  • Publication number: 20190165541
    Abstract: A laser element and a modulator element respectively include first and second mesa portions provided to be connected above a substrate. The first and second mesa portions are formed using individual mask films (dielectric masks). In the first mesa portion, a p-type first clad layer not containing Al as the uppermost layer thereof covers the upper surface and each of the side surfaces of a multi-layer body (including an n-type optical guide layer, an active layer, a p-type optical guide layer, and a p-type semiconductor layer). In the first mesa portion, the multi-layer body including the semiconductor layers containing Al is covered with the p-type first clad layer not containing Al. This can prevent unneeded aluminum oxide from being generated and improve the crystallinities of the constituent layers of the second mesa portion. It is possible to maintain excellent optical coupling between the first and second mesa portions.

  • Patent number: 10112314
    Abstract: A post-processing apparatus includes: a moving mechanism configured to move a punching apparatus in a width direction orthogonal to a transportation direction of a sheet; and a sensor configured to optically detect a mark formed on the sheet and indicating a position to be punched. The mark is configured such that an interval in the transportation direction between a plurality of feature portions extending in the width direction is configured to be changed depending on the width direction. The moving mechanism is configured to determine a position of the punching apparatus in the width direction based on a difference between respective timings of detection of the plurality of feature portions.

  • Patent number: 10069987
    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: 10020637
    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.

    Abstract: An image forming apparatus includes an acquiring unit configured to acquire atmosphere pressure in the installation place of the image forming apparatus, photoconductors, light sources configured to radiate laser light, and a polygon mirror configured to be rotatable. The polygon mirror exposes the photoconductors by reflecting the laser light toward the photoconductors while rotating. The image forming apparatus further includes a control device configured to control rotation of the polygon mirror. The control device outputs an enable signal for allowing the image forming apparatus to perform printing, if rotation of the polygon mirror is stabilized after start of the rotation, and advances the timing of outputting the enable signal as the atmosphere pressure increases.
