes serving as discharge maintaining electrodes are placed alternately and a display cell area is formed between the X electrodes on both sides of each Y electrode, gaps 50 are formed in both or one of the X and Y electrodes, whereby a wall charge during a surface discharge can be decreased without reducing the area of a surface discharge between the X and Y electrodes during a maintained discharge. Therefore, the power consumed during the maintained discharge can be reduced without decreasing brightness, while meeting the requirement for high accuracy.

Here because the pallet 1 is provided existing in the upper of a stopper 5, only the rod 12 is displaced for a supporting rod 10 being lifted against an inscribed spring 13, and the stopper 5 is stopped in a position coming into contact with a bottom surface of the pallet 1. Next, when the pallet 1 in the lead passes in its rear head through on the stopper 5, the stopper 5, urged protruding by the inscribed spring 13, rushes into a notch 3. Accordingly, a following pallet 1 is prevented from advancing by the stopper 5, and only the pallet 1 in the lead continues advancing.

Abstract: PURPOSE:To provide an antimicrobial talc composition capable of being safely used for a long period because the dissolution of fixed antimicrobial metal ions in water is little, and giving resin molded products having an uniformly and highly antimicrobial ability because of not discoloring and of having good dispersibility in resins. CONSTITUTION:Antimicrobial metal ions, preferably the ions of at least one metal selected from silver. copper, zinc, tin, lead, arsenic and cobalt, are fixed on safe tale having widely been used as an additive for medicines, cosmetics or foods, or as a filter for resins in an amount of 0.001-15wt.% based on the talk by the adsorption of the ions or by the ion exchange to obtain an antimicrobial talc composition having the above-mentioned activities. Since the talc contains usually water, the tale requires to be dried as a pre-treatment, when added into polyester fibers, etc. But when the composition is further calcined at >=870 deg.C, the composition does not require the pre-treatment. Thus, the antimicrobial talc composition in which the metal ions are carried on the anhydrous tale is obtained and can easily be added to materials which must be maintained in the water-free state.

Abstract: PURPOSE:To decide whether the twisting angle held in a microprocessor is right on the basis of the substantial swing of gauge by arranging a dial gauge such that the tip will contact against a point on the circumferential face of a pitch circle of a gear to be machined. CONSTITUTION:The tip P of a dial gauge 70 will move to the point P' or P'' while maintaining a twist angle beta against the center of work 20 through rotation of a traverse motor (not shown). Consequently, the work 20 will rotate where the rotary angle is determined on the basis of the control data D0 and when the twist angle of work 20 is matching with the twist angle provided when operating, the point P' or P'' is returned to the point P thus to never swing the point of gauge 70. While when they are not matching, the point will swing considerably thus to decide whether the data contained in the microprocessor (not shown) is right or not.

Title: Thermal head
Inventor: TOMIOKA TATSUYUKI
IPC: B41J2/335
Filed: 1986-03-31
Abstract: PURPOSE:To prevent corrosion by providing a chromium film as an electroconductive film having an oxidized coat on the surface which contacts an anti-abrasion film in a region not covered with at least a protective resin coat. CONSTITUTION:A heat-resistant film of TiC-SiO2 is formed on a glazed alumina substrate 1, on which an electroconductive film 3 consisting of an uppermost layer of chromium is formed and subjected to photoetching process. Next the substrate is heated at 330-400 deg.C in a sputtering device and an anti-abrasion film 5 consisting of a mixed film of SiC and Si3N4 is formed in such a way that a heating element 4 and part of the electroconductive film 3 may be covered by the anti-abrasion film 5. After this, a protective resin film 6 is formed so as to cover part of the anti-abrasion film 5 and part of the electroconductive film 3. A thermal head formed in the above-mentioned manner reveals the existence of chromium oxidized film 3a on the surface of the electroconductive film through an Auger analysis of the electroconductive film surface. This is attributed to such a high temperature as 330-400 deg.C in the substrate when the anti-abrasion film is formed. If the temperature is below 300 deg.C, the formation of the chromium oxidized film 3a is insufficient.
