Publication number: 20080081755Abstract: A centrifugal separating-distributing apparatus includes a body being provided with an intake path, a stacking path, and a distributing path. A fluid sample is taken into the intake path, and the sample flows out from an outlet of the path when a first centrifugal force is exerted at a first rotation angle position. Under the first centrifugal force, the flown out sample flows in an inlet of the stacking path and is separated into plural components and the components are stacked in the stacking path. When a second centrifugal force is exerted at a second rotation angle position, a component closest to the inlet of the stacking path flows into an inlet of the distributing path between the outlet of the intake path and the inlet of the stacking path, and is moved away from the inlet to be separated from the remainder of the components in the stacking path.Type: ApplicationFiled: March 15, 2007Publication date: April 3, 2008Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Takeshi Kinpara, Hajime Sudo, Kenji Ooki, Tomokazu Domon

Publication number: 20040155113Abstract: An invisible symbol reading apparatus includes a heating unit for heating an invisible symbol formed on a sample and containing a material which emits infrared light when heated, a detecting unit for detecting infrared light emitted from the invisible symbol, and an arithmetic operation unit for binarizing a detection signal from the detecting unit. The arithmetic operation unit calculates a differential coefficient of the detection signal, that corresponds to a position on the sample. On the basis of upper and lower threshold values set for the differential coefficient, the arithmetic operation unit determines a maximum value of the differential coefficient in a region exceeding the upper threshold value and a minimum value of the differential coefficient in a region smaller than the lower threshold value. The arithmetic operation unit binarizes the detection signal by using the maximum or minimum value as a loading or trailing edge of a binary function.Type: ApplicationFiled: July 29, 2003Publication date: August 12, 2004Applicant: Kabushiki Kaisha ToshibaInventors: Taeko I.

Patent number: RE34039Abstract: A torque sensor of noncontact type, by which can be stably measured the torque of a shaft with a sufficient S/N ratio under the influence of external magnetic noise, such as an induction magnetic flux which is produced in an induction motor, and which can be readily disposed in a comparatively small space. When provided on an induction motor, the torque sensor is mounted on the induction motor in noncontacting relationship. The torque sensor detects the torque of the shaft and includes a pair of magnetic material members provided on respective circumferential portions of the peripheral surface of a shaft. A pair of magnetic detectors are disposed at opposite locations at which external magnetic fields having opposite phase exist. The detectors detect the variation of the magnetic characteristics of the magnetic materials, and a signal processing circuit produces a mean value of output signals obtained from the magnetic detectors.Type: GrantFiled: January 27, 1989Date of Patent: August 25, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Tadahiko Kobayashi, Masashi Sahashi, Koichiro Inomata, Tomokazu Domon
