Title: Image forming device
Inventor: HITAI HIDEO
IPC: H04N1/04
Filed: 1992-05-22
Abstract: PURPOSE:To eliminate image distortion by uniforming the relative speed of the laser beam in the main scanning direction of a photosensitive drum or pixel dot intervals by correcting a picture element clock frequency according to the position in the main scanning direction of the photosensitive drum at the time of radiating the laser beam to the photosensitive drum. CONSTITUTION:Ordinate of figure shows the frequency dividing ratio of picture element clocks and the abscissa shows the dot number in the main scanning direction. In short, the dot number in the abscissa corresponds to the position of the photosensitive drum, whose center is located at the center of the photosensitive drum and whose both edges correspond to the both edges of the photosensitive drum. When a laser irradiation dot speed or the picture element dot clock frequency is made uniform, the scanning speed becomes slower as it goes to the both edges compared with the center. The picture element dot intervals become uneven at the center and at both edges, causing the image distortion. Thus, as shown in the illustration, the correction for gradually increasing the picture element clock frequency as it goes from the center to both edges in the photosensitive drum is performed.

Filed: 1978-12-19
Abstract: PURPOSE: To obtain printing of two colors with a simple apparatus by forming the first and second charge latent images as the charge latent image of a potential larger than a reference voltage with a certain voltage as the reference voltage and the charge latent image of a potential smaller than this and using toners of two colors of charges of mutually different polarities and different colors for these.  
     CONSTITUTION: The first original picture image is the positive image such as the one where the quantity of light corresponding to the portions where toner is to deposit decreases (or not exposed) and the second original picture image is a negative image. These two images will not mutually overlap at the portions where the toner images are to be formed. The potential of the first image recording part is nearly equal to the initial charge voltage V 0 . The quantity of light of the background part of the first image is so applied as to become the surface potential of the value Vb about 1/2 the voltage V 0 . In the exposure of the second image, the quantity of light at which the potential of the image recording part becomes close to the residual potential VR of the photoconductor is applied. In this way, printing of two colors may be accomplished with the simple apparatus.

Title: Mesa type high withstand voltage semiconductor device
Inventor: UCHIDA HIDEAKI
IPC: H01L29/864
Filed: 1980-11-06
Abstract: PURPOSE:To obtain a stable high withstand voltage semiconductor device by absorbing the irregularity of side etching of a mesa groove by the formation of a flat region of the second diffused layer. CONSTITUTION:A P type selectively diffused layer 12 is formed in an N type semiconductor substrate. Then, the second P type diffused layer 13 shallower than the depth of the layer 12 is formed at the outer periphery of the layer 12. Then, a mesa groove 14 is formed to cross the layer 13. Thus, a flat region 13a is formed in the vicinity of the end of the P-N junction. With this configuration, the cylindrical part of the layer 12 in lengthwise direction and the part C surrounded by the curved corner 12a of the bottom, P type diffused layer 13a and mesa groove 14 become locally positive bevel shape of the P-N junction 15. When reverse voltage is applied to the junction 15, a depletion layer expands in response to the shape of the part C due to the existence of the part C, thereby weakening the electric field intensity on the surface of the mesa groove, with the result that a breakdown voltage is increased.
