Title: Breakdown-strength testing method for bidirectional breakdown-strength circuit element
Inventor: UEHARA HIROYASU
IPC: G01R31/26
Filed: 1990-10-15
Abstract: PURPOSE:To prevent the occurrence of breakdown, deterioration of breakdown strength, bonding breakdown and the like caused by the internal charge in a bidirectional circuit element by discharging the internal charge accumulated in the forward-direction breakdown- strength test, and thereafter conducting the reverse-direction breakdown-strength test. CONSTITUTION:A switch 54 is turned ON, and a testing voltage E<+> is applied on a thyristor 61 from a power supply 51. Then, an ammeter 52 checks leaking current, and the test and measurement of the breakdown strength of the thyristor 61 are conducted. After the measurement, the voltage E<+> is returned to the zero potential, and the switch 54 is turned OFF. Then, switches 71 and 72 are turned ON, and the main current for the circuit operation is supplied from a power supply 73. The trigger current is supplied from a power supply 74. The electric charge accumulated in the N1 layer of the thyristor 61 is discharged. After the end of the discharge, the switches 71 and 72 are turned OFF, and the measurement of the revere-direction breakdown strength is started. After the inverted testing voltage E<-> is applied on the thyristor 61, the measurement and the discharging are conducted by the same way as the measurement of the forward-direction breakdown strength, and the test and measurement are finished. Thus, the occurrence of the breakdown due to the charge accumulated in the N1 layer when the forward-direction breakdown-strength test is changed to the reverse-direction breakdown-strength test can be prevented.

Title: Spike drive device of spike tire
Inventor: OUCHI KIYOYUKI
IPC: B60C11/16
Filed: 1984-12-27
Abstract: PURPOSE:To put in and out spikes according to the presence of ice and snow on a road surface to prevent slip and damage of the road surface by moving forward and backward a slider having a slant wedge surface between a case and a spike member by a drive member made of shape memorizing alloy. CONSTITUTION:When ice and snow are absent on a road surface, a press member 17 made of shape memorizing alloy extends to press a slider 13 against a restoring member 18. Thus, a root 11 of a spike 7 bears against a flat slide surface 14 of the slider 13 and the spike 7 is withdrawn from the tread surface 4 of a tire 3 by a returning spring 22. Thus, the road surface is prevented from damages. On the other hand, when ice and snow are present on the road surface, the press member 17 contracts so that the slider 13 is pressed in the direction reverse to said one by the restoring member 18. Thus, the root 11 of the spike 7 bears against the wedge surface 15 of the slider 13 to project the spike 7 from the tread surface 4 of the tire 4 against the returning spring 22. Thus, the slip can be prevented.

Title: Superconductive magnet for mri apparatus
Inventor: OTA TADATOSHI
IPC: G01R33/3875
Filed: 1989-10-25
Abstract: PURPOSE:To make a leakage magnetic field exert no influence outside a wall even if a counter-bedside of apparatus is set close to the wall, by making the leakage magnetic field asymmetric in Z-axial direction, i.e., smaller in the counter-bedside than in the bedside. CONSTITUTION:A counter-bedside opening phiR of a yoke shield 5 is made smaller than a bedside opening phiF. As a leakage magnetic field from a magnet is more absorbed in the counter-bedside by the aforementioned construction, a shielding effect in the counterbedside is increased and the leakage magnetic field in this side becomes small. That is to say, 5-gauss line of the leakage magnetic field becomes asymmetric to the center O of magnet main body 4 in Z-axial direction. It is possible, therefore, to utilize a diagnosis room 8 efficiently, because a small leakage magnetic field side, the counter-bedside, of the apparatus can be set close to a wall 9 of the diagnosis room 8.
