Title: Air/fuel ratio detector
Inventor: YAMAMOTO TADAHIRO
IPC: G01N27/26
Filed: 1985-12-16
Abstract: PURPOSE:To detect an accurate air/fuel ratio by always calibrating the change of an air/fuel ratio detector with the elapse of time, by allowing a definite amount of air to flow in the stream in the downstream side of a throttle valve in such a state that the speed of the air stream passing through the throttle valve reaches sonic velocity or more to detect the change in air/fuel ratio output. CONSTITUTION:A solenoid valve 27 for allowing air to flow-in is provided on the post stream side of the throttle valve 19 of the suction passage 20 of an internal combustion engine and a detector 23 detecting an air/fuel ratio is provided in an exhaust passage 22. In such an operation state that the speed of the air stream passing through the throttle valve 19 reaches sonic velocity or more, closed loop control is performed by a microcomputer 25 so that an air/fuel ratio reaches a theoretical air/fuel ratio. Next, a valve 27 is opened to allow a definite amount of air to flow in the post stream side of the throttle valve 19 and the change in the output of the detector 23 at that time is stored and, further, closed loop control is performed in such a state that the valve 27 is opened so that the air/fuel ratio reaches the theoretical fuel/air ratio. Thereafter, the valve 27 is closed and the change in the output of the detector 23 at this time is stored and, on the basis of two stored output values, the change in the output of the detector 23 with the elapse of time is calibrated by the microcomputer 25 using a predetermined formula.

Abstract: PURPOSE:To prevent characteristic from being affected by dispersion in the confronting length of an exitation electrode by providing first and second exitation electrodes extending from the short sides on one side and the other side of a piezoelectric substrate, respectively and confronting with each other in the neighborhood of a center in the length direction of the piezoelectric substrate. CONSTITUTION:The first exitation electrode 12 extending from the short side 14 on one side is provided with at least a first area 16 with comparatively narrow width and a second area 17 with width wider than that of the first area 16, and the first area 16 is located at the short side 14 of the second area 17. Meanwhile, the second excitation electrode 13 extending from the short side 15 on the other side is located so as to confront the edge 18 of the short side 14 on one side with the first area 16 of the first exitation electrode 12. The superimposed area of the first and second exitation electrodes 12, 13 is fluctuated only with a small ratio compared with the fluctuation of the confronting length even when the mutual confronting length of them is fluctuated. Thereby, it is possible to reduce influence applied to the characteristic by the fluctuation of the confronting length.

Title: Electrifying roller
Inventor: FURUHATA TOMOKAZU
IPC: F16C13/00
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent the surface layer of an electrifying roller from sticking to a photoreceptor, to prevent toner from melt-sticking to the photoreceptor surface and to prevent the production of abnormal images by constituting a surface layer of a material having a specified range of 100%-elongation tensile strength in the electrifying roller providing the surface layer on a conductive elastic layer. SOLUTION: This electrifying roller is produced by concentrically providing a conductive elastic layer 11 around a rotation axis and further, providing a surface layer 12 on the outer peripheral surface of the conductive elastic layer 11. The surface layer 12 consists of a conductive material having 3.0 to 13.0 MPa range of 100%-elogation tensile strength. If the 100%-elongation tensile strength is less than 3.0 MPa, sticking of the electrifying roller 1 to a photoreceptor is caused. If the tensile strength exceeds 13.0 MPa, melt sticking of residual toner to the photoreceptor is caused under high temp. and high humidity conditions. Abnormal images generate in any cases. In order to electrify the surface of the electrifying roller 1 to a specified polarity and potential, a conductive material such as carbon black is added to obtain 107 to 1012 Ωcm volume intrinsic resistance.

Abstract: PURPOSE:To uniformly apply a photoresist to a whole area where a V-groove is formed by forming an area finished to a specular surface on the inner peripheral side, etc., by bringing itti into contact with the area forming the groove whose cross section is a V-shape. CONSTITUTION:As for a master disk 3 consisting of a metal such as copper, both surface and reverse side are finished to a plane whose maximum average roughness is a prescribed value or below by using a Booray lathe, etc., and subsequently, the surface is finished to a specular surface by a cutting tool whose tip has a curvature. As for an area 2 finished to the specular surface, the area of width of about 5mm on the inside peripheral side of an area 1 in which a V-groove is formed is enough. The V-groove is formed by using a cutting rool whose tip is a V-shape, and on the outer peripheral side of the area 1 where the V-groove is formed, as well, the area finished to the specular surface is provided, and even if a photoresist collects in a boundary part to an area whose surface is rough at the time of final coating and the photoresist becomes thick in width of several mm from this boundary part, it is held in the area 2 finished to the specular surface that the photoresist becomes thick, so that the influence is not exerted on the V-groove formed area 1. In such a manner, the photoresist can be applied uniformly to the whole area where the V- groove is formed.

Title: Manufacture of component in hollow structure and its product
Inventor: YOTSUTSUJI AKIRA
IPC: B29K105/06
Filed: 1988-11-08
Abstract: PURPOSE:To form a hollow part of any shape within a molding easily by a method whereby said hollow part is preliminarily formed by using an alloy melting at a relatively low temperature, fitted in a die, formed of a thermosetting resin before said alloy is melted by heat. CONSTITUTION:For example, a hollow part 3 of a valve component for liquid use is formed of an alloy melting at a low temperature through casting or die casting. If it is further desired that a metallic component or the like is incorporated into the valve component permanently through insert molding, this component 4 is mounted in the molding of the alloy or die. The adjusted metallic component is fixed at a given position in a plastic die. Then, for example, an epoxy resin blended with a thermosetting agent is injected into the die in a manner not to generate air bubbles. After the resin is set, the resultant molding is taken out, and heated in a heating furnace. Since the epoxy resin is resistive to the temperature 80 to 160 deg.C, the metallic component in which the hollow part is formed is formed of an alloy melting in this temperature range.
