Title: X-ray tube
Inventor: HOSOKAWA TATSUZO
IPC: H01J35/06
Filed: 1989-03-24
Abstract: PURPOSE:To make uniform the current density of an electron beam at an anode and enhance the picture quality by furnishing No.1, No.2 filament, and increasing those of electrons emitted from the filaments which run straight toward the anode. CONSTITUTION:A filament coil 2 and a filament 3 are arranged so that the filament coil top 21 and the filament 3 are flush with the surface of an opening provided. Therefore, the potential distribution in the spaces of filament coil 2 and filament 3 closer to the anode becomes flat. This increases those of the electrons emitted from the filament coil 2 which run straight toward the anode, i.e. those electrons running in the direction perpendicularly to the surface 13 of the opening. Therefore, the anode is free from generation of sub-peak or twin peaks in the current density of electron beam, which will thus become flat in the direction across the width of focus, resulting in emission of uniforms X-rays from anode to lead to enhancement of the picture quality.

Title: Drilling method for printed board
Inventor: YAMADA ZENJI
IPC: B23Q15/14
Filed: 1992-02-21
Abstract: PURPOSE:To shorten the air-cutting time of a drill for efficiently drilling a printed board at high speed by lowering the drill at rapid speed between a lift stand-by position and a feed speed change-over position. CONSTITUTION:A feed speed change-over position B is set up at an optional position between a lift stand-by position A and a drilling start position C. A drill 4 is lowered at rapid speed between the lift stand-by position A and the feed speed change-over position B, and lowered at drilling feed speed at a position below the feed speed change-over position B. In this case, the rapid traverse speed is set up to be faster than the drilling feed speed.

Abstract: PROBLEM TO BE SOLVED: To provide a rectifier and a rectifying apparatus having low loss and are large breakdown strength, with a simple constitution which does not require a reference power source. SOLUTION: When the voltage for turning off transistors Q1 and Q3 are applied between the emitter and the collector of a transistor Q3, the transistor Q1 is turned off, and voltage drop does not appear across a resistor R3, and the transistors Q2 and Q3 are turned off, too. When the transistor Q1 is turned on, the voltage drop appear across the resistor R1, and the transistors Q2 and Q3 are turned on.
