Title: Switching power supply circuit
Inventor: HAYAZAKI KIYONOBU
IPC: H02M3/28
Filed: 1990-06-15
Abstract: PURPOSE:To get a micro current limiting circuit suitable for a high frequency switching power source by using, as current detecting voltage, the ON voltage of a main switching FET for the current limiting circuit of a switching power supply. CONSTITUTION:When the output wave form VGS of the pulse width output terminal DRV of a pulse width control circuit 3 exceeds the gate threshold of a main switching FET 4, the main switching FET 4 is turned on, and starts letting a switching current ID flow. When the voltage VGS rises further and reaches the gate threshold of the FET 5 for current detection, the FET 5 for current detection is turned on. In case that the load current is large, the pulse width control circuit 3 breaks the output of the DRV terminal, and cuts off the main switching FET 4, and limits the output current of the switching power supply. Though the FET 5 for current detection requires the breakdown strength equivalent to the main switching FET 4, there is necessity of letting only a little current flow to the OC terminal of the pulse width control circuit 3, so a small-sized FET can be used, and the current detection circuit becomes a small-sized one.

Title: Acoustic circulating water tank measuring device
Inventor: SATO RYUICHI
IPC: G01M10/00
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To provide an acoustic circulating water tank measuring device for measuring sound generated from various test pieces place in water current of a circulating water tank in high sensitivity by separating the sound from background noise and which can analyze position of sound source. SOLUTION: Sound wave generated from a test piece such as a propeller is transmitted to a measuring cylinder 30 and reaches a plurality of hydrophones 43 disposed in plane around the measuring cylinder 30. As time of the sound wave from the test piece reaches the respective hydrophones 43 differs, directivity may be provided by superposing signals from the respective hydrophones 43 taking the difference as phase difference. Thereby, sound source of the test piece is obtained since the hydrophones 43 are disposed around the measuring cylinder 30. Since the sound wave transmitted to background of the respective hydrophones 43 is absorbed into sound absorption material 40, reflection wave at noise absorption troughs 37-39 does not reach the hydrophones and high S/N ratio is obtained.
