Title: Composite magnetic head
Inventor: KEN SOUJITSU
IPC: G11B5/187
Filed: 1993-06-16
Abstract: PURPOSE: To efficiently suppress the generation of ripple phenomenon by making the first magnetic core member forming a main gap parallel and making a second magnetic core member forming a sub-gap asymmetrical. CONSTITUTION: A face for forming the ferromagnetic metallic thin film 106 of the first magnetic core member 102 parallels a surface for forming a magnetic gap G and a face for forming the ferromagnetic metallic thin film 108 of the second magnetic core member 104 is formed at a prescribed angle with respect to the surface for forming the magnetic gap G. Thus, at the time of recording/reproducing a magnetic tape by a magnetic head 100, the main gap is generated by the metallic thin film of the first member 102 and the sub-gap is generated by the metallic thin film 108 of the second member 104. Consequently, a ripple signal generated at the member 104 at the time of recording/ reproducing a signal to a tape by means of a magnetic head 100 is superpose- recorded to the main gap from a step before the main gap depending on the advancing direction of the tape and a ripple signal recorded from the step next to the main gap is erased by the main gap so that the generation of the ripple phenomenon is perfectly eliminated.

Title: Permanent cylinder magnet
Inventor: OKONOGI ITARU
IPC: H01F41/02
Filed: 1982-08-20
Abstract: PURPOSE:To enable mass production of a stable permanent cylinder magnet, by a method wherein a mixture mainly consisting of rare-earth cobalt strong magnetic powder with magnetic anisotropy and resin is put in a mold, and magnet field is impressed and orientated on the mold in the diameter direction of the cylinder magnet. CONSTITUTION:A mixture is made by rare-earth metal compound powder with magnetic anisotropy, such as Sm and Y, and the strong magnetic metal such as Co and Mn, as well as by the strong magnetic alloyed powder such as SmCo5 consisting of transition metal such as Si and W, epoxy resin, polyamido resin, and phenol resin. The mixture is put into a mold and magnetic field is impressed and orientated onthe mold in the diameter direction of the cylinder magnet by using a magnetizer. The powder must be moved freely in the mold. Then pressure is applied in the right angle directin to the diameter to solidify the mixture. Thus, mass producton of the magnet with stable quality is made possible, with neither crack nor deformation.

Filed: 1982-08-23
Abstract: PURPOSE:To reduce the loss time of work and to reduce the cost of an NC device by forming an ND data processor which is attachable to and detachable from the NC device frame. CONSTITUTION:The NC data processor 14 is equipped with a CPU18, keyboard 20, display device 22, memory 24, etc., to perform processing such as the correction, editing, etc., of NC data.

Title: Rubber vulcanization molding process
Inventor: OTAKA HIDENORI
IPC: B29C33/02
Filed: 1989-06-08
Abstract: PURPOSE:To warm up unvulcanized rubber uniformly by using a core of heat pipe structure and inject the unvulcanized rubber to a hollow section and then heat vulcanizing. CONSTITUTION:A mold 1 is provided with a hollow section 2 corresponding to the outer shape of a product to be molded and an injection opening 10 for injecting unvulcanized robber or the like. A core 4 is set in the given position in the hollow section 2 of a mold 1 and the mold 1 is heated to heat vulcanize the unvulcanized rubber 30 in the hollow section 2. At that time, one end 42 adhered closely to the mold 1 of the core 4 of heat pipe structure is heated, and working fluid E is evaporated in said end section to absorb heat. On the other hand, evaporated working fluid E is transferred to the other end section 41 projecting into the hollow section 2 of the core 4 because of the pressure difference and condensed therein to discharge heat. Thus, the unvulcanized rubber 30 in the hollow section 2 is heat vulcanized by the heat from the outer peripheral section generated by heating the mold 1 and the heat from the inside of the core 4 because of the heat pipe action.

Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To improve throughput for monochrome image formation by disposing first and second developing means which develop respectively electrostatic latent images on the first and second photoreceptors with toner in the same color. SOLUTION: A first laser scanner unit(LSU) 18 and a second LSU 24 both form electrostatic latent images in the same black on a first photoreceptor 15 and a second photoreceptor 16, respectively, based on monochrome data, and they are formed into black toner images by being developed by a first black developing device 21A and a second black developing device 21B provided for the photoreceptors 15 and 16, respectively. Then, the black toner images formed on the respective photoreceptors 15 and 16 are transferred to the surface of an intermediate transfer belt 13 at the face opposite to transfer units 27 and 28. Thus, because the toner images in the same color can be formed by the use of both the first photoreceptor 15 and second photoreceptor 16 and the images in the same color can be formed at the same time, time required for the image formation can be shortened.

Title: Electrostatic chuck device
Inventor: OKANO HARUO
IPC: H01L21/683
Filed: 1981-09-17
Abstract: PURPOSE:To previously prevent an induction material from rotation or movement in the gravity direction by a method wherein a pair of electrodes in an electrostatic chuck device are arranged so that electric line of force traversing said induction material may always be constant against the rotation or movement in the gravity direction of the induction material. CONSTITUTION:With a high voltage in about kV applied across electrodes 22a, 22b, electric line of force is emitted from the electrode 22a in a straight line and enters into a sample 24. In the event of a material with low electric resistance like a wafer S1, no electric field is generated in the sample 24, but electric line of force is emitted from the side facing to the electrode 22b and enters into  the electrode 22b in a straight line. Force in (z) direction, namely the magnitude of suction force by static electricity is proportional to the square of the applied voltage and is inversely proportional to the square of the distance as far as the sample 24. In other words, the larger applied voltage V causes the stronger attraction force and stronger adhesiveness between the sample 24 and the electrodes 22a, 22b permits chucking by strong power.

Title: Energy absorber
Inventor: TANIGAWA HISAO
IPC: B62D21/15
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To improve impact absorption capability at the early stage of deformation and to enable simplification of the production process by forming a plastic deformation inducing portions with different cross sectional shapes on a part of the extrusion directions by variable section extrusion molding. SOLUTION: Recess portions 16 are formed on outer faces of a pair of parallel side walls as a plastic deformation induction portion in the vertical direction thereof. They are made by an operation to make a supplementary dies to stick out to the inside of a dies hole of the extrusion dies while continuing extrusion operation at the time of extrusion molding using the extrusion dice. The recess portions 16 are thin, and differ in their sectional shapes in relation to the other portion of an energy absorber 10 in the extrusion direction. For instance, when an impact is applied to its longitudinal directions, stress is concentrated on both of the recess portions 16. Then a plastic deformation is induced after some elastic deformation, thereby the entire portion is plastic deformed.  This allows quick shift to the plastic deformation at the early stage of the deformation, enabling effective absorption of the impact energy. Further, molding to be conducted under the series of molding process simplifies the molding process.
