Title: Inspecting apparatus for decarburization
Inventor: MATSUSHITA SATOSHI
IPC: G06T7/00
Filed: 1990-11-06
Abstract: PURPOSE:To make it possible to know the state of decarburization of the whole of a steel material sample with ease by picking up images of a plurality of regions along the periphery of the section of a substance to be inspected, by analyzing the state of decarburization of each region on the basis of information on the gradation density of each of the images and by displaying the analyzed state. CONSTITUTION:Density data of each image of a region A101 to be measured which a frame memory 323 takes in so that it covers the region with four image frames are added up for each divided sectors in the number of 255, and operation RAM 325 stores them. Next, a region A102 to be measured which is located at a central angle of 45 deg. from the A101 and further regions A103 to A108 to be measured are processed like the A101 and the RAM 325 stores integrated density data for each sector. These integrated density data are converted into smoothed density data and the RAM 325 restores them. Then, a decarburization depth, i.e. a distance from the edge of a steel material piece 101 to the position of the density of the surface not decarburized, is measured. Based on this decarburization depth, an image monitor displays decarburized places at positions corresponding to the regions A101 to A108. Accordingly, the state of decarburization of the whole of the steel material piece can be known with ease.

Title: Method for inspecting semiconductor integrated circuit

IPC: G06F17/50
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To guarantee the delay characteristic of a semiconductor integrated semiconductor circuit by means of simulation at the time of a design and the inspection of a test circuit without being affected by the outer load of the semiconductor integrated circuit. SOLUTION: Data inputted by a test data input terminal 2 is latched by the D flip flop 4 of a prestage by a clock signal inputted from a clock terminal 3 and is delayed with a delay component 6 by delay time td. The signal delayed by the delay component 6 is latched by the D flip flop 5 of a post stage. When the period of delay time td is set to be equal to a clock, the output signal of the D fIip flop 4 of the prestage cannot be latched by the D flip flop 5 of the poststage. When the value of the D flip flop 5 of the poststage is compared to be a high level or not by a test data output terminal 8, it can be discriminated whether the delay component 6 is larger than that of a test period, and the delay characteristic of a semiconductor integrated circuit can be guaranteed regardless of the outer load of the test data output terminal 8.

Title: Method and apparatus for correcting instrumental error in turbine meter
Inventor: SATOU SOUBUN
IPC: G01F15/02
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which a measuring error can be corrected when a flow rate is changed suddenly, by a method wherein a flow rate which is found on the basis of the speed of rotation of a turbine is corrected on the basis of differential pressures before and after the turbine. SOLUTION: Qm represents an actual flow rate, Qi represents a flow rate computed on the basis of speed of rotation of a turbine, and Qr represents a flow rate which is leaked from a gap between turbine blades or from a gap between the turbine blades and a meter housing. Then, the actual flow rate Qm=Qi+Qr. In addition, Pu represents a pressure value on the upstream side of a meter, and Pd represents a pressure value on the downstream side of the meter. Then, a differential pressure ΔP=Pu-Pd. In a steady flow, the differential pressure ΔP is increased monotonically with reference to the actual flow rate Qm, and the actual flow rate Qm=f(ΔP). When a flow rate is changed suddenly, the relationship between the flow rate Qr and the differential pressure ΔP is given by Qr≈Int (a×ΔP<1/2> )dt, where (a) represents a constant.  When the constant elements or the like are taken into consideration from other factors, the relationship is expressed by a function Qr=g(ΔP). In addition, since the function differs in every flow-rate region, it can be represented by Qr=h(ΔP, Qm). As a result, when the differential pressure ΔP and the computed flow rate Qi are known, the flow rate Qr and the actual flow rate Qm can be decided.
