The compressor (10, 100) comprises a body portion (11, 110) and a reservoir (13, 150), wherein the reservoir (13, 150) is arranged below the body portion (11, 110), an interlayer (12, 160) is arranged between the reservoir (13, 150) and the body portion (11, 110), the interlayer (12, 160) is provided with a vacuum cavity (161) and an air extraction hole (170) in communication with the vacuum cavity (161), and the air extraction hole (170) is suitable for vacuumizing the vacuum cavity (161). The structure can effectively prevent heat from the body portion (11, 110) from being transferred to the reservoir (13, 150), thereby improving the cooling capacity of the compressor (10, 100), and achieving individual vacuumizing of the compressor (10, 100).

A simulator abnormality determination system according to an embodiment of the present invention determines an abnormality of each simulator by using a controller that executes processing of synchronizing one or a plurality of simulators with one another. The controller causes each simulator to: start simulation processing to be executed in a specific period; transmit, to the controller in specific cycles, a keep-alive notification indicating that the simulator is alive until the simulator completes the simulation processing; and transmit, to the controller, a completion notification indicating completion of the processing when the processing is complete. The controller determines that a simulator that has transmitted a keep-alive notification is normal when receiving the keep-alive notification in specific cycles, determines that a simulator that has transmitted a completion notification has completed the processing when receiving the completion notification, or determines that a simulator not determined to have completed the processing is abnormal when a keep-alive notification is not transmitted from the simulator in specific cycles.

A vehicle lighting device includes a socket; a substrate; and one first and four second light emitting elements. A square luminance distribution region is defined on light irradiation sides of first and second light emitting elements. A center of distribution region overlaps central axis of device. Distribution region is equally divided into four square first regions whose corners overlap center of distribution region. Each of first regions is equally divided into nine square second regions. A length of one side of second region is 0.8 mm. Luminance of distribution region is 90% or more of a total luminance of light emitted from device. In twenty second regions arranged along sides of distribution region, luminance of one second region is 2% or less of total luminance. In sixteen second regions provided inside twenty second regions, luminance of one second region is 3% or more and 10% or less of total luminance.

A belt drive device includes a drive unit, a detection unit, a blade, and a control unit. The drive unit rotates an endless belt. The detection unit detects a position of a connection portion in which both ends of a reinforcing tape, which is provided on an outer surface of an edge of the belt in a width direction orthogonal to a rotation direction of the belt, in a longitudinal direction along the edge of the belt are overlapped and connected. The blade comes into contact with an outer surface of the belt and an outer surface of the reinforcing tape and is provided to extend in the width direction. The control unit controls driving of the drive unit based on a detection result obtained by the detection unit such that when the drive unit rotates the belt by a constant length in a reverse direction from one end of the reinforcing tape overlapped inside toward the other end of the reinforcing tape overlapped outside at the connection portion from a state in which the belt is stopped, the drive unit rotates the belt in a forward direction to a rotation position where the other end of the reinforcing tape does not come into contact with the blade by a reverse rotation and stops the belt before the belt is reversely rotated.
