Title: Fabrication of semiconductor device
Inventor: KURODA HIDEKATSU
IPC: H01L21/762
Filed: 1994-03-31
Abstract: PURPOSE:To eliminate the adverse effect of deformation of a wafer caused by the isolation process at the time of forming an element by performing the isolation process, comprising a step for forming an isolation trench and a step for filling the trench with a dielectric, after the element forming process. CONSTITUTION:An element forming process is followed by a process for forming an isolation trench 7 by photoetching technology. Subsequently, a BPSG film 8 of TEOS and ozone is deposited by atmospheric pressure CVD and oscillated through heat treatment thus filling the isolation trench 7 with BPSG. Consequently, deformation of a water caused by the isolation process has no adverse effect on the process following the element formation process requiring micromachining and the trench can be filled with a dielectric having relatively low heat resistance. This method enhances the profile of dielectric filling the trench along with the planarity thus allowing wiring over a trench filled with dielectric.

Abstract: PURPOSE: To considerably reduce the nitrogen in waste water by providing a nitrifying tank which biologically nitrifies the water used for eel raising, a denitrifying tank which denitrifies the same with anaerobic microbes, and a suspended solids filtering tank.  
     CONSTITUTION: Eel raising pond water enters a nitrifying tank 20 through an inflow water port 22, and circulates the inside of an aerating part 32 and plastic packing material part 25, after which it is introduced through the drop port 28 of the nitrifying tank into a simple sedimentation part 31, where suspended solids are solid- liquid separated and are sent through an outflow water port 30 into a denitrifying tank 40. The treated water flowed through an inflow water port 41 is subjected to reduction of nitrate nitrogen by the anaerobic denitrifying microbes stuck on plastic packing material 43, thence it enters a filter tank 60 through an inflow water port 61. When it passes the filter media 62 in the tank 60, it is removed of micro suspended solids, and is made into outflow water 65. Since the filter media 62 cause clogging upon long-term operation, discharge water is discharged from a backwashing water discharge pipe 68 according to need.

Title: Method of detecting leak from liquid transportation pipeline
Inventor: KOYANAGI YASUO
IPC: F17D5/02
Filed: 1980-05-15
Abstract: PURPOSE: To surely detect leakage and its position, by effecting difference operation on the measured values of measured signals, the time interval between which is by prescribed times longer than a sampling time interval.  
     CONSTITUTION: In a liquid transpotation pipeline 1, the pressure of liquid is always measured at a prescribed sampling time interval. In a central control room 6, a computer 9 performs difference operation on the measured values of liquid pressure signals which are adjacent to each other as to time. It is identified with leak that the difference operation value exceeds a setpoint. To detect the position of the leak, the difference between the arrival times of negative pressure waves at pressure measuring points at both the sides of the leak point is calculated by the computer 9. The difference operation is effected on the measured values of the measured signals, the time interval between which is at least twice longer than the sampling time interval. Though the time of pressure change due to actual leak is long, the slow pressure change can be detected by lengthening the time difference concerning the difference operation.
