Title: Dynamic tracking head device
Inventor: AOTO TAKANORI
IPC: G11B5/53
Filed: 1994-07-15
Abstract: PURPOSE:To reduce the occurrence of cracks in a piezoelectric element plate of a bimorph and to enhance the durability by forming a prescribed curvature in a holder for the bimorph on the side of a head. CONSTITUTION:A video head 5 for reproducing a video signal recorded on a video tape is fixed to one end 4a of the bimorph 4 in a prescribed shape, while the other end 4b of this bimorph 4 is held by the holders 6a and 6b consisting of an insulating material between them. These holders 6a and 6b are formed with a curvature R on the side of the video head respectively. Thus, by providing the holders with the curvature R on the side of the video head 5 of the bimorph 4 respectively, stress to be generated in the bimorph 4, i.e., the piezoelectric element plate when it is extended, contracted and bent is dispersed, thus reducing cracks and flaws, etc., to be generated in this piezoelectric element plate and enhancing the durability.

Title: Dry etching method
Inventor: ARIKADO TSUNETOSHI
IPC: H01L21/3065
Filed: 1980-11-21
Abstract: PURPOSE: To completely remove chlorine remaining at an etched surface, by forming an etched pattern in the Al film of a transistor in a dry etching process using chlorine gas, and then irradiating laser beams to the etched part.  
     CONSTITUTION: A phosphorus silicide glass film 11 is accumulated on the whole surface of a field oxide film 12, a gate oxide film 13 and a gate electrode on a Si wafer 11. A photoresist film is applied to the glass film-formed Si wafer, and a contact hole-forming resist pattern is formed by an optical etching method. Thereafter, a contact hold 17 is formed by selective etching. An Al film 18 is accumulated on the etched surface, and then dry-etched with use of CCl 4  gas to form an Al distribution pattern. The pattern is subjected to radiation of laser beams in vacuo, to assuredly remove chlorine remaining at the etched surface of the Al film. Consequently, the distribution composed of the Al film is not corroded or down due to absorption of water by chlorine.

Title: Input circuit
Inventor: SUZUKI SHINICHI
IPC: H03K19/003
Filed: 1984-08-06
Abstract: PURPOSE:To attain low power consumption by providing a switching means intermitting a current flowing a pull-up (or pull-down) resistor and latch circuit so as to decrease the current flowing to the resistor without increasing its resistance value. CONSTITUTION:An MOSFET transistor (TR) applies switching control to a current flowing to the pull-up resistor R in response to a pulse phi0 from a timing signal generator 15. The latch circuit 14 latches the potential fed to an input terminal 11 when the FETTR is turned on. Thus, the effective value of the current consumption IR by the pull-up of the input terminal 11 corresponds to the period and width of the pulse phi0. Thus, the current flowing to the resistor R is decreased without increasing the resistance value to attain low power consumption. The above is applied similarly in case of pull-down.

Filed: 1988-06-30
Abstract: PURPOSE:To accurately inspect severely for a specific region by moving the coordinates of a visual field, and forming a pattern to be detected together with a region requested for severity based on the coordinates and a region not requested therefor. CONSTITUTION:A range to be inspected is obtained by the planar extension of a visual point on the line of a wiring pattern from a design data such as CAD, etc., and divided for the visual field of a camera. The central position of the visual field of the camera is determined by considering the balance between the range to be inspected and the divided visual field range, a region to become the mount (b) of an IC chip and a specific region such as a region to become a wire bonded part lare extracted from the visual fields, and the coordinates of the visual field and the specific region are obtained. A defect inspecting reference pattern is formed by the width of one pixel for a pattern element (g) of an interval (h) or less between specific pattern elements or the pattern elements or the interval (h) therebetween on the region except the specific region in each visual field, and the defect inspecting reference pattern is formed in width smaller than at least one pixel than the pattern element (g) or the interval (h) between the pattern elements, and both the patterns are eventually combined.

Title: Editing device
Inventor: ISHIGURO MAMORU
IPC: H04N5/7826
Filed: 1981-10-15
Abstract: PURPOSE:To enable the editing of a static picture in addition to the ordinary editing with an operation system equal to the ordinary editing, by providing a control routine for the static picture mode in addition to the ordinary mode and properly switching the control routine between the ordinary and static picture modes. CONSTITUTION:When the execution of editing starts, a comparison is carried out first between the data of a start point PIN and finish point POUT of editing which are fed into a player of the reproducing side. When these data are coincident with each other, it is decided that the execution of a static picture is designated. Then a VTR functioning as a player is stopped at the point PIN in a mode of reproduction, and at the same time the VTR functioning as a recorder is stopped at a preroll point and then set in a play mode. Then a tape is driven up to a cut-in point to perform the editing of the static picture. If the data are not coincident between the points PIN and POUT, it is decided an ordinary static picture is not obtained. Thus an ordinary editing mode is set.

Title: Electromagnetic flow meter energizing circuit
Inventor: FUKUNAGA MASAO
IPC: G01F1/60
Filed: 1983-09-09
Abstract: PURPOSE:To prevent an overcurrent due to short circuit of an energizing circuit by providing a comparing and amplifying part for setting a current control part to a cut-off state, when an excess current flows to the energizing circuit. CONSTITUTION:In case a coil 4 is short-circuited, an overvoltage is generated across a current detecting part 5, and compared with a set voltage of an overcurrent setting part 12. In case an input overvoltage value is larger than the set voltage, an output of a comparing and amplifying part 7 is inverted, and a pulse signal for maintaining an H level for a prescribed time is outputted from a pulse generating part 8. During that time, a voltage which is larger enough than the set voltage of a current setting part 6 is applied continuously to an input of a comparing and amplifying part 3, therefore, a current control part 2 maintains a cut-off state, and an energizing current of an energizing coil 4 becomes zero. In this way, an overcurrent caused by short circuit of an energizing circuit can be prevented.
