Title: Optical fiber splicer
Inventor: KUROSAWA YOSHINORI
IPC: G02B6/24
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To align and fix coated optical fiber and single optical fiber one by one by providing a first guide means for the insertion side of multiple optical fiber, guiding the coated optical fibers while being spread in the direction being away from each other, providing a second guide means in the insertion side of the single optical fiber end guiding the single optical fibers to the coated optical fiber. SOLUTION: The UV cured coated optical fibers 10 are inserted into a tape fiber insertion hole 23 is an arranged state. At that time, the fibers 10 are naturally separated when they are inputted to the respective coated optical fiber housing parts in a main body 2. Thus, the fibers 10 are away from each other by continuing insertion. Since the bending of the fiber 10 is gentle, insertion can smoothly be executed. A tape coating 8 is abutted on the trailing end of the coating storage part. When the respective single optical fibers 6 are inserted into single optical fiber insertion hole 24 one by one, bare fibers 11 are abutted on the bare fibers 13 of the fibers 10. A cap 26 is engaged into a cap hole 25 and the bare fibers 11 and 13 are pressed from above.

Title: Pulse train signal processing circuit
Inventor: MATSUI YOSHIHIRO
IPC: H02P5/00
Filed: 1991-07-10
Abstract: PURPOSE:To control increase of output pulse frequency by converting the 2-phase pulse train signal as an output of a rotary encoder to the corrected normal rotation pulse and the corrected reverse rotation pulse. CONSTITUTION:A difference between the number of normal rotation pulses 11 as an output of a 4-multiplying circuit 1 and the number of reverse rotation pulses 21 as an output of a pulse generator 6 is counted. A pulse generation permitting instruction 4 is issued to the pulse generator 6 so that the number of normal rotation pulses 11 as the output of 4-multiplying circuit 1 becomes equal to the number of corrected normal rotation pulses as the output of the pulse generator 6 and moreover the pulse generator 6 generates the corrected normal rotation pulse having constant duty ratio and period. Thereby, increase of frequency of output pulse resulting from phase difference of 2-phase pulse train signals output from the rotary encoder can be controlled to a value less than the predetermined constant value.

Title: Operating force transmission device
Inventor: SUZUKI KAZUHIRO
IPC: F16H61/36
Filed: 1987-07-08
Abstract: PURPOSE:To constitute the titled device so that it is sufficient that an inclination angle of an operating lever is small, by specifying a torque arm effective span between the connecting center to an oscillating arm on a torque arm and the fixing center of a conduit. CONSTITUTION:A torque arm effective span between the connecting center to an oscillating arm 9 on a torque arm 16 and the fixing center of a conduit is made smaller than an oscillating arm effective span between the oscillating center on the oscillating arm 9 and the connecting center to which the torque arm 16 has been connected. When an operating lever 1 is laid down to a prescribed angle, the oscillating arm 9 is also inclined to the same angle. Simultaneously, the torque arm 16 whose tip has been connected to the tip of the oscillating arm 9 is also inclined, but since the torque arm effective span is shorter than the oscillating arm effective span, a rotational angle of the torque arm 16 becomes larger, and since the conduit is fixed to the base end part of the torque arm, it is rotated larger than the inclination angle of the operating lever.

Title: Metallized organic film capacitor and manufacture thereof
Inventor: KAMIYA MICHIHARU
IPC: H01G4/32
Filed: 1989-06-30
Abstract: PURPOSE:To prevent a creeping discharge without lowering a breakdown strength characteristic of an organic film in a laser margin part which is formed when a laser margin is formed in a metallized organic film by laminating or winding the metallized organic film where paraffin composed mainly of a hydrocarbon having a specific melting point or softening point or of its derivative has been scattered at one part of a vapor-deposited film by using a laser beam and a peripheral part of an insulating groove has been formed. CONSTITUTION:A peripheral part of a part where a laser margin is formed is coated with a paraffin film 4; after that, a laser margin 3 is formed. A heat of fusion and a heat of vaporization of mainly a vapor-deposited metal when a laser beam scatters a vapor-deposited film are absorbed by a heat capacity, a heat of fusion and a heat of vaporization of the paraffin 4 itself in order to reduce thermal damage on an organic film to a minimum. As a result, even when a thin-film organic film is used, a through hole is not made in the laser margin. A gas layer does not exist near the laser margin and a creeping discharge is not caused. When the paraffin film is formed after the margin 3 has been formed or even when a hole is made in the margin part for some reason, a hole 7 is filled with the paraffin and the creeping discharge is not caused.
