  • Patent number: 7081799
    Abstract: There is provided a bipolar transistor that enables a desirably enhanced high-frequency performance to be obtained when used as an oscillation amplifier of an oscillation circuit, and that is miniaturized and reduced in cost. A capacitance adjustment line (11) connected to a base pad (7) forms a parasitic capacitor with respect to an N+ collector substrate by interposing an insulating film (3) and an N collector substrate therebetween, thereby increasing collector-base capacitance Ccb. This capacitor is incorporated into a bipolar transistor, which functions as an oscillation amplifier and has a small transistor operation region (2), at least as a part of a balance capacitor constituting the oscillation circuit in the course of production of a semiconductor.

  • Patent number: 7046309
    Abstract: There is provided a single panel type video display capable of increasing the luminance of image. A color separator separates light from a light source into light beams in three colors in a band shape to emit the light beams and introduces the band-shaped light beams in the three colors so as to be overlapped with one another in a predetermined region. A lens array wheel has a plurality of functional units each composed of a convex lens of a size corresponding to the predetermined region, circularly passes the plurality of functional units each composed of the convex lens through the predetermined region, and scrolls the band-shaped light beams in the three colors in a state where they are divided among regions on a single liquid crystal display panel. A video signal is fed to the liquid crystal display panel in synchronization with the movement of the plurality of functional units each composed of the convex lens.

  • Publication number: 20060096448
    Abstract: An apparatus for detecting the displacement of a movable member of an electronic musical instrument. The apparatus has superior mechanical durability compared to displacement sensors of the past and can withstand long-term use. The apparatus includes a sensor that provides a detectable electrical characteristic having a value and a spring that, when compressed upon displacement of the movable member acts with the sensor, causing the value of the electrical characteristic to change. The value of the electrical characteristic represents the amount of displacement of the movable member and is used by a controller of the electronic musical instrument.

  • Patent number: 7032692
    Abstract: Locking elements 3d and 3j are provided at an inner member 3 connected to a kelly bar 1, and a locking element bearing plate 6f is provided at an outer member 6. The outer member 6 includes a cylindrical bucket 7 and a grab bucket 8 housed inside the cylindrical bucket 7. When an excavating tool 2 is in its most contracted state, the inner member 3 is rotated forward to lock the locking elements 3d and 3j at the locking element bearing plate 6f, thereby disallowing relative vertical movement of the inner member 3 and the outer member 6. As the excavating tool is rotated by applying a force to the kelly bar 1 along the lifting direction in this state, an excavating operation can be executed while applying a load smaller than the load of the excavating tool 2.

  • Publication number: 20060050245
    Abstract: An optimal processing portion (21) inputs a video signal (RGB signals) and analyzes 1-frame video in the video signal. For example, if the intensity of red color is 0 percent in all dots in 1-frame video, the optimal processing portion (21) applies to a light source gain adjustment portion (22) a control signal for rendering a gain of the illuminating device (1R) 0 percent (minimum amount of light). The light source gain adjustment portion (22) receives the control signal and controls power supply to the illuminating device (1R). In addition, the optimal processing portion (21) applies a driving instruction for rendering the amount of light transmission 0 percent with regard to all dots of the liquid crystal display panel (3R), for example, to a LCD signal processing portion (23).
