A double-side coating apparatus (1) includes a holding mechanism (3a) which holds a substrate (2) to be processed so that the thickness direction of the substrate (2) to be processed is a horizontal direction; a rotational driving mechanism which rotates the substrate (2) to be processed in a circumferential direction; a first coating solution nozzle (18a) which jets a coating solution onto one main surface (2a) of the substrate (2) to be processed; and a second coating solution nozzle which jets the coating solution onto the other main surface (2b) of the substrate (2) to be processed. The first coating solution nozzle (18a) and the second coating solution nozzle are symmetrically arranged with respect to a thickness center surface of the substrate (2) to be processed. Provided is an edge rinsing apparatus which can accurately and stably rinse only a fixed width of an outer peripheral portion of the substrate and can easily control the width of the outer peripheral portion to be rinsed even if the width of the outer peripheral portion to be rinsed is small.

摘要： In a sheet stacking apparatus, a pair of side members includes a pair of lower side members which is provided with an approximately same distance therebetween as a width of a planographic printing plate and limits a movement in the planographic printing plate width direction; and a pair of upper side members which are provided above the pair of lower side members, each of which is provided with a movable section movable in the planographic printing plate width direction, and on which tapered surfaces are formed facing each other in a generally V shape. The distance between the pair of upper side members is controlled by driving the movable sections of the pair of upper side members so as to prevent quality degradation caused by a thrown-in sheet scratching a stacked sheet.

摘要： A display control circuit incorporating a RAM in which display data is stored, comprises an oscillation circuit which oscillates a reference clock to define a transfer period in which the display data is transferred from the RAM to a display and a counter circuit which counts the number of the reference clocks, and the transfer period is determined by the number of counts of the reference clocks by the counter circuit. In addition, the oscillation circuit starts oscillation when a transfer request of the display data is generated while the oscillation is stopped, and stops the oscillation when an access request from the CPU is generated during the oscillation, and resumes the oscillation when the access request is stopped.
