    摘要: A tap drive unit for machine tools, which is coupled to the machine-head of the machine tool such as a machining center, includes a driver detachably coupled to a main spindle of the machine tool so as to be rotated with the main spindle, a support member for rotatably supporting the driver, the support member being fixedly mounted on a stationary portion of the machine tool when the driver is coupled to the main spindle of the machine tool, a tubular guide member supported by the support member so as to be concentric with the driver, and a rotational shaft on one end of which a tap is mounted. The guide member is axially moved when a load larger than a predetermined value acts on it. An internal thread is formed in the inner periphery of the guide member. An external thread is formed in the outer periphery of the rotational shaft so as to be threadably engaged with the internal thread. When the main spindle of the machine tool is rotated, the rotational shaft is axially moved in accordance with the pitch of the tap by the interaction of the internal and external threads. Obstruction of the downwardly axial movement of the tap applies a load upon the guide member which then moves upwardly and operates a mechanism to reverse the direction of the spindle.

    摘要: Air fuel ratio sensor for use in an exhaust gas purification system for an internal combustion engine. The sensor has an outer and inner cover 12 and 13 for protection of lead wires 16, 18 and 19 to a detecting element 3 and a heater 5 of the sensor, a rubber seal for 2 for obtaining a sealing between the covers and the lead wires and a water repellent filter 36 for obtaining a seal between the inner and outer covers 12 and 13, while keeping an air ventilation capability of the space inside the covers. For receiving the lead wires 16, 18 and 19, the seal 2 is formed with holes 20such that the minimum thickness between the holes and the minimum thickness between the hole and an outer surface of the seal is 1 mm or more. A crimping of the outer cover 12 is done so that a deformation of the seal 2 in a range between 10 to 20% of the outer diameter is obtained.A crimping of the outer cover 12 is further done at a first section 12A at a larger force for fixation of the outer cover 12 to the inner cover 12 and at a second section 12B at a smaller force for holding the water repellent filter 36 between the outer and inner covers. In the crimping, the crimping at the first section is completed simultaneously or earlier from the completion of the crimping at the second section.
