Title: Printing method on transparent body
Inventor: SASA TERUKAZU
IPC: G03F1/00
Filed: 1984-08-22
Abstract: PURPOSE:To print on a transparent optical mask, by a method wherein a transparent body is coated with a light-nontransmitting substance in its area to be irradiated with laser light, and energy of laser light is converted into heat by the light-nontransmitting substance. CONSTITUTION:When a glass plate 11 is coated with chromium only in its area for forming a mask, a brown chromium film 12 is provided, while a peripheral part 13 remains to be a transparent glass. It is impossible to print by irradiating the peripheral part 13 of the transparent glass plate with laser light. When a metallic piece 15 is kept in contact with the glass plate 11 on the side opposite to the laser side and is irradiated with laser light through the glass plate 11, the metallic piece is melted in a dot print pattern by the energy of the laser light, the thermal energy is transmitted to the glass plate 11, and the glass plate 11 is also melted by the heat, resulting in formation of a dot printed part 16 similar to the pattern formed in the metallic piece.

Abstract: PURPOSE:To enhance the recovery ratio of product gas, in a pressure swing adsorbing process, by returning a part of the exhaust gas of an adsorbing tower in a regeneration process to the supply line for gas to be purified in an adsorbing tower in a purifying process. CONSTITUTION:Stock gas is compressed by a compressor 21 to be introduced into an adsorbing tower A and N2 is removed by adsorption while product H2 is taken out. An adsorbing tower B is reduced in pressure to atmospheric pressure from an exhaust valve 3b and N2 desorbed along with residual H2 is returned to a stock gas line 11 through a pressure reducing valve 9 and a valve 14. Subsequently, a part of product H2 is introduced into the adsorbing tower B through a pressure reducing valve 6 and a valve 4b to wash an adsorbent and exhaust gas is returned to the stock gas line 11 through the pipe 14 and, subsequently, the adsorbing tower B is again pressurized by product H2-gas to prepare the next adsorbing process. Because the concns. of N2 in exhaust gases at the time of evacuation and washing rise by repeating the processes, a part of the exhaust gas is purged from a valve 10 to lower the concns. of N2 to a set level or less.

CONSTITUTION:A mixture from an intake port 6 is led firstly to a guiding surface 11 of one side and then to a guiding surface 12 of the other side of a space in a stepped part 10, to cause a swirl, when a liquid state fuel component is led in a peripheral direction by centrifugal force to become a rich mixture, while vaporization of fuel is promoted by high temperature in the side of an exhaust port 5 to improve quality of the mixture. This swirl is further led to a lower side through the stepped part 10, and a rich mixture is formed also in the periphery of the stepped part. Then secondary air is led from an introducing hole in the end of an intake stroke, and upward movement of a piston obtains a rich mixture layer A in the lower side periphery, lean mixture layer B in the top inside further a lean mixture layer C in the lower of said stepped part 10. Then a flame in a recessed part 13 from firing causes propagation such as A B C, thus good combustion of the three layers can be obtained.

Title: Manufacture and its device of magnetic recording medium
Inventor: OIWA TSUNEMI
IPC: C23C14/00
Filed: 1984-08-25
Abstract: PURPOSE:To obtain a recording medium excellent in anticorrosion without the drop of a magnetic characteristic by making the steam flow of a ferromagnetic material incident on a basic material, which moves from a high incident angle part to a low one along the peripheral side of a cylindrical can, so that the maximum incident angle of the steam flow can be within a specific range. CONSTITUTION:While a basic material 4 such as plastic film is shifted along the peripheral side of a cylindrical can 3 from an original tape roll 5 and wound to a winding roll, the steam flow shielding top 10a of a buffer plate 10 is arranged and disposed along the peripheral side of the can 3 to execute the vacuum deposition so that a maximum incident angle (alpha) of the steam flow A of a ferromagnetic material 8 can be within a range of 75-85 deg. with use of a minimum incident angle adjusting buffer plate 9 and a maximum incident angle adjusting buffer plate 10. Thus the particle size of a ferromagnetic material particle precipitated on the basic material 4 is made larger, while a space between magnetic particles in the vicinity of an interface between the basic material and a magnetic metallic thin film is made smaller: therefore the anticorrosion of a magnetic layer wherein the corrosion develops due to a corrosive component such as water in the air for entering the space can be improved. Moreover a minimum incident angle (beta) of said plate 9 is set over 45 deg. to improve the coercive force, thereby enhancing a magnetic characteristic.

Title: Method of forming pattern of tungsten wiring
Inventor: KIMU UIISON
IPC: H01L21/28
Filed: 1990-07-06
Abstract: PURPOSE: To prevent short-circuiting at the hole gap inside a tungsten wiring and that between tungsten wires by eliminating an oxide film that is doped densely by wet etching, using tungsten on a polycrystalline silicon film as an etching mask, and performing the dry etching of the polycrystalline silicon film at a part that is not covered with tungsten. CONSTITUTION: An oxide film 19 that is doped densely is deposited at the upper part of a polycrystalline silicon 18. The oxide film 19 is etched and the polycrystalline silicon 18 is exposed, and a tungsten wiring part 15 is formed on it, where a residue 20 of tungsten is formed at the upper part of the oxide film 19. When a reagent solution for etching of the oxide treated by a buffer agent is used, the oxide film 19 and the residue 20 of tungsten on it are eliminated as the same time, and only the tungsten wiring part 15 remains on the polycrystalline silicon 18. By properly setting an etching speed, only one portion of the upper part of the tungsten wiring part 15 is etched, and all the other parts of the polycrystalline silicon 18 are etched except a part that is covered with the tungsten wiring part 15, thus completing the tungsten wiring pattern.

Title: Production of copper sulfate
Inventor: ANDO KOJI
IPC: C01G3/10
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To efficiently produce high purity copper sulfate by immersing copper powder containing Ni as one of impurities into an acid solution to remove Ni contained in the copper powder by dissolving Ni, by dissolving copper powder as filter cake in sulfuric acid and by crystallization to obtain copper sulfate having an Ni grade not larger than a specific value.

As the acid solution, sulfuric acid solution having a normality not smaller than equivalents to settle the Ni and having the sulfuric acid concentration of 1 wt.% is used. By washing the copper powder before and/or after the immersion into the acid solution, Ni alone can be removed. Copper powder obtained by filtering the acid solution used for the immersion is dissolved in sulfuric acid and then crystallization is carried out to obtain copper sulfate having an Ni grade of <=10 ppm.

Title: Braking method for induction motor
Inventor: ISHIZAWA SHIROU
IPC: H02P23/06
Filed: 1981-11-07
Abstract: PURPOSE:To obtain a smooth braking control by controlling the frequency of a variable frequency voltage applied to an induction motor and consuming the current by a discharging resistor while controlling the current generated by the motor at this time, thereby decelerating the motor at the constant deceleration torque. CONSTITUTION:In case that a brake control command is inputted when an operating induction motor 3 becomes free-running upon opening of a main power source contactor 2, a brake controller 12 is operated immediately by a contactor 9. The output side contactor 4 of the brake controller 12 is closed after confirming the remaining voltage cancellation of the motor 3 from the brake control command. Since the motor 3 is operated as an induction motor after the contactor 4 is closed, the output frequency of the brake controller is  lowered, thereby discharging the power back current to the brake resistor 10. The power back current is detected by a CT 5, is compared with the set reference value of a current setter RH 6, and the controller 12 is controlled in frequency by the deviation.
