Title: Extra-high vacuum element for charged particle beam device
Inventor: KANEKO YUTAKA
IPC: F04B37/16
Filed: 1984-07-25
Abstract: PURPOSE:To prevent any scattering of contaminant by reducing the influence of a magnetic field on an extra-high vacuum element by installing in the exhaust hole a contaminant-shielding plate which is made of a material with high permeability and also serves as an external magnetism shield. CONSTITUTION:Magnetic fluxes leaking outside through the exhaust hole 17 of an ionic pump are reduced by absorbing them into shield cylinders 22 formed by thin plates of a material with high permeability. Each of the shield cylinders 22 consists of a pipe 23 and a twisted shield plate 24 made of the same material as the pipe 23 so that contaminants such as active metal molecules which have absorbed scattering gas molecules produced in the ionic pump are shielded by a shielding plate 24 and not discharged outside. As a result, the decrease in the exhaust rate of the ionic pump is minimized, thereby reducing the amount of magnetic fluxes leaking through the exhaust hole 17 and the amount of scattering contaminates.

Abstract: PURPOSE: To improve performance and to reduce a program size. CONSTITUTION: An instruction fetch part 2 reads in an instruction and data from a memory 1, and an instruction decoding part 3 decodes them. The operation of a second operation part 7 is started by a data transfer instruction to an input register of a register group 4, and the operation result is stored in an output register. When unprocessed data remains in the input or output register, the succeeding data processing is stopped. Plural sets of input and output registers and computing elements are provided and are selected in accordance with the processing. Since prescribed operation is executed by the data transfer instruction, the processing speed is increased and the program is simplified. The extensibility is high because the addition of a special operation instruction is unnecessary.

Title: Production of silicon carbide brick having sialon linkage
Inventor: SAITO MITSUO
IPC: C04B35/56
Filed: 1988-06-24
Abstract: PURPOSE:To obtain the title brick excellent in heat shock resistance with little change in volume and physical properties in an oxidative or reducive atmosphere by press forming of a mixture comprising SiC aggregate, metallic Si powder and metallic Al powder followed by sintering in a N2 atmosphere. CONSTITUTION:Firstly, 100 pts.wt. of silicon carbide aggregate is homogeneously mixed with 15-20 pts.wt. of a blend comprising 67.5-88.8wt.% of metallic silicon powder, 3.4-8.5wt.% of metallic aluminum powder and 3-24wt.% of aluminum oxide powder. Thence, the resultant mixture is put to press forming and sintered in a nitrogen atmosphere at 1300-1500 deg.C thus obtaining the objective brick. The sintering atmosphere is required to be a nitrogen one in order to develop SIALON linkage during the sintering process. If <1300 deg.C in the sintering temperature, too long time is needed to produce firm SIALON linkage, therefore being impracticable. On the other hand, if >1500 deg.C, SIALON is rapidly formed on the surface of the sintered form to effect densification of said form; hence, a nitrogen gas cannot diffuse deep into the sintered form, therefore being unfavorable.
