Title: Manufacture of laminated ceramic capacitor
Inventor: HARADA AKIO
IPC: H01G4/30
Filed: 1987-09-01
Abstract: PURPOSE:To prevent the deterioration of quality in a plating process while improving reliability by providing a process, in which treatment is conducted by a coupling agent, between a process, in which an external electrode is applied to a tabular capacitor aggregate, and a process in which the external electrode is plated with a metal. CONSTITUTION:An internal-electrode leading-out section for a tabular capacitor aggregate in which a ceramic green sheet and an internal electrode (Ag-Pd, Pb, Ni, Cu, etc.) are laminated is dipped in the paste of Ag or an Ag alloy for an external electrode or the paste is applied to the internal-electrode leading- out section, and the paste is baked. A laminated ceramic capacitor acquired is treated with a coupling agent. Coupling treatment is conducted in such a manner that the baked laminated ceramic capacitor, on which the external electrode is applied, is dipped into the coupling agent (or a solution thereof), and is coupling-treated under decompression in a desiccator. The ceramic capacitor is taken out, and dried. It is preferable that such dipping and drying are performed twice or thrice. Electrolytic metallic plating (approximately pH4.5) by Ni or Cu or the like and electrolytic solder (or Sn, Pb) plating (<pH1-4.5) are conducted.

Inventor: YAMAMOTO TAKASHI
IPC: H03H3/02
Filed: 1982-12-14
Abstract: PURPOSE:To mass-produce small-sized piezoelectric oscillating parts which have uniform external appearances without forming any chips nor using any lead wire, by forming plural groups of electrodes on both surfaces of a mother piezoelectric substrate of a specific size and forming an oscillating electrode part, lead-out part, and external lead- out terminal part at every electrode. CONSTITUTION:Plural groups of electrodes 12 and 13 are arrayed on both surfaces of the mother piezoelectric substrate 11 opposed to each other through the substrate 11 placed in between, and the oscillating electrode part 14, lead-out part 15, and external lead-out terminal part 16 are formed for each group of electrodes 12 and 13. When adhesive layers 17 having an electric insulating property are formed on both surfaces of the substrate 11, spaces 18 and 19 are formed to prevent adhesives from sticking to the electrode part 14 and terminal part 16. Support plates 20 and 21 made of electric insulating materials are stacked on both surfaces of this substrate 11, pressed and heated to cure the adhesive layer 17, and cut into chip bodies 23. An external electrode 24 is formed on each conductive layer 22 of the exposed outer circumference part of each chip body 23, forming small-sized piezoelectric oscillating parts which have uniform external appearances.

Title: Wire binding tape-winding apparatus
Inventor: ARIMITSU FUJIO
IPC: B65B27/00
Filed: 1992-08-19
Abstract: PURPOSE:To constitute the apparatus into a very small size by giving a supply of a tape and rotation of a tape winding part selectively to a tape supply means and the tape winding part through rotating one motor forwardly and reversely. CONSTITUTION:When a motor 63 rotates in the direction R1 of forward rotation, pairs 57, 58 of rollers being tape supply means operate so that an adhesive tape 35 is supplied to the vicinity of a notch 66 being a wire receiving part. When the tape 35 is cut in this state by a cutter 88 and receiver edge 93 being cutting means so that a wire bundle is received in the notch 66, the wire bundle is bonded by the adhesive tape 35. When the motor 63 is rotated in this state in the direction of reverse rotation, the winding roller 67 of the tape winding part rotates without the supply of the tape 35. By the rotation of the tape winding part, the adhesive tape 35 is wound round the wire bundle so that temporary binding of a wire is achieved. Thus, it is possible to miniaturize the whole apparatus and therefore to position the apparatus also in a narrow place.

IPC: H01S5/00
Filed: 1991-08-30
Abstract: PURPOSE:To realize an optical integrated circuit in which an optical modulator is assembled as a low-chirping light source and a simple method for manufacturing the same. CONSTITUTION:A laser 13 an optical modulator 14 have a common active layer 1 (light absorption layer). Normally, the modulator is operated in a wavelength band in which an absorption coefficient at the time of no bias in an optical absorption layer becomes small. However, when the thickness of the absorption layer 1' is decreased to operate it with a high absorption coefficient. Further, the oscillation wavelength of the laser 13 is deviated to a longer wavelength side than the gain peak of the active layer to form the common active layer 1 (light absorption layer). Thus, a light source having high performance adapted for light transmitting at a high speed can be formed in a simple process. Particularly, an optical coupling between different type optical elements which normally becomes a problem, can be enhanced to provide large effects of enhancing the performance of an optical integrated circuit and simplifying the forming process of the circuit.
