Title: Swing arm drive part
Inventor: MURAKAMI NOBORU
IPC: H02K33/18
Filed: 1993-09-27
Abstract: PURPOSE:To increase the rocking torque of a coil without extremely increasing weight of a magnet, etc. CONSTITUTION:A coil 1 rocks in the direction of an arrow 4 with a rocking shaft 3 as a center. A magnet 11 forming a magnetic field while it opposes the coil 1 is provided with a thick part 11A and a thin part 11B. Since the thick part 11A has a lower magnetic reluctance than the thin part 11B, magnetic flux is concentrated here. Since the magnetic field at a part away from the rocking shaft 3 is strong, a strong rocking torque can be obtained when the coil 1 is driven. The magnet 11 can be accurately positioned at a step part 12A of a yoke 12.

Title: Semiconductor acceleration sensor
Inventor: TANIGUCHI NAOHIRO
IPC: G01P15/12
Filed: 1993-09-27
Abstract: PURPOSE:To provide a semiconductor acceleration sensor for detecting the acceleration accurately over a wide frequency range while resisting against excessive impact or an acceleration close to oscillation frequency. CONSTITUTION:An overlapped part 3 is formed in the center of a semiconductor substrate 2 using a semiconductor fabrication technology. The overlapped part 3 is supported freely rockably with respect to the peripheral outer frame part 5 by a thin strain imparting part 4 to which a viscoelastic body 6 is attached on the surface or rear thereof. Consequently, even if the sensor part 1 is subjected to excessive impact, the viscoelastic body 6 buffers the impact applied to the strain imparting part 4 which is thereby protected against being damaged. The viscoelastic body 6 also prevents the amplitude of vibration at the overlapped part 3 from being maximized in the vicinity of resonance frequency thus improving the frequency characteristics of semiconductor acceleration sensor.

The current output beta performs common feedback connection so that it may become the source of the bias currents of the first-stage amplifiers 11-13. Thereby balanced motor driving can be carried out.

Abstract: PROBLEM TO BE SOLVED: To improve reliability in a severe environment at high temp. and humidity by laminating a magnetic film and a protective film on a substrate having a prescribed surface roughness and forming a lubricative film whose thickness is less than half the surface roughness of the protective film. SOLUTION: An underlying film 2 of Ni-P plating, an underlying film 3, a magnetic film 4, a protective film 5 and a lubricative film 6 are laminated on an Al substrate 1 supporting a magnetic medium to obtain a magnetic disk. In a magnetic disk device, the magnetic disk is fixed in a rotatable state and combined with a magnetic head slider 7 and a signal is recorded, read and written. Glass 8 or ceramic may be used as the material of the substrate 1. In order to attain high density and high capacity, the spacing between the magnetic disk and a magnetic head in the magnetic disk device is reduced, that is, the height of levitation of the head is reduced. It is therefore necessary to adopt a magnetic disk having such high flatness that the head is not crashed by contact with the disk and the average surface roughness Ra of the disk is regulated to <=2nm.  The thickness of the lubricative film 6 is regulated to less than half the surface roughness Rmax of the protective film 5.
