Abstract: A digital cinema management device includes a control unit that supplies data of contents stored in a storage device to a playback device, in which the control unit refers to the contents stored in the storage device, contents stored in a content storage unit of the playback device, and an exhibition schedule, selects contents which are scheduled to be exhibited by the playback device, and which are not stored in the content storage unit, from the storage device, and supplies data of the selected contents to the playback device.

Abstract: A manufacturing apparatus of a fiber-reinforced resin strand including spreaders that spread a reinforcing fiber bundle and are provided inside a crosshead to which a molten resin material is supplied continuously from an extruding machine, twisting rollers provided at a downstream position from an exit nozzle of the crosshead and that pultrude a fiber-reinforced resin strand formed of a resin-impregnated fiber bundle from the exit nozzle while imparting twists thereto, and twist retaining rollers provided at a downstream position from the twisting rollers and that retain twists of the fiber-reinforced resin strand. The twisting rollers and the twist retaining rollers are made of metal with asperities being formed on the surface thereof. The manufacturing apparatus can achieve excellent durability and is capable of manufacturing a fiber-reinforced resin strand at a high production rate without causing slipping.

Abstract: A heating and extruding method for a bulk preform of a fiber reinforced composite material, including a stabbing machine for forming an unpenetrated hole in the bulk preform, a heating machine connected to the stabbing machine for heating the bulk preform by a nitrogen gas, and an extruding machine connected to the heating machine for heating and compressing the bulk preform heated by the heating machine to discharge a predetermined amount of the bulk preform, wherein at least the heating machine to the extruding machine has a sealing structure sealing a nitrogen gas therein. An extruding lip of the extruding machine has a thickness restriction plate and a width restriction plate for respectively adjusting an extrusion thickness and an extrusion width of the melted composite material. Accordingly, oxidation and degradation of resin composing the fiber reinforced composite material can be prevented.

Abstract: The present invention relates to a method for molding an agglomerated preform of a fiber-reinforced composite material comprising a resin material as a matrix and reinforcing fibers dispersed therein, into a desired shape. In the molding method, the preform is heated from the interior thereof, whereby the temperature of the entire preform can be raised efficiently and uniformly. If an optional number of holes are formed in the agglomerated preform, rod-like heaters for heating or gas nozzles for the release of heated gas can be inserted into the preform easily through such holes, whereby uniform heating can be effected. Further, by incorporating an appropriate amount of a dielectric loss improver into the preform and thereafter subjecting the preform to high-frequency heating or microwave heating, the preform can be heated efficiently and uniformly in a short time.

Abstract: The present invention provides an electrostatographic apparatus having a control circuit (35) which controls an optical unit (5) to scan a photoconductor (1) during a predetermined time period with laser beam lit irrespective of recording signals after stoppage of power supply from a power source (34) to a charger (2) and a developer (7), thereby lowering potential on a surface of the photoconductor (1) after the stoppage of power supply.

Abstract: This invention relates to a joint for risers, and particularly to a telescopic joint suitable for expandably connecting composite-pipe type riser pipes provided internally with tubing pipes. Its structural features reside in that connectors adapted to connect risers in up-and-down relationship are slidably engaged with each other and air cylinders capable of cancelling volume changes of the engaged portions, which volume changes occur due to expansion and contraction movements of the connectors, are communicated to the spacing of the engaged portions, and hydraulic cylinders adapted to cancel volume changes of the engaged portions of an internally-threaded nose portion and an externally-threaded nose portion, which engaged portions serve to communicate the upper and lower tubing pipes to each other, is communicated with the spacing of the engaged portions of the nose portions.

Abstract: An apparatus wherein liquid may be continuously fed at a constant small rate includes a liquid reservoir displaceable up and down and provided at a lower portion thereof with a liquid delivery orifice block, a small liquid dropping tank displaceably supported for up and down movement and provided with a liquid dropping chute and an intake nozzle communicating with the orifice block and disposed at a location lower than the location where the liquid dropping chute is attached to the small liquid dropping tank, a photoelectric droplet counting mechanism provided facing a dropping portion of the dropping chute, and a reservoir raising/lowering mechanism and a tank raising/lowering mechanism adapted respectively to either raise or lower the liquid reservoir and dropping tank in accordance with signals from the counting mechanism.

Abstract: A continuous mixing machine for mixing a material fed at one end and discharging the mixed material through a discharge orifice at another end in a continuous sequence which includes a plurality of rotors each provided with mixing blade members, a mixing chamber encircling the plurality of rotors and a throttle member defining a part of the mixing chamber at a position facing the blade members and adapted to be moved toward and away from the rotors so as to vary the space within the mixing chamber. In a modified machine, the mixing chamber is provided with a vent hole at a position intermediate the throttle member and discharge orifice.
