  • Patent number: 9698569
    Abstract: To improve characteristics of a semiconductor device (semiconductor laser), an active layer waveguide (AWG) comprised of InP is formed over an exposed part of a surface of a substrate having an off angle ranging from 0.5° to 1.0° in a [1-1-1] direction from a (100) plane to extend in the [0-1-1] direction. A cover layer comprised of p-type InP is formed over the AWG with a V/III ratio of 2000 or more. Thereby, it is possible to obtain excellent multiple quantum wells (MQWs) by reducing a film thickness variation of the AWG. Moreover, the cover layer having side faces where a (0-11) plane almost perpendicular to a substrate surface mainly appears can be formed. A sectional shape of a lamination part of the cover layer and the AWG becomes an approximately rectangular shape. Therefore, an electrification region can be enlarged and it is possible to reduce a resistance of the semiconductor device.

  • Publication number: 20170171406
    Abstract: A touch panel has a display region for an operation screen and senses an outer object touching the display region. A vibrator unit applies vibration to the display region. In response to the touch panel sensing the object, a response controller unit instructs the vibrator unit to apply to the display region vibration responsive to the object. The response controller unit checks whether an image processing unit is under waiting or operating condition at the time the touch panel senses the object, and when the image processing unit is under the operating condition, sets the responsive vibration to a level lower than when the image processing unit is under the waiting condition.

  • Patent number: 9126453
    Abstract: In a wristbhaving a label-like structure, fracturing notches for preventing unauthorized use are positioned where the two ends of the band are to be glued together. If temporary peeling of the glued ends is attempted, the wristband breaks reliably and it is difficult to return it to the original state. If fracturing notches (11) are formed on either a first winding region (6) or a second winding region (7), which are positioned at left and right ends of the printing region (5). The wristband is configured so that a ring shape can be formed by overlapping and adhering the adhesive layer on the rear surface of one of shape, the first winding region (6) or the second winding region (7) onto the other winding region. An adhesion position check mark (15, 16) is formed on either the first winding region (6) or the second winding region (7).

  • Patent number: 8831457
    Abstract: A fixing device includes an excitation coil, a fixing member heated by electromagnetic induction by the excitation coil, a magnetic shunt alloy member, a Curie temperature of which is higher than a target fixing temperature, a determiner that determines whether the temperature of a non-sheet passing region of the fixing member is about to reach the Curie temperature, and a power controller that controls power supplied to the excitation coil. Until the determiner determines that the Curie temperature is about to be reached, the power controller performs feedback control to provide power to the excitation coil. When the determiner determines that the Curie temperature is about to be reached, the power controller switches to fixed power control so that a difference between power supplied when the Curie temperature is about to be reached and power supplied after reaching the Curie temperature falls within an allowable range.
