A gas liquid centrifugal separator includes a cylindrical vessel having an axis extending in a vertical direction, an exhaust port in a top wall of the vessel which discharges gas separated from a liquid-gas mixture, a drainage port provided in a bottom wall of the vessel which discharges liquid separated from the liquid-gas mixture, and an introducing port in a peripheral wall of the vessel which introduces the mixture into the vessel. Gas-liquid separation is conducted by an inverted conical liquid surface formed in an upper separating chamber of the vessel as a result of the mixture traveling circumferentially along an inner peripheral surface of the vessel.

A method of fabricating a back surface point contact silicon solar cell having p-doped regions and n-doped regions on the same side by forming a passivating layer on a surface of the cell having opened windows at the p-doped regions and the n-doped regions, by depositing and patterning a first metal layer on the passivating layer in such a way that the first metal layer comes into contact with the p-doped regions and the n-doped regions, by depositing a first insulator layer of inorganic material on the first metal layer, by etching and patterning the first insulator layer in such a way that the insulator layer has opened windows at, at least one of the p-doped regions and the n-doped regions, by depositing a second insulator layer of organic material on the first insulator layer, by etching and patterning the second insulator layer in such a way that the insulator layer has opened windows at the one of the p-doped regions and the n-doped regions, by curing the second insulator layer by heating at a predetermined temperature for a predetermined time, and depositing a second metal layer on the second insulator layer of organic material in such a way that the second metal layer comes into contact with the one of the p-doped regions and the n-doped regions. With this, the cell surface to be soldered onto a metallized substrate is well planarized and even to ensure sufficient conductibility, with less voids and less solder fatigue.

A drive device for a power working vehicle has a transmission case for a hydrostatic pressure type continuously variable transmission which includes a hydraulic pump and a hydraulic motor, the case having a narrow portion and a wide portion with a step being formed on one side of the transmission case. The hydrostatic pressure type continuously variable transmission is mounted to the narrow portion, so that it is accommodated within the height of the step. A differential is provided at the wide portion for differentially operating left and right axles, and a reducing gear mechanism extends from the narrow portion to the wide portion for transmitting an output from the continuously variable transmission to the differential through a multi-stage reduction. Thus, the output from the continuously variable transmission can be transmitted to the left and right axles through a reduction at a plurality of stages, and the structure of the drive device for the power working vehicle may be made simpler and more compact.

A ball and piston valve for controlling the flow of hydraulic fluid to a motive means have the ball and piston spring biased in opposing directions and with both initially subject to a first hydraulic fluid pressure that allows the springs to cause the ball to be unseated from its seat whereby fluid is directed to a fluid tank and wherein the ball is of sufficiently larger diameter than the piston that upon an increase in fluid pressure the ball is seated and remains seated when the pressure drops to the first hydraulic fluid pressure whereby the motive means to which the fluid is directed when the ball is seated does not have a sudden lurch upon a subsequent increase in pressure.

A hydrostatic continuously variable transmission includes a closed hydraulic circuit comprising a hydraulic pump, a hydraulic motor, and an oil supply passage connected between the hydraulic pump and the hydraulic motor. The hydraulic pump selectively generates a first oil pressure lower than a first predetermined pressure level, a second slowly-changing oil pressure higher than the first predetermined pressure level when the transmission is in normal operation, and a third rapidly-changing oil pressure higher than a second predetermined pressure level higher than the first predetermined pressure level when the transmission starts to operate. The transmission also includes a first pressure-responsive valve for connecting the oil supply passage to the oil tank in response to the first oil pressure applied through the oil supply passage, and disconnecting the oil supply passage from the oil tank in response to the second oil pressure applied through the oil supply passage, and a second pressure-responsive valve for connecting the oil supply passage to the oil tank in response to the third oil pressure applied through the oil supply passage, and disconnecting the oil supply passage from the oil tank in response to the second oil pressure applied through the oil supply passage.

摘要:
Energy supplying system in which effective use of waste heat from a solar power generator and an engine power generator. Electric power generated by an SLCS (sunlight cogeneration system) 1 and an EGCS (engine cogeneration system) 2 is supplied to a power consuming apparatus while its relevant waste or exhausted heat is transferred to a heat consuming apparatus 3. The power generated by the SLCS 1 varies depending on the local climate and is monitored with a power meter 6 or a power monitor apparatus 7. When the power from the SLCS 1 is declined, it is compensated by increasing the power output of the EGCS 2. Since the total power generated by the SLCS 1 and the EGCS 2 is maintained constant and the total waste heat released from the SLCS1 and the EGCS 2 is relatively stable, the heat consuming apparatus 3 as well as an power consuming apparatus 5 are steadily energized.
摘要:
An unactivated, poorly activatable hydrogen storage component and an activated hydrogen storage component are mixed to prepare a hydrogen storage material. When the hydrogen storage material is activated, the poorly activatable hydrogen storage component is converted to a hydrogen storable state in a remarkably short time. The poorly activatable hydrogen storage component may be a V—Cr—Ti hydrogen storage alloy having a body-centered cubic (BCC) crystal structure. The activated hydrogen storage component preferably is MgHx (0.1≦x≦2) doped with a nanoparticle of at least one atom selected from the group of Ni, Fe, Ti, Mn, and V.
