Title: Surface corona detector
Inventor: HAGA KOUJI
IPC: G01N29/00
Filed: 1983-05-26
Abstract: PURPOSE:To make it possible to certainly view with eyesight the surface corona of a target, by connecting a repeating pulse generator for generating a repeating pulse having frequency matched with that of surface corona and a frequency discriminator to an ultrasonic sensor while displaying a lamp corresponding to the magnitude of frequencies of both of them. CONSTITUTION:The frequency of the output pulse of a repeating pulse generator 3 is preset so as to be almost equal to the frequency of surface corona of the target. A wave height discriminator 4 compares the voltage levels of the output pulse of an amplifier 2 and the output pulse of the pulse generator 3 and the repeating pulse is passed only when the output pulse voltage of the amplifier is higher than that of the pulse generator 3. The magnitude of the ultrasonic signal caught by an ultrasonic sensor 1 can be known by combining the wave height discriminator 4 and the variable amplifier 2. A high frequency detector 61 is operated when the output pulse number of the crest discriminator 4 is high as compared with the frequency of the pulse generator 3 to generate a pulse. In a reverse case, a flow frequency detector 62 is operated. By this mechanism, the generation of surface corona of the target can be visually confirmed.

Title: Acoustic positioning device and synchronous positioning system
Inventor: TAKAHASHI HIDEYUKI
IPC: G01S5/18
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To enable accurate acoustic positioning without interference even when a plurality of the same positioning devices are used int the same or proximate sea areas by simultaneously transmitting interrogation signals on the basis of seconds by time signals from a GPS receiver. SOLUTION: A GPS receiver 13 receives radio waves from GPS satellites by a GPS antenna 14 to obtain location information, outputs accurate one-second signals, and supplies them to a control computing part 1 via an interrupt circuit 12. The control computing part 1 creates transmission timing signals on the basis of the accurate second signals and supplies them to a transmission control circuit 2. Therefore, as a plurality of ships, the same devices onboard, on the same sea surface can simultaneously transmit the interrogation signals at transmission timing in synchronism with the second signals, it is possible to prevent the mixing of signals from other ships and to perform accurate acoustic positioning without error measurements. At this point, the minimum measurement distance becomes an official slant range.

Title: Bias controlling circuit
Inventor: NAKAYAMA KAZUAKI
IPC: H03F3/30
Filed: 1981-06-17
Abstract: PURPOSE: To improve the temperature characteristics through no adjustment of a bias current adjusting circuit, by controlling a DC bias current so that a no error can be caused in comparison with a reference value.  
     CONSTITUTION: A signal current flowing to an output transistor (TR)Q 3  is detected by a linear detection circuit 4. This detection output becomes an inverting input to an operational amplifier A 2 . The operational amplifier A 2  outputs a differential voltage between a reference voltage E 0  and a detected output as an error voltage. A variable bias circuit 2 can control a base bias of TRs Q 1  and Q 2  in accordance with the conductive state of a TRQ 9 . Thus, an idle current of an output TR can be controlled by applying the error voltage to the base of the TRQ 9 . Since the idle current can be controlled accurately with a reference voltage E 0 , the bias current can be constant immediately after the application of power supply.
