Abstract: A manual pressing device for a flusher includes a stop ring, a pressing rod unit, a spring, and a nut. The manual-pressing device is located in a lateral hole of the body of a flusher, normally stopping water in the flusher or pressed to connect a lengthwise hole in the body with a water-exhausting passageway for flushing water. The nut screws with the body to keep the stop ring, the pressing rod unit and the spring stably combined in the lateral hole. When the pressing member of the pressing rod unit fitted with an outer end of the pressing rod is pressed inward, the annular leak recess of the pressing rod unit may communicate with the water exhausting passageway to let water flow therethrough so as to flush water, and releasing the pressing member pressed makes the pressing rod return to its original position to block the water exhausting passageway.

Abstract: A double valve flusher includes a body, a separating plate, an upper and a lower valve base, a movable valve, a film valve, a fixing member, and an electromagnet. An upper leak room is formed between the film valve and the upper valve base. A leak room is formed between the separating plate, the lower valve base and the movable valve contained in a chamber in the body. The upper leak passageway in the upper leak room and the upper valve base is blocked or opened by the core of the electromagnet, thus controlling the film valve in disfiguring to block or open the leak passageway of the leak room and the lower valve base. Then the movable valve is controlled to move up and down to flush or stop flushing water into a urinal where this flusher is positioned.

Abstract: The object of the present invention is to provide a wireless communication method and apparatus, which obtains both Multi-User Diversity (MUD) and Multi-User Multiplexing (MUM) effects simultaneously using multiple beams having random weights. In the wireless communication method, a transmission stage having M antennas (M is an integer equal to or greater than 1) selects B reception stages (B is an integer equal to or greater than 1) among K reception stages (K is an integer equal to or greater than 1) each having N antennas (N is an integer equal to or greater than 1) and generates B beams to transmit B signals in a multiple-access transmission manner. In the wireless communication method, the weight vector wb=[w1,b, w2,b, . . .

Abstract: A paper skew detection apparatus in an ink-jet printer. The paper skew detection apparatus includes a first light emitter positioned below the paper being transported to irradiate light onto the paper; a second light emitter spaced apart from the first light emitter a predetermined distance and positioned below the paper being transported to irradiate light onto the paper; and a detector positioned on one side of a carriage to receive light emitted by the first and second light emitters. Here, the carriage holds an ink cartridge, below which a print head to discharge ink is installed, and reciprocates rectilinearly in a direction orthogonal to a transport direction of the paper.

Abstract: A faucet with a connecting structure with a cold and a hot water pipe includes an inlet base formed in a lower portion. The inlet base has a lateral hole, a cold and a hot water passageway for receiving a cold and a hot water pipe therein and communicating with the lateral hole. A bolt extends pivotally in the lateral hole, having two convex faces to face or leave the water passageways to let two, cold and hot, water pipes to fit in the water passageways and then deadlocked or released by the bolt by means of the outer walls of the two convex faces of the bolt if the bolt is rotated forward or backward for a certain preset angle.

Abstract: A manual-automatic water faucet includes a shell installed inside with a water intake base, a water outlet valve, an electromagnetic valve, an induction device and a control device. The control device is composed of a valve rod, a spindle and a revolving button. The revolving button is able to actuate the valve rod to rotate or actuate the spindle to shift axially. When the valve rod is actuated to rotate, it can control water temperature, and when the spindle is actuated to shift axially, it can control the faucet to supply water automatically or manually.

Abstract: A manual and automatic flusher includes an infrared sensor added to a conventional manual flusher, and the infrared sensor consists of an electronic eye and an electro-magnetic valve. The electro-magnetic valve has an iron core moved in and out for controlling opening and shutting of a block, and a communicating tube connected between a flow hole of the block and the upper end of a valve body to enable a hand rod and the infrared sensor separately operated by means of the flexibility of the communicating tube, not interfering with each other. Then the flusher can be used by a manual operation or by automatic operation, with a simple structure for manufacturing.

Abstract: Disclosed is a fiber sheet having a heat-treated surface layer, comprising a polyester fiber applicable as heat insulating and sound absorbing materials. The fiber sheet is prepared by forming a surface layer at a particular level by continuously heat-treating a surface of the fiber sheet using 1 to 3 sets of hot press rollers at a post-process, where one set of the rollers consists of two rollers vertically arranged. Compared to the conventional products, the fiber sheet of the present invention has improved desurfacing property and bending strength, and good workability and interior property, as well as having improved texture, sound absorbing property and moisture resistance by regulating the size of surface pores.

Abstract: Disclosed is a refrigerator having a lower hinge member installed at a lower corner of a body forming a cooling compartment, and an upper hinge bracket installed at an upper corner of the body. The lower hinge member has a lower hinge pin assembled to a lower corner of a door for opening/closing the cooling compartment. A removable pin member is installed on the upper hinge bracket. The pin member has an upper hinge pin assembled to an upper corner of the door. A worker fixes the upper hinge bracket and the lower hinge member to the body, and then assembles the door to the body. Then, he installs the pin member on the upper hinge bracket, whereby the upper part of the door is assembled with the upper hinge pin. Thus, the door can be easily assembled to the body. Further, as the pin member is disassembled from the upper hinge bracket, the door can be disassembled from the body without detaching the upper hinge bracket.
