Title: High-temperature impact powder solidification molding method and powder solidification molding device
Inventor: FUJITA MASAHIRO
IPC: B30B11/00
Filed: 1994-08-16
Abstract: PURPOSE: To execute solidification molding of powders of extremely high- hardness materials including diamond in a high-temp. state. CONSTITUTION: The raw material powder to be molded us packed into a powder packing section 7 and an explosive 2 is set above this power apart therefrom. After the powder part is heated, the explosive part is set right above the powder packing section. Detonation waves are generated from inside the explosive 2 when a detonator 1 is initiated thereafter. These detonation waves are transmitted via water to the powder and an ultra-high pressure acts on the powder. The hard powder is thus subjected to the solidification molding.

Abstract: PURPOSE:To improve reliability by providing one- or two-dimensional photodetector provided on the imaging plane of an image pickup lens or in the position conjugate therewith and a differentiation circuit which differentiates the output thereof, and deciding the max. value of the output from the differentiation circuit. CONSTITUTION:The image from an object 1 is formed on an imaging plane 11 by an image pickup lens 10, and is formed also on the photodetection surface of a two-dimensional photodetector 13 by a half mirror 12 provided in the mid-way of the optical path. Since the photodetection surface of the photodetector 13 is disposed in the position having a conjugate relation with the plane 11, the image equivalent to the image on the plane 11 is photoelectrically converted. The electrical output of the detector 13 is further two-dimensionally differentiated by a space differentiation circuit 14 and an average differentiated value is outputted to a decision circuit 15 for the differentiated value. The average differentiated value of the space frequency in the circuit 15 is maximized where the image is focussed if said value is measured while the position of the lens 10 is changed in either of the direction S. A focused state is thus obtd. if the point of such time is detected and the stop signal for the lens 10 is transmitted.

Title: Gaas field-effect transistor
Inventor: OTSUKI TATSUO
IPC: H01L29/47
Filed: 1984-09-14
Abstract: PURPOSE:To form a GaAs field-effect transistor, which has low resistance and uniform Schottky characteristics in a wafer surface and in which a problem of which a Schottky electrode is peeled from a substrate is not generated, by forming a heat-resistant Schottky gate consisting of two layers of W and TaWSi. CONSTITUTION:Treatment before evaporating a Schottky gate is executed to a substrate 1, the substrate is introduced instantaneously to a sputtering metallizing apparatus, Ar is admitted when pressure reaches 4X10<-4>Pa or lower, and tungsten is evaporated in 50nm at pressure of 1X10<-1>Pa and Pf=150W. When the thickness of tungsten extends over 50nm or lower, 'peeling' due to the difference of thermal expansion coefficients with the GaAs substrate is not generated. A Ta15W75Si10 layer 6 is evaporated through a simultaneous sputtering method under the same conditions. The thermal expansion coefficient of the layer 6 having the composition is equal to that of GaAs, and the layer 6 is not peeled even when it is evaporated in 200nm. The thickness of 250nm in total of a W layer 5 and the Ta15W75Si10 layer 6 functions as a mask for self-alignment at a time when N<+> ions are implanted to source-drain regions. Accordingly, a GaAs/W/Ta15W75Si10 Schottky gate is formed.

Title: Hardness detector
Inventor: HIRANO AKIRA
IPC: B25J9/16
Filed: 1984-09-14
Abstract: PURPOSE:To detect instantaneously, precisely and easily the hardness of a substance by pressing a pressure detector against the substance and vibrating the pressure detector to change the contact pressure periodically. CONSTITUTION:The substance W to be measured is sandwiched between the pressure detector 3 and finger 4. The pressure detector 3 is arranged on a diaphragm 2 and a permanent magnet 5 is arranged on its opposite side. When AC is applied to an exciting coil 6, absorbing force and repulsion are alternately applied to the permanent magnet 5 and the pressure detector 3 is vibrated. When the substance W is hard, the amplitude detected by the detector 3 is large, and in case of a soft substance, the amplitude is small. Since the contact pressure of the detector 3 with the substance W is changed, the hardness of the substance W can be precisely detected.

Title: Solution and method for cleaning semiconductor substrate
Inventor: TAKADA RYOKO
IPC: C11D7/28
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To properly remove both metallic impurities and fine particles which adhere to the surface of a semiconductor substrate. SOLUTION: In a cleaning method, a contaminated semiconductor substrate 11 is cleaned with a cleaning solution, containing 0.1-50 wt.% organic acid and 0.005-0.25 wt.% hydrofluoric acid having a pH value of or less. When the substrate 11 is dipped in the cleaning solution, a natural oxide film 12 formed on the surface of the substrate 11 is removed by the hydrofluoric acid and the fine particles 13 and metallic impurities 14 on the film 12 and the metallic impurities 14 in the film 12 migrate into the solution. Since the cleaning solution is an acidic solution containing organic acid and has a pH value of 4 or less, the fine particles 13 are charged negatively similar to the surface of the substrate 11, and at the same time, the metallic impurity ions in the solution become negative complex ions due to the complexing effect of the organic acid.  Consequently, the adhesion or re-adhesion of the fine particles 13 and metallic impurities 14 to the substrate 11 is prevented, because the surface potentials of the particles 13 and impurities 14 become negative, similar to that of the substrate 11.
