  • Patent number: 9254522
    Abstract: The mold clamping device is provided with a first platen to which a stationary mold is attached. A movable mold unit is capable of approaching and moving away from the stationary mold. A second platen is linked to the first platen via a tie bar. When the movable mold unit and the stationary mold are closed, a wedge member is driven onto the movable mold unit to generate mold clamping force. The second platen has a pressure receiving surface. The pressure receiving surface receives, through the wedge member, mold opening force that is generated by filling, with a molding material, the stationary mold and the movable mold unit that are in the closed state.

  • Patent number: 8897689
    Abstract: An image forming apparatus has an image forming information processor to process image forming information and an image forming unit to form an image on a recording medium by forming a toner image using colored-toner and a toner image using glossy toner based on the image forming information processed by the image forming information processor. The image forming unit forms a glossy image on the recording medium based on glossy toner image forming information, in which the glossy image is formable on the recording medium using the colored-toner toner image alone, or a glossy image is formed on the recording medium by forming a colored-toner toner image using colored-toner based on the colored-toner image forming information, and then forming the glossy toner image on the colored-toner toner image as a top layer of the glossy image based on the glossy toner image forming information.
