Title: Ultrasonic type fluid measuring device
Inventor: UMEKAGE YASUHIRO
IPC: G01F1/66
Filed: 2004-02-24
Abstract: An ultrasonic type fluid measuring device capable of high precision fluid measurement. A fluid passageway is intermediately provided with a measuring section (1) formed with a plurality of divisional flow channels (3) through partition plates (2). Ultrasonic waves are sent into a fluid flowing through the divisional flow channels (3) through at least a pair of ultrasonic wave transmission/reception device, and ultrasonic waves are received after passing through the fluid. And on the basis of the propagation rate of the ultrasonic waves, an arithmetic-logic unit computes at least either the flow rate or the flow quantity of the fluid. Further, the measuring section (1) is provided with run-up flow channels (5, 6) leading to the divisional flow channels (3) to pre-regulate the flow of the fluid.

Title: Disc drive apparatus, and method for recognizing cd and dvd
Inventor: YAK AIK S
IPC: G11B19/12
Filed: 2004-03-26
Abstract: A method is described for measuring the thickness of an optical disc and determining whether the disc is a CD or a DVD. The optical lens is caused to move towards the disc with a substantially constant speed, with the optical beam switched on, and the focal error signal (FES) is analyzed. By timing the S-shaped curve (62), the actual value of said speed is determined. By timing different reflections (72,73) from the disc, taking into account the measured speed, the thickness of the disc is determined. An important advantage is that the outcome of the thickness measurement is substantially independent from the actual value of said speed, and thus independent from the actual sensitivity of the actuator.
