Title: Power circuit
Inventor: KOKUBO KENICHI
IPC: G05F3/26
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent an undesired current from flowing when a standby switch is OFF by providing a 2nd transistor(TR) which has a base where a 2nd power line is connected and a collector where a 1st power line is connected. SOLUTION: A transistor Tr2 has its emitter grounded and is applied with a source voltage Vcc2 at its base, so the transistor Tr2 turns ON. When the standby switch is turned off and the source voltage Vcc1 is stopped from being supplied, the base of a transistor Tr1 is virtually grounded. Then the base- emitter voltage of the Tr1 drops below 0.7 V, so the Tr1 turns OFF. Consequently, the collector of the Tr1 is placed in a high-impedance state, so current mirror circuits IM1 and IM2 are unable to operate and bias generation is completely stopped. When the Tr1 turns OFF, the current path is completely cut off and no leak current is generated.

Abstract: PROBLEM TO BE SOLVED: To realize a gradation printing with high image quality by an arrangement wherein a plurality of ink droplet jet ports have different distance to a recording medium and an ink droplet having a large diameter is jetted from an ink jet port having a long distance to the recording medium. SOLUTION: A plurality of nozzles 22 are arranged in two parallel rows, i.e., a row of large diameter nozzles 22 jetting a large diameter ink droplet and a row of small diameter nozzles 22b jetting a small diameter ink droplet. Since contamination in the vicinity of the opening of a nozzle 22 has a significant effect when the speed of ink droplet is low, the lowest speed is set at 1.5m/sec or above and the highest speed is set at 15m/sec or below. Trajection accuracy of the ink droplet is enhanced as the distance between the nozzle 22 and a recording medium is decreased and the distance is preferably set in the range of 0.5-1.5mm while taking account of various types of sheet.

CONSTITUTION:An UP 3 decides a partial page, having the partial page name 2b of a page printing data 2 of EX2, that it is the lower partial page of covered binding from a page constituting information 1a and a partial page name 1c. Coordinates (x2, y2), showing the letter arranging position of the partial page printing data 2b, are an information showing the arranging position in the lower partial page. Accordingly, the UP 3 constitutes the partial page so that the position (B) of the partial page constituting information 1a comes on a FDM 10 and the lowermost raster of the lower partial page becomes the uppermost raster of the partial page 10b on the FDM 10 and determines a position (b). Letter arrangement address (x2, y2) on the FDM 10 is obtained by adding the position (b) with values obtained by converting coordinates (22, 42) into dot address in the partial page. The letters 1, 2, 3 of the partial page printing data (2b) are deployed in the same manner as an upper partial page.
