Title: Measuring method for motion accuracy
Inventor: SHIMAZUTSU HIROAKI
IPC: G01B21/22
Filed: 1986-05-20
Abstract: PURPOSE:To perform motion accuracy measuring operation with sufficient accuracy and manoeuverability by installing three displacement detectors at equal intervals and processing their measured values. CONSTITUTION:The three displacement detectors A-C which measure the distance between a fitting table 10 and an object 8 of displacement measurement are installed at intervals L. Their measured values at a measurement start position are denoted as D'0.A, D'0.B, and D'0.C and the table 10 is moved by the intervals L to obtain the measured value at each other. Then, the quantity of deviation of the position where the indicated value of a detector B is zero from the line connecting the positions where the indicated values of detectors A and C are zero is grasped and a constant C' determined by the fitting condition of the detectors, etc., is found as the value twice as large as said quantity, thereby obtaining variation DELTAthetaK+1 in the quantity of pitching inclination at the time of movement from the (K)th measurement position to the (K+1)th measurement position by using an equation I. Then, the quantity theta0 of the pitching inclination at the measurement start position is set to zero and the quantity thetaK+1 of inclination at each measurement position is found from an equation II. Further, the quantity DELTAeK+1 of deviation is obtained similarly from an equation III and the quantity e0 of deviation from a movement guide axis at the measurement start position is set to zero, thereby obtaining the quantity eK+1 of deviation from the axis at the measurement position from an equation IV.

Title: Superconducting motor
Inventor: KANBE YOSHITAKA
IPC: H02K55/06
Filed: 1995-05-15
Abstract: PURPOSE: To obtain a superconducting motor in which the number of turns of an armature winding is increased and by which a desired torque is obtained by a method wherein the amount of the component of a current flowing in the central direction of a rotor in a part not covered with a superconducting shield is made different from that of the component of a current flowing toward the radial direction. CONSTITUTION: When a constant DC current is made to flow to a solenoid coil 3, a magnetic field turning up from below is generated in the interior of a pore. In a disk-shaped rotor 5, a line of magnetic force is going to pass through the surface side from the rear side. However, since a superconducting shield 6 has been installed, the line of magnetic force cannot pass through the keeps away from the rotor so as to pass through. On the other hand, in an armature coil 8, positions of collector brushes 11, 12 and those of commutators 13, 14 are set in such a way that the direction of a current in a position in which a part in the radial direction turns horizontal is reversed. As a result, the current which always turns up flows in the part in the radial direction.  Consequently, the current in the radial direction in a part not covered with the superconducting shield 6 always flows toward the circumference from the center, Lorentz's force acts, and a turning force in the right rotation is given. As a result, it is possible to obtain a motor which is small and whose output is high.

Title: Electronic musical instrument
Inventor: AOKI EIICHIRO
IPC: G10H1/34
Filed: 1990-05-01
Abstract: PURPOSE:To vary a pressure signal steeply by utilizing a signal in which data supplied from a performance operator is differentiated also as pressure data in an electronic musical instrument setting pressure as one of elements to form a musical sound signal. CONSTITUTION:The signal in which the data supplied from the performance operator 1 is differentiated is utilized as the pressure data. In other words, when a player performs a performance operation equivalent to the operation of the string of a string instrument by operating the knob 2 of the performance operator 1, a position in accordance with the movement of the string is generated from the performance operator 1. A string speed signal is formed by differentiating the position signal at a differentiation circuit 5a. An acceleration signal to form positive and negative peaks at the leading and trailing edges of the signal can be obtained by differentiating the string speed signal. A tone is weak at the leading edge of the pressure data, which makes an attack part (head) hard to be formed. Therefore, the acceleration signal is added on the pressure data. Thereby, the pressure signal changing steeply can be obtained.
