Title: Ball screw device
Inventor: NAMIMATSU TAKESHI
IPC: F16H25/22
Filed: 1993-04-12
Abstract: PURPOSE:To support an axial load acting on a ball nut evenly for all the balls in ball screw grooves by selecting a clearance from the balls in the ball screw grooves with the amount of elastic deformation caused in the ball screw grooves taken into consideration. CONSTITUTION:The ball screw grooves 12 and 24 of a ball nut 20 are formed so that a clearance from balls 30 in load action line direction in the ball screw grooves 12 and 24 far apart from a mount part 25 for installing the ball nut 20 on a fixing member 50 becomes smaller than that in the ball screw grooves 12 and 24 nearer to the mount part 25 by an amount equivalent to the amount of elastic deformation caused in the ball screw grooves 12 and 24 by a load acting on the ball nut 20. Thus, when a large axial load is applied to the ball nut 20, the mount part 25 and the ball screw grooves 12 and 24 near the mount part are deformed, and the load can be supported by all the balls 30 in all the ball screw grooves 12 and 24.

Title: Standard piece for shock test
Inventor: NISHIDA KIMIYA
IPC: G01N3/31
Filed: 1982-05-18
Abstract: PURPOSE:To restrain variations in absorption energy and to reduce variations in test values by using metals which are made of pure metals or alloys stable in the point of structure, and which has a crystal structure of face-centered cubic lattice or dense hexagonal lattice. CONSTITUTION:Standard pieces made of pure titanium, pure copper and pure zinc were manufactured, and absorption energy of each of these standard pieces was measured by the Charpy test. More specifically, the test conducted in a temperature range of 20--193 deg.C resulted in that, in a range of 20--100 deg.C, the standard pieces showed just small difference in absorption energy and were stable, namely, that changes in absorption energy due to the temperature difference was small. Therefore, the use of these metals does not lead to changes in absorption energy due to the temperature difference during test, so that variations in test values can be reduced.

IPC: G05B13/02
Filed: 1986-04-11
Abstract: PURPOSE:To attain the automatic control of various controlled systems without performing the identification of the controlled systems by storing previously the human experience or perception as an inference rule and then inferring the control parameters from the feature value of the deviation between the test signal and the controlled variable based on said inference rule. CONSTITUTION:A feature value extractor 10 receives the deviation e(k) between a test signal T(k) and a controlled variable y(k) and outputs a feature value Si showing the characteristics of a controlled system 3. An inference rule storage unit 11 stores an inference rule Rj obtained from the human experience or perception in order to optimize the control parameters. A velocity type fuzzy inference unit 12 receives the value Si and then delivers the optimum parameters, i.e., the gain DELTAKC, the integration action time DELTATI and the derivative action time DELTATD based on the rule Rj. An integrator 13 receives these parameters and outputs them as the actual parameters after integration. A PID controller 4 receives the deviation e(k) between a target value signal r(k) and the value y(k) to decide a manipulated variable u(k) according to the control parameters, i.e., the gain KC, the integration action time TI and the derivative action time TD and delivers the value u(k) to the system 3.

Title: Method and device for evaluating material of surface acoustic wave substrate
Inventor: NAGATSUMA KAZUYUKI
IPC: H03H9/145
Filed: 1982-05-21
Abstract: PURPOSE:To improve the conversion coupling efficiency of the surface acoustic wave and to realize the evaluation of a material of a surface acoustic wave substrate with non-destruction, simplification and high accuracy, by using an electric signal/surface acoustic wave signal conversion coupler which utilizes the directional mode coupling effect of the surface acoustic wave. CONSTITUTION:Normal cross-finger electrodes 1 and 2 are formed on a 128 deg. XY plate of a single crystal of lithium niobate LiNbO3 having 2mm. thickness and 50mm. diameter with mirror surface polishing applied. A groove 3 is formed at the center part between both electrodes 1 and 2 and in the direction approximately vertical (88 deg.) to the propagating direction of the surface wave. The LiNbO3 single crystal plate 4 is held on a metallic holding container, and a 128 deg. YX plate 10 of LiNbO3 to be evaluated is put on said holding container. The plate 10 is adsorbed by a vacuum pump. Two sheets of LiNbO3 single crystal plates have a contact with each other at an electrode draw-out part 7 via an Al film. The effective component of the surface acoustic wave oscillated by the input electrode 1 on the lower LiNbO3 single crystal plate is transmitted toward the output electrode 2. A part of the transmitting energy is transferred onto the upper LiNbO3 single crystal which is opposed in parallel to the lower crystal plate after the surface acoustic wave travels a proper distance. The rest of the energy is irregularly reflected by the groove 3 and prevented from entering directly the electrode 2.

IPC: B21B1/22
Filed: 1982-05-21
Abstract: PURPOSE:To prevent the generation of roll mark caused by seizure, and to reduce a rolling load and power consumption, by cold rolling a strip under the existence of a water soluble lubricant and water after previously forming the film of a phosphate or a oxalate on the surface of the strip, in multi-pass rolling by a single stand. CONSTITUTION:In multi-pass rolling by a single stand, the film of a phosphate or a oxalate whose amount to be used is 0.1-10g/m<2> is previously formed on the surface of a strip, and then, the strip is cold rolled under the existence of a rolling oil, a water soluble lubricant, and water. The coated film mentioned above remains uniformly on the surface of the strip even after the strip is rolled, and the film is effective for preventing the generation of roll mark caused by seizure during rolling and for reducing the rolling load and the power consumption. Accordingly, by this method, the number of times of rolling passes is remarkably reduced, and the number of stands of a tandem mill is also reduced, and moreover the mechanical properties of a final product is improved.

Title: Exciting method for closed-loop superconducting coil
Inventor: MUKOYAMA SHINICHI
IPC: H01F6/00
Filed: 1993-03-22
Abstract: PURPOSE:To make a permanent current flow by a simple operation by a method wherein a permanent current flows by adding pulse-like magnetic flux to a closed loop superconducting coil formed with a superconductor having hysteresis against pulse-like magnetic flux changes. CONSTITUTION:A secondary coil 2 is a closed loop formed with a superconductor and arranged at a position where interlinkage of magnetic flux generated from a primary coil 1 takes place. The primary coil 1 is connected with a pulse power source 3 which can turn on/off a current for a short time from an external unit and a pulse current flows through the primary coil 1. Thus, the primary coil 1 generates the pulse-like magnetic flux which reaches the secondary coil 2. In a superconducting wire in which a fine superconducting filament is embedded in a normal conduction metal such as copper, etc., the secondary coil 2 has hysteresis against the pulse-like flux, and if the magnetic flux on the primary coil side is zero, a permanent current is left in the secondary coil 2. Thus, a great permanent current can flow easily and promptly in a closed loop superconducting coil.
