Title: Magnetostriction type torque sensor
Inventor: MORIKAWA KUNIHIKO
IPC: G01L3/10
Filed: 1987-06-25
Abstract: PURPOSE:To improve detection accuracy and to reduce the size of apparatus by providing coils for torque detection to the opposite yokes of a rotating body and detecting the direction and size of torque from a change in the magnetic permeability occurring in the torsion by the torque. CONSTITUTION:Magnetic fluxes phi are generated when excitation current is passed to the coils 22A, 22B provided to the yoke parts facing the collar part of a gear. The magnetic fluxes phi are passed only through the surface part by a skin effect and have 45 deg. angle of inclination with the radial direction of the rotating body. Torque detecting surfaces 24A, 24B on both sides have shape magnetic anisotropy. The detecting surfaces 24A, 24B on both sides have the same magnetic permeability and the electromotive forces of the coils are equaled when the torque is not applied to the gear at this time. Tensile and compressive torsions are generated and the magnetic permeability of the surfaces 24A, 24B change when the torque is applied on the gear. This change is taken out as an electric signal and the direction and value of the torque are detected. The detection accuracy is thereby improved and the size of the apparatus is reduced.

Title: Contact type image sensor
Inventor: NATSUKAWA SHINJI
IPC: H04N1/04
Filed: 1985-07-16
Abstract: PURPOSE:To read the white surface of a drive roller when the width of an original is narrower than the reading width and to read regions at the outside of the original as a white level by using an LED illumination light source and fitting the light source to the opposite side to the roller shaft position with a sensor read shaft. CONSTITUTION:The original 1 runs toward the arrow by an original drive roller 6. In lighting the original face by the LED illumination light source 2, the reflected light component is led to a photodetector 3 through a near convergent fiber light guide system 4 to display the original picture onto the photodetector 3. When the original width is narrower than the reading width, the light from the light source 2 at the part at the outside of the original lights the drive roller 6. Since the path of the major component of the light is close to the path of the original face, the reflected light component of the white part of the surface of the roller 6 enters sufficiently the convergent fiber light guide system 4 so as to attain the region at the outside of the original as a white color.
