IPC: G01N3/00
Filed: 1995-06-08
Abstract: PURPOSE: To quantitatively evaluate a load margin to crack unstable breakage in an object. CONSTITUTION: A data input part 12 detects the temperature of an evaluation object 1 with a temperature sensor 11 and at the same time, measures the load. An FEM analysis part 13 models an evaluation object part 10 of the evaluation object 1 and a rod test piece 14 into finite elements so as to analyze them by the FEM and a stress hysteresis data 15 in the adjacent of a crack part 2 and stress data 16 in breaking are calculated by a numerical analysis. A Weibull stress analysis part 17 finds the Weibull stress σw from the stress conditions in the adjacent of the crack part 2 and the distribution of breakage probability of the Weibull stress σw in relation to respective temperature conditions is found from the rod test piece 14.  And, the relation of the Weibull stress - the breakage probability found by the Weibull stress and a material test of the evaluation object part 10 is analyzed so as to measure the time change in breakage probability and monitor load margin up to a preset breakage probability.

Title: Inspection method and device for spark plug, and production method of spark plug
Inventor: HAMADA TAKAO
IPC: H01T21/02
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To realize an inspection method for spark plug capable of accurately determining electrode edge lines facing each other interposing a spark gap in between. SOLUTION: Illumination lights L from a luminous part arranged surrounding an axial line O on the front side in the axial line direction of a central electrode W1 are radially concentrated to the tip end of a spark plug W from the diagonal front outside the central electrode W1 toward the axial line O for illumination to photograph a spark gap part. Since the illumination lights L are introduced diagonally from outside the central electrode W1 to the spark gap (g), strong reflection from the surface of a ground electrode W2 to the axial line direction of the central electrode W1, that is, photographing direction of the spark gap is suppressed and unclear result of edge line image of the ground electrode W2 is suppressed. Also, the illumination light RF1 reflected on the surface of an insulator W4 positioning behind the ground electrode W2 comes to illuminate the ground electrode W2 from the back and so the edge line of the ground electrode W2 can be clarified owing to a silhouetting effect.

Filed: 1985-06-28
Abstract: PURPOSE:To simplify structure and shape of a safety valve body and thereby reduce manufacturing cost, by closing a pressure relief hole of a valve body of a safety valve by means of a valve member, and forming the valve member of a shape memory alloy. CONSTITUTION:A pressure relief hole 3 formed in a safety valve 1 is opened and closed by thermal deformation of a valve member 4 formed of a shape memory alloy. At a temperature lower than a safety operation set temperature of the alloy, the valve member 4 is in tight contact with the pressure relief hole 3, and a sealability of the safety valve may be maintained with a high accuracy even when an inner pressure of a pressure vessel increases to some extent. Further, when a temperature at the periphery of the pressure relief hole increases to a value higher than the safety operation set temperature, and the inner pressure of the pressure vessel is abnormally increased, there is generated a gap between the valve member 4 and the pressure relief hole 3 to relieve the inner pressure through the gap since the valve member 4 itself is deformed by a shape memory function.

IPC: H04L27/14
Filed: 1990-05-31
Abstract: PURPOSE:To obtain a binary digital signal equivalent accurately even when a DC component of a detection signal is fluctuated to an original signal by synthesizing a positive peak and a negative peak and using the synthesized level as a threshold level so as to identify the detection signal to be the binary digital signal. CONSTITUTION:A detection signal is band-limited by filter circuits 1, 5, 6, 7, 11, 12, 15 and enters positive peak hold circuits 2, 13, 16 and negative peak hold circuits 3, 14, 17. A positive peak is detected from the detection signal entering the positive peak hold circuit, a capacitor 13 holds the positive peak and a negative peak is detected from the detection signal entering the negative peak hold circuit, a capacitor 14 holds the negative peak. The positive and negative peaks are synthesized by resistors 8, 9 and the synthesized value is a threshold level Vt of the comparator circuit. The comparator circuit uses the threshold level Vt to identify the detection signal from the filter circuit to be a binary digital signal. Thus, an accurate binary digital signal without effect due to the fluctuation in the DC component of the detection signal is obtained.

The specified temperature is thus maintained because the displacement of the gas is adjusted to what it is required. The concentration of the processing liquid simultaneously becomes uniformed. For this reason, the quality of processing products is improved.
