摘要:
An image forming apparatus includes an image forming section, a heat source, a fixing rotating body, a pressurizing rotating body, a feeding section for feeding a medium, a temperature adjusting section for controlling an amount of heat generated by the heat source, and a control section. The control section switches between a first mode in which the fixing rotating body and the pressurizing rotating body rotate at a first circumferential speed and the medium is fed to the image forming section at a first distance interval, and a second mode in which the fixing rotating body and the pressurizing rotating body rotate at a second circumferential speed higher than the first circumferential speed and the medium is fed to the image forming section at a second distance interval longer than the first distance interval.

Provided is a production method of glycolic acid having a first step of preparing glycolonitrile from formaldehyde and hydrocyanic acid and a second step of hydrolyzing the glycolonitrile into glycolic acid directly or via a glycolate salt, which method can produce glycolic acid in easy production and purification steps while consuming less energy. In the production method, by carrying out the first and second steps continuously or by storing the glycolonitrile obtained in the first step at pH 4 or less and carrying out a hydrolysis reaction of the second step at from pH 5 to 9, a production yield of glycolic acid, activity for the production of glycolic acid and accumulated concentration of glycolic acid are improved, resulting in the production of glycolic acid having an improved purity and quality.
摘要:
An example control signal generating circuit CTL for controlling the writing into pixels PIX instructs a data signal line drive circuit SD2, which is for driving pixels in a non-display area, to write a voltage VB or a voltage VW which are for non-displaying, not only in the first frame but also once in a predetermined number of frames. In other words, the pixels in the display area are refreshed at intervals longer than those in the case of refreshing the pixels in each frame. Thus, even if the mobility of an active element is high and the leak current on the occasion of OFF-state is large, or even if a large amount of electric charge is accumulated because of the photoelectric effect due to the use of a backlight, it is possible to prevent unnecessary displaying on the display area, which is caused because the writing into the pixels in the display area influences on the pixels in the non-display area, and hence it is possible to improve the quality of partial displaying, while restraining the power consumption.

摘要:
A display system includes a combination image dividing section arranged to divide a single combination image composed of a plurality of item images into a plurality of image blocks such that each of the image blocks has an item image; an image inputting controlling section arranged to lay out the individual image blocks; and an image inputting controlling section arranged to generate display data based on the image blocks laid out thereby. This can achieve a display system, to be mounted in the maneuverable moving object and having high degrees of freedom for screen layout, at a lower cost.
摘要:
An input signal INDATA inputted to a sender-side interface portion is encoded by an encoder, and a transmission signal generated by the encoding is transmitted to a receiver-side interface portion through two signal transmission lines. The input signal INDATA is encoded in such a manner that the logic level of the transmission signal transmitted through at least one of the two signal transmission lines is changed in any two consecutive elementary periods. The receiver-side interface portion is provided with a clock receiver, and a clock signal is generated based on the change of the transmission signals supplied from the two signal transmission lines.
摘要:
A method for producing aliphatic O-arylurethanes by the reaction of an aliphatic primary amine with an aromatic hydroxyl compound and urea. Ammonia produced as a by-product in the reaction is removed during the reaction so that the ammonia concentration of the reaction solution is maintained at 2 wt % or less.
摘要:
A fixing device for performing a thermal fixing for fixing an unfixed image onto a recording sheet by passing the recording sheet through a fixing nip formed by a fixing rotator and a pressing member pressing the fixing rotator. The fixing device obtains a value indicating an amount of paper dust attached to the fixing rotator, and when the amount of paper dust indicated by the obtained value is equal to or larger than a permissible amount, performs a control so that a larger amount of heat is supplied to the recording sheet in the thermal fixing than when the amount of paper dust indicated by the obtained value is smaller than the permissible amount.
