The measured value of a rubber temperature parameter that is related to the temperature of a rubber material to be kneaded by a mixing machineand measured values of correlation parameters that have a correlation with a change in the value of the rubber temperature parameter are acquired. The measured values are assigned to an operational control parameter-calculation model equation, which is modified from a rubber temperature parameter-calculation model equation including operational control parameters and the correlation parameters, and a constant and coefficients of the operational control parameters and the correlation parameters are calculated using a machine learning algorithm. A predetermined operational control parameter, which is required in a case in which the rubber temperature parameter is controlled to a predetermined value, is calculated using an operational control parameter-calculation equation that is specified by the coefficients and the constant calculated using the machine learning algorithm.

A charging and discharging control device includes a pantograph point voltage detection unit configured to detect a pantograph point voltage of a vehicle, a charging and discharging control unit configured to charge a power storage device provided in a vehicle when the pantograph point voltage is greater than or equal to a charging voltage threshold value and discharge the power storage device when the pantograph point voltage is less than a discharging voltage threshold value, a load determination unit configured to determine whether an absolute value of load power for the vehicle is less than a load power threshold value, and a charging and discharging control change unit configured to reduce any one or more of the charging voltage threshold value, the discharging voltage threshold value, and charging/discharging impedance when the absolute value of the load power is less than the load power threshold value.

Mold heating device and tire vulcanizer

What is provided is a tire vulcanizer, in which the stress force during engagement of the teeth can be reduced and teeth damage can be suppressed, allowing down-sizing, light-weighting, and simplifying at the same time. It includes: an upper mold attaching part () to which an upper mold is attached; a lower mold attachment part to which a lower mold pressed on the upper mold is attached; a supporting part () that supports the upper mold attaching part () and the lower mold attaching part; a fixed side rack () having first teeth () arranged in a height direction and provided to the supporting part (); a movable-side rack () having second teeth () engaging with the first teeth and provided to the upper mold attaching part (); and a tilting restriction part () restricting tilt of the movable-side rack () derived from the height direction.

Tire vulcanizer

To provide a tire vulcanizer capable of solving problems of an electrical heating platen, which relate to the deformation at the time of tire vulcanization and to the replacement of the platen. The tire vulcanizer vulcanizes and molds a green tire placed in an outer mold by heating the green tire from the outer side and the inner side of the green tire, and is featured by including an electric platen () which is arranged to be in contact with each of the upper and lower sides of a container with the green tire placed therein, or to be embedded in each of the upper and lower portions of the container, so as to heat the green tire from the outside of the outer mold at the time of vulcanization, and which is formed into a doughnut-like disc shape and divided into a plurality of sections in the circumferential direction of the platen ().

In a vulcanizing system of the present invention, a temperature booster and a pressure booster are provided on a steam supply path connecting vulcanizers that belong to groups and a boiler allocated to the groups. The temperature booster and the pressure booster are sequentially arranged from an upstream side, a second branch supply path for supplying the steam to a mold between the temperature booster and the pressure booster is branched from the steam supply path. The second branch supply path is preferably in a form of allowing the steam temperature-boosted by the temperature booster to be supplied to the mold by bypassing the pressure booster.
