Title: Electromagnetic flowmeter
Inventor: HASHIMOTO TAKESHI
IPC: G01F1/58
Filed: 1987-12-16
Abstract: PURPOSE:To improve detecting accuracy, by making the length of an exciting coil in the width direction of a waterway larger than the width of the waterway. CONSTITUTION:An exciting coil 2, which generates a magnetic field in the vertical direction, is attached at the upper part of an open waterway 1 having a rectangular cross section. The length of a coil side 2b in the flowing direction of flowing water is made approximately equal to a waterway width D of the open waterway 1. The length of a coil 2a in the width direction of the waterway is made larger than the waterway width D, by, e.g., 1.5 times. When a magnetic field is generated with the coil 2, the distribution of the vertical component of the generated magnetic field is intense in the vicinity of the coil in the flowing direction, and the change in distribution becomes large. The distribution at the central part is approximately homogeneous. The distribution is intense at the outside of the open waterway 1 in the width direction of the waterway, and the change is large. The distribution becomes approximately homogeneous at the inside of the open waterway 1. Therefore, electrodes 3 and 4 are positioned in the approximately homogeneous distribution of the magnetic field in the longitudinal and lateral directions. The vertical magnetic field in the vicinities of the electrodes does not have the intense value, which is largely changed. Therefore, even if the flow speed is fluctuated, detection errors becomes less, and the measuring accuracy is improved.

Title: Speech current supply circuit
Inventor: AYANO MITSUTOSHI
IPC: H04M19/00
Filed: 1989-12-07
Abstract: PURPOSE:To reduce heat dissipation of a speech current supply circuit and to eliminate noise superimposed onto a DC current by not supplying directly a DC current to an electronic circuit but supplying the current via a noiseless DC voltage generating circuit. CONSTITUTION:A noiseless DC voltage generating circuit 3 receives a DC voltage from a DC power supply VB and an AC noise voltage included in the DC power supply VB is connected to a filter circuit comprising of a series circuit of resistors R2D, R3D via a resistor R1D and a capacitor CD connected in parallel with the series circuit and is led to the ground. Thus, only the DC voltage without noise is inputted to operational amplifiers OPD, OPE. Since the operational amplifiers OPD, OPE act like amplifiers whose amplification factor is the unity, the same DC voltage as the input voltage is fed to resistors RED, R2A of an electronic circuit 1a. Thus, a DC current without noise to the terminal equipment is sent. Moreover, since the speech current is decreased, the heat dissipation in the speech current supply circuit is reduced.
