A waterproof plug includes a cylindrical resin member and a sealing section configured to include an outer circumference section which is provided on an outer face of the resin member and an inner circumference section which is provided on an inner face of the resin member. The outer circumference section intimately contacts to an inner wall face of a cavity of a connector housing, and the inner circumference section intimately contacts to an outer circumference face of an electric wire. An outer circumference face of the resin member is brought into contact with an inner wall face of an electric wire through hole of the connector housing. The resin member has a plurality of protruded claw sections protruding toward the inner circumference section side along a circumference direction of the resin member.

摘要:
A method of manufacturing an annular concentric stranded bead cord, wherein, while rotating an annular core at a fixed position in a peripheral direction, a reel, upon which a lateral wire is wound, repeatedly performs a pendulum swinging movement and a perpendicular movement with respect to the annular core, thereby spirally winding the lateral wire upon the annular core to form a sheath layer. When forming the sheath layer, a fulcrum of the pendulum swinging movement of the reel is determined so that, with reference to a tangential line of a circle of the annular core passing through a winding point where the lateral wire is wound upon the annular core, the lateral wire is wound upon the winding point of the annular core within 15 degrees at a position above the tangential line and within a range of 55 degrees at a position below the tangential line.

The disclosed bead cord which is lightweight and inexpensive and high in formability includes an annular core and a wrap wire helically wrapped around the annular core, the annular core being made of a medium carbon steel or an alloy steel having a lower carbon content and containing specific elements in suitable amounts. The diameter dC of alular core satisfies 1.04≦dC/dS≦1.30 where dS is the diameter of the wrap wire. The wrap wire has a coil diameter DS which is 0.5 to 1.3 times diameter DC of an annular shape of the annular core. The annular core may be formed with a plating layer of an Al—Zn alloy or a thick plating layer of Zn, or the annular core may be made of stainless steel.

摘要:
In an elevator apparatus, a car is mounted with an safety device for bringing the car to an emergency stop. A drive unit for raising and lowering the car is controlled by a drive control portion. A safety control portion detects an abnormality in the elevator and outputs an actuation signal. An electrical actuator portion actuates the safety device in response to an actuation signal output from the safety control portion. A mechanical actuator portion mechanically detects an abnormality in the elevator, and actuates the safety device through mechanical transmission of a control force. In the event of power failure, a backup power source enables functioning of at least the drive unit and of the drive control portion.

摘要:
In an elevator apparatus, a control device obtains car information including at least one of car position information and car speed information based on a main detection signal from a main sensor unit. An auxiliary sensor unit detects arrival of a car at a preset reference position with in a hoistway to generate an auxiliary detection signal. The control device makes corrections to the car information based on the auxiliary detection signal.

An annular metal cord and an endless metal belt are provided which have superior breaking strength and which are easy to be produced.The annular metal cord includes an annular core portion 3 and an outer layer portion 4. The annular core portion 3 is formed by connecting together both ends of a first strand material 1 which is made up of six twisted first metal filaments 5. The outer layer portion 4 is formed by winding spirally a second strand material 2 which is made up of six twisted second metal filaments 6 around the annular core portion 3. The second strand material 2 is wound at a predetermined winding angle relative to a center axis of the annular core portion 3, and a winding initiating end portion and a winding terminating end portion thereof are connected together. Since it is not that six second strand materials 2 are not wound but that the second strand material 2 is wound six rounds, there only has to be the single second strand material 2, and there is only one connecting portion. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.
