Title: Measuring method of minute dimension
Inventor: FUJITA HIROO
IPC: G01B11/12
Filed: 1991-01-25
Abstract: PURPOSE:To enable precise measurement of a submicron dimension by a method wherein a laser light is irradiated on a substance to be measured, while it is deflected, and a reflected light in a part of a range including a part of peak intensity is detected for each position of deflection. CONSTITUTION:A laser light 100 from a laser light source 10 is deflected optically by a deflecting optical system 11 and a condensed laser light 130 is emitted to a substance 12 to be measured. A reflected light from the substance 12 to be measured is reflected by a beam splitter 105 and taken out as a reflected light 135. A light sensing element 13 detects the intensity in a part of a range including the peak intensity of the reflected light for each position of deflection, synchronously with a change in the voltage of a deflection control signal 125. When the dimension of a dimension part 21 is denoted by G and beam diameters of the laser light 130 and the reflected light 135 by Di and Dr, a photosensor detects the intensity in a smaller range than DrXG/Di. A pattern preparing element 14 prepares a reflected light intensity pattern representing the relationship between the position of deflection on the surface of the substance 12 to be measured in one period of deflection and the intensity of the reflected light detected by the light sensing element 13. A data processing element 15 processes arithmetically the intensity data on the reflected light intensity pattern, determines edges 210 and 220 of the dimension 21 and calculates the dimension from the amount of deflection between the edges.

Abstract: PURPOSE:To correct the scanning irregularity of an image resulting from the use of a rotary polygon mirror by controlling the frequency of a clock for modulating a laser beam in picture element units according to the check result of the state of a surface to be scanned which is one scan before. CONSTITUTION:One surface of the rotary polygon mirror 22 is scanned with a laser beam of a 1st system and then scanned with a laser beam of a 2nd system.

Further, the voltage outputted by the function generator 58 is added to the output voltage of a DC converter 47 by an adder 55 to generate a 3rd input to the voltage-controlled oscillator 59. Then, the oscillation output 67 of the voltage-controlled oscillator 59 is supplied to a frequency divider 68, a clock 69 which is obtained by frequency division is corrected in response to variation in scanning speed, and an information signal of each picture element is read out in synchronism with the clock 69.

Title: Interruption detecting device
Inventor: URUSHIBATA YUKIO
IPC: G06F9/46
Filed: 1980-03-03
Abstract: PURPOSE: To make the interruption from peripheral device possible independently of pulling-out of boards, by causing the interruption acknowledgement signal from the back and the front to pass before pulling-out of the board even under the state where one of plural boards is pulled out.  
     CONSTITUTION: Respective boards A, B and C are inserted, and connection parts A4, B4 and C4 are grounded. And gates A2, B2 and C2 which are signal passage permitting/rejecting means stop the interruption acknowledegement signal (ACK) which by-passes connection line 7 and is tranferred. If all boards are inserted, ACK is transferred from CPU to the board in response to the interruption request signal (ATN) delivered from a certain board to CPU to perform interruption. If a fault occurs in board B and board B is pulled out, ACK from board disappears; however, since connection part B4 causes signal ACK, which is sent through connection line 7, to pass through signal passage permitting/rejecting means C2 before pulling-out of board B, signal ACK is transferred to board C.
