Title: Method and apparatus for detecting protrusion
Inventor: ITAYA MASARU
IPC: G11B5/84
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To detect the presence of a protrusion by providing a head slider arranged oppositely to the surface of a magnetic recording medium and sliding on the medium, and a pair of protrusion sensors arranged on the side face along the traveling direction of the slider. SOLUTION: Protrusion sensors 1a, 1b utilize energy the energy generated from a resistor 4 through contact with a protrusion on a magnetic disc 6 and converted into heat. When the resistor 4 comes into contact with a protrusion on the disc 6, a minute thermally changed region is generated in the vicinity of the contact point. When the thermally changed region spreads in the resistor 4, electric resistance of the resistor 4 is varied by the thermal coefficient. Consequently, when electrodes 3a, 3b are connected with lead wires, a current is fed to the resistor 4 through the lead wires, and the potential difference across the resistor 4, i.e., the potential difference between the electrodes 3a, 3b, is measured, variation in the electric resistance of the resistor 4 can be detected externally and a protrusion on the magnetic disc 6 can be detected.

Title: Curtain device for vehicle window glass
Inventor: YOSHIZAWA HIDEO
IPC: B60J3/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent removal of a forward or back guide rail from a side door window glass, or deformation of it by thermal stress. SOLUTION: Forward and back guide rails 14, 15 are separated to first rails 18, 18 and second rails 21, 21 respectively, and the second rails 21 is axially movable connected to the first rail 18.

Title: Method for repairing crack in metallic parts having surface crack
Inventor: TANAKA HIROYUKI
IPC: B22F3/24
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To easily repair crack exposed to the surface of metal and to prevent the generation of the problems of deformation and residual stress therein by sealing the part of crack on the surface of metal generated in a producing stage or a using stage by plating and then executing HIP treatment. SOLUTION: The crack generated on the surface of metallic parts is subjected to sealing treatment by plating. Since the sealing treatment can be executed without applying excessive heat to the metallic parts, the generation of distortion and residual stress is small. Furthermore, reinforcement of weld is small compared to the case by welding. After this sealing treatment, HIP treatment is executed. Thereupon, since pressure is not applied into the crack but applied from the surroundings, the part of the crack is crushed to produce pressure in the direction in which the crack is tightly adhered, by which diffusion joining occurs, and the repair of the part of the crack is executed. Moreover, in the case the plating treatment is executed by electroless plating, the plating metal can be allowed to enter the inside of the crack.  As the metal to be used for the plating, the one same as that of the metallic parts or different kinds of metal having good joinability with the metallic parts is used.

Title: Method and e uipment for measuring interference by observinginterference noise
Inventor: IEHIAMU PURAIA
IPC: G01B9/02
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To secure the measurement of interference without being influenced by the mechanical incompleteness and without the need for relative phase stability of high level by adding a phase turbulence unit to one of arms of divided beam, and thereby providing a random phase. SOLUTION: A phase turbulence unit 20 is arranged between a constant delay unit 12 of one of output beam 6 and a resynthesizer 8 to thereby provide a random phase. The additional random phase generates dissipation of high speed oscillations and converts them into an intensity fluctuation. Such fluctuation is analyzed statistically, leading to the statistical measurement of noise, which relates to the contrast of interference stripes in some arbitral optical path difference between two arms. The amplitude of fluctuation depends on the deepness of demodulation in some time delay, and envelope function of interference stripes is made obvious. Accordingly, the deepness of demodulation of interference can be measured with some statistic measurement of noise output from a COIN (coherence ovserving method) interference meter.
