  • Patent number: 8334518
    Abstract: The invention presents a drinking water server having a configuration capable of suppressing generation of bacteria in a cold water tank, in a cold water pour tube, and in a pour valve. An opening part (2c) is formed in bottom side of a cold water tank (2), and a straight cold water pour tube (6) disposed horizontally in this opening part (2c) by way of a bent part (6b). An ultraviolet lamp (8) is disposed so as to reach up to a bottom part of the bent part (6b) by way of the opening part (2c) from inside of the cold water tank (2), so that ultraviolet rays emitted from the ultraviolet lamp (8) may be emitted uniformly both in the cold water tank (2) and in the duct of the cold water pour tube (6). As a valve body of a cold water pour valve (7), a diaphragm (71) for clogging the leading end of the cold water pour tube (6) is used, and dead angle of ultraviolet rays is eliminated.

  • Publication number: 20120237276
    Abstract: An image forming apparatus of the invention includes a carrier solution application roller that rotates centering on a rotary shaft and applies a carrier solution to a transfer roller after an image of a liquid developer including toner and the carrier solution is transferred to a transfer medium, a transfer roller cleaning roller, supported by a cleaning member support portion through a rotary shaft, which removes toner remaining in the transfer roller, and a carrier solution application roller of which the amount of movement is larger than the amount of movement of the transfer roller cleaning roller when the cleaning member support portion is rotated. Even when the transfer roller moves, satisfactory cleaning properties are secured without breaking a mutual positional relationship by facilitating mutual positioning between the transfer roller and the transfer roller cleaning roller.

  • Patent number: 7672619
    Abstract: A wire bar is formed by winding a wire, which comprises a first flat portion formed along an overall longitudinal length, around a peripheral surface of a metal core such that the peripheral surface of the metal core and the first flat portion tightly contact with each other. Since this increases the area size of a contact portion where the wire and the metal core contact each other, it is possible to increase the force of static friction which fixes the wire to the metal core. Fixing of the wound wire to the metal core by the strong force of static friction effectively prevents the wound wire from getting deviated.

  • Patent number: 7498902
    Abstract: A balanced/unbalanced filter module includes a switch including a first port that inputs and outputs unbalanced signals in a first frequency band, a second port that inputs and outputs unbalanced signals in a second frequency band, and a third port that inputs and outputs unbalanced signals in these two frequency bands. The switch switches a signal path. An unbalanced I/O port of a first filter that passes signals in the first frequency band is connected to the port. A port of a second filter that passes signals in the second frequency band is connected to the port. Individual balanced I/O ports of each of the first and second filters are connected to first and second branch ports with substantially the same electrical length. A balance coil for impedance matching is provided between the first and second branch ports.

  • Patent number: 7149459
    Abstract: An application roller comprises inclined sections which monotonously extend from central parts of peaks to the bottom of grooves. Hence, a liquid developer (a carrier liquid and toner particles) remaining on wall surfaces of the grooves of the application roller and the like without moving to a developer roller from the application roller, due to its own gravity, moves to the bottom of the grooves while applied upon the developer roller, and stays at inner bottom parts of the grooves. This effectively prevents air from getting trapped in the grooves during carrying of the liquid developer to the grooves, and hence, permits carrying of an appropriate amount of the liquid developer.
