Title: Heat type mass flow meter
Inventor: KATOGI HIROYUKI
IPC: G01F1/68
Filed: 1990-11-14
Abstract: PURPOSE:To perform high-precise measurement through simple constitution by providing a voltage proportional to a velocity of flow in a way that a multifunction computing circuit and voltage converting circuit are located in a negative feedback circuit for keeping a tempera ture difference between temperature sensitive elements on the upper and downstream side of a heat type mass flow meter at a constant value. CONSTITUTION:Heat sensitive resistance wire sensors S1 and S2 are located on the upper stream and the downstream side of a heat conductive flow pipe with a distance therebetween being long enough to allow prevention of the occurrence of heat interference with each other. Outputs from the sensors S1 and S2 through a bridge circuit containing the sensors S1 and S2 are compared with each other by a comparing amplifier 1, and from a comparing result, a velocity of flow is detected. Feedback control is made on the bridge circuit so that the temperatures of the sensors S1 and S2 are adjusted to a constant value. A multifunction computing circuit 2 and a pressure converting circuit 3 are arranged to a feedback circuit, and perform computation according to a relation formula between the output voltage of a heat type flow meter and a flow rate or a velocity of flow. Feedback of an a-constant, m 1, and an output E1 based on a relation E0=aE1<m> between outputs E1 and E2 to the bridge circuit is effected. This constitution provides a voltage always proportional to a velocity of flow based on a sensor output of the n-th power characteristics of a flow rate and measures a high-precise flow rate through simple constitution.

IPC: H03B5/12
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To realize a voltage controlled oscillator with less deterioration in its oscillating characteristics when a low control voltage is applied to the voltage controlled oscillator. SOLUTION: In the voltage controlled oscillator whose oscillated frequency is changed by applying a positive control voltage to a cathode side of a varactor diode to change the capacitance of the varactor diode thereby changing the impedance of its resonance circuit, a cathode for a small signal diode is connected to the cathode of the varactor diode to apply the positive control voltage to the anode for the small signal diode. Thus, the deterioration in the oscillating characteristics caused when a low control voltage is received can be reduced. Then, the variable width of the oscillated frequency can be increased and the maximum control voltage can be reduced.
