Title: Optical disk reproducing device
Inventor: IWAZAWA MAKOTO
IPC: G11B19/247
Filed: 1988-02-19
Abstract: PURPOSE:To reduce the cost of an optical disk reproducing device by actuating a disk driving means in such a way that, after the control of the disk driving means is performed by using synchronizing signals of a low frequency, the synchronizing signals are switched to another synchronizing signals of a high frequency and the disk driving means is actuated by using the high-frequency synchronizing signals. CONSTITUTION:A control switching means 27 which switches synchronizing signals of a low frequency to another synchronizing signals of a high frequency so that a disk driving means 23 can be actuated by means of the high-frequency synchronizing signals after the means 23 is controlled by a rotating speed controlling means 26 based on the low-frequency synchronizing signals when the disk driving means 23 is actuated, is provided. Therefore, without using a rotating speed signal generating means composed of a frequency generator and rotating speed detecting/comparing circuit, etc., the disk driving means 23 can be actuated at a stable rotating speed and, moreover, highly accurate rotating speed control can surely be carried out in accordance with the high-frequency synchronizing signals. As a result, the cost of the optical disk device can be reduced.

Title: High-frequency heater
Inventor: IWABUCHI YASUSHI
IPC: A47J37/00
Filed: 1988-02-22
Abstract: PURPOSE:To allow the rotation of a kneading blade to be alternated in the two opposite directions as desired in order to improve the kneading power by molding into one jointless piece a movable piece comprising a tapering part on which the movable piece itself is pushed up, a stop which prevents a baking pan from being dislocated from the bottom of the heating chamber, and a spring holder which holds in place a spring pressing the movable piece down. CONSTITUTION:As a means of preventing a baking pan from being dislocated when a kneading blade is rotated in reverse during kneading, there is provided a reverse preventing device which is attained to a support and in which a movable piece is caught on a catch when the kneading blade is turned in reverse. Said movable piece consists of one jointless piece which structurally comprises a tapering part 69a on which, when the baking pan is fixed to the bottom of the heating chamber by turning, the movable piece is pushed up as it slides on the catch, a stop edge 69b which, when the kneading blade is turned in reverse, is caught on a side of the catch so as to prevent the baking pan from being dislocated from the bottom of the heating chamber, and a spring holder 69c which holds in place a compression spring 68 pressing the movable piece down. This reverse preventing device makes it easy to mount and dismount the baking pan and prevents it from being dislocated during kneading, hence allowing the rotation of the kneading blade to be alternated in direction as desired so that the kneading power can be improved even in such difficult cases of kneading as the use of a cubic pan.

Filed: 1982-03-12
Abstract: PURPOSE:To avoid a control operation in error based on a mistaken output data, by performing the parity check of the output data transmitted from a controller main body. CONSTITUTION:In transmitting the output data of an input and output device from a controller main body, a left serial data input/output terminal SDL is connected to a serial input terminal SI of a shift register 14, and a serial output terminal Q5 of the register 14 is connected to a right serial data input terminal SDR.

Title: Controlling method for drive of dc motor
Inventor: KATAOKA KEIGO
IPC: H02P7/06
Filed: 1981-03-18
Abstract: PURPOSE:To improve the proportional accuracy of a DC motor by correcting the speed reference signal with a voltage drop amont compensating signal of a armature circuit and a compensating signal proportional to the product of the armature current and the speed reference. CONSTITUTION:A speed reference signal 3a is inputted through a voltage regulating resistor Rb and a resistor R3 to a multiplier 40, and is multiplied by an armature current signal 3b through a resistor R4. The output of the multiplier 40 becomes a signal 3d through a resistor R5. The signal 3d is added to a signal 3e obtained by the armature current signal 3b and a resistor Ra, thereby correcting the signal 3a to obtain a reference signal. An arithmetic unit 30 compares and calculates a voltage feedback signal 3c with the reference signal and produces the difference. In this manner, the proportional accuracy can be improved and the stable operation can be performed.

Title: Speed compensating device of rolling mill
Inventor: NOGUCHI MASAHARU
IPC: H02P29/00
Filed: 1981-03-18
Abstract: PURPOSE:To provide a speed compensating device of a rolling mill capable of avoiding the generation of compressive force, by constituting a titled device which controls the torque of a motor so as to follow up the change of a loading torque of the mill when biting a rolling material. CONSTITUTION:When a rolling material 1 is bitten by a rolling mill 3, a switch 22 closes, and an output DELTAX2 of an operating circuit 21 is inputted to a conversion circuit 23 to add an output DELTAVREF=DELTAX2/G1 of the circuit 23 to a speed standard VREF. Accordingly, an output X2 of a speed controlling circuit 11 changes by DELTAX2, and an output X2 of a current controlling circuit 12 changes rapidly responding to the change DELTAX2 when the input X2 changes by DELTAX2, because the response of the circuit 12 is rapid enough. As the output X2 of the circuit 12 corresponds to an armature current of a motor 5, the armature current of the motor 5 changes rapidly responding to the load change simultaneously with a biting of the material 1 by the mill 3. That is, when the mill bites the material 1, the driving torque of the motor changes rapidly following up the load variation at the same time, thus the ideal impact-drop compensation is performed.

Abstract: PURPOSE:To cut a pipe in high efficiency with no material loss, by cutting the tapered central part which is formed in the pipe fed in a predetermined length by pressing a drawing roller tapered so that the nearer is a position of its peripheral surface approaching the both end parts in the axial direction from the central part of the peripheral surface the smaller an external diameter of the roller decreases. CONSTITUTION:A pipe 5, being clamped by a chuck 1, is rotated. While drawing rollers 2a, 2b symmetrically provide tapers 20a, 20a, 20b, 20b so that the nearer approaches a position of the peripheral surface of the roller to its both end parts from the central part in the axial direction of the peripheral surface the smaller an external diameter of the roller decreases, and a tilt angle theta1 of said taper is equalized to the tilt surface of a tapered thread formed by a chaser in manufacture of a pipe nipple. When the pipe 5 is cut, a cutter 3, being lowered and pressing the central part between tapers 51, 51 formed in the pipe 5 while it is rotated, cuts the central part. A cut piece of the pipe, being fed out in the direction of an arrow head H in the drawing, applies tapered thread cutting to the both end tapers 51, 51 by the chaser.
