摘要:
The object of the present invention is to ensure a correct exposure even when a single exposure apparatus is used to expose a predetermined pattern, and an exposure apparatus therefor. According to the present invention, a charged particle beam exposure method, wherein a charged particle beam having a predetermined shape is irradiated to a sample to have the surface of the sample be exposed, comprises the steps of: storing a record of a first quantity of reflected electrons or a first sample current, which is detected in accordance with the charged particle beam irradiatd to the sample when a first exposure pattern is formed in a first area of the sample; and comparing a second quantity of reflected electrons or a second sample current, which is detected in accordance with the charged particle beam irradiated to the sample when the first exposure pattern is formed in a second area of the sample, with the first quantity of the reflected electrons or the first sample current which is stored when the first area is exposed, and generating a matched or unmatched signal therefor.

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 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.

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 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 nonradiative dielectric waveguide which includes a first housing and a second housing. The first housing and the second housing respectively include first and second dielectric units and conductor electrodes. The first and second dielectric units are respectively integrally formed with first and second planar portions, and first and second dielectric strip line portions extending outwardly from said first and second planar portions and by a predetermined height, with abutting faces generally parallel with the conductor electrodes and being provided at top portions of said dielectric strip line portions. The conductor electrodes are respectively formed in close contact with faces of the first and second dielectric units remote from the abutting faces. The first and second housings are overlapped so as to make the abutting faces confront each other. The first and second dielectric strip lines portions cooperate to propagate electromagnetic waves. The disclosure is also directed to a manufacturing method of the above nonradiative dielectric waveguide.
