Title: Density measuring device and method for fluid, viscosity measuring method for fluid using measured density, and original plate manufacturing method of sheeting type using measured density
Inventor: NAKA YUICHI
IPC: G01N9/26
Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To dispense with preliminary computation of a correlation between differential pressure and density through sampling or the like, and to compute an accurate fluid density by excluding a fluctuation in pressure loss as an error in a detection value even when the flow rate of a fluid flowing in a circular tube fluctuates. SOLUTION: A vertical tube 1 and an inclined tube 2 consisting of the circular tube having the same tube diameter as the vertical tube 1 and inclining at a constant angle to the vertical tube 1 are placed in communication. A differential pressure is measured between two points in the vertical tube 1 spaced in a line direction D, and between two points in the inclined tube 2 with the same interval. A fluid density ρ [kg/m3] is computed from an operation expression: ρ=(ΔP1-ΔP2)/ gL(1-sinθ)}, wherein L is the interval between pressure measuring means 3a (3a') and 3b (3b'); θ is the inclination of the inclined tube 2; ΔP1 is the differential pressure in the vertical tube 1; ΔP2 is the differential pressure in the inclined tube 2; and g is a gravitational acceleration.

Title: Circuit breaker
Inventor: HUNGER OLAF
IPC: H01H33/90
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a circuit breaker which can be manufactured inexpensively and its current contact can be protected from injury due to arc. SOLUTION: The circuit breaker is equipped with an arc extinction chamber 2 filled with a sulfur hexafluoride gas and extended to the longitudinal axis 3.
