Title: Flow velocity measuring device
Inventor: KAWASAKI OSAMU
IPC: G01F1/66
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a flow velocity measuring device capable of making flow velocity measurements at all times with high measuring accuracy, by avoiding the formation of vortices in a fluid on the front surfaces of ultrasonic transceivers and pressure drop due to the presence of recesses formed by the installation of the ultrasonic transceivers in a wall surface constituting a flow passage. SOLUTION: Recesses formed by the installation of ultrasonic transceivers 1, 2 in a wall surface 3 constituting a flow passage are filled with fillers 3, 4 to reduce the recesses in the flow passage. Therefore, a fluid is allowed to flow smoothly in the flow passage in the direction of the arrow, preventing the formation of vortices on the front surfaces of the ultrasonic transceivers 1, 2 and preventing pressure drop due to flow.

Title: Detecting system for synchronization of carrier wave
Inventor: SUZUKI EIJI
IPC: H04L27/00
Filed: 1984-12-06
Abstract: PURPOSE:To attain cost reduction with the titled detecting system by detecting the synchronous state of the carrier waves by making use of a fact that the existing probability of the signal points within a specific area differs between a synchronous mode and an asynchronous mode. CONSTITUTION:Discrimination circuits 1-3 and 13-15 are used to observe a specific area. Thus the output of a 50% mark factor is obtained from an EX-OR circuit 18 in a synchronous mode of carrier waves. While the output having a deviated mark factor compared with 50% is obtained from the circuit 18 in an asynchronous mode of carrier waves. These outputs are integrated by an integration circuit 19 to obtain the voltage V1 with the former output and the voltage V2 with the latter output respectively. An alarm can be delivered to the outside with said voltages V1 and V2 and therefore no discrimination is needed for detection of a synchronous state.
