Patent JP-H02109785-A (JP)
Title: Tractor
Inventor: KAMATA MASAYUKI
IPC: B62D21/14
Filed: 1988-10-17
Abstract: PURPOSE:To easily adjust a distance between right and left front and rear wheels by crossing a frame, supporting the left side front wheel and the right side rear wheel, with a frame, supporting the right side front wheel and the left side rear wheel, further adjusting the frames to be turned each other in a horizontal direction. CONSTITUTION:A hydraulic cylinder 18 is controlled to an extension or contraction side, and a distance between right and left front wheels 1, 1 and between right and left rear wheels 2, 2 is adjusted to a spread or reducing side through rice field frames 3a, 3b and steering cases 16, 16, 17, 17. Here because the right and left front and rear wheels 1, 1, 2, 2 form a parallel link by interlocking rods 19, 19, 20, 20 and both the frames 3a, 3b, the wheels are maintained in a straight advancing attitude with no turning motion. While by controlling a steering arm 5 to be turned in one side or the other, the right and left front and rear wheels 1, 1, 2, 2 are simultaneously turned and steered to one side or the other through a steering interlocking mechanism 6. Accordingly, in case of adjusting the distance between the wheels, the necessity for adjusting a steering interlocking system is eliminated.

Title: Method for preventing inclination of seal ring in master cylinder
Inventor: KAWABE YUTAKA
IPC: B60T11/20
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To prevent an inclination of an outer seal ring, and effectively prevent an increase of sliding resistance at the operational primary stage caused by the inclination, and defective return of the piston. SOLUTION: The inclination of an outer seal ring 55 occurs by the force accompanied with elastic deformation of an inner seal ring 53. Then, such force of the inner seal ring 53 is weakened as much as possible. For that purpose, hardness of the inner seal ring 53 made of an elastic material is lessened. However, if the hardness is too lessened, the force which radially outward pushes the outer seal ring 55, i.e., the sealing force of the outer seal ring 55 is inadequate. Thus, the hardness of the inner seal ring 53 is preferably set for Hs 55-65 in Shore hardness, in order to effectively prevent the inclination with the sealing force of the outer seal ring 55 maintained properly.

Abstract: PROBLEM TO BE SOLVED: To reduce a loss caused by a positive voltage of a rectifying circuit and reduce a leakage loss due to a reverse leak by disposing a pressure reducing circuit in which power after an AV power is rectified by the rectifying circuit is pressure-reduced and transferred to an output end. SOLUTION: In this wrist watch device 10, a vibration piece 21 is vibrated by movement of a user arm or the like and power is generated. An AC power from this power generator 1 is rectified by a rectifying circuit 2 constituting a bridge by a diode 3. Power charged with an input auxiliary capacitor 34 of this rectifying circuit 2 is transmitted to output ends 32 and 33 via a pressure reducing circuit 40. At the output end 32, a large capacitance capacitor 5 is connected, and the capacitor 5 is charged by output of the pressure reducing circuit 40. By disposing such pressure reducing circuit 40, a voltage of an input end can be enhanced, therefore, a voltage after rectifying the rectifying circuit 2 can be set highly. Consequently, even if the positive voltage is the same, the rectification efficiency can be enhanced, thus making it possible to reduce a loss.

Filed: 1993-09-28
Abstract: PURPOSE:To automatically and easily make the Si concn. of a continuously produced high-Si concn. steel strip coincide with a target Si concn. with high accuracy regardless of a fluctuation in the thickness of the steel strip. CONSTITUTION:The thickness of the steel strip 1 on the inlet side of a siliconizing furnace 2 is measured online by a thickness gage 7.

Title: Impact dot head
Inventor: FURUTA KATSUMI
IPC: B41J2/28
Filed: 1987-10-20
Abstract: PURPOSE:To continuously conduct a high-speed or high-density printing, by a method wherein a non-magnetic metal member with a high thermal conductivity subjected to a surface insulating treatment is disposed between an electromagnetic coil and a holding member. CONSTITUTION:During waiting, a plunger 3 is attracted to a core 5 by a permanent magnet 4; during printing, the attraction of the plunger 3 to the core 5 is released due to an electric conduction to an electromagnetic coil 2, whereby a printing wire 8 bonded to a tip end of a lever 7 is projected by the force of a plate spring 6. The repeat of this printing action generates a large quantity of heat in the coil 2. However, the electromagnetic coil 2 is prevented from overheating because the heat is radiated through aluminum members 1, 11, which are disposed in gaps between the coil 2, an outer circumferential metal part 9, and an inner circumferential metal part 10 with surfaces subjected to an insulating alumite treatment. Additionally, aluminum never affects a magnetic circuit because of its non-magnetic properties. The aluminum members 1, 11 which are subjected to a surface alumite treatment and fitted in shape for the gaps between the electromagnetic coil 2, the outer circumferential metal part 9, and the inner circumferential metal part 10 are disposed dividedly into five segments and integrally as one segment.
