Abstract: An on-board device includes: a control unit in which a plurality of virtual devices serve as an operation environment for programs; and a storage unit that stores a virtualization operating system. Each of the virtual devices: includes a communication buffer to which an area from the storage unit is assigned; and writes the communication data addressed to another virtual device, to the virtual device's own communication buffer when communicating with the other virtual device, a management unit that manages the virtual devices: reads out the communication data written to the communication buffer; writes the communication data to a storage area that is accessible to the management unit; and writes the communication data written to the storage area to the communication buffer of the other virtual device. The other virtual device reads out the communication data transmitted from the virtual device, written to the other virtual device's own communication buffer.

Abstract: To provide a shaft seal that is capable of decreasing rotational torque and realizing superior sealing performance. A shaft seal 1 having a ring shape adheres to an outer peripheral surface of a rotational shaft 6 and thereby seals sealed fluid. The shaft seal 1 partitions a gap between the rotational shaft 6 and a housing 7 to which the shaft seal 1 is mounted, into a high-pressure side and a low-pressure side. The shaft seal 1 is an injection-molded body having a generally U-shape in a sectional view about an axial direction. The shaft seal 1 has a seal lip part 2 that is configured to extend to the high-pressure side and slide on the rotational shaft 6, and an outer lip part 3 that is disposed at an outer diametrical side relative to the seal lip part 2. An inclined angle ? of the seal lip part 2 relative to the outer peripheral surface of the rotational shaft 6 is 5-20 degrees. The length L2 of the seal lip part 2 in the sectional view about the axial direction of the shaft seal 1 is 2.0-6.5 mm.

Abstract: A high-precision slide bearing includes a substrate of sintered metal and a synthetic resin layer. The bearing can be used for rotary shafts in compressors of room air-conditioners or in transmissions of motor vehicles and construction machines to support relatively large radial and axial loads. The resin layer is integrally superposed on the radially inner surface of the sintered metal substrate of the slide bearing, which is a cylindrical member. The resin layer is made of a resin composition of an aromatic polyetherketone resin containing a fibrous filler. The fibrous filler is made up of fibers dispersed in the resin layer and oriented such that their length directions intersect the rotational direction of the bearing at angles of 45 to 90 degrees. The resin layer has a thickness of 0.1 to 0.7 mm.
