摘要： A gradient radiation image conversion sheet, comprising a protective layer a fluorescent layer and a support layer, and the transmissions of said protective layer and/or said fluorescent layer are partially changed and the dots of the print of said gradient patterns and the border between the printed area and the unprinted area are blurred. The gradient image conversion sheet has a gradation area in which the change in transmission is extremely smooth and a speed ratio which may be set in a relatively wide range, and the sheet can be produced through a mass-production system to give products of constant quality.

摘要： A dynamic memory device comprises a dynamic memory circuit, an input buffer circuit for temporarily storing data each time it is received from a source external to the device; an output buffer circuit for temporarily storing data each time it is read out from the dynamic memory circuit and for outputting the stored data in a unit of a predetermined number of words each time a request for reading is made; and a control circuit for controlling the input and output buffer circuits so that reading and writing operations can be performed independently of a refreshing operation.
