摘要： An apparatus for controlling a synchronous generator having a converter. A voltage detector detects a terminal voltage of a stator of the synchronous generator. A current detector detects a current flowing through the stator. A rotor position estimating part estimates a rotor position of the synchronous generator from the detected voltage and current. An active power detector detects a active power of the synchronous generator. A reactive power detector detects a reactive power of the synchronous generator or a terminal voltage detector detects an effective value of a terminal voltage of the stator. An active power controller adjusts a q-axis current command to control the active power, and a reactive power controller or terminal voltage controller adjusts a d-axis current command to control the reactive power or terminal voltage.

摘要： When molded plates of aluminum nitride obtained by molding a ceramic powder formed preponderantly of aluminum nitride powder are superposed on a support base with a ceramic powder interposed between the support base and the superposed plates and between the superposed plates and are fired in a non-oxidative atmosphere, the sintered plates consequently produced are prevented from sustaining crack or fracture.When warped and undulated sintered plates of aluminum nitride are superposed on a support base with a ceramic powder interposed between the support base and the superposed plates and between the superposed plates and are heated in a non-oxidative atmosphere, the heated plates are relieved of warp and undulation.The sintered plates of aluminum nitride are enabled to acquire improved adhesiveness to a metal film or foil when they are subjected to a heat treatment adapted to reduce the surface roughness to or below 10 .mu.m (Rmax).
