Filed: 1982-09-03
Abstract: PURPOSE:To improve the quality of supernatant liquid and the ability in sludge dehydration by detecting how much the sludge in a concentration vessel is concentrated through a sensor, and inputting the detection data to a computer and controlling the detention time of the sludge in the concentration vessel to an optimum time. CONSTITUTION:A sludge supply pump 21 supplies inflow sludge 2 to the concentration vessel 1. Further, a sludge drawing-out pump 5 draws the concentrated sludge 3 out. Those pumps 21 and 5 are controlled through a computer 26 by the signal from a sensor 25 which is always set in the concentrated sludge in the concentration vessel 1. This computer 26 stores relation characteristcs (graph) between the previously found oxidation-reduction potential of the sludge and sludge staying time. A corrected oxidation-reduction potential measured value is found from output values of the sensor 25 such as the oxidation-reduction potential, temperature, pH, etc., of the sludge and an estimated sludge staying time and further a limit sludge staying time are calculated from the measured value and said stored relation characteristics, and consequently a sludge supply speed and a sludge drawing-out speed are controlled.

Filed: 1991-06-26
Abstract: PURPOSE:To facilitate counting of extra-fine foreign substance particles on a wafer surface whose sizes are abut 0.05mum by a method wherein the object wafer is exposed to a supersaturation vapor pressure state in a condensation chamber and the sizes of the foreign substance particles are enlarged by condensation reaction with the particles as nuclei and the number of the enlarged uncle is counted. CONSTITUTION:A wafer 1 is conveyed into a condensation chamber 12 and cooled to a predetermined temperature by a stage 21 whose temperature is controlled. Then alcohol is introduced into the chamber 12 from an alcohol bottle 23 through a flow rate controller 22 so as to obtain an approximate saturation vapor pressure. As the temperature of the wafer 1 is so controlled as to be several degrees to scores of degrees lower than the temperature of the side walls of the condensation chamber 12, the alcohol vapor near the wafer surface is cooled and put into a supersaturation state. If there are foreign substances on the wafer surface, alcohol is condensed with the foreign substances as nuclei and the sizes of the foreign substances are enlarged to the extent from 0.5mum to several microns. The wafer 1 is conveyed into a foreign substance counting chamber 13 and the number of the foreign substance particles is counted. With this constitution, the number of the foreign substances can be counted easily and the control and improvement of an LSI manufacturing process can be well managed.

Title: Method and device for bending glass sheet
Inventor: ESUKO YUHANI PERUTOONEN
IPC: C03C27/12
Filed: 1984-07-25
Abstract: A method of and a furnace assembly for bending glass sheets. Glass sheets (6) are conveyed in bending moulds (5) supported by cars (4) along an upper transport run (2) periodically from one heating section (10) to another. In the final heating section, temperature is risen so high that a glass sheet bends by the action of heat and gravity to conform with the surface of the mould. Thereafter, a car (4) together with a bent glass sheet is lowered onto a lower run (3) and returned to the outset of a furnace (1). On cooling, the glass sheets on said lower run emit heat to the glass sheets on said upper run through the open bottom structures of cars (4). The weight and heat capacity of the cars have been made as low as possible by removing the side and back walls thereof, whereby only the front or leading walls (8) provide locking walls between sections (10) successive in the longitudinal direction of the furnace.

Title: Bonding wire
Inventor: HIROTA HIDEKAZU
IPC: H01L21/60
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain a high-strength bonding wire suitable as a bonding wire for multipin semiconductor device, by a method wherein a specified amount of one kind of the element or more from the elements Co and Ni and a specified amount of Ge are made to contain in high-purity gold of a specified value or higher. SOLUTION: 0.05 to 2wt.% of one kind or more of the elements Co and Ni in the total amount and 0.05 to 1.2wt.% of Ge are made to contain in high- purity gold of 99.99wt.% or higher. The reason why the one kind or more of the elements Co and the Ni and the Ge are added complexly to the Au is to make possible the strength of a bonding wire enhance without reducing excessively the conductivity of the bonding wire by making a compound of the Co or the Ni with the Ge deposite finely in the Au. In the case where the addition amount of the Co or the Ni or the Ge is less than 0.05wt.%, the amount of a deposited substance is too little and the effect of the enhancement of the strength is insufficient.  In contrast with this, when the adding amount of the Co or the Ni exceeds 2wt.%, a reduction in the conductivity is caused and, when the adding amount of the Ge exceeds 1.2wt.%, an eutectic crystal of the Ge with the Au is generated to reduce the processability of the wire.

Title: Method for controlling sheet thickness in rolling mill
Inventor: KACHI TAKAYUKI
IPC: B21B37/18
Filed: 1988-06-23
Abstract: PURPOSE:To perform high accurate sheet thickness control independent of roll eccentricity by intentionally changing a rolling load target value to be a rolling load control value to correct a sheet thickness and controlling a rolling load to equal to the control value. CONSTITUTION:When a 4-high rolling mill 10 starts rolling, a rolling load at a rolling start point or an expected rolling load expected by rolling conditions are stored in a rolling load target value memory 34 as a rolling load target value. The stored target value is compared with an actual rolling load by a comparator 38 through an adder 36. A rolling controller 10 transfers a drafting command to a drafting device 18 based on a comparison result so that a rolling load of the mill 10 equals to the target value. A sheet thickness of a rolled stock 12 is equalized to the target value by well coping with roll eccentricity generated on work rolls 14 or backup rolls 16 by the feedback control of rolling load.
