Title: Torque sensor
Inventor: HASE HIROYUKI
IPC: G01L3/10
Filed: 1988-12-27
Abstract: PURPOSE:To decrease change with time in sensor output by applying corrosion prevention treatment on the shaft of a torque sensor on the surface of which a soft magnetic alloy layer having magnetostriction is formed or on a part of said soft magnetic alloy layer. CONSTITUTION:Nickel plating 1a and the like are applied on a steel shaft 1 so as to improve corrosion resistance. Amorphous alloy 2 comprising the composition of Fe-Cr-Si-B is manufactured by super-quick cooling piece rolling method. Thereafter, heat treatment is performed at Curie temperature or more and crystallizing temperature or less. The alloy is bonded to the shaft 1. The amorphous alloy 2 indicates the same corrosion resistance as that of stainless steel SUS303. A bobbin made of Teflon is arranged coaxially with the shaft 1. A coil 4 is wound around the bobbin. Since the occurrence of corrosion is suppressed on the torque sensor in this constitution, the stable output is obtained for heat cycles.

Title: Rotary polyhedral mirror
Inventor: KAINO NORIYUKI
IPC: G02B26/12
Filed: 1992-12-15
Abstract: PURPOSE:To obtain the rotary polyhedral mirror formed with reflection mirrors on the flanks of a polygonal column which is produced by a working method which does not require the intricate curved surface working of the molds to be used for molding and is small in the deformation quantity to be generated during use under rotation by forming projections over the entire periphery of the outer peripheral edges of the upper surface and back surface of the polygonal column or a part of the outer peripheral edges thereof. CONSTITUTION:The uniform projections 7 are provided over the entire periphery of the peripheral edges of the upper surface 2 and back surface 3 of the polygonal column of the rotary polyhedral mirror in order to approximately uniformly increase the deformation quantity at the entire peripheral edge of the flanks 1. Centrifugal force is generated at the projections 7 when the rotary polyhedral mirror is rotated if the projections is provided in such a manner. This centrifugal force acts as the additional centrifugal force on the peripheral edges of the upper surface 2 and back surface 3 of the rotary polyhedral mirror. Consequently, the deformation quantity on the flanks 1 of the part in contact with the entire peripheral edge of the upper surface 2 and the back surface 3 increase. The difference between the deformation quantity on the flanks 1 in the parts in contact with the entire peripheral edge of the upper surface 2 and the back surface 3 and the deformation quantity in the central part in the height direction of the flanks 1 decreases. The distortion quantity of the flanks 1 and the ridges 5 diminishes.
