20100069713 | ELECTRONIC ENDOSCOPE SYSTEM - An electronic endoscope system includes an electronic endoscope having a CMOS image sensor on the tip of an insertion section, a light source device for illuminating the interior of a patient's body, and a processing device for reading out image signals from the CMOS image sensor. The electronic endoscope system can operate with a standard imaging mode and a special imaging mode. When the time taken to read out the image signals from all the pixels in the standard mode is defined as T, the light source device in the special imaging mode emits illumination light in every first half period T/2 while switching a wavelength of the illumination light between two different wavebands. In every second half period T/2, the processing device reads out the image signals from the half of the pixels. | 03-18-2010 |
20120259226 | ULTRASOUND DIAGNOSTIC APPARATUS - An ultrasound diagnostic apparatus comprises: an ultrasound probe, the ultrasound probe having a transducer array which transmits ultrasonic waves, receives an ultrasonic echo reflected by a subject, and outputs a reception signal according to the received ultrasonic waves, a signal processor which includes a reception amplifier having an amplifier amplifying the reception signal output from the transducer array and processes the reception signal, a selection unit for switching a current value of a bias current supplied to the amplifier, and a selection switch which performs a switching operation to switch the current value by the selection unit; and a diagnostic apparatus body which produces an ultrasound image according to the reception signal processed by the signal processor of the ultrasound probe. | 10-11-2012 |
20130121471 | RADIATION IMAGE DETECTION APPARATUS AND RADIATION IMAGE PHOTOGRAPHING SYSTEM - A radiation image detection apparatus, includes: a control unit configured to drive an imaging unit so that a radiation image data is acquired, an image receiving unit is reset after acquiring the radiation image data, and a dark image data is acquired; in which: the control unit changes at least one of a reset time of the image receiving unit and a reduction ratio of an reduced image data on the basis of the communication speed by such that the transmission of the reduced image data is completed at least prior to reading-out an electrical charge signal from the image receiving unit when acquiring the dark image. | 05-16-2013 |
20130129053 | RADIATION IMAGE DETECTION APPARATUS AND RADIATION IMAGE PHOTOGRAPHING SYSTEM - A radiation image detection apparatus includes a control unit, during a irradiation detection mode, stops supplying of an operating power to a data processing unit until irradiation of radiation is detected by an irradiation detection unit, and when the irradiation of radiation is detected by the irradiation detection unit, the control unit proceeds to a photographing mode and begins supplying the operating power to the data processing unit. | 05-23-2013 |
20140314435 | TRANSFER DEVICE AND IMAGE FORMING APPARATUS INCORPORATING SAME - A transfer device includes a transfer member and a bias applicator. The transfer member contacts a surface, on which a toner image is borne, of an image bearing body, to form a transfer nip. The bias applicator applies a DC voltage and an AC voltage as transfer bias to transfer the toner image on the image bearing body to a recording sheet in the transfer nip. The bias applicator applies a DC voltage having a same polarity as the DC voltage of the transfer bias and an AC voltage having an amplitude smaller than the AC voltage of the transfer bias or applies the DC voltage having the same polarity as the DC voltage of the transfer bias without applying an AC voltage, when an inter-sheet area that exists on the image bearing body passes through the transfer nip during a continuous image formation period. | 10-23-2014 |
20140328603 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image carrier, a transfer member, a power supply, and a control device that controls the power supply to output a DC-AC superimposed bias or a DC bias to transfer a toner image on the image carrier onto a recording medium. The control device controls the power supply to alternately output a first bias being a DC component the same in polarity as the DC bias and a second bias being a DC component opposite in polarity to the DC bias to clean the transfer member when image formation is not taking place. The first bias is output with two target output values including a first value and a second value lower than the first value. The second bias is output with one target output value. An output time of the second bias is longer than an output time of the first bias. | 11-06-2014 |
20140328604 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image carrier that carries a toner image; a transfer member that forms a transfer nip between the transfer member and the image carrier; and a power supply capable of outputting a superimposed transfer bias in which an alternating current component is superimposed onto a direct current component. The toner image on the image carrier is transferred onto a recording medium in the transfer nip by the superimposed transfer bias or a direct current bias consisting of the direct current component output by the power supply. The apparatus also includes a controller that controls the power supply so that an output target value of the direct current component when the direct current component rises up is larger than an output target value of the direct current component when the toner image is transferred onto the recording medium. | 11-06-2014 |
20140334847 | TRANSFER DEVICE AND IMAGE FORMING APPARATUS INCORPORATING SAME - A transfer device includes an image carrier, a transfer roller, and a moving unit. The moving unit moves the transfer roller between a nip formation state in which the transfer roller forms a transfer nipping portion in contact with the image carrier and a separated state in which the transfer roller is separated from the image carrier. In a contact operation of bringing the transfer roller into contact with the image carrier via the recording medium, the moving unit moves the transfer roller toward the image carrier at a moving velocity slower than that in a pressing operation of generating a predetermined nipping pressure by further moving the transfer roller toward the image carrier after the contact operation. The moving unit causes the recording medium to enter the transfer nipping portion in the contact operation. | 11-13-2014 |
