Title: Fuel injection pump for diesel engine
Inventor: AIYOSHIZAWA EIJI
IPC: F02D41/40
Filed: 1989-05-19
Abstract: PURPOSE:To restrain any uniformity of an injection quantity in an idle operation or in a slow rotation at a low load by providing a mechanism for fixing a timer piston at an operation region (slow rotation region at a low load) where the phase of a face cam is advanced and a fuel pressure in a pump chamber is decreased. CONSTITUTION:A fuel injection pump provided with a timer mechanism for advancing or delaying a phase of a face cam consisted of a timer piston 22 and a control valve 31 transmits a deviation of the timer piston 22 to a roller holder via a connecting lever 21 so as to turn the roller holder within a specific controlled angular range. The control valve 31 is disposed on the way of a fuel passage 28 for intercommunicating the high and low pressure chambers 23, 26 of the timer piston 22 to each other, to be thereby opened or closed on the basis of a drive signal. A motor 44 driven upon judgment of a slow rotation at a low load is disposed. A bolt 42 is projected near the upper end of the timer piston with power of the motor 44 so that any vibration of the timer piston 22 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To improve the adhesive strength of a plating layer by plating the sulfidized surface of the body to be plated with colored metal composed of a prescribed allay by vapor deposition. SOLUTION: As the body to be plated, the material in which at least the surface layer contains silver and/or copper is used as the object. In the primary stage, the surface is subjected to sulfidizing treatment. As for the treatment itself, the conventional technology may be adopted as it is. In this way, a layer of sulfide of constituting metal for the body to be plated such as silver sulfide, copper sulfide or the like with many fine pares is formed on the surface of the body to be plated. In the secondary stage, a prescribed surface region is plated with at least one or two kinds selected from gold, silver and gold-silver by vapor deposition. As for the method of the vapor deposition itself, the conventional technology may be adopted as it is.  For example, with only the plate requiring the vapor deposition left, the balance is coated with metallic foil, and the vapor deposition is executed. After the completion of the vapor deposition, the metallic foil is removed, and the vapor-deposited material is cleaned in an organic solvent and is dried.

Filed: 1979-09-29
Abstract: PURPOSE: To enable sure discrimination of an object by a method wherein the light is applied in parallel to the direction of the grain shaped on the surface of copper leaf of the printed substrate and thereby the irregular reflection on the surface of copper leaf is reduced.  
     CONSTITUTION: On the printed substrate 1 is fitted copper leaf to form a surface 2 to which chip parts are to be fitted.

Title: Calculation of surface dimension
Inventor: SADAKANE MICHIHIRO
IPC: G01B21/20
Filed: 1989-05-19
Abstract: PURPOSE:To detect the surface dimensions correctly thereby to save labor in a checking process by moving a spherical stylus on a normal line of the surface of said stylus by the amount corresponding to the difference in radius between a virtual spherical stylus and said actual spherical stylus. CONSTITUTION:A spherical stylus (h) which is used to detect the surface dimensions of a work W is placed at the initially-set position of coordinates. The spherical stylus (h) has a smaller diameter than a virtual spherical stylus H. The center of the stylus (h) is positioned on the basis of the coordinates of the initially-set center. As the stylus (h) is moved from this position, the change of coordinates is read. Accordingly, the changed coordinates to the coordinates (Z1,X1) where the initially-set stylus (h) abuts on the surface of the work W are obtained from a square root of the sum of squares on each axis. Therefore, if the coordinates of the center of the stylus (h) are obtained based on the moving amount corresponding to the difference in radius as a reference, it can be detected whether the work W remains to be further processed or it is processed too much and bitten.

Abstract: PURPOSE:To enable the tracking capable of following a track bend by displacing simultaneously 1st and 2nd posts which are connected by a connecting means and moving a tape-like recording medium back and forth in its traveling direction upon a rotary head drum. CONSTITUTION:When the post 18 is displaced in the relaxing direction of the magnetic tape 50 on the inlet side of the rotary head drum 10, the post 23 is simultaneously displaced in the stretching direction of the magnetic tape 50 on the outlet side of the rotary head drum 10 by the same amt. Consequently, the magnetic tape 50 is moved between the post 18 and same 23 along the traveling direction from the inlet side to the outlet side of the rotary head drum. On the contrary, when the post 18 stretches the tape 50, the post 23 slackens the tape 50. Since the displacement amts. of the post 18 and same 23 are the same, the magnetic tape 50 can be moved back and forth in its traveling direction without giving a large tensional variation.
