Title: Water feeding device equipped with leak protective means
Inventor: NISHIUCHI MASAYASU
IPC: F24H1/10
Filed: 1985-01-16
Abstract: PURPOSE:To enable to maintain an appliance at safe state by a structure wherein the leak of fluid from a liquid controlling means provided in a feed water passage is escaped through a discharge passage. CONSTITUTION:When liquid leaks across a sealed portion 7, the leaked liquid flows along a motor shaft 8 and collected by a dripping plate 9 through a leak protective casing 10 to a portion, at which a discharge passage 11 is provided, in order to flow through the discharge passage out of the casing. In this case, the leaked liquid is mixed with sodium chloride stored in a sodium chloride tank arranged in the midway of the discharge passage and, after that, accumulated in a leakage tank 13. Two electrodes are protruded in the leakage tank, resulting in sounding a buzzer 14 when the leaked water accumulates in the leakage tank so as to announce the leakage and at the same time abnormally heating a high limit switch assembled in a water feeding appliance by a nichrome coil 15 in order to stop the appliance safely. Thus, the replacement time of the sealed portion is made clear and at the same time the corrosion due to the humidity developed by the water leaked across the sealed portion is prevented from occurring. In addition, the capability for stopping the appliance safely with low cost enables to expect the improvement of maintenance and inspection.

Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To obtain a structural material having high strength and reliability by forcedly cooling a kneaded material at the time when the kneaded material containing an aggregate and a binder starts to change from a pasty state to a lumpy state. SOLUTION: Coke powder, artificial graphite powder, natural graphite powder, carbon black or the like is used as an aggregate, and tar pitch, coal tar or the like is used as a binder. The suitable weight ratio of the binder to the aggregate is 60-40:40-60. The aggregate having an average particle size of <=30 μm is preferably used. It is preferable that the aggregate and binder are kneaded at 200-290 deg.C using a double-arm type kneader and the kneaded material is cooled at the point of time when the kneaded material starts to change from a pasty state to a lumpy state by spraying water to it. The kneaded material is pulverized so as to make the average particle diameter 20-30 μm.  A carbon material suitable for various sliding materials is obtained by molding the powder obtained by the pulverization under a molding pressure of 29.4-137.2 MPa using a pressing machine or the like to form a block-shaped green body and then firing the obtained green body in a reducing atmosphere at 800-1,000 deg.C for 300-500 hrs.

Title: Underground tunnel system for traveling train
Inventor: MAKINO TOSHIAKI
IPC: E21F1/00
Filed: 1993-01-19
Abstract: PURPOSE:To reduce a braking distance of a train stopping in an emergency without increase of the running resistance due to the air when the train is running at a usual speed in an underground tunnel. CONSTITUTION:The resistance of a running train owing to the air can be reduced by passing the compressed air in front of the train in the underground tunnel 1, which is brought about by the traveling freight train 6a, 6b, through a bypass way 8 to the backward way of the train, by the opened air cut-off valves 10a, 10b. When a preceding freight train 6a stops and the distance between the train 6a and the subsequent freight train 6b decreases shorter than the safe distance between trains, the air cut-off valves 10a, 10b attached at the front and rear sides of an air suction or exhaust opening 9a between both freight trains 6a, 6b are closed to cut off the air flow through the bypass way 8 by a controller 12. In this way, the resistance of a running train owing to the air is increased and the increased air resistance acts to reduce the braking distance in an emergency.

Title: Estimation method for halftone picture of multivalued dither picture
Inventor: HIRATSUKA SEIICHIRO
IPC: H04N1/405
Filed: 1986-01-15
Abstract: PURPOSE:To satisfactorily estimate an original halftone picture by selecting an optimum scan aperture at every picture element through the prescribed arithmetic and employing the sum of multivalued picture element levels in the aperture. CONSTITUTION:The selection sequence of scan apertures is set D C B A, in that order. The aperture D is overlapped with a ternary dither picture, and ternary-coded with the sum 24 of the multivalued picture element levels in the aperture D as a mean picture element level. Then the ternary dither picture (w) and the ternary picture (z) are not the same pattern, and the aperture D is inappropriate for a selected aperture. If the aperture C is overlapped and ternary-coded with 26 obtained by multiplying the sum 13 of the multivalued picture element levels in the aperture C by a gain two as a mean picture element level, the aperture C is also inappropriate for a selected aperture. If the aperture B is overlapped and ternary- coded with 24 obtained by multiplying the sum 24 of the multivalued picture element levels in the aperture B by a gain two as the mean picture element level, the patterns of the multivalued dither picture (w) and the ternary picture (z) do not coincide with each other, and therefore the aperture A is selected. Where the sum of the multivalued picture element levels in the aperture A and the gain of the aperture A are 6 and 4, respectively, the estimated value of the picture comes to 24.
