  • Publication number: 20220262779
    Abstract: A semiconductor device includes a light-emitting element, a light-receiving element, an input-side terminal, a first switching element, a first lead and a resin package. The first lead includes a first mount bed and a first output-side terminal, the first switching element being mounted on the first mount bed. The resin package seals the light-emitting element, the light-receiving element, and the first switching element. The resin package includes first and second side surfaces opposite to each other. The input-side terminal protrudes from the first side surface. The first output-side terminal protrudes from the second side surface. The first switching element is sealed at a center between the first and second side surfaces. The first mount bed is arranged in a direction along the second side surface so that a side surface of the first mount bed is positioned between a center of the resin package and the first output-side terminal.

  • Patent number: 10216457
    Abstract: An information processing apparatus includes a controller, a first storage unit, a second storage unit, and a classification unit. The controller stores pieces of information retained in a memory on a nonvolatile storage device and, upon startup, makes the information processing apparatus return to a state before power-down. The first storage unit is part of the nonvolatile storage device and stores some pieces of information among the pieces of information retained in the memory. The second storage unit is part of the nonvolatile storage device and stores pieces of information different from those stored on the first storage unit among the pieces of information retained in the memory. The classification unit classifies the pieces of information retained in the memory. The controller stores the pieces of information retained in the memory on the first storage unit or the second storage unit in accordance with classification performed by the classification unit.

  • Patent number: 9594701
    Abstract: An information processing apparatus includes first and second central processing units, a communication unit, and a memory. The first and second central processing units operate based on first and second operating systems, respectively. The communication unit controls communication between the first and second operating systems. The memory includes first and second memory areas used respectively by the first and second operating systems. The first operating system includes a memory access requesting unit. The memory access requesting unit sends, to the second operating system via the communication unit, a request to write information to be moved from the first memory area to a virtual memory and a request to read information to be moved from the virtual memory to the first memory area. The second operating system writes to and reads from the second memory area, the information indicated by the write and read requests, respectively.

  • Patent number: 8934211
    Abstract: A solenoid control device executes feedback control such that a drive current for a solenoid follows a target current, by driving, through PWM, a MOSFET provided on a power supply line to the solenoid. An overcurrent detection circuit that outputs an overcurrent detection signal when the drive current for the solenoid reaches an overcurrent determination current value is provided, and it is determined whether an overcurrent is generated. Whether a short-circuit occurs between both terminals of the solenoid is determined by monitoring whether the overcurrent detection circuit is repeating an output of the overcurrent detection signal and a stop of the output of the overcurrent detection signal.
