摘要:
An electrode drive circuit performs interlaced scanning, ensuring that the phases of the sustaining pulse in odd-numbered lines and even-numbered lines among L1 to L8 between surface discharge electrodes are the reverse of each other. With this, when either odd-numbered lines or even-numbered lines are displayed, the voltages applied between the electrodes of the undisplayed lines are at 0, eliminating the necessity for partitioning walls on the surface discharge electrodes. In surface discharge electrodes, X electrodes are provided on the two sides of a Y electrode and the area between the Y electrode and the X electrode on one side is assigned a display line at an odd-numbered frame, and the area between the Y electrode and the X electrode on the other side is assigned a display line in an even-numbered frame. Alternate areas between the surface discharge electrodes are assigned as blind lines and a discharge light emission in the blind lines is blocked or incident light to the blind lines from the outside is absorbed. Address electrodes are provided for each monochromatic pixel column and selectively connected with the pads above them, performing simultaneous selection of lines.

Disclosed is a light-intensity modulation element, which comprises a substrate made of a nonlinear optical crystal, and a light waveguide formed in a principal surface of the substrate to extend in one direction. The light waveguide includes first and second wavelength conversion portions for converting a part of infrared light introduced into the light waveguide to a second harmonic. Each of the first and second wavelength conversion portions has a plurality of polarization structures serially disposed in the longitudinal direction of the light waveguide in such a manner that their polarities in the thickness direction of the substrate are inverted periodically and alternately in the longitudinal direction of the light waveguide. The light waveguide further includes a phase adjustment portion located between the first and second wavelength conversion portions, and associated with a pair of electrodes disposed in opposed relation to one another on opposite sides thereof. The light-intensity modulation element of the present invention can modulate a light intensity in a compact structure and with enhanced efficiency of conversion to second harmonics.

A very thin semiconductor film is used for channels of semiconductor memory elements such that leak currents are reduced by the quantum-mechanical containment effect in the direction of film thickness. The amount of electrical charge accumulated in each charge accumulating region is used to change the conductance between a source region and a drain region of each read transistor structure. This conductance change is utilized for data storage. The thickness of the channel of the write transistor structure is preferably no more than 5 nm. According to one embodiment, the channel of the write transistor is formed by a semiconductor film deposited on a surface intersecting a principal plane of the substrate.

In a pump operation control apparatus for a hydraulic brake boosting system, an ECU 13 is provided with a timer 16 to which an output signal from a brake switch 12 is supplied and a pump-operation-control-signal generating means 17 for transmitting a signal for operating and controlling a motor 9 in response to an output signal from the timer 16. When the brake switch 12 has been switched on, the operation of the pump is started. After predetermined time T has elapsed from a moment at which the brake switch 12 has been switched on, the operation of the pump is interrupted. If the brake switch 12 is continuously switched on after the predetermined time T has elapsed, the pump is operated for time elongated from the predetermined time T until the brake switch 12 is switched off. If the brake switch 12 is again switched on before the predetermined time T elapses, the pump is operated until the predetermined time T elapses from the moment at which the brake switch 12 has again been switched on.

In a method of controlling an electric power steering apparatus by controlling a drive force of a steering force assisting electric motor when a vehicle speed is lower than a predetermined speed and controlling a braking force of the electric motor when the vehicle speed exceeds the predetermined speed, a steering wheel forward or reverse turning state is determined in accordance with a change in steering torque when the vehicle speed exceeds the predetermined state. The braking force of the electric motor is controlled only when the steering wheel reverse turning state is detected.
