Title: Magnetic recording medium
Inventor: YANAI AKIO
IPC: G11B5/64
Filed: 1987-10-23
Abstract: PURPOSE:To provide excellent electromagnetic conversion characteristics to the title medium by forming weave patterns on the surface of a high-polymer primer coating layer and specifying the average surface area of the unit cells of the weave patterns to a specific value and the surface roughness of the under coating layer to a specific value. CONSTITUTION:The high-polymer primer coating layer 2 formed on a nonmagnetic base 1 is formed continuously with the regular patterns having the weave pattern-like surface structure provided with the approximately hexagonal ruggedness occurring in the generation of convection cells over the entire surface of the coated film. This weave-patterned surface is preferably formed as 0.1-0.1mum difference (d) in unduration between projections A and valleys B and 3X10<-6>-3X10<-3>mm<2> average area in the average size of the unit cells. The spacing between the medium and head is widened and the satisfactory recording and reproduction are not possible if the surface roughness exceeds 0.1mum. The traveling is unstable if the unit area of the unit cells exceeds 3X10<-3>mm<2>. Conversely, the surface roughness decreases to <=0.01mum and the stable traveling is hindered if the area of the unit cells is below 3X10<-6>mm<2>.

Abstract: PURPOSE: To accomplish meshing without any backlash in a toothed shaft profile by cutting a nipper type slit in an intermediate bush end and spreading it radially when it is pressed to a return stopper. CONSTITUTION: An expansion leg 29 is inserted into a gap between teeth in an outside face toothed shaft profile 34 in a rotary shaft terminal end 12' until it is brought tight contact with adjacent tooth side faces without any backlash.

Title: Coordinate calibrating system
Inventor: YAMAMOTO TAKAHIRO
IPC: G01B11/24
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To permit the highly accurate compatibility of abscissas by irradiating a test surface with a beam of light for measurement emitted from a light source, bringing the reflected beam of light for measurement into interference with a beam of light for reference with a predetermined wavefront, and detecting the state of generated interference fringes. SOLUTION: The surface accuracy of a spherical surface is measured by an interference measuring machine 1 with spherical waves which are generated by a Fizeau lens and a condensing lens and have horizontal distortion unknown to a CCD. In addition, the same test surface is measured by a coordinate measuring machine 2 capable of accurately ensuring abscissas. As coordinate distortion at the time of interference measurement is approximately rotation-symmetric, it is satisfactory to perform similar coordinate calibration on coordinates in concentric circles. In addition, as sampling in concentric circles can be performed in the case that rotation-symmetric waviness is verified in the test surface accuracy in positioning is improved. For calibrating all coordinates, it is necessary to specify positioning points different in distance from the center.  By obtaining the relationship of the amount of coordinate correction by distances from the center as a function of coordinate transformation, it is possible to perform overall surface coordinate calibration even from discrete positioning points.

Abstract: PURPOSE: To measure the number of rotation of a working shaft and an output to be transferred by providing different number of pulse generation bodies at two arc parts of each measurement plate and evaluating the output of a sensor device with an electronic comparison device. CONSTITUTION: Two measurement plates 2 and 3 are fixed at a working shaft 1 with a space in axial direction and a number of pulse generation bodies 10 (black line in radius direction) are provided at the positions of inner arc parts 8 and 9 and outer arc parts 18 and 19 of the transparent measurement plates 2 and 3. Then, the number of the generation bodies 10 is made larger at the arc part 18 than at the arc part 19 and is made smaller at the arc part 8 than at the arc part 9. By overlapping the measurement plates 2 and 3, regions 20 and 21 with the minimum light transmission property and regions 22 and 23 with the maximum light transmission property can be obtained. Therefore, when sensors 6 and 16 allow light to pass through the generation bodies 10 in axial direction and then receive it 7 and 17, an analog output 12 and a digital output 15 are obtained from an electronic comparison device 11. Then, when the work shaft 1 is twisted due to torque and the relative positions of the measurement plates 2 and 3 deviate, nontransmission regions 20 and 21 move in opposite directions. Therefore, by measuring the distance, a torque can be expressed.
