    • A rotary pump such as a trochoid pump is composed of a housing and a rotating structure including an inner rotor and an outer rotor. The rotating structure is rotatably enclosed in a rotor space formed in the housing. The rotor space is divided into a low pressure space communicating with an inlet port and a high pressure space communicating with an outlet port by a pair of peripheral seals disposed in radial grooves formed in an inner periphery of the housing and by a side seal disposed in an axial space between the rotating structure and the housing. The side seal is disposed in the axial space not to cover sidewalls of the radial grooves belonging to the high pressure space, so that the side seal is bent by the pressure in the high pressure space to effectively seal the axial space.

    • A high-capacity jukebox device for storing and accessing computer readable media. The present invention comprises a 1394-to-ATAPI bridge for coupling to other devices via an IEEE 1394 bus, an ATAPI drive coupled to the ATAPI bridge for communicating with the other devices, and a jukebox controller for controlling the robotics mechanism of the jukebox device. Significantly, according to one embodiment of the present invention, the ATAPI drive comprises a first serial port and the ATAPI jukebox controller includes a second serial port coupled to the first serial port for communicating with the ATAPI drive. In this way, the expensive conventional SCSI LSI and SCSI firmware are eliminated from the jukebox controller, effectively lowering the manufacturing and development costs of the jukebox of the present invention. An additional benefit is that ATAPI drives are less costly than SCSI drives and are more widely available. Since most commercially available embedded processors include a serial interface, implementation cost for such a design is also low, and modifications to existing ATAPI drives are also minimal. Another benefit of the jukeboxes of the present invention is that a large number of them can be daisy-chained together.
    • 用于存储和访问计算机可读介质的大容量点播机设备。 本发明包括一个1394-to-ATAPI桥接器,用于通过IEEE 1394总线耦合到其它设备,耦合到ATAPI桥接器的ATAPI驱动器与其他设备进行通信;以及自动点唱机控制器,用于控制自动点唱机设备的机器人机构 。 重要的是,根据本发明的一个实施例,ATAPI驱动器包括第一串行端口,并且ATAPI点播机控制器包括耦合到第一串行端口的用于与ATAPI驱动器进行通信的第二串行端口。 以这种方式,从点播机控制器中消除了昂贵的常规SCSI LSI和SCSI固件,从而有效地降低了本发明的点播机的制造和开发成本。 另外一个好处是,ATAPI驱动器比SCSI驱动器成本更低,而且更广泛的可用。 由于大多数市售的嵌入式处理器包括串行接口,因此这种设计的实施成本也很低,对现有ATAPI驱动器的修改也很少。 本发明的点播机的另一个好处是它们中的大量可以被菊花链连接在一起。
