  • Patent number: 7192259
    Abstract: A variable capacity rotary compressor with upper and lower compression chambers having different capacities, the upper and lower compression chambers being partitioned from each other, and a rotary shaft extending through the upper and lower compression chambers. The rotary shaft includes a fixing hole and a latch pin which includes a head part is fixed to the rotary shaft through the fixing hole. The head part of the latch pin can be forcibly fit into a forcible fitting hole of the fixing hole. The head part is spaced apart from the inner circumference of the forcible fitting hole in the axial direction of the rotary shaft when the head part is forcibly fitted in the forcible fitting hole, so that a forcible fitting force is not applied in the axial direction of the rotary shaft.

  • Publication number: 20050286807
    Abstract: An expandable merchandising bag having an expansion section that permits a manufacturer to ship a product in the bag with the bag in a collapsed, smaller state, and a user to enlarge the bag via the expansion section to an expanded state. The expandable merchandising bag in the expanded state provides more ample room for receiving the product after used, thus providing the consumer with a reusable storage bag.
