Title: Dry type stack gas desulfurization method for recovering simple substance sulfur
Inventor: KANDA OSAMU
IPC: B01D53/81
Filed: 1980-03-31
Abstract: PURPOSE: To remove the fly ashes in simple substance sulfur vapor and enhance the purity of recovered simple substance sulfur solids by treating the gas contg. simple substance sulfur vapor obtained by treating the SO 2  in a stack gas with γ-alumina balls prior to cooling and condensing of the same.  
     CONSTITUTION: The concd. gaseous SO 2  obtained by adsorbing and desorbing the SO 2  in a boiler stack gas is sent through a conduit 11 into an SO 2  reducing device 1, where it is subjected to high-temp. reduction treatment with the reducing agent supplied through a conduit 12, and is thereby converted to a gas contg. simple substance sulfur vapor. Thence, the gas contg. simple substance sulfur vapor is introduced into a cyclone type dust remover 2 and is removed of coarse dusts therein, after which it is conducted into a moving type dust remover 4 packed with γ-alumina balls (about 2mmϕ), where it is removed of fly ashes, thence in a sulfur cooling condenser 3, it is cooled and condensed, whereby the simple substance sulfur solids of high purity are recovered. On the other hand, the γ-alumina balls are removed of fly ashes in a dust separator 5 connected to the dust remover 4, thence they are returned into the dust remover 4 through a conduit 23.

Title: Core structure of steering wheel
Inventor: NAGATA ATSUSHI
IPC: B62D1/08
Filed: 1993-03-02
Abstract: PURPOSE:To sufficiently exert inherent functions under normal use and to absorb impact force at the application of the impact force. CONSTITUTION:A core 3 is provided with ring parts 4 and a spoke part 6. The spoke part 6 is composed of a covering body 7 having rigidity, and an insert 8 buried' in the covering body 7 and having softness. A bending part 9 is formed on the intermediate part of the insert 8. The site of the covering body 7 corresponding to the bending part 9 is partially formed in thin thickness shape. The covering body 7 has rigidity under normal use, assuring the inherent rigidity of the spoke part 6. When impact force is applied, at the site corresponding to the bending part 9, the covering body 7 at its thin thickness-formed covering body 7 has strength lower than that at the other sites. Thus, the covering body 7 is destructed at the bending part 9 to deform the spoke part 6, absorbing the impact force. The insert 8 is bent at the bending part 9.

Title: Manufacture of vapor-deposition galvanized steel
Inventor: FUKUI YASUSHI
IPC: C23C14/02
Filed: 1992-01-31
Abstract: PURPOSE:To activate the surface of a steel by ion beam etching with small quantity of irradiation and to manufacture a vapor-deposition galvanized steel sheet suitable for a high speed line. CONSTITUTION:The surface of a steel sheet is slightly etched by Ar ion beams, thereafter vapor-deposited with Al with >=0.05g/m<2> coating weight, then vapor- deposited with Zn. The quantity of the irradiation of the Ar ion beams required for forming a vapor-deposition galvanized layer having good adhesion is reduced to 0.002 coulomb/m<2> by the lower limit value by the Al vapor-deposition. Furthermore, when easily oxidizable elements such as Si, Cr and Al are incorporated into the steel, the quantity of the irradiation of the Ar ion beams to be required is moreover reduced. The vapor-deposited Al is firmly bonded to the base steel even if there is a little oxidized film and furthermore provides the surface having high activity. Thus, even if the quantity of irradiation at the time of ion beam etching is reduced, the objective vapor-deposition galvanized layer excellent in adhesion can be formed.

Title: Control system for traveling wave tube amplifier
Inventor: MAKISHIMA HIDEO
IPC: H03F1/52
Filed: 1988-02-26
Abstract: PURPOSE:To simplify the function of a power supply for satellite mount and to attain small size, light weight and high reliability of a power supply by omitting an excess spiral current detection/power supply interruption function from the satellite mount power supply and providing the function in the traveling tube amplifier controller of a ground installation. CONSTITUTION:Even when the power supply 3 has a function detecting and interrupting a spiral current excess, the merit is less on an orbit. On the other hand, in the ground test and adjustment, since various kinds of processes exist, the possibility of impressing an abnormal voltage to the traveling wave tube 1 is considerably larger than the possibility of the occurrence on the orbit. Thus, the function to detect an excess spiral current from the satellite mount power supply to interrupt the power supply is eliminated and the function of detecting the excess of spiral current based on a telemetric signal of the spiral current to send the current interruption command is provided to on-ground test equipment. Thus, the operation is made stable and the weight is made light and the control to protect surely the traveling wave tube is attained even in the ground test and adjustment.

Title: Manufacture of carbide field emitter
Inventor: HOUJIYOU HISAO
IPC: H01J1/304
Filed: 1978-04-12
Abstract: PURPOSE:To realize a method of manufacturing a crystalline carbide field emitter which suits to the electron-beam source of an electron-beam applied apparatus such as an electron microscope. CONSTITUTION:Material 1 made of penetration type carbide formation metal is formed in a chip shape by electrolytic polishing. Next, the chip is heat-annealed under vacuum to make the tip of the chip into a single-crystal grain. Then, tip 2' of the chip is made smooth and hemispherical to less than 1mum, by heating under vacuum or in inert gas. After the above-mentioned shaping, a high-temperature heat treatment is carried out in hydrocarbon gas to obtain the carbide field emitter with carbide metal single crystal (a) at tip part 2. The field emitter obtained in this way is low in work function and the chip tip emitting electrons is a smooth hemisphere of less then 1mum in curvature radius, so that the reproducibility of the directional distribution of emitted electrons will be excellent.

Title: Counting method of cleaning body
Inventor: MUKAI YASUAKI
IPC: B08B9/053
Filed: 1985-03-06
Abstract: PURPOSE:To provide a method that can accurately count the number of cleaning bodies by determining the number of cleaning bodies that have passed by comparing two kinds of threshold voltage values of the threshold voltage value of the start of passage of a cleaning body and the threshold voltage value of the completion of passage of a cleaning body with the voltage value at the time of the cleaning body passage. CONSTITUTION:The ultrasonic wave passing through the cleaning body flow passage 1 is inputted as an amplified signal to an arithmetic unit 10 for counting the number of cleaning bodies 2 via a judgment unit 7. The judgement unit 7 determines that one cleaning body has passed based on the threshold voltage value of the start of passage of cleaning body and the threshold voltage value of the completion of passage of cleaning body. The ratio between the threshold voltage value of the start of passage of cleaning body and the voltage value only for water passage is set at 0.29 or more which satisfies the ratio between the voltage value at the time of the cleaning body passage and the voltage value only for water passage, but less than 0.53 which satisfies the value obtained by subtracting the ratio between the value of voltage fluctuation due to the noise and the voltage value of water passage only from the ratio between the voltage value of bubble and dust passage and the voltage value of water passage only. In this manner, erroneous counting due to the variance of ultrasonic wave damping through the cleaning body and erroneous counting due to the presence of bubbles and dusts in the fluid can be prevented.
