  • Patent number: 9183476
    Abstract: A print management apparatus includes a print management unit, a storage unit, and a print controller. The print management unit acquires print information of printing processing performed by an image forming apparatus and performs management of the processing. The storage unit temporarily stores print information acquired by the print management unit. The print controller performs control such that print information that is temporarily stored is transmitted sequentially to the image forming apparatus. Even in a case where the print controller has generated, by mistake, a notification indicating completion of transmission, even though the print controller has not completed transmission of print information, the print management unit detects that there is a page that has not been printed by the image forming apparatus, on the basis of information on the progress of printing from the image forming apparatus.

  • Publication number: 20150280449
    Abstract: A power supply device is capable of transferring AC power in a noncontact manner to a secondary coil of a power receiving device. The power supply device includes an AC power supply that outputs the AC power. The AC power supply includes a DC/AC conversion unit that converts DC power to the AC power, which has a predetermined frequency. A primary coil receives the AC power. A control unit controls the AC power output from the AC power supply. The control unit is configured to suspend the output of the AC power from the AC power supply or decrease the AC power based on input power, input current value, output power, or output current value of the DC/AC conversion unit and a power factor or a current difference of the input current value and the output current value.

  • Patent number: 8952739
    Abstract: A combination circuit generates first and second internal signals according to first and second input signals, respectively. A first master latch circuit selectively captures and holds a scan-in signal and the first internal signal, and generates a first output signal and a first intermediate signal based on the signals thus captured and held. A first slave latch circuit selectively captures and holds the first intermediate signal and the second internal signal, and generates a second output signal and a scan-out signal based on the signals thus captured and held. This arrangement reduces a circuit scale and power consumption of the input circuited provided in a semiconductor integrated circuit to which a scan path test method is applied.

  • Publication number: 20140056094
    Abstract: In a state where a signal (IN) is at “H” and an NMOS transistor (403) is on, when a signal (PCLK) changes to “H” and a PMOS transistor (401) turns off, an output node (N1) becomes coupled to a word-line activation signal (WACTCLK) via the NMOS transistor (403). When the word-line activation signal (WACTCLK) changes to “L,” a word line signal (MWL) changes to “L.” Since the signal (PCLK) is at “H” and the NMOS transistor (405) is on, this NMOS transistor (405) can assist discharging of the word-line activation signal (WACTCLK) to a ground voltage.
