Abstract: PROBLEM TO BE SOLVED: To reduce the disposal cost of sludge by reducing the amount of sludge generated while enabling stable treatment due to the lowering of an SV value by adding a field horsetail or an extract thereof to a process treating waste water biochemically. SOLUTION: Two systems of an A-tank using a field horsetail extract and a B-tank not using this extract are prepared and both systems are operated so as to be changed by regulating an inflow amt. so that BOD vol. load becomes 0.6, 0.8, 1.0 and 1.4 kg/m3.day at every almost 10 days. The field horsetail extract is regulated so as to become 20 ppm with respect to artificial sewage and the systems are operated so that the return ratio of sludge is 40% and aeration quantity is 0.3 l/min (intermittent aeration of 5-min interval). As a result, in the case to which the field horsetail extract is added, the generation amt. of sludge is reduced. That is, in the sludge increase amts. per a day of both tanks, the A-tank is 1.14 g and the B-tank is l.91 g. That is, a sludge conversion rate is reduced by about 1.5 times and sedimentation properties are also excellent.

Then a buried gate of P<+> layer is formed by diffusing boron into the P2 layer, and an oxide film 14 is stuck on a part of the P2 layer surface so as to bridge the N5 layer surface and a P2N5 junction. After that, an P<->2 layer is grown on the P2 layer on which the film 14 does not exist and on the P<+> layer surface by epitaxy applying the film 14. The P<+> layer having a concentration of about 10<18> in the initial growth process is changed to the P2 layer having a surface concentration of 10<16> after the growth, and a sheet resistance necessary for turn off is constituted thereby. In this manner, a GTO is constituted of a main GTO part 1, and an amplification GTO part 2 and a surge absorber part 13 between which the GTO main part is placed. The intercepting capability of this GTO is increased.

Title: Method for estimating resistance of steel product inserted into concrete
Inventor: YANAGIDA KATSUMI
IPC: G01N11/12
Filed: 1992-11-11
Abstract: PURPOSE:To estimate a value corresponding to an inserted resistance under actual construction conditions by expressing a relation of an inserted resistance value with respect to optional insertion depth of an intruded body having an angle and a speed into a concrete sample in a regression line. CONSTITUTION:An intrusion angle is adjusted by an interposing state of a fastener 4 and intrusion speed of an intruded body 2 is adjusted by the speed of a lever 5 respectively. An inserted resistance value of the intruded body 2 is displayed on a display 7 every time insertion depth into a concrete sample 1 increases. A regression line of the intruded body 2 having a certain angle and speed can be obtained from the results by the least square method. An intersection of the regression line with a vertical axis that is the inserted resistance value when insertion depth is zero indicates a bearing resistance value received by a bottom of the intruded body 2, while gradient of the line that is an amount of change in the inserted resistance value with respect to change in insertion depth indicates frictional, resistance received by a peripheral face. The resistance value obtained here is converted according to an actual steel product cross section thereby estimating the inserted resistance value of the steel product.
