Abstract: An optical pickup having a blade including a first blade in which an objective lens is mounted and which is made of a reinforced plastics material, and a second blade in which driving coils are mounted and which is made of a magnesium alloy material. Since the first blade has a low thermal conductivity coefficient, the heat generated in the coils is prevented from being transferred to the objective lens, whereas the second blade having a high thermal conductivity coefficient radiates the heat generated by the coils to the outside. Thus, the heat distortion of the objective lens can be suppressed, and damages to the coils or rigidity reduction of the blade can be avoided.

The first and second piezoelectric sensors are selectively arranged at two points whereat stress distribution of the noise component due to disturbance vibration and stress distribution of a signal component due to vortex dynamic lift are different from each other.

Abstract: A flow metering apparatus is disclosed which includes a dust in which a fluid to be measured flows, a pillar-shaped vortex generator inserted into the duct, and a force detector fixed firmly to the vortex generator substantially in an integrated manner, and capable of directly detecting an alternating force applied to the vortex generator due to Karman's vortex generated by the vortex generator, and converting the alternating force into an electric output signal.

Abstract: A vortex flow meter produces Karman's vortices in a fluid to be measured and a piezoelectric sensor develops a vortex signal therefrom which is proportional to the flow velocity of the fluid. The output signal of the sensor is applied to a charge amplifier and a low pass filter coupled thereto which functions to a predetermined signal amplitude for limiting low and high frequency noise and stabilizing the gain of the system within the vortex frequency measuring range. The output signal is converted by a logic circuit to a pulse signal of vortex frequency and then converted to a DC signal for transmission to an indicator or a receiver.
