Title: Video display device
Inventor: IWATA YUKIHIRO
IPC: G09F9/313
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a frame chassis structure which satisfies both of falling strength and heat radiation characteristic by providing the reinforcing frames disposed on the rear surface of the frame chassis with vent holes and further improving the heat radiation characteristic by a method of arranging these vent holes. SOLUTION: The frame chassis 3 consists of the structure which is provided with the reinforcing frames 32 and 33 in a grid form so as to intersect orthogonally the respective sides of a display panel 1 on the rear surface and is provided with the vent holes at both of the reinforcing frames 32 and 33 at nearly equal intervals. The deflection of the display panel 1 induced by the falling impact during, for example, transportation, is suppressed and the damage of the display panel 1 can be avoided by such structure. In addition, the air heading above to below on the rear surface of the frame chassis 3 passes the vent holes 34 and 35 even in both of use of vertical placement and horizontal placement, thereby, a sufficient air flow rate may be obtained.  Cooling efficiency is, therefore, improved to suppress the temperature elevation of the display panel 1, and the damage of the display panel 1 occurring due to temperature elevation can be avoided.

Title: Motor drive controller for magnetic record reproducing unit
Inventor: KAWAGOE SEIJI
IPC: H02P8/32
Filed: 1989-10-31
Abstract: PURPOSE:To stabilize the motion of carriage in short time by generating a phase exciting signal for cancelling the vibration of the carriage in the seeking direction if no step pulse is received even upon elapse of predetermined step pulse interval. CONSTITUTION:A control circuit 13 judges that a carriage stopped if next step pulse/SP is not received even upon elapse of predetermined step pulse time interval, and generates a control pulse(phase exciting signal PH1) for cancelling the second and following peaks of vibration with a timing longer than the step pulse interval. The phase exciting pulse signal PH1 interferes with the original vibration wave to cancel the original vibration when the motion of the carriage stops. By such arrangement, motion of the carriage can be stabilized in short time.

IPC: G02F1/21
Filed: 1992-10-22
Abstract: PURPOSE:To stabilize characteristics of the optical waveguide device in a high frequency range, to enable low-voltage operation by the optical waveguide device and to reduce its size by specifying the arrangement position of a ground electrode in an asymmetrical strip line. CONSTITUTION:A signal electrode 30 has a pair of wiring parts 32 which are led out of both the ends of an electrode part 31 along an optical waveguide 20 in directions crossing the optical waveguide 20 and extended to one edge part of a substrate 10. The wiring part 42 of the ground electrode 40 wider than the wiring parts 32 is arranged on only one side including the outside of the curvature part of the electrode 30 opposite the wiring parts 32 at a certain interval so that the wiring part 42 is connected to the electrode part 40 of the electrode 40. Thus, the electrode 40 is made wider than the electrode 30, so a resonance phenomenon of size determined for a device chip is suppressed and a step in impedance connecting with a signal line is eliminated to make the impedance of the electrode 30 larger than when a coplanar strip line is employed.

IPC: G03F7/09
Filed: 1985-12-19
Abstract: PURPOSE:To form patterns on both sides of a substrate simultaneously with a photoresist by adding an ultraviolet absorber. CONSTITUTION:When a printed circuit board is produced, an insulating substrate is coated with a coating material contg. 0.1-5pts.wt., preferably 0.2-2pts.wt. ultraviolet absorber.

Filed: 1991-10-30
Abstract: PURPOSE:To form an anodic oxidation coating film as a composite coating film by dipping Ti (alloy) in a electrolytic bath in which the particulate of a tetrafluoroethylene resin is suspended and by applying voltage above sparking voltage. CONSTITUTION:The composite coating film is formed on the surface of Ti or Ti alloy by dipping Ti or Ti alloy in the electrolytic bath in which the particulates of the tetrafluoroethylene resin are suspended and by applying voltage above sparking voltage to anodic-oxidation treatment. In a forming process of the anodic oxidation coating film, the particulate 11 of tetrafluoroethylene resin suspended in the solution enters into a position, where heat is partially generated simultaneously with sparking, to weld. Since the particulate 11 of the tetrafluoroethylene resin is present in dispersed state in the coating film of the Ti anodic oxidation product or on the surface of the coating film, the wear resistance and contamination resistance of the composite coating film is improved.

Abstract: PURPOSE:To utilize effectively electric conductivity in the width direction of carbon fiber, and provide a porous electrode base material excellent in thickness directional electric conductivity by making carbonaceous milled fiber having a prescribed fiber length exist in the vertical direction to the surface of the electrode base material in a matrix part of the electrode base material. CONSTITUTION:Carbonaceous milled fiber is manufactured by pulverizing ordinary carbon fiber (containing graphite fiber), and though a fiber length is not more than 1.0mm, in this case, fiber not more than 0.1mm is particularly used. When the fiber length becomes longer than 0.1mm, inflow of a porous carbon fiber sheet-like material in the void is hindered. Here, resin solution or melting solution in which carbonaceous milled fiber having a fiber length of not more than 0.1mm and bulk density of 0.2 to 0.5g/cm<3> is mixed by a prescribed quantity is injected into the void of the carbon fiber sheet-like material of a porous structure.

Thereby, thickness directional electric conductivity of an electrode base material is improved.
