Title: Driving circuit for stepping motor
Inventor: MATSUSHITA TAKESHI
IPC: H02P8/30
Filed: 1981-03-31
Abstract: PURPOSE:To reduce the power source, to omit a power resistor and to reduce the size and power of a stepping motor by composing of an oscillator capable of varying the duty ratio of the oscillation output waveform and a switching circuit. CONSTITUTION:An oscillator 1 capable of varying the duty ratio of the oscillation output waveform, a switching circuit 2, and the coil 3 of a stepping motor are provided, and a switch SW in a view showing the operation principle corresponds to a transistor Q5 and a diode D1. When a switch SW is connected to the E side, a current flows from the power source E1. When the switch is connected to D side, the current flows from the ground to the coil of the motor as designated by an arrow. In this case, since the saturated value of the current is represented by E/R, the average current flowing through the coil becomes a value proportional to the duty ratio, and the average current is represented by the product of the saturated current value and the duty ratio. In this manner, when the duty ratio of the waveform presented at the point D is regulated, suitable excitation current can be obtained.

Title: Coordinate value checking circuit
Inventor: WAKAZONO SHIGEO
IPC: G06F3/0488
Filed: 1979-04-20
Abstract: PURPOSE: To avoid sending the erroneous data to the processor by disregarding the erroneous data in case the continuous coordinate value is read out mistakenly, thus omitting the data check at the processor.  
     CONSTITUTION: Reading data 10 of the coordinate value read out first is stored into the 1st register 11 via reading pulse 14 which is supplied simultaneously. Then data 10 stored in register 11 is stored into the 2nd register 12 via the reading pulse which is delayed by the fixed time through delay circuits 15 and 16. The comparison is given through comparator 13 between reading data 10 of the coordinate value which is supplied continuously and reading data 10 which was read precedingly and stored into register 12. And in case the difference of the absolute values is within the fixed range, the logic product of AND gate circuit 17 is set up by the output of comparator 13 to deliver data strobe pulse 18. While in case the difference of the absolute values exceeds the fixed range, the logic product of circuit 17 is not set up. Thus the transmission of the erroneous data is inhibited to the processor.

Title: Sample inclination observing method in scanning charged particle beam system
Inventor: YAMADA ATSUSHI
IPC: H01J37/22
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a sample inclination observing method in a scanning charged particle beam system, allowing image observation by eliminating dislocation of an observation position during sample inclination. SOLUTION: The height position of a sample is determined by an automatic focus function after sample exchange and a difference between this determined height position, and a true eucentric height position is determined. Based upon this difference, a CPU 16 performs conversion processing according to a formula, a correction table, or the like stored in advance and calculates a moving amount of an image in an X-direction with regard to an inclination of the sample. The obtained moving amount in the X-direction is provided to an image shift coil 17 via an image shift driving circuit 18 by the CPU 16. The image shift soil 17 deflects an electron beam EB and moves an observation visual field by the amount dislocated by the inclination. Thus, a movement of the observation visual field due to the inclination of the sample is corrected, even when the sample is not set at a standard height position to enable an observer to observe a screen without visual field movement.

Title: Providing method for basic pile for construction of continuous underground wall
Inventor: HOTSUTA HISANORI
IPC: E02D5/50
Filed: 1979-04-19
Abstract: PURPOSE: To raise the efficiency of execution of works and attain high accuracy of a basic pile by positioning the pile so that it has a constitution resistive to the lateral pressure in the range where the lateral pressure is unchangeable.  
     CONSTITUTION: The range A where the lateral pressure is changeable and the range B where the lateral pressure is unchangeable are ascertained beforehand, while a pile 2 is constituted so that it can endure the lateral pressure of gravel 4 in the range B. The pile 2 is built in a vertical hole 1 and then the gravel 4 is thrown in the space between both sides of the pile 2 and the inside wall 3 of the vertical hole, thereby the position of the pile 2 being decided. Since the gravel 4 is thrown in inside of a cutoff sheet 12 and others, it is impossible that the concrete struck later in a space 6 should mix in the gravel 4. In addition, the gravel can be thrown in at one operation irrespective of the striking of the concrete in a central hollow part 5. A continuous underground wall is constructed by digging a groove by a clamshell bucket, being guided by the web 9 of the pile 2, and pouring the concrete in the groove.
