A barrel plating method wherein each box containing pieces to be plated is provided with a kanban corresponding to the pieces contained in the box. The kanban of each box is read by an apparatus before the pieces are transferred from the box to a plating barrel, so that a plating coefficient corresponding to the information read from the kanban is retrieved from a host computer in which plating coefficients for various kinds of pieces are stored. The plating coefficient retrieved corresponding to the kanban of each box is proportional to a value of plating current to be supplied to a unit weight of pieces contained in the box. A value of plating current for each barrel is automatically calculated by multiplying the plating coefficient by the measured weight of the pieces put in the barrel. Barrel plating is performed by supplying each barrel with the value of the calculated plating current from power sources that correspond in number to barrels that are subjected to a plating process at a given time.

There is disclosed a guide slider for a window regulator that does not cause to rise an allophone, a awkward movement and a jolt to a rail in which said guide slider is made a slidable movement, wherein said guide slider comprises a substantially lod blank having a substantially spherical head at one tip end thereof and a main body of guide made of thermoplastic resin, wherein further the main body of guide has a receiving and bearing seat in which the head of the blank can be received in such a manner that the axis of the blank becomes coaxial to that of the main body of guide, and the receiving and bearing surface of the main body of guide closely contacts with the surface of the head but the slidably rotational movement of the head in the receiving and bearing seat is permitted.

Disclosed is a nozzle for lubrication, which comprises a substantially oval metallic mounting plate having a bolt-inserting hole at one end of the mounting plate and a plug body-inserting hole with plural protruded pieces at the other end of the mounting plate. A plug body made of a fiber-reinforced thermoplastic is insert-molded so that the protruded pieces of the plug body-inserting hole are embedded in a flange portion formed at a lower portion of the plug body and nozzle holes with different phases are at an upper portion of the plug body.

A tapping screw engages a member to be engaged with a base plate made of metal by tapping a burring hole formed on the base plate. The tapping screw includes a main body having a shank and a head formed at a base end of the shank. A reduced diameter shank portion extends from a fore end portion of the shank of the main body, and has a taper angle .theta. of 9.degree. to 14.degree. and a substantially rounded triangle shaped cross-section. Recesses having no thread are formed at three faces of the reduced diameter shank portion so that a circumferential width of each recess is gradually reduced toward a tip end of the reduced diameter shank portion. Each recess is formed by a steep face facing a screwing direction of the tapping screw and a gentle face oppositely facing the steep face to form a groove.

A bolt for a truss includes a main body having a head portion, and a shaft portion which extends from the head portion. The shaft portion includes a base portion with a polygonal cross-section at a head portion side of the shaft portion. A threaded portion extends from the base portion, and an annular groove is arranged between the base portion and the threaded portion. A polygonal tube having a polygonal cross-section is engaged with the shaft portion of the main body such that the polygonal tube is slideable and non-rotatable on the base portion. A stopper prevents release of the polygonal tube from the shaft portion, the stopper including a plastic ring having a peripheral surface on which plural engaging protrusions are formed, the ring being integratedly embedded in the annular groove.

Bolt for truss, wherein the bolt has shaft portions separated by a

A holder for a window glass of a vehicle which has a reduced number of parts, which can make the mounting operation simpler, thereby lowering costs, and which can prevent the window glass from having play or loosening. The holder comprises a nut and a bolt. The nut has a female screw sleeve portion which is to be inserted with a clearance into a mounting hole formed in the window glass, and a holding plate member radially outwardly extending from the sleeve portion. The bolt has a screw shaft member to be screwed into the female screw sleeve portion, and a holding plate member radially outwardly extending from the screw shaft member. In addition, a cushion layer made of a synthetic thermoplastic resin elastomer is attached to the inside surface of each holding plate member. The cushion layer is provided at its inner circumferential edge with a short sleeve portion for protecting an edge of the mounting hole of the window glass.

A holding device for use in assembling mechanical members comprises a joint head having a spherical head and a fastener formed continuous with the spherical head; and a clip having a joint cavity member formed of an elastic material, the joint cavity member having a groove portion having a cross-section corresponding in shape to an external shape of the spherical head, and receiving lip portions formed continuous with the groove portion, the receiving lip portions spreading outward, and a fastener formed continuous with the joint cavity member. The spherical head of the joint can be fitted in the groove portion to be held therein, whereby a member which is fastened to the fastener of the joint head and a member which is fastened to the fastener of the clip can be preliminarily held to each other. The invention provides the preliminarily-holding device for use in assembling mechanical members, which is capable of causing a part (e.g. a bumper of an automotive vehicle) having destortion in its formed shape to be preliminarily held onto a body (e.g. of the vehicle) having dimensional or positional errors in assembly, while absorbing deviations in the positional relationship between the part and body to be assembled.

A grommet for automatic insertion into a mounting hole in a panel by a robot including a head portion 1 having a longitudinal bore for receiving a screw through its center, a bottom portion 3 including a stepped portion 7 elastically engaging the robot arm located within the longitudinal bore; and locking claws 4 attached to the grommet which reflect during insertion of the grommet into the mounting hole and then spring snap into engagement when the locking claws 4 clear the mounting hole, such that the force required to disengage the robot arm 5 from the stepped portion 7 is less than the force required to extract the grommet from the panel, which enables the robot to easily determine whether or not the grommet is accurately inserted into the mounting hole.

Grommet and method of inserting grommet

A cover of synthetic resin is formed within a stepped recess of a nut adjacent the upper end of the internally threaded portion by injection molding. The cover includes a ring-like mounting frame positioned in the stepped recess, and a covering plate positioned inside the ring-like mounting frame and connected to it by a hinge portion of the cover. The ring-like mounting frame have an integral portion provided at the lower portion of the frame and firmly engaging a portion of the inner surface of the internally threaded portion.

Nut with cover

A plastic screw anchor having legs each formed with a recess which provides the leg with good flexibility whereby the legs can easily deform during the insertion thereof into an aperture of a supporting plate and also provides a strong grip between the screw anchor and the supporting plate. A wing integrally formed on each leg prevents the screw anchor from coming out of the aperture after having once been inserted therein.
