IPC: G03F7/20
Filed: 1982-12-20
Abstract: PURPOSE:To enable to obtain sufficient pattern accuracy necessary in simple steps by correcting the proximity effect as one pattern a nonrectangular pattern. CONSTITUTION:An L-shaped pattern A to be an object is divided into rectangular and nonrectangular patterns, and the divided patterns are respectively represented by A1-A3. Sampling points become midpoints of the respective sides in the rectangular patterns A1-A3, and become midpoints 2 of oblique sides in the nonrectangular pattern A2. The sampling points also become midpoints of the sides in adjacent patterns B. Then, the intensity of the scattered electron beam at the sampling points is calculated. Then, the correcting amounts of the size of the sides of the pattern A2 and correcting illumination amount are obtained on the basis of the intensity of the calculated scattered electron beam. Subsequently, electron beam exposure is then executed on the basis of the size correcting amount and the correcting illumination amount calculated for the respective patterns A1-A3. According to this method, it is not necessary to divide the nonrectangular pattern into many ultrafine rectangles, but the calculation of the correction can be performed as one pattern.

Title: Message restoring system
Inventor: KASAI KATSUHIRO
IPC: H04L13/00
Filed: 1987-09-09
Abstract: PURPOSE:To detect the non-arrival of intermediate data by subtracting the data lengths of data units that subsequently arrive from a message length before dividing, and deciding whether the value finally goes to zero. CONSTITUTION:Since a header length 4-1, a segment length 4-2, a total length 4-3 are recorded in the leading parts of respective divided data units, the message length before dividing can be obtained by subtracting the header length from the total length. Also, respective data lengths can be obtained by subtracting the header length from the segment length. Accordingly, when the data transmission is normal, the sum value of the data lengths of all the received data units coincides with the message length before dividing. Inversely, by subtracting the data lengths of the received data successively from the message length before dividing, a value zero can be obtained. Therefore, at the time of receiving the final data unit, when the sum-result of data lengths or the subtraction-result does not give a value zero, it can be decided that some intermediate data is missing.

Title: Digital chrominance signal processor
Inventor: FUJII KUNIHIKO
IPC: H04N9/808
Filed: 1986-09-22
Abstract: PURPOSE:To record and reproduce signals with difference carrier chrominance signal frequencies without requiring a switching route by temporarily frequency-converting chrominance signal into a quater of a sampling frequency (fs), that is, 1/4 fs. CONSTITUTION:As for a recording system, an input composite video signal is transmitted in such a way that a luminance signal and chrominance signal are frequency- multiplexed as shown by figure (a). The chrominance signal is two-phase modulated orthogonally by a chrominance carrier frequency fsc. As shown by figure (b), a frequency conversion circuit 11 frequency-converts the chrominance signal by carrier frequency denoted by fc=fsc+1/4 fs. As shown by figure (c), a band-pass filter 12 has such a characteristic that the frequency of 1/4 fs goes to a peak. When an output whose frequency is converted at a previous stage is inputted to the filter, the most of the luminance signal and the sum of the chrominance signals generated by the frequency conversion, are removed, and chrominance signal extending with 1/4 fs as a center can be obtained, as shown by figure (d). A demodulator circuit 13 drops a clock frequency by sampling as shown by figure (e), and demodulates the chrominance components with a frequency of 1/4 fs to two color difference signals.

Filed: 1990-08-29
Abstract: PURPOSE:To transmit a mix mode original to a teletex terminal by converting the mix mode original to a teletex original, and transmitting the teletex original to the teletex terminal using a communication protocol of a teletex. CONSTITUTION:When a main control part 5 detects through an other transmission detecting part 13 that the other transmission is the teletex, the main control part 5 switches the communication protocol to a teletex communication by a switching part 14. And the raster information of a mix mode raster information block is erased by a raster information erasing part 16 of a teletex communication control part 15. Furthermore, by a teletex original converting part 17, only the character information block of the mix mode is combined and converted into the teletex original. Thus, it is possible to transmit the mix mode original to the teletex terminal.
