摘要:
A thermal transfer printer including a thermal head for generating heat in accordance with a desired print pattern, a platen having a surface for supporting an ink-sheet and paper, the ink-sheet and paper being pressed by the thermal head on the platen surface so that ink from the ink-sheet is transferred to the paper, a paper supply for storing and supplying paper, an ink-sheet supply and drive for storing and supplying an ink-sheet, the ink-sheet supply and drive driving the ink-sheet to move in accordance with the movement of the paper, a paper drive arranged between the platen and the paper supply, the paper drive driving the paper by the required length according to the position of the paper relative to the position of the platen, and a paper tension device for applying suitable tension to the paper at least between the platen and the paper drive so that the length by which the paper drive drives the paper is identical with the length by which the paper moves on the platen. Since the length by which the paper moves on the platen corresponds only to the length by which the paper drive drives the paper, the length by which the paper moves on the platen can be correctly controlled through the paper drive.

Cephalosporin compounds having 2-(2-aminothiazol-4-yl)-2{(1S)-carboxyethoxyimino}acetyl group on the side chain at the 7-position thereof and 1-ethylpyridinium-4-ylthiomethyl group on the side chain at the 3-position thereof or non-toxic salts thereof are excellent antibacterial agents for mammals including human. The cephalosporin derivatives have low toxicity.
摘要:
A rotor of a built-in motor includes a shaft having a stepped part and a sleeve having a hollow space arranged to cover the stepped part of the shaft and a hydraulic pressure supply means. The sleeve is fitted with the shaft at the stepped part. A core is fitted with the sleeve. Hydraulic pressure applied to the hollow space within the sleeve via the hydraulic pressure supply means loosens the fit between the sleeve and the shaft, thereby allowing the shaft to be readily removed from the sleeve and core portion.
摘要:
A semiconductor integrated logic circuit comprises a load transistor having a carrier injecting region and a carrier extracting region and an inverter transistor having a source region, drain regions, channel regions each connected between the source region and each of the drain regions, and gate regions defining the respective channel regions therebetween. The extracting region is merged into the gate regions. The channel regions have such dimensions and an impurity concentration that the channels are closed with depletion layers extending from the gate regions at zero gate voltage. The gate regions constitute a logic input and the drains constitute logic outputs. The zero gate voltage renders the channels non-conductive and the raised voltage renders the channels conductive, thus realizing an inverter circuit useful for wired logics.
