  • Patent number: 8344895
    Abstract: There are provided a photoelectric sensor and a photoelectric sensor system in which received light quantities of a plurality of photoelectric sensors are displayed in an integrated manner, and slight variation in the received light quantity that has nothing to do with a detected condition of a workpiece is ignored and a photoelectric sensor with abnormity is easily found out. Upon acceptance of an instruction to execute scaled display by a control unit of a photoelectric sensor, a scaling adjustment ratio is calculated by assigning the received light quantity to a target value set to be greater than a display upper limit while executing the scaled display. A received light quantity that is subsequently obtained is scaled based on the calculated scaling adjustment ratio to obtain a received light quantity after the scaling.

The bit line selector 14s selects one bit line and couples it to the page buffer unit circuit 14u. The latch L1 temporally stores the data which are read out from the memory cell of the selected bit line, and then outputs the data through the latch L2 or L3. On the other hand, the latch L1 temporally stores the programming data inputted through the latch L2 or L3, and after that outputs it to the memory cell of the selected bit line for programming.

  • Patent number: 8010688
    Abstract: A content distribution system distributes a content key and content use conditions for controlling a content use in a client apparatus to the client apparatus, via a communication channel, from either a multicast distribution server or a unicast distribution server. A content distribution management server determines by which distribution method to send the content key and content use conditions of each content according to an attribute of the content (a compression format, a compression ratio, a content holder, and the like). An encrypted content distribution server distributes only encrypted content whose content key and content use conditions are to be distributed by the unicast, and the multicast distribution server distributes encrypted content whose content key and content use conditions are superimposed by the multicast.
