Abstract: PURPOSE: To provide a fine pixel plane display which can represent static or dynamic video by using an optical switch, utilizing an electrostatic microactuator manufactured only by a semiconductor process. CONSTITUTION: A shutter-moving element 14 at an arbitrary position in a frame 15 is electrostatically charged in a belt-like shape by applying a select electrode 3 and a signal electrode 2 with voltages which are respectively higher and lower than the voltage of a common electrode 4. When an equilibrium state is reached, the voltage applied to the select line is inverted in polarity, in order and then the electric charges of the select electrode 3 change momentarily, but electric charges which accumulated on the side of the moving element 14 are unable to migrate immediately because of disturbance by the resistance. Consequently, a driving for which moves the moving element 14 to the right is generated, together with a repulsive force between the moving element 14 and select electrode 3, so that the shutter-moving element 14 moves to the right side.

Abstract: PURPOSE: To prevent the degradation in a yield with an increase in size, to lessen the resistance of gate bus lines and to minimize the shorting between wirings from gate insulating films or the intersected parts of the wirings. CONSTITUTION: This process for production includes a stage for producing unit thin-film transistor(TFT) panels on a polyimide supporting base 33 and a stage for aligning and fixing the unit TFT panels in matrix on a glass substrate 17, then electrically connecting and joining the drain bus lines and gate bus lines of the ends of the unit TFT panels to be joined to each other by an ink jet method. The unit TFT panels are constituted by forming gate metals of three layers Cr/Cu/Cr, forming the respective gate bus lines and drain bus lines on the upper and lower surfaces of the polyimide thin films and connecting drain pads and the drain bus lines by a via hole stage.

Abstract: PURPOSE: To simplify configuration requiring no additional circuit for inserting one additional bit into the output of a pseudo random number sequence (PN) by generating a new comparison value corresponding to a PN mask value, while using a comparison value translator. CONSTITUTION: After an initial LSSR load state signal has been received, a PN generator (LSSR) 100 executes shift operation, based on a sequential enable signal and generates a PN sequence. After the initial comparison value has been received, a comparison value translator 500 converts that value to a value corresponding to PN mask data. A comparator 200 compares the output of PN generator 100 with the converted comparison value. A D flip-flop 110, inverter 120 and an AND gate 130 are operated as a means for adding '0' of one bit at a prescribed bit position, after delaying the LSSR state value for one cycle when the LSSR state value is equal with the converted comparison value.

Abstract: PURPOSE: To provide an optical open/close equipment where a micro-electrostatic actuator produced only by semiconductor process is utilized and its producing method. CONSTITUTION: Positive and negative voltages are applied to a selection electrode 3 and a signal electrode 2, to make a traveling element 12 electrified. When the impressed voltage polarity of the signal electrode 2 changes instantaneously, an electric charge electrified to be band-shaped at a traveling element side does not immediately react, owing to the resistance of the travelling element 12. Therefore, driving force for moving the travelling element 12 to a left side occurs together with the repulsion between the travelling element 12 and the electrode 2, so that a shutter travelling element 12 is moved.
