Title: Removal method of existing steel pipe pile
Inventor: UEDA KOHEI
IPC: E02D9/02
Filed: 1994-07-20
Abstract: PURPOSE:To facilitate the removal of an existing steel pipe pile by pressurizing the inside of a steel pipe pile whose head is blocked and closed after penetration and exerting its inner pressure on a pile penetration ground. CONSTITUTION:After blocking the inside 11 of a pile by attaching a cover material 20 on the head part of a steel pipe pile 10, water is poured by a water pressure pump 30 and existing air is discharged entirely through an air vent valve 22 and replaced with the water. Then, after closing the air vent valve 22 and while continuing to pour the water and pressurizing the inside 11 of the pile, the uniform pressure acting on the inner surface of the steel pipe pile is applied to the ground 41 partitioned in the pile. The pressure acts so that the ground 41 may be pushed down at the lower part of the steel pipe pile 10, but the ground 41 itself is not pushed down extremely. Therefore, the reaction acts on the steel pipe pile 10 as an upward push up force. At the time of the inducement of an extraction behavoir, the pressurization by a water pressure pump is stopped and the steel pipe pile 10 is pulled out and removed by a hoist 50, etc.

Abstract: PURPOSE:To make the detection of malfunction of a lot of optical shutter devices easy, by discriminating the time interval of a high voltage division pulse of the optical shutter devices and a master pulse with a clock generating circuit, a counter circuit and a timing discrimination logical circuit. CONSTITUTION:An optical shutter device 4 opens an optical shutter with a high voltage pulse (e) and leads a pulse laser light (d). This pulse (e) is divided at a high voltage division circuit 5, becomes a low voltage pulse (h) and enters an optical shutter malfunction detecting circuit 6. Further, a master pulse (a) given to the circuit 6 enters a clock generating circuit 7 to generate a clock pulse (f). The pulse (f) is counted at a counter circuit 8, and a one-shot pulse (g) is generated after a delay time determined for laser oscillation. A timing discrimination logical circuit 9 receives the pulses (h) and (g) to detect whether or not the pulse (h) exits between the pulses (g), and the output can be discriminated as normal if existing and as failure if not.

Title: Aluminum alloy rolled sheet
Inventor: TAJIRI AKIRA
IPC: B21B3/00
Filed: 1986-08-15
Abstract: PURPOSE:To prevent quality degradation and to eliminate excessive rolling oil consumption by reducing the total deposit amount of remaining substances due to a rolling oil and the remaining rolling oil on the surface of an aluminum alloy sheet down to a specific amount or less and preventing oil film breakage in multistage forming. CONSTITUTION:In the case of multistage pressing an aluminum alloy rolled sheet after cleaning the surface of the sheet and applying a rolling oil to the surface, the total deposit amount of remaining oil amounts and remaining oxides and carbides due to the lubricating oil on the surface being more than 15mg/m<2> adversely generates scratches on the rolled sheet or adhesion of aluminum to a metal die. Therefore, the deposit amount is reduced to 15mg/<2> or less to obtain a good formability without lubricating oil film breakage and generation of forming cracks, scratches, and gallings. The production cost is reduced because of nonuse of excess rolling oil.

Filed: 1992-06-25
Abstract: PURPOSE:To simplify structure, to simultaneously observe entire visual field and the position of a masking aperture, and to reduce the deterioration of an image by synthesizing the image of a sample which does not pass through the aperture and the image of the aperture to be in the same positional relation as in the case of infrared measurement. CONSTITUTION:The image of the sample S is formed at the position of the aperture 2 by an objective optical system 5, and in the case of measurement by visual observation, simultaneously, the image is also formed on an image surface I by a half mirror 3 arranged halfway and transmitted to an optical system 7 for visual observation. The image of the aperture 2 is superposed on the image of the sample S so as to be observed in the optical system 7. Since illumination for the aperture 2 is independent of illumination for a sample in the optical system 7, the color of the illumination for the aperture is changed by interposing a filter, or the image of the aperture may be colored by coloring the edge or the whole of the aperture 2 and the back of a mirror 4. Then, the synthetic image is easily changed in accordance with the kind of the sample S, and the image of the aperture is easily discriminated from the image of the sample.

Abstract: PURPOSE:To facilitate the detection and extraction of a stuffing pulse by making the word length of the stuff pulse to be inserted to match the encoding speed of a picture signal to the transmission speed equal to that of the picture signal, and by using a different code. CONSTITUTION:A television signal from an input terminal 1 is converted to a PCM signal by an A/D converter 101. A control separation TDM circuit 102 applies a digital signal processing, and separates the signal into a brightness signal Y and two color signals C1 and C2, then time base compresses time, and later multiplex them by time division in the horizontal blanking period of the signal Y and constitutes a TDM signal. A limiter 103 limits the TDM signal in a certain range, and prohibits the use of a code pattern showing a specific value in order to use the pattern as a unique word for video frame. The address signal of an elastic memory 105 is supplied from an address generat ing circuit 113. When the amount of storage information of the memory 105 becomes less than a prescribed threshold, the reading of data from the memory 105 is prohibited, a dummy pulse is inserted instead. Accordingly, on the recep tion side, the dummy pulse can be extracted only by supervising the word pat tern.
