There is provided an electromagnet control apparatus that continuously attracts crushed pieces of metals with the core of a magnetized electromagnet without immediately releasing the attracted pieces in a composite operation of a construction machine. The electromagnet control apparatus includes a control unit that controls a demagnetized state, a magnetized state, or a counter-magnetized state of an electromagnet. Until the end of a first threshold time t_(th1 )from a transition to the demagnetized state from the magnetized state, the control unit ignores a turn-on voltage for turning on first transistors (a first transistor, a fourth transistor) and turns on the first transistors after a lapse of a second threshold time that is shorter than the first threshold time. The demagnetized state and the magnetized state are repeated until the end of the first threshold time t_(th1 )from the transition to the demagnetized state.


A method of manufacturing stably a nitride fluorescent substance under more flexible reaction conditions at a low cost includes the steps of: mixing a raw material containing a complex of nitrogen element and metallic element; obtaining a raw material mixture; sintering the raw material mixture and obtaining a nitride or an oxynitride.

The present invention is to provide a method of favorably forming an organic EL device with the inverted structure by the wet process. On that account, an organic EL device includes a cathode, an electron injection layer, a light emitting layer, a hole transport layer, a hole injection layer, an anode are formed in this order on a substrate. The electron injection layer is formed by applying ink between banks and drying the ink. The ink is formed by dissolving a polymer compound having an organic phosphine oxide skeleton in an alcohol solvent. The light emitting layer is formed by applying ink between components of the bank and the drying the ink. The ink is formed by dissolving material for light emitting layer such as polyphenylene vinylene (PPV) derivative or polyfluorene derivative in a nonpolar solvent.
