摘要： An ink jet head for discharging ink comprises a plurality of elemental substrates having a plurality of discharge energy generating elements arranged in line for discharging ink, a grooved member having a plurality of walls joined with the plurality of elemental substrates arranged to constitute ink paths for each of the discharge energy generating elements, these ink paths being formed by joining the walls of the grooved member under pressure with the plurality of elemental substrates thus arranged, and among the plurality of walls, a plurality of ribs formed on the bottom of each wall arranged on each boundary between elemental substrates, and configured along this boundary line to abut upon each of different elemental substrates, respectively. In this way, any gaps and steps existing between the elemental substrates are sealed by the ribs formed for the walls of the grooved member when this member is joined with the elemental substrates under pressure, thus preventing any ink leakage from such gaps or steps, and also, suppressing the pressure wave cross talk between ink paths in order to perform recording in good condition.
摘要翻译：一种用于排放墨水的喷墨头包括多个元素基片，其具有排列成排列墨水的排列能量产生元件的多个排放能量产生元件，一个带多个壁的多个壁连接的带槽构件，该多个基底布置成构成每个的排出能量产生元件，这些油墨通道是通过在加压下与带槽构件的壁接合而形成的，并且在多个壁之间形成多个肋，每个壁形成在每个壁的底部上，在元件基板之间的每个边界上，并且沿着该边界线分别配置以抵靠每个不同的基底基板。以这种方式，当元件与元件基板在加压下接合时，在元件基板之间存在的任何间隙和台阶都被形成用于凹槽构件的壁的肋密封，从而防止油墨从这种间隙或台阶中渗漏，也抑制油墨路径之间的压力波串扰，以便良好地进行记录。

摘要： A cleaning device for an ink jet recording head, having at least one discharge port for ejecting recording liquid, includes a cap member for facing a region of the recording head having the discharge port therein, a supply path for supplying a fluid medium to the cap member for flow along the discharge port region and a discharge path for discharging the medium from the cap member. The flow of the medium inside the cap member from the supply path to said discharge path is constricted by a protruding portion in the cap member, which protruding portion is disposed in the cap member such that the discharge port is spaced opposite the protruding portion when the discharge port region faces the cap member, and the medium flows along the discharge port region such that a negative pressure is generated for drawing recording liquid from the discharge port into the flow of the medium.

摘要： A recording element unit includes a support member, a recording element provided on the support member and having a wiring layer for supplying electrical signals, and a bump-shaped electrode connected to the wiring layer so as to be raised therefrom. The bump-shaped electrode includes a plurality of raised portions. Such a bump-shaped electrode is also included in a recording element driving unit, an ink jet unit, and an ink jet driving unit. This arrangement solves the problem of the low reliability of the electrical connection between a recording element substrate, on which the electrode is positioned, and a driving element substrate, for driving the recording element. The unit also includes first and second protective layers with the second protective layer having a thickness greater than that of the first. This feature provides structural strength to the support member in order to prevent warping.

摘要： A color copier scans an original carrying a multi-color image in one direction to form toner images of different color components thereof on respective photosensitive drums while moving a transfer sheet in the opposite direction to transfer in registration thereon the several toner images and thereby form a composite color image of the original without reversing the rotational direction of the drums. After the latent image on a given drum is developed with a toner of a respective color, the drum is quenched to remove residual charge by irradiating it with light of a color which is not significantly absorbed by the toner on the drum. The quenching light color differs as between different drums, and for a given drum the quenching light color differs from the color of the light used to form the latent image on that drum.

摘要： An amplitude equalizer is provided for equalizing amplitude distorted signals within a predetermined frequency band. The amplitude equalizer comprises first means for splitting signals into first and second split signals. A first delay device receives one of the two split signals, and a second signal splitter splits the output of the first delay device into third and fourth split signals, the third split signal being applied to a second delay device having a delay equal to the delay of the first delay device. The output of the second delay device is combined with the second output from the first signal splitter in a first signal combiner, the output of which is applied to a circuit for adjusting the polarity and gain of the signal applied thereto. The output of the polarity and gain adjusting circuit is applied to a second signal combiner which combines the adjusted signal with the fourth output from the second signal splitter to thereby provide equalized signals. As organized above, the equalizer can provide for arbitrary selection of the desired frequency regions and maximium equalized amplitude by simply varying either the amplitude or attenuation factor, and by properly choosing the delay time. Further, equalization of secondary and higher order distortion can be achieved by virtue of constant delay over the entire frequency region.

摘要： In successively copying a plurality of continuous pages of a book original by means of a copying apparatus adapted to print images of the pages on opposite surfaces of each copy sheet, a printing operation is controlled in such a manner that a series of processes including, illumination of the pages, charging and exposing of a photosensitive drum, developing, fixing and transfer printing of visible images, and ejection of printed copy sheets is automatically performed, if the book original is opened at desired pages and placed on an original placing glass plate of the copying apparatus in a normal condition in which the top of the book original is remote from the operator. With the operator merely turning the pages, the control method enables the production of a bundle or bundles of duplicate copies of the pages of the same order and arrangement as the book original, regardless of whether the book original is bound on the left side or on the right side and whether the first and last pages to be copied have even numbers or odd numbers. In copying the adjacent two pages, two pages can be copied in separate copying processes or in a single continuous copying process for the two pages.
