Title: Piezoelectric vibrator
Inventor: ARIMURA HIROYUKI
IPC: H03H9/19
Filed: 1988-06-17
Abstract: PURPOSE:To reduce the vibration level of sub vibration due to a waveguide and to prevent the change of the circuit constant due to an exciting electrode pair by forming an auxiliary path independently of an exciting electrode electrically in a direction propagating the sub vibration from a resonance area part and selecting the width of each area as a specific relation. CONSTITUTION:The auxiliary line 7 independently electrically of the exciting electrode 2 is formed from the resonance area part 4 in a direction of propagating the sub vibration. Then the width (a) of a leadout electrode 3 is selected to be 0.5w or below and the sum (a+b) of the widths of the leadout electrode 3 within the width of the resonance area part 4 and the auxiliary line 7 is selected larger than 0.5w. where (w) is the width of the resonance area part 4, (a) is the width of the leadout electrode connecting to the exciting electrode 2 and (b) is the width of the auxiliary line 7. Thus, the vibration level of the sub vibration is reduced by the waveguide path and the change of the circuit constant by the exciting electrode pair 2 is prevented.

Title: Ink sheet
Inventor: MURAKAMI SADATOSHI
IPC: B41J31/00
Filed: 1986-06-27
Abstract: PURPOSE:To obtain an ink sheet having excellent feedability and printing performance, by incorporating a solid electrolyte into an ink layer. CONSTITUTION:An ink layer 3A of an ink sheet 1A comprises a solid electrolyte having excellent electrical conductivity and transparency. The solid electrolyte may be, for example, an alkali metal salt such as lithium perchlorate, lithium phosphate and lithium silicate, and it is suitable that the content of the solid electrolyte in the ink layer 3A is 0.1-30wt%, from the viewpoints of antistatic property, printing performance or the like. Since the solid electrolyte incorporated in the ink layer has excellent electrical conductivity and transparency, the electrical insulating property of the ink layer can be lowered without adversely affecting the hue or the like of the ink layer. Accordingly, static electricity is prevented from being generated on the ink sheet, and the ink sheet is prevented from being rolled or tucked up around a platen, a pinch roller or the like due to electrification.

Title: Light circuit element
Inventor: KONDOU MITSUKAZU
IPC: G02B6/122
Filed: 1979-11-20
Abstract: PURPOSE:To miniaturize an element and to facilitate connections while reducing a loss of radiation of light at a curved line part by forming the substrate surface contacting with a curved-line light directing path lower than that contacting with a directional photocoupler. CONSTITUTION:The light circuit device includes directional photocouplers 3 and 6 made of two light directing paths closely formed by adding impurities near the surface of substrate 1, and curved light directing paths 2 and 4, and 5 and 7. Since this element has the substrate on the flanks of light directing paths at parts of curved light directing paths 2 and 4, and 5 and 7, an equivalent change in refractive index increases extremely in the surface direction of substrate 1, and consequently a loss of light radiation into substrate 1 at the curved parts can be reduced low enough to ignore it.

     CONSTITUTION: A superhard alloy part 1 is placed on a base 4, an iron-based sintered part 2 is placed through an infiltration material piece 32 on the part 1, and then an infiltration material piece 31 is placed on the parts 2. In this case, the infiltration material piece 31 having a lower melting point than that of the infiltration material piece 32 is used. And, they are infiltrated and braized at a given temperature in a furnace of an inert gas, whereupon the infiltration material piece 31 is first melted and imbibed into the inside voids of the part 2 until filled up and then the infiltration material piece 32 is melted. Since, even when part of the infiltration material piece 32 is absorbed in to the part 2, its most part takes part in braizing action in interface between the part 1 and the part 2, good infiltration and good braizing property can be attained.

Title: Manufacture of semiconductor device wiring board
Inventor: OTAKI HIROKO
IPC: H01L23/50
Filed: 1994-07-01
Abstract: PURPOSE:To prevent air from intruding into an adhesive sheet or between the sheet and a wiring board by a method wherein the adhesive sheet formed with slits formed into a roughly radial form is used. CONSTITUTION:An adhesive sheet 12 processed into a radial form is stuck on an island 13 of a lead frame. As the sheet 12 is formed into the radial form, the air between a wiring board and the island 13 is easy to bleed when the sheet 12 is bonded to the wiring board and the island 13 and does not remain between the board and the island 13. Moreover, in the case where gaps in the sheet 12 are provided, it makes easy to bleed the air that the gaps B on the periphery of the island 13 are kept being made larger than the gaps A closer to the center of the island 13. After such the adhesive sheet 12 is stuck on the island 13, the printed-wiring board is bonded to the sheet 12. Thereby, the lead frame never separates from the wiring board and moisture never stays between the lead frame and the wiring board. A highly reliable semiconductor device use wiring board can be obtained.

Title: Multilayer magnetic thin film
Inventor: ORIHARA HIDEJI
IPC: H01F10/00
Filed: 1981-09-24
Abstract: PURPOSE:To obtain a multilayer magnetic thin film and to prevent exfoliation of an electric insulating layer, by reducing the internal stress of the multilayer magnetic thin film consisting of a metallic ferromagnetic layer and the electric insulation layer. CONSTITUTION:After providing an active metallic layer 2 such as aluminum, chromium, titanium and silicon on a metallic ferromagnetic layer 1 such as ''Permalloy '', silicon steel, ''Sendust '' and ''Alperm '' by vapor deposition, the surface is naturally or compulsively oxidized to deposit and form a metallic oxide layer 2a having electric insulating property, and a metallic magnetic layer 3 of the same kind as the layer 1 is provided thereon.  As required, a multilayered magnetic thin film is formed with piles of many layers. Thus, since the internal stress due to temperature drop after the vapor-deposition is small between the layers 2a and 2b, the electric insulating layer is hardly exfoliated and the permeability can not be deteriorated at the ferromagnetic layer 1 side.

Abstract: PROBLEM TO BE SOLVED: To simultaneously measure many pieces, to shorten a time and to improve efficiency by parallel writing a nondefective code in all measurement devices, successively writing the nondefective code in its whole area of respective measurement devices and serially deciding whether or not respective areas of respective measurement devices are a nondefective area for all measurement devices. SOLUTION: The nondefective code is written simultaneously in addresses(ADD) Y of a device under test(DUT) in a test of a semiconductor memory(MGM) having nondefective component, and whether or not the test is advanced to a final ADD is decided. When the test is ended to the final ADD, whether or not the ADD of the DUT is the nondefective is decided, and when the nondefective area, the test is advanced to a next step, and when no, the nondefective code written in the control area of the ADD of the DUT is erased. Since the time parallel writing the nondefective code in all DUT is the same as the time writing it in a piece of DUT that all areas are nondefective, the time is shortened.
