Filed: 1989-02-23
Abstract: PURPOSE:To make easy infiltration of water possible by constructing an infiltration tank by alternating execution of ground excavation and assembling of ring bodies, and by installing a sedimentation tank thereon and a water- permeable pipe body. CONSTITUTION:A collecting pipe 15, communication with an aboveground collecting valve, is installed to a sedimentation tank 1. An infiltration tank 2 is made from liner plates 21 and crushed stones 27 and coarse sand 28 are provided therein and laid respectively in the upper layer and in the lower layer. The liner plate 21 is made from a water-permeable drain plate 22, which is superimposed over a corrugated plate 23 and is bent together toward the corrugated plate-side into circular arc, and weep holes 24 and a joining frame 26 are provided to the corrugated plate. To a filtering pipe, a band 31 for fixing the pipe to a floor board 11 and a filtering cloth 32 are provided. In installing the device, a water-permeable sheet is stretched over the natural ground. Then a ring is constructed of a number of the liner plates 21 that are assembled together, and the infiltration tank is installed by the inverted lining method. Thereby clogging and breakdown at the infiltration surface of the natural ground can be prevented.

Title: Continuous casting method for pipe
Inventor: ODA TEISHIROU
IPC: B22D11/00
Filed: 1980-04-07
Abstract: PURPOSE:To continuously cast a pipe without causing any repturing accident by disposing slits on the outside circumferential surface of a core and pouring melt between an outside mold and the core while supplying a lubricant into these slits. CONSTITUTION:Slits 5 of a predetermined width are disposed at predetermined intervals in a vertical direction on the outside circumferential surface of a continuously rotating water-cooled type hollow core 4. When molten steel 13 or the like is poured between a water-cooled outside mold 1 and the water-cooled core 4 while a lubricant 7 is being supplied into the slits 5, the molten steel 13 begins to solidify by being cooled from the inside and outside surface. At this time, the lubricant 7 descends in the slits 5, and contacts the inside surface of the metallic pipe under formation and further along with the rotating motion of the core 4, the lubricant 7 disperses circumferentially, and distributes uniformly and effectively between the inside surface of the metallic pipe and the outside circumferential surface of the core 4. This decreases the drawing force of the pipe and the driving force required for the rotation of the core 4, decreases the repturing accident of the pipe and increases operating stability.

Title: High-speed semiconductor device
Inventor: IMAMURA KENICHI
IPC: H01L29/73
Filed: 1986-03-04
Abstract: PURPOSE:To let the titled device have a double-frequency function, an exclusive NOR function and so on by a method wherein quantum wells are each provided in an emitter layer and a collector layer, a collector current is let have a peak to the prescribed collector-emitter voltage and the peak is variably adjusted by a base-emitter voltage. CONSTITUTION:Quantum wells QW are each provided in an N-type GaAs collector layer 3 and an N-type AlGaAs emitter layer 5. The well QW in the layer 5 consists of an AlxGa1-xAs (x=0-1) layer and a GaAs layer and the so-called tunneling phenomenon is generated. Therefore, when a base-emitter voltage VBE is set at a certain value, an emitter current IE abruptly flows and in the case of a value other than that, the current IE is remarkably decreased. Moreover, the well QW in the layer 3 at least consists of an AlAs layer and a GaAs layer and when a base-collector voltage VBC is set at a certain value, a base current IB is rapidly supplied and in the case of a value other than that, the current IB is rapidly decreased. Thereby, this device can be let have a double- frequency function, an exclusive NOR function and a many-valued memory function while maintaining a high-speed efficiency.

Filed: 1985-03-07
Abstract: PURPOSE:To make it possible to increase the reliability of a core bonding operation and to give a freedom to a core bonding process by a method wherein, after a ferrite core is inserted into an insulating case and assemblage is conducted, a bonding agent is injected into a bonding-agent leakage checking wall formed on the upper part of the insulating case, through a cut for injection of the bonding agent. CONSTITUTION:A bonding-agent leakage checking wall 11 on which a part of a ferrite core 2 is fitted is formed on the upper part of an insulating case 1, and a cut 12 for injection of a bonding agent is provided in said bonding-agent leakage checking wall 11. The ferrite core 2 is inserted into the insulating case 1 so that a part thereof is fitted on the bonding-agent leakage checking wall 11, and thereafter a bonding agent is injected from a bonding agent injection nozzle 3 through the cut 12 for injection of the bonding agent. Thereby the injected bonding agent 4 expands sufficiently into the clearance formed between the insulating case 1 and the ferrite core 2, thus enabling further reliable bonding.

Title: Distribution type tactile sensor
Inventor: KATANO TOMONORI
IPC: G01L1/22
Filed: 1990-02-28
Abstract: PURPOSE:To suppress the influence of temperature and to accurately measure a load by forming a Wheatstone bridge circuit of an active gauge and dummy strain gauges formed by connecting strain gauges for load detection and temperature compensation in series. CONSTITUTION:When a vertical load is placed on a pressure reception part 5, strain gauges 3A for load detection have large compressive strain, which is less than strain by temperature variation. Strain gauges 3C for temperature compensation which are provided at right angles to edges of a silicon plate 2, on the other hand, have a little strain to a load, but have tensile strain in the case of temperature variation. Therefore, when the gauges 3A and 3C are combined and connected in series, the strain quantities to the temperature variation can be canceled to obtain the active gauge. Further, the dummy strain gauges 3B are not strained with neither a load nor temperature, so the Wheatstone bridge circuit can be formed of the dummy strain gauges and active gauge, so variation with temperature is suppressed and the load can accurately be detected.

When the buffer 300 stops the transmission, a reset means 800 resets the value of the means 600 of the buffer 400 for each of all the input terminals corresponding to the same output terminal.

Filed: 1985-03-11
Abstract: PURPOSE:To prevent a deterioration of a picture quality in a boundary of a block by dividing a picture plane into plural blocks, disposing a means for selecting a signal processing of plural modes corresponding to a movement every block, and using a mode information of the block and the mode information of the block adjacent thereto to perform the signal processing. CONSTITUTION:In a weight circuit 5, with respect to picture elements (a), (b), (c), (d), a weight 1 is applied to an output of an auxiliary filter 1 and a weight 0 is applied to an output of an interpolating filter except therefor. Accordingly, the output of the weight circuit 5 obtains a signal corresponding to (A+B)/2 interpolated by the auxiliary filter 1. For the picture element (e), since interpolation is done by an average of a mode M1 and a mode M2, in the weight circuit 5, a signal is obtained by applying a weight of 1/2 to outputs of an interpolating filter 1, and an interpolating filter 2. Namely, corresponding to the mode information, in the weight circuit, the output signal of the interpolating filter is weighed and thereby an average signal of the mode information can be produced.
