Title: Minidisk controller
Inventor: NISHI KEITA
IPC: G11B27/00
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To increase recording time by correcting the address length of an area to be deleted including an adjacent unused area before the operation of setting the area to be deleted in a recording residual area or the unused area depending on whether the address length of the area to be deleted is longer than a specified value or shorter. SOLUTION: When music is deleted, a control microcomputer 6 reads the conent of a UTOC in a 255 byte memory inside, refers to the disk address of a slot for managing a recording residual area (FRA) and retrieves adjacent unused areas before and after an area to be deleted. When an FRA slot is connected before a deletion slot, the end address of the deletion slot is set to the end address of the FRA slot before it, and thus the area to be deleted is incorporated in the FRA part before it. When the FRA slot is connected to the rear side, the start address of the deletion slot is set to the start address of the rear FRA slot.

Title: Ribbon feed controller
Inventor: NUIDA AKIRA
IPC: B41J33/36
Filed: 1985-12-27
Abstract: PURPOSE:To enable a ribbon to be used more effectively, by a method wherein a ribbon occupation data on a character to be printed this time is collated with that on a character printed at the preceding time, a minimum ribbon feed quantity which ensures that the characters do not overlap on each other on the ribbon is calculated, and the ribbon is fed by such a ribbon feed quantity for each character. CONSTITUTION:Assuming that a character printed at the preceding time is 'P' and a character to be printed this time is 'd', ribbon occupation data on these characters are read from a data table 21, and the AND of these ribbon occupation data is calculated. The AND thus calculated is '00111100'. Therefore, blocks with addresses (1, 3), (1, 4), (2, 1), (2, 2) for the character 'd' are to overlap on those for the character 'P'. The ribbon occupation data on the character printed at the preceding time is shifted by an amount corresponding to one block length Q, and the ribbon is fed by an amount corresponding to the shift quantity. Thereafter, ANDing is again performed. The result of the ANDing is '0', so that no block overlaps in this case.

Title: Printing method and thermal transfer printer
Inventor: UEDA KAZUO
IPC: B41J33/14
Filed: 1988-11-21
Abstract: PURPOSE:To obtain a thermal transfer printer wherein an ink ribbon can be separated from a sheet to be printed, in a heated or cooled state, depending on the kind of said sheet by so arranging that said ink ribbon is started to be wound up after a carriage is moved a predetermined distance after the start of printing, thereby to separate said ink ribbon after an ink melted by the heat of a thermal head is turned solid. CONSTITUTION:When each of protrusions 36, 37 and 32, 33 is in the form of a fan with a center angle 20 deg.C, the protrusions 36, 37 of a take-up gear 34 are meshed with the protrusions 32, 33 of a spacer 28 after the take-up gear 34 is rotated idly 34 deg. at most. The spacer 28 consequently starts rotating. Moreover, a pressure plate 26 is rotated by the friction force with the spacer 28, so that an ink ribbon is started to be wound up via a main shaft 28. Accordingly, although printing by a thermal head 15 is started simultaneously when a carriage 14 is moved, wind-up of the ink ribbon is started when a take-up bobbin 21 is rotated after the carriage 14 is moved a predetermined distance. Therefore, the ink ribbon can be detached after the ink in the melting state is cooled and turned solid.

Abstract: PURPOSE:To obtain a carnitine hydrochloride salt having high optical purity and useful as a remedy for cardiac diseases, hyper-lipemia, venous diseases, etc., in high yield by hydrolyzing a trimethyl-propanamium chloride derivative in the presence of an aqueous solution of hydrochloric acid. CONSTITUTION:The objective carnitine hydrochloride salt can be produced by hydrolyzing 3-methoxycarbonyl-2-hydroxy-N,N,N-trimethyl-1-propanamium chloride with an aqueous solution of hydrochloric acid while successively removing the hydrochloric acid solution containing methanol produced by the hydrolysis reaction. After the completion of the hydrolysis, a solvent such as methyl isobutyl ketone is added to the system and water is removed to deposit crystal of carnitine hydrochloride salt in the solvent. Since the hydrolysis is carried out while successively removing the produced methanol, the amount of the hydrochloric acid solution can be decreased to an extremely low level.
