IPC: G06F9/46
Filed: 1986-08-29
Abstract: PURPOSE:To neglet processing time compared with keying time in terms of alphanumeric by changing the flow of data with Japanese word processing start/end instruction and minimizing overheads of an OS down to several steps against the alphanumerics. CONSTITUTION:When a Japanese word processing start key is pushed, an interruption 105 is applied to a KANA (Japanese syllabary)/KANJI (Chinese characters) conversion program 106 via an interruption process 104 of a kernel 103. The program 106 produces a system call 107 to the kernel 103 and switches the input routes. The increase of overheads can be reduced down to just several steps against the alphameric and therefore ignored against the keying time. The data inputted to the program 106 are converted into KANJI and delivered to a suer program 101 and at the same time displayed on a CRT 108. When the KANJI input processing is through and then a Japanese work processing end key is pushed, the call 107 is produced via the process 104, etc., and the flow of data is switched to an alphanumeric input process 109.

CONSTITUTION:An un-enlarged tube 13a is ushered to a diametrally enlarging part 8 so as to be successively taken up through a leading-in port 11 out of a take-up port 10. Vacuumizing means 16 and 17 are run within the route lying between the leading-in port to the take-up port. As a result, the un-enlarged tube 13a is enlarged and comes into contact internally with a cooling sizing part 12 so as to be cooled down in order to be taken up in the form of an enlarged tube 13. Because the enlarged tube 13 comes into contact internally with the cooling sizing part 12, the interior of a casing 9 is divided by the sizing part 12 into a first vacuum chamber 14 before the sizing part 12 and a second vacuum chamber 15 after the sizing part 12 and consequently the control of the vacuum pressures in the vacuum chambers are independently possible and the operating condition in the part 8 is stabilized.
