Title: Shared antenna
Inventor: SUGURO AKIHIRO
IPC: H01Q5/10
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a compact and highly sensitive shared antenna which is suitable to both satellite communication and terrestrial communication by properly placing a microstrip line planar antenna and a helical antenna. SOLUTION: A helical antenna 9 is obtained by winding a conductor 8 around a dielectric cylinder 7 with a fixed pitch. A coaxial wire 13 is led through the center axis of the cylinder of the antenna 9 to feed a microstrip line planar antenna 6 of a back-to-back feed system. Then the antenna 6 is placed above the antenna 9. A feed pin 1 of the antenna 6 receives the power via a center conductor 12 of the wire 13, and the power is supplied to the antenna 9 via the lower edge of the antenna 9 and a ground plate 4. A portable telephone set is provided with a switch to select either antennas 6 and 9 and operates separately between the frequency f1 and f2.  In other words, the satellite communication is performed with a satellite by the circularly polarized wave through the antenna 6 and the terrestrial communication is performed with a ground base station by the linearly polarized wave through the antenna 9 respectively.

Title: Structure of mold variable in size of cast slab
Inventor: TANAKA SHIGENORI
IPC: B22D11/05
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To facilitate the arrangement of a driving device for divided molds by slidingly shifting the divided molds to mutually vertical direction along inclined flat cutting surface. SOLUTION: The mold 1 is combined with a right side divided mold 2 and a left side divided mold 2 divided with the inclined flat cutting surface 1 directed from the upper end part to the lower end part. In order to form to small inner hole width, e.g. the divided mold 3 is slidingly shifted downward to the other divided mold 2 along the cutting surface 1. By this slidingly shifting, the width of inner hole of the mold is changed from W1 to W2 and as a result, the width of a cast slab becomes small size. Further, the divided mold 2 and the divided mold 3 are brought into close contact with the cutting surfaces 1 and the cutting surface 1 at the time of casting is not brought into contact with molten metal.  Therefore, on the cutting surface 1, the wearing and the deformation are not developed and thus, the divided mold 2 and the divided mold 3 are always sufficiently combined in the close contacting condition. By this constitution, the penetration of the molten metal, etc., in the combined part is not developed. Further, the sound cast slab can be obtd. because of no development of the penetration of the molten metal.

Abstract: PURPOSE:To automatize the captioned device without making it large-size by rotating a movable frame after allowing it to pass through a first work on a conveyance path, to switch the path to a second work path, and then opening the first work path, and further repeating these operations alternately. CONSTITUTION:An R member placed on a belt conveyer passes through a fixed frame 4, a movable frame 5, and a stopper 6, and falls onto a chute 7. Thereupon, a photoelectric switch 16 detects the R member and enters the signal into a controller 17. The controller 17 actuates a cylinder 12 to lift the stopper 6 for stopping an L member, and in succession actuates a cylinder 8 to permit the movable frame 5 to decline for allowing the L member to fall onto a chute 15. Then, the cylinders 12, 8 are restored to return to the side of allowing the R member to pass. These operations are alternately repeated. Such arrangement automatizes the captioned device with a simplified and miniaturized structure.

Title: Controlling device for positioning magnetic head
Inventor: INADA HIROSHI
IPC: G11B21/10
Filed: 1985-11-13
Abstract: PURPOSE:To accurately position a magnetic head by applying positioning control to a magnetic head onto a track based on position information recorded in advance at a prescribed interval in the turning direction of a disc. CONSTITUTION:A track position error signal from a magnetic head 7 is inputted to a sample-holding circuit 9, where the signal is sample-held at a prescribed time interval. The result is added simultaneously to a signal sample-held precedingly to generate the stepwise track position error signal. The error signal is added as an offset signal of a carriage position error signal by an adder 10 of a carriage position control circuit. Thus, in setting the carriage position error signal and the stepwise track position error signal with respect to the position gain equally, the carriage follows the stepwise track position error signal. Then the magnetic head 7 mounted on the carriage is operated similarly as the carriage to trace the object track accurately.

Title: Plastic magnetic molding and rotor using it
Inventor: ITO AKIHIRO
IPC: H01F1/08
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To improve the mechanical strength of a plastic magnetic molded piece and make the press-fitting width for a rotor using it to be larger. SOLUTION: A plastic magnet molding is formed plastic magnet molded material to which a reinforcing material made of carbon fiber or glass fiber, etc., in addition to magnetic powder and resin binder is added, so as to improve its mechanical strength. The addition of the reinforcing material causes a slight decrease in its magnetic property, hoever, when a magnetic powder with high magnetic property containing rare-earth metal and Co is used therefor, it hardly gives any influence to devices. After rotor magnetic 1 which is cylindrical substantially by using a plastic magnet molding is molded, a central shaft 2 is press-fitted into a central hole so as to form a rotor. At this time, any cracking due to press-fitting, especially cracking in an anisotropic direction in case of an anisotropic magnetic is hardly generated, so that the press-fitting width can be made smaller and its slip torque be also made larger.
