Abstract: PURPOSE:To improve stability and durability by adopting the dispersion strengthened overlaying alloy with which chromium carbide particles and niobium carbide coexist respectively at specific % in an Ni-based or Co-based heat resisting alloy matrix and which has an excellent high-temp. tensile creep characteristic. CONSTITUTION:The above-mentioned alloy is formed of the composite structure with which 2 to 20wt.% niobium carbide particles and 25 to 55% chromium carbide particles coexist as dispersion phase particles in the Ni-based or Co-based heat resisting alloy matrix. This alloy has the high-temp. wear resistance and oxidation resistance by the chromium carbide particles and the good high-temp. tensile creep characteristic as the dispersion effect of the niobium carbide particles and has also the high-temp. strength by the dispersion strengthening effect of these particles. Since the alloy has excellent tensile creep resistance together with the wear resistance, softening resistance, etc., in a high-temp. region, the stability and durability are improved by applying the alloy as the material or high-temp. fans, etc., for which the various characteristics mentioned above are required or the members used for acting tensile stresses in high- temp. environment.

Title: Method and device for cleaning substrate
Inventor: NISHIMURA JOICHI
IPC: H01L21/304
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To suppress damages to a substrate by evenly cleaning the entire surface to be cleaned of the substrate. SOLUTION: When a substrate is cleaned by including a process in which a cleaning brush is moved horizontally along the surface of the substrate in a state, where the cleaning brush is pressed against the surface of the substrate with a prescribed pressing force, while the substrate is rotated around the vertical axial center J of the substrate, the substrate is cleaned by monitoring the position of the cleaning brush on the surface of the substrate and changing the pressing force applied to the brush for pressing brush against the surface of the substrate so that the pressing force becomes optimum at each position. The pressing force is changed so that the force becomes stronger as the brush moves, when the brush is moved toward the outer peripheral section G (G1 and G2) of the substrate from the center J.  When the brush is moved towards the center J from the outer peripheral section G (G1 and G2), the pressing force is changed, so that the force becomes weaker as the brush moves.

Title: Field deciding circuit
Inventor: OKADA HISAO
IPC: H04N5/10
Filed: 1993-02-16
Abstract: PURPOSE:To reduce the number of gates without lowering reliability by receiving the predetermined number of compared results and supplying specific signals to a field information generation means corresponding to the result of evaluating whether or not the compared results satisfy predetermined relation. CONSTITUTION:For the predetermined number of fields, when all the results of comparing field information JFD inputted from a field judging circuit 2 with the field information FD generated by a field information generation circuit 3 are discordant, a correction circuit 7 does not generate pulse signals VCK. As a result, since the circuit 3 does not change the information FD in the next field, the information FD coincides with the information JFD inputted from the circuit 2. Thus, thereafter, a state where the information JFD outputted from the circuit 2 and the information outputted from a field deciding circuit 1 coincide continues as long as malfunction does not occur in the circuit 2.

Title: Formation of photo resist stencil
Inventor: ABE HIROYUKI
IPC: H01L21/3065
Filed: 1982-02-22
Abstract: PURPOSE:To prevent deterioration of the resist pattern by a method wherein a two-layer structural photo resist layer is exposed using a mask, the second layer is developed, and the exposed surface of the first layer and the surface of the surviving second layer are etched in gas plasma containing at least oxygen molecules. CONSTITUTION:When the surface of the photo resist layer is exposed to plasma of molecules containing fluorine, the surface layer 23 whose solvent resistant property is strengthened is formed on the surface. The two-layer structural photo resist layer is exposed using a mask, and when it is dipt in a developer to develope the second layer, the surface of the first layer is exposed leaving the unexposed part. When it is etched gas plasma having the anisotropic etching effect, the resist layer is removed according to oxygen ions, while because etching advances only in the direction perpendicular to the wafer surface, and does not advance in the lateral direction, the pattern transcribed to the second photo resist layer from the photo mask survives as it is. The first resist layer is developed and is saturated with an etching liquid, and the stencil having the mushroom-shape cross-section can be obtained.

Filed: 1983-02-21
Abstract: PURPOSE:To modulate an output signal of a mixer in the frequency range beyond millimeter wave by turning ON or OFF the output of a local oscillator connected to the mixer using a Josephson element to eliminate a ferrite switch. CONSTITUTION:A signal received with an antenna 1 is inputted into a mixer 16 having a Josephson element. When a local oscillation output switch 14 is turned ON, an IF output corresponding to an input signal is obtained at the output of a low pass filter 17 while when it is turned OFF, the output of the low pass filter 17 is down to zero. As the local oscillation output switch 14 is turned ON or OFF at a fixed cycle of several msec using a local oscillation output switch controller 15, a measuring signal and a certain square wave with the frequency of several hundred Hz comprising two signal levels, the one a level of sum of a measuring signal and a signal of a relative noise source 4 and the other a level of a signal from the comparative noise source 4 alone is obtained at the output terminal of a directional connector 18. After amplified with an IF section 5, the square signal enters a square detector 6 and a synchronous detector 7 to obtain a voltage proportional to a level difference in the square waves thereby enabling the modulation of input signals beyond the millimeter wave range.
