Abstract:
A color copying machine contains a scanning unit driven by a motor for applying a color scanning beam onto a manuscript, a photoconductive drum operable to rotate for being exposed to the scanning beam to form on a peripheral surface thereof a latent image of the manuscript. The color copying machine further contains a device for applying a toner to the latent image to form a toner image, and a transfer drum for holding a record sheet onto which the toner image on the photoconductive drum is transferred. A main controller calculates data representative of a speed of the motor in accordance with a magnification rate of the copy image to be formed on the record sheet to the image on the manuscript, and outputs a pulse signal whose pulse rate is proportional to the calculated speed data. The main controller outputs the pulse signal to a controller which drives the motor at a speed determined by the pulse rate of the pulse signal. Thus, the speed of the scanning unit is determined in accordance with the magnification rate.

Abstract:
A wet paper web transfer belt (1) has a wet paper web-side layer (31), including a hydrophilic fibrous body (30), and a machine-side layer (32). A base fabric (33) disposed in the belt comprises a first woven fabric (34), disposed on a wet paper web (W) side, and a second woven fabric (35) disposed on a press roll (10) side, and the first woven fabric (34) and the second woven fabric (35) are stacked together. A portion of the hydrophilic fibrous body (30) is exposed on a surface (37) of the wet paper web-side layer (31). The first woven fabric (34) and the second woven fabric (35) include weft yarns (36) made of a material of low water absorptivity. When the hydrophilic fibrous body (30) is formed in the wet paper web-side layer (31) of the belt (1) by needle punching, an increase in the widthwise dimension of the belt due to the absorption of water by the hydrophilic fibrous body (30) is reduced.
Abstract:
A wet paper web transfer belt comprises a base body 30, a paper side layer 20, and a machine side layer 23. The paper side layer 20 is composed of a paper contacting side batt layer 21 made of hydrophilic fibers 41 and a base bode side batt layer 22 without the hydrophilic fibers 41, at least the paper contacting side batt layer 21 being impregnated with a high molecular weight elastic body 50 and at least a part of the hydrophilic fibers 41 being exposed on the surface of the paper contacting side batt layer 21. The water contained in the wet paper web remains within the paper contacting side batt layer 21 made of the hydrophilic fibers 41 with only a small amount of water moving into the base body side batt layer 22, thereby reducing dimensional changes of the belt. Further, since the water contained in the wet paper web remains within the hydrophilic fibers 41 exposed on the surface of the paper side layer 20, the belt is capable of transferring the wet paper web attached thereon while allowing smooth detachment when transferring it to the next process.
Abstract:
An image display system in which an image output equipment and an image control apparatus are connected by a moving image digital interface such as HDMI, executes a battery saving in the image output equipment in case of a still image display. The image display system discriminates whether an image, input by an externally-connected digital image output apparatus is a still image, and stores the input image in a frame memory. In case of a discrimination as a still image, the discrimination as a still image is informed to the digital image output apparatus, and the image read out from the frame memory is used for display on a connected display apparatus.
Abstract:
A touch panel includes a first substrate, a second substrate, a slit, and a groove. The first substrate has a first conductive layer, and a plurality of first electrodes that extend from both ends of the first conductive layer and that have first electrode lead sections. The second substrate has a second conductive layer, and a plurality of second electrodes that extend form both ends of the second conductive layer and that have second electrode lead sections. The slit is provided in the first conductive layer and the second conductive layer and has an intersection or a terminal section. The groove section is provided to surround the intersection or the terminal section. This structure provides the touch panel that can have stable electrical connection and separation by a simple structure.

The present invention is to provide a production technology by which an optically active 2-[6-(hydroxymethyl)-1,3-dioxan-4-yl]acetic acid derivative, which are of value as pharmaceutical intermediates, can be produced from inexpensive and readily available starting materials without using any extraordinary equipment such as an ultra-low-temperature reactor. The present invention is a production process of an optically active 2-[6-(hydroxymethyl)-1,3-dioxan-4-yl]acetic acid derivative which comprises reacting an enolate, prepared by permitting a base or a 0-valent metal to act on an acetic acid ester derivative with (S)-β-hydroxy-γ-butyrolactone at a temperature not lower than −30° C. to give a dihydroxyoxohexanoic acid derivative, treating the same with an acylating agent in the presence of a base to produce a dihydroxyoxohexanoic acid monoacyl derivative, reducing this compound with a microorganism to produce a trihydroxyhexanoic acid monoacyl derivative, treating this compound with an acetal-forming reagent in the presence of an acid catalyst to produce an acyloxy-methyldioxanylacetic acid derivative, and finally, subjecting this compound to solvolysis in the presence of a base.
