Abstract: A motor driving apparatus capable of predicting motor insulation deterioration at low costs. When a motor drive amplifier is not in operation, a relay contact K1 is turned on or closed to form a closed circuit of a motor housing grounded at G2, a motor coil, resistors R1, R2, the relay contact K1, diodes D4, D5, D6, an AC power source, and a ground point G1. A voltage of the AC power source to ground is applied to the closed circuit. When the insulation resistance of the motor is high, a small current flows through the closed circuit, so that potential difference across the resistor R1 is small. If the motor insulation is deteriorated, a leakage current increases. If potential difference across the resistor R1 exceeds a reference voltage determined by a Zener diode, an output signal is output from a comparator, a signal is output from a photocoupler, and the decrease in insulation resistance is indicated on an indicator of a control unit.

Abstract: The invention presents a magnetic recording and reproducing apparatus capable of reducing the size and preventing external force from propagating directly to the internal mechanism. To achieve the object, a main arm 26 and a sub-arm 29 are constituted so as not to intersect with a photo detector 31 always during rotating operation within a plane including the photo detector 31, and the dimension can be hence reduced in the width direction of the apparatus, and moreover as the wall thickness of MIC-SW 46 is reduced, the upper end of the MIC-SW 46 is held by a back plate 48, so that the dimension of the apparatus can be reduced also in the depth direction, and further a cassette holder 13 is locked by a damper 42 to prevent effects from outside when a sub-chassis 19 moves from unloading position to loading position.

Abstract: It is assumed that an element to be detected 2a in a position sensor is mounted on a rotary shaft with the center O′ of the element to be detected eccentric from a center of rotation O by a distance d. When the rotary shaft is rotated at a fixed speed, the positions at angles 0° and 180° are accurately detected by a sensor 2b, while the positions at angles 90° and 270°, the sensor detects the positions P1′ and P3′, instead of P1 and P3 which are originally to be detected, resulting in undulation of detected positions as shown in FIG. 3(b). The peak value of the unduration and an angle of rotation at which the peak value is found are determined.

Abstract: A servo controller capable of controlling motors to be driven in different control modes, such as a synchronous motor and an induction motor, irrespectively of the type of the motor, and also capable of carrying out servo control by using incremental feedback signals. A control section common to individual motors and a control section dedicated to each motor are provided in a servo controller. The common control section is always used, while the dedicated control section is selectively used in accordance with the motor to be driven. Thereby, motors each requiring a different control mode can be controlled by the servo controller of one type. The use of th servo controller of one type can reduce maintenance management and a load on a CNC. Also, the provision of the control section common to individual motors can restrain increases of size, installation area and manufacturing cost of the device.

Abstract: An angled illumination tube is capable of reducing a dark spot behind the reflector, while illuminating the tube uniformly over the length of the tube. The tube is used in combination with a light source providing a light beam and comprises an angled transparent tubular conduit having a first end and a second end on opposite longitudinal ends of the conduit. The conduit has a bend between the first and second longitudinal ends, and is used with the first end receiving the light beam from the light source in order to guide the light beam along the length of the conduit. A reflector is disposed within the bend to reflect the light beam from the first end to direct a reflected light beam towards the second end. The reflector defines an incident light axis along which the light beam is guided to the reflector, and a reflected light axis along which the reflected light beam is directed to said second end.

Abstract: A backlash acceleration control method capable of more accurately setting a timing for an initiation for a backlash acceleration correction in a servo system that carries out a feedforward control compared with conventional methods. According to this method, the backlash acceleration correction is initiated at the time when the feedforward amount is reversed from positive to negative or vice versa. Furthermore, this initiation time for the backlash acceleration correction can also be determined according to the point of change of the sign of a speed command modified by the feed forward amount. When the feedforward coefficient becomes close to "1", the positional deviation becomes almost "0", and therefore an actual shift movement comes to follow the shift command without time lag. Accordingly, a point where a shift direction of the shift command is reversed will be dispersed, and so an initiation time for the backlash acceleration correction cannot be determined accurately.

Abstract: A process for the preparation of D-pantolactone, comprising employing specific microorganisms to convert D,L-pantolactone as the starting material into D-pantoic acid by selective asymmetric hydrolysis of the D-form only in the D,L-pantolactone, and then separating D-pantoic acid and converting it into D-pantolactone.

Abstract: A cassette loading/unloading apparatus enables a magnetic recording and reproducing device to be used with both a standard-type tape cassette and a miniature tape cassette without a cassette adapter. When the miniature tape cassette is used, a holding mechanism for the standard-type tape cassette is located at a position where it does not hinder the loading of the miniature tape cassette. When the standard-type tape cassette is used, a holding mechanism for holding the miniature tape cassette is located at a position where it does not hinder the loading of the standard-type tape cassette. Further, only one tape extraction mechanism and only one detection unit for detecting an anti-erasure claw are provided for extracting a magnetic tape from either of the standard type tape cassette and the miniature-tape cassette and for detecting the presence of the anti-erasure claw of either of the two types of tape cassettes.

Abstract: A discrete-type repetitive control unit which enables stable repetitive control even if a state variable of a controlled object is not observable, using time delay elements (Z.sup.-1). The number of time delay elements is equal to or greater than a value obtained by dividing a cycle period of a cyclic target input by a period of sampling the deviation between a controlled object output and the cyclic target input. Periodically applied to each of the time delay elements is a sum obtained by adding the product of the deviation and a first gain (h1, - - - , hn) associated with the time delay element, to the product of an input (u(k)) of the controlled object and a second gain (m1, - - - , mn) associated with the time delay element, and to an output (Wn(n+n), - - - , W1(k+1)) of a preceding element. The control unit periodically applies to the controlled object a sum (u(k)) obtained by adding the product of the deviation and a third gain (h0) to an output (W1(k)) of the last time delay element.
