Title: Torque sensor
Inventor: KAWASAKI KATSUYOSHI
IPC: G01L3/10
Filed: 1989-12-28
Abstract: PURPOSE:To obtain high detecting accuracy and to prevent the generation of pulsation by converting relative rotation between input and output shafts into the linear displacement of moving member and changing an opposed distance between opposed faces formed on the moving member and a magnetic path member in accordance with the linear displacement. CONSTITUTION:When torque occurs in the input shaft 2 by steering a steering wheel, the torque is transmitted to the output shaft 3 through a torsion bar 4. Since resistance corresponding to frictional force between the steering wheel and a road or the frictional force of the output shaft 3 is generated on the output shaft 3, relative motion delaying the output shaft 3 by twisting the bar 4 is generated between the input and output shafts 2, 3. Thereby, relative rotation corresponding to the input shaft 2 is generated also in a spool 7 whose rotational direction coincides with that of the output shaft 3, and since a ball 9 stored in an inner hole 7b of the spool 7 is stored in an outer peripheral spiral groove 2b of the input shaft 2, the spool 7 goes back and forth in the axial direction in accordance with the inclined angle of the groove 2b. Further, as the spring 8 energized the spool 7 in one direction, the play of the spool 7 in the gas is prevented.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To obtain large flexural performance and ductility by giving prestress to a concrete by a method wherein a high strength bar having a specific yield strength is used, and the high strength bar is strained by a load of a specific ratio of yield strength to yield strength. SOLUTION: Prestress is given to a concrete 4 by straining a plurality of high-strength bars 2 of 70-110kg/mm<2> yield strength by a load of 70% of yield strength to yield strength. From a standing point of a shrinked amount of the concrete, yield strength of a reinforcing bar to be used will do by at least 70kg/mm<2> . It is preferably at least 80kg/mm<2> near that of PC steel bar. Further, the reinforcing bar exceeding at most 110kg/mm<2> yield strength is comparatively high in manufacturing cost and must be avoided. Since the larger amount of prestress gives the higher rigidity of the pile, the larger amount of prestress is preferable.

Title: Damping mechanism, construction of vibration isolation making use thereof and damper
Inventor: ISHIMARU TATSUJI
IPC: E04H9/02
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To construct a damping mechanism in a narrow space without providing any special damper. SOLUTION: When a floor slab 12 is moved in the left direction, a double flooring 16 is relatively moved in the right direction, and a spherical body 14 starts to roll in the right direction between the floor slab 12 and double flooring 16. Then, since shear deformation of damping plates 11 and 13 compressively deformed by the spherical body 14 is made by plane frictional force between the damping plates and spherical body 14 and pushing pressure of the spherical body 14, damping force is displayed, and since frictional resistance between the damping plates 11 and 13 and spherical body 4 when it rolls is also simultaneously operated as damping force, the high damping effect is displayed by combination with them. While, even if the floor slab 12 is vibrated in the vertical direction, shear deformation of the damping plates 11 and 13 is made to damp vibration.
