Title: Level difference eliminator for wheelchair
Inventor: SEKI KEIMEI
IPC: B66F7/06
Filed: 2000-08-02
Abstract: PROBLEM TO BE SOLVED: To provide a level difference eliminator that functions also as a wheelchair lift, has no drive sources in itself and is usable as a trestle for a wheelchair because of lightness and compactness, and that is easily usable for many purposes of reasonably eliminating inconveniences that a lower limb-handicapped person who uses a wheelchair encounters in everyday activities. SOLUTION: Two parallel friction rollers are journaled on a platform on which a wheelchair is mounted, to support the driving wheels of the wheelchair. The rotation speed of the friction rollers is reduced by a reduction gear, and preferably, a reduction gear including a worm wheel to actuate a lifting and lowering mechanism for the platform. The lifting and lowering mechanism is suitably a pantograph mechanism.

Title: Method and apparatus for treating waste from power plant
Inventor: NOZAWA SHIGERU
IPC: C04B28/12
Filed: 2000-08-04
Abstract: PROBLEM TO BE SOLVED: To discharge no waste from a power plant to the outside without taking in waste or lime to the power plant from another place by effectively using the waste to be discharged from a power plant. SOLUTION: The waste from the coal-burning thermal power plant can be insolubilized by adding water to anhydrous or hemi-hydrated gypsum described-later and lime, mixing/kneading them, in a solidifying machine 16 and solidifying the mixture. The anhydrous or hemi-hydrated gypsum is obtained by heat-treating coal ash, which is discharged from a coal-burning boiler 1 for the power plant, and gypsum dihydrate is discharged from a flue gas desulfurization apparatus 3 for treating sulfur oxides in the exhaust gas from the boiler 1, in a calcination unit 9. The lime is obtained by calcining shells which are stuck to the equipment of the thermal power plant including a cooling water intake 6, in another calcination unit 12. The coal ash is melted in an ash melting furnace 19 by using waste oil discharged from the power plant as a part of the raw material and is hardened in the case of using a treating method other than the above method. When the lime is burned instead of the above method, toxic materials generating when burned can be reduced in volume by arranging a dioxin-removable catalyst unit 13 on the downstream of the unit 12.

Title: Wet clutch and clutch plate for wet clutch
Inventor: IRITANI MASANORI
IPC: F16D69/00
Filed: 2000-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a wet clutch for efficiently cooling heat generation due to friction of a clutch plate and the clutch plate for the wet clutch. SOLUTION: Oil grooves 19A and 19B are provided on a clutch plate assembly 16 side having higher heat conductivity than a friction material 26. Heat of the clutch plate assembly 16 becoming a higher temperature than that of a core plate 24 of a friction plate 22 is efficiently transferred to lubricating oil. Namely, the temperatures of friction surfaces 18B and 21B opposed to the friction plate 22 in the pate assembly 16 are effectively and adequately cooled in the clutch plate assembly and thereby temperature elevation on the friction surfaces 18B and 21B can be suppressed.  Since the oil grooves 19A and 19B are formed within the clutch plate assembly 16 without being formed on a surface opposed to a clutch plate of a friction material as in a conventional way, frictional heat load of the friction material for the clutch plate assembly 16 can be increased and transmission torque is improved when the friction surface 18B and 21B are in pressure contact with the friction plate 22.
