Abstract: PURPOSE: To perform recording at a desired time and record the count value of control pulses at the start and the end of this recording, by providing a timer mechanism to store the start time and the end time of the timer operation.  
     CONSTITUTION: RAM13 is provided with a timer memory, and every two addresses are paired to store the start time and the end time of the time operation. First, timer data in the first address of the timer memory is read out; and when this data agrees with the count value of a clock signal, the recording state is set. Simultaneously, the count value of control pulses at this time is stored in the program memory of RAM13. When the recording state is set, timer data in the second address of the timer memory is read out; and when this data agrees with the count value of the clock signal, the stop state is set. Simultaneously, the count value of control pulses at this time is stored in the program memory. These operations are repeated prescribed-number times. Programs for these operations are stored in ROM12.

Title: Radar equipment
Inventor: SEO TAKESHI
IPC: G01S7/42
Filed: 1989-02-17
Abstract: PURPOSE:To improve total performance of a radar by providing two pairs of phased-array antennas having vertical polarization characteristic and phased- array antennas having horizontal polarization characteristic which are paired and whose back surfaces are opposed to each other. CONSTITUTION:In the case of reception, vertical polarization electric wave radiated from the 1st phased-array antenna is reflected on a target and made incident on the 1st phased-array antenna. Then it passes through the terminals 5a and 5c of a switch 5, is amplified in a receiver 9 and transmitted to a signal processing device 19. On the other hand, the level received by the 2nd phased- array antenna is suppressed by the amount of sum of difference between the back gain (back lobe) and the gain by cross polarization characteristic of the 1st and the 2nd phased-array antennas. This level is very low and is a value which can be ordinarily neglected. After all, the electric wave transmitted from the 1st phased-array antenna is reflected on the target and made incident on the 2nd phased-array antenna so as not to cause mutual intervention.

Abstract: PURPOSE:To improve controllability and operation stability by providing a light deflection control circuit and a light intensity control circuit which give indication values for the modulation and deflection of laser light correcting values for compensating deviations accompanying the modulation and deflection. CONSTITUTION:A laser light irradiation position information signal P from a position measuring instrument 12 is sent to a light deflection control circuit 9 and an arithmetic processing part 10 finds the position of a laser spot S on the surface of a wafer 5.

A beam from the deflector 4 is branched by a beam splitter 11b and a photoelectric converting element 13 detects the quantity of the light and sends its signal (i) to a light modulation control circuit 8. The light intensity distribution of the entire area is measured and light intensity deviations at respective points are computed to find the correcting value, which is sent to an optical modulator 3.

Title: Exposing unit for charged particle beam
Inventor: OKINO TERUAKI
IPC: H01L21/027
Filed: 1982-03-12
Abstract: PURPOSE:To improve precision in a picture drawing process by a method wherein the deviation of a beam axis in a direction vertical to the plane of reference is determined on the basis of the difference between a mark-to-mark distance and a reference value and the results thus obtained are used to control a deflector that in turn regulates the beam position on the material. CONSTITUTION:To determine the deviation of a beam axis prior to pattern drawing, a deflector 6 performs a digital scanning, by using the center of deflection of the beam, of each mark on a reference board 1X (or 1Y) positioned on a side of the unit. Electrons reflected by the marks are detected by a detector 10 and then sent to an arithmetic circuit 12 via a wave-form restoring circuit 11, for the determination of mark positions. When the distance between marks M1 and M2 is L and the reference board 1X is inclined by an angle theta, the beam axis is deviated by an angle alpha when it illuminates the mark M2 displaced by a distance of Lcostheta. The data thus obtained are processed in a CPU5 which determines the deviation alpha in the direction X. Deviation beta that is a vertical or Y-direction deviation is also determined in the same way.

Title: Image measuring apparatus
Inventor: SUGIYAMA HARUO
IPC: G01B11/24
Filed: 1986-02-26
Abstract: PURPOSE:To enable accurate measurement of a specimen even if an optical reflection property of which is high, by irradiating the specimen by a plurality of irradiating beams provided with different wave-length ranges and by developing an irradiated image created by this by the same wave-length range. CONSTITUTION:Beams of light are irradiated onto a specimen A from sources B, C. Among the beam, a beam on the shorter wave-length side reaches the specimen A after passing through a color-filter FB and reaches a camera D after passing through a color-filter FB set in front of the TV camera D and a shadow corresponding to the specimen A is developed as the image. Similarly, a beam from the source C is brought to image development by a TV camera E, after passing of a beam on the longer wave-length through 2 color-filters FR. And, a beam irradiated from the source B and irradiating onto the specimen A and reflected to the direction of the camera E is not available for passing through the color-filter FR, because of its content of shorter wave-length. Accordingly, development of image on the camera E does not take place. In the same way, a reflected beam from the source C does not lend itself to be developed as an image in the camera D. Thus, the irradiated image can be processed electrically for obtaining the required calculational result.
