Title: Cylindrical iron core made of segmental pieces
Inventor: KURIHARA KEN
IPC: H01F3/02
Filed: 1981-02-28
Abstract: PURPOSE:To improve workability and space factor by forming a cylindrical iron core composed of many magnetic segmental pieces of wedge-shaped cross-section arranged in a circle which are welded together. CONSTITUTION:Magnetic segmental pieces 5 of wedge-shaped cross-section are put together in a circle so as to form a cylinder having a through hole 7 at its center. All magnetic segmental pieces are welded together at their inner upper and lower corners 6. Therefore, lines of magnetic induction can easily be through the center axis of the through hole and also at right angle to the center axis and, in addition, magnetic reluctance to alternating field in any direction can be reduced to a mimimum. Moreover, this construction facilitates machining for diameters and lengths of the work, and when a coil is wound on this iron core, the iron core and winding can concentrically be assembled with almost no gaps so that average length of coiled wires to a certain sectional area of an iron core an be mimimized so as to minimize a required amount of copper.

IPC: B23H7/10
Filed: 1988-02-10
Abstract: PURPOSE:To facilitate the succeeding wire connecting work by making the edge part of a wire electrode into straight form by correcting the curved form on a wire electrode which is curved and suspended from an upper nozzle because of breakage, by the jet stream of working liquid which is jetted downwardly from the upper nozzle part and carrying out cutting work. CONSTITUTION:When working liquid is jetted in the form of jet stream 37 downwardly from an upper nozzle part 15 onto a wire electrode 3 which is curved and suspended from the upper nozzle 15 because of the breakage due to short circuit, etc., the wire electrode 3 is set straight downward along the stream line of the jet stream 37. After the wire electrode 3 is clamped in this state by a clamper 35, the jet stream 37 of working liquid is stopped, and electric conduction is generated between the clamping part and the slidable contactor of the upper nozzle 15, and melting is executed. Then, the wire electrode 3 is set into straight state after cutting, and the succeeding wire connecting work is facilitated.

Title: Forming method of polyimide film
Inventor: MITSUI SHINJI
IPC: H01L21/30
Filed: 1992-02-18
Abstract: PURPOSE:To clean the surface of a pad, by exposing a semiconductor substrate wherein a polyimide pattern is formed and cured, to oxygen plasma. CONSTITUTION:Precursor (varnish) of photosensitive polyimide is spin-coated on a semiconductor substrate wherein a specified process is finished, and semi- cured. After the semi-cured polyimide film is irradiated with ultraviolet radiation and is optically crosslinked, development wherein solubility difference to solvent between the exposed part and the unexposed part is used is performed, and polyimide is cured by heating. Said film is exposed to an oxygen plasma atmosphere for a period capable of eliminating a reattaching layer of reaction product generated at the time of curing. Hence the reaction product which has reattached is oxidized and decomposed in the oxygen plasma atmosphere, and discharged to the outside of system, together with oxide of the reaction product and oxidation-modified material. Thereby the surface of a pad can be cleaned.

Title: Transmission type liquid crystal display device
Inventor: MARUYAMA MUNEO
IPC: G02F1/13357
Filed: 1994-02-28
Abstract: PURPOSE:To avoid visual angle dependence of a TN liquid crystal display device by using ah prism lens film and a wave lens film and to obtain good image quality with wide visual angle. CONSTITUTION:A loose directional characteristics A of a surface light source 1 is changed into a sharp directional characteristics B with a prism lens film 2. Further, by providing a louver on the front of the prism lens film 2, rays in the hatched region (b) in the figure can be wholly suppressed. Thus, almost parallel rays are made incident on the liquid crystal panel 11. The rays with good directivity which transmits through the liquid crystal panel 11 enters a wave lens film 9 and are scattered. Since rays with almost the same retardation are scattered by the wave lens film 9, the obtd. display gives a wide visual angle range without visual angle dependence. Since reflection of external light is prevented by a multilayer film 10, a good picture quality with high contrast can be obtd. without causing whitening of the screen.
