Title: Projection type display device
Inventor: MISAWA TOSHIYUKI
IPC: G02F1/1368
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To improve moisture resistance of a driver circuit by coating the circuit with the passivation film having the specification that is superior than a certain specification and removing the film from a pixel matrix. SOLUTION: An active matrix panel is provided with the pixel matrix, which has plural gate and source lines and the transistors connected to the gate and the source lines, and the gate line driver circuit which supplies signals to the gate lines on a substrate. In order to maintain the moisture resistance, the driver circuit section is covered by a passivation film 85 having the film thickness of more than a certain value (for example, approximately 1 μm). It is most effective to make the film 85 by forming the film 85 over the entire active matrix substrate and removing the film excluding for the portion of the driver section. Therefore, the film 85 is constituted of the material, which is processed by the etching liquid that does not affect insulating films 84 and 95, for example polyimide.

Title: Dynamic focus circuit
Inventor: KASHIWAGI SHIGERU
IPC: H04N3/26
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To provide an optimum focus voltage value over the whole surface of a picture tube by simple circuit constitution by providing a focus transformer in which a generated voltage at both ends of a first coupling capacitor is added to a primary coil and an output voltage obtained in a secondary coil is added to the focus electrode of the picture tube. SOLUTION: The central part of the waveform of the both terminal voltage Vpb2 of an S-shaped correcting capacitor 5 projects but the waveform of the both terminal voltage V2r of a secondary resonance capacitor 13 is a sinewave with the period of about half a horizontal deflection period. Therefore the voltage waveform Vpb3 of both terminals of the first coupling capacitor 14 becomes a form obtained by subtracting this sinewave V2r from the voltage waveform Vpb2, and a voltage waveform Vpb3 becomes a waveform formed by inversely recessing the projecting part of the vertex part of the voltage waveform Vpb2. Consequently at the time of inversely boosting the voltage waveform Vpb3 through the focus transformer 10, a waveform Vpb4 where its center is slightly recessed and both scanning terminals are raised steeply is obtained and this waveform is added to a focus electrode (f).

Filed: 1989-12-22
Abstract: PURPOSE:To detect trouble in feeder line and remote sense line positively by interrupting power supply to a load based on an output from a voltage detecting circuit for detecting abnormality of voltage across load power source terminals through voltage monitoring lines. CONSTITUTION:A voltage comparator 12 and a reference voltage source 13 make a judgment whether the difference between a terminal voltage and a normal voltage is within a predetermined range. Judgment is made whether the difference is within + or -5%, for example, and a value for enabling detection of disconnection fault of feeder line 3 and remote line 4 is selected while taking account of the load 2 current and the line resistance of the feeder line 3. When voltage comparators 12-1, 12-2 operate to produce outputs, any one of them is transmitted through an OR gate 14 to a terminal 15. Consequently an alarm is produced from the terminal 15 and the circuitry to the terminals 1.1, 1.2 of a power supply 1 is interrupted thus preventing application of abnormal voltage onto the load 2.
