Title: Pickup control device
Inventor: OTA FUMIO
IPC: G11B21/10
Filed: 1987-07-20
Abstract: PURPOSE:To reduce the disturbance of a control system even if a motor with cogging characteristics is used by giving a high frequency standing wave to a tracking servo system for a pickup. CONSTITUTION:The standing wave with a higher frequency than a servo band is impressed to a minus terminal of an amplifier 16 which is supplied to its plus terminal with a tracking servo amplifier output TAO via an LPF14 in the titled pickup device 10, and then a pickup driving motor 12 is driven with a servo voltage SLO which pulsates in synchronization with the cycle of the standing wave. When the voltage SLO is over the working voltage of the motor 12 by the excitation of this pulsating voltage, the motor 12 is immediately stopped, and even when the disturbance generates to the output TAO, the motor 12 does not unnecessarily rotate largely, thus suppressing the disturbance of the control system to be reduced.

IPC: H01L21/3205
Filed: 1992-07-08
Abstract: PURPOSE:To provide a semiconductor device which is capable of etching properly and forming a wiring layer at a fine span. CONSTITUTION:In terms of a semiconductor device having first wirings 1a, 1b, 1c and 1d oriented and laid out in one direction at a specified span on the surface of a semiconductor substrate, a second wiring 2 is installed on the substrate in such a fashion that the second wiring layer may keep a clearance from, and what is more, encircle the first wiring layers. This second wiring layer 2 has a projected part T projecting at the clearance portion so as to narrow the mutual clearance with the end portion of the first wirings. The projected part T, since it is designed to advance into the clearance portion when a plasma CVD film is mounted or etching is carried out, is protected from the formation of a void opening portion on a passivation film in a subseequent process or the generation of bubbles in a photoresist.

Title: Surface grinding method for fragile material
Inventor: CHIKAOKA YASUJI
IPC: B24B19/02
Filed: 1986-07-31
Abstract: PURPOSE:To prevent an angular part from generating a defect and to perform accurate surface grinding, by grinding a fragile material at a speed slower than the feed speed of grinding its plane part from a position, distant in an extension direction of a plane from the plane facing the angular part of the fragile material, toward a side of the plane. CONSTITUTION:When a work 2 of ceramics, which is a fragile material, is surface ground by a tool 1, it is fed to be transferred as shown by an arrow head D1 in the drawing from a condition A shown by a two-dot chain line, and the tool 1, when it is fed to be transferred to a point P1, grinds the work 2 changing a feed speed and a rotary speed faster. Next the tool 1, when it is fed to be transferred to a point P2, is once lifted to height B and moved to a condition C separating from the work 2, and the tool 1, which is again moved in the direction of an arrow head D4 by the grinding method similar to when the tool is fed as shown by the arrow head D1, moves in the direction of an arrow head D5 in a position slightly beyond the point P2, thus grinding is finished. In this way, the work of fragile material, which is ground in a speed slower than that in a plane part 4 from a position, distant from an angular part 3, toward the plane part 4, enables the angular part 3 to be prevented from generating a defect and accurate surface grinding to be performed.

Title: Video printer
Inventor: TSUJI JUNICHI
IPC: B41J2/00
Filed: 1988-07-20
Abstract: PURPOSE:To prevent the overlap of the adjacent edges of a plurality of exposure frames to be simultaneously exposed to light in an easy manner by mounting a light screening member on at least one edge of an image display plane of a CRT corresponding to the adjacent edges of the two or more frames to be simultaneously exposed to light by a cluster lens. CONSTITUTION:When a package photograph is to be formed on a sheet of color paper 15 by juxtapositioning two printed same images 40 in its feed direction, firstly a two-frame printing cluster lens 12 is set to a video printer. After the setting, a CRT 13 is driven to form the image, which is displayed on the CRT 13, on the color paper 15 through two image-forming lenses 10, 11. If the respective image-forming lenses 10, 11 of the cluster lends 12 has the dispersion of the focus distances or the failure in installation, which causes the edge parts adjacent to each other of the formed and printed images 40 to be overlapped, a rotating knob 37 is rotated. The rotation of the rotating knob 37 moves movable masks 30, 31 closely to each other, thus reducing the width of an exposure opening 32. In this manner, the overlap of the adjacent edges of two printed images 40 is prevented.

Abstract: PURPOSE:To eliminate a commutation failure by controlling a second power converter performing a natural commutation through the voltage of a high-frequency power supply so that said second power converter is slower than a first power converter in the control response speed of a power flow. CONSTITUTION:A high-frequency link converter is composed of a three-phase AC power supply SUP, an AC reactor Ls and first-second cycloconverters CC-1, CC-2 to drive an AC motor M. Also, a voltage control circuit AVR, current control circuits ACR1, ACR2, phase control circuits PHC1, PHC2, a speed control circuit SPC, etc., are used as control circuits. Then, said CC-1 and CC-2 perform a natural commutation by a high-frequency supply voltage, the CC-1 controls a power flow to be supplied so that the voltage peak value of a high-frequency power supply is made uniform, and the CC-2 controls a power flow to be supplied to an AC load, etc. Thus, when e.g., a stepped acceleration torque command is given, the CC-2 controls the rise of said power flow so that said rise takes a certain period of time, and said delay is set in such manner that said CC-2 is slower than the CC-1 in the control response speed.

The conductive part of the platen and the conductive part of the printing output part are electrically connected, thereby constituting an electric switch contact. When a gap length is to be detected, the printing output part is moved from a home position towards the platen. A distance from the home position to a touch position can be correctly detected by detecting that the conductive parts of the platen and printing output part are brought in touch with each other.
