Title: Manufacture of semiconductor device
Inventor: SOEJIMA KATSUMOTO
IPC: H01L27/06
Filed: 1986-04-11
Abstract: PURPOSE:To form minute an emitter and to obtain a bipolar transistor of high speed and high integration by removing an SiO2 film of the part which is to be an emitter of the bipolar transistor and depositing a second polysilicon and removing the polysilicon except for the part to be an emitter. CONSTITUTION:An SiO film which is to be an emitter of an N-P-N bipolar transistor Tr is removed by photoresist technique, thereby opening an emitter hole where an Si surface of a P-type base layer 10 is exposed. Next, a second polysilicon 17 is deposited and then the second polysilicon 17 is removed while leaving the second polysilicon 17 covering the emitter hole. By using A as a masking material 12 for ion implantation, arsenic ions are implanted. After removing the masking material 12, N<+> diffusion layer 11 and an emitter 20 of the N-P-N bipolar transistor Tr are formed by heat treatment.

Title: Manufacture of thick piezoelectric film
Inventor: SUMIMOTO MASATOMO
IPC: H01L41/45
Filed: 1990-03-30
Abstract: PURPOSE:To easily manufacture a thick piezoelectric film having high sintering density by adding metal alkoxide of precursor of a piezoelectric system to paste containing fine piezoelectric powder before or after a step of screen printing the paste on a board. CONSTITUTION:A pastelike thick film is formed of fine ceramic powder made of piezoelectric paste of mixture of lead titanate.zirconate as fine piezoelectric powder, metal alkoxide solution of its precursor, lead borosilicate glass fine powder as inorganic binder, ethylcellulose derivative as organic binder, and alpha-terpineol as organic solvent on an alumina board by a screen printing method, then the thick film is dried, further baked to form a piezoelectric thick film. Since the thick film having high sintering density can be formed by using the printing method, electric characteristics are improved without loss of the advantages of the printing, and even if electrodes are arranged on both upper and lower surfaces of the thick film, there is no fear of generating a short- circuiting state.

Title: Method of filling insulating oil into bushing pocket in transformer
Inventor: TAKEMOTO KAZUO
IPC: H01F27/14
Filed: 1982-05-17
Abstract: PURPOSE:To prevent the production of air bubbles in an insulating oil filled in a bushing pocket, by a method wherein the oil is filled, with the flow velocity thereof greatly reduced, so as to creep along a mounting seat and the wall surface of an insulating shield tube. CONSTITUTION:As an exhaust valve 18 and an oiling valve 15 are opened, an insulating oil flows into a bushing pocket 8 from a conservator 12 through an oil duct 16 and an oiling pipe 14. At the same time, the air inside the bushing pocket 8 is naturally discharged from the exhaust valve 18. The outflow of the insulating oil is suppressed by a narrow path constituted by the oiling pipe 14. In addition, the outlet side of the narrow path is opened in a trumpet-like shape. Therefore, the insulating oil is gradually decreased in flow velocity by flowing along the trumpet-like part, so that the oil flows while hardly producing air bubbles. The insulating oil flowing into an insulating shield tube 5 gradually increases in amount to fill the bushing pocket 8.

IPC: H04B10/2507
Filed: 1990-03-30
Abstract: PURPOSE:To simplify the fitting structure by providing magnets and 45 deg. Faraday rotators between laser diodes (LD) and a polarized light multiplexing film. CONSTITUTION:Laser diode (LD) modules 83 and 84 with polarized wave fibers are provided with the 45 deg. Faraday rotators 121 and 122 and magnets 131 and 132 between LD elements 101 and 102 and polarized wave fibers 3 and 4. The polarization direction of linear polarized light projected from the element 101 is rotated by 45 deg. through the rotator 121 to match the main axis direction of the fiber 3. This linear polarized light is reflected by the optical connector 9 of a single-mode fiber 5 and its reflected light is split by the polarized wave multiplexing film 1 into a P-polarized wave 6 and S-polarized wave 7. The P-polarized wave 6 which is transmitted through the multiplexing film 1 passes through a fiber 3 which the linear polarization is maintained, and is rotated by 45 deg. through the rotator 121 to become linear polarized light perpendicular to the linear polarized light projected from the element 101, so that the light returns to the element 101. Electric field components by the projection light and return light, however, cross each other at right angles in the element 101, so no noise is generated in the modulated light signal of the element 101. Fur ther, an S polarized wave 7 reflected by the multiplexing film 1 is similar.
