Patent JP-H0740571-A (JP)
Title: Thermal head
Inventor: MORI YUICHIRO
IPC: B41J2/36
Filed: 1993-07-27
Abstract: PURPOSE:To prevent irregular density which occurs when printing speed is accelerated and halftone printing is performed, by providing a means for supplying a drive signal of a heating element string A, which directly contributes to recording, to a heating element string B which does not contribute to recording via an inverting circuit, and a means for controlling drives of corresponding elements in the element strings A and B reversely to each other. CONSTITUTION:A heating element string b25 is provided corresponding to a heating element string a24 which actually contributes to recording (printing). The string a24 comprises n heating elements 2a1-2an. Likewise, the string b25 also comprises n heating elements 2b1-2bn. The strings a and b are arranged at relative positions on a front and a rear of a ceramic plate. When the string a is not heated, the string b is controlled to heat. Accordingly, the total number of energizing elements in the strings a and b is always n whatever a print pattern is, and the overall width of the element strings is heated always uniformly. Therefore, when a power source which changes voltage based on the contents programmed previously is used, density of print can be controlled to be constant.

Filed: 1989-07-19
Abstract: PURPOSE:To shorten time required for a restoration processing at the time of a fault in a data base by extracting data base update journal from a journal file and sorting them in the order of physical addresses on the storage medium of the data base. CONSTITUTION:It is assumed that the fault occurs in an area B20-B after the processing of a transaction 3(200-3). At that time, the data base update journal on the area B20-B is integrated and sorted so as to generate an integration journal file 50. Namely, the data base update journals on the area B are extracted from respective magnetic tapes 30-a and 30-b and are sorted in the order of the physical addresses on the storage medium storing the area B of data to be updated. The order of the physical addresses of update data in the area B is b1, b3 and b2 and the update journals as against them are sorted in the order. Then, the content of a backup file B40-B in the area B is copied in a standby volume 70 at the time of the fault in the data base. Then, the area B is restored on the volume 70 at last.
