Title: Controller of automatic carriage system
Inventor: TAKAYAMA MASAYUKI
IPC: B60L13/00
Filed: 1984-04-04
Abstract: PURPOSE:To control the speed and to detect the position of a carriage train by power supply trolley wires and a signal trolley wire by providing detecting means for detecting the polarity of a power supply line in the train. CONSTITUTION:When a carriage train 9 moves to a signal trolley 9e, a current flows to a photocoupler 29e for detecting the position of the train, and the signal is input to a carriage train service controller 26. If a forward electromagnetic contactor 33e is closed at this time, a current flows to a forward signal receiving photocoupler 20, and a forward command is input to a speed controller 13. On the other hand, if a low speed command switch 27e is closed, a current flowed to the trolley 6e is cut off. Accordingly a low speed command receiving photocoupler 22 becomes OFF, and a slow speed command is input to the controller 13. If the contactor 33e is opened, the power of a power supply trolley wire 4 is interrupted, and an electromagnetic brake is operated to stop the train 9.

Title: Optical sensor
Inventor: ASAI YUJI
IPC: G01R33/032
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain an optical sensor in which the fluctuation of the value of light quantity loss caused by temperature fluctuation is small and which can be manufactured at a low cost. SOLUTION: An optical sensor is constituted in such a way that upper and lower sensor bases 1 and 2 are formed by molding a resin, such as the liquid crystal polymer, etc., the coefficient of thermal expansion of which largely varies between the flowing direction and its perpendicular direction and an optical lens 4, a polarizer 6, an optical element 7, an analyzer 8, and an optical lens 9 are successively arranged between the bases 1 and 2. In addition, optical fibers 12 and 13 are arranged on both sides. When a resin having a coefficient of thermal expansion of <=5×10-6/ deg.C in the flowing direction is used, the variation in dimension of the sensor in the direction of its optical axis can be reduced and the fluctuation of the value of light quantity loss caused by temperature fluctuation becomes smaller.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To enhance the responsiveness for determining whether it is a liquid or a gas phase, by providing resistance temperature sensor type liquid level detectors incorporated in an LOX tank or an LH2 tank in a rocket. SOLUTION: In a resistance sensor type liquid lever detector composed of a sensor part and a signal conditioner for feeding a current to the sensor part, a variation in resistance of the sensor part in the form of a voltage, conditions 3, 4 of gas-liquid or liquid-gas in a low temperature container are determined so as to detect a liquid level.

Meanwhile, upon determination of the liquid-gas condition 4, a large degree of current 2 is fed as conventionally made. Upon penetration of a liquid into the sensor, the heating lave is retrained, thereby it is possible to enhance the responsiveness of determination of a gas-liquid condition.

Filed: 1990-03-16
Abstract: PURPOSE:To secure the abrasion resistance and rigidity of a cylinder bore by composite-reinforcing the surface part of the cylinder bore by ceramic short fibers and composite-reinforcing the upper peripheral part by the inorganic long fibers oriented in the peripheral direction. CONSTITUTION:The surface part of a cylinder bore 12 is composite-reinforced by ceramic short fibers 6, and at least the part on the periphery of an upper part is composite-reinforced by the inorganic long fibers 18 oriented in the peripheral direction. The ceramic short fiber 16 possesses the superior abrasion resistance improvement effect, and though the alumina - silica short fiber, alumina fiber, and inorganic long fiber 18 may be the arbitrary long fiber used in the manufacture of a composite material, the long fiber which possesses the high elasticity itself such as carbon fiber, carbonized silicate fiber, and alumina fiber is preferable.

Title: Heat accumulation type heat exchanger
Inventor: HIRAZAKURA NAOYUKI
IPC: F28D20/02
Filed: 1982-04-21
Abstract: PURPOSE:To make the effective use of a heat exchange operation for which switching between heat accumulation and heat radiation is frequently made, by a method wherein heat transfer pipes of the shell and tube type heat accumulating heat exchanger are arranged laterally and divided into an upper group and a lower group of which the upper heat pipe group is used for the accumulation of heat and the lower heat pipe group is used for the radiation of heat so that the accumulation of heat is performed in a place separated from the point where the radiation of heat is carried out. CONSTITUTION:In case where heat is accumulated, if a high temperature vapor is supplied through the heat transfer pipes 242 of the lower group, the specific gravity of molten salt as a heat accumulating material filled into horizontal tanks 21a and 21b becomes small as the temperatures in the tanks 21a and 21b increase so that the molten salt heated to a high temperature as a result of its heat exchange with the high temperature vapor moves upward and the low temperature molten salt which has not exchanged heat with the high temperature vapor at the upper parts of the tanks 21a and 21b moves downward. Accordingly, the heat exchange operation in the heat accumulator is promoted to a great degree. Further, in case where heat is radiated, an operating liquid and the high temperature molten salt exchange heat with each other and unlike at the time of heat accumulation, the low temperature molten salt moves downward while the high temperature molten salt moves upward in the tanks 21a and 21b during which the radiation of heat is performed. Accordingly, the operating liquid exchanges heat with the high temperature molten salt at all times.

CONSTITUTION:An auxiliary tank 3 is connected to the solar heat collector 1 installed on the roof of a building 2 through the communication pipes and a thermometer 15 for detecting the temperature of the hot water is attached to the auxiliary tank 3. When the temperature of the hot water in the auxiliary tank 3 reaches a predetermined value, an electromagnetic valve 16 is opened through the thermometer 15 so that the hot water is supplied into the hot water tank 4 through a pipe 12 due to the difference between the level P of the hot water in the auxiliary tank 3 and the level of the hot water at an outlet Q. At the same time, when the level of the hot water in the auxiliary tank 3 lowers, water is supplied into the auxiliary tank 3 additionally through a water supply pipe 10 whereby the temperature in the tank 3 is lowered and the electromagnetic valve 16 is closed through the thermometer 15. Thus, the hot water is kept stored in the hot water tank 4 by the repetition of the above mentioned operation and if necessary, the stored hot water may be further heated by an auxiliary heater 20 and is supplied from a hot water supply pipe 13 for diverse purposes.
