Title: Image reader
Inventor: KURAMOCHI JUNKO
IPC: H04N1/10
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To obtain a high-quality picture free from picture distortion by providing the main scanning reference line, which prescribes parallelism of the Y axis, integrally with an original platen at the time of taking the main scanning direction and the subscanning direction of image read as the Y axis and the X axis respectively. SOLUTION: A document 107 placed on a document plant glass 101 is illuminated by the illuminating luminous flux from a light source 100. Meanwhile, the image of the reflected luminous flux from the document 107 is formed on the face of a solid-state image pickup element CCD 106 through reflection mirrors 102, 103, and 104 by an image forming lens 105. An optical unit 20 in which device parts such as the light source 100, mirrors 102 to 104, the image forming lens 105, and the CCD 106 are built in is put on two scanning rails 109 and 110. It is moved on scanning rails 109 and 110 in the direction (the subscanning direction or the X-axis direction) perpendicular to the element array direction of the CCD 106 (the main scanning direction or the Y-axis direction), thereby scanning the image read position on the surface of the original 107.

Title: Coiled gasket
Inventor: HANAJIMA KANJI
IPC: F16J15/12
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a coiled gasket which has an excellent gas sealing quality and a highly general-purpose quality. SOLUTION: In the case of a scroll gasket which is made up by accumulating metal hoop materials 2 whose sections are of approximate V shapes and a filler material 3 and winding them around in scroll, the relation between an angle α deg. and a radius rmm at each hoop material 2 V shaped tip bending part is constituted so as to become 0.01(α-10)<=r<=0.01(α+10).  It has become clear that the angle of the V shaped tip bending part of each hoop material 2 and the curvature radius of the tip do not affect a sealing quality each independently but affect it while mutually acting on, and in addition it is confirmed that the sealing quality is the most excellent when the relation of r=0.01α is realized between the angle α deg. of the V shaped tip bending part of each hoop material 2 and the curvature radius rmm of the tip, and the sealing quality is inferior even if the radius(r) is larger or smaller than that. But, in consideration of gasket manufacturing unevenness and an error or the like at the time of angle measuring, the angle is made to be within the range of (α deg.±10 deg.).

Title: Correction of fuel injection quantity in warming
Inventor: YAMAGUCHI KEIICHI
IPC: F02D41/16
Filed: 1989-07-29
Abstract: PURPOSE:To surely improve the drivability after start by increased quantity-correcting the fuel injection quantity by the increased quantity correction coefficient corresponding to the cooling water temperature and then revolution speed when the engine revolution speed at each engine cooling water temperature reduces below an aimed revolution speed, exceeding a prescribed quantity. CONSTITUTION:Each of the air-fuel ratio A/F and the engine revolution speed is not markedly different in case of the use of a standard fuel and the use of the lower grade fuel having the higher evaporation temperature, since the fundamental injection quantity is increase-corrected drastically by one after-start increased quantity correction coefficient FSEA immediately after the engine start. As the after-start increased quantity correction coefficient FSEA speedily reduces to zero, the air-fuel ratio speedily changes to lean side, when the fuel injection quantity is speedily reduced, if the fuel having the high evaporation temperature is used, and the engine revolution speed starts reduction. When the difference between the revolution speed at that time and the aimed revolution speed is relatively large, and exceeds a prescribed limit value, the fundamental injection quantity is corrected by the increased quantity correction coefficient FSE and other after-start increased quantity correction coefficient FSEB, and the injection quantity is increase-corrected.
