Abstract: Disclosed is an image forming apparatus including a recording head; a cap member capping the nozzle surface of the recording head and including a release port and a suction port; a suction unit in communication with the suction port; a switch unit opening and closing the release port to the air and capable of adjusting the opening amount of the release port to at least a first opening amount and a second opening amount larger than the first opening amount; and a control unit that controls the suction unit and the switch unit so that the release port is opened to the first opening amount to have a predetermined amount of air flow into the cap member after the cap member is suctioned by the suction unit, and the release port is then opened to the second opening amount.

Abstract: An image forming apparatus includes a recording head configured to have a nozzle face on which nozzles that discharge liquid droplets are formed; a cap configured to cap the nozzle face of the recording head; a discharge path configured to be connected to the cap; a suction pump configured to be provided in the discharge path and be made of a tube pump; and an atmosphere opening part configured to open an airtight space, created when the nozzle face is capped by the cap, to the atmosphere. The atmosphere opening part is configured to communicate with the inside of the cap at a position higher than a surface of liquid discharged into the cap, and a check valve configured to prevent a flow of the liquid toward the cap from the suction pump is provided in the discharge path.

Abstract: An anti-corrosive agent for preventing corrosion of a heat exchange mechanism composed of a copper pipe for flowing heat exchange medium therethrough and a radiative member made of metal different from the copper pipe in quality and assembled in contact with the copper pipe for radiating heat transmitted from the copper pipe, the anti-corrosive agent containing phenol-modified epoxy resin paint and aluminum powder as main components in a condition where the aluminum powder is uniformly mixed in the epoxy resin paint.

Abstract: The present invention relates to a method for cleaning heavy hydrocarbon scale from a shell and tube heat exchanger or other such equipment incorporated in a device in a petroleum refining plant or the like that processes petroleum hydrocarbons as a raw material. A mixture of petroleum-derived hydrocarbon A which can dissolve the oil component of the heavy hydrocarbon scale and an oxygen-containing polar organic compound B that promotes dissolution and dispersion is employed as the organic cleaning solvent. As a result, the heavy hydrocarbon scale can be removed with surety within a short period of time at low cost.

Abstract: A method for recovering an uncrosslinked synthetic resin waste including dissolving the uncrosslinked synthetic resin waste in a solvent containing, as an active ingredient, one or more oxyisobutyric acid esters selected from an alkyl .alpha.-alkoxyisobutyrate, an alkyl .beta.-alkoxyisobutyrate and an alkyl .alpha.-hydroxyisobutyrate. This invention provides a method for recovering a plastic waste by using a highly safe solvent which is free from the problems encountered in the conventional methods with the use of aromatic hydrocarbons or halogenated hydrocarbons, and comprises non-halogen solvents, forms no substance causing environmental problems, has a high ability to dissolve plastic wastes, has neither toxicity nor any offensive odor, is not accumulated in nature because of its high biodegradability, and has a relatively high boiling point.

Abstract: A method for assembling a motor vehicle body by fixing relative positional relationship among a plurality of motor vehicle body constituent parts by means of positioning members provided in a welding jig which is disposed on each side of an assembly station and, in this condition, welding together the plurality of motor vehicle body constituent parts at a plurality of tack-welding locations. First welding guns of indirect feeding type are mounted on the welding jig to weld a part of the tack-welding portions. A welding robot having mounted thereon a second welding gun is disposed outside the welding jig. The above-described part of the tack-welding portions are welded by supplying electric power from the second welding gun to the first welding guns by pinching, by the second welding gun, feeder terminals of the first welding guns in a condition in which the above-described part of the tack-welding portions are being pinched by the first welding guns.

Abstract: A liquid crystal display (LCD) circuit comprising a duty changing device for changing the driving duty cycle of an LCD in accordance with a power supply switching command signal, and a bias changing device for changing the display bias voltage produced by a bias producing device to cause the LCD to display information, in accordance with a power supply switching command signal externally supplied to the LCD circuit. Even when electric power to be supplied from plural power supplies to the bias producing device is switched in accordance with the power supply switching command signal, a change in the display contrast of the LCD can be suppressed.

Abstract: An electronic system pocketbook apparatus includes a foldable and portable main body, an expansion card holder mounted on the main body, a necessary number of expansion cards held by the expansion card holder, and a communicating unit. The main body has a functions of right and left portions coupled by a cover, is folded upon carrying of the main body so that the right portion overlaps the left portion, a folded portion being fastened by a cover clip provided to the cover, and has basic functions of controlling arithmetic operations and display data processing by using an internal controller, data inputting means, and displaying data on a display unit. The communicating unit performs data transmission/reception between the held expansion cards and the main body via the expansion card holder.

Abstract: A signal recording and reproduction system is used in recording and reproducing signals on and from a recording medium such as a compact disk, laser disk, video disk or digital audio tape. Index data for the recorded contents such as Table of Contents data (TOC) or the like, are stored in the recording medium. The signal recording and reproduction system confirms the time necessary for playing or reproducing a desired reproduction range of record sections in the recording medium, using a small number of steps of operation.
