Title: Copying method for multiple sheets
Inventor: SATOU TSUTOMU
IPC: G03G13/00
Filed: 1980-08-27
Abstract: PURPOSE:To perform copying of multiple sheets of good quality with simple processes by performing prescribed corona charging and the like by using a photoreceptor laminated with photoconductive layers, one of which is made conductive by irradiation of specific color and the other has rectifying effect between the same and a conductive base. CONSTITUTION:The 1st photoconductive layer 1B which is laminated on a conductive base 1A of a photoreceptor 1 and has rectifying characteristic with the base 1A is laminated thereon with the 2nd photoconductive layer 1C which is made conductive by the exposure of the specific light which does not conduct the layer 1B. If the photoreceptor 1 is charged to the same polarity as said rectifying characteristic by a charger 2, and is exposed by specific color light LA, the layer 1C is made conductive and the layer 1B is charged. Thence, when it is exposed with images, the surface potential in the area of the photoreceptor 1 opposing to the white part W of an original 0 disappears and the latent image of the black part N is formed by the electric charge distributed in the boundary surface area of the layers 1B, 1C. Hence, no latent image charge leaks and the latent image stabilizes for a long period. Further, if the photoreceptor 1 is bujected to prescribed AC corona charging, the latent image is restored, and the copying of multiple sheets of good quality is accomplished with the simple processes.

Title: Ink jet apparatus
Inventor: YOSHIMURA MANABU
IPC: B41J2/135
Filed: 1995-05-17
Abstract: PURPOSE: To eliminate the unstable injection caused by the stagnation of air bubbles by eliminating the difference in level between a nozzle and an ink chamber. CONSTITUTION: A nozzle plate having the surfaces 85a, 85b corresponding to the first and second ground surfaces 80a, 80b formed by grinding the upper and lower corner surfaces of the end surface of an ink chamber 4 is produced and a nozzle 50 is formed at the position of a surface 82. The nozzle plate is bonded to one end of the ink chamber 4 and a manifold 90 is bonded to the other end of the ink chamber 4 to obtain an ink jet head 100. Since the nozzle 50 and the ink chamber 4 are allowed to smoothly communicate with each other without almost generating difference in level in the head 100, the trapping of air bubbles is eliminated. Therefore, the stop of the injection of ink droplets or the change of the jet speed of ink liquid droplets caused by the presence of air bubbles in the vicinity of the nozzle is prevented and stable injection can be kept.

Title: Diagnostic method for equipment abnormality
Inventor: AIHARA KAZUYUKI
IPC: G01R31/00
Filed: 1989-05-11
Abstract: PURPOSE:To instantaneously diagnose an equipment abnormality by learning the inputted conditions of various equipments with the use of a neural network and discriminating whether the equipment is normal or abnormal basing on the learned result when new conditions of various equipments are inputted. CONSTITUTION:When the cause for abnormality is known, e.g., in a unit 32, the various kinds of measured values at this time are inputted to each unit 11, 12...1l of an input layer 10. When network coupling coefficients between the input layer 10 and an intermediate layer 20, and between the intermediate layer 20 and output layer 30 do not take adequate values at this time, a signal of logic 1 is not always outputted by an output unit 32 and also a signal of logic 0 is not always outputted by the other units. So, the coupling coefficients of networks are changed to learn that the signal of logic 1 is outputted by only the unit 32 of output layer 30 and the signal of logic 0 is outputted by the other units. This procedure is repeated for the other causes for abnormality, then the learning is finished. After that, the existence of equipment abnormality and the cause, if the abnormality is existed, are estimated by means of inputting the various kinds of values newly measured to the units 11, 12...1l of the input layer 10.
