Title: Motor controller
Inventor: GOTO YUICHI
IPC: H02P6/10
Filed: 1992-05-25
Abstract: PURPOSE:To provide a motor controller which can stably control a rotating speed. CONSTITUTION:A controller 1 for a motor M compares a frequency signal proportional to a rotating speed of the motor M with that to become a reference, and controls an exciting current of the motor by an exciting current control circuit 5 based on a compared result. The controller 1 comprises an exciting current detector 6 for detecting an exciting current of the motor M, and a high frequency feedback circuit for feeding back only a high frequency component of the current detected by the detector 6 to the circuit 5 to phase- compensate it to attenuate a gain of the high frequency component of the current. With this configuration, a stable speed control is performed irrespective of the speed and a load.

Inventor: MIZUKI TAKAYUKI
IPC: G06F3/0487
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To output the three-dimensional data to a controlled equipment via the operation of a tablet by detecting the X and Y coordinates of the contact position of resistance plates and the contact resistance value as the independent three-dimensional parameters when the resistance plates are pressed. SOLUTION: The potential of an X- side electrode 8b and a Y+ side electrode 9a are read, and the 1st potential difference is detected between the X and Y coordinate plates 8 and 9 at their contact position. Then the potential of a Y- side electrode 9b and an X+ side electrode 8a are read, and the 2nd potential difference is detected between both plates 8 and 9 at their contact position. In a contact resistance detection mode where the contact resistance value rp is calculated at the contact position from a function that shows the value rp in the 1st and 2nd potential differences, the X and Y coordinates of the contact position and the value rp are detected as the independent three- dimensional parameters. Thus, the threedimensional data can be outputted to a controlled equipment via the operation of a tablet.

Title: Copying device
Inventor: NAKAYAMA MIHO
IPC: G03G15/00
Filed: 1990-05-24
Abstract: PURPOSE:To correct a set mode after releasing jamming by providing a registering means for registering a 2nd copying mode in the case that the jamming occurs while the 2nd copying mode is set after a 1st copying mode is set. CONSTITUTION:A reservation key 602 is depressed to obtain such a state that a copying mode different from the copying mode already set can be set. By depressing a reservation setting key 603 after setting a copying mode which should be registered, at such a time, the set copying mode is stored in the RAM 803 of a controller 800. In the case that the jamming occurs while the 2nd copying mode different from the 1st copying mode is set, the 2nd copying mode which is set by the time when the jamming occurs is stored in a buffer and a flag to store that the copying mode different from the 1st copying mode is in the middle of being set is raised in order to set a jamming release waiting state. Thus, the set mode is corrected after the jamming is released without making the mode set before the jamming occurs ineffective.

Title: Magnetic scale signal detector
Inventor: NARIMATSU AKIYOSHI
IPC: G01D5/245
Filed: 1978-10-27
Abstract: PURPOSE: To obtain digital scale for the simple detection circuit by securing the parallel arrangement for the detection elements of the ferromagnetic substance featuring the anisotropic effects of magnetic resistance in correspondence to the natural wavelength of the magnetic grid.  
     CONSTITUTION: The elements are arranged with space secured between the elements, and bias magnetic field HB is given in the direction of about 45° to elements 7 and 7'. At the same time, two units of component elements 11/11' and 12/12' are connected to output terminals b and b' in such distribution as to feature the phase difference of 180° (=λ/2), thus redoubling the detection signal output. In such element constitution, the frequency output identical to the wavelength frequency of the magnetic scale is obtained. In this connection, when the double-phase output of phase difference 90° is wanted, two detection elements 8 and 8' are distributed with the space of (m/2+1/4)λ, where m means an integer. And if each element resistance of the detection elements are made equal virtually to each other at the position where the signal magnetic field of the magnetic scale is zero, the zero-cross detection position can be decided in a stable way.

Title: Pulley for cogged belt of internal-combustion engine
Inventor: NAKAMURA MAKOTO
IPC: F16H55/36
Filed: 1983-07-22
Abstract: PURPOSE:To make a cogged belt pulley in lightweight structure and prevent vibration and noise generation owing to cross swing of the belt by furnishing a resilient member at the inside surface of the rim of pulley provided with cogs on its periphery. CONSTITUTION:Pulley 7 is composed of a boss 4 and a rim 1, the latter being equipped with involute teeth 3 on its periphery at a constant spacing, wherein the boss and rim are coupled together by an arm part 5. In this case, the inside surface 11 of this rim 1 is lined with a resilient member 10 made of rubber. Thereby, if meshing of the belt 8 with pulley 7 gives it an impact, the rim 1 or arm part 5 is going to deform in minor scale to lead to small deformation even in the resilient member 10 alike, but a great internal damping characteristic of this resilient member 10 will suppress said tendency of deformation. Accordingly vibration to be caused by impact at the time of meshing can be reduced.
