Title: Dispersion plating method for abrasive grain
Inventor: NAKAOKA YASUYUKI
IPC: C23C18/52
Filed: 1991-04-15
Abstract: PURPOSE:To economically disperse and plate abrasive grains with the uniform degree of dispersion by simultaneously bringing the abrasive grains having specified grain diameter and the other particles different from the abrasive grains into contact with the material to be plated and plating the same, and thereafter removing the other particles. CONSTITUTION:A split member 10 is inserted into the material 3 to be plated which has a groovelike depression. Thereby a plating part is limited and anodes 9 are arranged therein. Abrasive grains 1 such as diamond having >=10mum grain diameter are mixed with the other particles 2 such as glass beads different from the abrasive grains and this mixture is packed into the recessed part. Nickel plating liquid 4 is supplied to this recessed part by a pump 6 and circulated via a filter 5. Thereby the mixture of these grains and particles settles on the bottom part and is pushed on the surface to be plated. In this state, electricity is allowed to flow between the anodes 9 and the material 3 to be plated and plating is performed. Thereafter, the other particles 2 are removed from a plated layer by water washing. The plated layer with the abrasive grains 1 stuck thereto as a single layer is obtained. Thereafter, in accordance with necessity, this plated layer is furthermore built up by nickel plating. Thereby the abrasive grains 1 are strongly fixed on the surface of the material 3 to be plated.

Title: Image display device
Inventor: OKAUCHI TORU
IPC: H01J29/94
Filed: 1989-04-26
Abstract: PURPOSE:To prevent a back electrode from being deformed by tilting of a fixed stand so as to obtain a stable, high quality image by supporting the back electrode at one point on a spherical face portion provided on the fixed stand. CONSTITUTION:A back electrode 39 is supported by means of contact at one point with a spherical face 36A provided over three fixed stands 41 and is supported also against a fixed stand 31 by a curved face 36B in such a manner that it is supported almost at one point thereon. When the back container 40 is deformed by exertion of atmosphere in the D direction the fixed stand 41 is tilted, but, since the back electrode 39 is supported at one point on the spherical face (36A) provided over the fixed stands 41, the contact point of the fixed stand 41 with the electrode 39 only shifts on the spherical face (36B) when the fixed stand 41 is tilted, and so the electrode 39 is prevented from being exerted with a force to deform and is prevented from being deformed.

Title: Fluid driven powder molding device
Inventor: HIRAI AKIRA
IPC: B30B11/04
Filed: 1986-05-14
Abstract: PURPOSE:To produce a molding to an exact size without the variance thereof by the constitution consisting in disposing an upper pestle, mortar hole, lower pestle, elastic block, fluid pressure cylinder and stopper block on the center line of a pair of connecting rods. CONSTITUTION:A piston 62 is held fully contracted, a leg girder 54 of a movable frame 5 is in an up position 54a and the lower pestle 13 mounted to a movable bed 4 and the upper pestle 12 mounted to a head girder 53 are in an up position before the start of the operation. After a feeder 8 engages with the mortar hole 53, the lower pestle 13 descends as well as the piston 62 descends. Powder is then sucked into the mortar hole 11. The upper pestle 12 is brought to the mortar hole 11 by the movable frame 5 which continues to descend further after the retreat of the feeder 8, thus the powder in the mortar hole 11 is pressurized onto the lower pestle 13. This pressurizing force is transmitted via the movable bed 4 to the elastic block 31. The movable bed 4 stops descending upon seating on pressure receiving blocks 32, 33 and further, the movable frame 5 stops descending when the leg girder 54 seats on the stopper block 7. The powder is thus compressed.

Filed: 1990-04-26
Abstract: PURPOSE:To reduce the memory capacity and to improve the memory availability by changing some of a series of document data consisting of plural pages into a substitute page of the original one. CONSTITUTION:When the contents of a connection state storage means 2 are rewritten by a page changing means 3, the document data on the substitute pages are called out in place of the document data on the original pages. Thus some of a series of document data consisting of plural pages can be changed into the substitute pages of the original ones. Thus it is not required to individually store all pages for the documents having partly different page contents in addition to a series of documents consisting of plural pages. Instead it is just required to store the substitute pages only. As a result, the memory capacity is reduced and the memory availability is improved.

Title: Piston structure for reciprocating type internal combustion engine
Inventor: ISHIDA HISAMI
IPC: F02F3/00
Filed: 1986-05-13
Abstract: PURPOSE:To reduce the oscillation of a piston over a wide range extending from a low rotational speed to a high rotational speed of an engine, to aim at reducing noise and abrasion, by displacing the gravitational center position of the piston toward the counter thrust side in the vicinity of the top dead center of the piston, corresponding to the rotational speed of the engine. CONSTITUTION:A weight 4 for regulating the gravitational center position of a piston 1 is disposed, through the intermediary of a weight casing 5, in a downwardly opened space 3 formed in the head 2 of the piston 1. Further, the weight is normally urged downward so as to be pressed against the bottom of the weight casing 5 by means of a compression spring 7. With this arrangement, the weight 4 is raised along the guide surface 5a of the weight casing 5 in the vicinity of the top dead center of the piston 1. As a result, the gravitational center position of the weight is displaced toward the counter thrust side so that the gravitational center position of the piston 1 is also shifted toward the counter thrust side, and therefore, the side pressure distribution of the piston may be made to be uniform, thereby it is possible to reduce the oscillation of the piston 1.

IPC: G01B7/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To improve precision and productivity of a magnetic scale, by constituting an adhesive layer as multilayered structure, making a plurality of magnetic scales in the half cut state, and writing a magnetic signal en bloc. SOLUTION: A magnetic scale 30 is constituted of the following from below; a base layer 33, an adhesive layer 38b, a film 39, an adhesive layer 38a, a nonmagnetic base member 36, a magnetic layer 34 and a protective film 32. The thickness of the protective layer 32 is several μm, and that of the base layer 33 is about 100 μm. It is very different from the conventional ones that an adhesive layer 38 is divided by the film 39. The magnetic scale 30 is stuck and fixed on an object to be detected, after the base layer 33 is peeled, and used by making magneto resistance effect type sensor elements (MR elements) face each other. The adhesive layers 38a and 38b are about 30 μm in thickness, and the film 39 is thinner than the adhesive layers.  It is not necessary that the adhesive layers 38a and 38b have the same thickness, but stable adhesion can be obtained by making the adhesive layer 38b exhibiting fixing function thicker than the layer 38a.

Title: Analyzing system of control path
Inventor: SHIRATORI OSAMU
IPC: G06F9/44
Filed: 1984-05-29
Abstract: PURPOSE:To shorten a compiling time by obtaining a path list containing an advanced control element through the present point together with said advanced control element. CONSTITUTION:A common equation detecting part 4 in a compiler 3 scans the statement within a source module 1 and detects a common equation. An advanced control element deciding part 5 decides an advanced control element at the closest point among those points set in the course to a notice point. While a path list producing part 7 obtains the gathering of flow units with which the control flows between given two points. This path list is saved to a path list table 10 and then used when a path list of a certain range is obtained. Thus it is possible to obtain at a high speed all control paths passing through the points where the common equations exist.
