By providing dummy pixels separately from effective pixels, the total number of pixel rows is equalized with the number of horizontal sync signals included in one frame interval (which is called an "HD number"). A period during which a reset signal for an electronic shuttering operation is being supplied to an arbitrary pixel row overlaps with a period during which another pixel row is selected to perform a readout operation thereon. Thus, it is possible to suppress a variation in reset potentia...

A twin wire former wherein the forming turbulence of a first forming section is quieted by a main forming roller. Behind the main forming roller, as viewed with respect to a predetermined direction of travel of the forming wires, there is accomplished a further forming of the paper web or sheet from the fiber stock suspension in a second forming section. Due to this arrangement there is possible optimum formation of the paper web or sheet with the use of very little dilution water for the fiber ...

A double screen former for the manufacture of a paper web has two continuous screens forming together a double screen zone. The one screen runs in the double screen zone across rigid laths that are arranged on the dewatering box at a mutual spacing. Additionally, the other screen runs in the double screen zone across several laths which are supported by means of flexible elements and can be forced on the screen at a selective force. The space between the flexibly supported laths is at least appr...

A low power imaging array has a plurality of pixels wherein each pixel converts an intensity of incident light into electrical energy. An operational transconductance amplifier is utilized in conjunction with the imaging array to process the image signals from the low power imaging array. The operational transconductance amplifier includes a current mirror stage with a current mirror gain factor. The current mirror gain factor is selected based on a pixel noise level introduced by the low power ...

An amount of charges consonant with the intensity of the light entering photodiodes is generated, and the level of the charges is determined by a charge level determination circuit. Based on this determined charge level, a capacitance setting circuit sets a capacitance of an integrating capacitor unit in an integrating circuit. Thereafter, in the integrating circuit, the charges generated by the photodiodes are integrated in the integrating capacitor unit, and a voltage having a value consonant ...

An active pixel sensor cell array in which a partial transimpedance amplifier amplifies the output of each cell. The pixel sensor cell array comprises a plurality of pixel sensor cells and a second part of the amplifier. Each pixel sensor cell comprises a photo-sensitive element, a capacitor and a first part of an amplifier. The capacitor is coupled between a terminal of the photo-sensitive element and an output line of the cell. The capacitor is operable to provide a capacitive feedback in the ...

A twin-wire former for a paper machine which can produce paper of good formation over a wide range of basis weight and at a speed of wide variation essentially consisting of a top wire and a bottom wire. The bottom wire with a wet material thereon substantially horizontally travels. The top wire approaches the material from above and travels downward together with the bottom wire on the circumference of a supporting member provided in the loop of the bottom wire while pressing the material betwe...

Each pixel of a solid state imaging element includes a photodiode, a field effect transistor (FET) having a gate connected to an output of the photodiode, a first feedback circuit connecting the gate and drain of the FET with a first switch inserted in series in a middle thereof, a second feedback circuit connecting the gate and drain of the FET with a second switch and a first capacitor in series in a middle thereof, and a second capacitor connected between a middle of the first capacitor and t...

An imaging apparatus includes an imaging unit configured to convert an object image formed by an imaging optical system into an electrical signal, a power supply unit capable of being supplied with power from first and second power supply systems, and a control unit configured to cause the imaging unit to operate in different control modes according to whether power is supplied from the first power supply system or the second power supply system.

The product 3-amino-2-(4-methoxyphenoxy)pyridine and its pharmaceutically suitable salts, in particular the hydrochloride, are novel products which are prepared by catalytic hydrogenation of 2-(4-methoxyphenoxy)-3-nitropyridine, optionally in the presence of the acid corresponding to the salt. Its pharmaceutical compositions containing sufficient amounts of suitable auxiliaries for its topical administration prove particularly useful in therapy for the treatment of inflammatory skin diseases. Th...
