  • Publication number: 20140011372
    Abstract: A film deposition method deposits a silicon oxide film on a substrate in which a concave portion is formed by supplying a silicon-containing gas to the substrate so that the silicon-containing gas is adsorbed on the substrate and by oxidizing the adsorbed silicon-containing gas with an oxidation gas. A gas-phase temperature in an atmosphere above the substrate to which the silicon-containing gas is supplied can be kept lower by an inactive gas supplied from a separation area that separates the silicon gas supply part and the oxidation gas supply part even if the substrate is heated to a temperature higher than a temperature that can decompose the silicon-containing gas. Accordingly, the silicon-containing gas can adsorb on the substrate without decomposing in the gas phase.

  • Publication number: 20120271268
    Abstract: A compressed portion is formed in the absorbent article by compressing the absorber through a compression process. The compressed portion has a top-surface groove formed on the skin-contact-surface side, and a back-surface groove formed on the clothing-contact-surface side. A bottom portion of the top-surface groove is flat. Since the recessed portions are formed in the bottom portion of the back-surface groove through the compression process, a compression part where the density of the absorber is increased more than in an uncompressed portion and high compression parts where the density of the absorber is increased more than in the compression part are formed in the bottom portion. Thus, the absorbent article can be permeate into by a thick liquid, and is more likely to absorb liquid.

  • Patent number: 8256823
    Abstract: Core (16) in weatherstrip (13) is obtained by linking multiple core pieces (22) at given intervals to provide separation spaces (24) between individual core pieces (22). The interior of the separation spaces (24) is filled with filler polymer material (P2) having a thickness substantially equal to that of the core pieces (22). The whole surface of the core (16) is coated with the filler polymer material (P2). Accordingly, the thicknesses of trim polymer material (P1) at the area covering the core pieces (22) and at the area covering the separation spaces (24) are made substantially identical with each other, thereby attaining substantially zeroing of the variation of molding shrinkage along the thickness direction of the trim polymer material (P1).

  • Publication number: 20120123378
    Abstract: While a protection sheet 60 is disposed on a non-skin-surface 20a of an absorbent article 1, part of the protection sheet 60 is folded back in such a manner as to reach a position where the part overlaps other part, which comes in contact with the non-skin surface 20a of the absorbent article 1. An end portion 60a of the protection sheet 60 is bonded, while being folded back, to the protection sheet 60 by means of an adhesive material 70. Edge portions 60b and 60c on both sides of the protection sheet 60 in a longitudinal direction of the protection sheet 60 are bonded together through thermal fusion bonding while being folded. A second adhesive region 71 coated with the adhesive material 70 is formed in a predetermined position which faces the non-skin-surface 20a of a backsheet 20. The second adhesive region 71 is formed at a position corresponding to a non-adhesive region 52.

  • Patent number: 8123995
    Abstract: A molded product includes an already-formed member and an injection molded portion. The already-formed member, which has a joining surface, is placed in an injection molding mold, and the joining surface and the injection molding mold define a molding cavity. The injection molding mold further defines a spill cavity that is in communication with the molding cavity. Liquid molding material is injected into the molding cavity. At least some of initial molding material which has initially reached the joining surface flows into the spill cavity due to injection pressure of subsequent molding material injected after injection of the initial molding material, and is replaced with the subsequent molding material, which has a temperature higher than that of the initial molding material and a viscosity lower than that of the initial molding material.

  • Patent number: 8104227
    Abstract: A vehicle belt molding includes an attaching member and a seal lip. An elastic repulsive member is disposed between the engage wall portion and the seal lip and integrally provided with a fixed piece portion, a shifting piece portion, and a connecting piece portion. The seal lip is always urged toward the window pane by an elastic restoring force of the connecting piece portion itself or by a cooperative function of the elastic restoring force and an elastic restoring force of the elastic polymer material. When the attaching member is mounted to the mounting member, the seal lip causes the contacting portion to be elastically restored by the elastic restoring force toward a thickness direction of the window pane at a speed exceeding a restoring speed obtained only by the elastic polymer material.

  • Patent number: 8006437
    Abstract: A glass run channel assembly is provided. In the glass run channel assembly, after being mounted, an elastic force is generated in a vertical side portion which contacts a vertical frame of a door frame, and an elastic force is generated in an upper side portion which contacts an upper frame of the door frame. Here, the cross-sectional shapes of the upper side portion and the vertical side portion are adjusted such that the frictional force per unit length obtained by multiplying a coefficient of static friction of the upper side portion with the upper frame by the elastic force is larger than a frictional force per unit length obtained by multiplying the coefficient of static friction of the vertical side portion with the vertical frame by the elastic force.

  • Patent number: 7979972
    Abstract: A method for assembling a molding, including pre-assembling a molding by placing one of two inwardly bent longitudinal edges of a cover in a groove in a flexible main body, the groove receiving one of the two edges; placing the molding in a fixture so that the cover cannot be substantially flexed when a pushing force is applied to the molding; applying a pushing force to the main body of the molding, causing the main body to flex or compress under the pushing force; sliding the main body past the other of the two edges of the cover; seating the other of the two edges of the cover in another groove by releasing the pushing force allowing the main body to return toward an unflexed and uncompressed state inside the channel of the cover so the two parts form an assembled molding; and removing the assembled molding from the fixture.
