Patent JP-H01206222-A (JP)
Title: Measuring apparatus of flow rate
Inventor: HASEGAWA YOSHIHIKO
IPC: F16T1/48
Filed: 1987-11-13
Abstract: PURPOSE:To enable the simultaneous measurement of a flow rate of vapor and a flow rate of condensate by one measuring apparatus, by using a flow rate measuring apparatus constructed of first and second measuring chambers connected by an orifice and of a weir hole formed in the second measuring chamber. CONSTITUTION:Condensate getting in from an inlet 2 enters first and second measuring chambers 5 and 6 and flows out into a draining space 7 through a weir hole 9. The first and second measuring chambers 5 and 6 are connected by an orifice 12 formed in the upper part of a partition wall 10. When a valve means fitted on the downstream side of a flow rate measuring apparatus thus constructed drains only the condensate and no leakage of vapor occurs, therefore, the liquid levels of the first and second measuring chambers 5 and 6 are the same. Accordingly, the flow rate of the condensate can be measured from the liquid level of the second measuring chamber 6 and an area of opening of the weir hole 9. When the leakage of vapor occurs, on the other side, the vapor flows to the second measuring chamber 6 through the orifice 12 and causes a difference in the liquid level between the two measuring chambers. Accordingly, the quantity of leakage of the vapor can be measured from the relationship between this difference in the liquid level and the area of the opening of the orifice 12.

Filed: 1990-10-25
Abstract: PURPOSE:To reduce CAD data volume and photo data volume by plotting a wiring pattern by a plotting line having line width convenient for the design of the wiring pattern without depending upon the plotting line width of a photoplotter device. CONSTITUTION:A CAD system 1 forms a wiring pattern on a printer board by using an optional line width without depending upon the plotting line width of the photoplotter device and forms wiring pattern data.

Title: Method for defoaming quartz glass
Inventor: SEGAWA HIDEAKI
IPC: C03B32/00
Filed: 1987-11-17
Abstract: PURPOSE:To readily carry out defoaming of quartz glass without changing a shape in a short time and dramatically improve product yield, by coating cellular quartz glass with a metal or glass and hot-pressing the resultant quartz glass using a hot isotropic press. CONSTITUTION:Cellular quartz glass is coated with a metal or glass and heated at >=1200 deg.C and under >=1MPa to carry out defoaming of the quartz glass. When the metal is used to coat the quartz glass, a container of shape close to that of the quartz glass is prepared from a high-melting metal, e.g., molybdenum or tungsten, and the quartz glass may be placed therein to hermetically seal the container with a lid made of the metal under a vacuum. The reason why the quartz glass is coated with the metal or glass is that contact with a gas is avoided, since there is a fear of coloring the quartz glass or causing strain if the gas as a pressure medium is mixed therein.
