  • Patent number: 9720009
    Abstract: A sample processing apparatus comprises a transporting section configured to transport a sample rack that is capable of holding a sample container at a plurality of holding positions, a detecting section that is configured to detect presence or absence of a rack distinction member at a holding position of the sample rack, an aspirating section that is configured to aspirate a sample in the sample container, and a control section that is configured to control an aspirating operation of the aspirating section. The control section changes an aspirating operation with respect to the sample container held in the sample rack based on the presence/absence of the rack distinction member at the holding position of the sample rack.

  • Patent number: 8704706
    Abstract: According to one embodiment, a radar return signal processing apparatus includes a detector, an estimation unit and an extraction unit. The detector detects an average Doppler frequency, a spectrum width, and a received power of each of echoes, from a radar return signal obtained repeatedly at regular intervals. The estimation unit estimates an optimum mixed density function by learning modeling a shaped of the frequency spectrum by calculating repeatedly a sum of density functions of each of the echoes. The extraction unit extracts information on any one of the echoes included in the radar return signal, from a parameter of the estimated mixed density function.

  • Publication number: 20140049849
    Abstract: Provided is a lens unit comprising an actuator that is self-supporting when at a stopped position. The lens unit comprises a holding frame that holds a lens; a movement actuator that moves the holding frame, which is connected to a moving member that moves linearly relative to a stator, when drive force is generated, and does not prevent the moving member from moving relative to the stator when the moving member is stopped; and a braking actuator that stops the moving member from moving relative to the stator, using frictional force, when the movement actuator is not generating the drive force, and decreases the frictional force when the movement actuator generates the drive force.

  • Patent number: 7938999
    Abstract: An object of the present invention is to provide: a process for conveniently producing a fiber with high strength, regardless of molecular weight polymer composition, or the like of PHAs, which vary depending on origins such as a wild-type PHAs-producing microorganism product, a genetically modified strain product, and a chemical product; and the fiber with high strength produced through the process. The present invention provides: a process for producing a fiber, comprising: melt-extruding polyhydroxyalkanoic acid to form a melt-extruded fiber; rapidly quenching the melt-extruded fiber to the glass transition temperature of polyhydroxyalkanoic acid +15° C. or less, and solidifying the fiber to form an amorphous fiber; forming a crystalline fiber by leaving the amorphous fiber to stand at the glass transition temperature +15° C. or less; drawing the crystalline fiber; and further subjecting the crystalline fiber to stretch heat treatment.

  • Patent number: 7486407
    Abstract: The main sensor 15 measures the distance Lm to the surface of the pad 2a, and the sub-sensor 16 measures the distance Ls to the surface of the reference block 12. What is actually taken as the measured value is the value of (Lm+Ls). The reference block 12 is used in order to give a reference position for measuring the surface position of the pad 2a. Accordingly, correct measurements can be performed even if the position of the movable element 9 should fluctuate, for example, as a result of deformation of the guiding and holding plate 7 or guide 8. When the motor 11 is caused to rotate, the ball screw 10 rotates, so that the movable element 9 moves leftward and rightward, and the distance to the pad 2a is measured. From the measured data of this distance, the circular-conical vertical angle, groove depth, thickness, and the like of the pad 2a are determined.
