摘要： The light emission panel display device according to the present invention has a scan drive circuit (30) driving a selected scan line to a selected voltage and unselected scan lines to a non-selected voltage higher than the selected voltage in each scanning period and (3) a data drive circuit (20) supplying light-emitting drive current to the data lines respectively in the periods of light emission corresponding to display gradation. The data drive circuit (20) starts supply of the light-emitting drive current to the data lines respectively at the emission-initiation timing corresponding to the emission period in the scanning period, and terminates supply of the light-emitting drive current to the multiple data lines at the same emission-termination timing. In addition, the scan drive circuit (30) maintains the selected scan line to an emission-termination voltage higher than the selected voltage and terminates light emission of the light-emitting element connected to the selected scan line at the emission-terminating timing. It is thus possible to prevent continuous light emission of the light-emitting element emitting light by electrical charging and discharging at the emission-termination timing during light emission.

摘要： A method of manufacturing a stator coil for an electric rotating machine includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires through plastic deformation into a spiral or circular-arc shape; and (3) assembling the rolled electric wires together to form the stator coil. Further, in the rolling step, each of the planar electric wires is rolled by deforming each of the turn portions of the electric wire while restricting movement of at least one of the in-slot portions of the electric wire which is located closer to a rolling start end of the electric wire than the turn portion is.

摘要： A method of welding a plurality of conductors to form a winding extending through an annular stator core. The conductors are inserted into slots formed in the stator core to have coil ends extending outside an end surface of the stator core. A plurality of pairs of the coil ends are arranged in diagonal arrays extending diagonally with respect to a radial direction of the stator core. The method inserts a first electrode into a gap between adjacent two of the diagonal arrays and then brings a second electrode close to one of the adjacent two of the diagonal arrays to arc-weld, the pairs of the coil ends. This welding method enables the welding of the coil ends arrayed in the above layout efficiently while keeping the electrical insulation between the pairs of the coil ends.

摘要： A light source supplies optical signal to an optical switch and a detector detects light receiving level. A control unit changes a deflection control amount for changing an angle of a tilt mirror, and outputs the deflection control amount to a driving unit. When an input and an output ports are same, optical offset of the tilt mirror is calculated based on optimal angle at which the light detector detects an optimal point of the light receiving level. Whenever the input and the output port are different, a structure parameter of the tilt mirror is calculated based on the optical offset and the optimal angle. The optical offset and the structure parameter are stored in a memory as a test result.
