  • Patent number: 8992209
    Abstract: Disclosed herein is an injection molding die used for producing a frame-mounted plate glass by injection molding. The die is characterized in that an auxiliary cavity is provided at a position to exposed a surface of a plate glass and communicated with a cavity for a frame through a communication opening, the cavity for the frame being provided at position facing a vehicle inside surface of the plate glass. When the die is practically used for injection molding, a load applied to a peripheral portion of the plate glass during the injection molding is reduced, so that when the frame is molded onto the plate glass by injection molding, undesired breakage of the plate glass is suppressed.

  • Patent number: 8162658
    Abstract: There is provided an injection die characterized in that the injection die is separated into at least two pieces, that a cavity for frame is formed between the separated dies, that the cavity for frame is provided with an additional cavity via a coupling hole, and that the coupling hole communicating with the additional cavity is provided at a confluence point of a resin in melted condition of the cavity for frame, at around a gate, at around a cavity for a fixing component, or at around a cavity for frame of which thickness is deep.

  • Publication number: 20110045123
    Abstract: In an injection molding die, there is defined a cavity for a frame or a cavity for the frame and an auxiliary cavity communicating with the cavity for the frame, and into the cavity for the frame or the auxiliary cavity, there is injected a melted resin from a runner through a gate, and a section of the gate has a width of 1 to 5 mm in the direction of a thickness of a plate glass and a width of 10 mm or more in the direction parallel with a side of the plate glass but smaller than a side length of the plate glass. When this die is practically used, a load that would be applied to a peripheral portion of the plate glass during injection molding is reduced, so that when the frame is integrally molded to the plate glass by injection molding, undesired breakage of the plate glass is suppressed.

  • Publication number: 20070030336
    Abstract: In a communication system for communicating a plurality of frequency signals between a first apparatus 1 and a second apparatus 2 via a common cable 3, a level loss component of each of the frequency signals in the cable is effectively corrected. Both transmission-sided reference frequency signal level detecting means 41 and 43 of the first apparatus, and reception-sided reference frequency signal level detecting means 71 and 73 of the second apparatus detect a level of a frequency signal which constitutes a reference among frequency signals which are transmitted from the first apparatus to the second apparatus via the cable.

  • Patent number: 7094375
    Abstract: A method for producing a window glass for a vehicle provided with an ornamental braid comprises steps of setting an ornamental braid on a lower mold of an injection molding machine, fixing an ornamental braid connection member on the lower mold, setting a glass plate on the lower mold, closing an upper mold, thereby locking the molds, and injecting molten resin into a cavity formed between the lower mold and the upper mold, thereby integrally molding a resin frame, the ornamental braid and the ornamental braid connection member along a periphery of the glass plate.
