Title: Image display device
Inventor: ENOMOTO TAKASHI
IPC: G09F9/30
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To rapidly exhaust residual gas in a region interlaid between a phosphor screen and a cathode array by forming plural openings on a cathode array substrate and by setting the opening area of the plural openings on the side of a back substrate larger than that on the side of a transparent substrate. SOLUTION: The collision of gas molecules inside this image display device mainly occurs with the walls of the device, and the collision among the gas molecules can be neglected. For multiple openings 3 formed on a cathode array substrate, the width of their openings 81 on the side of a back substrate is set larger than that of their openings 82 on the side of a transparent substrate, and inner walls 83 connecting both the openings are faced to the back substrate side. Thereby, gas passing the openings 82 from the space on the transparent substrate side is allowed to almost completely reach the space on the back substrate side.  On the other hand, since the gas molecules passing the openings 81 from the space on the back substrate side are reflected by the inner walls 83, the number of the gas molecules reaching the space on the transparent substrate side from the space on the back substrate side can be restrained.

Title: Ac gas shielded arc welding method
Inventor: NOMURA HIROICHI
IPC: B23K9/06
Filed: 1978-09-20
Abstract: PURPOSE: To make refiring of AC arc easy without adding any special device by so connecting at least two proximate consumable electrodes to the AC power source as to give phase differences between the electrodes.  
     CONSTITUTION: For example, the eletrodes A of two consumable electrodes A, B is conncted to the secondary side of a welding transformer 2 whose primary side is connected to 3 phase AC v, w power sources and the electrodes B is connected to a welding transformer 3 whose primary side is connected to the u, v power sources. The welding current of the electrode A becomes zero at the a point. On the other hand, the welding current of the electrode B is late 60° in phase than the former and therefore at the a point it is the b point and the currents ab flow, thus generating normal arc to the weld base metal 1. Hence, if both electrodes are beforehand approached to a required degree based on the phase differences of both current and each current value, then the arc of the electrode B becomes a trigger at the a point of the electrode and the electrode A is readily refired. Even at the b' point, the electrode B is readily refired in the similar manner.

IPC: G05F1/56
Filed: 1981-07-23
Abstract: PURPOSE:To delay the rise of output voltage by providing a delay circuit for controlling the rise to a voltage setting circuit. CONSTITUTION:At the time of turning on a constant-voltage power supply, a transitor (TR) 7 is off. Consequently the base voltage of a TR5 is turned to the high level and the TR5 is turned on. Parallel resistance between an terminal of output voltage VOUT and a voltage setting terminal VREF is approximately ''0''. As a result, the output voltage VOUT is turned to the same level as the base voltage of the TR5. The output voltage VOUT maintains its low level until the TR7 is turned on by charging a capacitor 9. When the TR7 is turned on, the the TR5 is turned off and the resistance value between the terminal of output voltage VOUT and the voltage setting terminal VREF is turned to a normal value.
