摘要： PURPOSE:To enable an embedded member to be released easily and quickly without damaging molds and products by keeping a sufficient draft even if the surface of the mold is tilted, and enabling the embedded member to be supported without bringing an embedded metal fitting and the like into contact with the mold. CONSTITUTION:An embedded member 1 for anchoring to a concrete product 3 by the embedding of an embedded part is supported against a support plate 4 with the embedded part exposed, the support plate 4 being made greater than the part of the member 1 exposed from the product, so as to have a sufficient draft. The support plate 4 is fitted into a hole 7 provided in a mold 2 for molding the concrete product 3, and an anchoring means is engaged in the embedded member 11 so as to anchor the support 4 to the mold 2.

摘要： PURPOSE:To improve efficiency, to decrease treating cost and to make a nonpollution type being friendly to the earth environment by a method wherein carbon dioxide gas is continuously introduced into a strong alkali water soln. by utilizing a negative pressure generated on the rear face of a rotating impeller and fine gas bubbles are generated to perform neutralization. CONSTITUTION:When a rotating shaft 22 is rotated by actuating a driving motor 26 of a gas-liq. mixing apparatus 20, an impeller 21 is rotated in an alkali water 15 to generate a spiral flow and a negative pressure is generated in the alkali water on the rear face in the rotating direction of the impeller 21. Carbon dioxide gas is introduced into a container 14 from a carbon dioxide gas inlet 27 formed on the lower part of a cylindrical body 25 through an inlet pipe 28 from a feeding source (a carbon dioxide bomb) and is mixed into the spiral flow. The mixed carbon dioxide generates a large amt. of fine gas bubbles by a shearing force of the spiral flow and the impeller 21 to increase the contacting area between alkali water and carbon dioxide and the alkali water is neutralized by making carbon dioxide efficiently dissolved and absorbed into the alkali water.

摘要： PURPOSE:To prevent the back flow of concrete while sufficiently working concrete pressure by forming an annular sealing section made of an abrasion- resistant rigid material, the surface of which is formed in an inclined plane, to the outer circumferential surface of the tail section of the main body of a shield machine. CONSTITUTION:An annular body composed of a rigid material having excellent abrasion resistance such as band steel is installed integrally onto the outer circumferential surface of the tail section of the main body 1 of a shield machine through bolt clamping, welding, etc. Two inclined surfaces inclined downward in the before and behind direction while using approximately the center as a boundary are shaped so as to be tilted in the backward direction as a whole in an annular sealing section 2. The main body 1 of the shield machine is propelled while excavating a bedrock 4 by a shield excavator and a tunnel is constituted, and concrete 5 is placed into the clearances among formworks 3 and the bedrock 4 through a pipeline 7. Accordingly, the back flow of concrete 5 can be prevented while friction between the main body 1 and the bedrock 4 is reduced, thus smoothing excavation.

摘要： PURPOSE:To improve the operational efficiency, by providing a second control point in front of a first control point and varying a current indication and a control signal simultaneously at the second control point when a signal current indication varies between two control points. CONSTITUTION:If a ground signal unit 4 has an R current indication when a vehicle 2 passes through a control point P1 for producing a stop pattern, a signal is received by a vehicle mounted unit 6 through coupling between a ground slave unit 5 and a vehicle mounted slave unit 61, whereby a stop pattern is produced in a vehicle mounted controller 63 in order to stop the vehicle 2. If a current indication up signal is inputted at point Pr after the vehicle 2 passed through the control point P1, current indication up is delayed until the vehicle 2 passes through a control point P3. Passage of the vehicle 2 through the control point P3 is detected through a vehicle detector 8 to bring the ground signal unit 4 into Y current indication thus providing a Y current indication signal to the vehicle mounted slave unit 61 from the ground slave unit 7. Consequently, stop pattern is released and the vehicle is controlled to a speed corresponding to Y current indication.

摘要： PURPOSE:To prevent the occurrence of a fire of a rolling stock in a long tunnel by collecting temperature data of the sides of the rolling stock, editing the temperature data into temperature data corresponding to the respective positions of the rolling stock, and comparing the data with designated high-temperature data of each rolling stock to judge an overheat portion. CONSTITUTION:Axle detectors 21, 22 are installed to detect the approach of a train and the approach speed, and plural axle detectors 23-26 are installed at designated spaces in order to detect separation of rolling stocks of a train. Heat detectors 28-33 for detecting the outside temperature of the rolling stock are disposed vertically on both sides of rails. Detecting signals (data) of the above respective detectors are input to a control box 36. In the control box 36, temperature data is accumulated corresponding to a portion of a rolling stock, and on detecting that a train leaves a measuring block, the temperature data is transmitted to a data analyzer to detect overheat of the rolling stock while being compared with previously stored high temperature portion data peculiar to the rolling stock in the data analyzer.

摘要： PURPOSE:To enable highly accurate testing, by measuring a surface contact pressure at positions of different seal material with first and second water pressure resistance testers to calculate the life of the seal material in practice based on output values obtained with the testers. CONSTITUTION:A surface contact pressure is measured with a first water pressure resistance tester 7 with respect to seal groove 23a of a seal material varying with a water passage flow rate. Likewise, a surface contact pressure is measured with a second water pressure resistance tester 8 about a seal material at a position differing from the position of the previous seal. A computer multiplies endurance determined from the results of measurement from the first water pressure resistance tester 7 by an endurance day and hour of the two seal material obtained based on the results of measurement from the first and second water pressure resistance testers 7 and 8 to calculate the life of the seal material is practice.

摘要： PURPOSE:To enable a reliable detection, for a track section through which signal current synchronous with the frequency of train current flows, by detecting the fact that asynchronous current has flowed in due to leakage baed on the presence of a higher harmonic component together with a modulated wave in the output of a demodulator. CONSTITUTION:A portion adjacent to a synchronous section TP and a asynchronous section TB which are separated by inserting an insulating material 4 to rails 3 is provided with a detection loop 5 composed of transceiver coil. The component of frequency fP is extracted from the train current PS of the synchronous section TP, a sending carrier wave fC1 is generated by an oscillator 12, a modulated wave fS of lower frequency thereof is also generated by an oscillator 14, a sum frequency fi is generated by a modulator 15, and a sending signal fA is generated by a modulator 16. On the other hand, the sending signal fA and the 15th higher harmonic wave fb of the current fS passing to the asynchronous section TB are extracted by BPF23 and given to a demodulator 24, the output thereof is sent to a detector 26, and a leakage detecting output is sent out when the higher harmonic component is larger than the modulated wave.
