IPC: C23C8/36
Filed: 1987-09-30
Abstract: PURPOSE:To form an Al-O-N-type layer excellent in wear resistance, water resistance, and corrosion resistance on the surface of an Al member by placing an Al or Al-alloy member into a hermetically sealed vessel, removing residual gas in the above vessel, heating the Al member, activating the surface, introducing an oxygen-containing nitrogen gas, and then carrying out glow discharge. CONSTITUTION:A member 3 made of Al or Al alloy is placed on a base 2 in a hermetically sealed vessel 1, and then, the pressure in the vessel 1 is reduced by means of a vacuum pump 8, e.g., to 10<-3>Torr and heating is applied by means of heaters 10, by which water vapor and residual gas are completely excluded. Subsequently, H2 gas is introduced as a gas for temperature rise, and DC discharge is initiated between an anode 12 made of stainless steel and the base 2 as a cathode to raise the temperature of the Al member 3 up to about 500 deg.C. Then, Ar is introduced as a gas for activation and the surface of the Al member 3 is activated by means of electric discharge, and an N2 gas containing 0.2-100ppm O2 is introduced to carry out glow discharge in the hermetically sealed vessel 1, by which the surface of the Al member 3 is subjected to nitriding treatment at 300-550 deg.C. By this method, the aluminum oxynitride layer containing 1-20wt.% O2 and excellent in corrosion resistance, etc., can be formed to 1-50mum thickness.

Title: Oscillator free from temperature dependency
Inventor: STECKER JOHANNES
IPC: H03L1/02
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a clock signal irrespective of a temperature change by accumulating charges from current supplied from a current source without temperature dependency and outputting one voltage in accordance with the quantity of the charges. SOLUTION: Current ic flowing from a node 409 to second supply potential (ground) through a capacitor C 410 becomes the sum of current i1 and current i2 , When a voltage level in the node 409 is reduced by a reset transistor 414, a voltage level becomes smaller than reference voltage VREF and a differential amplifier 412 moves to a low logic level. Thus, an output pulse generator 416 generates a periodical pulse. An oscillator 400 is given by the combination of current it and current i2 , which form current ic . Current i1 has temperature dependency by which the value increases when a temperature increases and current i2 has that by which the value reduces when the temperature increases. Thus, currents which oppositely depend on each other are combined to form current ic .
