Title: Image processing method of heat-sensitive print
Inventor: ENOMOTO HISASHI
IPC: B41J2/355
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To materialize the sharp edge recording of an image. SOLUTION: When respective pixels 22 are recorded in colors with respective heating elements 21a-21c of a thermal head 15, both bias heating by bias data and gradation heating by gradation data are performed. At the edge portion of an image, at which the gradation data become sharply larger, correction data, which responds to the number of lines X from a head driving position, the number of lines N from an edge and the amount of change in the gradation data at the edge, are obtained and added to the gradation data. Since the heating elements generate heat energies excessively by the amount added by the correction data, the temperature leading edges of the heating elements are improved, resulting in recording the edge of an image in colors with the desired densities.

Title: Image forming device
Inventor: WATANABE YASUNARI
IPC: G03G15/08
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To stably develop, in a short time after a device has started up, and to highly increase a speed by enhancing further slide contact operation by a slide contact means during the preliminary operation of a device main body, as compared to that during its ordinary operation. SOLUTION: A developing sleeve 62 rotates forward with a photoreceptor drum 1, and its surface is moderately rugged for the high establishment of slide friction between toner and itself and for the satisfactory carrying of the toner. In a position higher than it, a developing blade 61 is provided so as to abut on the peripheral face of the developing sleeve 62 in contact along its face. When an image formation signal is transmitted to an image forming device, a preliminary rotation (preliminary operation) for image formation is started. Therefore, by rotating the developing device at higher speed during the preliminary rotation time, a slide contact operation is enhanced to give chances to apply triboelectricity to more toners. It is preferable that the revolving speed of the developing device at this time be 1.2-2 times higher than the speed of that during the normal operation of an image forming device.

Patent JP-H1140808-A (JP)
Title: Semiconductor device and its manufacture
Inventor: HOTTA KOJI
IPC: H01L29/739
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device whose overall thickness size, and the like are not increased, in which the ON-resistance and a leakage current are not increased, and whose transient characteristic is improved when a switch is turned off by a method, wherein between the side of a part of a first conductivity semiconductor region and the side of an opposite part, a part whose impurity concentration is in the middle between those of them is provided. SOLUTION: A drift region 102a in an ON-state is set to a state such that electrons and holes are filled at high concentration. When a switch is turned off, a depletion layer whose carrier concentration is very low is spread from a p-n junction in the interface between a p<+> -body region 109 and a p-body region 107. Even after the turning- off operation of the switch, a collector current continues to flow, while the depletion layer is spread continuously. When the depletion layer is spread so as to reach an inclination distribution region out of the drift region 102a, its spread is suppressed, its spread speed becomes low, and its spread is stopped. Consequently, the collector current is not reduced but reduced gradually.  As a result, even when a semiconductor device is used in a circuit which contains an inductive load, its transient characteristic can be improved in the turning-off operation of the switch, in such a way that the problem of counterelectromotive force is not generated.
