Abstract: A vehicle electric battery controlling apparatus is applied to a vehicle including an on-board charger to charge a battery in the vehicle with power supplied from an external power source, a heater to warm the battery, and a DC-DC converter to reduce the voltage of power from the battery and then supply the battery power to the heater. The vehicle electric battery controlling apparatus includes a DC-DC converter controller to drive the DC-DC converter to supply the battery power to the heater before the charge of the battery by the on-board charger, and an on-board charger controller to drive the on-board charger such that the power source for the heater is gradually shifted from the battery to the external power source, after the DC-DC converter is driven.

Abstract: A solidification method of radioactive waste is provided, including kneading a binder and an inorganic adsorbent to obtain a kneaded object, the in organic adsorbent included radionuclides; extruding the kneaded object to obtain an extruded material object; cutting the extruded material object to obtain at least one extruded material block; and firing the at least one extruded material block to solidify the at least one extruded material block.

Abstract: A control unit for a vehicle, which comprises an engine, a driving motor, an engaging/disengaging device, and a voltage raising device, includes a switching control unit and a voltage raising control unit controlling the voltage raising device. The switching control unit switches between a first driving mode in which the vehicle is driven by a driving force of the driving motor with the engaging/disengaging device released and a second driving mode in which the vehicle is driven by the driving force of the engine with the engaging/disengaging device engaged. In a case where a driving mode is switched from the first driving mode to the second driving mode, the switching control unit starts an engagement of the engaging/disengaging device and switches the driving mode to the second driving mode, after the voltage raising control unit starts the voltage raising control in the first driving mode.
