  • Publication number: 20080316198
    Abstract: A portable phone has a main LCD and a SW-LCD, provided on a path of light to be transmitted by the main LCD, which electrically switches between (i) an image to be seen in a single image display mode and (ii) an image to be seen in a multiple image display mode. Furthermore, a first polarization plate serving as a reflective polarization plate is provided between the SW-LCD and the main LCD, and a second polarization plate is provided on a front surface side of the SW-LCD. The SW-LCD has a liquid crystal layer to which a voltage is applied in the multiple image display mode. With this, an image displayed by an image display can be seen from a front direction. In addition, the image displayed by the image display is blocked by the second polarization plate when the image is seen from the an oblique direction, and outside light from the oblique direction is reflected by the first polarization plate, so that a mirror surface display is carried out.

    Abstract: An optical beam emitted from a laser light source is converted by a spatial filter to have a desired beam diameter, and converted by a collimate lens into a collimated beam. The optical beam rendered to be a collimated beam has its intensity adjusted by an ND filter. The optical beam having its intensity adjusted is lead by a mirror to an angle rotation mirror. The angle rotation mirror reflects the optical beam toward a hologram element. Holograms are recorded on the hologram element in advance, so that reconstructed beams are collected at a prescribed position irrespective of an incident position of the optical beam.

  • Publication number: 20080307667
    Abstract: One type of dryer, namely a laundry dryer (1), comprises a water tank (20) and a drum (30). At the time of drying laundry, the interior of the drum (30) functions as a hermetically closed drying chamber (170). The air in the closed drying chamber (170) is sucked into a circulation duct (171) and heated by means of a heater (173) to a hot air before being blown into the closed drying chamber (170). The hot air having absorbed moisture from the laundry comes into contact with dehumidification water in a cooling chamber (174) within the circulation duct (171), thereby being dehumidified. The dehumidification water is sprayed by a mist generator (180). In the drying process, the mist generator (180) generates mist of metal ion water which has passed through an ion dissolving unit (100) and sprays the mist to the laundry.

  • Publication number: 20080308843
    Abstract: A GaN heterojunction FET has an AlxGa1-xN first graded layer and an AlyGa1-yN second graded layer, which are formed sequentially on a channel layer. The Al mole fraction x of the first graded layer decreases linearly from, for example, 0.2 at an interface of the first graded layer with the channel layer to 0.1 at an interface thereof with the second graded layer. The Al mole fraction y of the second graded layer increases from, for example, 0.1 at an interface of the second graded layer with the first graded layer to 0.35 at a surface located on the opposite side from the first graded layer. Because the intrinsic polarization of AlGaN depends on the Al mole fraction, fixed negative charge is generated in the AlxGa1-xN first graded layer, and fixed positive charge is generated in the AlyGa1-yN second graded layer.

  • Publication number: 20080311501
    Abstract: In a raw material mixing step, toner raw materials containing polymerizable monomers, colorant, and a release agent are mixed. In an emulsifying step, the mixture is emulsified under pressure to obtain a polymerizable composition. In a cooling step, the polymerizable composition is cooled down. In a depressurizing step, the polymerizable composition cooled down is depressurized. The polymerizable composition thus obtained has the colorant and the release agent evenly and finely dispersed therein. In a polymerizing step, the polymerizable composition is subjected to polymerization reaction. Toner particles are thus obtained which have uniform final sizes and exhibit a sharp particle size distribution.

  • Publication number: 20080313518
    Abstract: In a transmitter (2001), when generating a transmission frame having no limitation to a window size, a batch-transmission-end flag generating circuit (2004) and a sequence number generating circuit (2005) respectively adds a batch-transmission-end flag and a sequence number to the transmission frame. In a receiver, if an omission of a sequence number is detected as a result of analyzing sequence numbers of frames having received from the transmitter (2001), retransmission request is made when receiving a frame whose batch-transmission-end flag indicates the end. In this way, retransmission is possible in data transmission using UI frames, and the communication efficiency can be improved.
