Filed: 1995-02-16
Abstract: PURPOSE: To provide a load drive apparatus by which an irregularity in the offset of a load drive operation due to an irregularity in a drive transistor and an irregularity in a gain are suppressed. CONSTITUTION: The polarity of an input signal Vi is removed in an absolute value circuit 1, and the input signal is converted into a current Ii by an input V/I circuit 2.

The current Ii is subtracted from the output of a feedback V/I circuit 8 in a subtracter 4, and it is changed into a voltage by an I/V circuit 9. A PWM conversion circuit decides pairs of transistors 6a to 6d driven by a drive circuit 6 on the basis of the polarity signal Sp and of the output of the I/V circuit 9. At this time, a feedback current If is generated by converting the output of a drive voltage detection circuit 7 into a current.  At this time, as a ground neutral point for a current conversion operation, a point B or a point C at both ends of a load is selected by a changeover circuit 11 on the basis of the polarity signal Sp.

Abstract: PURPOSE:To achieve a highly sensitive measurement with a small amount of sample with a small area by installing a film retained at a flange by isolating a gas exposure container and a vacuum container hydromechanically and allowing the vacuum container to have a mass analyzer. CONSTITUTION:A flange 11 for retaining film isolate a 985 exposure container 12 from a vacuum container 13 hydromechanically.

Abstract: PROBLEM TO BE SOLVED: To accelerate a processing by preparing a table based on the result of arithmetically evaluating the feature vector and reference vector of a pattern for learning and selecting the candidates of a category based on an arithmetic result using the feature vector of a recognition object pattern and the reference vector of the pattern for learning. SOLUTION: The table 2c is prepared based on the result of arithmetically evaluating the feature vector and reference vector of the pattern 1 for learning. A classification part 2d performs the large classification of the recognition object pattern 3 by using the reference vector 2a prepared from the pattern 1 for learning, attached information 2b and the table 2c. In the classification part 2d, several hundred categories which appear to be a correct answer are selected from the huge number of the categories such as KANJI(Chinese characters) for instance. Then, in a detail identification part 4, by selecting a first order from the classified several hundred categories, a recognized result 5 is obtained. Thus, since a processing amount does not depend on the category number of the pattern to be recognized, the processing is accelerated.
