Title: Method for plasma etching
Inventor: SHINTANI MASAKI
IPC: H01L21/3065
Filed: 1984-04-13
Abstract: PURPOSE:To obtain the state wherein an anisotropic etching is easily accomplished and to have the state suited for employment of microscopic working technique by a method wherein a mixed gas, in which hydrogen gas is added besides chlorine reaction gas, is used as the reaction gas to be used when a plasma etching is performed on aluminum or an aluminum alloy. CONSTITUTION:A mixed gas in which hydrogen gas is added besides carbon tetrachloride and trichloroboron is used as the reaction gas to be used when a plasma etching is performed on aluminum. When said plasma etching is going to be performed, a hydrocarbon polymer is grown on the side wall part of an aluminum film, and an anisotropic etching can be accomplished. This hydrocarbon polymer can be removed easily by performing an oxygen plasma treatment. The content of hydrogen gas of approximately 10-50vol% is considered practicable. When hydrogen gas is mixed, cathode dropping voltage is boosted, an anisotropic etching can be accomplished even when making power density is low, and the ratio of selectivity can be increased.

Title: Method and machine for compression molding permanent magnet alloy powder
Inventor: MOCHIZUKI MITSUAKI
IPC: H01F41/02
Filed: 1994-04-12
Abstract: PURPOSE:To produce a permanent magnet excellent in characteristic, as compared with a permanent magnet produced through parallel magnetic field molding, easily at low cost.

Abstract: PURPOSE:To eliminate a switching element and an energy loss so as to improve a device of this design in performance and stability by a method wherein a trigger circuit, which varies the voltage applied to a trigger electrode to such an extent that an electric field between primary electrodes is distubed, is provided. CONSTITUTION:Pulse signals sent to a delay circuit 34 are delayed through the delay circuit 34 and supplied to a corresponding voltage supply circuit 31 through a capacitor 33 as trigger pulses. Then, the voltage at a connecting point between resistors R1 and R2 of the corresponding voltage supply circuit 31 is made to vary, wherefore the voltages applied to trigger electrodes 30 and 30' are varied. Thus, a potential gradient between primary discharge electrodes 21 and 21' is made to vary to disturb an electric field.
