Title: On-column-type electric conductivity detector for dynamic electricity separation by microcolumn
Inventor: ZARE RICHARD N
IPC: G01N27/60
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To provide an improved electrical detector used in a dynamic electricity separation system by a highly sensitive microcolumn capable of detecting chemical species, which change in electric conductivity in an analysis solution of a concentration lower than 10-7mol/1. SOLUTION: Sensor electrodes 21 and 22 are positioned directly above the wall part of a column in contact with the flow of substances 18 and 19 to be analyzed or directly adjacent to the wall part. Therefore, no dead volume occurs in the flowing movement of a fluid or no sectional area increases. This electric conductivity detector is a single on-column-type electrode and positioned directly adjacent to the outlet end part of the column. This electric conductivity detector comprises a pair of or more on-column-type electrodes. As these paired electrodes are positioned straight across the column in locations facing each other, an potential between the electrodes and an electrochemical reaction accompanying to it are suppressed to a minimum.

Title: Elevator car sound-insulating method and elevator device
Inventor: YAJIMA KOJI
IPC: B66B13/30
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To provide an elevator device suitable for very increased speed. SOLUTION: A pole face 21 of an electromagnet is disposed around the opening of a car 1 closed by a door 5 or at the edge part of the door and the opening and closing of the door is controlled by a controller. When the door is closed, the electromagnet is energized and, when opened, it is deenergized. By this, when the door is closed, namely, when an elevator is moved up and down, the area around the opening part and the door forming an access to the elevator car are fitted closely to each other by the electromagnet so as to eliminate a clearance. Thus, noise entry from the outside into the car is prevented even when the elevator is operated at a very high speed. When the door is opened, i.e., at the time of landing of the elevator, the door can be opened and closed freely because the electromagnet is deenergized.

Title: Method for calcining molded body of ash obtained by incinerating sludge
Inventor: TAKAHASHI SHIRO
IPC: B09B3/00
Filed: 1988-12-20
Abstract: PURPOSE:To enhance the compressive strength and bending strength of a molded body of ash obtd. by incinerating sludge and to reduce the rate of water absorption by rapidly raising the temp. of a furnace until the surface temp. of the molded body reaches a prescribed temp. below the softening point of the ash and by slowly raising the temp. of the furnace to the softening point of the ash.
