Abstract: To provide a resin composition excellent in foam suppressing properties as well as foam breaking properties. A resin composition including a resin (X) excluding the copolymer (Y) described below and an ethylene·?-olefin copolymer (Y) satisfying the following requirements (y-1) and (y-2): (y-1) The solubility parameter calculated based on a D. W. Van Krevelen's estimation method is 15.5 to 16.3 (MPa)1/2; and (y-2) The weight-average molecular weight (Mw) obtained by gel permeation chromatography (GPC) is 1,500 to 30,000.

Abstract: The resin composition contains at least one resin (S) selected from the group consisting of an ethylene??-olefin copolymer (A) including a structural unit derived from an ?-olefin having 3 or more carbon atoms and satisfying the following requirements (a-1) to (a-3), and an acid-modified product (B) of the ethylene??-olefin copolymer (A): (a-1) a kinematic viscosity at 100° C. is 10 to 5,000 mm2/s, (a-2) a content rate of a structural unit derived from an ?-olefin having 3 or more carbon atoms is 60 to 85 mol %, and (a-3) a molecular weight distribution (Mw/Mn) is 2.5 or less.

Abstract: A shot processing apparatus in which a projection machine projects projection media onto a workpiece. The shot processing apparatus includes plural hanger transport devices and a control unit. The hanger transport devices are each, in a hanging state of a member on which a workpiece is set or a hanging state of a workpiece, capable of moving along a guide path inside the shot processing apparatus and capable of stopping. The hanger transport devices are also capable of providing self-identifying identification information. The control unit controls the hanger transport devices by outputting to each of the plural hanger transport devices a control signal appropriate to each of the hanger transport devices. This control is based on the identification information provided from each of the individual hanger transport devices and based on information related to each of the individual hanger transport devices stored in advance in association with the identification information.

Abstract: A shot processing apparatus is equipped with a work set jig, a hanger transport device, a projection machine, a projection positioning unit and a clamp unit. The work set jig is equipped with a base member including an upper and lower pair of cross members and a vertical member. A workpiece is settable at the base member between the upper and lower pair of cross members. The hanger transport device is, with the work set jig in a hanging state, movable along a guide path in the shot processing apparatus and is capable of stopping thereon. The projection machine projects projection media at a workpiece set at the base member inside a projection chamber which the workpiece is conveyed into. The projection positioning unit positions the work set jig at a stopping position in the projection chamber. The clamp unit fixes a workpiece between the upper and lower pair of cross members.

Abstract: The present invention has the object of providing a shot processing machine capable of constraining the spilling over and dropping of projection material to outside the projection chamber. The shot processing machine of the invention is a shot processing machine for performing surface treatment by projecting projection material onto a workpiece inside a projection chamber, comprising: a cabinet inside of which a projection chamber is formed, an opening disposed on the cabinet for loading and discharging workpieces; and a door movably attached to the cabinet, for opening and closing the opening, whereby a projection material adhesion prevention mechanism for preventing the adhesion of projection material is provided on the inside of the door.

Abstract: The present invention provides a drum for a shot blasting apparatus that uniformly treats the works to be treated by increasing the level of agitation of the works that are buried at the bottom of the drum, and, further, suppressing the traces of collisions on the works, which traces are caused by the works colliding with each other. The drum comprises a hollow middle part, a lower-half part having the shape of a truncated cone, having a closed bottom, and having a projecting part for agitating that is connected to both the lower-half part and the middle part, and that agitates the works, wherein the projecting part for agitating has at least two surfaces, one being the surface for picking-up the works and the other being the surface for having the works slide down. The present invention also provides the shot blasting apparatus using the drum.

Abstract: To provide a novel shot-blasting machine to eliminate a dead space for a cover that shuts an opening for feeding and taking out works and to open and close the cover by moving a rotary drum around an axis. The machine has a cabinet 11, a rotary drum 13 having holes, and a centrifugal shooting machine 15. The rotary drum 13 moves, within the cabinet 11, around an axis through the positions for feeding, processing, and taking out the works. The cabinet 11 comprises a cover 51 for shutting an opening 11b for feeding and taking out the works. It has a wall 59 for sealing the side of the opening 11b. The cover 51 is integrated with the rotary drum 13 to move around the axis. It has walls 51a, 51b, 51d that fit the wall 59 for sealing. Lip seals 61, 63 seal the gap between the walls 51a, 51b, 51d of the cover 51 and the wall 59 for sealing.
