Publication number: 20030039106Abstract: A double-sided wiring board provides an electric connection between two wiring layers with the use of a recess, thereby improving a reliability on electric connection more than the related art, and a manufacture therefor. The double-sided wiring board (100) has a recess (106) blocked at the side of a first face (101a) and opened to a second face (101b) of an insulator (101). A laser light is irradiated to a blockage part (1061) of the recess (106), whereby a rough exposed face (1031) without a foreign matter (107) remaining is formed to a first conductive layer (108). A second wiring layer (105) is formed to be connected to the exposed face (1031) and electrically connected to the first conductive layer (108). The first conductive layer (108) and the second wiring layer (105) are more tightly connected than in the related art through the connection at the exposed face (1031). Reliability of the electric connection between the wiring layers is improved in comparison with the related art.Type: ApplicationFiled: September 19, 2002Publication date: February 27, 2003Inventors: Tatsunori Koyanagi, Yusuke Saito, Hideaki Yasui

Patent number: 6419540Abstract: A PDP does not suffer from dielectric breakdown though a dielectric layer is thin, with the problems of conventional PDPs, such as cracks appearing in the glass substrates during the production of the PDP being avoided. To do so, the surface of silver electrodes of the PDP is coated with a 0.1-10 &mgr;m layer of a metallic oxide, on whose surface OH groups exist, such as ZnO, ZrO2, MgO, TiO2, Al2O3, and Cr2O3. The metallic oxide layer is then coated with the dielectric layer. It is preferable to form the metallic oxide layer with the CVD method. The surface of a metallic electrode can be coated with a metallic oxide, which is then coated with a dielectric layer. The dielectric layer can be made of a metallic oxide with a vacuum process method or the plasma thermal spraying method. The dielectric layer formed on electrodes with the CVD method is remarkably thin and flawless.Type: GrantFiled: September 26, 2001Date of Patent: July 16, 2002Assignee: Mastushita Electric Industrial Co., Ltd.Inventors: Hiroyoshi Tanaka, Ryuichi Murai, Hideaki Yasui, Yoshiki Sasaki, Akira Shiokawa, Masatoshi Kudoh, Koichi Kotera, Masaki Aoki, Mitsuhiro Ohtani, Shigeo Suzuki, Kinzou Nonomura

Patent number: 5684574Abstract: A beam emitted from a light source including the characteristic wavelength of flown particles in a film forming system is interrupted by a beam chopper in a predetermined cycle, and is then divided into a probing beam and a reference beam by a beam divider. The probing beam passes through a particle flight area and is then injected into a photo detector through an optical filter, and a probing signal is outputted. A reference signal is obtained from the reference beam in the same manner. A data processor detects the phase and level of both signals, so that an absorbance, i.e., a film forming rate for the flown particles is estimated. The film forming rate is integrated with time so that a film thickness is estimated. Thus, the range of the applicable film forming rate is wide.Type: GrantFiled: October 31, 1995Date of Patent: November 4, 1997Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akira Shiokawa, Hideaki Yasui, Koichi Kotera, Yuuji Mukai, Hiroyoshi Tanaka, Takashi Hirao

Patent number: 5004264Abstract: A position control device includes a fluid-operated directional control valve for controlling the position of the piston of a cylinder assembly under fluid pressure in response to a control signal from an electronic controller. The position of the piston is predicted based on the control signal. A position detector detects when the piston has actually reached a predetermined position. When it is detected that the piston has actually reached the predetermined position, the predicted position of the piston is corrected. The electronic controller applies a control signal to the directional control valve so that the predicted position as corrected will be equalized to a target position for the piston. The predetermined position is a substantially intermediate position of the stroke of the piston. The directional control valve comprises a solenoid-controlled valve for controlling the flow rate of the fluid depending on the magnitude of a current supplied to the solenoid-operated valve.Type: GrantFiled: July 27, 1989Date of Patent: April 2, 1991Assignee: Nippondenso Co., Ltd.Inventors: Tetsuji Kozaki, Hiroshi Ishikawa, Hideaki Yasui, Mamoru Shimamoto, Katsuhiko Hibino, Motoshi Suzuki
