Title: Magnetic sensor and its production
Inventor: TODA YASUSHI
IPC: G01D5/18
Filed: 1982-07-16
Abstract: PURPOSE:To save the labor of connection of lead terminals to prevent the occurrence of connection defects, by molding a chip in a case and grinding the end face on the side of a magnetoresistance element and the end face on the side of a leading-out electrode thereafter and forming a connection terminal by mask vapor-deposition or the like. CONSTITUTION:After a substrate (the chip) where an MR element 11 and electrode parts 12 and 12 are formed is molded in a case 14, and an end face 44 on the side of the MR element and a terminal taking-out face 43 on the opposite side of the case 14 are ground by a both-face grinder or the like to finish these end faces into specular faces. Connection terminal 31 having a C-shaped or channel-shaped pattern are formed by mask vapor-deposition or sputtering so that these terminals 31 are connected to electrode parts 12 on the terminal taking-out face 43, thus obtaining a magnetic sensor. Since connection terminals are connected by vacuum deposition or sputtering, the MR element is prevented from being degraded by heat or the like, and connection defects due to the wire bonding system or the soldering system are not generated.

Abstract: PURPOSE:To manufacture a high-performance heat reflecting glass having excellent weatherability, by applying a thin film of a metal having high infrared reflection in the form of being sandwiched between a pair of thin films of a specific metal oxide, to a substrate such as glass. CONSTITUTION:A substrate plate such as glass is cleaned, put into a vacuum chamber, and heated at 100-150 deg.C while evacuating the vacuum chamber. A mixture of argon and oxygen having an oxygen concentration of 5-30% is introduced into the vacuum chamber, and a thin Bi2O3 film having a thickness of about 400Angstrom  is deposited to the glass substrate by the reactive sputtering process using metallic Bi as the target. A thin film of Au or Ag, etc. of 50- 300Angstrom  thick is formed to the surface of the Bi2O3 thin film by using a metal t arget such as Au, Ag etc. while keeping the atmosphere of the vacuum chamber unchanged, and the metallic film is coated with a Bi2O3 thin film. The produced reflecting glass has high transmittance of visible light, high reflection to IR radiation or the light having longer wavelength than IR radiation, and excellent surface weatherability.

Title: Switching power circuit
Inventor: TANIGUCHI AKIRA
IPC: H02M3/155
Filed: 1990-05-15
Abstract: PURPOSE:To produce an output voltage without employing a transformer or the like, i.e., a source of electromagnetic noise, by producing a voltage through switching operation, cutting off DC component through a capacitor and then subjecting to rectification and smoothing operation. CONSTITUTION:A switching power circuit comprises an oscillation circuit 2 oscillating with a preset frequency to produce first and second square waves, a capacitor 5 for coupling transistors 3, 4, a full-wave rectifying circuit 6, and a smoothing capacitor 7 for feeding power to a load 9. The oscillation circuit 2 produced first and second square waves for alternately turning the transistors 3, 4 ON/OFF thus converting the source voltage into a pulse voltage. The capacitor 5 cuts off DC component in the pulse voltage to produce an AC voltage having amplitude half that of the source voltage which is then full-wave rectified and smoothed to produce an output voltage. Consequently, an output voltage can be produced from the source voltage with high conversion rate without requiring an inductance or a transformer.
