Patent JP-H08317667-A (JP)
Title: Control circuit for pwm converter
Inventor: KATSURAYAMA NORIYUKI
IPC: H02M7/48
Filed: 1995-05-22
Abstract: PURPOSE: To obtain a control circuit which can prevent the damage of a switching element by a method wherein, when the state of a DC power-supply voltage is detected and an AC input current is zero, the drive of the switching element at a PWM converter is stopped. CONSTITUTION: When a power interruption occurs in a power running state, a voltage cannot be raised. As a result, the value of a voltage instruction V* cannot be maintained so as to be dropped. When a DC voltage becomes a voltage detection level V1 for power running or lower, the comparison signal of a DC-voltage comparison circuit (DC) 14 is output, and a power interruption detection circuit (PS) 15 checks an input current. When the output of the DC 14 is generated by the power supply cutoff, the input current is zero, and the PS 15 stops the operating signal of a PWM converter. When an AC power supply in a regenerative state is cut off, electric power from a load 5 is accumulated, and a DC voltage is raised.  Consequently, when the DC voltage becomes larger than a regenerative-voltage detection level V2 which is set to be higher than the voltage instruction V*, it is detected, the existence of the input current at this time is confirmed, and whether the power interruption exists or not is judged.

Abstract: PURPOSE:To obtain an apparatus for measuring coordinates which reduces the cost and prevents deterioration of precision in measurement and deficiency of the strength of a surface plate. CONSTITUTION:A pair of leg parts 54A and 54C of a support member 54 provided along the opposite side parts of a surface plate 64 are joined by an arm 54B, and one leg part 54A is provided for a right-side Y column 52A of a Y carriage 52. A reference air pad 66 of the leg part 54A is supported movably along one side face of the surface plate 64, while an air pad 70 for a counter force provided movably for the other leg part 54C is biased by a prescribed biasing force onto the other side face of the surface plate 64 by a coned disk spring 69. Moreover, a leaf spring 76 joins a left-side Y column 52B of the Y carriage 52 and the leg part 54C of the support member 54 together, while absorbing the thermal deformation of the support member 54. Accordingly, it is unnecessary to fit a guide member directly to the surface plate 64 and to make a groove for guide by machining directly in the surface plate 64.

Abstract: PURPOSE:To drastically reduce the initial wear of the surface of a roll at the time of rolling by sprinkling water on the surface of a roll, dulling it by laser beam through a thin water film before electroplating it, then, plating it with chrome. CONSTITUTION:For preventing a softened austenite phase from remaining on the projecting surface layer of the surface of a roll 1 roughened by laser beam machining, a spray water nozzle 5 is equipped on the lower part of a work head 4 where a convergent lens 3 of laser beam is built in, water of 10-100ml/min is sprinkled on the surface of the roll 1 as it is rotated, to form a thin water film and the surface of the roll is irradiated with laser beam through a water film and dulled. Then, the surface of the roll is dipped in chromic acid solution through degreasing, cleaning, electric etching and electroplated with 2-15mum chrome. In this way, separation of plated chrome is prevented during the rolling and the life of the roll is improved drastically.

Title: Generating brake device of electric railcar
Inventor: OKAMOTO KENICHI
IPC: B60L7/04
Filed: 1984-06-14
Abstract: PURPOSE:To shorten the idling time from the detection of slipping to the readhesion by reversely exciting one series motor group if a slipping occurs when the series motor group is cross-connected in parallel to operate as generators. CONSTITUTION:When a running electric railcar is decelerated by generatively braking, the first and second series motors in which armatures 11A, 21A and field windings 11F, 21F are connected in series are cross-connected in parallel, and a brake resistor 8 is connected between connecting points of the armatures and the field windings of the both motors. When a slipping occurs during generatively braking, contactors 27A, 27B are closed to reversely flow the current of the winding 21F, thereby abruptly increasing the brake torques of the both motors. If the reverse excitation is continued as it is, the brake torque is again increased after the slipping is eliminated.
