  • Patent number: 7080712
    Abstract: An insulator dash (20) installed on the interior side surface side of a dash panel (10), comprising a single sound absorbing layer (21) formed of a fiber assembly or a laminated assembly having light and soft skin layers (22,23,26,27,28) laminated on the surface of sound absorbing layer (21), wherein, since the reflected noise reflected from the inner surface of an instrument panel (40) is taken again from the front surface side into the sound absorbing layer (21) for sound absorption in addition to the sound absorbing and shielding performance of the insulator dash (20), the sound absorbing performance in the instrument panel (40) can be increased, whereby the weight can be reduced and a rise of sound pressure in the instrument panel (40) can be abolishing a conventional sound shielding layer so as to increase a silentness in a cabin.

  • Publication number: 20050225595
    Abstract: A printer is disclosed for creating and cutting an image to be processed on a surface of an object. The printer comprises a guide rail that extends in a specified direction, an inkjet head supported on the guide rail for movement in the specified direction on the guide rail, wherein ink from the inkjet head ink is emitted and the image is created on the surface in response to image data, and a cutting head supported on the guide rail for movement along the specified direction on the guide rail for providing cutting of the image in response to the image data. A first driving means is provided for moving the inkjet head in the specified direction on the guide rail. A second driving means is provided for moving the cutting head in the specified direction on the guide rail. A controller provides control information to the first driving means and the second driving means.

  • Patent number: 6082981
    Abstract: An oil separator for a compressor according to the present invention is an oil separator (33) for separating oil flowing into a high-pressure chamber (21a) from a low-pressure chamber (21b) with a compression medium in a compressor from the compression medium, and comprises a demister (33a) which is in the form of a net formed by braiding metal thin wires and has surfaces subjected to sandblasting. Due to this structure, an oil separator for a compressor not reducing oil separability also in case of employing an HFC refrigerant and ether oil in combination with each other is implemented. The demister (33a) is formed by performing sandblasting on both front and rear surfaces of a netted strip (33a) and thereafter annularly winding the strip.

  • Patent number: 4979195
    Abstract: A vertical stepper transfers a circuit pattern formed on a mask onto a wafer using synchrotron radiation instead of a light source. The vertical stepper includes a wafer stage for having the wafer mounted thereon in the vertical direction and a mask stage for having the mask mounted thereon in the vertical direction. The wafer stage includes a coarse X-Y stage, a transfer member, and a wafer mounting member. The wafer mounting member is provided with a fine X-Y stage. The wafer mounting member is moved in the horizontal direction between a first position mounted on the coarse X-Y stage and a second position mounted on the mask stage by the transfer member. When exposed to the synchrotron radiation, the wafer mounting member is integrated with the mask stage. After the wafer and the mask are strictly correctly positioned by the fine X-Y stage, the wafer mounting member, integrated with the mask stage, is stepped and repeat exposed by scanning in the vertical direction.

  • Patent number: 3979220
    Abstract: Metal articles are sequentially treated in a surface-treatment tank containing a solution of surface-treating agents, then rinsed in a plurality of series-connected water-washing tanks.The contents of the surface-treatment tank and water-washing tanks are cycled to a concentrator by way of a heat exchanger and concentrated solution is returned to the surface-treatment tank. Steam is condensed in the heat exchanger to cause evaporation of water in the concentrator and the steam condensate is transferred to the water-washing tanks.
