Title: Production of carbon thin film
Inventor: YOSHIMOTO YOSHIKAZU
IPC: C01B31/02
Filed: 1985-03-20
Abstract: PURPOSE:To obtain a carbon thin film having improved crystallizability, by feeding a hydrocarbon to a reaction system, and forming a carbon deposit on a crystal substrate by low-temperature thermal decomposition. CONSTITUTION:An argon gas is fed from the gas control system 2 to the valve container 1 in which a hydrocarbon such as benzene purified by vacuum distillation is put to bubble benzene, and benzene molecules are sent through the glass tube 3 to the reaction tube 4. On the other hand, an argon gas is made to flow the diluting line 6, and the density of the benzene molecules in the argon gas in the glass tube 3 just before being fed to the reaction tube 4 is made fittest. A growth substrate in the reaction tube 4 is kept at about 1,000 deg.C by the furnace 8. When the benzene molecules are fed to the reaction tube 4, they are thermally decomposed in the reaction tube, and carbon deposit having a metallic luster is formed on the growth substrate. An aromatic hydrocarbon or unsaturated hydrocarbon is preferable as the hydrocarbon used.

Filed: 1987-03-12
Abstract: PURPOSE:To regenerate a moisture sensing element by heat, by electrically energizing an electrode plate formed on the moisture sensing element. CONSTITUTION:A moisture sensing element 3 is formed on a platinum thick film 2 as the first electrode plate formed on a ceramic base substrate 1. Moreover, a heater thick film 4 is formed thereon as the second electrode. Then, a part where the platinum thick film 2 of the base substrate 1 is formed is surrounded by four clearances 5.

Title: Snow board pliable in circular arc
Inventor: GUNJI MITSUHIRO
IPC: A63C5/00
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To achieve an ideal turn by connecting the central part of plates each provided with a boot mounting part to the upper center of each snow board to make the snowboards pliable. SOLUTION: The central part of plates 2 each provided with a book mounting part 3 of each snowboard 1 is connected to the upper center of the snowboard 1. As a result, a pressure is concentrated at the central part so that the snowboards 1 are made pliant intensely to accomplish turn effectively. In this process, the combination of bar-shaped members in a structure of the plate 2 achieves a higher strength and a lighter weight. The snowboards 1 thus obtained absorb impact as caused by raggedness of the surface of snow to enhance stability of gliding. The positions of both feet are so higher than the surface of snow to enable turn with the snowboards 1 sharply levelled. Moreover, even when the width of a boot is larger than the width of a board at the boot mounting position, there is no contact with the surface of the snow thereby increasing the freedom of a mounting angle.

Abstract: PURPOSE:To improve the linearily to a control signal by connecting a capacity element which functions to vary the oscillation frequency of a crystal oscillator circuit to an oscillator circuit on time division basis by a switching element in accordance with a digital control signal. CONSTITUTION:An N-bit digital signal is supplied to a binary rate multiplier 48 via a control signal line 49, and the pulses are produced in the number corresponding to the control signals. A CMOS switch 43 closes just for a period nT1 in a cycle T0 to connect a capacitor 44 between the earth and the input of an MOS inverter 40. This equals to a case where the capacity C0XnT1/T0 is always connected between the earth and the input of the inverter 40. In this case, the capacity of the capacitor 44 is defined as C0. As a result, control is possible for an oscillation frequency having extremely satisfactory linearity.

Abstract: PURPOSE:To prevent any defective crystal such as pits from occuring on an epitaxial crystalline layer by a method wherein a dummy wafer is melted in a melting solution and then the composition of melting solution is changed to be bonded on a substrate while compound semiconductor crystals with differ ent compositions are formed into multilayered structure. CONSTITUTION:A dummy wafer 15 is brought into contact with melting solution 16 while a heating furnace is heated up to 490 deg.C to melt the constituent of dummy wafer 15 in the melting solution 16. Thus, the composition of melting solution 16 is shifted from a point A to another point B also to the part near the point of intersection of a liquid line 32 at 500 deg.C and a solid phase line 42 at X=0.3 changing to another melting solution 18 with the value of x=0.3 at that time equivalent to Hg1-xCdxTe. Next, an ampule 17 is further turned by 180 degrees in the arrow g direction while cooling down the heating furnace. Then, the substrate 13 is brought into contact with the melting solution 18 with Hg1-xCdxTe at x=0.3 to epitaxially grow a crystalline layer with Hg1-xCdxTe at x=0.3 as a crystalline layer of the second layer. Through these procedures, the crystalline layers can be formed continuously into multilayered structure by simple process.

The powder mixtures are pre-densified to form green bodies in block form and are then introduced into casings or coated with a material forming a vacuum-tight casing. The pre-densified green bodies in the vacuum-tight casing are then subjected to the isostatic hot-pressing process in a high-pressure autoclave, using an inert gas such as argon, as pressure-transmission medium. The article formed from the mixed materials are used to manufacture evaporation boats for the vacuum evaporation of metals.
