Title: Electrode wire for wire cut discharge process
Inventor: INOUE KIYOSHI
IPC: B23H7/08
Filed: 1982-03-25
Abstract: PURPOSE:To prevent breakage of an electrode wire for electric discharge machining, by sticking an organic substance partially on the surface of said wire. CONSTITUTION:Organic substance is applied circularly on the surface of an electrode wire 1. It is thermally dissolved when passing a gap against a workpiece due to travelling of the electrode, thus to produce macromolecular carbon. Oxygen and hydrogen produced through decomposition of water fed at the discharge gap will react with said carbon thus to control the amount of oxygen and hydrogen existing at the processing section. Since the amount of hydrogen at the discharge section is controlled to be reduced, it will prevent the production of arc thus to prevent the explosion. While since the amount of gas existing in the gap is reduced through reaction with carbon, the foam to be adhered to the electrode wire is reduced thus to improve the cooling effect.

Inventor: ENDO HIROYUKI
IPC: C09K19/60
Filed: 1991-02-22
Abstract: PURPOSE:To obtain a liquid crystal which gives an element with high productivity, can easily be made to form a large surface area, and has a large tilt angle by mixing a ferroelectric high-molecular liquid crystal with a low-molecular liquid crystal and a dichroic coloring matter so that the tilt angle in the ferroelectric phase is above a specified value. CONSTITUTION:At least one ferroelectric high-molecular liquid crystal (e.g. of formula I) is mixed with at least one low-molecular liquid crystal (e.g. of formula II) and a dichroic coloring matter (e.g. an anthraquinone derivative) so that the tilt angle in the ferroelectric phase is 35 deg. or above, thus producing a ferroelectric high-molecular liquid crystal composition. To obtain the composition having a tilt angle of 35 deg. or above, it is desirable to use a high-molecular or low-molecular ferroelectric liquid crystal having a large tilt angle or a mixture thereof. By putting the obtained composition 5 between a pair of electrodes 6, 6, an optical element based on a guest-host liquid crystal, free from irregularity in color and having good contrast, can be produced.

Title: Bump and forming method of thereof
Inventor: KANESHIRO YOSHIO
IPC: H05K3/24
Filed: 1992-03-05
Abstract: PURPOSE:To provide a method of forming a bump adequate for COG-mounting a semiconductor chip on a circuit board. CONSTITUTION:A bump C is composed of a bump main body 4 of In, In-Ag alloy, or Pb-Sn alloy electrodeposited on a conductor circuit 2 or a semiconductor chip of a circuit board at a prescribed position and a bump sheath 5 of Cu, Au, Pd, Ag, Ni, or Pd-Ni alloy which covers the top or all the surface of the main body 4. Therefore, even if the formed bumps 4 are somewhat irregular in height, when the semiconductor chip 7 is mounted thereon and thermocompressed as a whole, as In, In-Ag alloy, or Pb-Sn alloy is low-melting material, the bumps 4 are softened at a temperature where a thermocompression process is carried out to be uniform in height. At this point, the bump sheath 5 envelops the bump main body 4 preventing the main body 4 from flowing out to an adjacent conductor circuit to cause a short circuit between the conductor circuits. A bump of this design can be useful for a liquid panel of high precision.
