A capping device to be used with an ink jet recording apparatus for recording on a recording medium by discharging ink onto the recording medium comprises a capping member for covering a discharge port of an ink jet recording head for discharging ink to effect the recording on the recording medium and a pushing member provided on the capping member at an inner side thereof for pushing with pressure against the discharge port of the ink jet recording head. An ink jet recording apparatus is disclosed using the capping device.
摘要:
A recording apparatus which records on a recording medium. The recording apparatus includes a recording head which prints on a recording medium, a body of revolution which is rotatably mounted, and a platen roller capable of being displaced in the recording head direction and in the body of revolution peripheral direction. The platen roller is positioned against the recording head.

A recovery system comprises a cap means for covering the discharging ports of a recording head to perform recording by discharging ink, and a wiper assembly for wiping the discharging port face of the recording head, the wiper assembly being a large-sized wiping member and a small-sized wiping member, wherein the small-sized wiping member is first in contact with the discharging port face of the recording head. A guide member guides the recording head and the cap at the time of mating and a holder holds the recording head and cap, which holder holds the recording head and said cap in such a manner that they can relatively be displaced in the direction crossing the contacting direction thereof. A cap unit with the cap and wiper assembly can be rotated within a rotational area of the recording head. Wiping by the wiper assembly is performed in such a manner that following the rotation of the recording head, the small-sized wiping member is first in contact therewith and subsequently, the large-sized wiping member is in contact therewith.

A facsimile apparatus comprises a facsimile unit for sending data corresponding to image data that has been received, and a printer unit for performing image recording by discharging ink droplets in accordance with data sent from the facsimile unit. A first CPU for the control of the facsimile unit sends, after one page of image data, data in a predetermined pattern and further a paper exhausting command to the printer. A second CPU of the printer unit performs a paper exhausting operation upon receiving the paper exhausting command, after recording of the predetermined pattern, and upon conveying the recording paper up to a predetermined position, sends a signal for starting detection of the predetermined pattern to the first CPU. The first CPU thereby receives a detection signal from a photo sensor. The second CPU further conveys the recording paper, and at a timing of exhausting out of the apparatus, sends a signal for the detection end of the predetermined pattern to the first CPU. Thereby, it is possible to detect correctly the pattern for detection of the emptiness of ink and the recording paper jam which is recorded at the trailing portion of the recording paper.

A wiping apparatus for a recording head of an ink jet recording apparatus, which has a recording head including an ink ejection portion, includes a wiping member, and a rotation device for rotating the recording head and/or the wiping member so that the wiping member slides on the ink ejection portion. The apparatus prevents the splash of ink caused when the wiping member leaves the ink ejection portion by using one of the following techniques: First, a wiping speed is decreased at the end of wiping; second, an angle between the wiping member and the ink ejection portion is declined as the wiping proceeds; third, the first and second techniques are combined; and fourth, an approach amount of the wiping member to the ink ejection portion is reduced at least just before the wiping member leaves the ink ejection portion. Using one of these technique enables the wiping member to leave softly the ink ejection portion by weakening the restoring force of the wiping member, thereby preventing ink from splashing into the surroundings during the wiping operation.

A data recording/reproduction method and apparatus uses an optical disk equipped with wobbling track guide grooves disposed in a track scanning direction and minutely wobbled. The apparatus uses a circuit for detecting and correcting displacement of an optical spot position from the wobbling track, and a system for allowing data to correspond to front and rear edges of recording pits as a recording system, and includes a circuit for independently handling reproduction pulses obtained from reproduction signals of the recording pits on the front and rear edge sides and for generating reproduction clocks. A circuit resynthesizes the two series of reproduction pulse trains by a specific pattern portion in the data. Another optical disk apparatus divides each track into zones, and switches a rate of revolution each zone to attain a substantially equal linear velocity. A servo signal reproduction clock generation circuit and a data signal recording/reproduction clock generation circuit are disposed separately. The latter changes a frequency division ratio in accordance with the zones so that a clock having a predetermined frequency can be generated even when the rate of revolution changes.

The present invention provides a non-aqueous electrode secondary battery supplied with a non-aqueous electrolyte comprising an overcharge additive. The positive electrode material layer constituting the positive electrode in the non-aqueous electrolyte secondary battery is characterized by having a differential pore volume peak A as well as a peak B located on the smaller pore diameter side than the peak A in a pore diameter range of 0.05 μm to 2 μm in a pore size distribution curve measured by a mercury porosimeter, wherein the pore size distribution curve has a minimum C corresponding to a minimum differential pore volume between the peak A and the peak B, such that a ratio (XC/XL) of the minimum C's differential pore volume XC to a differential pore volume XL, which is the larger between the peak A's differential pore volume XA and the peak B's differential pore volume XB is 0.6 or larger.
摘要:
A grinding abnormality monitoring method and device for grinding a plurality of works of the same type are proposed which can improve the accuracy of judgment whether an abnormality is generated or not by properly setting a threshold value. According to the method or the device, by setting at least one of upper and lower limit values of a trial grinding load detected at the trial grinding of at least one of the works, an occurrence of grinding abnormality is judged when an actual grinding load detected at the actual grinding of work exceeds at least one of the upper and lower limit values thereof which varies depending on the time elapsed from the start of the actual grinding or a position of work relative to a grinding wheel.
