    • The test design cost of a circuit capable of accessing an external memory is reduced. There is included a built-in self-test circuit for use in testing an external memory separately from a memory controller for performing memory control in response to an access request to the external memory capable of being coupled to a memory interface, and a TAP controller is used to control the built-in self-test circuit and referring to a test result. There is adopted a multiplexer for switchably selecting the memory controller or the built-in self-test circuit as a circuit for coupling to the memory interface in accordance with control information externally inputted through the TAP controller. The built-in self-test circuit programmably generates and outputs a pattern for a memory test in accordance with an instruction inputted through the TAP controller, and compares data read from the external memory with an expected value.
    • 能够访问外部存储器的电路的测试设计成本降低。 包括内置自检电路,用于独立于存储器控制器测试外部存储器,用于响应于能够耦合到存储器接口的外部存储器的访问请求执行存储器控制,以及TAP控制器 用于控制内置自检电路并参考测试结果。 采用多路复用器,根据外部通过TAP控制器输入的控制信息,可选择存储控制器或内置自检电路作为耦合到存储器接口的电路。 内置的自检电路可编程地根据通过TAP控制器输入的指令产生和输出用于存储器测试的模式,并且将从外部存储器读取的数据与预期值进行比较。

    • A rack shaft is supported at three positions including a gear housing receiving an engagement portion between a rack gear and a pinion near one end in an axial direction with respect to a rack housing corresponding to a support body thereof, a housing near the other end, and a hollow tube housing in an approximately center portion of the rack shaft. A bush made of a resin and constituted by a cylinder body is used for supporting the rack shaft by the hollow tube housing in the approximately center portion of the rack shaft. The bush is provided with a plurality of cut grooves extending in an axial direction thereof, and is provided with a curve forming portion substantially supporting the rack shaft and extending toward an inner side in a center portion in the axial direction thereof.
    • 齿条轴支撑在三个位置处,包括齿轮壳体,齿轮壳体相对于与其支撑体对应的齿条壳体在轴向方向上的一端处接收齿条和小齿轮之间的接合部分,在另一端附近的壳体, 以及在齿条轴的大致中心部分的中空管壳体。 由树脂构成的由筒体构成的衬套用于通过中空管壳体在齿条轴的大致中心部分中支撑齿条轴。 衬套设置有沿其轴向延伸的多个切割槽,并且设置有基本上支撑齿条轴并沿其轴向方向的中心部分的内侧延伸的弯曲形成部。
