Title: Guide vane of pump hydraulic turbine and its manufacture
Inventor: TANAKA YUJI
IPC: F03B3/18
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent the interference between a stay vane and a guide vane in an operating point having a large flow rate by rotating and moving the blade of the guide vane of a pump hydraulic turbine. SOLUTION: An axial center of a shaft 2 is provided so as to be on the outside of the form of a blade 1, and when a guide vane is rotated according to operating state, the blade 1 is not only rotated but also moved. Thus, the space L between the stay vane-side blade end of the blade 1 and the guide vane-side blade end of a stay vane 4 is minimized. For the flowing state at this time, the flowing-out direction of the water flow from the blade 1 is moved since the blade 1 is moved in the guide vane arrangement direction, and the slip stream of the guide vane never reaches the negative pressure surface 4S of the stay vane 4. Thus, since the slip stream of the guide vane is never interfered with the boundary layer of the negative pressure surface 4S, the pump efficiency can be improved without increasing the loss, and a high pump efficiency can be kept even in a large flow rate.

Abstract: PROBLEM TO BE SOLVED: To improve the operability while realizing the quick acceleration and quick deceleration so as to provide the speed expected by a worker quickly by simultaneously operating both of a hydraulic pump and a hydraulic motor of a hydraulic continuous transmission in relation to the target velocity ratio indicated by a traveling operation lever. SOLUTION: When a velocity ratio indicating lever 1120 is operated by a worker, the operated variable is detected by a position sensor 120a, and the detecting signal is output to a controller 100. This controller 100 obtains the target speed of a traveling vehicle on the basis of the input value while using the relational expression between the input value and the target value divided to plural areas for change. Operating speed of the velocity ratio indicating lever is computed on the basis of the input value at this stage, and a correction value obtained by multiplying the operation speed by a coefficient (k) is output. A value obtained by adding the correction value to the input value is set as a new input value, and the target speed is computed on this new input value.  With this structure, a hydraulic pump 22 and a hydraulic motor 23 of a hydraulic continuous transmission(HST) 21 can be operated at the same time.

Title: Nonflying snow-melting agent and production thereof
Inventor: TANIZAKI TAKESHI
IPC: C09K3/18
Filed: 1988-12-08
Abstract: PURPOSE:To prepare a nonflying snow-melting agent capable of being uniformly sprayed and giving desired nonflying and snow-melting effects as it looks black as a whole by mixing stoker ash ground to about the same particle size as that of EP ash, the EP ash and a binder and heat-drying the resulting mixture. CONSTITUTION:A stoker ash produced in various boilers is heat-dried, ground, and adjusted to about the same particle size as that of EP ash collected by an electrostatic precipitation in a smoke-exhausting route from the boiler stoker. The treated stoker ash and the EP ash are mixed with a binder (e.g. a waste molasses, a pulp waste soln., or an alcohol waste soln.) and the mixture is heat-dried to give a nonflying snow-melting agent. The resulting agent can be uniformly sprayed and gives desired nonflying and snow-melting effects since the fine powder of the EP ash, being black colored and having a snow- melting ability by nature, is attached in such a manner that it adsorbs the binder, thus causing the agent to look black as a whole.
