Title: Method for reforming coal ash
Inventor: HARADA HIKARI
IPC: B09B5/00
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To lessen ignition loss and to increase fineness (specific surface area) by making coal ashes finer, then agitating and shaking the ashes in a solvent mixture composed of an org. solvent and water, thereby separating and removing the carbon-component in the coal ashes into an org. phase. SOLUTION: The coal ashes, the water and balls for pulverization are put into a pot mill. At this time, the carbon content of a product is lower as the ratio of the coal ashes to the water is smaller at the time of milling and, therefore, the ratio is specified preferably to 0.3 to 0.2. While the sizes of the balls for pulverization are not particularly limited, the balls of, for example, 20 mm in diameter are used. After milling is executed for, for example, 6 hours, the resulted coal ash slurry is taken out and is transferred into a shaking and mixing vessel. The water is added up to the marked line in the vessel and further, petroleum (kerosene), etc., as the org. solvent are added thereto and after the mixture is shaken and mixed for, for example, 5 minutes, the mixture is rested still to separate the water phase and the org. phase.  The carbon-content in the coal ashes is extracted and separated into the org. phase.

Title: Shift driver of continuously variable transmission for vehicle
Inventor: KITA YASUO
IPC: B60W10/10
Filed: 1990-11-30
Abstract: PURPOSE:To make improvements in starting characteristics and economical efficiency by negative-feedback-controlling the displacement volume of an input side hydraulic pump/motor so as to keep the extent of effective differential pressure in a hydrostatic transmission system to the setting pressure conformed to an accelerator angle. CONSTITUTION:When an accelerator 11 is operated at time of starting, a throttle is interlocked with it and varied into a step form. In this case, displacement volume of an input side hydraulic pump/motor 1 gets varying by means of negative-feedback control without waiting an up of engine speed so as to have effective differential pressure kept in the setting value conformed to the accelerator operated variable. With this constitution, when an output side hydraulic pump/motor 2 gets rotating, the displacement volume of the input side hydraulic pump/motor 1 is further increased in order to compensate a drop in the displacement volume due to the swallowing of pressure fluid. This action occurs in a linkage manner, and the displacement volume of the input side hydraulic pump/motor 1 is increased in a moment the accelerator 11 is operated, and when the effective differential pressure is stabilized and maintained, the effective differential pressure is proportioned to acceleration of a car body, thus stable and effective tractive force is securable.
