Title: Hydrocracking of heavy oil using vanadyl oxalate as catalyst
Inventor: SASAKI YOSHIYUKI
IPC: C10G47/02
Filed: 1983-03-17
Abstract: PURPOSE:To carry out the hydrocracking of a heavy oil, economically, without necessitating the recovery of V from ash, preventing the production of hardly handleable by-products, and facilitating the preparation and regeneration of catalyst, by using (an aqueous solution of) vanadyl oxalate as the hydrocracking catalyst. CONSTITUTION:Hydrocracking of a heavy oil having a heavy metal content of >=50ppm (e.g. shale oil) is carried out by reacting the oil with hydrogen at 350-500 deg.C under hydrogen prssure of 30-250kg/cm<2> using (an aqueous solution of) vanadyl oxalate as a catalyst. The preferable amount of the catalyst is 0.01-2.00wt% at the start of the reaction and 0.01-1.00wt% in the stationary state, in terms of vanadyl oxalate based on the stock oil.

Title: Manufacture of n-type semiconductor crystal
Inventor: OKAJIMA MASASUE
IPC: H01L21/365
Filed: 1987-03-02
Abstract: PURPOSE:To obtain an N-type crystal having a small electric resistance and emitting blue light at room temperature, by a method wherein when donar impurity is doped in a ZnSxSe1-x crystal, magnesium is doped at the same time. CONSTITUTION:A ZnSe 2 in which Cl and Mg are doped is grown on an N-type GaAs substrate 1. Thereon an SiO2 film 3 is formed, on which metal electrodes 4 and 5 are formed. As the ion radius of Mg is smaller than that of Zn, and Mg is liable to bond with Se, Zn vacancy is considered to be replaced by Mg, and the electrical state is neutral. Further an intrinsic luminescence band does not exist in a long wavelength region. Therefore, by doping Mg simultaneously with donar impurity, Mg itself has no effect on electrical and optical characteristics of crystal, and restrains emission in a long wavelength region. Thereby, a blue light emission of high efficiency can be obtained.

Filed: 1983-03-17
Abstract: PURPOSE:To prevent the change in the height of a torch and to perform satisfactory welding by suppressing the change in the welding current with a change in a welding speed by changing the feed speed for a welding wire. CONSTITUTION:A welding speed setter 14 sets the running speed of a torch 3 and the set value thereof is inputted to a memory 11; at the same time, said value is inputted as a command value for a welding speed to a control system 17 for running of the torch consisting of a D/A converter 15, a motor driving circuit 16 and a motor MS for running the torch. A current sensor 18 detects the magnitude of the welding current flowing in the torch 3 and the detected value is fed back via an A/D converter 19 to a subtractor 12. The current deviation outputted from the subtractor 12 is inputted as a command value of the height for the torch 3 to a control system 22 consisting of a D/A converter 20, a motor driving circuit 21 and a motor MH for controlling the height of the torch. The height of the torch 3 is thus controlled so that the welding current attains the current set by a setter 10.

Filed: 1990-02-28
Abstract: PURPOSE:To achieve predetermined flywheel effect relevant to storage of power by disposing a rotor on the outer circumference of a stator and employing the rotor as a flywheel thereby making effective use of structural member. CONSTITUTION:A rotor 22 is disposed on the outer circumference of a stator 21 in order to provide a flywheel effect. In other words, when the rotor 22 is rotating, a rotor core 27 having larger outer diameter than the stator 21 exhibits flywheel effect. Furthermore, a rotor rim 29 supporting the rotor core 27 is disposed on the outer circumference of the rotor 27 and the diameter of the rotor rim 29 is set larger than that of the rotor core 27. Consequently, the rotor rim 29 rotates together with the rotor core 27 and functions as a flywheel. Since neither a flywheel nor a spindle is required, material can be saved for achieving a predetermined flywheel effect.

Title: Refining method of stainless steel
Inventor: KINUGASA MASAHIRO
IPC: C21C7/00
Filed: 1980-04-07
Abstract: PURPOSE: To reduce load of a vacuum decarburization step for decarburizing to a  low carbon range by a method wherein high-carbon Cr-containing molten pig iron is refined in two steps, that is, the pig iron is refined by blowing oxygen and then by blowing oxygen and an inert gas.  
     CONSTITUTION: When refining the high-carbon Cr-containing molten pig iron at atmosphere pressure, decarburization to reduce the carbon content of the melt to 0.60wt% is conducted by using pure oxygen gas. Subsequently, the melt is decarburized to a carbon content of 0.15% by using oxygen gas and the inert gas. The melt obtained after the said two decarburizing steps is then refined by blowing oxygen at a reduced pressure so that the melt is decarburized to a desired carbon content of below 0.15%. Accordingly, the process time of the vacuum decarburization step is reduced. In addition, oxygen feeding efficiency is enhance and the amount of the inert gas used is reduced.

IPC: F16D35/02
Filed: 1981-03-30
Abstract: PURPOSE:To perform rotary motion of a fan in accordance with temperature of cooling water through a viscous fluid coupling suitable for driving the radiator cooling fan used in a vehicle, by feeding viscous fluid to a working chamber provided with a labyrinth ad controlling a viscous fluid amount in accordance with the temperatue of cooling water. CONSTITUTION:Low temperature of cooling water causes a control device 29 to close a relay contact 27 immediately after an engine 8 is started. In consequence, a solenoid 12 is excited to attract a magnetic core 22, and a communication hole 20 in a separator plate 19 is closed by  a flexible strip 21. Then viscous fluid in a reservoir chamber 17 is not fed to a working chamber 18, and a viscous fluid amount between said chamber and a labyrinth 5 is decreased, then a turning effect, transmitted from a rotor 6 to an inner casing 4a, is suppressed. On the contrary, the temperature of cooling water rises to open the relay contact 27, then the communication hole 20 is opened to feed much viscous fluid to the working chamber 18. Accordingly, a turning effect, transmitted from the rotor 6 to the inner housing 4a, can be increased.

Abstract: PURPOSE:To enable an operator to determine whether an automatic paper feeder can be used or not, by a method wherein which is larger an initial setting position or a minimum value of a printing head, and which is larger, a final setting position or a maximum value of the printing head, are respectively judged to detect in which of a normal paper feed direction and a reverse one printing is to be performed, and a specified message is read to be displayed. CONSTITUTION:A CPU1 sets a value obtained by subtracting 1 from the number of printing lines to a loop count in a RAM2 at the time of automatic paper feeding, and sets the number of a printing start line to the number of of a line in the RAM2. After obtaining a line qualification from the number of the line, it sets a minimum value of a setting position of each line to an initial setting position, and obtains the minimum value and a maximum value of the setting position. The minimum value herein indicates a position where an em-character of a line to be initially set is printed. The maximum value herein indicates a position where the line to be initially set is line-fed. Then, when the initial setting position is less than the minimum value of a printing head, and when the final setting position is larger than the maximum value of the printing head, paper feed in a reverse direction occurs. Therefore, the CPU1 takes out a message, 'printing can not be performed by means of an automatic paper feeder' from a ROM3 and expands it in a VRAM6. Thereafter, it is displayed on an LCD8 via an LCD interface 7.
