Described is a technique for distributing information about one or more groups of objects in a plurality of nodes. A shielding object is provided between the position detector and an oil scattering source of a mechanical section of the injection molding machine. The heat-conducting element comprises: an adjacent section which is adjacent to a heat-generating element or the control device so that heat can be conducted; and a connected section that is connected to the adjacent housing so that heat can be conducted. Then the randomization is reversed. The user qualifications may also be established within the framework of a remote access server that is accessed by a user through a downloadable automatic dialer having code containing a unique identifier relating to a merchant, product or service.
