Publication number: 20060066215Abstract: An upper bus electrode is formed as a laminated wire of a metal film lower layer, a metal film intermediate layer and a metal film upper layer. Al lower in electrode potential is used as a low resistance material for the metal film intermediate layer of the upper bus electrode, while Cr high in heat resistance and oxidation resistance and higher in electrode potential than Al is used for the metal film lower and upper layers disposed as upper and lower layers. Al and Cr are selectively etched so that the metal film lower layer projects on one side and has an undercut on the other side with respect to the metal film intermediate layer.Type: ApplicationFiled: September 30, 2005Publication date: March 30, 2006Inventors: Toshiaki Kusunoki, Masakazu Sagawa, Kazutaka Tsuji, Hiroshi Kikuchi, Yasushi Sano, Nobuyuki Ushifusa, Nobuhiko Fukuoka, Etsuko Nishimura, Takuya Takahashi

Publication number: 20040157174Abstract: In the apparatus for liquid preparation, the silver halide emulsion contained in a dedicated pot is transferred as liquid by a mohno pump via a piping into a measuring tank. The silver halide emulsion transferred into the measuring tank is measured with a load cell and is melted by heating with a jacket while being stirred by a stirrer. Accordingly, even when a small amount is used as in the case of the silver halide emulsion used in the heat-developable photosensitive material, the time for heating the silver halide emulsion, within the time range from the liquid preparation of the silver halide emulsion to its utilization, can be made short to the utmost, and hence the time elapse in melt can be suppressed. Thus, the time elapse in melt, reagent loss, and mutual contamination in the liquid preparation of photographic reagents can be effectively prevented.Type: ApplicationFiled: February 11, 2004Publication date: August 12, 2004Applicant: FUJI PHOTO FILM CO., LTD.Inventors: Yasushi Sano, Yoshitsugu Moizumi, Kazuaki Miyashita

Patent number: 6264097Abstract: This invention provides screen printing for forming a higher solder ball (bump). In first printing step, a first solder layer is printed. After drying in drying step, a second solder layer is printed on the first solder layer in second printing step. Then, in re-flow processing step, re-flow processing is performed, and the first solder layer and the second solder layer are melted. Finally, the melted layer is solidified in a ball shape to form the solder ball (bump). Since solder paste is printed in layers, an amount of the solder paste can be increased. Hence, a higher solder ball (bump) can be formed.Type: GrantFiled: June 19, 2000Date of Patent: July 24, 2001Assignee: Micro-Tec Company, Ltd.Inventor: Yasushi Sano

Patent number: 5699732Abstract: This invention is aimed at achieving a high-tension combination stretch screen. First, a print screen-mesh is bonded to a supporting screen-mesh at a bonding area. Then a portion of the supporting screen-mesh overlapping the print screen-mesh is removed. Then a new supporting screen-mesh is bonded to the bonding area, and again, a portion of the supporting screen-mesh overlapping the print screen-mesh is removed. Doubly fixed supporting screen meshes thus provide sufficiently increased tension to the print screen-mesh.Type: GrantFiled: August 28, 1995Date of Patent: December 23, 1997Assignee: Micro-Tec Company Ltd.Inventor: Yasushi Sano

Patent number: 5045942Abstract: In a digital video communication system, a network clock source is provided to supply a common clock pulse synchronized with the transmission speed of the system to each station through a transmission channel to allow it to derive a video sync pulse. This sync pulse is applied to a video signal source to generate an analog composite television signal. A quantization sampling pulse is derived from the video sync pulse which is contained in the composite television signal to quantize the composite television signal. The quantized video signal is stored in a buffer and forwarded to a receiver station in response to the received network clock pulse, so that the quantization sampling rate and the transmission sampling rate of a transmitter station of the system are synchronized with each other. The sampling rate of the dequantization process at the receiver station is also synchronized with the transmission sampling rate.Type: GrantFiled: November 17, 1988Date of Patent: September 3, 1991Assignee: NEC CorporationInventors: Shuzo Tsugane, Sadaharu Hiratsuka, Toshio Kawaji, Yasushi Sano

Patent number: 4616353Abstract: A tracking servo circuit corrects for closed loop gain variations due to wear of the disc, the width of the electrode of the reproducing stylus, etc. The disc contains an information track bounded by servo tracks used to derive a tracking error signal. This tracking error signal is supplied to an AGC circuit after being filtered and detected. The gain of the AGC circuit decreases as the voltage level of the tracking error signal increases. The tracking error is also supplied to an electric-mechanical conversion system after an oscillatory signal of constant frequency and amplitude is added to it. The oscillator signal is used to stabilize the gain of the servo loop. The electric-mechanical conversion system corrects the position of the stylus in response to these signals.Type: GrantFiled: April 13, 1984Date of Patent: October 7, 1986Assignee: Victor Company of Japan Ltd.Inventors: Isami Kaneda, Yasushi Sano
