Title: Method and apparatus for inspection of leak
Inventor: FURUSE AKIO
IPC: G01L19/04
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To execute the inspection of a leak in a short time and precisely even when a temperature environment is changed by a method wherein a differential-pressure change value which corresponds to a true leak amount is estimated and computed so as to be found for every object, to be inspected, by using a specific expression and the existence of the leak is judged on the basis of whether its computed result is large or small. SOLUTION: A differential-pressure-change measuring means 40 is constituted of a reset-signal generator 44 or the like which applies a gas pressure to an object 20, to be inspected, and to a reference tank 21 and which gives a reset signal to an automatic zero reset-type amplifier 31 at unit time intervals. Differential-pressure change values a1, a2, a3 per unit time which are detected by the differential-pressure-change measuring means 40 are sent to a computing and control device 43 via a sample-and- hold circuit 41 and an A/D converter 42, The differential-pressure change values a1, a2, a3 as measured values which are input from an input port 43D are substituted into an expression by a computing means 43C-2, and a differential-pressure change value C in a state that a drift is removed is calculated.  Then, the differential-pressure change value C is compared with a set value by a comparison and judgment means 43C-3, and the existence of a leak is judged.

Title: Production of rigid granulated blast furnace slag
Inventor: TOUBOU HIROYUKI
IPC: C04B5/02
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To efficiently produce a rigid granulated blast furnace slag by specifying conditions of the flow rate of spray water/flow rate of a molten blast furnace slag (weight ratio) and water temperature in a granulating tank. SOLUTION: A rigid granulated blast furnace slag is produced under conditions of >=30 value of the flow rate of spray water/flow rate of a molten blast furnace slag (weight ratio) and <95 deg.C water temperature in a granulating tank in a step for granulating the molten blast furnace slag and producing the granulated blast furnace slag. Although the slag in an intactly granulated state does not satisfy >=1.45kg/L unit volume mass which is the JIS standard, the unit volume mass of the granulated slag having >=1.35kg/L is surely improved to >=1.45kg/L unit volume mass by crushing the granulated slag and regulating the grain size thereof. Thereby, the granulated slag may be produced under granulating conditions of >=1.35kg/L unit volume mass of the slag.  For that purpose, the ratio of the flow rate of the spray water/flow rate of the molten blast furnace slag is initially regulated to >=30 and the water temperature in the granulating tank is regulated to <95 deg.C. This is because the amount of generated steam is large when spraying water and cooling the slag and the amount of the present closed pores after the cooling is increased to reduce the bone-dry specific gravity (apparent density) and further the unit volume mass.
