Patent number: 6105495Abstract: In a screen printing apparatus and method for using a squeegee to press printing paste on a screen while moving the squeegee in the horizontal direction in order to apply the paste to a circuit board for printing, accurate printing with excellent printed shapes is provided by allowing the squeegee to flexibly fit the circuit regardless of its slope, swell, or warp to achieve balanced printing at a low specified pressure. To accomplish this, squeegees (26a and 26b) are elevated by an air cylinder (27) that can be rotated at the longitudinal center of the squeegees (26a and 26b) and that cancels their weight, and are then pressed downward by air cylinders (35 and 36) located symmetrically about the center in order to press the top surface of a screen (23).Type: GrantFiled: November 6, 1998Date of Patent: August 22, 2000Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Ken Takahashi, Syoji Sato, Hiroaki Onishi, Koji Mitsushiro, Takao Naito

Patent number: 5740729Abstract: In a printing apparatus and method, printing material is printed on to-be-printed circuit boards in a predetermined pattern and a printing state of the material is inspected. The apparatus includes the following devices. A board supporting device has a rotary body supporting a plurality of board-fixed tables to which the boards are secured, and turns the rotary body together with the board-fixed tables intermittently at predetermined angular intervals so as to stop the board-fixed tables at each of a fixing, recognizing, printing, and inspecting position. A board feed device feeds the boards to the board-fixed tables arranged at the fixing position. A board discharge device discharges the boards from the board-fixed tables arranged at the fixing position. A recognizing device recognizes fixed positions of the boards relative to the board-fixed tables at the recognizing position. A printing device prints the printing material on the boards at the printing position.Type: GrantFiled: September 29, 1995Date of Patent: April 21, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Osamu Hikita, Syoji Sato, Toshinori Mimura, Kazue Okanoue, Youichi Nakamura

Patent number: 5234105Abstract: A package is used for keeping an electric circuit board with no electronic components provided thereon in an air-tight cavity thereof and for preventing from oxidation during the transportation to the process wherein the electronic components are mounted on the electric circuit board. The cavity is composed of the lower and upper sheet of gas-impermeable materials, which are bonded at the bonded area by the fusion bonding, adhesive agent or viscous agent. The cavity is kept in non-oxidizing atmosphere by filling inert gas or evacuating air therefrom. The lower and upper sheets are composed of single layer or multi-layers, which may be made of flexible material or rigid material. An electric circuit board accommodated in the cavity of the package is taken out by the device comprising a separation roller pair. The device weakens the bonding strength to enable easy pulling of the lower and upper sheets to unpackage the circuit board.Type: GrantFiled: November 24, 1992Date of Patent: August 10, 1993Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Syoji Sato, Yasuo Izumi, Kazumi Ishimoto, Yutaka Makino

Patent number: 5017131Abstract: An atmosphere furnace including a plurality of divided furnace units, work transfer devices connecting the adjacent divided furnace units and those for the divided furnace units at both ends of the furnace. Each transfer device includes a tubular connecting frame and a work transfer member housed therein and the work transfer member has a work housing space in it. The work transfer member is rotatable, receives at a first position the work from outside or from an adjacent divided furnace unit into its work housing space, and send it out of the furnace or pass it to the adjacent divided furnace unit at a second position. When the work transfer member is at a middle position between the first and the second positions, the work housing space thereof faces an inner surface of the connecting frame so as to be sealed against the both end openings of the frame.Type: GrantFiled: June 29, 1990Date of Patent: May 21, 1991Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Syoji Sato, Yutaka Makino, Kazumi Ishimoto, Yasuo Izumi

Patent number: 4412237Abstract: Disclosed is a semiconductor device having a large number of basic cells, wherein a plurality of basic cells arranged along rows of a semiconductor substrate form a basic cell array and a plurality of the basic cell arrays are arranged along columns of the substrate, and further including spaces formed between each adjoining column. Each basic cell is comprised of first and second P-channel MIS transistors and first and second N-channel MIS transistors. The gates of both the first P-channel and the first N-channel MIS transistors form a first single common gate, and the gates of both the second P-channel and the second N-channel MIS transistors form a second single common gate. The sources or the drains of both the first P-channel and the second P-channel MIS transistors form a first single common source or drain, and the sources or the drains of both the first N-channel and the second N-channel MIS transistors form a second single common source or drain.Type: GrantFiled: August 29, 1980Date of Patent: October 25, 1983Assignee: Fujitsu LimitedInventors: Nobutake Matsumura, Ryusuke Hoshikawa, Yoshihide Sugiura, Hiroaki Ichikawa, Syoji Sato
