Title: Pattern detecting device
Inventor: FUSHIMI SATOSHI
IPC: H01J37/22
Filed: 1986-11-14
Abstract: PURPOSE:To enable the full contrast detection of an image of scanning transmission electron beams by selecting outputs of respective photoelectric conversion elements synchronously with the scanning on a scintillator and detecting a fine pattern on a sample by the use of these selective outputs. CONSTITUTION:When scanning transmission electron beams 1b for a sample 5 are scanned on a scintillator 10, diameters of luminous spots formed on respective scanning positions are made smaller than sizes of respective elements of a corresponding photodiode array 15. When a period of repetitive scanning on the scintillator 10 is set longer than afterglow time on the respective scanning positions, outputs of respective elements of the diode array 15, which detects only light spots formed by the use of scanning operations performed synchronously with the scanning on the scintillator 10 at the respective scanning positions so that no aftergrow effect is brought at the adjacent scanning positions and present scanning positions, can be selectively outputted. Hence, a fine pattern on this sample 5 can be detected with high speed and high resolution and without the afterglow effects on the scintillator 10.

Filed: 1990-10-08
Abstract: PURPOSE:To reduce the waiting time of a processor from an input request to an input response by controlling so that the input response held in an input register is read out in the processor by an input instruction executed later than an input starting instruction. CONSTITUTION:When detecting the starting instruction of an input port from a microprocessor 101, a control part 108 outputs the input request corresponding to a bus to an output register 103, and the microprocessor 101 moves to the next process. And when there is a response from an input controller, one of input registers 102 and 107 holds it temporarily, so when the microprocessor 101 executes the original input instruction, the control part 108 informs of the response immediately. Thus, the waiting time of the processor 101 from the input request to the input response is reduced.

Abstract: PURPOSE:To make it possible to measure a charge current simply and accurately, by performing corona discharge to a pair of auxiliary electrodes and main electrodes in such a state that both auxiliary electrodes are earthed and measuring the charge current flowing to the main electrodes. CONSTITUTION:When voltage is applied to a charger 6a in such a state that switches SW1-SW3 are opened, the discharge from the part having a length l1 of a wire 8a is performed to main electrodes 2a, 2b to accumulate charge in the electrodes 2a, 2b. The corona discharge from the part shifted from the length l1 of the wire 8a is performed to auxiliary electrodes 5a, 5b but, because electrodes 5a, 5b are earthed, no charge is accumulated in the electrodes 5a, 5b to exert no effect on the charge accumulated in the electrodes 2a, 2b. When the switch SW1 or SW2 is closed in this state, the charge accumulated in the electrode 2a or 2b is earthed and a current value is detected by a detector 7. After the inclination of the charger 6a is adjusted so as to make the current values of both of them equal, the charge is accumulated in the electrodes 2a, 2b and, when the switch SW3 is closed, the sum current of the electrodes 2a, 2b is detected by the detector 7.

Abstract: PURPOSE: To realize stable oscillation of a fundamental wave by specifying average surface roughness of at least a major side vibration electrode forming part of a crystal plate to suppress harmonic spurious radiation such as the third overtone. CONSTITUTION: Average surface roughness of at least a major side exciting electrode forming part of a crystal plate whose front side and rear side are formed with a exciting electrode is selected to be 4-20μm.

Title: Digital-analog converter
Inventor: HASHIDO RYUICHI
IPC: H03M1/74
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To reduce the error from a design value with good responsibility by driving capacitance area larger than reference capacitance in a capacitance group by the area of the reference capacitance. SOLUTION: The area and capacity values of capacitance elements 41 and 42 are equalized to the reference capacitance 3 with capacity C2 and they are connected in parallel to obtain total capacity C3=2×C2. The area and capacity values of capacitance elements 51 to 54 are also equalized to the reference capacitance 3 with the capacity C2 and they are connected in parallel to obtain total capacity C4=4×C2. Similarly, the total capacity C5 of capacitance elements 61 to 68 is 8×C2. Consequently, if a process error is generated, the errors in output voltage from the design value is made less than before.  Therefore, the division number is increased twice by twice as the capacitance area increases, but the deviation of the output voltage of DAC from the design value becomes less than before in principle on condition that variation in area corresponding to the process error is larger than the area ratio.
