  • Patent number: 5704981
    Abstract: A partition member with a buffer plate disposed on the top surface thereof is disposed in a region belonging to a surface-to-be-processed of a substrate-to-be-processed held in a processing apparatus. An injector having cross-sectional areas decreasing toward the forward end thereof is disposed in the partition member. The injector has a number of injection holes formed length-wise therein at a constant pitch and in the same bore, whereby a processing gas can be injected very uniformly in the longitudinal direction and diffuse in the partition member. Then the processing gas is passed through vent holes formed in the buffer plate uniformly into the processing chamber. The processing gas can be fed uniformly onto the surface-to-be-processed of the substrate-to-be-processed, and a deposited thin film can have high intra-surface thickness uniformity.

  • Patent number: 5039298
    Abstract: A rotating shaft for intermittent rotation through predetermined angles is located in parallel to a rotation shaft of a rotor holding a plurality of split mold units, and rubber cups for adhering labels are secured to the front ends of links which are swingable about pins secured to the rotating shaft. The label is positioned upon the inner walls of the split mold halves when the same are in their open state by the combination of the intermittent rotation of the rotating shaft and the swinging movement of the links. The split mold holds the label by vacuum suction and the label is fused to a product when a highly heated plastic material is applied under pressure to the inner wall of the mold. A split mold holder is constructed so that when a slider-crank mechanism in association with a cam follower is positioned to a dead position, the clamping force is applied.
