    • An air atomizing electrostatic coating gun which atomizers a liquid paint by using air flows and thereafter applying atomized liquid paint to an object to be coated by using an electrostatic force. In this coating gun, all of a rod valve, a driving piston, an air cylinder and valve support members of a needle valve device are made of insulating materials having good insulating properties, and an electrode for charging paint particles is attached to the valve. A nozzle-needle valve assembly which is integrally constructed by attaching a paint nozzle to a cylindrical extension of the air cylinder which is formed at a front end portion thereof, is inserted and fitted into a generally cylindrical cavity in a front end portion of the gun body from the front side thereof. An integral molded body incorporating a direct current high-voltage power source is formed by molding a synthetic resin having good insulating properties to embed therein a boosting high-voltage transformer, a rectifier type direct current high-voltage generator and a spiral-wound flat high-resistance element, and this integral molded body is detachably attached and fixed inside of the gun body by inserting it into a cavity formed in a rear end portion of the gun body from the rear side thereof.

    • A highly-viscous material coating apparatus for use, e.g. in an automobile coating process, to coat a joint of a workpiece, may be mounted on a robot. It provides improved operation where the workpiece provides a reference surface parallel to the joint, where the workpiece provides a reference surface displaced from the joint at varying distances along the length of the joint, and where the workpiece provides no reference surface. Where a reference surface is available, an extendable spring-biased guide pin of the apparatus moves along the reference surface, and any positional errors are compensated-for by action of the spring. If the distance between the reference surface and the joint varies, the varying distance may be compensated for by various disclosed practices. The apparatus also can be used where no reference surface is provided by retracting the guide pin with respect to the nozzle and by controlling the robot so as to direct the nozzle to the joint. A conventional nozzle may be adapted to dispense a highly-viscous liquid without splattering or otherwise marring the surface of the workpiece by providing the nozzle with a frusto-conic recess.
    • 一种用于使用的高粘度材料涂覆装置。 在汽车涂装工艺中,涂覆工件的接头可以安装在机器人上。 它提供了改进的操作,其中工件提供平行于接头的参考表面,其中工件提供沿着接头的长度以不同距离从接头移位的参考表面,并且其中工件不提供参考表面。 在参考表面可用的情况下,该装置的可伸长的弹簧偏置引导销沿着参考表面移动,并且通过弹簧的作用来补偿任何位置误差。 如果参考表面和接头之间的距离变化,则可以通过各种公开的做法来补偿变化的距离。 该装置还可以用于通过相对于喷嘴缩回引导销并且通过控制机器人以将喷嘴引导到接头而不提供参考表面。 常规喷嘴可以适于通过为喷嘴提供截头圆锥凹槽而分配高粘度液体而不会飞溅或以其他方式损坏工件的表面。

    • In a diesel engine provided with a diesel particulate filter 81 and an exhaust throttle valve 9, noise is decreased that is produced when the exhaust throttle valve is returned back to the fully opened state after a diesel particulate filter 81 has been regenerated by oxidizing and removing the particulate matter deposited thereon. The exhaust system of the diesel engine is equipped with the diesel particulate filter 81 and a catalyst 82 on the upstream thereof, and is further equipped with the exhaust throttle valve 9 on the downstream. The diesel particulate filter 81 is regenerated by operating the diesel engine in a state where the exhaust throttle valve 9 is opened to a small degree. When the regeneration has finished, the diesel engine is run at a decreased rotational speed and, thereafter, the exhaust throttle valve 9 is returned back to the fully opened state. When the engine is run at a decreased rotational speed, the pressure in the exhaust system decreases making it possible to greatly decrease the noise that generates at the time of the opening of the exhaust throttle valve 9.
    • 在设置有柴油机微粒过滤器81和排气节流阀9的柴油发动机中,在通过氧化除去后的柴油机微粒过滤器81再生后,当排气节流阀回到完全打开状态时产生的噪音降低 沉积在其上的颗粒物质。 柴油发动机的排气系统在其上游配备有柴油机微粒过滤器81和催化剂82,并且在下游还配备有排气节流阀9。 柴油机微粒过滤器81通过在排气节流阀9打开的程度较小的状态下操作柴油机来再生。 当再生结束时,柴油发动机以降低的转速运转,此后,排气节流阀9返回到完全打开状态。 当发动机以降低的转速行驶时,排气系统中的压力减小,从而可以大大降低在排气节流阀9打开时产生的噪音。
