摘要:
According to one embodiment, a sheet conveying device includes a paper feeding roller, a separating roller, a double-feed detection section, a double-feed determining section, a torque limiter, a driving section, and a driving force-input control section. The paper feeding roller conveys a sheet. The separating roller separates sheets doubly fed to a nip between the separating roller and the paper feeding roller. The double-feed detection section detects conveyance state of the sheets to the nip and outputs a detection signal. The double-feed determining section determines, on the basis of the detection signal, whether sheets conveyed to the nip are doubly fed. If only one sheet is conveyed to the nip, the torque limiter allows the separating roller to be driven to rotate following the paper feeding roller. The driving section inputs driving force to the separating roller via the torque limiter. If the double-feed determining section determines that the sheets are doubly fed, the driving force-input control section causes the driving section to input the driving force to the torque limiter and, if the double-feed determining section determines that the sheets are not doubly fed, the driving force-input control section stops the input of the driving force to the torque limiter by the driving section.

Semiconductor substrates with high aspect ratio recesses formed therein are described. The high aspect ratio recesses have bottom surface profile characteristics that promote formation of initial growth sites of plated metal as compared to the side surfaces of the recesses. Processes for making and plating the recesses are also disclosed. The metal-plated high aspect ratio recesses can be used as X-ray gratings in Phase Contrast X-ray imaging apparatuses.

A method of manufacturing a liquid ejection head in which a pressure chamber for storing an ejection liquid is connected with an ink supply channel through a restrictor, includes the steps of: forming first spaces for the liquid supply channel and the pressure chamber in a silicon substrate by performing anisotropic etching on a surface of the silicon substrate, the surface of the silicon substrate being parallel to a Si(110) plane, each of the first spaces being defined by two vertical walls and two inclined walls, each of the two vertical walls being parallel to a Si(111) plane that is perpendicular to the surface of the silicon substrate, each of the two inclined walls being parallel to a Si(111) plane that is inclined with respect to the surface of the silicon substrate; then forming an etching protection film on the silicon substrate, the etching protection film protecting the silicon substrate from being etched; then forming an opening corresponding to a second space for the restrictor in the etching protection film; and then performing anisotropic etching on the surface of the silicon substrate through the opening of the etching protection film to form the second space in the silicon substrate, the second space for the restrictor being defined by two inclined walls each of which is parallel to the Si(111) plane that is inclined with respect to the surface of the silicon substrate, the second space connecting the first spaces for the liquid supply channel and the pressure chamber with each other.
摘要:
A first substrate 10 having a channel 12 which passes through the inside thereof and an opening 14a or 14b of the channel which is formed on at least one side thereof, and a second substrate 20 for forming a nozzle hole communicating with the channel are prepared. The second substrate is bonded to the one side of the first substrate where the channel opening 14b is formed so that the opening is blocked by the second substrate. The second substrate is etched with a mixed etching fluid, which contains a high-pressure fluid and an etching solution, fed thereto via the channel of the first substrate, thereby forming the nozzle hole 22 communicating with the channel.
