The quantitative value is corrected at a processing efficiency in various processes until the target nucleic acid in the sample is quantified, and it is thus possible to obtain a highly-precise quantitative value where a correction has been made for a portion of the target nucleic acid that has been lost in various processing stages.

Abstract

A sheet separation device includes a sheet separation unit, a displacement detector, a displacement adjuster, and a controller. The sheet separation unit performs a sheet separating operation and a sheet inserting operation. The displacement detector detects a displacement amount of the two-ply sheet when the two-ply sheet is displaced in a width direction of the two-ply sheet and detects a displacement amount of the inner sheet. The displacement adjuster adjusts the displacement of the two-ply sheet in the width direction before the sheet separating operation, based on the displacement amount of the two-ply sheet in the width direction detected by the displacement detector. The controller causes the displacement adjuster to adjust relative positions of the two-ply sheet and the inner sheet between the sheet separating operation and the sheet inserting operation, based on the displacement amount of the inner sheet in the width direction detected by the displacement detector.

The crimper presses and deforms a bundle of media including the medium to which the liquid is applied by the liquid applier, to bind the bundle of media. The controller causes the liquid application member to move with respect to the medium, based on height information of the medium, so that an amount of the liquid applied to the medium by the liquid application member is equal to a designated amount.

Abstract

A surface emitting laser includes: multiple active layers; a resonator including a tunnel junction between the multiple active layers; multiple reflectors sandwiching the resonator between the multiple reflectors; and an electrode pair connected to a power supply device through which a current is injected into the multiple active layers. The surface emitting laser does not oscillate a laser beam during a current injection period in which the power supply device injects the current into the multiple active layers through the electrode pair; and oscillates the laser beam during a current decrease period after the current injection period. The current injected into the multiple active layers during the current decrease period is lower than the current injected into the multiple active layers during the current injection period.

The operation panel includes second power supply control circuitry that controls power supply in the operation panel, and a second communication interface that communicates a signal with the processing apparatus. In response to receipt of a signal indicating a communication error between the operation panel and the processing apparatus, the first power supply control circuitry starts the timer and notifies the first kernel of the communication error. The first kernel requests the timer to extend a time, based on a time to be taken for processing performed by the processing apparatus. In response to receipt of a signal indicating power-off from the second power supply control circuitry, the first power supply control circuitry powers off the processing apparatus to start rebooting.

Abstract

A head driving device is coupled to a head unit to discharge a liquid from a nozzle. The head driving device includes a voltage application unit and circuitry. The voltage application unit applies a voltage to the head unit including a valve that moves between a nozzle open position to open the nozzle and a nozzle close position to close the nozzle, an actuator that moves the valve, and a temperature detector that detects a temperature of the actuator. The circuitry causes the voltage application unit to: apply a first voltage to the actuator to move the valve to the nozzle close position; apply a second voltage different from the first voltage to the actuator to move the valve to the nozzle open position; and vary the second voltage based on the temperature detected by the temperature detector.

Abstract

An image forming apparatus includes an image bearer, a transfer member, a cleaning member, and a control unit. The transfer member contacts the image bearer to form a transfer nip and transfer a toner image on the image bearer to a recording medium at the transfer nip. The cleaning member cleans a surface of the image bearer. The control unit executes a cleaning operation of moving an extraneous matter adhering to the transfer member to the image bearer to clean the transfer member. The control unit executes the cleaning operation after a toner image pattern that is not transferred to the recording medium passes through the transfer nip and before the recording medium enters the transfer nip.

Abstract

A toner container (32) includes a rotatable container body (33). The container body includes an opening portion (33c) and a plurality of projections (33a). The opening portion is on a first end, which is opposite a second end, of the container body in a rotation axis direction. The plurality of projections are each protrude inward and have a slope inclined with respect to the rotation axis direction. The plurality of projections are disposed such that, out of two adjacent projections in the rotation axis direction, one projection closer to the first end of the container body in the rotation axis direction overlaps the other projection closer to the second end of the container body in the rotation axis direction, in an area of the one projection closer to the second end and an area of the other projection closer to the first end in the rotation axis direction.
