Title: Bored precast pile construction method
Inventor: TSUCHIYA KOSABURO
IPC: E21B21/00
Filed: 1994-09-20
Abstract: PURPOSE: To reduce auger torque at the time of drilling due to a friction reducing effect, to improve earth removal efficiency, or to sufficiently reduce resistance at the time of erecting a precast pile in a bored precast pile construction method using mechanical drilling, whereby a precast pile can be buried and installed in the ground quickly and efficiently. CONSTITUTION: An earth auger 4 is lowered while being rotated to drill the ground E, and a bubble manufacturing plant 8 is operated concurrently with the above operation, whereby bubbles generated by a bubble generator 14 are ejected from the tip of the auger 4 through a swivel joint 6. The bubbles obtained by mixing air with an aqueous solution of water-soluble high polymer are different from the conventional bubbles obtained by using a surfactant or the like, and though the expansion ratio of the obtained bubbles is low, the tackiness and gravity are large so as to effectively reduce frictional resistance between soil particles, or between the soil particles and the earth auger 4 or a precast pile 20.  Thus, the auger torque at the time of drilling can be reduced, and the earth removal efficiency can be improved, or the resistance at the time of erecting the precast pile 20 in a drilled hole 30 can be reduced sufficiently.

A DNA capable of coding the aimed polypeptide is directly linked to the component (A) to afford a DNA, e.g. somatostatin expressed by formula II, capable of coding a fused polypeptide. A DNA which is a replication starting region, e.g. Bacillus subtilis, is introduced into a vector containing the components (A) and (B) to give a polypeptide secretion expression vector (C), which is then introduced into host cells, e.g. Bacillus subtilis, and transformed. The resultant microorganism is then cultivated to secrete and accumulate a polypeptide.

Filed: 1986-09-24
Abstract: PURPOSE:To take a high-accuracy test without causing a thin plate to buckle during the test by bending a test body which is constituted by superposing plural plate materials and integrating them except a test part repeatedly in the stacking direction. CONSTITUTION:The test body 13 is bent repeatedly by the reciprocal motion of the piston 22 of a testing machine 30.

Since the valve 16 is closed, the steam is moved to a pressurizing/ cooling tank 10 by the high pressure gas, and cooled by a fan 13 always held to an operating state to be condensed. When the operation state of the fan 13 is changed over to that of the fan 12, the heating/cooling tank 9 is cooled to be lowered in its internal pressure and the valve 14 is opened while the valve 15 is closed and steam is sucked in to the tank 9 from the module 11.

Title: Semiconductor logic circuit
Inventor: YAMAMOTO TAKAHIRO
IPC: H03K19/086
Filed: 1989-08-31
Abstract: PURPOSE:To extend the operation range of the supply voltage by providing a level shift circuit which shifts the potential of the supply voltage supplied to an ECL gate circuit, and supplying the output to a part of the ECL gate circuit. CONSTITUTION:The supply voltage of an ECL logic part 24 is supplied by the emitter output of a transistor TR 21; and when resistance values of resistors R11 and R12 are set to proper values, the current flowing to resistors R11 and R12 is suppressed to raise the potential of the emitter output of the TR 21, and the potential level is shifted in general. Thus, the emitter follower output potential of a first emitter follower output part 8 for the logical output of the ECL logic part 24 approximates potential points (a) and (b) of the emitter couple of an ECL logic part 10. Therefore, the potential applied to only a point (c) is dispersed overall, and this circuit is made strong against the power supply drop and can be used even with a shallow power bias because the potential is not applied to only the point (c).

Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To practice a quick quantitative analysis of impurity elements contained by fitting absorbance obtained through emission spectral analysis of a sample of solid vitrified carbon into a previously prepared calibration curve. SOLUTION: A solid vitrified carbonaceous material 1 differing in the contents of impurities serving as a standard sample is subjected to emission spectral analysis while in its solid form, and the absorbance of each spectral line is measured. The remaining part of the standard sample subjected to emission spectral analysis is electrolyzed in an alkaline solution 3, and a slurry prepared is subjected to a quantitative analysis using flame-less atomic absorption method to measure the concentrations of the impurities. The electrolysis is performed by soaking the material 1 as an anode and a platinum plate 2 as a cathode in the solution 3, and applying a dc potential. The absorbance and the concentrations of the impurities obtained are plotted to prepare a calibration curve for every impurity element.  Then, the absorbance of each impurity element which is obtained by subjecting the material 1 of the sample directly to emission spectral analysis is fitted into a calibration curve prepared in advance. Therefore, quick quantitative analysis of each impurity element contained is made possible.
