Title: Sound field displaying device
Inventor: KOMIYAMA SETSU
IPC: H04R5/027
Filed: 1987-03-20
Abstract: PURPOSE:To make the state of the wave front of a sound field observable in real time, by tow- or three-dimentionally measuring the acoustic pressure and the speeds of particles at a listening location and performing prescribed calculation on the measured results. CONSTITUTION:Signals proportional to the acoustic pressure are obtained by using a non-directional pressure type microphone M2 and signals proportional to the speeds of particles in both (x) and (y) directions are obtained by means of both directional speed type microphones M1 and M3. These signals are led to BPFs 2-1-2-N, 4-1-4-N, and 6-1-6-N having widths of 1/3 octave and separated into each frequency component. At arithmetic sections 8-1-8-N and 10-1-10-N products of the acoustic pressure and particle speeds in both (x) and (y) directions are integrated for a time T. As a result, direction of the particle speed having the same phase as the acoustic pressure (function of time) has is found as a vector component. Mulitplexers (MPX) 12 and 14 output either one of the vector components. At a displaying section 16, the above-mentioned vector component is inputted as the longitudinal and transverse axis signals and displayed as an (x) and (y) components. Therefore, the home position of an acoustic image can be displayed directly from an acoustic field and, especially, the front-rear judgement of an acoustic image can be performed.

Title: Signal transmission system
Inventor: TATEZUKI KUNIHARU
IPC: H04B7/15
Filed: 1986-03-22
Abstract: PURPOSE:To make a timer circuit, which sets the operation time of a repeating transmission means, unnecessary by setting the call signal transmission time of a transmitter to a value slightly longer than the sum of the interval of interrupted reception of a repeater and that of a receiver. CONSTITUTION:A transmission time t1 of the call signal in a transmitter 1 is made slightly longer than the sum of an interval t2 of interrupted reception of a repeater 3 and an interval t3 of that of a receiver 2. Even if the call signal is transmitted just after the end of the interrupted reception period of the repeater 3 and a transmission time t4 of the repeated call signal transmitted from the repeater 3 is t1-t2, the repeated call signal is detected surely by the receiver 2 because the transmission time t4 is slightly longer than the interval of interrupted reception of the receiver 2.

Abstract: PURPOSE:To improve the accuracy of travel control by rotating picked-up picture so that a traveling direction can be a Y-axis direction according to a skid angle. CONSTITUTION:When converting the picked-up picture to a picture observed in the traveling direction of a vehicle according to a lateral sliding angle betaof the vehicle, with a point P as a center, the picked-up picture is rotated only for the angle beta so that the real traveling direction [vector(v) direction] of the vehicle 11 can be the Y-axis direction on an X-Y coordinate. According to the picture to which the rotation processing is executed corresponding to the angle beta, the travel enable area is recognized on the X-Y coordinate and the target route is set in the area. Then, a control target amount is calculated to follow up the target route and the travel control of the vehicle is executed without being affected the lateral sliding angle beta at all. Thus, the accuracy of the travel control can be improved.

Title: Sensitized fluxmeter
Inventor: NAKANE HIDEAKI
IPC: H01L39/22
Filed: 1990-03-15
Abstract: PURPOSE: To improve the sensitivity and to lower the noise by comprising an input coil as one continuous loop for applying input magnetic flux to two SQUIDs formed of a superconducting loop reversely. CONSTITUTION: Input coils 5, 5' are coupled in series as one loop, and a terminal 6 is taken out from its mid-point. When the signal captured from the terminal 6 by a pickup coil is input, the signals are split n parallel with the coils 5, 5' and introduced. Since the coils are wound reversely, the directions of the magnetic fluxes crossing with the DC-SQUIDS 1, 1' become reverse. The output signal of the fluxmeter is output from the terminals 7, 7' at the series voltage of the SQUIDS 1, 1'. Bias current is applied to the SQUIDS 1, 1' from DC power sources 8, 8' via terminals 9, 9', 9". The direction of the bias current is applied so as to generate the voltages of opposite polarities. Thus, the magnetic flux transmitting function between the coils 5 and 5' has the effect of removing noise magnetic flux externally applied to the SQUIDS 1, 1'.
