摘要:
An optical semiconductor module including a housing (54), an optical semiconductor assembly (56), a movable ferrule (84), and a sleeve (60). The housing (54) has a hole (80) into which a connector ferrule (76) is inserted. The optical semiconductor assembly (56) is accommodated in the housing (54). An optical fiber (74,82) having a first end (82a) and a second end (82b) is fixed in the movable ferrule (84). The movable ferrule (84) has a thin hole (84a) in which the second end (82b) of the optical fiber (82) is inserted and fixed. The first end (82a) of the optical fiber (82) is supported so as to be optically coupled to the optical semiconductor assembly (36). The sleeve (60) is accommodated in the hole (80) of the housing (54), so as to align the movable ferrule (84) and the connector ferrule (76) with each other. The movable ferrule (84) is biased so as to be pressed against the connector ferrule (76) in the sleeve (60). With this configuration, even if an optical connector is repeatedly mounted/demounted with respect to the optical semiconductor module, a high efficiency of optical coupling between the optical connector and the optical semiconductor assembly (56) can be stably maintained, thus providing an optical semiconductor module having a high reliability.
摘要:
A receptacle optical module including a fixed housing adapted to be fixed to a mother board (substrate); an optical semiconductor assembly having an optical semiconductor chip for performing conversion between an optical signal and an electrical signal; a plurality of lead pins fixed to the fixed housing for mechanically fixing the fixed housing to the mother board and electrically connecting the optical semiconductor chip to the mother board; a movable housing pivotably provided on the fixed housing for supporting the optical semiconductor assembly; and a receptacle mechanism for detachably holding an optical connector in the movable housing so as to optically connect the optical semiconductor chip to the optical connector. With this configuration, the movable housing for supporting the optical semiconductor assembly is pivotably provided on the fixed housing, so that the optical connector can be easily attached/detached, and possible bending of the lead pins due to attachment/detachment of the optical connector is suppressed.

An optical module has a module case in which an optical device and a circuit unit electrically connected to the optical device are mounted. An optical connector of an optical fiber is detachably connected to the module case so as to be in contact with the optical device. The optical module includes a supporting structure supporting the optical device in a state in which the optical device is movable along a line, a force applying mechanism applying a force to the optical device in a direction parallel to the line along which the optical device is movable, and a locking mechanism releasably locking the optical connector pressing the optical device in a direction parallel to the line so as to be in close contact with the optical device, light passing through a boundary between the optical connector and the optical device.

An imprinting method carries out imprinting on a workpiece by clamping UV-curable resin between a nano-imprinting mold and a workpiece and curing the UV-curable resin using UV light. In this method, the workpiece is supported on a setting table provided with through-holes that are disposed in a planar region of the setting table on which the workpiece is set and are connected to a gas pumping/evacuating mechanism. The UV-curable resin is supplied onto the workpiece and the setting table is raised to and stopped at a filling operation position where the mold surface of the nano-imprinting mold and the surface of the workpiece are apart. After this, gas is pumped toward the lower surface of the workpiece from the through-holes and the workpiece is pressed onto the nano-imprinting mold from a center of the workpiece toward a periphery of the workpiece while gradually filling the UV-curable resin between the nano-imprinting mold and the workpiece. The UV-curable resin is cured by irradiating the UV-curable resin with UV light in a state where the workpiece is pressed onto the nano-imprinting mold by the pumping pressure of the gas.

The resin molding equipment comprises: a work piece feeding section; a work piece measuring section measuring thickness of a semiconductor chip mounted on a work piece; a resin supplying section supplying liquid resin to the work piece; a resin molding section having a molding die for molding the work piece with the liquid resin; a product measuring section measuring thickness of a resin molded part of the molded product; a product accommodating section; and a control section for controlling the sections. The control section includes means for adjusting an amount of the liquid resin, which is supplied to the work piece by the resin supplying section, on the basis of the thickness measured by the work piece measuring section.
摘要:
A luminance control device and method are disclosed. A surrounding brightness of a touch panel is measured to obtain a measured surrounding brightness. A luminance of the touch panel is controlled during a first time period starting from when the measured surrounding brightness changes from a first condition to a second condition, during which the measured surrounding brightness decreases by an amount equal to or greater than a threshold value. The luminance of the touch panel is maintained at a first luminance corresponding to the first condition when the measured surrounding brightness changes from the second condition to the first condition. The luminance of the touch panel is controlled to change to a second luminance corresponding to the second condition, when the measured surrounding brightness has not changed from the second condition to the first condition.

A coasting control device for reducing uneasiness experienced by a driver when pressing a clutch pedal during coasting control. The device includes a clutch control unit that, when the clutch pedal is pressed during coasting control, controls an actuator to cause an amount of hydraulic oil that depends on the amount of depression of the clutch pedal to be ejected from a clutch-free operating cylinder.

A coasting control device that prevents failures due to deterioration of a release bearing. The device includes an cumulative disengagement time measuring unit cumulatively measuring a duration of time that a clutch is being disengaged during coasting control, and an overtime restricting unit prohibiting coasting control when the measured cumulative clutch disengagement time has exceeded a predetermined time giving an indication of fatigue of a member of the clutch, and/or an overtime alarm unit providing an alarm when the measured cumulative clutch disengagement time has exceeded a predetermined time giving an indication of fatigue of the member of the clutch.
