Title: Magneto-resistance type magnetic head
Inventor: HIRANO AKIRA
IPC: G11B5/48
Filed: 1986-12-04
Abstract: PURPOSE:To detect even a minute shift against a track of a magnetic storage medium, and to improve the detection accuracy by making the width of a magneto-resistance element which consists of a magnetic anisotropic material, and whose axis-of-easy magnetization direction is used as lengthwise direction, different in the center part and the side part. CONSTITUTION:As for a slender magneto-resistance element 12 which consists of a magnetic anisotropic material such as 'Permalloy(R)', etc., and whose axis-of-easy magnetization, the center part in the lengthwise direction is a narrow width magnetism detecting part 12a, and both outsides are wide width magnetism detecting parts 12b, 12c. In the magneto-resistance element 12, an equipotential thin wire 13 consisting of a good conductive material is formed at an angle of 30-60 deg. with its axis-of-easy magnetization. When a prescribed current is allowed to flow to a magnetism detecting element 11 constituted in such a way, and an external magnetic field is brought close, an output characteristic of the element 11 is related to width w1 of the center narrow width part, its length l and wide width w2. When the length l of the center part 12a is made almost equal to width of a track of a magnetic storage medium, a shift of the external magnetic field can be detected clearly from its output.

Title: Reverse gear noise preventive mechanism for manual transmission of car
Inventor: ONO HIROKI
IPC: F16H63/30
Filed: 1989-11-10
Abstract: PURPOSE:To prevent generation of reverse gear noise at a low cost by furnishing a multi-plate clutch to detain an input shaft with a stationary member of a transmission case through the pressing surface of a neither ring of a synchronizing device. CONSTITUTION:When a reverse shift position is selected, a coupling sleeve 18 is slided left, and a shifting key 19 is slided in the same direction through detention of a protrusion on this key 19 with a detent groove provided in the coupling sleeve 18. At its end face a neither ring 24 of a synchronizing device 17 is pushed and moved. At the pressing surface 24c a multi-plate clutch 32 is engaged frictionally to cause the neither ring 24 to stop rotating, and an input shaft 1 in rotational coupling will stop immediately because clutch is already disengaged. Thereafter a reverse gear train is put in meshing, and operation is made in the reverse gearing position, but because the input shaft 1 is at a standstill at the time of meshing, no gear noise will be generated. Further, this can be accomplished at a low cost because no precision processing is required.
