  • Patent number: 12162709
    Abstract: A post-processing apparatus includes a first conveyor, a second conveyor, a third conveyor, and a conveyance passage corrector. The first conveyor conveys a sheet conveyed along a first conveyance passage downstream from the first conveyor. The second conveyor conveys the sheet along a second conveyance passage. The third conveyor conveys the sheet along a third conveyance passage. The conveyance passage corrector includes a retracting mechanism to retract from a joining position at which the third conveyance passage joins to the first conveyance passage and turns a conveyance direction of the sheet toward the first conveyor when the sheet enters from the third conveyance passage to the first conveyance passage.

  • Patent number: 12027972
    Abstract: A power supply control semiconductor device that generates and outputs a drive pulse to turn on and off a switch, which is configured to intermittently supply a current to a primary winding of a voltage conversion transformer, in response to input of a voltage proportional to the current flowing through the primary winding of the voltage conversion transformer and an output voltage detection signal from a secondary side of the voltage conversion transformer is provided. The power supply control semiconductor device is in a no-lead resin-sealed package. The package includes external terminals including a first terminal as an input terminal, a second terminal provided next to the first terminal, and third terminals that have a lower breakdown voltage relative to the first terminal and are different from the second terminal. An interval between the first terminal and the second terminal is wider than each interval between the third terminals.

  • Patent number: 9291563
    Abstract: FRET measurement uses a FRET probe that includes a probe element X containing a donor fluorescent substance and a probe element Y containing an acceptor fluorescent substance and enables FRET to occur when the probe element X and the probe element Y approach to each other or bind together. The modulation frequency of laser light with which the FRET probe is irradiated is adjusted to an optimum modulation frequency that maximizes a difference between the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET occurs and the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET does not occur.
