摘要:
A tubular film process wherein molten resin is extruded from an extrusion die into a tubular resin, blown by an internal pressure, cooling air is discharged at least at a point between the vicinity of the extrusion die and the vicinity of a bubble expansion ending point in a direction of the extrusion of the resin and in a direction opposite to the extrusion of the resin to, thereby cool the tubular resin, and the tubular resin is continuously taken up upon being cooled and solidified. The cooling air has higher flow rate in the extrusion direction. The cooling air is discharged not only in the direction of the extrusion of the resin but also in the direction opposite to the extrusion of the resin, whereby hot air stream is prevented from accompanying the flow of the resin, thus enabling to effectively cool the tubular resin.

On-board equipment for a mobile telephone system has a function of reporting the degree of busyness of message channels available in a service area. While the equipment is in a stand-by condition with no communication being held thereon, the degree of busyness is determined on the basis of electric field levels of individual message channels or control information sent from a control station. When the electric field levels are used to determine the degree of busyness, the electric fields of a plurality of message channels assigned to the service area are detected. If any of the message channels has an electric field level higher than a predetermined level, that message channel is determined to be busy. The rate of use of the message channels is calculated by using the number of assigned message channels and the number of occupied message channels. The calculated rate of use is displayed as information which is indicative of the busyness of the message channels. When the busyness is determined on the basis of control information, a lockout signal sent from the control station and indicative of the fact that no idle message channels are available is detected. The number of lockout signals having appeared within a predetermined period of time is determined and displayed as busyness information.

When a power supply is cut off on updating programs, improper data remains since the power source to be supplied to the vehicle-mounted device is unstable. The check for the improper data and restoration processing are required for a reactivation processing implemented by an update processing unit so that the update is completed correctly, therefore, the user is waited. In contrast, the update processing also implemented by the update processing unit for a time period during which the power source becomes unstable is interrupted, and implemented for the time period during which the power source voltage is stable. The power source voltage is considered to be unstable based on a function of the vehicle speed, brake pedal actuation, parking brake actuation, and/or power source activation. In consequence, the update processing is carried on steadily without making the user wait.

In the state where a handle (2) and a lid (12) are attached to a main body (11), left and right bases (22) of the handle (2) are fitted into recesses (1112, 1113) at coupling portions (111, 112). Left and right shaft supports (91) of the lid (12) are fitted into recesses (1111, 1114). Shaft portions (81) of the left and right bases (22) are fitted from above into a through hole (72) and a through hole (73), respectively, and are supported rotatably about a center axis (200) in the through holes (72, 73). Shafts (93 to 95) of the shaft supports (91, 92) are laterally fitted into through holes (71, 74, 75), respectively, and are supported rotatably about the center axis (200) in the through holes (71, 74, 75). The shaft (94) of the shaft support (92) is laterally fitted into a blind hole (82) of the right base (22).

A shredding machine has a rotary cutter and a fixed cutter. The rotary cutter includes a cutter part with a spiral cutting edge and a flute, and a column part for rotatably holding by a holding member for rotation of the rotary cutter. The fixed cutter has a cutting edge contacting with the cutter part of the rotary cutter. In rotating the rotary cutter, longitudinal slips of documents are fed between the cutters so that the documents enter the flute of the rotary cutter to cut the slips into chips by cooperation between the cutting edge of the rotary cutter and the cutting edge of the fixed cutter.

A color electrophotographic image forming apparatus includes: a drum cartridge, detachably mountable to the apparatus main assembly, for holding a drum; developing cartridges, each including a developing roller for developing an electrostatic latent image formed on the drum, demountable from the cartridge; a main assembly guide for guiding the cartridge from the main assembly; a drum cartridge guide for guiding the developing devices independently demountably from the cartridge; and a drum cartridge preventor for preventing movement of the cartridge. When the developing cartridge is demounted while drum cartridge is mounted in the main assembly, the preventor is movable between a first position preventing the cartridge from moving in a demounting direction and a second position permitting such movement. The apparatus includes a grip for facilitating demounting of the drum cartridge by facilitating a change of the preventor's position from the first position to the second position.

A multi-speed internal bicycle hub transmission assembly includes a hub axle, a driver, a hub shell, a power transmission mechanism and a shift control mechanism. The driver and the hub shell are rotatably supported to the hub axle. The power transmission mechanism is disposed between the driver and the hub shell for transmitting rotational power from the driver to the hub shell. The shift control mechanism includes a shift controller and a positioner. The shift controller is movable in rotational directions relative to the hub axle to a plurality of orientations. Each orientation of the shift controller corresponds to selection of a corresponding one of plurality of power transmission paths of the power transmission mechanism. The positioner is non-movable in the rotational direction relative to the hub axle and is biased into contact with the shift controller.

A device capable of producing an annular magnet or arcuate magnet with excellent dimensional accuracy and magnet performance, of which the mass is not greatly scattered. The device for producing the annular magnet, for example, includes a preforming section for obtaining an annular preformed body from a compound of a mixture of an anisotropic magnet powder and a thermosetting resin, a magnetic field orienting and forming section for obtaining an annular intermediate formed body by subjecting the annular preformed body to orienting and pressure-forming, a main forming section for obtaining an annular magnet by further forming the annular intermediate formed body, and a work transferring section for transferring works. The preforming section is provided with mass measuring means for measuring the mass of the annular preformed body, and a first lower punch of the preforming section is so arranged as to vary the volume of an annular cavity by varying the position thereof, which is before the pressure-forming process with a servomotor based on the mass of preformed body, which has been measured with the mass measuring means.
