Title: Method for restoring aged pipe
Inventor: KAWABATA KAZUO
IPC: F16L1/00
Filed: 1993-07-30
Abstract: PURPOSE:To effectively reuse aged offshore and land pipelines without removal. CONSTITUTION:An aged pipe A is filled with a liquid (water, seawater, etc.) and a new inner pipe 1 smaller in diameter than the aged pipe A is inserted into the aged pipe A. The outside diameter and wall thickness of the inner pipe 1 are set so that the weight of the inner pipe 1 in the liquid approximates zero, and the end of the inner pipe 1 is closed. The inner pipe 1 is gripped by a clamp 2 that clamps the inner pipe 1 from its outer periphery, and an insertion force is applied to the clamp 2 by a drive mechanism (hydraulic jack, winch, etc.) that takes reaction at the insertion end portion of the aged pipe A. After insertion of one inner pipe 1 is complete, a new inner pipe 1 is connected by welding to the rear end of the inner pipe 1 and is inserted. These procedures are repeated to insert the inner pipes 1 along the overall length of the aged pipe A, and then the closed end of each inner pipe 1 is opened to finish the work of restoring the aged pipe A.

Title: Information transmission equipment
Inventor: TAKENO KOJI
IPC: H04B14/04
Filed: 1988-08-19
Abstract: PURPOSE:To improve signal compression efficiency by providing a correlation coder with plural inputs and a correlation decoder decoding the inputs and using a delay device to set the delay of the plural input signals. CONSTITUTION:When two input signals are right and left channel signals of stereo signals, the correlation between the two signals is high. Then the mean value of the absolute value of the output of a subtractor 13 is expressed in equation I, where C is a component of correlation between the two signals after a delay by a delay device, and Id1, rd2 are respectively components without correlation. Then the delay when the mean value of the absolute value minimizing the result of equation I is obtained, the result is used as an optimum delay and the result is outputted from a correlation coder 1 as a 1 byte data. Moreover, the relation of equation II due to high correlation exists and the information lost by 4-bit coding is not so much different from the result of a conventional coding. On the other hand, since the output of the subtractor 13 is a small value, the information lost even by 1-bit coding is sufficiently suppressed small.

Title: Testing apparatus of power transmitting mechanism
Inventor: ITANO SUMINORI
IPC: G01M13/02
Filed: 1984-10-04
Abstract: PURPOSE:To test the power transmitting mechanism under the conditions of pulsating torque close to the conditions of the operation of a reciprocating engine by using a motor, by providing a pulsating signal generating system which superimposes a pulsating signal on a rotary speed deviation signal of a constant speed control system for the motor that drives the power transmitting mechanism of a machine under test. CONSTITUTION:A vector control circuit 47 operates the instantaneous primary current command signal, frequency command signal and phase command signal for a motor 21 so that the induction motor 21 follows a torque command signal including a pulsating signal, which is generated by a pulsating signal generating circuit 44. Therefore, the average rotary speed of the motor 21 follows a set signal from a speed setter 41. At the same time, the generated torque follows the pulsating signal of the pulsating-signal generating circuit 44. Therefore, the motor 21 generates the pulsating torque corresponding to the pulsating signal generated by the circuit 44. On a power transmitting mechanism 11, which is driven by the motor 21, stress similar to that generated, when the test is conducted by an actual reciprocating engine, acts. Thus the testing apparatus having the characteristics closer to the reciprocating engine can be obtained.

Filed: 1994-08-31
Abstract: PURPOSE: To perform tracking without largely deviating the center of an objective lens from the center of a light beam by detecting a driving current of the objective lens and correcting a tracking error signal based on the driving current. CONSTITUTION: A low frequency component of the driving current of a tracking actuator 12 of an objective lens driving part 9 is detected by an objective lens driving current detecting circuit 14. Subsequently, the tracking error signal is corrected by subtracting the driving current from the tracking error signal from a differential amplifier 8 by an arithmetic circuit 15. The driving part 9 is controlled by a high frequency component of eccentricity of the corrected tracking error signal, while an optical head driving part 13 is controlled by a low frequency component. By this method, an offset of the tracking error signal due to movement of the objective lens at the time of following a track can be corrected, and a regenerative RF signal is prevented from deteriorating due to deviation of a spot from the track.

Title: Manufacture of plastic film
Inventor: BABA YUTAKA
IPC: B29C71/00
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of foreign matter accumulated on the surface of a film such as dust and a film composition by treating, at least, one of the surfaces of the film in a manufacturing step using an ultrasonic dust remover generating an air knife flow. SOLUTION: An ultrasonic dust remover removes foreign matter and dust accumulated on the surface of a film, in a manufacturing step, without damaging the surface of the film, by making the dust afloat with an ultrasonic pressure air ejected, in the form of an air knife flow, from a slit on a cleaner head. At the same time, microparticle dust is also removed by the ultrasonic effect. It is effective in the removal of foreign matter accumulated on the surface of the film to perform a discharging treatment prior to the ultrasonic dust removal. It is also desirable for the removal of dust when manufacturing the film to perform the ultrasonic dust removal with a film winder and in a slitter device, immediately before the film is wound in roll.  In addition, the ultrasonic dust remover preferably has a three-layer construction consisting of an air blower part, a suction part and an air blower part arranged in the longitudinal direction of the film.

Title: Sodium-sulfur battery
Inventor: KUNIMOTO ASAO
IPC: H01M10/39
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To improve corrosion resistance to sulfur vapor of the weld part of a positive electrode lid to a battery jar and minimize the thermal stresses applied to the connection part by using a ferrite-based stainless, having a chromium content of a specified wt.% in at least one of the positive electrode lid and the battery jar. SOLUTION: A ferrite-based stainless having a chromium content of 10-35 wt.% is used. This ferrite-based stainless preferably has a chromium-iron alloy later formed by chromizing on the surface. Accordingly, the vicinity of the welded part of a positive electrode lid to a battery jar can be prevented from being corroded by an evaporated positive electrode active material. Furthermore, since the difference in thermal expansion coefficients between the ferrite-based stainless and α-alumina is smaller than that between iron and α-alumina, the thermal stress due to heat cycle can be also small.
