An ink-feeding device is provided in which the pressure applied to the ink in the printing head can be adjusted arbitrarily irrespective of the relative positions of the ink container and the printing head. Inside the sub-tank 80, a pressure-adjusting pump 82 is installed for applying a suitable pressure to many nozzles 22Kn of the printing head 22K. This pressure-adjusting pump 82 is placed a little above the bottom face of the sub-tank 80 at a prescribed distance from the bottom face. Thereby the pressure-adjusting pump 82 is immersed in the ink held in the sub-tank 80. A drive unit 83 for driving the pressure-adjusting pump 82 is placed above the sub-tank 80. On the upper wall of the sub-tank 80, an air-vent valve 84 is fixed to bring the inside pressure in the sub-tank 80 to an atmospheric pressure. The inside pressure in the sub-tank 80 is made equal to the atmospheric pressure by opening the air-vent valve 84.

The invention provides a sound recording method, device and system. The sound recording method comprises the steps of acquiring a first voice signal collected by a gun type microphone array and a second voice signal collected by a circular microphone, performing beam forming on the first voice signal and the second voice signal, determining the direction of a second party speaker to be recorded according to beam forming output, performing speaker voice separation according to the directions of a first party speaker and the second party speaker, and obtaining a separated recording voice signal of a first party and a second party, wherein the end of the gun type microphone points to the first party to be recorded; the person number of the first party is one; and the person number of the second party is one or more. The method can improve sound recording quality, and achieves speaker voice separation at the same time, so that role separation during subsequent sound recording and transcription is facilitated, and back listening and looking are facilitated.

The present invention discloses methods of archiving and optimizing lectures, presentations and other captured video for playback, particularly for blind and low vision individuals. A digital imaging device captures a preselected field of view that is subject to periodic change such as a whiteboard in a classroom. A sequence of frames is captured. Frames associated with additions or erasures to the whiteboard are identified. The Cartesian coordinates of the regions of these alterations within the frame are identified. When the presentation is played back, the regions that are altered are enlarged or masked to assist the low vision user. In another embodiment of the invention, the timing of the alterations segments the recorded audio into chapters so that the blind user can skip forward and backward to different sections of the presentation.

We describe a system for electric field assisted magnetic recording where a recordable magnetic medium includes a magnetic recording layer of high coercivity and vertical magnetic anisotropy that is adjacent to an electrostrictive layer which can be placed in a state of stress by a electric field or which is already pre-stressed and which pre-stress can be turned into strain by an electric field. When the magnetic medium is acted on simultaneously by a magnetic writing field and an electric field, the stress in the elctrostrictive layer is transferred to a magnetostrictive layer which is the magnetic recording layer by itself or is coupled to the magnetic recording layer, whereupon the magnetic recording layer is made more isotropic and more easily written upon. Residual stresses in the electrostrictive layer can then be removed by an additional electric field of opposite sign to the stress-producing field.
