Title: Nonlinear optical material and its production
Inventor: KINERI TOORU
IPC: G02F1/35
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To increase the performance coefft., specially the performance coefft. in a nonresonance region by individually dispersing metallic fine particles in a light-transmitting substrate and preparing the substrate as a single crystal. SOLUTION: This nonlinear optical material consists of a light-transmitting substrate and fine particles of at least one kind of metal individually dispersed in the substrate. The substrate is made of a single crystal. Since the metallic fine particles are confined three-dimensionally in the light-transmitting substrate, nonlinearity is obtd. by, for example, excitation of the surface plasmon of the metallic fine particles and the quantum size effect. As a result, a nonlinear optical material having optical bistability and an optical relaxation time in pico seconds order is realized and it can be used for an optical switch or an optical wavelength convertor such as THG. Thereby, the obtd. nonlinear optical material has large performance coefft. x<(3)> /α (α is the absorption coefft.) and especially, large x<(3)> /α in a nonresonance region.

Title: Tooth groove runout correcting method of master gear for automatic gear selector
Inventor: MIZUNO MAKOTO
IPC: B23F23/00
Filed: 1993-10-25
Abstract: PURPOSE:To provide a method which can be used as correction data by measuring easily runout of a master gear in a two-teeth surface meshing tester by using the master gear. CONSTITUTION:A displacement detector 14 is arranged in a two-teeth surface meshing tester 10, and a signal of this detector 14 is automatically processed by a measuring device 20 through an amplifier 15 and an A/D converter 16. The two-teeth surface meshing tester 10 meshes a master gear MG and a work gear WG with each other, and rotates the master gear MG and the work gear WG continuously, and measures runout between both gears by a quantity corresponding to the number of teeth of the master gear MG. After a meshing phase between the master gear MG and the work gear WG is shifted by a proper distance by counting rotating speed of the master gear MG, the runout between both gears is measured again by a quantity corresponding to the number of teeth of the master gear MG. This is repeated by the number of teeth of the work gear WG, and the runout between both gears is converted into an average value, and runout of the master gear MG is found, and this is used as correction data to measure runout of the work gear WG.

Title: Determination of shape of strip-like coil on cylindrical surface
Inventor: YODA KIYOSHI
IPC: H01F41/00
Filed: 1989-10-13
Abstract: PURPOSE:To obtain the inductance of a coil at a high speed by performing a current Fourier conversion, multiplying the square of the absolute value of the result by a deformation Bessel function, and integrating it in a k space. CONSTITUTION:Current distribution calculating means 1 obtains a current distribution in the circumferential direction of a strip-like coil disposed on the outer periphery of a cylinder. Inductance calculating means 2 performs Fourier conversion at the distribution, multiplies the square of the absolute value of the result by a deformation Bessel function, and integrates it in a k space, thereby obtaining a self-inductance of the coil. Allowance determining means 3 determines whether the size of the inductance falls within a preset allowable range or not, coil shape altering means 4 alters the shape of the coil when it is determined that the inductance is not fallen within the allowable range. Thus, inductance calculating time can be shortened.

Title: V-belt continuously variable transmission
Inventor: OTSUBO HIROSHI
IPC: F16H63/18
Filed: 1993-10-27
Abstract: PURPOSE:To prevent the pressedly contacting force between a transmission belt and pulleys from becoming weak due to the wear of the transmission belt, and to prevent the pulleys from becoming liable to slip by providing a mechanism by which a fixed cam body is turned and energized so as to narrow the distance between both pulley-blocks. CONSTITUTION:When a transmission belt 5 wears and becomes narrow by use of a long period of time, since the position of a fixed cam body 9 in a rinding-on cam mechanism 8 on the other side is fixed, the distance between pulley-blocks 3, 4 is maintained in a prescribed condition; while in the riding-on cam mechanism 8 on the other side, since the proper belt winding diameter slightly changes to a smaller diameter side, the belt is slackened. In such a case, the pulley-blocks are energized by an energizing mechanism 15 in such a direction that the distance between the pulley-blocks 3, 4 is narrowed, so that the transmission belt 5 is set in a proper winding condition for transmission. Thus, the slip of the pulley blocks 3, 4 due to the wear of the transmission belt 5 can be previously prevented, and a smooth transmission condition can be maintained for a long period of time. Further, the structure of the transmission can be simplified.

The TaMo layer 7 is formed of TaMo alloy which contains 20-30at% of Ta basing on the resistance change of the alloy when it is made to stand exposed to a high temperature and the corrosion resistant property proved through a pressure cooker test. In result, even if there is variation of 5% or so the thickness of a conductor pattern forming film and a TaMo film and a milling rate in which the unnecessary part of the conductor pattern forming film is removed, a magnetic substance pattern can be formed without being affected by the variation, so that a magnetoresistance element can be decreased in hysteresis.
