  • Patent number: 7602921
    Abstract: The present invention relates to a sound image localizing apparatus for generating a sound image localized in an arbitrarily set three-dimensional direction. The sound image direction setting unit (111) is operable to set a three-dimensional direction to which the sound image is to be localized in accordance with a listener's instruction; the angle conversion unit (112) is operable to convert the direction into a lateral angle (?) and a rising angle (?), each of which serves as a cue for the listener to perceive the direction. The convolution operation unit 116 is operable to obtain lateral angle control information corresponding to the lateral angle (?) from the lateral angle control information storage unit (113), a listener's front direction head-related impulse response from the front direction head-related impulse response storage unit (115), and rising angle difference information corresponding to the rising angle (?) from the rising angle difference information storage unit (114).

  • Patent number: 7586091
    Abstract: After a sample is previously separated into plural components in a channel formed in a microchip (353), the channel is irradiated along a separation direction with a laser beam from a laser oscillator (361) to sequentially ionize each fraction separated in the channel. The ionized fraction is detected by a mass spectrometry unit (363) and analyzed by an analytical result analyzing unit (371). The analytical result is stored in a memory (369) while associated with position information in a driver control unit (367) and information on laser beam irradiation condition in a laser control unit (373), and the analytical result is imaged by an imaging unit (375). The imaged analytical result is displayed on a display (377).

  • Patent number: 7431503
    Abstract: A slider is displaceable in an axial direction on guide sections of a cylinder tube. Bearings are installed with the slider, so that the bearings are opposed to the guide sections. Bearings are also installed on first and second bearing support members, which are provided respectively at retaining sections of the slider. When the slider is displaced in the axial direction along the cylinder tube, only one end surface of one of the flange sections of the bearing is pressed, depending on the displacement direction of the slider, in order to effect displacement in an integrated manner.

  • Patent number: 7274016
    Abstract: A liquid sample (104) introduced in a main flow passage (101) is held in a dam portion (105), and a trigger liquid (106) is filled in a trigger flow passage (102). In this state, the trigger liquid (106) is further introduced at desired timing into the trigger flow passage (102) so that the front end portion of the level of the trigger liquid (106) is advanced and the front end portion is brought to be into contact with the dam portion (105). This causes the liquid sample (104) to move to the right (downstream side) in the figure, resulting in the liquid sample (104) flowing out to the downstream side of the main flow passage (101). This means that the trigger liquid (106) provides priming to realize a liquid switch.
