Abstract: This battery unit is a battery unit including a battery pack that houses a battery cell, and a water-cooling medium flow path formed outside a bottom surface of the battery pack, in which the water-cooling medium flow path is made of a Zn-based plated steel sheet, an inorganic film or a resin film is formed as a chemical conversion coating film on a surface of the Zn-based plated steel sheet, and the inorganic film contains a Si-based component or a Zr-based component as a main component.

Abstract: A first base-side pulley is disposed at the base portion of a first arm portion; a first distal-side pulley is disposed at the distal portion of the first arm portion; a second base-side pulley is disposed at the base portion of a second arm portion; a second distal-side pulley is disposed at the distal portion of the second arm portion; the first base-side pulley is fixed to the support base; the chuck is fixed to the second distal-side pulley; the first distal-side pulley and the second base-side pulley are connected to each other via a connection shaft; the first base-side pulley and the first distal-side pulley are connected to each other via a first rotation transmission section; and the second base side pulley and the second distal-side pulley are connected to each other via a second rotation transmission section. Thus, an articulated robot arm having first and second arm portions is constructed.

Abstract: A robot for a production machine including a rotation drive unit disposed on a support base; a first arm having a proximal end portion fixed to a rotary shaft of the rotation drive unit; a first proximal-side pulley disposed coaxially with the rotary shaft and fixed to the support base; a second proximal-side pulley fixed to a distal end portion of the first arm; an intermediate shaft rotatably supported on the distal end portion of the first arm and penetrating a center portion of the second proximal-side pulley; a first distal-side pulley provided integrally with the intermediate shaft; a first rotation transmission section for drivingly connecting the first distal-side pulley and the first proximal-side pulley; a second arm having a proximal end portion fixed to the intermediate shaft; a distal-side shaft rotatably supported on a distal end portion of the second arm; a second distal-side pulley provided integrally with the distal-side shaft; a second rotation transmission section for drivingly connecting t

Abstract: A robot for a production machine includes a parallel link mechanism including opposed first and second shorter-side links and opposed first and second longer-side links which form a parallelogram. A chuck is supported on the first shorter-side link. A guide rail is fixed to a base arm in order to movably support the second shorter-side link. The base end of a drive link is rotatably attached to the base arm, and the distal end of the drive link is attached to an intermediate portion of one of the first and second longer-side links. A drive mechanism is provided in order to rotate the base end of the drive link. This structure simplifies the mechanical system and the control system, reduces a space required in the vertical direction, and increases operation speed such as product removal speed.

Abstract: A tube container molding apparatus in which a cylindrical tube is inserted into a split mold in its closed state so that the end section of the tube comes into contact with a cavity face of the split mold. A core is then advanced to fit into the tube from its rear end, and finally a resin melt is introduced into the cavity formed by the cavity face of the split mold and the end face of the core.When the resin melt is injected into the cavity, a tube holding piece pushes the tube against the core to prevent the tube from being drawn out of the cavity.Midway during the advance of the core into the tube, the tube is held by the tube holding piece and the further advance of the tube is made together with the core. Thus, the forward end section of the tube is bent inward to a prescribed width.
