Title: Two-line vortex flowmeter
Inventor: ODOHIRA TETSU
IPC: G01F1/32
Filed: 1991-05-30
Abstract: PURPOSE:To arbitrarily adjust noise with a communication device without visiting a site by outputting vortex flow signals via a differential mutual conductance convertor and controlling the conversion gain of a mutual conductance circuit with the communication device. CONSTITUTION:A pair of detected vortex flow signals are inputted to a differential mutual conductance convertor 24, and the mutual conductance of individual output currents to one vortex flow signal is outputted to an arithmetic section 28 after controlling the bias voltage of a constant current source. A pulse width convertor 27 serves for conversion to a pulse width signal PWM corresponding to selected pulse width data, but a bias power supply smoothly rectifies the signal PWM and outputs it as bias voltage. In this way, noise included in a pair of vortex flow signals is balanced through communication by using digital signals transmitted from the outside while monitoring a current signal or corresponding signals.

Title: Sliding contact material
Inventor: FUJISHIMA SUSUMU
IPC: C22C5/10
Filed: 1984-06-21
Abstract: PURPOSE:To obtain the titled material having low and stable contact resistance by adding prescribed percentages of C, Sb and one or more among Si, B, Ge to Ag so as to control the stickiness of an Ag-Cd alloy and to improve the wear resistance. CONSTITUTION:A sliding contact material is obtd. by adding 0.5-15wt% Cd, 1-7wt% Sb and 0.5-5wt% one or more among Si, Bi Ge and Ga to Ag. In the material, 0.01-0.5wt% Fe group element may be substituted for part of said added elements. Since the sliding contact material is hardly stuck and has superior wear resistance, when the contact chips 1a of a commutator 1 for a small- sized motor are made of the sliding contact material, the contact chips 1a produce very little dust due to wear during sliding along brush contacts 3. No noise is generated and a beneficial effect such as low and stable contact resistance is shown.
