Filed: 1986-09-16
Abstract: PURPOSE:To facilitate terminal connection, by mounting insulating materials, only pad parts of which are opened, on an IC chip and inducing conductors through the opening parts of these insulating materials and equipping top ends of these conductors with output terminals. CONSTITUTION:IC output terminals 2 are converted into output terminals 4 with surface areas larger than those of the terminals 2 and the terminals 4 are spaced larger than the terminals 2.

CONSTITUTION:In the vicinity of a upper front slope IC, a finder is provided with an optical member 3 having the third display reflecting plane 3b, which totally reflects light from a display body S and leads the reflected light to the first display reflecting plane M2 via the upper front slope IC. As it does so, the inclination angle of the third display reflecting plane 3b is set in such a way that the critical reflected light beams of light made incident from the display body S is positioned between the lower edge of the eyepiece side 7 and upper edge of the first display reflecting plane M2; and the light from the display body S totally reflected from the third display reflecting plane 3b is led to the first display reflecting plane M2 but is prevented from coming out of the eyepiece side 7. Thus, the display body S or a ghost picture in the vicinity of it do not pass through a non-normal optical path and consequently are not observed in the finder.

Abstract: PURPOSE:To increase the utilizing efficiency of silane gas by causing plasma discharge after heating the silane gas to the temperature which is slightly lower than a decomposition temperature of that. CONSTITUTION:Gas is introduced into an oven core tube from a gas bomb 21a of silane, e.g., 20% of monosilane diluted by hydrogen and if necessary, the bomb 21b of a doping gas through a pipe 25c. Meanwhile, exhaust of the air in the oven core tube is continued by a mechanical booster pump 32 and an oil rotary pump 33 so as to make the pressure 0.5-1.5Torr. At the same time, the inside of oven core tube is heated to 200 deg.C by an electric oven 26 and high frequency waves are applied to two sets of electrodes connected by every two electrodes by a high frequency oscillator 31. After that, the wide part 35 of the gas pipe is heated to 350-390 deg.C which is slightly lower than the decomposition temperature 400 deg.C of monosilane gas by a heater 36. The monosilane gas which has been flowing in the gas pipe 25c slows down in the wide part 35 where it is heated sufficiently and it is introduced into the oven core tube. As this gas is given sufficient thermal energy, decomposition by plasma discharge occurs easily.

Title: Measuring and controlling method for flow rate of boiler blow water
Inventor: HIKASA KATSUHIRO
IPC: G05D21/00
Filed: 1988-08-31
Abstract: PURPOSE:To dispense with the preparation of a flash tank by determining a flow rate FB of boiler blow water by the computation of FB=FD (hS-hD)/(hS-hB) on the basis of a measured value F0 of a flow rate of flash drain water and each of enthalpies hB, hS and hD. CONSTITUTION:A third function computing means 14 outputs an enthalpy difference (hS-hB) on the basis of a measured value TD of temperature from the relationship between a temperature TD (TS) approximated by one straight line and an enthalpy hS-hD. A subtracting means 15 computes the product FD (hS-hD) of an output (hS-hD) of first and second function computing means 12 and 13 has a measured value FD of a flow rate of flash drain water. A dividing means 17 conducts division of FD (hS-hD) and (hS-hD) and calculates a flow rate FB of boiler blow water according to a formula FB=FD (hS-hD)/(hS-hB). A computation error is very small in this case, and special preparation of a flash tank, which is usually provided for treating the boiler blow water, is dispensed with.
