Title: Grinding wheel
Inventor: IMAI TOMOYASU
IPC: B24D5/06
Filed: 1986-12-25
Abstract: PURPOSE:To prevent a chatter from occurring on the outer face of a work by forming attaching faces inclined to the radial direction of a grinding wheel on the faces of a grindstone piece faced to each other and fixing the grindstone piece to the outer periphery of a core, and attaching the attaching faces with an adhesive. CONSTITUTION:A grindstone piece 20 is molded so that the shape viewed from the side becomes nearly a parallelogram. Grindstone pieces 20 are aligned in a line on the outer periphery of a core 10 so that attaching faces 21 are faced to each other in parallel. Under this condition, the inner face 22 of the grindstone piece 20 is attached to the outer periphery of the core 10 and the attaching faces 21 are attached to each other with an adhesive 30. According to this constitution, when a work is ground and machined, a rough 50 is generated near the adhesive 30 on the outer face of the grindstone piece 20. However, the outer diameter of a grinding wheel 40 is shrunk at every grinding, as a result, the position of the adhesive 30 is displaced in the peripheral direction of the grinding wheel 40, thus the rough 50 does not progress, and no chatter occurs on the outer face of the work as an advantage.

Title: Cable end
Inventor: NIINOBE HIROSHI
IPC: H02G15/064
Filed: 1990-11-19
Abstract: PURPOSE:To obtain a cable end which makes it possible to monitor compressive force against a premolded insulator, without breaking up the cable ends, even when the compressive force is uneven, by providing a pressure sensor at the contact surface of the first flange with the second one, and by detecting pressing force by a coil spring with the pressure sensor. CONSTITUTION:A flange 9 is put between a coil spring 4 and a flange 5, and a pressure sensor 14 is provided at the contact surface of the flange 9 with the flange 5. Then, the compressive force against a premolded insulator 2 through the pressing metal fittings 3 of the coil spring 4 is received by the flange 9. Hereupon, the undersurface of the flange 5 touches a position setting nut 13 and is supported by it. As a result of this, the compressive force against the premolded insulator 2 is detected by the pressure sensor 14. And this makes it possible to judge the compressive force against the premolded insulator 2 precisely by the pressure sensor 14, even when surface pressure becomes uneven owing to the so-called insufficient centering of the cable.

Title: Magneto-optical recording medium
Inventor: TABATA MASAHIRO
IPC: G11B11/10
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To enhance a recording characteristic by providing a second magnetic thin film which is a transition metal dominate film for controlling a magnetic characteristic generated by the exchange coupling force of the exchange interaction between a first and a third magnetic thin films in the middle between the first and the third magnetic thin films. SOLUTION: This magneto-optical recording medium 1 has a second magnetic thin film 5 for controlling surface magnetic wall energy in the middle between a first and a third magnetic thin film 4, 6. By making the composition of the thin film transition metal dominate, magnetic wall energy can be lowered in the vicinity of a room temperature and increased in the vicinity of a temperature T1 . Therefore, the surface magnetic wall energy at a room temperature can be stabilized, and the stability of transfer in a recording magnetic domain can be enhanced in the vicinity of the temperature T1 . On the other hand, since a recording magnetic field acts in the direction of obstructing the reversal of the thin film 4, stability with respect to the change of the recording magnetic field is enhanced by using the transition metal dominate film for the thin film 5.  Therefore, the medium 1 ensures light modulation direct over light.
