Abstract: In a liquid ejecting apparatus in which ink is supplied from an ink tank to a print cartridge detachably mounted on a carriage through a tube, connection between an ink needle at a tube side and an interconnecting member at a cartridge side can sealingly be effected positively, and ink supplying and connecting means can be made compact. A closing film having a small hole and a central slit is provided at a tip end of an interconnecting member made of soft material and fitted into an ink flow-in projection portion of the print cartridge into which an ink needle is inserted. Further, a notched needle tip end avoiding configuration is provided at a lower part of a tip end of the projection portion so that abutment between the projection portion and the ink needle can be avoided when the print cartridge is mounted and dismounted, thereby reducing a shifting amount of a needle holding member.

Abstract: An optical pickup applies five different light beams at the same time to every second five tracks on a signal plane of a CD-ROM. A record data read system reads record data independently for each light beam system in accordance with outputs of respective light beams reflected from the signal plane, and stores the read record data in the record order. Under the control of a system controller, the optical pickup and record data read system read the record data of the CD-ROM by alternately performing an operation of continuously reading the record data with the five light beam systems during approximately two rotations of the CD-ROM and a track jump operation by seven tracks in a forward direction after the continuous reading operation with a combination of the five light beam systems shows no omission of the record data of the CD-ROM.

Abstract: In a CD-ROM reader system wherein five adjacent tracks of a CD-ROM are separately illuminated by five light beams of an optical pickup, a recorded data readout system simultaneously reads the recorded data of the separate tracks by detecting the received light outputs of the returned beams, and outputs the data in the sequence in which it was recorded. For example, if one light beam becomes unreadable by the recorded data readout system, the system will read the recorded data using the remaining four light beams. This readout is performed in recurring operations in which data is read for approximately one revolution of the CD-ROM; then, after there are no longer any gaps in the combined data, the pickup is track-jumped forward by approximately two tracks. At this point the recorded data is again read for one revolution, and the process repeats.

Abstract: An ink-jet printing apparatus can maintain a liquid level height in an ink storing portion in an air buffering vessel at a predetermined height and can simplify an associated mechanism for connection between a scanning carriage and a stationary ink tank while a low cost single tube is employed. An air buffering vessel of the ink-jet printing apparatus has one ink supply opening from the ink storage tank and at least two suction and discharge openings located at mutually different height in a vertical direction. Upper opening of the at least two suction and discharge openings serves for air suction and discharge. Lower opening serves for ink supply and discharge, and is communicated with a connection opening of the printing head.

Abstract: A flaw detecting method and apparatus for continuously testing a strip that is continuously carried through a liquid includes features for reducing air bubble generation in a liquid. The apparatus includes a liquid, carrying rolls for passage of the strip through the liquid, and ultrasonic testing probes arranged in the liquid for testing the strip. A carrying roll in contact with the liquid is fully immersed. Air bubble generation is inhibited to improve the testing reliability by at least one of (a) shielding the liquid dropping from the portion of the strip leaving the liquid, (b) reducing the dropping force of the liquid onto the liquid surface by inclining the strip, (c) installing the fully immersed carrying roll at a depth of at least 5 mm in the liquid, and (d) using a carrying speed of less than about 200 m/min. Upon manufacturing steel strips, testing is carried out in the stage of hot-rolled steel sheet, or, preferably, in pickling equipment.

Abstract: The invention relates to a procedure for chemically determining the base sequence of DNA and, in particular, its step of cleaving the labeled DNA having undergone a base-selective chemical modification at the position of the modified base. More particularly, it relates to a method for cleaving DNA which comprises modifying DNA base-selectively with chemical reagents, bringing the resulting reaction mixture into contact with an adsorbent to adsorb the chemically modified DNA on the adsorbent, washing the adsorbent with a washing fluid to remove any chemical modification reagents from the adsorbent, bringing the adsorbent into contact with an eluent to elute the chemically modified DNA adsorbed thereon, concentrating the resulting eluate and then heating it together with a cleavage reagent.

Abstract: A windshield defroster includes a defroster outlet positioned within the dashboard of a vehicle, in which a cover plate is attached within the defroster outlet. The cover plate includes an opening and a plurality of bars which separate the opening into various sections, so that the bars within the cover plate prevent objects from dropping into the defroster outlet. The windshield defroster includes a duct attached to the bottom surface of the dashboard, and a heater is positioned within the duct, so that warm air can be distributed to the defroster outlet through the opening in the cover plate. The cover plate is swingably connected to the duct by a hinge, and the hinge is integrally formed with the duct and the cover plate. The cover plate has a lower surface in the vicinity of the hinge, and the duct has a horizontal first projection in the vicinity of the hinge.
