Title: Crown control method for multistage rolling mill
Inventor: NAKAYAMA TADAO
IPC: B21B37/28
Filed: 1986-11-21
Abstract: PURPOSE:To improve the shape control accuracy by installing plural rolling reaction sensors at the back of a support roll and giving a work roll a mechanical crown by properly shifting the support roll in the orthogonal direction to the axis of the support roll. CONSTITUTION:Plural rolling reaction sensors 5 and pressing means 6 are installed between a central support roll 3 and a housing 4 in the direction along the roll axis. The pressing means 6 are composed of a couple of slidable wedge- shaped members and others and shift the support roll 3 in the orthogonal direction to the axis by retracting one of the wedge-shaped members through driving of a motor 7. When a thermal crown of the roll 3 generates during rolling, the rolling reactions detected by the sensors 5 cause a comparator 8 to output an error signal and the means 6 automatically control a crown of the work roll 1. The shape control accuracy is improved because the rolling reactions are controlled to be constant.

Title: Electric resistance welding method
Inventor: TANAKA KAZUO
IPC: B23K11/20
Filed: 1984-12-28
Abstract: PURPOSE:To join securely a high-conductivity material and low-conductivity material by resistance welding while preventing the temp. elevation and welding of the contact surface between electrodes and an insert material owing to the smaller tendency of the insert material to heat generation by interposing the high-conductivity material between the low conductivity material and the electrode in the resistance welding stage of the high-conductivity material and low-conductivity material. CONSTITUTION:The high-conductivity material 1 and the low-conductivity material 2 are superposed in the electric resistance welding stage of the two materials. The high-conductivity material 5 is then pressed to the bottom surface of the material 2 to form a 3-layered construction and thereafter the materials are sandwiched by the electrodes 3, 4 from above and below and welding current is passed between the electrode 3 and the electrode 4 while the materials are pressed. Then mainly the material 2 generates heat and the contact surface 6 between the material 2 and the material 1 as well as the contact surface 7 between the material 6 as well as the material 5 are respectively fused to each other. Since the materials 1 and 5 generate heat to the smaller extent, the welding of said materials to the contact surface 8 with the electrode 3 or 4 and the contact surface 9 does not arise.

IPC: G01S13/58
Filed: 1995-10-26
Abstract: PURPOSE: To accurately specify the information of a target by accurately setting the combination of beat frequencies even when a plurality of targets having relative speeds exist. CONSTITUTION: A microcomputer 10 selects the beat frequencies corresponding to the rising part side and falling part side of modulated signals from a D/A converter 20 from the beat signal of a mixer 60. Then the microcomputer 10 obtains a combined beat frequency by combining one beat frequency on the rising part side with one beat frequency on the falling part side and predicts future combined beat frequencies at regular time intervals based on the combined beat frequency. When the predicted combined beat frequencies exist in the beat frequencies on the rising and falling part sides selected at the regular time intervals or in the vicinities of the frequencies, the existing predicted combined frequencies are set as true combined beat frequencies and the information about a target is accurately specified based on the true combined beat frequencies.

Title: Controller for induction motor by pulse-width-modulation inverter
Inventor: TANAMACHI TOKUNOSUKE
IPC: H02P27/08
Filed: 1991-10-25
Abstract: PURPOSE:To decrease a variation and to eliminate a phase deviation of a basic wave by generating a voltage between three pulse lines of one pulse disposed at a center and two pulses disposed at both outsides when the number of pulses included in a half cycle of an output voltage of an inverter is three. CONSTITUTION:512 of carrier generating means 51 normally generates V- and W-phase inverted trapezoidal waves. 511 of modulation wave generating means 52 normally generates U-, V-and W-phase square waves. The square waves are compared with the inverted trapezoidal waves by comparing means 53, which outputs pulses for control switching elements UP, VP, WP. As a result, the output voltage (between U and V) waveform of an inverter 2 has three pulses, i.e., one pulse disposed at a center of 120 deg. of a width and two pulses disposed at both outsides of 120 deg. of the width. The output voltage of the inverter 2 is controlled by varying the peak value of the square wave according to an output Vc of a modulation factor calculator 10 with respect to an output frequency (f).

Title: Trimmer capacitor
Inventor: MATSUSHITA OSAMU
IPC: H01G5/01
Filed: 1989-10-26
Abstract: PURPOSE:To prevent the inferiority of the capacity variability of a capacitor by the backlash of a stator by providing a straight part for whirl stopping at the periphery of the stator, and forming a straight part corresponding to this straight part at the bottom of a case. CONSTITUTION:A straight part 4b is made at one part of the periphery, and another straight part 1b is made at the bottom of a case 1 corresponding to the straight part 4b. Hereby, if one makes the columnar part 2a pierce the hole 4a of the stator 4, the straight part 4b is installed on the bottom face along the slant of the straight part 1a. Since the straight parts 4b and 1a abut on each other in this condition, even if one turns a driver plate 7, the stator does not rotate. Accordingly, the inferiority of the capacity variability of a capacitor by the backlash of the stator can be prevented, and the capacitor's capacity can be varied properly.
