Title: Manufacture of circuit board with bump
Inventor: ARAKI HIDEAKI
IPC: H01L21/60
Filed: 1992-07-28
Abstract: PURPOSE:To realize a method of manufacturing a circuit board with a bump which does not show any fluctuation in the shape, thickness and pitch of bumps. CONSTITUTION:Green sheets 210, 220, 230 to form ceramics substrate and an unsintered sheet 12 which is not sintered at the sintering temperature of the green sheet are prepared. A hole 10 is made on the unsintered sheet 12 and the hole 10 to form bumps is filled with a conductor 5. The green sheets 210, 220, 230 and an unsintered sheet 12 are laminated and thermally pressed to form a laminated plate. The laminated plate is heated and baked at the temperature for sintering the green sheet to obtain ceramics plates 21, 22, 23 and the conductor 5 is transferred and joined on the ceramics substrate to form a bump.

Title: Stopper device
Inventor: YOKOTA TERUHISA
IPC: B23Q41/02
Filed: 1984-10-22
Abstract: PURPOSE:To shown the time for transport by means of given deceleration, according to a method wherein, when a piston retreats to be released from contact with a pallet part, another part of the pallet is pushed by one end of an actuator lever which makes turning movement with its other end pushed by the rear end of the piston. CONSTITUTION:When a pallet 1 is conveyed in the direction of an arrow mark, a piston 3 is lifted above a feed passage and the pallet 1 stops by hitting a stopper 2 on the lower side of the pallet 1. Then, one end 6b of an actuator lever 6 stays below the feed passage by the effect of a torsion spring 8 and makes no contact with the stopper 2. Then, when the pallet 1 is conveyed to the next work process, if the piston 3 starts descent, the lever 6 turns via a cam follower 7, the piston 3 separates from the stopper 2, and one end 6b of the lever pushes the stopper 2 in the direction of transport to accelerate the pallet 1. Thus, no extra mechanism is required for accelerating the pallet 1.

Title: Branching port rust preventing method and closing device for rust preventing works
Inventor: SAWADA MINORU
IPC: E03B7/00
Filed: 1994-08-24
Abstract: PURPOSE: To provide a branch port rust-preventing method and associate device which can isolate the cut hole of the branch port from the region flowing in a fluid pipe and can perform a rust-preventing process for the cut hole in dry condition or in the atmosphere. CONSTITUTION: A sealed space is formed in a specified part of a fluid pipe 1, and a branch port 13 is formed at the fluid pipe 1 exposed within the sealed space using a certain boring means, and a choking means 14 is inserted into the pipe 1 from the branch port 13 so that fluid flow from the inside of the pipe to the sealing space including the cut hole is checked. Because the cut hole is opened to the atmosphere by disengaging the sealed condition of the sealed space, it is made practicable to apply a necessary rust-preventing process such as drying to the cut hole. After completion of the rust-preventing process, again the sealed space is formed, followed by removal of the choking means, so that no member likely to form obstacle for the fluid flow will remain in the fluid.

Title: Semiconductor device
Inventor: FUJITA ICHIRO
IPC: H01L21/3205
Filed: 1986-09-20
Abstract: PURPOSE:To contrive decrease in wire breaking rate of a wiring layer by a method wherein an intermediate metal layer is provided between each multilayer wiring layer, and it is connected to a semiconductor substrate.

IPC: H04N7/01
Filed: 1991-09-03
Abstract: PURPOSE:To eliminate distortion of a graphic in a reproduced picture by applying same compression or expansion also in the vertical direction in response to the horizontal direction compression rate or expansion rate. CONSTITUTION:The horizontal direction of an object whose aspect ratio is a:b is compressed by using an anamorphic lens and the object is picked up by using an imaging device whose aspect ratio is 3:4, then the video signal is a video image whose longitudinal direction is distorted. A compression ratio K in the horizontal direction is selected to be k-4a/3b. The output is A/D- converted by an A/D converter 1 and its digital output is written in a memory 4 by one field sequentially. In the case of read from the memory 4, an address generating circuit 5 is controlled so as to thinning (3b-4a) scanning lines from the 3b scanning lines in response to the compression ratio K. The digital signal read from the memory 4 by an output of the circuit 5 is subjected to D/A conversion (6) and the result is outputted to a receiver. Since the output signal is compressed in the vertical direction at the same compression ratio as that in the horizontal direction, a video image without distortion is obtained.
