Title: Method and device for input and output control
Inventor: IKEDA MITSUO
IPC: G06F13/00
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To efficiently transfer data by counting the wait time before starting data is transferred and annunciating the time-out of a bus occupation time the counted wait time later. SOLUTION: When the input/output control unit 150 acquires the right to use a bus and start operating as a bus master, a bus master timer counter 153 begins counting the bus occupation time. Further, a wait time counter 155 starts clocking the wait time to count the time from the start of operation of a read instruction for data to the start of transfer of the starting data. A time-out detecting and delaying circuit 152 informs an input/output interface circuit 152 of the time-out with a delay of the time counted by the wait time counter 155 when the counted time of the bus master timer counter 153 reaches a previously set bus occupation time.

Filed: 1988-02-22
Abstract: PURPOSE:To obtain such a phosphor panel that its humidity proofing property is excellent and the light transmittance of its phosphor layer is high and the sensitivity and clearness of the layer do not decline by forming one of the protecting layers of an Si compound containing N. CONSTITUTION:A layer 3 made principally of an Si-compound containing N is directly formed on a phosphor layer 2 formed on a supporting body 1 by a vapor-phase depositing method. In this case, conditions, under which cracks are hardly produced in the phosphor layer 2 and its surface and the SiN layer 3, are selected. It is derable to set the thickness of the SiN layer 3 to such an extent that just flatly covers the uneven surface of the phosphor layer 2 and, usually the thickness is 0.01-50mum. When the thickness of the SiN layer 3 is <=0.01mum, an island structure is formed or the uneven surface of the layer 2 cannot be covered completely and, therefore, the surface of the layer 2 cannot be protected. On the contrary, when the thickness is >=50mum, crack tend to be produced due to the internal stress of the SiN film 3.
