Title: Method and device for mounting part
Inventor: HANAMURA NAOKI
IPC: H05K13/04
Filed: 1991-08-22
Abstract: PURPOSE: To enable quicker mounting of a component by correcting the position of a component sucked by using a reference mark formed on a moving head. CONSTITUTION: When a component 2 is sucked by a nozzle 4 of a moving head 3 and moved over a camera, the position of the head 3 is detected by a position detecting sensor 11. A control means 10 outputs the positional information to an image-processing means 12 and a reference mark 8 and the component 2, sucked by the nozzle 4 are photographed at the timing of passage of the component above the camera 5. The obtained photographing information is inputted to the means 12. A relative position between the previously determined reference mark 8 and the nozzle 4 and the deviation of the sucked position of the component 2 from the detected reference mark 8 are calculated, and the deviation is outputted to the means 10.  The means 10 outputs a control signal to a drive means based on information outputted from the means 12, so that the position of the head 3 is adjusted to correct the deviation, and the component 2 is mounted on a prescribed position of a substrate 6.

Title: Vertical die casting machine
Inventor: ANAMI MASAHARU
IPC: B29C45/26
Filed: 1991-08-22
Abstract: PURPOSE:To easily and quickly execute changing work of die and to obtain a vertical die casting machine enabling manufacture of a product having little burr. CONSTITUTION:By preventing inclination of an upper platen 16 by a connecting rod 70, movable tie bars 28 are made to two pieces and the changing work of the die is facilitated. A pressing device composed of mainly a pressing cylinder 76 always presses the upper platen 16 to the stopper 84 by the fixed pressing force to prevent the inclination of upper platen 16. At the time of die-clamping, reaction force to the die clamping force by a die clamping cylinder 56 separates the upper platen 16 from the stopper 84 against the pressing force of pressing device. As the pressing force is low and the reaction force to the die clamping force is almost uniformly loaded to each tie bar 26, 28, the die clamping force is uniformly loaded to the die to obtain the good product having little burr.

Abstract: PURPOSE:To provide the title shielding member having resiliency to keep suffi cient air tightness and water tightness as well as high electromagnetic wave shielding capability by forming a member body with resin including elastoma and depositing a conductive film on a body surface. CONSTITUTION:A conductive film is formed on the surface of a body compris ing, as a raw material, resin such as elastomar as an electromagnetic wave shielding member. For materials of the conductive film there are available metals such as aluminum, titanium, and nickel or copper.

IPC: H01L21/3065
Filed: 1985-10-21
Abstract: PURPOSE:To perform an etching of excellent reproducibility having no residue by a method wherein, after a polycrystalline Si film has been etched by performing an anisotropic etching method using flon gas, an isotropic etching is subsequently performed in the same chamber using SF6 gas. CONSTITUTION:The residue 50 of the second layer of polycrystalline silicon 20 remains on the edge of the first layer of polycrystalline silicon film 40 in the semiconductor device whereon an anisotropic etching is performed with flon gas using a photosensitive resin film 10 as a mask. If said residue 50 is removed by performing an isotropic etching in the same chamber using SF6, a double layer polycrystalline silicon electrode structure can be obtained. A high etching rate of polycrystalline silicon can be obtained at low power in this isotropic etching, and as the ratio of etching rate between a polycrystalline silicon film and an oxide film becomes 30 or thereabout, the residue can be removed quickly almost performing no etching on the oxide film located under the polycrystalline silicon film. When a microscopic pattern is going to be formed, the polycrystalline silicon electrode can be formed quickly in an excellent reproducible manner without giving physical damages on the substrate surface and the like by performing the above-mentioned procedures.

CONSTITUTION:This composition comprises 4-carbamoyl-1-beta-D-ribofuranosyl- imidazolium-5-oleate as an active ingredient, an immunosuppressive agent named misoribine on the market, as an active ingredient. Steroid-resistant multiple myositis is a disease which has to require administration of a stetoid agent of >=40g/day at an early period of treatment, raises GOT, LDH and CPK as myogenetic escaped enzymes and ascertains myogenetic change by an electromyogram and inflammatory change in striated muscle by myogenetic examination. A dose is 1-10mg/kg calculated as used amount of misoribine per adult daily. In steroid therapy, grave side effects are taken into consideration and reduction in amount of steroid agent is required but misoribine has not rephrotoxicity, slight residue in blood and extremely small transmigration to brain.

Title: Production of structure transfer glass
Inventor: YOKOYAMA OSAMU
IPC: C03B19/12
Filed: 1988-09-21
Abstract: PURPOSE:To prevent engagement of a structure to be transferred according to a sol-gel method and obtain a formed body without cracking or breaking by specifically providing a part facing a part having the above-mentioned structure and part sandwiched therebetween. CONSTITUTION:A mold is constructed from the first part 11 having a formed structure 12 to be transferred, the second part 13 arranged facing thereto and the third part 14 sandwiched between the parts 11 and 13. The part 14 has a smaller section (14a) on the side of the part 11 than the cross section (14b) on the side of the part 13. A sol solution 15 is then cast into the mold and gelatinized to provide a gel shrinking the volume thereof as indicated by arrows 19. In the shrinking process, since stepped parts 18 due to a difference in the cross section of the part 14 are present, the gel 16 is supported by the stepped parts 18 and a structure 17 transferred to the gel is simultaneously separated from the mold 11. Thereby, the surface 17 of the gel having the transferred structure and the structure 12 of the mold 11 will neither mutually engage nor rub even if the shrinkage of the gel is present.

Filed: 1992-09-04
Abstract: PURPOSE:To obtain a positive characteristic thermister having excellent characteristics by performing burning while specifying the ratio between the mass of a positive characteristic thermister and the volume of burning sheath thereby preventing evaporation of lead oxide from the thermister. CONSTITUTION:Dy2O3, MnCO3 and SiO2 are admixed with temporarily burnt (Ba1-X-Y, MY, PbX)TiO3(0.03<=X<=0.7, 0<=Y<=0.2, and M is at least one of Ca or Sr) and then they are subjected to wet kneading. It is then dried, temporarily burnt, and pulverized through a ball mill. Powder material thus obtained is then added with a binder, i.e., polyvinyl alcohol, and granulated and then the granules are shaped into a disc thus obtaining a molded item of positive characteristic thermister. After setting the ratio between the mass of the molded item and the volume of burning sheath in the range of 0.2-1.20g/cm<3>, the molded item is burnt at 1200-1250 deg.C in the atmosphere. This method allows sintering without causing evaporation of constituent lead and lowers nominal zero load resistance while enhancing variation of resistance.
