Abstract: An X-ray tube which is high in brightness and high in resolution, and can withstand continuous long-time use, that is, it can withstand a high heat load. An X-ray target and an X-ray tube having the X-ray target include an X-ray generating metal layer having an average crystal grain diameter not larger than 30 &mgr;m on the surface of a base plate in the X-ray irradiated side. The X-ray tube has a small focus point and can withstand a high input load. A CT apparatus using the X-ray tube can provide a high resolution and a high definition image.

Abstract: A wig fitting implement which performs the fitting of a wig to a head surely and stably, can be put on and taken off easily, has no bad influence on the head like eczema and a rash, and has excellent workability is provided. A method of use of the wig fitting implement is also provided. The wig fitting implement 1 comprises a net-like base 2 divided into four regions. These regions correspond to a left side front surface (B side), a left side rear surface (D side), a right side front surface (A side) and a right side rear surface (C side). Double-sided tapes 3 (A1, B1, C1 and D1) and protective tapes 4 (A2, B2, C2 and D2) are adhered to each region. B1 of the B side is adhered to a surrounding rim part 13 of a flexible planar component 9 of a wig 7, and a natural hair 12 of a head skin 10 passes through penetration holes 6 and is held between C1 and B1 to fix the natural hair.

Abstract: A pickup apparatus which can easily pick up and pull out a thin plate member from a number of thin plate members disposed alongside one another in a narrowly spaced relationship and which assists in automating the picking up and pulling out of the thin plate member. The pickup apparatus includes a pair of pincer members which pick up and pull out the thin plate member from a number of the thin plate members disposed in a side-by-side spaced arrangement in a tray by expanding or contracting a bag member interposed between the pincer members to open or close the pincer members.

Abstract: A continuous hot dipping apparatus which comprises a slide bearing structure of a bearing and a roll shaft which is of a combination of a ceramic material and a solid lubricant material, and which has good wear resistance and long term durability. A heat resistant steel is provided, which is used in a molten metal of hot dipping and which essentially consists of 0.15-0.30% C, not more than 20% Si, not more than 2% Mn, 20-30% Cr, 10-20% Ni and not less than 50% Fe.

Abstract: The present invention deals with a method of taking out a substrate electrode of a LOCOS-type silicon gate MOSIC device from the surface of the semiconductor substrate. According to the present invention, a masking layer for preventing the introduction of impurities is formed on the periphery of the semiconductor substrate simultaneously with the masking step for forming a resistor of polycrystalline silicon, the mask is removed after the impurities have been introduced, and a substrate electrode is formed on the exposed surface of the semiconductor substrate.

Abstract: In a self-bondable insulated wire comprising a conductor and three resin insulating layers, the first resin insulating layer is formed with a resin selected from the group consisting of polyimide resins, polyamideimide resins and polyesterimide resins, the intermediate resin insulating layer is formed with a resin selected from the group consisting of polyvinyl formal resins and epoxy resins, and the outermost resin insulating layer is formed with a self-bondable resin of phenoxy series. Thus, a self-bondable insulated wire which is excellent in both oil resistance and heat resistance is obtained.
