Abstract: An image forming apparatus has a normal print mode in which input image data for a plurality of pages are processed into images on the same number of pages of paper, and a trial print mode in which the input image data are processed into minified images on fewer pages of the paper for trial output such that a user can check an output result to be obtained in the normal mode beforehand. In the trial print mode, a blank page detector detects a blank page from the input image data, and an image data minifier converts the image data stored in an image data buffer into minified image data and stores the data in a second buffer. Then, a plotting section develops the minified image data read from the second data buffer into a plotting pattern, which is then written to a page buffer. In an output section, the plotting pattern read from the page buffer is processed into a visible image. At this time, an image corresponding to the blank page detected by the blank page detector is not formed.

Accordingly, current flowing though adjacent extended electrodes is of substantially equal intensity but different in direction. As a result, inductance produced effectively cancels out that of adjacent extended electrodes.

Abstract: A plasma processing apparatus that allows processing of high quality under a wider processing condition is provided by optimizing the distance between a plasma region and a substrate even in the case where the processing condition such as process pressure or high frequency output differs. A plasma chamber is divided into a lower plasma chamber and an upper plasma chamber. A process chamber and the lower plasma chamber are connected flexibly by a lower chamber bellows. The lower plasma chamber and the upper plasma chamber are connected flexibly by an upper chamber bellows. Since the radioactive species volume is increased when the process pressure is low, the lower and upper plasma chambers are respectively raised. In contrast, since the radioactive species volume is reduced when the process pressure is high, the upper and lower plasma chambers are respectively lowered.

Abstract: When a user places his finger on a fingerprint detecting section, in the fingerprint detecting section, a shadow made by the finger placed on the fingerprint detecting section is detected by a sensor portion, and then, when it is judged that a shape of the detected shadow coincides with a distribution of the shadow made by the user's finger, and thereby, a power is turned on. Thereafter, a fingerprint is detected from the finger placed on the fingerprint detecting section, and then, the detected fingerprint is collated with a previously stored fingerprint data so as to identify the user. Further, it is possible to use various data such as schedule data corresponding to the identified user. Therefore, this dispenses an operation for turning on the power and an instruction for starting fingerprint collation.
