摘要： Disclosed is a method for producing an aromatic polycarbonate, which comprises treating a molten aromatic polycarbonate prepolymer (obtained by reacting an aromatic dihydroxy compound with a diaryl carbonate) with an inert gas under a predetermined pressure to thereby cause the molten prepolymer to absorb the inert gas, and subjecting the resultant molten prepolymer having the inert gas absorbed therein to polymerization, under a pressure lower than the above-mentioned predetermined pressure employed for the inert gas absorption, to thereby polymerize the prepolymer to a predetermined degree of polymerization. By the method of the present invention, a high quality aromatic polycarbonate which is colorless and has excellent mechanical properties can be produced at high polymerization rate even without using a large amount of an inert gas. Further, even if the production of an aromatic polycarbonate is conducted in a continuous manner, the molecular weight of the produced aromatic polycarbonate can be maintained at a desired level, so that the high quality polycarbonate can be stably produced for a prolonged period of time. Therefore, the method of the present invention is commercially very advantageous.

摘要： In a printer, a sheet discharge port for discharging a sheet therefrom is provided on the upper surface of an exterior case, and a recess portion for preventing invasion of a foreign material into the sheet discharge port is formed in the neighborhood of the sheet discharge port. The recess portion passes by the sheet discharge port, and at least one of the ends thereof is opened to the side surface of the exterior case. The side surface of the exterior case to which the open end of the recess portion is adjacent forms a foreign material discharging passage along which a foreign material discharged from the open end of the recess portion falls down without invading the printer.

摘要： An ink switching cam (40) is rotated interlockingly with forward/reverse rotation of a head driving motor at all times to swing a cassette support member (20). Accordingly, ink belts can be switched with a simple construction without using a solenoid or the like. By setting a movable area of the ink switching cam (40) to be within one rotation, the operations of a print head (10) and the ink switching cam (40) which are interlocked with the forward/reverse rotation of the head driving motor can be simply associated with each other.

摘要： A cutter device includes, in addition to one solenoid 17, two pairs of assemblies disposed in parallel with each other in a direction of movement of a cutter 2, the first pair having a rack 5, a pinion 10, and a clutch 49 to control rotation of the pinion, and the second pair having another rack 6, another pinion 11, and another clutch 50 to control rotation of the pinion. In partial-cutting operation, the cutter 2 is moved by engaging the rack 5 in the first pair with the pinion 10 in the first pair rotated through power from the clutch 49 in the first pair. In full-cutting operation, the cutter 2 is moved by engaging the pinions 10,11 in the first and second pairs concurrently rotated through power from the clutches 49,50 in the first and second pairs with the racks 5,6 in the first and second pairs. The pinion 10 in the first pair causes the full-cutting first half movement of the cutter, and the pinion 11 in the second pair causes the full-cutting latter half movement thereof.

摘要： In a dot impact printer, printing heads impact on an inked ribbon so as to form a pattern of dots on a paper sheet. The more often printing is carried out, the looser the central portion of the inked ribbon becomes. A sensor disposed perpendicularly against a surface of the inked ribbon detects such a condition of the inked ribbon, emitting a signal. Receiving the signal, a control means finds the inked ribbon unusable, interrupting the printing operation, and knowing a timing to replace the inked ribbon. The control means operates an alarm to urge replacement of the inked ribbon. Therefore, the dot impact printer is prevented from performing the printing operation under unfavorable conditions.
摘要翻译：在点冲击打印机中，打印头冲击着墨带，以便在纸张上形成点图案。打印次数越多，着墨色带的中心部分变松。垂直于着墨色带的表面设置的传感器检测着色带的这种状态，发出信号。接收信号时，控制装置发现着墨色带不能使用，中断打印操作，并且知道更换着色色带的时间。控制装置进行警报以促使更换墨带。因此，在不利的条件下，防止点冲击打印机进行打印操作。

摘要： A push-pull printer includes at least one tractor unit thus is formed to have both a pull function and a push function. Fork-like mounting portions are respectively formed at lower portions of a pair of frames provided at both ends of the tractor unit. A pair of tractor guides are located at each of push and pull feed positions of the printer body. Each guide detachably holds a corresponding fork-like mounting portion. When the tractor is to be used in the push type paper feed mode, the fork-like mounting portions are attached to the tractor guides located at the push feed position. However, for use in the pull type paper feed mode, the fork-like mounting portions are attached to the tractor guides located at the pull feed position. Two such tractors, one providing the pull function and the other the push function, can be used cooperatively.
