Title: Electrolytic grinding method for non-conductor
Inventor: KUROMATSU AKIO
IPC: B28D1/00
Filed: 1981-06-24
Abstract: PURPOSE:To perform at high speed melting of the material and exfoliation of the molten part in such a way that when performing electrolytic grinding in use of an electric conductive grinding stone, mechanical grinding and electrolytic grinding are alternately worked by applying alternating current to a non-conductive material. CONSTITUTION:An electrode is connected to a non-conductive material M to be ground as well as to a grinding stone 1 from a voltage feeder E. Next to it, the grinding stone 1 is rotated at high speed, the voltage feeder E is energized, and wave-form alternating current voltage is applied. Therefore, electric conductive condition is generated by dielectric action between an electric conductive material 10 which has been embedded in the end curved face of the grinding stone 1 and a non-conductive material M, melting of the material M goes ahead, and then mechanical grinding action goes ahead with particles on a grinding belt 11. Since these both actions are alternately repeated for a short time, the molten part is mechanically exfoliated and removed forthwith, so that exceedingly efficient grinding can be performed.

Title: Production of phenylcarbonyl compound
Inventor: EDA TSUNETO
IPC: C07B61/00
Filed: 1993-03-30
Abstract: PURPOSE:To obtain the subject compound in a high purity and yield by simple operations comprising only reacting an aluminum halide with a carbonyl chloride compound in a solvent-free state and subsequently reacting the produced addition compound with a benzene derivative in a solvent-free state. CONSTITUTION:An aluminum halide is reacted with a carbonyl halide of formula I (R2 is 1-5C alkyl; X is halogen) in a solvent-free state, and the produced addition product is reacted with a benzene derivative of formula II (R1 is H, 1-5C alkyl) in a solvent-free state to provide a phenyl carbonyl compound of formula III (e.g. 4'-ethylpropiophenone). The method is advantageous because of not using a specific solvent and of not requiring to maintain the reaction temperature at a low temperature. The phenylcarbonyl compound of formula III is useful as a raw material for perfumes, medicines, etc.

Abstract: PURPOSE:To improve the durability of a disk by providing a degree of freedom for the vertical motion for both two magnetic heads clipping one magnetic disk, providing the degree of freedom to the one head for pitching or rolling, and supporting tightly the other head. CONSTITUTION:The magnetic heads 1, 6 are arranged to both sides of a flexible magnetic disk 14. The head 1 is supported by a gimbal 7 having the degree of freedom of motion in the pitching/rolling direction, the gimbals 7 is fitted to a rotary arm 2 and the arm 2 is fixed to a plate spring 3 by a screw 4. A pivot 9 is in contact with the rear face of the gimbals 7 to receive the degree of freedom while being supported by the rigidity of the spring 3 in vertical direction and has no effect by the gimbals 7. The head 6 is fixed directly to the rotary arm 8 being a rigid body fixed to the plate spring 10 by a screw 11. The head 6 is supported elastically by the plate spring 10 in vertical direction, and since the freedom of vertical motion is given but has a large rigidity against the pitching/rolling direction, the head 6 is hardly moved against deflection of the disk 14 or external vibration.

Abstract: PURPOSE: To make possible the continuous production of products which are likely to cause misrun defects, stably without any defect by making molds and the suction box communicated with an evacuating device contactable and detachable with and from the top and under of suction holes, in the predetermined stop positions of a rotary table with plural suction holes.  
     CONSTITUTION: To cast products, such as those having exceedingly thin and sharp edges, which are likely to cause misrun defects, a plurality of molds conforming to product shapes are prepared. The preheated first mold 14 is placed on a suction hole 6a and a rotary table 1 is rotated 60° to move the first mold 14 to the position B. Thereupon, a suction box 18 is moved upward until it closely contacts the bottom surface of the table 1, after which molten metal is poured into the mold. At the same time, suction casting is performed by a suction device 27. After the predetermined time, atmospheric pressure is restored in the box 18 to detach the box from the bottom surface. During this time, the next mold is placed on the suction hole 6f in a similar manner and the table 1 is rotated 60° intermittently to move the first mold to the position C of the cooling zone and the next mold to the position B. Thereafter, the casting is continuously repeated in the same manner.

Title: Correcting device for grinding wheel shape of spherical grinding machine
Inventor: KONDO JOTARO
IPC: B24B53/08
Filed: 1990-04-12
Abstract: PURPOSE:To automatically perform the shaping of the edge of a cup like grindstone, by providing a circular movement command mean which controls Z axial motor and X axial motor with their linkage and moves a grindstone unit along the circular arc locus. CONSTITUTION:A numerical control (NC) device 7 indicates a dress motion whenever the grinding in the specific quantity is performed. When this dress motion is indicated, the NC device 7 moves the edge 1a of a cup like grindstone 1 to the tip position of a dress grindstone 11 by driving X axial motor 6 and Z axial motor 5 and advances it in the Z axial direction further by the specific radial feed quantity DELTAt. A circular arc motion is then performed by a grindstone unit 3 with a circular movement command mean 21. Meanwhile, the dress grindstone 11 and cup like grindstone 1 are driven with their rotation. The NC device 7 returns the cup like grindstone 1 to the original position by driving the Z axial motor 5 and X axial motor 6. Consequently once dress motion is completed and the cup like grindstone 1 is shifted to the processing of a work.

Title: Bonding wire for semiconductor element
Inventor: HAYASHI SHIYOUZOU
IPC: H01L23/49
Filed: 1979-07-30
Abstract: PURPOSE:To obtain a high quality junction wire by coating a high purity Ag wire with high purity Au or alloys adding Be, Ca, Co, Fe, Ge, Ni or one group of Pd, Pt, Rb, Ir, Os, Ru or elements out of both groups to Au. CONSTITUTION:Ag and Au of 99.99W/O or more are easily alloyed and have good break strength and metallic wires composing of the above Ag and Au will not peel off at the time of junction. The sulfuration of Ag will also be prevented by Au coating. If the gross amount, about 0.0003-0.01W/O, out of Be, Ca, Co, Fe, Ni is added to Au, mechanical strength will further be increased. The amount of 0.0003-0.01W/O, or less will have no effect and that of 0.01W/O or more will have inferior junction. Pd, Pt, Rh, Ir, Os, Ru also adapt well themselves to Au or Ag. Therefore, 0.0003-0.1W/O in gross amount out of them may be added to Au or Ag to increase the mechanical strength. The amount of 0.0003W/O or less will have no effect and the slip of wire is not good for the amount of 0.1W/O or more. When addition is made from both groups, about 0.0003-0.11W/O in total amount will be suitable.
