Title: Ultrasonic flowmeter
Inventor: OWADA HIROSHI
IPC: G01F1/66
Filed: 1986-06-25
Abstract: PURPOSE:To accurately measure the flow rate of each of various fluids having different sonic velocities in a real time, by using a model route estimated on the basis of an actually measured value and correcting the flow rate of a fluid to be measured on the basis of the flow rate correction coefficient calculated by estimating sonic velocity in the fluid to be measured. CONSTITUTION:A change-over switch 7 is changed over to one side to set, for example, such a state that the drive pulse DP from a drive circuit 6 is emitted from a transmitter-receiver 4 to a transmitter-receiver 3 and a propagation time T1 is measured by an operation circuit 10. The switch 7 is changed over to measure a propagation time T2 in the same way to calculate propagation time difference DELTAT. Since the time difference DELTAT is inversely proportional to a flow rate Q, the flow rate Q is calculated according to a predetermined formula. A total propagation time TS is operated based on a predetermined formula according to a model of a propagation route. The average value of actually measured propagation times T1, T2 is taken to obtain a propagation time T which is, in turn, compared with the total propagation time TS to calculate the propagation time T0 of the ultrasonic wave propagating through a fluid to be measured and coming to T=TS and an angle of refraction and the correction coefficient KX to the flow rate Q is calculated. By multiplying the coefficient KX at the operation time of the flow rate, correction having all of factors taken therein becomes possible in a real time.

Title: Thermoelectric conversion element
Inventor: NISHIO YOSHIMASA
IPC: H01L35/18
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To easily improve the energy conversion efficiency by a process other than the grouping of the kinds and composition ratios of metals by a method in which thin films made of respective two kinds of thermoelectric conversion alloys are alternately stacked to make a difference in potential or temperature on the end in the direction orthogonal to the thin films. SOLUTION: The entire thermoelectric conversion element is made of Bil-x Sbx . Furthermore, the first thin films 1 setting up x to be 0.08<=x<0.13 and the second thin film 2 setting up x to be 0.13<=x<0.25 are alternately stacked. Since the electrons existing on the low temperature side of the thermoelectric conversion elements receiving less energy have low energy while the electrons existing on the high temperature side receiving much energy have high energy. Resultantly, the thermoelectric elements are charged to generate an electric field.

Title: Preparation of electrochromic element
Inventor: ISHIWATARI KAZUYA
IPC: G02F1/1524
Filed: 1983-08-18
Abstract: PURPOSE:To improve appearance of a pattern by laminating an electrochromic (EC) layer on the first electrode, and bringing an Ar atm. excited by glow discharge into contact with the parts of said EC layer not to be used as said EC layer to erase the EC function. CONSTITUTION:An EC layer 3 is laminated on the first electrode 2 formed on a base plate 1, and then, an atm. of Ar excited by glow discharge, such as ion plating, is brought into contact with the parts of the EC layer 3 not to be used as said EC layer to erase the EC function and form a pattern. An insulating layer 4 is formed on the layer 3, and further, the second electrode layer 5 is formed on this layer 4. Ar ions are produced in the Ar atm. excited by such a glow discharge and attack the parts of the layer 3 to form an intended pattern. Since the EC layer itself is divided into the parts having the EC function and the parts having no EC function by this treatment, the layer 3 has no or very little level difference, and hence, an EC element good in appearance can be obtained.
