摘要： A video image storage device comprises a signal input means capable of analog-to-digital conversion of input video signals including various types of scanning lines such as different numbers of scanning lines, a frame memory means capable of memorizing image signals and signal output means. The video image storage device further comprises an input signal generating means, an output signal generating means and a frame memory control means. The input signal generating means comprises a N multiplying circuit capable of N multiplying horizontal synchronizing pulses. The number of N in a dividing circuit can be arbitarily determined by the relation between effective image period and blanking period, and thus the video image storage device can store input video signals having different scanning line numbers which depend upon the types of diagnostic modalities.

摘要： A synchronizing signal generating circuit is incorporated in a digital image storing device. When a plurality of video signals composed of different numbers of scanning lines and issued from television cameras of different types of various diagnostic apparatus are converted from analog to digital signals and stored per frame in an image memory in the digital image storing apparatus, sampling pulses for an A/D converter which are synchronous with the horizontal synchronizing signals of the video signals and field discriminating signals relative to odd-numbered fields and even-numbered fields, among composite synchronizing signals, are generated by using an N-multiplier including an equalizing pulse remover controlled by an F/V converter and a field discriminating circuit with a field discriminating time constant being automatically controlled by the F/V converter. The video signals are stored per frame in the image memory on a real-time basis by utilizing the sampling pulses and the field discriminating signal.

摘要： A roller for transporting sheet-like material is manufactured by forming a cylindrical resin layer on the periphery of a preheated aluminum pipe, cutting the aluminum pipe covered with the resin layer to a desired size, and joining coaxially oriented shaft end members to both ends of the cut aluminum pipe. The resin layer can be covered on the periphery of the aluminum pipe by use of an extrusion molding machine. A contoured surface on the pipe or an adhesive can help the resin adhere to the pipe. The roller thus manufactured has high stiffness, roundness, less runout and good dimensional stability over a wide temperature range. The weight of the roller is light and maintenance of a rack which is installed with the rollers by the user is easy.
