Patent JP-H01209738-A (JP)
Title: Semiconductor manufacturing apparatus
Inventor: YAKUSHIJI HISAO
IPC: H01L21/68
Filed: 1988-02-18
Abstract: PURPOSE:To suppress dust that is attached to wafers to a large extent and to make it possible to obtain a high yield rate, by providing a ventilating fan at the lower part of a cassette stage where by wafers in a cassette are conveyed in and out by the up and down movement of the cassette. CONSTITUTION:More metal powder is yielded at driving screws 7 and other parts than friction parts 12. Since the metal powder comprises fine particles, the powder is floating for a long time. Unless the powder is removed quickly, the powder is attached at to a cassette 1 or wafers 2. For the purpose of removing the metal powder, downward streams 11 are generated with a ventilating fan 10a and vanes 10b which are arranged at the lower part of the cassette state. The yielded metal powder is exhausted. Thus, the yielding amount of the floating dust is decreased to a large extent. In this embodiment, an example wherein a bottom plate 14 of a mesh shaped device is used at a part directly beneath the fan at the bottom part of the apparatus is shown. When it is difficult to provide the mesh-shaped part at the bottom part, a duct 15 is provided so as to exhaust the dust to the outside.

Title: Cutting method for prepreg
Inventor: ABE NOBORU
IPC: B23K26/40
Filed: 1992-02-24
Abstract: PURPOSE:To exclude generation of resin powder, glass fiber powder and broken fiber from a cut surface, and prevent resin from adhering to a blade, by primarily cutting a resin part of prepreg with laser, without carbonizing said part, and secondarily cutting left glass fiber with laser. CONSTITUTION:Prepreg is resin-impregnated glass fiber base material in the B stage state of thermosetting resin wherein glass fiber base material is impregnated with resin and dried and semi-cured. When the above prepreg is further heated, the resin is fused and then cured. When the prepreg is cut by using laser, the prepreg is irradiated with the laser whose output is in the range that the resin of the prepreg is not carbonized which resin is impregnated in the glass fiber base material, and dried and semi-cured. Thereby the resin is fused and subjected to primary cutting. Left glass fiber is irradiated with laser whose output is increased. Thereby the glass fiber is fused and subjected to secondary cutting. By the cutting with two-stages laser, generation of resin powder or like can be prevented.

Since the magnetic flux 17 becomes excessively dense at the center and outside yokes 12, 11 proportionally to the segment width of the segments 10, the segment width of the segments 10 is finely formed, and the thicknesses of the center and outside yokes 12, 11 are reduced. A hollow bobbin 13 is inserted into the central yoke 12 is movable longitudinally without contacting with the segments 10 or the central  yoke 13, and a segment plate 14 is secured at 1/2 pitch of the segment width of  the permanent magnet at the bobbin 13.

Title: Production of high-purity 2,6-dimethylnaphthalene
Inventor: TAKAGAWA MINORU
IPC: C07C7/14
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To obtain 2,6-dimethylnaphthalene useful as a raw material for 2,6- naphthalenedicarboxylic acid by isomerization, crystallization and distillation of a dimethylnaphthalene mixture. SOLUTION: First, a dimethylnaphthalene mixture is isomerized in the presence of a catalyst (e.g. hydrogen-type mordenite) at 100-500 deg.C. Secondly, the isomerized product is crystallized in a solvent selected from aliphatic saturated hydrocarbons and alicyclic saturated hydrocarbons (e.g. heptane) to separate 2,6-dimethylnaphthalene. Thirdly, the mother liquor in the crystallization process is distilled to eliminate the components both higher and lower in boiling point than that of the dimethylnaphthalene, thus affording the objective dimethylnaphthalene fraction. Part or the whole of this fraction is circulated to the isomerization process.  By liquid phase oxidation of the 2,6- dimethylnaphthalene obtained above, dimethyl 2,6-naphthalenedicarboxylate or high-purity 2,6-naphthalenedicarboxylic acid each useful as e.g. a raw material for high-performance polyesters can be obtained advantageously.

Title: Thermal transfer material
Inventor: OHASHI MASATO
IPC: B41M5/382
Filed: 1987-02-20
Abstract: PURPOSE:To prevent foreign matter from being adhered to a thermal head even when recording is conducted for a long time and enable a thermal transfer material to endure preservation under hot and humid conditions, by providing a heat-resistant protective film of an aromatic polysulfone resin on the back side of a base film. CONSTITUTION:An aromatic polysulfone resin may be one represented by formula I. A polyester film is most preferred as a base because of its excellent heat resistance, mechanical strength, tensile strength and tensile stability. Though the base has higher thermal conductivity as it is thinner, a thickness of 3-50mum is most preferable from the viewpoints of strength and easiness of coating for providing an ink layer. For the ink layer, a conventional ink can be used as it is. An example of such ink is an ink prepared by using a wax such as paraffin wax, carnauba wax, Japan wax and bees wax as the binder and using a dye or a pigment as the coloring agent.
