Title: Measurement of large deformation
Inventor: HAYAKAWA YASUYUKI
IPC: G01B21/32
Filed: 1987-09-29
Abstract: PURPOSE:To determine large deformation of subsoil in a time sequence, by a method wherein a shape memory wire is inserted into a pipe, current flows through the wire to memorize the shape at the moment by heating and then, the wire is taken out of the pipe to be returned to the shape memorized. CONSTITUTION:A shape memory wire 3 is inserted into a pipe 2 buried into a hole 1 made by drilling or the like and current flows through the wire to heat it so that the shape is memorized at the moment above a certain temperature. Thereafter, the wire 3 is taken once out of the pipe 2 and heated in a measuring chamber or the like above 40 deg. again to be deformed to the shape previously memorized. The deformation is measured as initial value thereof. This operation is performed at a certain frequency to determine a large deformation of the subsoil in a time sequence.

IPC: G03G9/113
Filed: 1994-10-11
Abstract: PURPOSE: To prevent spending even in a high-speed copying machine, to maintain stable triboelectric chargeability over a long period of time and to improve durability by incorporating fine α-alumina powder into a coating resin layer. CONSTITUTION: Fine α-alumina powder is incorporated into a coating resin layer on the surface of a carrier. This α-alumina has α-crystal structure and is next to diamond in hardness. The Mohs hardness of the alumina is 9 and the alumina has such high electric insulating property as 1,015Ωcm volume resistivity. The fine α-alumina powder is, e.g. pulverized molten alumina or high purity alumina. At the time of stirring in a developing unit, the fine α-alumina powder dispersed in the coating resin layer of the resultant carrier polishes the surface of the carrier by the contact of the particles of the carrier with each other to prevent the spending of the carrier and stability of triboelectric charge is satisfactorily maintained over a long period of time.

Abstract: PURPOSE:To increase transmitted torque property without enlarging a device by housing a blade, which produces pressure according to the differential rotation of two shafts by means of viscous friction gained by moving a high- viscocity fluid to a space portion with the differential rotation of two shafts and forming a wedge-like protrusion on both end faces in a rotational direction thereof. CONSTITUTION:When relative rotation arises in between two shafts 15, 16, a blade 42 is given relative rotation to a housing 21. A high-viscocity fluid 44 filled in a pressure room 43 is thus forcibly moved in between two opposite faces at a flowing rate in accordance with a rotating speed difference, and inner pressure in proportion to the differential rotation of two shafts 15, 16 is produced in the pressure room 43 by the operation of viscous friction of the high-viscocity fluid 44, so that a piston 24 is pressed. At this time, however, wedge operation by a wedge portion 42A (42B) formed on a blade 42 increases pressure which is produced in a high-pressure portion in the pressure room 43 and pressing force which operates on the piston 24.
