Abstract: A method for manufacturing a spiral tube which is made of a resin material and spirally covers a periphery of a wire harness along an extending direction of the wire harness, the method includes extrusion molding a tube material which is made of the resin material, heating and softening the tube material and forming the spiral tube, and spirally wounding the spiral tube around the wire harness and cutting the spiral tube.

Abstract: Sterilization or bacteriostasis is carried out using cellulose acetate. The cellulose acetate exhibits an excellent antibacterial property with respect to fungi such as Trichophyton, etc. and bacteria such as, for example, enteropathogenic Escherichia coli O-157 or Methicillin tolerance Staphylococcus aureus. The cellulose acetate may be mixed with resin such as, for example, polyethylene or polypropylene, and this mixture may be used to produce fibers. Then, a textile product may be manufactured using the fibers thus produced. The cellulose acetate may be dissolved in a mixed solvent of ethyl acetate, ethanol, and methyl alcohol, so that a coating material is prepared. This coating material is applied to an object to be sterilized and then is dried to form a coating film made of cellulose acetate. This coating film exhibits the antibacterial property.

Abstract: A door-checker harness is provided, by which a grommet is not needed, a wiring harness at the door-side can be simply and securely connected to a wiring harness at the vehicle body-side, and the wiring harness is protected from the outside. The door-checker harness includes a door-checker bar, one end of which is pivotally supported by a door-facing side of a vehicle body while an opposite end of which is inserted through an empty space of the door so as to regulate the maximum opening ratio of the door, wherein the door-checker bar is formed to be a cylinder having open both ends and circuit conductors for electrically connecting a harness at the vehicle body-side to a harness at the door-side are arranged inside the door-checker bar. The one end of the door-checker bar is inserted in a through hole at the door-facing side.

Abstract: A door hinge harness between a vehicle body and a door of the vehicle body is provided, which includes: a door hinge 1 to pivotally-supports a body side hinge portion 2 and a door side hinge portion 3 through an pin member for openably and closably attaching the door 8 to the vehicle body 4; and a circuit conductor W arranged through the door hinge for connecting a body side circuit 17 to a door side circuit 20, wherein the pin member is tubularly formed, and the door hinge harness 57 is arranged in an inner space of the pin member. An input side connector 19 for a connector 18 of the body side circuit and an output side connector 22 for a connector 21 of the door side circuit are provided on the circuit conductor W arranged through the inner space of the pin member. The input side connector 19 is attached to the body side hinge portion 2, and the output side connector 22 is attached to the door side hinge portion 3.

Abstract: A shear die is axially divided into a pair of die portions 18,19 between which a holding cavity 22 is formed, wherein the holding cavity has a diameter that is less than that of material "a" so that when one of the die portions is forced against the other die portion under a biasing effect of a spring 25, the material will be firmly held in the die cavity ensuring that the material can be cut to a predetermined volume and present a smooth cut surface, and the cutter arbor 4 is provided with a releasing member 34 adapted to release the one die portion 19 from the effect of the spring 25 as the cutter arbor 4 is retracted to facilitate additional material being moved into the die cavity for a subsequent cutting operation.

Abstract: A silicon carbide member is manufactured by depositing a silicon carbide coating on a substrate of silicon carbide containing free silicon by chemical vapor deposition. By gradually reducing the content of free silicon of the coating such that the coating is made of silicon carbide containing free silicon at the interface with the substrate, but of silicon carbide containing no free silicon at the outer surface, the coating is firmly bonded to the substrate, undergoes little thermal stress and is resistant against cracking and separation upon thermal cycling. The member is suitable for use in the heat treatment of semiconductor elements.

Abstract: An inner tube for use in a semiconductor diffusion furnace is provided comprising a liner or diffusion tube and an insulating layer formed on the entire outer surface of the tube by spraying, typically plasma spraying. The sprayed insulating layer is resistant to deterioration and peeling, ensuring an extended period of service for the tube.

Abstract: Disclosed is a silicon carbide type diffusion tube comprising a diffusion tube base made of reaction-sintered silicon carbide having an iron concentration of 20 ppm or below and a density of 3.0 g/cm.sup.3 or over, and a silicon carbide layer consisting of a high-purity silicon carbide film having an iron concentration of 5 ppm or below deposited on the inner surface of the tube base and a silicon carbide type diffusion tube comprising a diffusion tube base made of reaction-sintered silicon carbide, and a silicon carbide layer consisting of a Si-depleted layer formed in the inner wall of the reaction-sintered silicon carbide tube base and a high-purity silicon carbide film deposited on the Si-depleted layer, said silicon carbide film having a thickness of more than 0.5 mm.

Abstract: A slip prevention mat for vehicle tires which comprises a net-like structure having a rhombic lattice, said net-like structure being made of a rope provided with a cover layer, said cover layer being made of a natural or synthetic resinous material, first connecting means connected to one side of said net-like structure, for securing the net-like structure together at a position on the inside of the tire and second connecting means connected to the other side of said net-like structure for securing the net-like structure together at a position on the outside of the tire.
