Title: Automatic positioning method of billet cutter
Inventor: IWABUCHI OSAMU
IPC: B22D11/16
Filed: 1983-02-10
Abstract: PURPOSE:To maintain always the specified cutting length of a billet irrespectively of the stand-by position of a cutting carriage which travels synchronously with the casting speed of the billet by detecting the position of the cutting carriage and the casting speed and controlling the casting speed according to the detected position. CONSTITUTION:A pulse oscillator 16 for detecting position to be operated by a switch LS1 for detecting the stand-by position of a cutting carriage 1 as a starting point is provided and the position signal of the carriage is outputted therefrom. The casting speed signal of a billet 15 detected by a detector 19 of a pinch roll 4 and the casting width signal by a casting device are outputted. These signals are inputted respectively to an arithmetic circuit. The circuit calculates the extent of the movement La of the carriage required since the start of cutting till the completion thereof, the moving time Ta for assuring said extent, and the time Tb until the prescribed cutting position of the billet arrives at the carriage position moved by the extent La upon completion of the cutting, compares the times Ta and Tb, changes the casting speed when Ta>=Tb and maintaines the casting speed when Ta<Tb. The cutting length of the billet is maintained always constant irrespectively of the stand-by position of the carriage by the above-mentioned method.

Filed: 1985-02-06
Abstract: PURPOSE:To improve the degree of freedom of the laying of a wiring for a signal by forming a wiring-width reducing section to the longitudinal intermediate section of a power-supply-feed wiring and laying the wiring fo the signal consisting of the same wiring layer as the power-supply-feed wiring into a minimum rectangular region containing one power-supply-feed wiring region corresponding to the reducing section in an internal cell array region. CONSTITUTION:Minimum rectangular regions 12-20, width thereof is reduced, are shaped to the longitudinal intermediate sections of power-supply-feed wirings 3-11. Consequently, currents flowing through the power-supply-feed wiring 7 minimize with a proceeding toward the upper sections of fundamental cells 1 positioned at the center of an internal cell array region 2, and minimum necessary wiring width is narrowed toward the center. As a result, the wiring width of the power-supply-feed wiring 7 is brought to 100mum on first - fourth line and thirteen - sixteen line fundamental cells 1 in the internal cell array region 2, both sides are reducedat every 10mum on fifth - twelvth line fundamental cells 1, and a wiring channel for laying wirings for signals set at 10mum pitches is increased to the wiring 7 in the minimum rectangular region 16. Accordingly, the degree of freedom of the laying of the wirings for the signals at the central section of the internal cell array region can be made effectively larger than that of laying in a peripheral section.

The product falls into a product punched hole by own weight and is positioned. Thus, ejection and transfer of a product by a sucking means is easily and positively performed, so that continuous punching work is performable.

Title: Detecting equipment of precursory phenomenon of quenching of superconductive magnet
Inventor: YONEYAMA TAKAO
IPC: H01F6/02
Filed: 1983-02-15
Abstract: PURPOSE:To detect a quenching phenomenon beforehand by a method wherein a sound detecting element is attached to a superconductive magnet and the case, in which the detecting signal does not exist for longer than a pre-determined period while an applied current is being increased, is detected. CONSTITUTION:A sound generating element 21 for generating dummy sound signal is attached to an electrode part or a main part of a superconductive magnet 1. The sound signal generating element 21 is driven by periodical pulses from a pulser 20 and transfers a sound signal to a sound detecting element 2 through the magnet 1. The sound signal, given from the generating circuit 21 by the detecting element 2 is detected by a circuit 10 and compared with a threshold value by a comparing circuit 22 and converted into a pulse signal. When generating interval of these pulse signals becomes longer than a pre-determined period while a current applied to the superconductive magnet 1 is being increased, an AND circuit 24 produces an output and a quenching phenomenon is detected. When the quenching phenomenon is generated, a current breaking circuit 5 disconnects a source 6 from the magnet 1.

When the 1st preliminary bending is completed, the 2nd preliminary bending of the flange part is performed by the 2nd preliminary bending surface 51b. In the 2nd preliminary bending B, the flange part 21a is bent to the side of the inner panel 22 so that the vertical wall of the flange part 21a is pressed to a specified site. The shape of the vertical wall of the flange part 21a is formed into a desired shape after the shape of prescribed site of a lower die. The top part of the preliminarily bent flange part is pressed by an upward bending edge 61 to the inner panel to complete the working.

Title: Inverter device

Filed: 1980-02-25
Abstract: PURPOSE:To reduce the ratio of harmonic wave content of the 3-phase AC voltage waveform of an inverter device by always comparing the 3-phase AC voltage of the respective output terminals between the phases with a copy reference signal and feeding back the compared result to the switching control terminal of a main inverter circuit. CONSTITUTION:3-Phase AC voltages (the output waveforms of filters 7-9) between the output terminals U and V, V and W, W and U of the three phases are always compared with a copy reference signal, and the compared signal is fed back to a main circuit (such as BU2). Since the variation in the counterelectromotive force generated from a motor corresponds to the operation of a control circuit in this manner, the 3-phase AC voltage waveforms applied to the motor are stabilized to eliminate the occurrence of deformation in the waveform of the conventional device. Accordingly, the ratio of harmonic wave content of the 3-phase AC voltage waveforms can be reduced at the time of varying the counterelectromotive force generated from the motor.

Title: Coating for detecting no or weak magnetic force
Inventor: OYA MASAYUKI
IPC: C09D5/24
Filed: 1988-02-04
Abstract: PURPOSE:To obtain a coating for detecting no weak magnetic force, which can be perceived visually, by a construction wherein a fine-powder-form substance having a superconducting characteristic is mixed in a substance having a property of sticking to another body. CONSTITUTION:A coating constructed by a method wherein a fine-powder-form sub stance having a superconducting characteristic is mixed in a substance having a prop erty of sticking to another body is applied widely on the whole, irrespective of the presence or absence of lines of magnetic force, including a part on and near a magnet 1 where the lines of magnetic force are strong. Together with this application, the coated part is cooled down to a critical temperature of superconduction or below. Then a minus effect takes place in this coating and mutual repulsion occurs in a part wherein a magnetic force exists. Therefore, it is hard for the coating to be present in the part wherein the magnetic force is strong, and thus it is shifted to a place where the magnetic force is absent. As the result, the coating is gathered in a place where the lines of magnetic force are weak, that is, only in a part denoted by a numeral 3. By the residual existence, accordingly, it is made possible to visualize the lines of magnetic force. In this case, however, the coating is colored so that the presence thereof can be perceived visually.
