Title: Coriolis mass flowmeter
Inventor: OSAWA NORIKAZU
IPC: G01F1/84
Filed: 1991-02-27
Abstract: PURPOSE:To reduce the influence of vibration noise by estimating a normal flow-rate signal by comparing flow-rate signals of two systems with each other and outputting the estimated flow-rate signal. CONSTITUTION:A pipe through which a fluid to be measured flows is excited at the first frequency by means of an exciting machine 20 set at a prescribed position of the pipe. The pipe is further excited at the second frequency by means of exciting machines 21 and 22. The displacement of the pipe caused by the excitation is detected by means of a pair of displacement sensors 23 and 24. The first signal processing means calculates the flow rate of the fluid by using the first frequency component of the displacement signals detected by the sensors 23 and 24 and outputs the first flow-rate signal. The second signal processing means outputs the second flow-rate signal by using the second frequency component of the displacement signals. The first driving means drives the machine 20 by using the first frequency component and the second driving means drives the machines 21 and 22 by using the second frequency component. Then, a noise discrimination circuit 39 discriminates the presence/absence of noise based on the variation of flow rate between the first and second flowrate signals and outputs a normal flow-rate signal after estimation.

Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a stable detection voltage level even in a case of intermittently applying abnormal voltage by setting, at least, a pair of electrodes formed on an insulating substrate via a gap to have such characteristics as disappearing partially by discharge in applying the abnormal voltage and restoring by itself. SOLUTION: When an abnormal voltage is applied on a pair of electrodes 3, 4 formed on an insulating substrate 1 via a gap 2, discharge is started in a part having the lowest resistance value between the electrodes 3, 4. When the abnormal voltage disappears in the electrodes of discharging, for example, a1, a2 simultaneously with the discharge, the electrodes in the part having the lowest resistance value, for example b1, b2 start, discharge and disappear simultaneously with the discharge. On and after the third abnormal voltage, the same is repeated and in each case, the electrodes return to their original states after application of the abnormal voltage by the self restoration action. This constitution can protect the circuit components by connecting the circuits, which are easily affected by external surge voltage, etc., in parallel.

IPC: H01L21/3205
Filed: 1988-02-16
Abstract: PURPOSE:To make the surface of an interlayer insulating film which covers a lower layer wiring flat without requiring a levelling process by a method wherein the lower layer wiring is formed so as to fill trenches formed in an insulating film under the lower layer wiring. CONSTITUTION:A lower layer insulating film 2 is covered with a resist film except the parts where wiring patterns are formed and trenches 6 are formed in the insulating film 2 by etching. Then, while the resist film is left, a wiring metal layer 30 which has a thickness large enough to fill the trenches 6 is applied over the whole surface. After the resist film is removed with the wiring metal layer 30 on it to leave wirings 3 in the trenches, the whole surface is covered with an interlayer insulating film 5. If the wiring metal layer 30 is applied and then the wiring metal layer 30 remaining on the surface except the trenches is removed by lift-off, the wiring metal layer 30 filling the trenches 6 is left and its upper surface is at nearly the same level as the lower layer insulating film 2. With this constitution, the surface of the interlayer insulating film 5 covering the wirings 3 and the insulating film 2 can be flat and the problem of step coverage can be resolved without requiring a levelling process.
