Abstract: PURPOSE:To enable determination of an angular velocity by a simple approximate computation, by conducting division by using the value of a harmonic component of an even-number order at the time when the harmonic component is smaller than a threshold value just before a harmonic component of an odd-number order, when this component is larger than the threshold value. CONSTITUTION:An optical fiber 5 has a part constituting a sensor coil 6 and a part wherein a phase modulation element 7 is provided. A light-emitting element 1 generates a coherent light and a light branch element 2 splits a light from the element 1 or a light sent from the element 1 through the optical fiber 5 and supplies it to the opposite ends of the optical fiber 5. A light-sensing element 9 senses the light emitted from the opposite ends of the optical fiber 5 and coupled by the element 2. A synchronous detector 13 detects a harmonic component (containing a fundamental wave) P2m+1 of an odd-number order of a phase- modulated frequency, while a quadruple harmonic detecting element 15 detects a harmonic T2n of an even-number order of the phase-modulated frequency. A divider 14 divides the component P2m+1 by the component T2n and outputs the quotient S thereof. The division is executed by using the value of the component T2n at that time when the component P2m+1 is smaller than a threshold value Pf, and by using the value of the component T2n just before the component P2m+1 and at the time when the component P2m+1 is smaller than the threshold value Pf, when this component is larger than the threshold value.

Title: Cushioning material for multistage stacked package
Inventor: AOKI SATOSHI
IPC: B65D81/113
Filed: 1989-11-13
Abstract: PURPOSE:To make acceleration which is applied to packaged objects smaller and prevent damage of the packaged objects from happening by a method wherein the lower surface part of an upper storage recessed part which a packaged object comes into contact with is made not to correspond with the upper surface part of a lower storage recessed part which a packaged object comes into contact with. CONSTITUTION:For the title cushioning material, a recessed part 5 which is provided on the lower surface of an upper storage recessed part 2 and a protruding part 6 which is provided on the upper surface of a lower storage recessed part 3, i.e., a part which corresponds with the recessed part 5 are formed. Thus, the lower surface part on the upper storage recessed part 2 which a magnetron 4 comes into contact with, i.e., the part where the recessed part 5 is not provided, does not correspond with the upper surface part of the lower storage recessed part 3 which a magnetron 4 comes into contact with, i.e., the part where the protruding part 6 is provided. Therefore, when the magnetrons 4 are transported using this cushioning material, even if vibration with a frequency of approximately 10Hz is applied, the magnetrons 4 do not mutually hit the same part of the cushioning material for multistage stacked package. By this method, acceleration which is applied to the magnetrons 4 can be made small, and damage of the magnetrons 4 is prevented from happening.

Title: Magnetic head slider for contact recording and its manufacture
Inventor: SATO YOSHIHIRO
IPC: G11B21/21
Filed: 1994-11-28
Abstract: PURPOSE: To obtain a highly reliable magnetic head slider with a decrease in friction force by providing a carbon protecting film having fluorine ions injected onto a sliding face of the magnetic head slider. CONSTITUTION: An Si film 1b and a C film 1a as a sliding protecting film are formed respectively 5nm thick and 20nm thick by sputtering on a surface of an Al2 O3 TiC slider substrate 4 facing a disc. Thereafter, CF4 gas is subjected to ion separation thereby to inject fluorine ions into the C film 1b at a voltage of 10KV. The surface roughness is increased and the formation of a lyophobic surface is facilitated because the fluorine ions are injected into the C film 1b as the sliding protecting film, and consequently the shear strength of an interface to a lubricant on the magnetic disc is eased. The friction force is accordingly decreased. Moreover, the abrasion is reduced, so that a highly reliable slider is obtained.
