Title: Repairing method of pipe
Inventor: TAKABA OSAMU
IPC: F28F11/00
Filed: 1983-10-24
Abstract: PURPOSE:To fluid-tightly repair the damage part of a pipe against the fluid in high temperature and under high pressure flowing through the pipe, by heating the pipe, anealing it, and by expanding it by inserting a sleeve having annular projections around it into the pipe, and then by fixing the sleeve in the pipe by letting the annular projections bite into the inside wall of a pipe. CONSTITUTION:When a pipe 3 is repaired, the pipe is set on a pipe plate 2. It is expanded to the whole extent of thickness of a pipe plate 2, and is heated by inserting a heater 5 into it. The pipe 3 is annealed by heating, then a gap is produced between the pipe 3 and the pipe plate 2. Besides, the effect of expanding work in the pipe 3 is gone out by the effect of annealing, and the pipe becomes nearly in the state of raw material. In this state, a sleeve 6, which is slenderer than the pipe 3 and has annular projections 7 around it, is inserted into the pipe 3, and the sleeve is expanded by a pipe expander 9. The annular projections 7 of a sleeve 6 bite into the inside wall of a pipe 3, and the sleeve 6 is fixed to the pipe 3. Then the other end of the sleeve 6 is fixed to the pipe 3 in the same manner. By this method, the inner part of a pipe 3 is completely shut off from the damaged part 4 by the sleeve 6, so that fluid-tight repair can be worked out to the damaged pipe.

Title: Seal ring
Inventor: NORIMATSU SHIZUO
IPC: F16K1/226
Filed: 1990-07-27
Abstract: PURPOSE:To provide a seal ring having a low resilient force without damaging the sealing ability of the seal ring by peripherally alternately locating a plurality of sets of the seal rings having a constant outside diameter but respectively large and small bores, in a notched annular seal ring. CONSTITUTION:A seal ring 3 is formed in a notched annular shape, i.e. an annular shape having an opening, and the outside diameter thereof is constant. In a bore, a plurality of sets of large parts and small parts are peripherally alternately arranged. When two so formed seal rings are inserted in the groove of a valve body 2, an amount of fluid leaking through the opening part can be reduced through the combination. Since the sectional factor of an object proportions the cube of width, when the width of the seal ring 3 is reduced to a half, a sectional factor is 1/8, and a power required from opening and closing of a valve body 2 is sharply reduced. This constitution remarkably reduces a power required for opening and closing of a butterfly type valve compared with the power of a conventional type, and besides only slightly increases a leak amount.

Abstract: PURPOSE: To make volume resistivity high, and temperature dependability low by letting the electrical insulating material be made out of ethylene (co)polymer the density, a melt flow rate and electrical activation energy of which is in a specified range, and of resin containing other polyolefin. CONSTITUTION: This invention is concerned with electrical insulating material which is made out of 2 to 100% ethylene (co)polymer by weight where its density is 0.86 to 0.97g/cm<3> , its melt flow rate(MFR) is 0.01 to 200g/10min and its electrical activation energy is less than 0.4 (eV), and of resin containing 0 to 98% other polyolefin by weight. Ethylene (co)polymer the density of which is less than or equal to or more than the aforesaid rang, is practically hard to manufacture. When a MFR is less than the aforesaid range, its forming processability is inferior, and when the MFR exceeds the specified range, its mechanical strength such as impact resistance and the like are inferior. And the ethylene (co)polymer the electrical activation energy of which exceeds the aforesaid range, is high in temperature dependability for volume resistivity.

Title: Method and device for adaptive control for resistance welding
Inventor: KIMURA TOSHIO
IPC: B23K11/24
Filed: 1986-08-26
Abstract: PURPOSE:To perform the satisfactory resistance welding in a prescribed time at all times even if a welding condition is different by detecting the time of the welding resistance maximum value between electrode tips after electrification is started and integrating the quantity of decrease of the resistance extending to the prescribed time after that to control a welding current. CONSTITUTION:The resistance between the electrode tips 1 after the electrification is started is reduced by the fitting of the pressing surface and the resistance is increased by the rise of the temperature after that. Next, an electrification area is increased by the generation of a nugget and the resistance is decreased gradually. When this resistance maximum value is R2, a point of time T2 is detected by a peak detection circuit 4 and the quantity S2 of integration of the resistance decrease till the prescribed time DELTAT by a timer is calculated by an integration circuit 9 and transmitted to a welding current control circuit 8 as the correct setting quantity. The control circuit 8 gives instructions on a correction current value DELTAI to a welding current regulator 3 to finish the welding after the lapse of the prescribed time. Accordingly, the satisfactory resistance welding is performed in the prescribed time at all times regardless of changes of welding materials, a surface condition and the number of laminations.

Title: Dust prevention in tunneling method
Inventor: YAMAGUCHI YOSHIAKI
IPC: E21F5/02
Filed: 1988-08-11
Abstract: PURPOSE:To prevent any muddiness from occurring and keep off a drop in the conveyance efficiency of earth and sand as well as to stave off wear in a cutting tool by excavating a tunnel as spraying air bubbles of 10-20 times in expansion ratio to the periphery of a face or a breaking cutter against this face. CONSTITUTION:A bubbler 4 provided with a bubble discharge pipe 5 and a spray nozzle 6 is set up on a cover 1f of an excavator 1, and it is connected to a pump 8 to which a compressor 7 and a tank 9 stored with a frother aqueous solution are connected. At the time of tunneling, a frother quantity and an air quantity are controlled, expanding the frother to an expansion ratio of 10-20 times with the bubbler 4, and air bubbles are scattered toward a face in and around a cutter bit 1a from the nozzle 6. With this operation, dust is adsorbed to the surface owing to the adsorption effect of bubbles and, what is more, the sticking of dust mixed bubbles to a conveyor 1e is eliminated by a sticking preventive effect of the bubbles, thus wear in the bit 1a and other cutting tools is preventable.

Title: Information equipment
Inventor: YOKOZAWA YUKIO
IPC: G04G5/00
Filed: 1990-07-26
Abstract: PURPOSE:To obtain accurate time information which is always corrected automatically by calculating Greenwich Mean Time(GMT) information from information about receiving time, and correcting an indicated time according to the time information. CONSTITUTION:A wireless receiving circuit 11 converts the input signal of an antenna 10 into a digital signal and then a decoding circuit 12 corrects error and provides time information to a control circuit 13. The circuit 13 calculates GMT information from the time information since a time difference between the time information and GMT is included as information in the signal received. For example, in the case of a signal from a Tokyo service station, time information of AM 10:08:05:00 and information indicating a time difference of +8:00:00 between the time information and GMT are obtained and then AM02:08:05:00 is obtained as an indication of GMT. Then the circuit 13 sets the result on a timer circuit 16 according to the content of a GMT information storage circuit 17. The time indicated is further corrected by a correction information storage circuit 18 in which time information required by a user and information about the difference between the time indicated and GMT are stored and an indicator 14 indicates the corrected time information.
