Title: Method and device for constructing underground structure
Inventor: UEMURA KOICHI
IPC: E21D9/04
Filed: 1992-04-17
Abstract: PURPOSE:To make it possible to construct a wide underground structure without interrupting upper ground traffic and especially either eliminate an arrival shaft or accept even a very small-sized arrival shaft and jacking an underground structure from both sides of a planned tunnel and unit them in the center of the planned tunnel when jacking and constructing longitudinally a large-sized underground structure at a position at which the earth coverage of the underground structure is shallow. CONSTITUTION:A friction cutter plate 6 is installed to the top of loop pipes 5 whose cross section is box-shaped. To comply with a required position of the planned tunnel, the pipes 5 are laid out in parallel so as to match with the cross section and connected one by one from a launching pit 9 and press- fitted underground by a required length. The front end of the underground structure 9 is opposed to and brought near to the rear end of the loop steel pipe 5. The rear end of the loop steel pipe 5 is cut by a proper length while the friction cutter plate 6 is left over underground. Then, the friction cutter plate 6 is used to shield-propel the underground structure 9 by the length equivalent to the eliminated portion.

Filed: 1986-05-29
Abstract: PURPOSE:To eliminate a fear of a corrugate fin being thermally softened and buckling deformation occurring in a heating process in a soldering furnace, by a method Wherein the fin pitch of the corrugate fin in a lamination type heat exchanger is partially decreased. CONSTITUTION:A corrugate fin 2 is formed such that a very thin aluminium sheet is bent in a corrugating shape with a pitch width of about 4.0mm, and has an area approximately equal to the plane area of a ventilation flue C for heat exchange between adjoining flat tubes 1. A length in the direction of the height of the flat tube 1 is about 200-250mm, and the length of a lower end part D has a pitch width which is reduced to approximately 1.5mm throughout a length of approximately 10mm. When an evaporator having said corrugate fin is assembled for soldering, in case the corrugate fin is heated approximately to a thermosoftening temperature in a state to be compressed by a jig for assembly, the corrugate fin 2 is nipped between the adjoining flat tubes 1 to exert a buckling action force thereon. However, since the lower end side part D has pressure resistant structure, the corrugate fin can be prohibited against buckling.

Title: Horizontal deflection circuit
Inventor: EBIHARA SHOJI
IPC: H04N3/16
Filed: 1987-05-20
Abstract: PURPOSE:To efficiently execute a power source supplying and to reduce power comsumption by respectively supplying a power source from the power source to a transistor TR for a horizontal drive at the time of oscillating activating of a horizontal oscillating circuit and from a rectificating circuit after the oscillating activating. CONSTITUTION:At the time of the oscillating activating of a horizontal oscillating circuit 3, since a TR4 for a horizontal drive is not operated yet, a current from a power source terminal 1 is supplied through a resistance 6, a resistance 13, a Zener diode 12 and a diode 14 to the circuit 3. After the oscillating activating of the circuit 3, the TR4 is operated and a TR7 for a horizontal output is operated, too. Thus, through a transformer 8, a direct current voltage is generated from a rectificating circuit 9 and supplied through a diode 15 to the circuit 3. At this time, since the collector voltage of the TR4 is lower than the power sourve voltage of the circuit 3, the diode 14 comes to be a reverse bias and a current to flow from the circuit 9 to the circuit 3 is prevented from flow to the TR4.

Title: Method and system for locating ground fault on power line
Inventor: KANAI MINORU
IPC: H02H3/40
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To locate a ground fault on a power line quickly by calculating the distance to a ground fault point from a detecting means based on system constants for calculation when a decision is made that a detected electric waveform matches a calculated electric waveform. SOLUTION: A decision is made that a ground fault occurred on the distribution line of slave stations 10, 11 having phase inversion by locating the point on the distribution line where the phase of zero-phase current is inverted. Waveform of the zero-phase current is then calculated at the fixing point of a sensor 6 adjacent to the faulty section and the ground fault point, the ground fault resistance and various system constants are updated repeatedly until a decision is made that a measured waveform matches a calculated waveform. When a decision is made that the waveforms match each other, the distance to the ground fault point is calculated from the line reactance and the distance from the fixing point of the sensor 6 to the ground fault point is outputted to a display section. According to the arrangement, ground fault can be located surely using a relatively small number of sensors regardless of variation in the system configuration or the ground fault resistance.

Inventor: SAWAGUCHI HIDEKI
IPC: G11B20/12
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of data decoding in a decoding processing in a maximum likelihood sequence detection by applying a processing to be able to detect and correct that specifice coding erroneous phenomena having preliminarily set prescribed coding erroneous patterns are generated till prescribed numbers and recording an error correcting code dividedly or en bloc at a prescribed recording position corresponding to a recording code series block. SOLUTION: Decoded code series 311 decoded in a maximum likelihood sequence decoder 310 are inputted or directly inputted to a first error correcting and coding circuit 304 without logically changing code orders. This processing only continuously applies a fixed processing to respective codes without replacing or exchanging the code orders of the decoded code series 311. Consequently, since the processing is possible to correspond to a code erroneous syndrome one to one, the erroneous syndrome is never dispersed on the code series before and after the processing. This processing can be executed by adopting a constitution in which the first error correcting and coding circuit 304 is connected to the maximum likelihood sequence decoder 310 being a composite means.

Filed: 1987-05-25
Abstract: PURPOSE:To decrease the number of nodes and to shorten the retrieving time of information by integrating the nodes having a digit number '1' to their slave nodes and adding the least significant code of division information to each leaf as the division information to a master node. CONSTITUTION:A 4-split area only being an object is shown in a tree structure and at the same time the nodes having the digit number '1' are deleted and integrated to their slave nodes. Thus the number of nodes can be extremely decreased compared with a normal 4-split tree structure. Furthermore, the leaf parts are controlled by the extension codes for reduction of the number of leaves. Then the division information shown in the permutation data so that the hierarchical properties deteriorated in the production process of the tree structure can be compensated. At the same time, the information can be effectively retrieved on the tree structure.

Filed: 1988-05-25
Abstract: PURPOSE:To decrease necessary medium quantity and to attain the recording of high density at >= two type speeds by switching a signal system number, which is simultaneously recorded or reproduced, to be M-fold (M is >= Z positive integer number) and causing a tape speed to be a speed which is slightly faster than the M-fold speed. CONSTITUTION:Magnetic heads A-D and E-H are provided in a rotary drum and the signals of four systems can be recorded or reproduced. When the signal system number to be simultaneously recorded or reproduced is switched to be M-fold by a prescribed mode control means, a speed Vt of a tape 2 is switched to the speed which is slightly faster than the M-fold speed. Thus, since a tape speed ratio and a recording system number are varied slightly, the difference of track pitches, which are obtained at the different tape speeds, is decreased and the medium using quantity is made minimum. Then, the recording of the high density can be executed.

Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce load fluctuation accompanied by the fuel change from oil to gas in a gas turbine fuel oil purge system, by reducing an amount of oil remaining in the inside of a piping, which is to be delivered to the inside of a combustor. SOLUTION: Fuel oil is passed through a flow regulating valve 11, a piping 12, a header 13, a piping 14, a sealing connection pipe 32 and a piping 33, ejected from a fuel nozzle 20b to the inside of a combustor 25 and burnt. In the case that fuel is changed from oil to gas, the flow regulating valve 11 is closed, however oil remains in the inside of the piping, therefore, opening/closing valves 31, 24 are opened, and air 41 is passed through a purge air system piping 30, the sealing connection piping 32 and the piping 33, and ejected from the fuel nozzle 20b to the inside of the combustor 25. Hereby, the ejection of the residual oil in the piping 33 and a reverse flow of combustion gas can be sealed. Air 41 is led to flow into the pipings 14, 12, led to flow out from a drain valve piping 23, and discharges residual oil in these pipings to the outside of the system.  The residual oil delivered to the inside of the combustor 25 remains by a part of the piping 33 only, therefore load fluctuation by the residual oil can be reduced.
