Title: Overvoltage detecting circuit for induction motor power supply device
Inventor: SAKUMA ARATA
IPC: H02P3/18
Filed: 1990-04-06
Abstract: PURPOSE:To simlify the structure of the title circuit and reduce the price of the same by a method wherein an AC voltage at the connecting side of an induction motor for a PWN inverter is reduced by an insulating transformer and an overvoltage is detected by the secondary voltage of said insulating transformer. CONSTITUTION:In the driving device of an induction motor 5 driven by a PWM inverter 4, an insulating transformer 6 is provided at the induction motor 5 connecting side of the PWM inverter 4. The transformer 6 reduces the primary side voltage 102 of the degree of several hundred volt into the secondary side voltage 103 of the degree of several volt. A detecting voltage rectifier 7 rectifies a voltage signal 103 and outputs it into a comparator 8 as a voltage signal 104. The output signal 101 of the comparator 8 is 'Low' upon normal time. The output signal 101 is changed from 'Low' into 'High' by the generation of an overvoltage and stopping command is outputted. A control circuit is constituted of low-voltage instruments in such manner. whereby an insulating strength to ground can be reduced and the price of employing instruments becomes inexpensive.

Title: Slab cooling method after continuous casting
Inventor: FUKUTANI KAZUHIKO
IPC: C21D9/00
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To efficiently and surely cool high-temp. slabs after continuous casting with a simple equipment by laminating plural sheets of the high-temp. slabs, subjecting the front surface of the uppermost stage slab to a water drop adhesion preventive procedure and spraying cooling water to both side surfaces in the longitudinal direction of the high-temp. slabs. SOLUTION: The front surface of the uppermost stage of the laminated high-temp. slabs is subjected to the water drop adhesion preventive procedure and the cooling water is sprayed to the both side surfaces in the longitudinal direction of the slab, thereby, the cooling by adhesion of water drops onto the front surface of the slab of the uppermost stage is prevented and the temp. difference between the front and rear surfaces of this slab is eliminated. The occurrence of the warpage of the slabs is thus prevented. There is no occurrence of a clearance between the rear surface of this slab and the front surface of the slab under the same and the warpage of the slab thereunder may be prevented.  While the warpage of the slabs is prevented in such a manner, the cooling water is sprayed to both flanks in the longitudinal direction of the slabs and the cooling is progressed from both flanks in the longitudinal direction to the central part. The entire part of the laminated high-temp. slabs is thus cooled. Planar refractories, such as thick steel plates, may be used as the water drop adhesion preventive material.

Abstract: PURPOSE:To enable to perform continuous and self-control of measurement of wide-ranged discharge, by installing a discharge control switching device which automatically switches discharges of two systems of a large-sized and a small- sized system by means of a given discharge threshold. CONSTITUTION:When a discharge set signal S increases and discharge of a main line 10 increases and attains a given value, an alarm setter 44 actuates to output a pulse signal.
