摘要:
An ink jet head includes an electroviscous fluid chamber provided at a part of a sidewall of an ink chamber, and having electroviscous fluid sealed therein, an elastic film provided between the ink chamber and the electroviscous fluid chamber for transmitting pressure between the ink chamber and the electroviscous fluid chamber, a pair of electrodes provided at a part of a sidewall of the electroviscous fluid chamber corresponding to the ink chamber for applying an electric field to the electroviscous fluid, a pressure generation device for discharging ink from the ink chamber, and a control device for controlling ink discharge by applying a voltage to the pair of electrodes to alter the viscosity of the electroviscous fluid in response to record information.
摘要:
An ink jet recording head includes a plurality of plate-like individual heads. Each individual head includes an individual head member having a main surface, a backside surface, a first side surface, and a plurality of second side surfaces. The first side surface includes a plurality of ink jet outlets aligned in a direction parallel to the main surface. Each individual head member includes a plurality of ink paths to supply ink to the plurality of ink jet outlets respectively. Each individual head includes a plurality of drive elements provided on the main surface corresponding to the plurality of ink paths respectively to generate pressure at the plurality of ink paths, and a plurality of electrodes provided corresponding to the plurality of drive elements to apply voltage individually to the plurality of drive elements. The plurality of electrodes have one ends connected to the plurality of drive elements, and the other ends arranged extending up to the neighborhood of any of the plurality of second side surfaces. The plurality of individual heads are stacked in a step-graded manner so that the other ends of the plurality of electrodes are exposed at the neighborhood of the second side surface.
摘要:
A robbery-proof mechanism for a vehicle mounted electronic apparatus wherein a cover for covering the electronic apparatus is accommodated in the upper space of the electronic apparatus and can be driven by a small scale drive mechanism without moving the electronic apparatus. The robbery-proof mechanism includes: a frame mounted on the front of the vehicle mounted electronic apparatus, being rotative between a horizontal position and a vertical position; a cover capable of being inserted into a groove formed in the frame; a drive mechanism for driving the cover in the horizontal direction between a position in the groove of the frame and a position retracted from the frame; and a drive mechanism for driving an operation panel in the horizontal direction, wherein the frame is rotated to the horizontal position, the cover is then moved into the groove of the frame and the operation panel is moved backward, and the frame together with the cover is rotated to the vertical position to cover the operation panel with the cover.
