In a fluid dynamic bearing apparatus, an oil buffer is defined between a thrust gap and a pumping gap. The planographic printing plate precursor is characterized by the cross-linking hydrophilic layer being produced by reacting a hydrophilic high molecular compound having, on the backbone polymer thereof, a group which is able to react with a cross-linking agent, with the cross-linking agent. The system employs this complex logic per medication and generates a variety of email, phone call, SMS, MMS, voice messages, audio, visual and multimedia cues and alerts to enforce compliance. It is then checked whether a stream that is found to be playable by the playback apparatus is included in a main clip or a sub clip, and the main clip referred to by the Main Path is read together with the clip in which the corresponding audio stream is multiplexed. The grounding supports connected between the radiating member and the ground plane excellently improve the combination of the radiating member and the ground plane to prevent the antenna from inadvertently disassembling. Under this arrangement, when the light collecting unit acquires the brightness value of the targeted region, the brightness value is transmitted to the MCU and compared with a predetermined brightness value, so that a difference value is obtained and transmitted to the PWM unit; hence, the light emitting unit is controlled by the PWM unit to project a light beam with a designated intensity.
