摘要:
The present invention has an object of eliminating the holding pin trace of a composite-molding of the dichromatic molding by refilling with resin by the pushing pin and preventing the lateral-shift of the primary molding during the refilling. It is made possible to fill closed recess and cavity with resin through a communicating hole formed in the primary molding by the pushing pin. A primary cavity mold 11 and a secondary cavity mold 12 are juxtaposed at symmetrical positions of a fixed plate 1. Core molds 14 closing alternately with both thereof are juxtaposed on a rotary table 7 installed on a movable platen 4. Holding pins 15 of the primary molding 30 and a resin pushing pin 16 are installed in the core mold 14 in a way to appear and disappear in respect to a cavity. The primary molding 30 is held in contact with the surface of the secondary cavity mold by the holding pin 15. A pin hole 20 for refilling resin is formed to be opened on a surface of the core mold by retracting the pushing pin 16. A secondary cavity including the pin hole 20 is refilled with a different material resin by injection. The holding pin 15 is retracted and sunk in the surface of the cavity mold. The pushing pin 16 is moved forward to force the resin for refilling the pin hole 20 into the resin in the cavity. The regions not filled with resin due to the holding pin 15 are refilled up.
摘要:
An automobile fuel container material and container has good workability, corrosion resistance of internal and external surfaces and weldability. Excellent environmental adaptability arises from the material being free from the elution of harmful components such as lead and chromium(VI). The automobile fuel container material includes a steel sheet, 5 to 80 g/m2 zinc plating as a first layer on at least one side of the surface of the steel sheet, 10 g/m2 nickel plating as a second layer, and not more than 5 g/m2 of a post-treatment layer. The post-treatment layer forms by coating partially reduced chromic acid and a reducing organic compound or can be an electrolytic chromate film as a lower layer and a resin as an upper layer.

摘要:
An apparatus achieves an exposure control for getting an image with the best SN without a mechanical iris and an image processing which is good at the color-reappearance and the gradation property with a simple digital processing circuit. When the film image is read by the line sensor 14 which has an electric shutter function, the electric shutter, the film feeding speed and the analog amplifier 16 are controlled totally so as to obtain images with the best SN from high to low transmittance negatives. And, when the dot sequential R, G, B digital signals are processed digitally, the offset values and the gain volumes of the respective R, G, B are calculated based on the maximum value and the minimum value which are detected by the respective R, G, B digital signals, the calculated offset values of the respective R, G, B are added to the dot sequential R, G, B digital signals which are obtained during the re-scanning, and the calculated gain volumes of the respective R, G, B are multiplied by the offset dot-sequential R, G, B digital signals so as to adjust the white balance and the black balance.
