Title: Current mirror circuit and photoelectric transducer
Inventor: KOZUKA HIRAKI
IPC: H04N5/374
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To make actualizable a circuit which operates normally when powered on even at the time of light irradiation by making a photocurrent generated in a drain area more in a PMOS transistor than in an NMOS transistor, in a photoelectric transducer having a current mirror circuit. SOLUTION: In the current mirror constant current circuit 20 connected to the gates of PMOS transistors 13, 13', and 13" as constant-current loads, the drain area of a 1st PMOS transistor 2 is larger than that of a 1st NMOS transistor 4. Therefore, a light-generated hole generated in the drain area of the 1st PMOS transistor 2 is larger than a light-generated electron generated in the drain area of the 1st NMOS transistor 4 and the gate potentials of NMOS transistors 3 and 4 rise, so that the current mirror constant-current circuit 20 operates normally.  The constant-current circuit 20 is not limited to a current mirror circuit and even when it is a circuit such as a differential amplifier circuit, malfunction under the influence of light irradiation can be prevented on condition that an element canceling the electron and positive hole of a light carrier generated at the PN junction part is available.

IPC: G06V10/36
Filed: 1990-10-08
Abstract: PURPOSE: To execute convolution calculation and to correct a two-dimensional array only by once making a kernel size smaller than the size of a processing element array to pass through by restricting the size of an external memory and the size of an accumulator bus. CONSTITUTION: Eight bit picture element data 20 flows into a register 11 from the register of a previous element.

Numeric values in the registers 11 and 13 are multiplied in a multiplier 15 and the calculated result of 16 bits is accumulated in an accumulator 17. The kernel size of convolution decides time when the numeric value of an accumulator register is placed on a 28 pin output bus 19. A ninth control bit 14 is added to a data route and kernel weight synchronizes the start and the end of a kernel. The numeric value is placed on 28 bit ASAOUT 1 by using a control bit and the next accumulator is started.

Title: Image forming device
Inventor: SASAME HIROSHI
IPC: G03G15/08
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device which is excellent in reliability and which is constituted so that a high-definition image is formed immediately after setting a condition using an image for detecting density in which the consumed quantity of toner is suppressed by forming at least one image for detecting density out of the plural images for detecting density in the whole image forming feasible area of an image carrier in the longitudinal direction. SOLUTION: The yellow image for detecting density is formed on a photosensitive drum. At this time, developing bias is varied to -500 V from -200 V with the step of 50 V. When the developing bias is -450 V and -500 V, the image forming area of the image for detecting density is not only the area read by a density sensor but the image for detecting density is widely formed extending over the whole image forming feasible area of the photosensitive drum in the longitudinal direction. Thus, since the toner holding quantity of a developing sleeve in the longitudinal direction is prevented from becoming remarkably different, the quantity of the toner consumed by the image for detecting density used for controlling the image forming conditions is suppressed and a ghost is prevented from occurring.

IPC: H04N5/208
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To make an edge part steep by preventing insufficient edge emphasis and occurrence of ringing caused in the vicinity of the edge. SOLUTION: Class separation relating to an edge structure is applied to edge signals extracted from signals resulting from applying wavelet transformation to a received image signal. A high frequency component signal is added to an edge part depending on a class to which the edge part of the image signal receiving wavelet conversion belongs by referencing a class information table (class rule table) where cross reference between each class and each high frequency component signal to be added to the edge part of the image signal that is wavelet-transformed is decided in advance, and the resulting edge receives inverse wavelet transformation and the result is used for contour emphasis.

Abstract: PROBLEM TO BE SOLVED: To additionallly install plural cold cathode tubes without increasing the thickness of a light transmission plate so much by making the end face of the light transmission plate an inclined surface and juxtaposing plural cold cathode tubes on the inclined surface. SOLUTION: One end face 11 of the light transmission plate 1 is formed to be such an inclined surface 7 that a back surface 12 is positioned on the outside, and three cold cathode tubes 21, 22 and 23 of RGB, for example, are additionally installed to be juxtaposed on the inclined surface 7. The inclined surface 7 is processed to such an extent that optical turbulence is not caused, and a desirable angle is selected in accordance with the thickness of the plate 1 as the inclination angle of the surface 7. The inclination angle is different among respective members to be used; for example, it is desirable that the angle is set to about 18 deg. in the case the thickness of the plate 1 is 3mm and set near 30 deg. in the case the thickness of the plate 1 is 5mm, because the high luminance of the backlight for a liquid crystal display is obtained at such angles.
