Abstract: PURPOSE:To make it possible to judge the durability of a step nose by fixing a step plate to a jig, and repeating compressing and sliding against the step nose with a compressor. CONSTITUTION:A step-plate fixing tool 2 and a compressor 3 are provided on a base stage 1.

The interval between the step nose 41 and a compressing plate 321 of the compressor 3 is set so that said interval is shorter than the stroke of an air cylinder 33. When the air cylinder 33 is driven and a compressing body 32 is reciprocated back and forth, the compressing plate 321 is slidden upward against the step plate 4 and applies pressure in the moving direction since the compressing plate 321 is attached to a main body 322 in a forward slanting attitude. The compressing plate 321 is formed of a material for the bottom of a slipper having a width of about 10cm based on the width of a human foot. When the compressing and sliding are repeated by the specified number of times, the durability of the step nose 41 can be judged based on the abraded degree of the surface and the presence or absence of scuffing.

Title: Current resonance converter
Inventor: SATO MITSUTAKE
IPC: H02M3/28
Filed: 1990-10-17
Abstract: PURPOSE:To reduce switching noise by generating current resonance between a leakage inductance produced between the primary and secondary windings of a choke coil inserted into the primary side circuit of a transformer and a capacitor connected to the reverse blocking diode of a coil reset circuit. CONSTITUTION:When turning on/off operations are made to an FET 3, an AC voltage is generated on the secondary side of a transformer 2. This AC voltage is converted into a pulsating flow of DC by means of a rectifier circuit 11 and then smoothed to a smooth DC voltage by means of a smoothing circuit 12. A load 31 is connected to the DC voltage. When a direct current is switched to another direct current by means of the FET 3, a current resonance circuit is formed of the leakage inductance 15 of a primary-side choke coil 10 and resonance capacitor 14. As a result, the electric current on the primary side of the transformer 2 becomes a sine wave from which a high-frequency component is eliminated. Therefore, the alternating current induced on the secondary side of the transformer 2 also becomes a sine wave and, since the high-frequency component is eliminated, the DC voltage outputted from the transformer 2 becomes less in noise.
