Title: Method and apparatus for processing probe
Inventor: SUZUKI KATSUYUKI
IPC: G01Q60/02
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To selectively and safely break a lever desired to be broken. SOLUTION: An operator changes the frequency of the voltage signal generated by an oscillator 13 so that the amplitude of the sine wave displayed on an oscilloscope 12 becomes max. That is, the operator adjusts the oscillator 13 so that a lever 3a resonates, and the frequency of the voltage signal applied to a piezoelectric element 7 from the oscillator 13 becomes the intrinsic vibration frequency of the lever 3a. When the lever 3a resonates, the operator makes the amplitude of the voltage signal generated by the oscillator 13 large gradually while keeping the frequency of the voltage signal. Whereupon, the amplitude of the lever 3a becomes further large gradually and, when the bending of the lever 3a exceeds its elastic limit, the lever 3a is broken.

Title: Method for stabilizing characteristic of ferromagnetic tunnel joining element
Inventor: SHIMAZAWA KOJI
IPC: G01R33/09
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent variations of characteristics in practical use of a ferromagnetic tunnel joining element by making the electric current flow to the ferromagnetic tunnel joining element for a specified time before practical use. SOLUTION: A first ferromagnetic film 211 and a second ferromagnetic film 212 are laminated in both sides of an insulating film 210 in a ferromagnetic tunnel joining element (TMR element) 2. The current (i) is made to flow to the TMR element 2 by using a current source A for specified time before practical use. Then the resistant value of the insulating film 210 at the time of practice use is stabilized by previously removing, with an electric shortcircuit (insulation breaking) before practical use, the thin part of the film thickness which brings changes of the resistant value of the insulating film 210 and variations of an output. Thus, variations of the TMR element 2 in practical use are prevented. Although the output value is a little reduced by such a stabilization processing, it is almost negligible in practical use.

Title: Overcurrent protection circuit for semiconductor switch circuit
Inventor: MIKI HIROSHI
IPC: H03K17/56
Filed: 1988-09-22
Abstract: PURPOSE:To protect overcurrent with simple circuit constitution by interrupting a signal given from a drive circuit to a gate-emitter inbetween at the detection of an overcurrent and using a short-circuit so as to short-circuit the gate and the emitter. CONSTITUTION:The overcurrent state is caused when an IGBT (Insulated Gate Bipolar Transistor) 11A is turned on, and when the collector-emitter voltage reaches a voltage of a power supply 5a or over, a transistor(TR) 8a with a current flowing at the normal conduction is turned off. This state is fed back to an ON/OFF signal circuit 13 by a logic gate circuit 20a. The circuit 13 receiving the signal turns off a switch 10c' and turns on a switch 10e. Thus, the gate and emitter of IGBTs 11a, 11b are short-circuited by a resistor 19f and the switch 10e. Thus, the stored charge between the gate and emitter of the IGBT 11a is discharged and the said IGBT 11a is turned off.
