A crusher includes a base, a cylinder pivoted to the base, cutting portions arranged on the cylinder. A crusher cutter assembly is further provided, including: a cutter base, for being assembled to the crusher, having receiving slots including an abutting recess and a bottom portion. A crusher cutter is further provided for assembling on the cutter base. The crusher cutter includes: two corner portions, disposed on two sides thereof, for being inserted in the abutting recess and fixed on the cutter base, two sides of the corner portion abutting against the abutting recess; two abutting portions, disposed on two opposite sides of the crusher cutter, for being positionably abutting against another crusher cutter; wherein when the crusher cutter is fixed on the cutter base, a part of the corner portion protrudes beyond the cutter base and is alternatively shifted with a part of the cutting portions.

A wind guiding cover, mounted on a fan, includes a rotating ring and a plurality of slats. The rotating ring is pivoted to the fan, and has an opening for an air flow generated by the fan to pass through. The rotating ring has a weight portion for offsetting the center of gravity of the rotating ring and normally maintaining the rotating ring at a static equilibrium position. The slats are pivoted to the rotating ring and arranged at the opening. When the fan operates, the slats are lifted by the air flow to open the opening. When the fan stops operating, the slats cover the opening under the gravity.

A system, client and method for transmitting preview message in an instant messaging system are disclosed by the present invention. And the system includes: a receiver (400) including a first preview message processing module (401), a first preview message display module (402) and a first receiving module (403); a sender (100) including a second preview message processing module (101) and a second sending module (104); an instant messaging server (200) for transmitting an instant customized message between the sender (100) and the receiver (400); and an Internet (300) for transmitting an instant message between the sender (100) and the receiver (400); wherein the second preview message processing module (101) is configured to convert the preview message received into a code, and transmit the code to the second sending module (104); the second sending module (104) is configured to send the code to the first receiving module (403) via the Internet (300); the first receiving module (403) is configured to send the code to the first preview message processing module (401); the first preview message processing module (401) is configured to convert the code into a prompt message indicating the preview message, and send the prompt message to the first preview message display module (402) for prompt.

A feed gas drying system is described for a PSA or VPSA oxygen concentrator. A membrane dryer is inserted into the feed gas path to the concentrator absorbent beds, such that the moisture in the feed gas is directed to a part of the dryer exposed to the concentrator exhaust, thus achieving efficient operation of the membrane dryer with no loss of concentrator feed gas.

The mode data of a block to be coded is predicted from the mode data of peripheral blocks already coded, and coded using a code word table switched according to a hitting ratio of prediction. In the code word table, the code word length is set shorter for coding modes with high hitting ratio.

The present invention relates to a wastebasket equipped with a roll vinyl pack. More specifically, for the purpose of simply and conveniently changing a roll vinyl pack installed in a wastebasket and maximizing the use of a space by preventing a space capable of storing garbage from being reduced because of the roll vinyl pack, the invention provides a wastebasket comprising: a body which has an upper end opened to accommodate garbage, and is formed with a space on an inner side thereof; a mounting unit which is formed on one side of the body, and is mounted with a roll vinyl pack; and a hook which is installed on the bottom surface of the body in order to guide a vinyl bag taken out of the roll vinyl pack so that the guided bag is unfolded on the body.
