Title: Nitriding furnace and production of metal nitride
Inventor: NAKAMURA YOSHIYUKI
IPC: F27D1/00
Filed: 1988-09-05
Abstract: PURPOSE:To perform control of heat of reaction in the production of a metal nitride and to prevent contamination due to a heat element of a nitriding furnace by constituting a lining heat-insulating material of the furnace of an inorganic fibrous material having a specified bulk density and the heat element of Mo. CONSTITUTION:The inside surface of a nitriding furnace is lined with an inorganic fibrous heat insulating material having <=0.5 bulk density and an Mo heat element is provided to the furnace. Metal powder is charged to the furnace and nitrided by heating in N2 or atmosphere contg. NH3. If the bulk density of the heat insulating material of the furnace is >0.5, cutting-off of an electric power source becomes very difficult if an exothermic reaction once begins, and the control of the reaction becomes very difficult even if inert gas is introduced. Even if the control is attained, production of Si3N4 powder having high alpha-fraction may be hardly possible after starting the reaction anew, resulting enormous consumption of energy, causing in some case and frequently, uncontrollable reactions due to small thermal susceptibility of the furnace material. By the use of an Mo heat element, degradation of the quality of the product is avoided even if generation of CH4 occurs by the reaction of C with NH3 or H2 in the nitriding atmosphere which is caused when conventional heat element comprising C or SiC is used.

Title: Method and device for drawing electron beam
Inventor: NAKAJIMA KEN
IPC: G03F7/20
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for drawing an electron beam, which can reduce the drawing throughput of the electron beams to a significant extent. SOLUTION: A shifting amount 9 in consideration of the deflecting position in an electron-beam deflecting region 1 and the position deviation at the time of electron beam deflection depending on a distance is overlapped on the design drawing position. That is, it is not necessary to consider the stability of an applied voltage to a deflecting device, which is the cause for generating sninging delay of the electron beam deflection, because the voltage is set by using the response time for the stabilized positioning of the voltage when the preset voltage is applied on the deflecting device, and the electron beam exposure is performed. Therefore, the time until the applied voltage is stably positioned from a dummy time 8 before the irradiation of the electron beam can be made minimum. Therefore, the drawing throughput of the electron beam can be reduced markedly.

Title: Improvement to dc overlapping characteristics of mnzn ferrite
Inventor: HANDA KUNISABURO
IPC: C04B35/38
Filed: 1985-10-02
Abstract: PURPOSE:To enable dc overlapping characteristics of a sintered ferrite to be changed by easy treatment without many efforts, by performing heat treatment of the sintered ferrite in an oxidizing atmosphere. CONSTITUTION:A MnZn sintered ferrite is obtained by firing treatment, with each of raw materials mixed in a prescribed ratio, so that whole is molded into a definite shape and while its conditions of balanced oxygen pressure become satisfied in an atmosphere of inert gas such as nitrogen. The sintered ferrite obtained is heat-treated in an oxidizing atmosphere. Heat-treatment temperature ranges from 500 deg.C to less than the firing temperature of the sintered ferrite. Thus, dc overlapping characteristics can be changed in the direction where inductance is smaller in a changing ratio than that of the dc overlapping characteristics prior to the heat treatment.
