Abstract: Provided an electrophotographic electro-conductive member that can stably suppress an occurrence of fogging in an electrophotographic image. The member comprises a support having an electro-conductive outer surface, and an electro-conductive layer on the outer surface of the support, the electro-conductive layer having a matrix including a cross-linked product of a first rubber, and domains dispersed in the matrix, the domains each includes a cross-linked product of a second rubber and an electro-conductive particle, at least some of the domains is exposed to the outer surface of the electro-conductive member to constitute protrusions on an outer surface of the member, the outer surface of the electro-conductive member is constituted by the matrix and the domains exposed to the outer surface of the electrophotographic electro-conductive member, the electrophotographic electro-conductive member has an impedance of 1.0×103? or more and 1.0×108? or less, and some of the domains satisfy two specific requirements.

Abstract: A video data display board, device or method for inputting and displaying video data including vertical blanking interval data containing character data and other image data than the vertical blanking interval data. The video data display device has a data transfer circuit capable of transferring both of the data to devices different from each other, so that the processing of character information and image data are performed by using the different devices which perform an appropriate process according to the property of the data. The processed character and image data are displayed on a graphic display screen simultaneously.

Abstract: A video data processing device which includes a bus, a central processing unit (CPU), a first scaling unit which is coupled to the bus and has an input unit for inputting image data from an external device, and a second scaling unit which is coupled to the bus. The CPU selectively controls the first scaling unit to convert the image data when an amount of the image data is decreased by a conversion performed by the first scaling unit, and selectively controls the second scaling unit to convert the image data when an amount of the image data is increased by the conversion performed by the first scaling unit.

Abstract: Using an LiTaO.sub.3 or LiNbO.sub.3 substrate, a proton exchange layer in a grid pattern, namely sprout areas of polarization inversion, is firstly, formed on the surface of said substrate and, after formation of the pattern, heat treatment is executed at a temperature of 200.degree. C. or more and for a holding time of 10 minutes or less. By maintaining the temperature gradient up to said heat treatment point at 50.degree. C./min. or steeper and by maintaining the temperature decrease rate from said heat treatment point at 50.degree. C./min. or faster, polarization inverted areas are formed downwards from the proton exchanged areas, while in addition to making the top ends of said polarization inverted areas into an acute angle, the depth/weight ratio of the polarization inverted grids being formed is made to exceed 1, thus enabling the production of a high-efficiency SHG element.

Abstract: A runner-strip and articles attached to the runner-strip are molded into a piece in an injection molding unit. The piece is pulled out of the injection molding unit by a pulling-out unit. A back end of the runner-strip is left in the injection molding unit and is continued to a subsequent runner-strip to form a series of the pieces. The articles are separated from the runner-strip by providing a shock to both sides of the articles. Collecting units are provided for collecting the articles and the runner-strip.
