Title: Coriolis-type mass flowmeter
Inventor: OYA AKIRA
IPC: G01F1/84
Filed: 1994-05-18
Abstract: PURPOSE:To enable the mass flow rate of a fluid for measurement to be measured efficiently by using a strain sensor for detecting torque produced by the torsion of a loop portion due to displacement. CONSTITUTION:Each of the straight tube portions 12A, 12B of a measuring tube 12 has one end secured to a fixed end 10, 11, and a loop portion 12E extending in the direction of X axis from curved portions 12C, 12D is integrated with the measuring tube. An exciter 13 disposed at the mid point of the loop portion 12E causes simple harmonic motion of the loop portion 12E in the direction of Z axis. A cylindrical torque tube 14 through which no fluid Q to be measured flows is held in place between the curved portions 12C, 12D. When the fluid Q flows through the tube 12, opposite rotational forces are applied to the upstream and downstream sides of the tube portion 12E, so the tube 14 is twisted and a strain sensor mounted in the tube 14 detects torque (shearing strain). Since this shearing strain is proportional to the Coriolis force, i.e., mass flow through the tube 14, the mass flow rate of the fluid Q can be determined efficiently through the detection of the shearing strain using the strain sensor.

Title: Cutoff controller for variable displacement type hydraulic pump
Inventor: AKIYAMA TERUO
IPC: F04B49/00
Filed: 1985-05-17
Abstract: PURPOSE:To make a structure simple enough as well as to dispense with the necessity of a demand for sizing accuracy, by installing a device which electrically detects the discharge pressure and displacement of a hydraulic pump, while performing a job of cutoff control in an electric manner. CONSTITUTION:When load is imposed on a load element 10 and discharge pressure in a variable pump 4 goes up, a pressure sensor 16, for example, accord ing to a characteristic shown in illustration, outputs a signal EP in proportion to the pump discharge pressure P. This signal EP is inputted into a multiplier 19 inside a controller 18. The multiplier 19 outputs an output signal E0=E01 at a time when the signal EP is EP<EP0, but when it is EP>=EP0, it outputs an output signal E0 inversely proportional to EP. The signal EP0 corresponds to cutoff starting pump discharge pressure. The output isgnal E0 is calculated by an adder 21 together with a discplacement signal Ey out of a displacement sensor 14 whereby a deviation signal E0-Ey is outputted.

Title: Amplitude detecting circuit
Inventor: KUMANO MASAHIRO
IPC: G01R19/04
Filed: 1985-05-17
Abstract: PURPOSE:To improve comparison precision and to process a small input signal accurately by fixing the minimum level of the input signal to transmit faithfully the input signal waveform hereafter and making the input signal amplitude itself of the comparison object of a differential amplifier in a succeeding stage. CONSTITUTION:When a sine wave is inputted to an external input terminal 13 and the potential of an input terminal 12 tries to be lower than V1-VBE20 by the input signal, an NPN transistor TR 20 is made conductive quickly, and the input impedance in the terminal 12 is reduced to charge an external capacitor C1, and the minimum level of the input signal is clamped at V1-VBE20. Though the level of the input signal is increased from the minimum level after the completion of this clamping, the TR 20 goes to the turning-on state because the potential of the terminal 12 is increased from V1-VBE20, and the input impedance of the terminal 12 is raised, and the capacitor C1 is discharged only with the base current of a TR 2, and the minimum level of the input signal is fixed at V1-VBE20 in the waveform of the terminal 12. (V1 is the base potential of the TR 20, and VBE20 is the potential difference between the base and the emitter of the TR 20).

Abstract: PURPOSE:To produce cylindrical compact without any traverse crack by closing both ends of rubber cylindrical body, in which powdery raw material is packed, by covering bodies preventing mutual approach of the covering by an outer cylindrical member and working hydraulic pressure to the rubber cylindrical body through liquid passing-through holes arranged in the outer cylindrical member. CONSTITUTION:The Al (alloy) powdery raw material 4 or compacting is packed in the rubber cylindrical body 6 and both end opening parts of the cylindrical body 6 are closed water-tightly by the rigid covering bodies 8, 10. Outer flanges 8a, 10a are integrately formed on the covering bodies 8, 10 and the outer cylindrical member 14 is inserted between the outer flanges to prevent shrinkage of the cylindrical body 6 toward axial direction. The outer cylindrical member 14 is constituted by half dividing bodies 14a, 14b and suitable number of the liquid passing-through holes are arranged at each body 14a. 14b. High pressure liquid is invaded through these liquid passing-through holes, and the prescribed pressurizing force is worked to the outer circumferential face of the cylindrical body 4 to compress the law material 4 toward diameter detection at the prescribed compressing force. Then, the mutual approach of the covering bodies 8, 10 are prevented by the outer cylindrical member 14 and displacement of the. rubber cylindrical body 6 toward axial direction is prevented. By this method, the traverse crack in the powder compact is prevented, and treatment of the compact is facilitated.
