摘要:
Provided is a fiber grating laser for optical communication which can be used as a light source regardless of the occurrence of mode hopping. The laser module comprises a semiconductor optical amplifier device, an optical waveguide such as an optical fiber, and a diffraction grating such as a fiber grating. The semiconductor optical amplifier device has first and second end surfaces. The optical waveguide is optically coupled to the semiconductor optical amplifier device. The diffraction grating is optically coupled to the optical waveguide. The semiconductor optical amplifier device and the diffraction grating constitute an external cavity. An optical cavity length of the external cavity is in a range of 13 millimeters or more but 27 millimeters or less.

The present invention provides an ink jet printing apparatus of a low-cost and simple construction which can detect with high reliability a gap between a print medium and a print head mounted on a carriage. The ink jet printing apparatus, which reciprocally moves in a predetermined scan direction the carriage holding the print head for ejecting ink onto the print medium, includes a gap changing mechanism for changing the gap between the print head held in the carriage and the print medium and a control unit for controlling a driving of the gap changing mechanism and a reciprocal movement of the carriage, wherein the control unit drives the gap changing mechanism and reciprocally moves the carriage to check the operation state of the gap changing mechanism.

A recording apparatus effects recording on a recording material by a recorder. The apparatus includes a tray, mountable to the recording apparatus, for stacking a recording material, a portion to be detected, provided on the tray to permit detection of a position of the tray, and a tray position detecting portion for detecting the portion to be detected. A position of the recording material stacked on the tray is detected by detecting the position of the portion to be detected.
摘要:
An ink jet recording apparatus and method subjects recording data to conversion, for example, thinning, when the recording data is not text data and a double-sided recording mode is selected. By effecting recording based on this recording data, recording quality is prevented from being reduced due to ink spread and thinning.

In a bonding tool which bonds a component to a substrate by urging and vibration, a through hole is formed in the horn. An adhesion section is fit into a lower section of the hole and an engaging section is fit into an upper section of the hole, so that a sealed inner space is formed inside the hole by tightening an outer screw. An adhesion hole open to a bonding section communicates with a sucking hole of the horn via the inner space, so that a simply structured vacuum-adhesion-system can be formed. This mechanics does not loose replaceablility of the adhesion section detachable to the horn. As a result, the adhesion section can be replaceable as an independent part (urging terminal), and a bonding apparatus as well as a bonding tool having the simply structured vacuum-adhesion-system can be provided.

In a recording apparatus using a plurality of kinds of head cartridges each comprising an ink jet recording head and an ink tank formed as a unit, the present invention prevents, when a wrong head cartridge has been mounted during cartridge exchange, data regarding the remain of ink in a thitherto used cartridge of other kind from being lost, and enables the remain of ink in that cartridge to be confirmed. A user is pressed for the exchange of the head cartridge now mounted to thereby effect the exchange actually, and is called on to confirm whether the newly mounted head cartridge is a right one, and the initialization of the data regarding the remain of ink is effected when the user has done the inputting of the confirmation.
摘要:
An ink jet recording apparatus is provided with at least one first electrode at least in either a recording head or ink retaining member, dielectric adjacent to the first electrode or laying between the first electrodes, a second electrode electrically connected to the first electrode through the dielectric and ink, power supply to apply and release voltage to and from the first electrode, potential difference detector for detecting the potential of the second electrode, and equivalent circuit to determine the ink remains at least in either one of the recording head and ink retaining member in accordance with the potential of the second electrode detected by potential difference detector. In this way, it is possible to provide an ink jet recording apparatus having equivalent circuit for detecting ink shortage, and expect a highly precise detection thereof, and also, to provide information processing systems having such recording apparatus for its output device.
