Title: Current chopping system for switching type reluctance machine
Inventor: SUTEFUAN RICHIYAADO MAKUMIN
IPC: H02P6/06
Filed: 1990-05-11
Abstract: PURPOSE: To reduce a switching loss by controlling the switching elements of an inverter comprising a plurality of switching elements connected in series with corresponding phase windings thereby regulating the current. CONSTITUTION: In an inverter 55 comprising two switching elements 35, 38 connected in series with respective phase windings 32a, 32b, both switching elements 35, 38 are turned on at the start of conduction period of respective phase. At a moment of time when the current from a DC power supply reaches the upper limit of a hysteresis band, preselected one of the switchinq elements 35, 38 is turned off while the other is sustained in the on state. A phase current ISENSE circulates through the other switching elements 35, 38 and corresponding flyback diodes 44, 47. When the phase current ISENSE attenuates to the lower limit of hysteresis band, selected one of the switching elements 35, 38 is turned on again.

Title: Bound preventing device of automatic diaphragm
Inventor: TANAKA OSAMU
IPC: G03B9/02
Filed: 1983-07-01
Abstract: PURPOSE:To prevent a bound by providing a detaining lever which turns centering around a position separated from the center of gravity of itself, on an operating member for constituting a diaphragm operating means of a diaphragm blade, so that the detaining lever turns and collides with a collision receiving part when the diaphragm operating means stops suddenly. CONSTITUTION:When a release operation is executed, a diaphragm interlocking lever 12 moves, and a diaphragm lever 6 turns clockwise centering around a shaft 9 together with a diaphragm interlocking pin 5 and a bound detaining lever 13 by an energizing force of a spring 11. As a result, a diaphragm operating plate 3 turns and a stopping-down is executed. When a cam abuting pin 7 collides with a diaphragm cam 8, the diaphragm lever 6 stops suddenly, but the bound detaining lever generates a rotational force since the center of gravity is separated from a shaft 17, turns suddenly clockwise, and the tip collides with the inside surface of a lens barrel fixing part 20. In this case, at a collision position Q, the bound detaining lever 13 is brought into press-contact strongly with the lens barrel fixing part 20 by a pressure angle shown by phi, and the collision position Q is not varied. In such a way, a bound can be prevented effectively irrespective of a set diaphragm value and a stopping-down transfer means.
