    • An apparatus for compressing/expanding a working gas (compression/expansion apparatus), including: a cylinder; a piston for compressing/expanding said working gas in a working space (front space) of said cylinder; a crank mechanism connected with a piston rod of said piston via an oil seal; a crank chamber for housing therein said crank mechanism and communicating with said cylinder via said oil seal, said apparatus comprising: a first tube allowing for a unidirectional flow of the working gas from said crank chamber to said front space in said cylinder, said first tube having therein an oil filter and a first check valve; and a second tube allowing for a unidirectional flow of the working gas from said front space to a second space (rear space) behind said piston in said cylinder, said second tube having therein a second check valve. In this construction a loop of the working gas is established for pumping the gas from the crank chamber to the rear space of the cylinder via the front space, and then back to the crank chamber via the oil seal between the cylinder and the crank chamber. The passage of the gas through the oil seal helps prevent the lubrication oil from infiltrating directly from the crank chamber into the cylinder along the piston rod.
    • 一种用于压缩/膨胀工作气体的装置(压缩/膨胀装置),包括:气缸; 用于在所述气缸的工作空间(前空间)中压缩/膨胀所述工作气体的活塞; 曲柄机构,其经由油封与所述活塞的活塞杆连接; 用于容纳其中的所述曲柄机构并经由所述油封与所述气缸连通的曲柄室,所述装置包括:允许所述工作气体从所述曲柄室单向流动到所述气缸中的所述前部空间的第一管,所述第一管 其中具有滤油器和第一止回阀; 以及允许所述工作气体从所述前部空间到所述气缸中的所述活塞后面的第二空间(后部空间)的单向流动的第二管,所述第二管中具有第二止回阀。 在这种结构中,建立了工作气体循环,用于经由前部空间将气体从曲柄室泵送到气缸的后部空间,然后经由气缸和曲柄室之间的油封将其返回到曲柄室。 气体通过油封的通道有助于防止润滑油沿着活塞杆从曲轴室直接渗透到气缸中。

    • In an one-chip microcomputer used in an automobile, error correction code data is added to corresponding user data, and then the resulting user data is stored into an EEPROM to correct an 1-bit error contained in this user data. The one-chip microcomputer is arranged by an electrically erasable memory for temporarily storing thereinto externally supplied user data and ECC (error correction code) data corresponding to the user data; a program storage memory for previously storing thereinto a program; and a CPU (central processing unit) for reading the program from the program storage memory so as to produce the ECC data based upon the externally supplied user data, and for sequentially correcting errors contained in the externally supplied user data by using the produced ECC data corresponding to the externally supplied user data.
