摘要:
A developing device, an image forming apparatus and an image forming method are disclosed. The developing device includes a housing that stores toner therein; a toner carrying roller that has a plurality of convex portions and concave portions surrounding the convex portions are formed on the surface of the toner carrying roller; and a conductive regulation blade having a free end comes in contact with the surface of the toner carrying roller. The toner includes a conductive external additive as an external additive. The toner carrying roller carries both contact toner which is in direct contact with the surface of the toner carrying roller and non-contact toner which is not in direct contact with the surface of the toner carrying roller, on the concave portion. The regulation blade is applied with a regulation bias voltage of the same polarity as a normal charge polarity of the toner.

A lancing unit (U1) includes a lancing member (2), an auxiliary part (3) which is separate from the lancing member (2), and a supporter (1) detachably supporting these. Preferably, the lancing unit (U1) further includes a cap (29) which covers a needle (21) of the lancing member (2) and which is detachable from the lancing member (2), and the lancing member (2) is supported by the supporter (1) via the cap (29).
摘要:
A measuring instrument (A) includes a pressurizing mechanism (C) which moves at least one of a measuring article (S) and a connector (4) toward and into pressing contact with the other when the measuring article (S) is placed at a measuring position (P). This prevents improper connection between the connector (4) and the measuring article (S) caused by wear of the connector (4).
摘要:
The present invention provides an analysis tool that can achieve excellent stirring efficiency and can yield highly accurate and reliable analytical values. An analysis tool 1 for analyzing a component in a sample by reacting it with a reagent includes: the reagent, a magnetic material for stirring the sample and the reagent to mix them together; and a reagent arrangement portion 13. In the reagent arrangement portion 13, the reagent and the magnetic material are provided separately (the reagent parts 17 and the magnetic material part 18), and the magnetic material is fixed to the reagent arrangement portion 13 (the magnetic material part 18) with a water-soluble paste. As the water-soluble paste, it is possible to use carboxymethyl cellulose, for example. As the magnetic material, it is possible to use magnetic beads, for example.
摘要:
In an air servo cylinder formed by integrally combining an air cylinder, servo valves, and a controller via a manifold block, there are provided, in the manifold block, air discharge flow paths for releasing, to the outside, compressed air discharged associated with operations of the servo valves. In each of the air discharge flow paths, a silencer for reducing exhaust noise is incorporated so as not to protrude from the manifold block to the outside.

A reconfigurable operation apparatus includes a reconfigurable circuit, a storage unit and a control unit. The reconfigurable circuit has a plurality of small circuits and reconfigures a circuit using the small circuit selected from the plurality of small circuits based on recorded circuit information. The storage unit stores first and second circuit information which corresponds to first and second compression circuits, respectively. The control unit reconfigures the reconfigurable circuit into the first or second compression circuit by recording the first or second circuit information in the reconfigurable circuit in accordance with an input data string.

An analysis apparatus is an apparatus that performs electrophoresis using a microchip provided with a channel. The analysis apparatus includes a cooling unit (an electron cooling element and a driving circuit) that cools the microchip, a voltage application unit (electrodes and a power supply circuit) that applies voltage to a buffer solution filled in the channel of the microchip, an optical analysis unit (a light source, a light receiving element, and an analysis unit) that conducts, through the microchip, optical analysis of a sample introduced in the channel, and a control unit that controls the cooling unit, the voltage application unit, and the optical analysis unit. The control unit causes the cooling unit to start cooling the microchip, and after the microchip has been cooled, causes the voltage application unit and the optical analysis unit to operate.
