    • The present invention provides a hydraulic excavator provided with a dozer device comprising an arm having a rear end connected to a fulcrum portion provided on a lower frame of a lower traveling body, a dozer blade provided at an extreme end of the arm, and a dozer cylinder for swinging the arm in vertical direction, characterized in that the dozer cylinder and the arm are arranged in a state of forming two sides of a triangle as viewed from the side, the arm swings vertically so that the dozer cylinder does not interfere with a bottom of an upper rotating body rotatably mounted on the lower traveling body, and an approach angle when the dozer blade vertically moved by the arm is placed in the highest position is set to 35 degrees or more, thereby capable of securing travelability equal to an excavator without a dozer device.
    • 本发明提供一种具有推土装置的液压挖掘机,该推土机装置具有后端,该后臂与设置在下行进体的下框架上的支点部连接,设置在该臂的末端的推土铲,以及推土机 气缸,用于在垂直方向上摆动臂,其特征在于,推进器气缸和臂布置成从侧面观察形成三角形的两侧的状态,臂垂直摆动,使得推土机气缸不干扰 可旋转地安装在下行进体上的上旋转体的底部,并且当通过臂垂直移动的推土铲叶片位于最高位置时的接近角度被设定为35度以上,由此能够确保与挖掘机等同的行驶性能 没有推土机装置。

    • In a coolant supply method and apparatus for a grinding machine, when an end surface of a workpiece is ground with a grinding wheel end surface of a grinding wheel with coolant being supplied toward a grinding point, a first coolant flow is ejected toward a first position which is on the grinding wheel end surface on an upstream side of the grinding point, and intercepts an air layer rotating to follow the grinding wheel end surface. At the same time, a second coolant flow is ejected toward a second position which is on the grinding wheel end surface and which is closer to the grinding point than the first point, and clings onto the grinding wheel end surface at the second position where the follow air layer has been intercepted by the first coolant flow. Thus, the coolant of a sufficient volume can be supplied to the grinding point where the grinding wheel end surface grinds the end surface of the workpiece.
    • 在用于研磨机的冷却剂供给方法和装置中,当工件的端面用研磨轮的砂轮端面研磨时,其中朝向研磨点供给冷却剂,第一冷却剂流朝向第一位置喷射 其位于研磨点的上游侧的砂轮端面上,并拦截沿着砂轮端面旋转的空气层。 同时,向第二位置喷射第二冷却剂流,该第二位置位于砂轮端面上并且比第一点更靠近研磨点,并且在第二位置附着在砂轮端面上, 跟随空气层已被第一冷却剂流拦截。 因此,足够体积的冷却剂可以被供给到研磨点,其中砂轮端面研磨工件的端面。

    • To provide a probe coil for an NMR apparatus which can transmit and receive high frequency radio waves with improved Q-factor and S/N ratio. As a measure, the probe coil for an NMR apparatus is provided as of a solenoid type formed of magnesium diboride superconductor. As another measure, the probe coil for an NMR apparatus has a plurality of coils using magnesium diboride superconductors connected in series. As further another measure, there is used a magnesium diboride superconductor mixed with metal. As still further another measure, the probe coil for an NMR apparatus is formed by using a single metal selected from gold, silver, copper, aluminum, iron, platinum, palladium, nickel, stainless steel, chromium, magnesium, tantalum, niobium, titanium, zinc, beryllium, tungsten, or cobalt, or an alloy including a plurality thereof.
    • 提供一种能够以改善的Q因子和S / N比发送和接收高频无线电波的NMR装置的探针线圈。 作为测量,用于NMR装置的探针线圈以由二硼化镁超导体形成的螺线管形式提供。 作为另一个措施,用于NMR装置的探针线圈具有使用串联连接的二硼化硼超导体的多个线圈。 作为另一个措施,使用与金属混合的二硼化镁超导体。 作为另一种措施,NMR装置的探针线圈通过使用选自金,银,铜,铝,铁,铂,钯,镍,不锈钢,铬,镁,钽,铌,钛的单一金属形成 ,锌,铍,钨或钴,或包含多个的合​​金。
