    摘要: The plastic lens of the present invention consists of a copolymer obtained by copolymerizing a monomer mixture consisting of given proportions of diethylene glycol bis(allyl carbonate), benzyl methacrylate, diallyl phthalate (these three monomers has been used as a monomer mixture for conventional plastic lenses) and, as an additional monomer, an alkyl methacrylate. This copolymer has excellent adhesion to upper and lower molds and, when immersed in, for example, a cleaning solution such as a methylene chloride-strong alkali mixed cleaning solution or the like, causes no separation from the molds; accordingly in the copolymer, there can be prevented the occurrence of surface roughening, cloudiness and striae which have been problems in conventional plastic lenses.

    摘要: A printer includes improved paper feeding mechanism. A manual paper guide plate below an automatic paper feeding device can guide a thick piece of paper into a printing position on the platen without bending it hard around the platen. A pin tractor below the manual paper guide plate can feed a continuous web substantially straight into the printing position. A print head below the platen prints out on the lower surface of printing paper, whereby the printed individual cut sheets of paper being piled up one after another with the printed surface facing downward in a proper page order. A paper tray for holding the printed paper can alternatively change its position to reverse the discharge direction of the printed continuous web. The printed and reversed paper can be stacked on the upper surface of the manual paper guide plate.

    摘要: A pre-drive circuit performs on/off control of a switching transistor element (Q.sub.1) through a pulse transformer (T) having two primary windings (P.sub.1, P.sub.2). Switching elements (Q.sub.2, Q.sub.3) are respectively connected to the primary windings. Feedback circuits (D.sub.1, D.sub.2) connect signal output terminals of the respective switching elements (Q.sub.2, Q.sub.3) to control terminals of the opposite switching elements (Q.sub.3, Q.sub.2).

    摘要: A power source for control equipment which is designed so that even if one or more independent power sources (700) are added to a main power source (600), the power source arrangement, as viewed from the control equipment supplied with power therefrom, can always be regarded as if one power source were connected thereto. The operative state of control circuit power sources (601, 701) provided in the main power source (600) and the additional power source (700) is detected by control circuit power source abnormality detecting circuits (603, 703), and the operative state of driving power sources (602, 702) provided in the main power source (600) and the additional power source (700) is detected by driving power source abnormality detecting circuits (604, 704). All the driving power sources (602, 702) are turned ON substantially concurrently after the outputs from all the control circuit power sources (601, 701) have reached their normal state, and they are turned OFF substantially concurrently when the output from any one of the control circuit power sources (601, 701) has become abnormal. An enable signal (EN), which is sent to the control equipment, is turned ON after all the control circuit power sources (601, 701) and driving power sources (602, 702) have reached their normal operative state, and is turned OFF when an abnormality has occurred in any one of the power sources.
