A multi-thread processor includes a plurality of hardware threads each of which generates an independent instruction flow, a first thread scheduler that outputs a first thread selection signal, the first thread selection signal designating a hardware thread to be executed in a next execution cycle among the plurality of hardware threads according to a priority rank, the priority rank being established in advance for each of the plurality of hardware threads, a first selector that selects one of the plurality of hardware threads according to the first thread selection signal and outputs an instruction generated by the selected hardware thread, and an execution pipeline that executes an instruction output from the first selector. Whenever the hardware thread is executed in the execution pipeline, the first scheduler updates the priority rank for the executed hardware thread and outputs the first thread selection signal in accordance with the updated priority rank.

A door opening-and-closing apparatus for a vehicle includes a rotatably driven drum, a first cable and a second cable, which cables are wound around the drum, a rotating shaft, a first pulley supported by the rotating shaft, a second pulley supported by the rotating shaft, an attachment member supporting the rotating shaft, a rigid protruding portion integral with one of the first and second pulleys, and an annular recessed portion integrally formed in the other one of the first and second pulleys. When the first and second pulleys are correctly assembled on the rotating shaft, a relative rotation between the first and second pulleys is allowed, and when the first and second pulleys are not correctly assembly on the rotating shaft, the predetermined length of the rotating shaft is not sufficient to support both the first and second pulleys.

An image defect inspection apparatus includes a supply unit, an acquiring unit, an inspection unit and an adjustment unit. The supply unit supplies a test image corresponding to an inferred image defect regarding an image forming unit that forms an image on a recording material, to the image forming unit to form the test image on the recording material. The acquiring unit acquires a scanned image obtained by scanning the recording material on which the test image is formed. The inspection unit compares the scanned image acquired with the test image and inspects as to whether or not the inferred image defect is in the scanned image. The adjustment unit adjusts a value of a setting item which is defined as an adjust target regarding the inferred image defect, so as to enhance detectability of the inferred image defect in the inspection.
