Title: Firing phase controlling method of ac/dc converter
Inventor: ISHIKAWA MASAHIRO
IPC: H02M1/08
Filed: 1984-05-22
Abstract: PURPOSE:To improve the transientvoltage responding characteristic of a firing phase control system of a firing pulse by executing the calculation of a control timing for next firing pulse by a forcible interrupt signal. CONSTITUTION:If next interrupt signal S is not generated within the prescribed period after an interrupt signal S synchronized with firing pulses Q1-Q6 is output, an interrupt signal B is output through an OR circuit 42 and an AND circuit 44 by the forcible interrupt signal E of the differentiator 50 of an interrupt signal generator 40, and this signal is supplied to a digital controller. Thus, if next firing pulse is not generated within the presecribed period after the interrupt signal synchronized with the pulses Q1-Q6 is out output, the signal E is generated to executed the calculation of a control timing for next firing pulse. Thus, even if the load of an AC/DC converter 10 varies, a phase control of the firing pulse followed by the variation in the load is performed.

Title: Sealing device for continuous vacuum treating device
Inventor: KITSUNAI HIROYUKI
IPC: B01J3/02
Filed: 1990-04-20
Abstract: PURPOSE:To obtain a high vacuum with a small-capacity pump and to make a treatment with high quality by pressing a mounted sheet material to each other under the surface pressure under which the sheet material does not rupture by means of members which are sealing means and constitute a narrow spacing only at the time of the initial discharge before the treatment. CONSTITUTION:Either one of the members 7, 8 constituting the spacing 6 is vertically moved and pressed to the other member under about the surface pressure under which the sheet material 3 does not rupture at the time of the initial discharge before the treatment. The inflow of the air between a preliminary chamber 4 and a treating chamber 1 is prevented in this way and the treating chamber is put into a good hermetic state. The treatment is executed by injecting a gas for treatment and the members 7, 8 forming the spacing are vertically moved to open the spacing 6 in such a manner that the sheet material 3 can be fed into and ejected out of the spacing. The continuous treatment is thus executed. The inflow of the air from the preliminary chamber 4 to the treating chamber 1 is prevented if the pressure of the preliminary chamber 4 adjacent to the treating chamber 1 is set at the pressure approximately equal to or slightly lower than the pressure in the treating chamber 1 after the introduction of the gas. The gaseous state in the treating chamber 1 is purely maintained at all times during the operation of the treating device.

Title: Production of preform and polymer optical fiber
Inventor: KOIKE YASUHIRO
IPC: G02B6/00
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To obviate the occurrence of scattering factors even if polymers of different kinds are used in producing a preform by a interfacial, gel polymn. method, etc., by forming a buffer layer on the inner peripheral surface of a hollow body. SOLUTION: The buffer layer B is formed on the inner peripheral surface of the hollow body D by using a resin material which has the same or nearly the same refractive index as the refractive index of the polymer by a monomer and is adjusted to the viscosity to the extent of not substantially dissolving the polymer of the hollow body D based on the fundamental that the monomer is polymerized within the hollow body D formed of the polymer. The polymn. of the monomer is effected within the hollow body D formed with the buffer layer B. Such buffer layer B imparts an interfacial gel effect to monomer polymerized in the hollow body D and prevents the dissolution of the polymer in the hollow body D, thereby functioning to prevent the occurrence of the scattering factors.

Abstract: PURPOSE:To prevent occurrence of a warp of a circuit board after curing and thereby to obtain a mounting structure of a semiconductor device of high reliability by a method wherein a sealing resin coating part having substantially the same extent with that of sealing resin around a semiconductor device disposed on the surface of the circuit board is provided on the reverse surface of the circuit board. CONSTITUTION:After a semiconductor device 3 mounted on a tape carrier is connected to a circuit board 1, sealing resin 5 is filled up around the semiconductor device 3 by using an injection tube or the like. With the circuit board 1 inverted thereafter, the sealing resin 5 is applied for coating by means of the injection tube or the like or printed on the reverse surface 8 of the circuit board in substantially the same extent with a resin-sealed area around the semiconductor device 3, so as to form a sealing resin coating part 10. When the sealing resin 5 is cured in this state, the sealing resin 5 on the surface 9 of the circuit board and the sealing resin 5 on the reverse surface 8 of the circuit board are cured simultaneously, and therefore shrinkage on curing which is concentrated only on one surface of the circuit board 1 is prevented. This enables prevention of occurrence of a warp due to the shrinkage on curing of the sealing resin, attainment of high reliability and thus attainment of a mounting structure of a semiconductor device being excellent in quality.

Abstract: PURPOSE:To successively execute a counting without simultaneously generating a loss time due to the change of a counted value by preparing a value to be automatically counted each time an overflow is executed and successively executing the counting. CONSTITUTION:At present, the value of a register A 3 is counted by a counter 1, when the overflow is generated to the counter 1, it is inputted through a detecting signal 11 to a control circuit 8.
