An ink-jet printing apparatus according to the present invention has a main tank storing ink, a sub-tank releasably connectable with the main tank through an ink supply passage and a printing head for ejecting ink supplied from the sub-tank, for performing printing by ejecting ink from the printing head to a printing medium. The apparatus includes an ink supply controller for supplying ink from the main tank to the sub-tank through the ink supply passage during a period after completion of printing at a preceding time and before starting printing at a next time, and an ink draining controller for performing ink draining of at least a part of ink remaining in the sub-tank during the period after completion of printing at the preceding time and before starting printing at the next time and in advance of ink supply by the ink supply controller.

A lubricating structure in a fixed displacement piston type compressor has a housing, a rotary shaft, a cam, a piston, a rotary valve and a rotary body. The housing defines a cam chamber, cylinder bores and a suction pressure region. The rotary shaft is rotatably supported by the housing. The cam is located in the cam chamber and is connected to the rotary shaft. The piston is located in each of the cylinder bores and engages the cam to reciprocate with rotation of the rotary shaft through the cam. The rotary valve connected to the rotary shaft includes an introducing passage and a supply passage that interconnects the introducing passage and the suction pressure region. The introducing passage introduces fluid into the cylinder bores through the supply passage. The rotary body connected to the rotary shaft includes a communication passage that interconnects the cam chamber and the suction pressure region.

A multilayer inductor is provided with a coil part including a coiled conductor and lead conductors, an outer sheath part covering the coil part and having an electrical isolation, and external electrodes electrically connected to the respective lead conductors. The lead conductors are located at both ends of the coiled conductor and have a width identical with that of the coiled conductor. The outer sheath part has two first side faces parallel to the axial direction of the coiled conductor and not adjacent to each other, and a second side face intersecting with the axial direction of the coiled conductor. Each external electrode has a first electrode portion formed throughout a direction perpendicular to the axial direction of the coiled conductor on the first side face. Each external electrode is not substantially formed on the second side face.

摘要:
The present invention provides an electromagnetic relay that has a long service life, even when being used for interrupting high voltage, and that can be miniaturized. In this electromagnetic relay, the circuit interruption is cut-off by two or more keying circuits, which are operated by a single coil and connected in series. Thus, an amount of generated arc per keying circuit is suppressed. Consequently, the service life of the electromagnetic relay is lengthened. Moreover, the space between the contracts thereof is reduced, so that the electromagnetic relay is miniaturized. Additionally, a magnetic field for extinguishing arc is formed by a back or counter electromotive force generated when the circuit is cut-off. Thus, the generated arc is extinguished.

A tape cassette having a case body including an upper case and a lower case, a recessed portion formed on the side of a lower surface of the case body, and a slider so provided in the case body as to be slidable for opening and closing the recessed portion, is disclosed. The tape cassette further has a lock member positioned at an opening of the lower case to lock the slider in respective positions where the recessed portion is closed and opened, and a biasing member, supported at its two side ends with the opening being interposed therebetween by an inner surface of the lower case, for biasing the slider to a lock position.
摘要:
A cartridge including a housing which holds a tape medium or disk medium and which is composed of upper and lower casings. The two casings are joined with screws in bosses formed at their four corners. The cartridge is characterized in that the bosses in at least one of the upper and lower casings have ends with partially different heights each so that, when the upper and lower casings are joined, their bosses come in contact with one another before the sidewalls of the in casings are mated.
