摘要:
A method of surface treatment and an apparatus used in said surface treatment are provided in the present invention.Said method comprises dipping a surface-to-be-treated of an article in a treating liquid, moving said article in said treating liquid, letting the treating liquid flow in the reverse direction against said moving, spraying the treating liquid on the surface-to-be-treated of the article before and/or during said dipping and gush-spraying the treating liquid on the treated surface after said dipping; and said apparatus comprises a tank filled with a treating liquid, spraying tools arranged above and/or in said treating liquid in the front part of said tank, means of overflow formed in the front end of the tank, a container receiving the treating liquid overflowing from said means, a path recirculating the treating liquid from said container to the tank and a spraying tool arranged in the rear part of the tank.
摘要:
An apparatus for applying surface treatment on an object-to-be-treated which is continuously moved in a treating liquid usually by a hanging conveyor. The apparatus is provided at the bottom portion of a treating vessel with one or more hoppers, which function to collect the deposited sludge for exhausting the same through the lower portion of the hoppers outside the treating vessel. Further, the apparatus is provided with a plurality of slant plates disposed above the bottom of the treating vessel, being inclined in the same direction, with a predetermined inter-distance among them, so as to facilitate sludge produced in the vessel to be gradually deposited down on the bottom thereof.

A substantially cylindrical socket (10) and a plug (20) to be inserted into the socket (10) are provided. The socket includes a string opening (11), a plug opening (12), an accommodation section (13) in communication with the string opening and the plug opening, a plurality of holding sections (14) for holding string ends (1A) accommodated in the accommodation section, and a widening section (17). The plug (20) is provided with a plurality of pressing legs (24) capable of being widened toward the respective holding sections. The widening section abuts to the pressing legs when the plug is almost fully inserted into the socket (i.e. when at least substantially more than half of the plug is inserted) to press the string ends to the holding sections.

An elongate article coupler comprises a pair of fitting parts for severally retaining end parts of the elongate articles and a connecting part disposed between the fitting parts and adapted to interconnect the fitting parts, the connecting part having a breaking part adapted to be broken under a tension exceeding a prescribed level. In accordance with one embodiment of the modification, the coupler comprises a pair of fitting parts each including one of a pair of engaging parts adapted to form mutual engagement and break the engagement under a tension exceeding a prescribed level. In accordance with another modification, the coupler comprises one or more of fitting parts and retention cancelling means adapted to induce retention of the elongate article in cooperation with the fitting parts and cancel the retention of the elongate article when a tension exceeding a prescribed level is exerted on the elongate article.

A cord fastener comprises a fastener body having a hollow and a pair of aligned first cord insertion through-holes communicating with the hollow, and a slide slidably inserted in the hollow of the fastener body and having a pair of aligned second cord-insertion through-holes. The slide has a head, a pair of resilient legs extending downwardly from a lower surface of the head and a pair of supporting arms extending downwardly from the lower surface of the head. Each of the second cord-insertion through-holes has an upper portion contiguous to the lower surface of the head.

A releasable catch for holding together they body of a bag and a flap of the bag includes a plug member attached to the flap and having a resiliently deformable locking tongue, and a socket member attached at its one end to the bag body and having a gate-shaped locked portion disposed adjacent the one end of the socket member for slidably receiving and thereafter locking the resiliently deformable locking tongue to couple the plug member and the socket member. The locking tongue is tilted toward a backward side of the plug member at a predetermined angle relative to a plane of an attachment portion. When the locking tongue of the plug member is locked into the socket member, the bent plug member tends to turn the socket member about the fixed one end toward the bag body, so that the other or loose end of the socket member is always held in contact with a front surface of the bag body regardless of the content of the bag. The releasable catch thus constructed is sightly in appearance, can be manipulated reliably with utmost ease, and damages neither itself nor another article upon impingement with the latter.
摘要:
A method for the electrodeposition coating of workpieces conveyed in an electrodeposition bath, wherein voltage application means is provided in a plurality of stages in the conveying direction of the workpieces. In the method, the type of workpiece being conveyed is detected, and the length of time to apply voltage to the workpiece in the bath according to the type of workpiece by changing the number of stages to be electrically coupled among the plurality of stages of the voltage application means. By this method, it becomes possible to provide each workpiece with most suitable electrodeposition film thickness even in a line where workpieces having different required film thicknesses are present.
