摘要： A photodetector including: a case including a light receiving surface provided on an upper surface and having a first region that transmits visible light and a second region that transmits less visible light than the first region; a printed circuit board provided to face the light receiving surface; and a plurality of electronic components provided on a light receiving surface side of the printed circuit board and including a first light receiving element configured to detect visible light. The first light receiving element is disposed at a first position of the printed circuit board exposed to the visible light transmitted through the first region. The number of mounted electronic components disposed at the first position is smaller than the number of mounted electronic components disposed at a second position of the printed circuit board other than the first position.

摘要： A load drive device has a load drive unit including an input system electrically connectable to a control power supply and an output system electrically connectable to a load drive power supply. The load drive unit supplies the electrical load with load drive voltage from the load drive power supply via the output system when the control power supply applies control voltage to the input system. A potential difference detection unit detects a potential difference between the control voltage and the load drive voltage. A potential fixing unit fixes a potential at a control system electrical route, connecting the control power supply and the input system of the load drive unit, to a prohibition level that prohibits the output system of the load drive unit from driving the electrical load when the potential difference detected by the potential difference detection unit exceeds a predetermined threshold value.

摘要： A photodetector includes: an upper case including a light receiving portion on an upper surface and a side portion extending downward from the light receiving portion; a printed circuit board facing the light receiving portion; and a lower case including a support portion configured to support the printed circuit board, an opening on one side surface and configured to allow a connector to be inserted therethrough, and a hook on another side surface. The lower case is fitted to the upper case such that at least the printed circuit board and the support portion are surrounded. The upper case has a cut portion configured to prevent interference with the hook when being attached. At least part of the side portion adjacent to the cut portion and on a side of the opening extends up to a lower side of the opening.

摘要： A load drive control circuit includes a drive circuit for driving a load. A control circuit, connected to the drive circuit by diagnostic lines, provides the drive circuit with a control command that specifies an operation state. The drive circuit drives the load in the operation state specified by the control command, generates a diagnostic output including diagnostic notification signals each having an H level or an L level, and provides the diagnostic notification signals of the diagnostic output to the control circuit. A signal output unit outputs first and second diagnostic outputs respectively in response to the first and second control command from the control circuit. A diagnostic line failure determination unit checks whether the first and second diagnostic outputs are both normal to determine whether the diagnostic lines includes a failure or not.
