IPC: B65D25/34
Filed: 1980-05-28
Abstract: PURPOSE: To obtain a welded part excellent in rust-inhibiting property at a low  cost, by forming the side seam part of a welded can body by a lap seam electric resistance welding method, and coating metal-exposed parts at the outside surface  and both sides of the welded part with an organic film.  
     CONSTITUTION: A welded can body 1 is provided with a welded part 2 formed by the lap seam electric resistance welding of its side seam part. Metal-exposed part 3 at the outside surface 2a and the both sides of the welded part 2 are coated with an organic film 4 containing a pigment or metal powder.

Title: Extrusion lamination of ethylene resin
Inventor: ISHIZAKI YOSHIHIRO
IPC: B29C47/04
Filed: 1988-03-24
Abstract: PURPOSE:To improve adhesive strength and heat-sealability with a base material and to prevent the occurrence of smell, by extruding an ethylene resin from a die of an extruder at a specific resin temp. to prepare a molten thin film, carrying out thereon an ozone treatment and press-bonding and laminating it on the base material where an anchor-coat treatment has been done. CONSTITUTION:A molten thin film is prepared by extruding an ethylene resin (except branched low density polyethylene) from a die of an extruder at the resin temp. of 150-290 deg.C. Then, an ozone treatment is carried out on this molten thin film. Then, this treated surface as the adhesive face is press-bonded and laminated on the base material where an anchor-coat treatment has been done. As the ethylene resin, medium density polyethylene, linear low density polyethylene and so on can be cited as the representative one and these resins are used by blending them mutually or with other resins and rubbers. It is preferable that the melt flow rate of the ethylene resin is 1-300 g/10 min. The ozone treatment is carried out by blowing a gas containing ozone on the molten thin film from a nozzle or a slit-like blowing port.

Title: Noise reduction device of chain transmission mechanism
Inventor: NAKASHIMA KUNIHIKO
IPC: F16H7/06
Filed: 1981-05-12
Abstract: PURPOSE:To improve the silencing effect by adjusting the natural frequency of the sprocket with the centripetal direction slits at the teeth bottom of the sprocket. CONSTITUTION:When the roller chain 2 is rolled into the sprocket 1, the link plates 2b and 2c touch the elastic ring 4 prior to the rotating roller collides with the teeth bottom 1b of the sprocket 1, then said roller chain 2 reduces its speed before it touches the teeth bottom 1b. Therefore, strong collision is avoided and the noise is reduced. Now, the sprocket 1 is provided with slits 5 on the teeth bottom 1b, by which natural frequency can be adjusted high or low to a certain extent. Therefore, since the natural frequency of the sprocket 1 can be adjusted to coincide with the frequency which is easy to be damped by the elastic ring 4, the device can efficiently be silenced.

Filed: 1984-04-09
Abstract: PURPOSE:To inexpensively perform positioning of an arm, by installing a stopper groove to the arm which can rock around a shaft independently from the shaft and rocking the arm by interposing a clutch mechanism between the shaft and arm and stopping the rocking motion by utilizing the stopper groove. CONSTITUTION:The driving force of a motor 1 is transmitted to a shaft 9 through gears 4 and 8 and a friction disk 18 and adapter plate 19 also move together with the shaft 9 under a united condition. The friction disk 18 is pressed against an arm 22 by a spring 20 and the arm 22 makes rotating motions around the shaft in the same direction as the shaft 9. The arm 22 stops the rotating motion when a cushion 24 comes to the end of a groove 22' installed to the arm 22. However, the motor 1 is still actuated and the arm 22 continues to receive the force in the same direction. Therefore, bounding, etc., at the arm stopping position never occurs.

Title: Color selecting method of color image display system
Inventor: TANAAMI YOSHIAKI
IPC: G09G5/06
Filed: 1993-03-30
Abstract: PURPOSE:To reproduce colors which are close to an original image by varying the number of divisions of a color space corresponding to an input image and then varying the size of a partial color space. CONSTITUTION:Which of (m) partial color spaces each pixel of input image data 27 is present in is calculated and the address (8 bits) of an entry of an LUT 22 wherein the representative color of the partial color space is set is written in the location of a frame memory 21 corresponding to the pixel. In the memory 21, display image data obtained by compressing 24-bit full color data to 8 bits are completed. Further, 8-bit data in the memory 21 are sent to the LUT 22 and the 24-bit representative color corresponding to the display pixel is outputted. Consequently, when the color distribution of the input image is concentrated on a narrow range, a maximum number of representative colors are obtained within the number of entries of the LUT 22, the number of divisions is automatically set to a large value to make the partial color space small, and consequently delicate differences in the colors of the input image can be reproduced.
