Title: Manufacture of ferrite carrier for electrostatic copying
Inventor: KOSAKA TOMOYOSHI
IPC: G03G9/107
Filed: 1984-08-13
Abstract: PURPOSE:To obtain the titled carrier excellent in surface properties and hardly deteriorative in characteristics from the initial period by heat-treating an Mg- Zn ferrite carrier in the reductive atmosphere and forming a low electrical insulating surface layer thereon. CONSTITUTION:An Mg-Zn ferrite carrier having the composition 50-65% (by mol%) Fe2O3, 10-30% MgO, 5-30% ZnO, <=5% MnO and 1-5% CuO is heat- treated in the reductive atmosphere. Thereby a layer low in electrical resistance is formed on the surface of spherical carrier particles. Therefore a little of the toner electrification due to the frictional electrification is caused and the toner is easily transferred to the latent image and the solid black characteristics and the surface properties are excellent. A maintenance-free copying machine can be realized wherein those advantages are combined and the deterioration of developer is hardly caused by the repeated copying for a long period and the maintenance is unnecessitated.

Title: Cartridge for video disk player
Inventor: TAMURA SHINGO
IPC: G11B17/32
Filed: 1983-09-16
Abstract: PURPOSE:To improve the follow-up performance of a cartridge and to attain the reproduction of a disk having large surface vibrations, by supplying the pressure given to the stylus tip to the force produced by a flay lead, then adding the force produced by the repulsive force of a kicker magnet to said force of the fly lead. CONSTITUTION:A permanent magnet 14 is set at an upper part (opposite to a disk surface) of a kicker magnet 6 with magnetic poles of same types put opposite to each other. With addition of the magnet 14, the magnet 6 is repulsed downward by the force FM of the magnet 14. This force FM is transmitted to the stylus tip to serve as a part of the stylus pressure. The force FM is adversely proportional to the distance between the magnets 14 and 6. While the spring force produced by a fly lead 7 is set to a curve 16. That is, the slope of a stylus curve is reduced at the side (a range l>l0) lower than the prescribed position of the disk. Thus the allowable surface amplitude value is increased for the disk.

Title: Manufacture of hollow stock having twisted part
Inventor: ITABASHI KAZUHIRO
IPC: B21C23/08
Filed: 1992-06-26
Abstract: PURPOSE:To extrude a hollow stock having a twisted part so that a joining line is not generated on it by forming a twisted part inclined more closely to the side of the central axis line of a die by a specified angular range than the twisted part of a bearing part in a material introducing part formed on the die. CONSTITUTION:The twisted part 15a of a material introducing part 15 inclines more closely to the central axis line of the die 13 by a range of 1-30 deg. than the twisted part 14a of the bearing part 14. Consequently, before billet B enters the bearing part 14, it moves while it describes a spiral locus along the twisted part 15a formed in the material introducing part 15. The material introducing part 15 is larger in diameter than the bearing part 14. The billet B is more gently pressed at the material introducing part 15 compared with the case when it enters directly the bearing part 14. The billet B entering the material introducing part 15 abuts on the twisted part 15a of the material introducing part 15, it moves spirally with an angle of torsion equal to an angle of torsion of the twisted part and the billet B changes its direction smoothly and moves.

Title: Parabolic antenna
Inventor: FUKUZAWA KEIJI
IPC: H01Q19/12
Filed: 1991-06-14
Abstract: PURPOSE:To improve the directivity, to surely receive a radio wave from a desired broadcast satellite and to prevent the deterioration in the cross polarized characteristic by selecting a reflecting plate to have an elliptic aperture and selecting a feed horn to be a dual mode horn. CONSTITUTION:A reflecting plate 12 is formed to be an elliptic aperture long in the lateral direction, a feed horn 13 is selected to be an elliptic aperture long in the longitudinal direction and they are formed to be a dual mode horn. When the reflecting plate 12 is selected to be an elliptic aperture long in the lateral direction, the directivity in the horizontal direction is made sharp and since the directivity in the vertical direction is relatively broader, the feed horn 13 into which a radio wave reflected in the reflecting plate 12 is made incident is selected to be an elliptic aperture having the major axis in the vertical direction. Furthermore, since a circularly polarized wave cannot be converted efficiently into an electric signal, the circularly polarized wave is converted into a linearly polarized wave. Thus, a radio wave from a desired broadcast satellite is surely received.

IPC: H01L49/02
Filed: 1981-10-22
Abstract: PURPOSE:To reduce the variety of complicated masks to be required to only one type by minimizing over-etching of a heating part in a heat generating resistor pattern by etching off an unnecessary part of an electrode film and a heat generating resistor film after the etching off of the electrode film in a belt. CONSTITUTION:A belt-like resist pattern 15 including a region intended for an electrode pattern is formed on a multilayered film having a tantalum nitride film 5, a nichrome film 6 and a gold film 7 lengthwise of a thermal head. With this pattern as mask, the gold film 7 and the nichrome film 6 are etched sequentially and then, the residual resist pattern 15 is peeled away. Again, a resist pattern 16 is formed covering the electrode pattern and a heat generating resistor pattern and used as mask to etch the gold film 7, the nichrome film 6 and the tantalum film 5 sequentially. Thus, a tantalum nitride film pattern (heat generating resistor pattern 1), a part directly contacting the resist pattern, is little affected by over-etching.

Title: Production of hydrogen
Inventor: OOTA MASAO
IPC: B01J23/00
Filed: 1980-12-04
Abstract: PURPOSE: To inexpensively produce high purity hydrogen at a relatively low temp. by bringing a reducing gas contg. CO or hydrocarbon into contact with a substance prepared by adding a Pt group element to a transition metallic oxide and bringing steam into contact with the substance.  
     CONSTITUTION: A reducing gas contg.CO or hydrocarbon is brought into contact with a substance prepared by adding a Pt group element to ≥1 kind of transition metallic oxide selected from Mo, W, V, U, Fe and Ni oxides. The substance after the contact with the reducing gas is then brought into contact with steam to generate gaseous hydrogen. When the gas as starting material contains oxygen and steam, the reaction yield is lowered. Accordingly, when the hindering components are contained in the treating gas, it is preferable to remove them in a pretreatment process. Since such a highly active catalyst is used in this method, the preferred reaction temp. of the process is 300W500°C.

Abstract: PURPOSE: To prevent the gas blow-out at the end period of tapping and control the outlow speed of molten steel slag by inserting the discharge end of the tap hole nozzle mounted to the iron notch of a blast furnace into a freely elevatable seal pot.  
     CONSTITUTION: A tap hole nozzle 10 is freely attachably and detachably mounted  to an iron notch 2, and a seal port 11 is inserted into the discharge port at the  bottom end thereof. An emergency spout 14 is provided below the iron notch 2.  When the molten iron slag level in the furnace lowers down to the level of the iron  notch 2, a hydraulic cylinder 12 is operated to move the seal pot 11 upward in such  a manner that the head H of the steel pot rises to more than the in-furnace pressure, thereby stopping the outflow of the molten iron slag. When the molten iron  slag level returns to more than the level of the iron notch 2, the outflow of the  molten iron slag is automatically resumed by the difference in the molten metal  level between the inside of the furnace and the steel pot 11. The outflow speed of  the molten iron slag is freely controlled by vertically moving the position of th seal  pot 11 thereby changing the immersion depth of the tap hole nozzle 10.
