Title: Magnetic recording medium
Inventor: FURUYA NOBUAKI
IPC: G11B5/73
Filed: 1985-06-18
Abstract: PURPOSE:To orient the axis of easy magnetization direction of a magnetic layer in the direction different from the circumferential direction of a wire- shaped core wire consisting of a non-magnetic material by forming the thin magnetic layer of a magnetic material on the surface of the core wire. CONSTITUTION:The core wire 1 is formed of the non-magnetic material having high tensile strength to a wire shape. The magnetic layer 2 made of the thin film formed on the outside periphery of the core wire 1 is so set as to be made thinner than the diameter of the core wire 1. The axis of easy magnetization direction 3 is directed toward the axial direction of the core wire 1. Since the axis of easy magnetization 3 is in the axial direction of the core wire, the recorded magnetization 4 faces forward and backward in the axial direction and therefore a magnetic flux 5 emits to the outside of a magnetic recording medium. This magnetic flux 5 can be reproduced by the magnetic head to an electric signal by utilizing said magnetic flux. Since the magnetic layer 2 is relatively thinner than the diameter of the core wire, the diamagnetizing field by the thickness of the magnetic layer is less and the high recording density is obtd. in the axial direction.

Filed: 1977-11-05
Abstract: PURPOSE: To provide a bicycle wheel which enables a simple assembly with a hub into which a shaft penetrates and production with an excellent yield because of less loss of material in punching a plurality of arms out from a sheet of band-shaped metal.  
     CONSTITUTION: A base plate 1 having a plurality of arms 2 connected to one another at the root thereof is so punched out from one sheet of metal as to form a comb shape as a whole.

Title: Branch connecting terminal for cable
Inventor: MUNEMASA YOSHIHITO
IPC: H02G15/08
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of strains in the attaching surface of an attaching section when a cylindrical press-fitting section is compressed, by integrally forming the section between part of the cylindrical external side face of the press-fitting section and the attaching section through a connecting section which is more constricted than both end faces of the press-fitting section. SOLUTION: A connecting section 2c has constricted parts 2h formed of hollows from the top and bottom sides. Therefore, the thickness A of the section 2c in the vertical direction is smaller than the thicknesses L of both ends faces of a cylindrical press-fitting section 2a. The twisted conductor of a flat-type cable and the conductor of a branch line are press-fitted to the press-fitting section 2a by compressing the press-fitting section 2a from both the left and right sides. When the conductors are press-fitted to the section 2a, the stresses generated in the section 2a are hardly transmitted to the fitting section 2b, because the stresses are concentrated to the constricted part 2h. Since the flat attaching surface of the attaching section 2b is strained, the possibility of the attaching surface of a circuit breaker being positioned unstably is eliminated.

Title: Pulse width control current resonance converter
Inventor: ZAITSU TOSHIYUKI
IPC: H02M3/155
Filed: 1989-05-26
Abstract: PURPOSE:To enable such pulse width control operation as the switching duty ratio is varied while maintaining constant switching period by inserting a movable core into a core gap through a piezoelectric actuator thereby varying the inductance of resonance coil. CONSTITUTION:Control circuit 14 for a switching circuit 6 raises the gate voltage of a switching transistor 12 with preset period T and switches the source- drain of the transistor 12 to ON state. Consequently, sinusoidal resonance current flows through a coil 8. A current detector 13 detects the zero reset timing of resonance current and pulls down the output voltage from the control circuit 14. A waveform having low duty ratio is obtained under a state where the resonance frequency of resonance circuit is high while a waveform having high duty ratio is obtained under a state where the resonance frequency is low. Output voltage from a smoothing circuit varies according to the value of duty ratio.

Title: Fine positioning mechanism
Inventor: NAKAMURA TERUHIRO
IPC: B23Q5/34
Filed: 1987-05-29
Abstract: PURPOSE:To improve positioning accuracy while to variably obtain resolving power by constituting a mechanism converting rotation of a feed screw into the fine movement of a wedge member and the movement of the wedge member further into the fine movement of a load shaft which moves sliding along a can part of that wedge member. CONSTITUTION:A rotary driving mechanism 8, which rotates a feed screw 7 in a predetermined direction, converts a rotary angle of the feed screw 7 into the fine movement of a slide 3 moving it sliding in a direction A. Then a load shaft 12, whose end face comes into slide contact with a cam surface 4, moves sliding in a direction C against tension of a coil spring 13. While the load shaft 12, when the slide 3 is moved sliding in a direction B, moves sliding in a direction D by the tension of the coil spring 13. Here setting an angle, formed by the cam surface 4 with respect to its sliding direction, to a degree smaller than 45 deg., the movement of the slide 3 is converted into further fine movement of the load shaft 12. Accordingly, a work bed substantially improves its positioning accuracy because of very small resolving power while because of no backlash.

Filed: 1984-06-28
Abstract: PURPOSE:To easily measure a high voltage and to improve the precision of the measurement by coating a single-mode optical fiber with piezoelectric ceramics, and measuring a voltage on the basis of the phase shift of light transmitted through the coating part. CONSTITUTION:A detection part 13 is placed in an electric field established around an electric conductor 5 so that the axial direction of the detection part 13 coincides with the electric field direction. Distance (d) is determined previously by experiments. When a voltage is applied to an insulator string 3, the electric field is produced around the electric conductor 5 and the piezoelectric ceramics 12 has piezoelectric effect to strain the detection part 13 axially. Consequently, detected light L2 and reference light L3 have a mutual phase shift and output light L4 decreases in quantity. Consequently, the signal S of an amplifying circuit 26 increases in level and the value of the voltage applied to the insulator string 3 is displayed on a display meter 27 to read the applied voltage directly. Consequently, the measuring operation is facilitated and a measurement with high precision is taken.
