Title: Ic test system, ion beam tester therefor and method for specifying defective part of ic
Inventor: KURIHARA MASAYUKI
IPC: G01R31/302
Filed: 1994-04-08
Abstract: PURPOSE:To provide a method for specifying the defective part of an IC while enhancing the operability and the image quality. CONSTITUTION:A test pattern generator 200 is provided with means which can set a plurality of patterns for stopping the pattern update operation. Every time when at stop pattern is generated, pattern update operation of the test pattern generator 200 is stopped and a stop signal is delivered to a charged particle ray system 300 in order to acquire an image data. Upon acquisition of image data, an acquisition completion signal generating means 308 transmits an acquisition completion signal and the test pattern generator 200 resumes the pattern update operation. Consequently, different test patterns can be fed alternately to an element to be tested and the image quality can be enhanced by adding or subtracting the image data. Defective part on an IC is specified by differentiating the potential contrast image every time when the logic is different between passed and failed products.

Title: Power circuit of charging equipment
Inventor: TAKANO NOBUHIRO
IPC: H02J7/10
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To stabilize the start-up and switching control of a power supply by putting an output winding for generating the power in phase with an input winding and putting an output winding for generating a resonance signal 180 deg. out of phase with the input winding. SOLUTION: The output voltage generated in a quaternary winding 84 of a high frequency transformer 80 is a flyback voltage just like the output voltage of a secondary winding 82. The values of these voltages are proportional to each other. In order to stabilize the resonance operation, the number of turns of the quaternary winding 84 and the resistance value of a resistor 105 are so adjusted that a feedback terminal 101C of a switching IC 101 may be applied with the voltage higher than the reference voltage of a second comparator when charging a smallest battery pack. On the other hand, a tertiary winding 83 of the high frequency transformer 80 is 180 deg. out of phase with the secondary winding 82 and in phase with a primary winding 81, and so there is only a little influence of the output voltage of the secondary winding 82 on the tertiary winding 83.  By adjusting the voltage of the tertiary winding 83 to the constant voltage which makes the switching IC 101 start up, the voltage applied to a power terminal 101a can be constant.
