Title: Method for loading fine particle
Inventor: MIURA SATORU
IPC: B65B1/16
Filed: 1989-11-30
Abstract: PURPOSE:To load fine particles at a high speed with a high density as well as prevent the loaded fine particles from being pressed into a lump in a vessel by suppressing an increase in pressure outside the vessel so that difference in pressure from outside the vessel increases as a pressure inside the vessel rises. CONSTITUTION:A specific amount of toner reserved in a toner hopper 11 is dropped into a vessel through a fine particle supply line 12. At this time while an opening/closing valve 46 provided in a second decompression tube 41 is kept opened so that a pressure in a decompression case 20 is relatively high during an initial loading period when an opening/closing valve 13 is opened, a vacuum pump 44 is controlled so that the pressure in the decompression case 20 relatively rapidly rises immediately before loading is completed. As a result the pressure in the vessel when the opening/closing valve 13 is opened is a pressure higher than it used to be, so that the toner loaded in the vessel is free from being pressed into a lump even at an initial stage of the opening of the opening/closing valve 13 when difference in pressures between inside the vessel and outside the decompression case 20 is large.

Title: Continuously variable transmission for vehicle
Inventor: TANIGUCHI KATSUHIKO
IPC: F16H9/18
Filed: 1988-12-10
Abstract: PURPOSE:To increase efficiency by reducing pump capacity and compact a transmission by reducing the number of parts, by connecting a driven side pressure chamber and a regulating hydraulic pressure chamber to each other when the radius of rotation of a belt wrapped on a driven side pulley is less than a specified value and separating them from each other when it is more than a specified value. CONSTITUTION:The widths of grooves 24 and 38 for a drive side and a driven side pulleys 4 and 6 are increased and decreased by hydraulic pressure and the spring force of a compression spring 40, respectively, and the radius of rotation of a wrapped belt 8 is increased and decreased to very the ratio of transmission. When the radius of rotation r of the belt 8 is less than a specified value r1, a driven side hydraulic pressure chamber 36 and a regulating pressure chamber 66 are connected to each other by a hydraulic pressure chamber disconnecting and connecting means 86; when it is more than a specified value r1, they are separated from each other. In other words, at a transmission ratio in speed increasing where the radius r is less than a specified value r1, the driving torque transmitted by the belt 8 is reduced in inverse proportion to the speed increasing ratio and, therefore, hydraulic pressure supplied to the hydraulic pressure chamber 66 may be weak. Accordingly, even if a part of hydraulic pressure in the hydraulic pressure chamber 36 is fed to the hydraulic pressure chamber 66, hydraulic pressure in the hydraulic pressure chamber 36 will not be dropped and the belt 8 can be held sufficiently.
