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.

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.

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.

摘要:
A method for sequentially controlling the operation of a microwave-excited oxygen plasma surface treatment apparatus in order to improve and control the quality of surface treatment. The pressure within a reactor (10) is continuously monitored and measured and a first pressure signal is issued when the pressure is reduced to a predetermined first level, whereupon flow control valves (52, 54) are opened to allow oxygen gas to flow through microwave discharge tubes (34) into the reactor (10). A second pressure signal is issued when the pressure increases to a second pressure range and microwave power generators (20, 22) are energized to excite the oxygen flowing therethrough. The plasma density is continuously monitored and measured, preferably in terms of the luminous intensity of the plasma, the amount of reflected microwave power, or a combination thereof. The plasma surface treatment is terminated after a timed duration.
