In a certain brake control apparatus, a valve main body of a hydraulic control valve and a coil unit are separately formed, are assembled with each other, and are mounted on an actuator block. The server computer runs an application in response to the requests and constructs output information at the server computer in a format usable by the browser program, based on results generated from the application. Certain pseudobase benzocphenanthridines provided herein act as prodrugs, targeting the parent benzocphenanthridinium alkaloid to hydrophilic or hydrophobic regions in the body. This particular means for assembly allows the reflector cup and circuit board to cooperate to retain the LED package, provide electrical and control connections, provide integral heat sink capacity and includes an integrated reflector cup. Metal layers are printed to form the electrode layers of the piezoelectric member and the electrical contact portions of the device. A controller 21 detects the power factor state of a generator when a normal operation mode is switched to a low-voltage control mode and sets a condition for switching from the low-voltage control mode to the normal operation mode depending on the detected power factor state.
