摘要： An object is to alleviate the concentration of an electric field in a semiconductor device. A gate electrode and a drain electrode are provided not to overlap with each other, and an electric-field control electrode is provided between the gate electrode and the drain electrode over a top surface. Insulating layers are provided between the gate electrode and a semiconductor layer and between the electric-field control electrode and the semiconductor layer, and the insulating layer provided between the electric-field control electrode and the semiconductor layer has a larger thickness than the insulating layer provided between the gate electrode and the semiconductor layer. Further, when the semiconductor device is driven, the potential of the electric-field control electrode may be higher than or equal to a source potential and lower than a gate potential, and for example, connection between the electric-field control electrode and the source potential enables such a structure.

摘要： It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.

摘要： A working machine includes: a first electric motor used for work; a second electric motor used for applications other than work; a first inverter circuit connected to the first electric motor; a second inverter circuit connected to the second electric motor; a battery connected to the first and second inverter circuits; and a control unit that drives the first and second inverter circuits. The control unit has a discharge mode to discharge electric power stored in the battery, and discharges the battery by stopping the first inverter circuit while driving the second inverter circuit in order to make the second electric motor perform electric operation in the discharge mode. Accordingly, since the state of charge is reduced, the life of a capacitor can be increased.

摘要： The present invention can be applied to a CMOS image sensor in which each pixel circuit of an active pixel sensor array includes a photoelectric conversion element for converting input light into electricity and a switch transistor for controlling the supply of a reset voltage for resetting the photoelectric conversion element to a predetermined voltage, to the photoelectric conversion element. The CMOS image sensor comprises a control circuit for assigning a control signal applied to a control electrode of the switch transistor. The control circuit outputs a first voltage much higher than a supply voltage of the CMOS image sensor so as to make an ON resistance of the switch transistor sufficiently small in the first part of a reset period of the photoelectric conversion element and outputs a second voltage lower than a supply voltage of the CMOS image sensor in the latter part of a reset period of the photoelectric conversion element.
