Abstract: In conventional color digital copy machines, when copying in color mode, the polygon mirror of the laser beam scanner for black, which is driven at a higher speed than those of the other colors, is switched to a slower speed in conformity with the speed of the polygon mirrors for the other colors. However, a drawback of this structure is that, especially when switching from monochrome to color mode, the time required to obtain the first copy is lengthened, and the operating efficiency of copying is poor. In the present invention, when copying in color mode, the rotation speed of the polygon mirror of the laser scanner unit for black is not changed at all, but, by skipping certain mirror surfaces of the polygon mirror, and/or by skipping certain of a plurality of laser light sources, the scanning density of the laser scanner unit for black can be brought into conformity with that of the laser scanner units for the other colors.

As a result, a liquid crystal display device having an excellent displaying quality is provided in which a cell gap is uniform, no contamination and impairment of an alignment film occur, and alignment nonuniformity by rubbing is not generated, even when a screen is made larger.

Abstract: In an image forming system, a digital copying machine, which is requested to determine image data, stores determination history data including a result of determination in its memory when the result indicates that the image data are prohibited to be copied, and transfers the determination history data to a digital copying machine of a requesting end, and also transfers the determination history data automatically or as requested to other digital copying machine, a central image formation control unit or a host computer of the service center. As a result, an inhibit copy action can be prevented even when a digital copying machine being used within the system is not provided with an image determining function, thereby providing a security system which can inform others of an occurrence of an illegal or dishonest action at real time.

Also, between seal materials formed along respective adjacent sides of the adjoining TFT substrates connected to each other, a bonding agent is injected. The bonding agent connects to each other the TFT substrates on the sides, and also contacts with the counter substrate.

Abstract: A photosensitive body for electrophotographical use has a conductive base body and a marking area provided thereon. The maximum surface roughness of a photosensitive layer provided right on the marking area is specified not to exceed 2.5 &mgr;m. And also, a ratio of the optical reflective index of the marking area to the optical reflective index of the non-marking area is specified to be in a range of 0.3 to 0.7. In this manner, even when the photosensitive layer is thin (not exceeding 25 &mgr;m), it is possible to prevent problems such as inadequate cleaning and toner falling. Hence, it is possible to offer a photosensitive body for electrophotographical use which can constantly produce high quality copied images.

Abstract: A method of manufacturing electrophotographic toner according to the present invention includes the step of mixing at least toner particles and an additive for a predetermined mixing time to produce the toner, with the predetermined mixing time being set within a range from a first mixing time, at which chargeability of the toner (which changes according to the duration of mixing of the toner particles and the additive) shows a singular point, through a second mixing time, at which preservation of the toner (which also changes according to the duration of mixing) shows a singular point. By this method, a mixing time which maximizes the effects of the additive can be easily set. Accordingly, using a method simpler than conventional methods, a toner can be obtained which has good characteristics with regard to both chargeability and preservation.

Abstract: In a switching power source of the RCC system in which excited energy, accumulated in a transformer during an on-period of a main switching element, is outputted to the secondary side during an off-period, and a ringing pulse, which appears in a control coil of the transformer upon completion of the output, is fed back to the gate of the main switching element through a capacitor used for cutting a dc so that the main switching element is on-driven, a bias resistor is interpolated between the capacitor and the gate, and during the stand-by state, a control transistor is turned on, with the connecting point between them being connected to a main power-source line in a low level through a series circuit consisting of a diode, Zener diode and a resistor. Thus, a higher charge is allowed to accumulate in the capacitor, and the ringing pulse is reversely biased by the charge so as not to cause the re-starting.

Abstract: An image display device includes a display panel provided with a light-shield on a portion shifted upward from a center in a thickness direction and a display panel provided with a light-shield on a portion shifted downward from a center in a thickness direction, the display panels being connected adjacent to each other. The light-shields of the two display panels are overlapped with each other with respect to the entire region between the display panels, thus completely sealing a gap between the display panels by the light-shields. This prevents leakage of light between the display panels even when display panels having large profile irregularity on edge surfaces are connected adjacent to each other. As a result, an image display device capable of displaying a natural image on a large screen is realized.

Abstract: A magneto-optical recording medium has a recording layer made of a perpendicular magnetization film, and a readout layer which is in an in-plane magnetization state at room temperature and changes into a perpendicular magnetization state with a rise in temperature. When the magneto-optical recording medium is irradiated with a light beam, the readout layer separates into three regions: a region in an in-plane magnetization state, a region in a perpendicular magnetization state, and a region having a temperature not lower than the Curie temperature thereof. Only the region in the perpendicular magnetization state allows copying of the magnetization of the recording layer. Therefore, even when the diameter and intervals of recording bits on the recording layer are very small, it is possible to reproduce a target recording bit separately from a recording bit adjacent to the target recording bit.
