    • A flat shaped header having a heat receiving side is attached to a semiconductor element mounted on a circuit board. The header having the heat receiving side is connected to another header having a heat receiving side attached to a plurality of heat radiating fins so as to form a heat exchanging radiator which heat radiating fins are installed at a peripheral portion of a body of electronic equipment. The heat generated by the semiconductor element is transmitted by liquid moving between the headers via flexible tubes and then to the heat radiating fins, which heat is discharged outside of the body of equipment. Since the flat shaped header and the flexible tubes are employed, a high heat generating semiconductor element and the heat radiating fins are thermally connected with ease without being influenced by the configurational condition in the equipment even when many semiconductor elements are mounted inside a small space.
    • 具有热接收侧的扁平头部安装在安装在电路板上的半导体元件上。 具有热接收侧的集管连接到具有附接到多个散热片的热接收侧的另一个集管,以形成散热片安装在电子设备主体的周边部分的散热片。 由半导体元件产生的热量通过液体通过柔性管在集管之间移动,然后传递到散热片,热量被排放到设备本体外部。 由于使用扁平形的集管和柔性管,因此即使在许多半导体元件安装在小空间内的情况下,高发热半导体元件和散热片也容易热连接而不受设备的结构条件的影响。

    • A limited current type oxygen sensor comprises a solid electrolyte element formed from material having high oxygen-ion conductivity such as yittria-stabilized zirconia. Electrodes are provided on the top surface and the bottom surface of the element and are formed by calcining a mixture of small ceramic particles that are relatively sinter-retardant as compared with oxygen-ion conducting ceramics, of 200 .ANG. in average particle size fine precious metal particles, and a binder. A cover is provided over the second electrode and the cover includes at least one diffusion orifice that permits ambient gas to diffuse toward the second electrode. The dry-gas-based and humid-gas-based oxygen content of the gas is determined by applying a first voltage less than the theoretical water decomposition voltage and a second voltage greater than the theoretical water decomposition voltage to the electrodes to generate corresponding currents associated with the oxygen-ions which flow through the electrolyte element between the first electrode and the second electrode. A heater may be buried in the electrolyte element to increase the flow rate of oxygen ions between the electrodes.
    • 有限电流型氧传感器包括由具有高氧离子传导性的材料形成的固体电解质元件,例如氧化钇稳定的氧化锆。 电极设置在元件的顶表面和底表面上,通过煅烧与氧离子传导陶瓷相比具有相对阻燃性的小陶瓷颗粒的混合物形成,平均粒度细的贵金属为200埃 颗粒和粘合剂。 覆盖物设置在第二电极上方,并且盖包括允许环境气体朝向第二电极扩散的至少一个扩散孔。 通过向电极施加小于理论水分解电压的第一电压和大于理论水分解电压的第二电压来确定气体的干气基和湿气基氧含量,以产生相应的电流 其中氧离子在第一电极和第二电极之间流过电解质元件。 加热器可以被埋在电解质元件中以增加电极之间的氧离子的流速。
