Title: Heat pump hot water feeder
Inventor: IMABAYASHI SATOSHI
IPC: F24H1/00
Filed: 1983-01-20
Abstract: PURPOSE:To control the heating temperature automatically so that when the hot water feeding load is small in summer, the heating temperature is kept low while when the heating load is large in winter, the heating temperature is kept high, by a method wherein a high pressure detecting sensor of a high pressure heat pump and a water temperature detecting sensor for detecting the temperature of water in a hot water storage tank are provided thereby the operation of the heat pump is stopped by detecting the pressure of the heat pump and the heat pump is re-operated by detecting the temperature of water in the hot water storage tank. CONSTITUTION:In case where a main switch 17 is turned ON and when the temperature of water in the hot water storage tank 6 is low, a contact 13 of the water temperature detecting sensor is in a closed condition and as the pressure of the heat pump is sufficiently low, a contact 12' of the sensor is also in a closed condition so that a relay 14 is energized while contacts 15 and 16 are closed and so a blower 5' is energized to start the operation of the heat pump. As the temperature of water in the hot water storage tank 6 elevates, the pressure of the heat pump increases and when the pressure of the heat pump reaches a set value of the high pressure detecting sensor, the contact 12' of the sensor is opened to deenergize the relay 14. Therefore, the contacts 15 and 16 are opened to start the operations of the compressor 1' and the blower 5' and the operation of the heat pump is stopped to thereby complete the heating operation. In this case, since the set value of the pressure detecting sensor is made constant, the water in the hot water storage tank is heated to a high temperature when the open air temperature is low in winter while the water is heated to a low temperature when the ambient temperature is high in summer.

Abstract: PROBLEM TO BE SOLVED: To improve the durability of a catalyst by arranging the catalyst in the range where the cooling water fed from a mixing section into an exhaust pipe and atomized flows back by means of the exhaust gas pressure wave reflected on a volume section in the exhaust pipe on the upstream side than the mixing section. SOLUTION: The cooling water pumped up from the outside of a ship cools an engine 11, then it is fed to a cooling water jacket 40 to cool the periphery of a catalyst 30 and an exhaust pipe 20. The downstream end of the cooling water jacket 40 is opened in the exhaust pipe 20 to form a mixing section 91 for feeding the cooling water into the exhaust pipe 20 and mixing it with exhaust gas. The mixed cooling water is atomized by exhaust gas heat and flows to the downstream side of the exhaust pipe 20, and the atomized cooling water intermittently flows back to the upstream side by means of the positive pressure of the exhaust gas pressure wave reflected on a throttle 25d.  Since the catalyst 30 is arranged in the range where the backflow reaches, it is stuck with the cooling water and effectively cooled, and it is prevented from being cooled to an abnormal temperature to impair purifying performance because the cooling water flows back intermittently.

Filed: 1995-01-24
Abstract: PURPOSE: To provide a sliding member having excellent wear resistance, a low property to attack a mating member and excellent sulfide corrosion resistance. CONSTITUTION: This sliding member is obtd. by mixing hard particles consisting of 5 to 40wt.% FeMo or FeCr having an average grain size of <=50μm with a copper alloy contg. at least zinc in an amount of 15 to 45wt.% and thermally spraying this mixture with a high-velocity oxygen flame onto the sliding part surface of a base material, thereby forming a thermally sprayed layer thereon. The thermally sprayed particles fly at a high velocity from a thermally spraying nozzle and the evaporation of the zinc of the copper alloy forming the matrix of the thermally sprayed layer is prevented as far as possible and, therefore, nearly the same compsn. as the compsn. of the thermally sprayed layer is assured for the compsn. of the copper alloy powder before the thermally spraying and the sulfide corrosion resistance of the thermally sprayed layer is improved.  The m.p. of the copper alloy forming the matrix of the thermally sprayed layer is in a range of 900 to 1000 deg.C and the thermally sprayed layer has the excellent seizure resistance. Further, this thermally sprayed layer is formed by dispersing the hard particles into the copper alloy which is the matrix and, therefore, the sliding member has the excellent wear resistance and the low attackability to the mating member.
