Title: Sheet material processor and picture image formation device
Inventor: KOMATSU TERUO
IPC: B65H39/11
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To restrain cost increase due to increase of the number of trays and enlargement of a device and to carry out stable carrying of a sheet material by devising an oscillating member on the upstream side to stay at a position not to obstruct a common carrier passage in the case when an oscillating member to classify the sheet material is the one on the downstream side. SOLUTION: A sheet material recording a picture image is detected by sensors 46, 47 at an inlet part of a common carrier passage by delivering it to a sheet material processor 10. When a solenoid 37 is put on in accordance with signals of the sensors 46, 47, flappers 82, 84 try to oscillate in the clockwise direction, head end parts make contact with the sheet material at the time of their oscillating to a position to obstruct the common carrier passage of the second flapper 82 by tensile force of a tension spring 45 connecting the second flapper 82 and a link 39 to each other. The tension spring 45 is extended by the sheet material, and the flapper 82 stops at a position where it makes contact with the sheet material without obstructing the common carrier passage.  Consequently, it is possible to restrain cost increase and enlargement of a device and to carry out stable carrying of the sheet material.

Abstract: PURPOSE:To satisfy both of output fluctuation and durability by providing a protective layer on a magnetic layer and providing further a porous layer consisting of a material having the hardness smaller than the hardness of a magnetic head and a lubricating layer consisting of a liquid lubricating agent incorporated into said porous layer. CONSTITUTION:This magnetic recording medium has the magnetic layer formed on at least one surface of a substrate, the protective layer which is formed on said magnetic layer and consists of the material having the hardness equal to or higher than the hardness of the magnetic head, the porous layer which is formed on the protective layer and consists of the material having the hardness smaller than the hardness of the magnetic head and the lubricating layer 16 consisting of the liquid lubricating agent incorporated into said porous layer. The coefft. of friction of the layer 16 is 1/5-1/10 coefft. of friction when said layer is flat. The liquid lubricating layer 15 is retained in said layer without starvation for a long period of time. The porous layer 14 forming the layer 16 is formed of the material having the hardness smaller than the hardness of the magnetic head and therefore the wear of the magnetic head is small and even if foreign matter having the large hardness intrudes into the traveling surface, the lubricating layer is injured to protect the magnetic head. The sliding strength of both of the magnetic recording medium and the magnetic head is improved by the combination of the protective layer 12 and the lubricating layer 16.

Filed: 1991-09-20
Abstract: PURPOSE:To replace gas inside a pod without installing a special shielding structure outside a port door by lowering a pod door with the port door being airtightly fit in with a port plate for opening the pod. CONSTITUTION:Between a port door 31 and pod door 21, a space X where a pod door 21 goes up and down X is provided and the pod door 21 is raised and lowered by fixing devices 71-80 housed in the pod door 21 and a fitting recessed section 10B. Because of this structure, when the inside of a pod POD 10 is replaced with the same gas atmosphere as that of a main body case 1, the pod door 21 is lowered with the port door 31 being airtightly fit in with a port plate 3 and then an opening of the pod POD 10 can be opened and therefore a shielding structure such as a bellows is unnecessary. The pod door 21 goes down onto projections 31D of the port door 31 and forms a space with the port door 31. Therefore, the lower face, etc., of the pod door 21 can be cleaned at the time of N2 gas purge.

Title: Molded article made of synthetic resin
Inventor: NAKAMURA SUMIO
IPC: B05D5/06
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a molded article of which the external appearance is not seriously spoiled even when the side to be looked at of the article is damaged by the collision with an obstacle, etc. by coating the backside of a transparent or translucent substrate with a coating material containing very fine bright chips dispersed therein to form a coating film and by using the front side of the substrate as the side to be looked at. SOLUTION: The backside of a substrate 2 made of a transparent polycarbonate resin or the like is degreased and then coated with a transparent intermediate coating material, e.g. a polyurethane-based one, containing a great number of very fine bright chips dispersed therein with a spray apparatus to form a transparent coating film layer 3a, i.e., the first coating film layer, on the backside of the substrate 2. Then, on the surface of the transparent coating film layer 3a, an opaque colored coating material is applied to form a colored coating film layer 3b, i.e., the second coating film layer, which is baked.  For example, in an automotive operation panel having the backside covered with a coating film layer 3, the front side of a substrate 2b is used as the side M to be looked at, and since the substrate 2 is thick, the coating film layer 3 is not shaved off even when an obstacle or the like collides, though the front side of the substrate 2 is damaged.

Title: Manufacture of semiconductor device
Inventor: KUBOTA SHIGERU
IPC: H04N5/335
Filed: 1984-11-15
Abstract: PURPOSE:To manufacture the image sensor products offering the high-sensitivity and high-quality picture by high yield and at low cost by covering the part of light transmitting glass necessary for an image sensor with a metallic thin film layer. CONSTITUTION:After a metallic thin film layer 18 is formed on the part of a sealed side 11-1 of a light transmitting cap 11, a sealing material 12 is formed. Because that metallic thin film layer 18 covers the light transmitting cap plane, a deposition of the sealing material or a scratch under 10mum is confined to the metallic thin film layer and it does not reach the light transmitting cap plane. Accordingly, by peeling the metallic thin film layer, the production is carried out without decreasing the yield because of adhesion of foreign matters or a scratch of the plane of the light transmitting cap even if the light source for the high-sensitivity and high-quality picture becomes parallel lights.

Title: Testing means for immunoassay
Inventor: NARITA EIJI
IPC: G01N33/543
Filed: 1988-09-27
Abstract: PURPOSE:To provide a simpler structure, lower price and smaller size and to facilitate the operation for immunoassay by depositing an antibody or antigen in a fixed state and a labeling antibody or antigen in a non-fixed state on the same water absorptive carrier. CONSTITUTION:The testing means 1 for immunoassay has the water absorptive carrier 3 which carries the antibody (or antigen) 2 bondable with a material (specimen) to be detected and carries the labeling antibody (or labeling antigen) 5 in the non-fixed state. The testing means is extremely convenient for operation if this water absorptive carrier 3 is previously mounted on a handle 4. This water absorptive carrier 3 is impregnated with the specimen such as urine by a method such as dipping or dropping and after the reaction is effected for a specified period of time, the labeling antibody or labeling antigen which does not react is removed by washing. Decision is made by bringing the composite and the substrate into reaction to cause color development. Since the penetration of the specimen into filter paper is merely necessitated, the operation is hygienic and the measurement with a small volume of the specimen is possible.
