Title: Manufacture of magnetoresistive element
Inventor: BABA KENICHI
IPC: G11B5/39
Filed: 1994-06-29
Abstract: PURPOSE:To suppress Barkhausen noises and to make it possible to suppress the decrease in reproduced output to a slight degree by making inert gas flow when a magetoresistive element is formed by vacuum evaporation. CONSTITUTION:For example, when a magnetoresistive element magnetic head, i.e., a magnetoresistive element used for an MR head that is an NR element, is formed by vacuum evaporation, the crystal grain diameter of the evaporated film can be made small by introducing inert gas such as argon gas and nitrogen gas. Thus the occurring rate of Barkhausen noises can be suppressed. Meanwhile, stable operation is achieved even if the reproduced output is slightly lowered. Therefore, when the MR element manufactured by this method is applied on the MR head and the head, wherein the MR head and an induction head are combined, the stable operation is secured, and the Barkhausen noises can be suppressed.

Abstract: PURPOSE:To simplify the configuration by furnishing a vibro-suppressing rotary weight which rotates at a certain angle speed interlocked with a crank shaft, and setting the axis of rotation in the direction perpendicular to the longitudinal cross-section of the internal combustion engine concerned. CONSTITUTION:When a crank shaft 1 rotates, a front 2a and a rear 2b counter weight generate moments in the directions up and down and to the left and right, that will damp the unbalanced primary moments of engine in the directions up and down and to the left and right. Primary balancers 3a, 3b rotate in the opposite direction while synchronizing with rotation of the crank shaft 1, and the moment generated by these balancers 3a, 3b damps said unbalanced primary moment certainly. A single rotary weight 10 is rotated at a certain angle speed by means of adjustment of an angle adjusting device 11, and accordingly a centrifugal force is generated. proper setting of the mass and phase of this rotary weight 10 should well damp the unbalanced secondary moment.

Title: Method and apparatus for measuring position of moving body
Inventor: KATAYAMA YUKINORI
IPC: G01B11/00
Filed: 1986-06-25
Abstract: PURPOSE:To measure the position of a moving body accurately and rapidly, by operating the correlation between a sample image and an input image with respect to a plurality of spatial frequency components different from each other at every separate corresponding component. CONSTITUTION:The sample image of an objective moving body and the input image at every small region within a predetermined visual field containing the moving body are separated into three high, low and medium spatial frequency components by first-third filters 41-43 to be stored in first, second and third sample image memories 61-63 and first, second and third input image memories 51-53 at every corresponding spatial frequency component and image correlations between them are operated by first, second and third correlation operators 81-83. Next, separate weighting capable of most enhancing the degree of separation of the moving body and a background experientially at every small region is applied to three kinds of correlation values to synthesize said values at each time. Therefore, even when there is a background well resembling the moving body in the background, if the moving body and the background can be discriminated on the basis of only one component among three spatial frequency components separated, the moving body and the background can be separated and discriminated by performing weighting emphasizing the correlation value corresponding to each component.

Title: Forming of copper hollow structural body
Inventor: FUKUSHIMA AKIRA
IPC: B23K1/19
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a structural body which is easily applied to a copper hollow structural body of a complicated shape and enables mass production and cost reduction by applying Au plating to a joint part of a groove and a cover formed with copper, and heating/joining them in a furnace. SOLUTION: A gold plated layer 6 of 20-40 μ thick is formed on the side of a pure copper cover 2 joined with a pure copper groove structural body 1, and is put on the body 1 and held in a vacuum furnace at 1,010 deg.C for 30 minutes. Thus, the gold (melting point is 1,063 deg.C) of the gold plated layer 6 and the copper (melting point is 1,083 deg.C) are alloyed by diffusion, resulting in the reduction of the melting point. They function as a Au-Cu brazing material, so that the body 1 and the cover 2 are thermal-joined by brazing in the furnace to form the copper hollow structural body. Therefore, since gold plating can be easily carried out even in the case of a difficult-to-apply complicated shape, the copper hollow structural body can be easily formed according to this method. Furthermore, mass production is possible, resulting in reduction of cost for manufacturing the copper hollow structural body.
