Title: Quick movable type impregnated cathode
Inventor: SAKURAI ISAO
IPC: H01J9/04
Filed: 1981-01-21
Abstract: PURPOSE:To enhance the interlocking property of a quick movable type impregnated  cathode, by providing previously an opening at the place where a cathode made of a  metallic plate with a high melting temperature as a heater is desired to form, forming  a metallic powder with a high melting point into said opening in order to sinter, so  that said powder does not separate from said opening, and then impregnating said  metallic plate with an electron emissive material. CONSTITUTION:An opening smaller than in size a cathode is previously formed at the  place where a cathode made of a tungsten plate 6 is desired to form. Next, a metallic  powder with a high melting point such as tungsten or molybdenum is pressed from both sides of the tungsten plate 6 in order to form a top part and a bottom part, each having larger diameter than that of said opening. Afterwards, for instance, said powder is  sintered at 2,000-2,600 deg.C in a hydrogen furnace in order to contract a molded body 7  made of the metallic powder with a high melting point. Then, the sintered body 7 is impregnated with the electron emissive material and thereby a quick movable type impregnated cathode can be obtained. Consequently, the impregnated cathode directly  adhered to said metallic plate with a high melting point, so the temperature of the  impregnated cathode is immediately raised and the quick movability of the cathode is enhanced.

IPC: B41J19/00
Filed: 1981-01-22
Abstract: PURPOSE:To enable the use of a compact feed source for paper-feeding, by a method wherein, in a recording method to form a line by scanning a carriage a plural number of times, when a distance for the number of printing columns is shorter than that for a specified number, the carriage is caused to temporarily wait in a home position. CONSTITUTION:According to a printing command, a carriage CA moves forward, and 4 upper stages of 5-7 dot matrix are printed by nozzles N1-N4. During said printing, the number of printing columns is counted, and the counting result is compared with details of a printing column number storing resistor. If the two coincide with each other and the printing for the 4 upper stages is complete, a paper feed for 4-dot line and the return operation of the carriage are conducted in parallel to each other. If the details of the printing column number storing resistor exceeds a reference value, the carriage CA executes printing of successive 3 lower stages from a home position immediately. If however, the details of the column number storing resistor is below the reference value, the carriage CA waits at a rightmost end temporarily until a printing is complete, and then a printing for a next stage is executed.

Title: Burning device of ceramic forming material
Inventor: TERASAKI MASANORI
IPC: F27B7/18
Filed: 1995-01-23
Abstract: PURPOSE: To uniformly burn a ceramic forming material by heating a core pipe having an elliptical or polygonal inner structure and passing the ceramic forming material therethrough. CONSTITUTION: A core pipe 3 is rotated by a driving part 6 and the temperature of the core pipe 3 is set to a prescribed temperature by a heater 4. When a ceramic forming material is charged from an inlet, it moves laterally while rotating owing to the rotation and inclination of the core pipe 3 and is discharged from an outlet after the lapse of a prescribed time. The ceramic forming material is heated and burnt by the heater 4 during this period. Since the inner structure of the core pipe is elliptical or polygonal in its shape, the reversibility of the ceramic forming material is improved when the core pipe 3 rotates. Thus, all the ceramic forming material can be uniformly burnt. Further, since the rotating capability of the ceramic forming material is improved. the ceramic forming material is prevented from adhering to an inner wall. Thus, an operating time can be reduced.
