Title: Preventing mechanism for brake noise
Inventor: MASUOKA KENPACHI
IPC: F16D65/00
Filed: 1981-11-04
Abstract: PURPOSE:To enable maintaining of a steady and high level vibration attenuation in a wide temperature range, by a method wherein a brake noise proofing mechanism, including a plurality of a plastic resin layers being different in vibration attenuation-temperature properties, is cladded to a backing of a friction pad. CONSTITUTION:Laminal polypropylene P and polyvinyl chloride e, which are sticked together, are adhered to a backing 2 of a friction pad 1. Attenuation properties of a member E, in which only the polyvinyl chloride is adhered between the nip formed by steel plates, is maximized at about 60 deg.C, and decreases at a temperature of higher than 60 deg.C. The member P, in which only the polypropylene is adhered between the nip formed by the steel plates, is high in a heat resistant temperature, and therefore, it is excellent in the attenuation properties at a high-temperature range. If attenuation of, for example, a shim A is represented by a loss factor, it is about 4-6-fold a shim B of a conventional product, and besides, a steady attenuation may be maintained in a range of from a low temperature to a high temperature.

Title: Contact type thickness gauge for moving sheet material
Inventor: PETSUKA EMU TEITSUPO
IPC: G01B/
Filed: 1988-07-15
Abstract: PURPOSE: To measure the thickness of a moving sheet by setting the cross-section of one leg of a U-shaped pole piece significantly smaller that of the other leg and bringing the leg having smaller cross-section into contact with the sheet while separating the leg having larger cross-section from the sheet. CONSTITUTION: The area A1 of one leg 22 of a U-shaped pole piece 21 is set significantly smaller that A2 of the other leg 23. The gap between the leg 22 and a slab 24 is set equal to the thickness (d) of a sheet 10 so that the leg 22 comes into contact with the moving sheet 10 constantly. The gap between the leg 23 and slab 24 is set equal to the gap (d) plus an additional air gap d0 so that noncontact state is kept between the leg 23 and the sheet 10. Windings L1 , L2 on the legs 22, 23 form a resonance circuit having a resonance frequency substantially dependent on the mutual inductance M of windings L1 , L2 and independent from the stray inductance of the winding itself. The resonance frequency represents the variation of gap and since it is proportional to the thickness of sheet 10, the thickness of sheet 10 can be measured.  Furthermore, scratching of the sheet can be minimized because only the leg 22 having small area comes into contact with the sheet.

Title: Optical head
Inventor: IKEGAME TETSUO
IPC: G11B7/08
Filed: 1991-07-17
Abstract: PURPOSE:To provide an optical head whose optical axis is not inclined even when a movable part is moved. CONSTITUTION:The movable part 12 consists of a lens 1 and its holding holder 2, a tracking and a focusing coils 3, 4 for driving. The movable part 12 and a fixing member 6 are connected with a spring 5. The fixed end 5c of the holder 2 side of the spring 5 is shifted by a distance (m) in an opposite direction from the fixing member 6 to the gravity G of the movable part 12. In such a case, when the movable part 12 is moved to a Z direction the force inclining to the fixing member 6 side and the force inclining to the opposite side from the fixing member 6 are generated to the mobile part 12. Thus, these both forces are compensated with each other, the optical axis of the lens 1 is not inclined since the movable part 12 is not inclined.
