Abstract: Vehicle allocation system includes an information provision apparatus, a first apparatus: control apparatus, and a user's second apparatus: user terminal apparatus. Processor of the information provision apparatus calculates a first driving plan for a vehicle in response to request information. When a second driving plan different from the first driving plan is calculated based on detection information acquired from the vehicle, the processor determines the cause of a change in the driving plan on the basis of the detection information. The processor transmits cause information including the cause to the user terminal apparatus. The user terminal apparatus presents the cause information on a display.

Abstract: A plastic resin cutting apparatus for cutting a plastic extruded from an extrusion opening provided in a flat surface of an extrusion block. The apparatus comprises a rotating shaft disposed substantially perpendicular to the surface of the extrusion block with its front end positioned opposite to said surface; a drive mechanism for rotating the rotating shaft; and a cutting tool interposed between the surface of the extrusion block and the front end of the rotating shaft and having formed at its front surface facing the surface of the extrusion block at least one cutting blade having a flat cutting edge. At least the front end portion of the rotating shaft is urged resiliently toward the surface of said extrusion block by the action of an elastic member such as a spring. The connection of the cutting tool to the shaft is a universal connection.

Abstract: A noise-compensating circuit for an electromagnetic flowmeter in which the fluid to be metered is conducted through a flow tube having a pair of diametrically-opposed electrodes mounted thereon, the fluid intercepting an electro-magnetic field whereby a voltage is induced in the fluid which is transferred to the electrodes to produce a flow signal that is a function of flow rate. Noise resulting from asymmetry in the magnetic field as well as noise arising from the signal leads is eliminated by means including a loop coil symmetrically disposed with respect to the transverse axis passing through the electrodes, the loop coil being so connected that the error current induced therein acts to cancel out the noise components in the flow signal.

Abstract: An electromagnetic flowmeter in which the fluid to be metered is conducted through a flow tube in which it intercepts a magnetic field, the voltage induced in the fluid being transferred to electrodes disposed at diametrically opposed points on the tube. In phase noise arising from asymmetry in the main magnetic fluxes as well as noise resulting from leakage magnetic fluxes are both compensated for by a unitary compensation system.

Abstract: A magnetic flowmeter wherein liquid to be metered is conducted through a flow tube to intersect a transverse magnetic field produced by an electromagnet, the voltage induced in the fluid being transferred to a pair of electrodes mounted at diametrically opposed positions on the tube. The electromagnet is excited by DC power which is applied thereto periodically, this being effected by means of a switch interposed between the electromagnet and the DC power source. When DC excitation is cut off by the switch, the output voltage of the flowmeter is fed to a first hold circuit, whereas during the excitation period, both the flow signal and zero voltage are fed to a second hold circuit. The outputs from both hold circuits are fed to an amplifier whereby the held zero signal is subtracted from the total voltage of flow signal and zero voltage in order to eliminate zero error due to polarization.
