Abstract: An electrically driven power steering apparatus is structured such that a large impact on a rack shaft (22) occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing (25) of a presser member (30) becomes zero, a rotation of the presser member (30) is hindered by caulking c at a thin plate member (30b). Therefore, the presser member (30) does not slacken, and a predetermined axial force can be given again to the ball bearing (25) when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.

Abstract: A memory device testing apparatus transfers at high speed a fail signal from a failure analysis memory unit 100 to a memory failure remedy analysis unit 200. The failure analysis memory unit 100 has a data storage memory 110 and a compact memory 120. The data storage memory 110 is divided into at least two sub address spaces. The divided sub address spaces are assigned to the addresses in the compact memory 120. An address generation control unit reads data stored in the compact memory 120. An address generation unit 132 generates a memory address signal 143 based on a sub address signal 141 and a detail address signal 142. The detail address signal 142 is incremented by the address generation control unit 125. The data in the sub address space storing the fail signal is transferred to the memory failure remedy analysis unit 200. If the data read from the compact memory 120 does not contain failure information, the data stored in the corresponding sub address space is not transferred.
