Title: Cathode structure of magnetron
Inventor: OGURA TOSHIO
IPC: H01J23/14
Filed: 1989-12-15
Abstract: PURPOSE:To prevent filament breaking by making an end part a molybdenum- made lead running through a tandem plate free movable inside a hole furnished with a bottom of a stem while making a ringshaped recessed part of a ringshaped rib provided around a tandem plate through hole to catch surplus hard solder. CONSTITUTION:A center lead 1 made of molybdenum is supported only by a tandem plate 2 in order to be free movable inside a hole 4 furnished with a bottom provided on a ceramic-made stem 3. A surplus portion of hard solder 5 soldered to them metallized surface orthogonal to a tube axis of the stem 3 of a tandem plate 2 is caught by a ring-shaped recessed part formed on the rear of a ring-shaped rib 8 projected to the tube inside around a through hole of the tandem plate 2 thus to prevent the invasion to the inside of the hole 4 furnished with a bottom. Accordingly, an end part of the center lead 1 is excluded from being stuck to the inner wall of the hole in the inner depth of the hole 4 furnished with a bottom. Thereby, breaking of a cathode filament due to vibration and impact is prevented while saving the use of the molybdenum-made lead.

Title: Storing process system for graphic element
Inventor: YOSHIDA KEIJI
IPC: G06T1/00
Filed: 1988-12-20
Abstract: PURPOSE:To shorten the processing time when the graphic elements are stored by opening the idle area of an element control table at the end of a segment. CONSTITUTION:When a command received from a host computer is identified as an element output command, a new element control table 2 is acquired as long as the old table 2 includes no idle area. Then the element data 1 is stored in a memory and a pointer, etc., to the store address of the memory are set at the table 2. In case the command received from the host computer shows a segment end command, the idle area of the table 2 is opened. Thus the idle area of the table 2 is not opened for a period covering the start through the end of a segment, and a pointer is set to an element instead. Thus the processing time is shortened when a graphic element is stored compared with the conventional method where the idle area is opened for each element output command.
