Abstract: Provided is a bumper cap to be attached to a shock absorber main body, and includes a cover part having an opening at one end, having a bottom part and a through hole penetrating the bottom part at another end, and configured to cover the shock absorber main body, and a plurality of protruding parts protruding from the bottom part of the cover part toward the opening side, and in which a gap is formed between the adjacent protruding parts, in which a suppression part configured to suppress a rotation of a fluid, which has flowed into a space between the inside of the cover part and the shock absorber main body from an outside of the cover part through the through hole, in the cover part is further provided.

Abstract: A multiprocessor system includes a random access memory (85) for storing a processor number data specifying that an interrupt from any of a plurality of devices (6l to 6m) to any one of a plurality of processors (1l to 1n) is permitted. If and when an interrupt request signal is applied from the device (61) to an interrupt controller (8), a processor number data indicating a processor which the device (61) can interrupt is read out from the random access memory (85). The interrupt controller (8) applies an interrupt signal to a processor (11), for example, according to the processor number data. Correspondingly, the processor (11) applies a bus request signal to a bus controller (7). According to the bus request signal, the bus controller (7) controls a bus selecting circuit (3) to connect a local bus (21) of the processor (11) to a common bus (5).
