Title: Gravure printer
Inventor: MATSUMOTO ISAO
IPC: B41F35/02
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent release and deposition of preprinting ink by providing a plate surface cleaning means for removing an ink film of a non-printing element part of a plate cylinder surface, thereby suppressing an increase of a tack. SOLUTION: In a printing unit 3 of the gravure printer, a plate surface cleaning roller 13 is provided in an ink pan 8 to be brought into contact with a plate cylinder 10. Synthetic resin wires of metal or solvent resistance having suitable hardness of the degree for not damaging the cylinder surface are embedded in an entire circumference on a surface of the roller 13, and rotated with a circumferential speed difference from rotation of the cylinder to brush the cylinder surface. Thus, since it has the roller 13, an ink film of a non-printing element part can be worn off by means of a circumferential speed difference from that of the cylinder. Further, since ink 7 is agitated by rotation of the roller 13, redissolving of the worn-off ink film is expedited.  Accordingly, there occurs no release of preprinting ink due to an increase of tack of the ink film of the non-printing element part.

Title: Vacuum suction chuck
Inventor: NOMURA HIROTOSHI
IPC: B65H3/08
Filed: 1985-03-12
Abstract: PURPOSE:To enable a material to be sucked which has irregular gaps on its surface, to be sucked up by providing valves in each of air passages which connects suction ports with a sealed space so as to allow the passage to be blocked by excessive air flow in such a way that ports which do not contribute to sucking action can be blocked when the pressure drops. CONSTITUTION:The location of at least two or three suction ports 3 is determined so as to allow them to come in contact with a material 1 to be sucked enabling the material to be sucked up. A sealed space 4 is connected with the suction port of a vacuum pump through an electromagnetic valve enabling the pressure to be rapidly dropped by the control of the electromagnetic valve. The suction port out of numbers of them 3 which happens to be located at a gap between materials 1 to be sucked, is automatically blocked because air is violently sucked in from the suction port 3 generating a rapid air flow within an air passage 5 allowing a ball valve 7 to be sucked up and seated on a valve seat 6. Accordingly, this prevents the air pressure in the sealed space 4 from being increased restraining suction force due to vacuum from being decreased.

Title: Wire bonding
Inventor: TAKAHARA MASAHARU
IPC: H01L21/607
Filed: 1984-03-15
Abstract: PURPOSE:To contrive to enhance reliability and yield of junction of wire bonding by a method wherein a clamp mechanism to press and fix a ceramic substrate being interlocked with action of a capillary is provided. CONSTITUTION:A press bar 17 is interlocked with a capillary 11. When the capillary 11 descends onto the surface of a ceramic substrate 15, the bar 17 also descends in parallel with the capillary 11 at the same time. However because the bar 17 is placed at the nearer distance than the capillary 11 to the substrate 15, the bar 17 comes in contact with the substrate 15 earlier than the capillary 11. Therefore, by adding load to the bar 17, no gap is generated between a table 16 even when the substrate 15 has a warp, moreover because action as a spring of the substrate 15 is not generated, absorption of load or an ultrasonic vibration is not generated. Accordingly, bonding of a metal wire and an electrode can be attained sufficiently, and reduction of the ultrasonic vibration or load at bonding time can be prevented.

Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To retreat a belt unit from a processing unit with simple structure by supporting the belt unit movably between a position where the belt unit abuts on the processing unit and a position where it is retreated therefrom. SOLUTION: Plural processing units 9 are supported by a process supporting mechanism 29, and toner is orderly transferred on printing paper at a part where a transfer belt is laid in a straight line state, whereby a full color image is formed on the printing paper. Since the mechanism 29 individually supports plural processing units 9 so that they can freely slide in a direction parellel with the laying direction of the transfer belt and orthogonal to the carrying direction of the printing paper, plural units 9 are individually moved to the side of the belt unit 8. Since a belt holding mechanism 28 supports the belt unit 8 movably between the position where the belt unit 8 abuts on the unit 9 and the position where it is retreated therefrom, the belt unit 8 is retreated from the unit 9.

Patent JP-S50150469-A (JP)
IPC: G09G3/04
Filed: 1975-04-25
Abstract: A horological instrument includes a liquid crystal electro-optical display which simulates the movement of hands about a center by activating circumferentially spaced radial conductive segments. Generally, for the liquid crystal material between two corresponding segments to be activated an electrical potential must be applied between the segments which is, typically to achieve full brightness, substantially greater than the activation voltage of the liquid crystal material. The present invention effects activation of a selected segment-hand by applying an electrical potential, predetermined greater than the activation voltage, between the selected segment-hand and a corresponding segment or electrode. However, the deleterious effects of leakage currents and/or unwanted activation of a segment-hand not selected for activation is reduced by applying an electrical potential between all unselected segment-hands and their corresponding segment or electrode, which electrical potential is predetermined to be less than the activation voltage of the liquid crystal material.

Filed: 1990-02-28
Abstract: PURPOSE:To improve the assembling work, durability, etc., of a crawl frame by forming each elastic member in a circular shape having appriximately the same curvature as that of a ring on the preparation of a crawl frame which is prepared by connecting a plurality of the elastic members each other in the ring shape and which suspends a bottomed cylinder-like net under the crawl frame. CONSTITUTION:A plurality of air-filled hollow elastic members 2 are formed in a circular shape, respectively, having approximately the same curvature as that of a ring so that the hollow elastic members 2 form the ring when all of the members are connected each other. The plural circular elastic members 2 are connected each other through joints 3 into the ring to form a crawl frame 1. A bottomed cylindrical net 4 for receiving cultured fishes is suspended under the crawl frame to form a crawl A. Thereby, when the crawl frame 1 is assembled, works for bending linear elastic members are not necessitated. The durability of the crawl frame 1 can also be improved because bending stresses are not produced in the elastic members 2 after the assembling of the crawl frame 1.
