    摘要: In a process for producing a polycarbonate by subjecting a dihydroxy compound and a diester of carbonic acid to melt polycondensation through transesterification, after a polycarbonate prepolymer is prepared in the first-stage reaction, polycondensation is conducted as the second-stage reaction at a residence time in the range of from 15 to less than 60 min or through the use of at least one paddle-type self-cleaning twin-screw extruder.This process enables a colorless, transparent polycarbonate having a high molecular weight to be produced at a high efficiency on an industrial scale.

    摘要: A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit; a main chassis case; a fluid-containing pack; a container case; and a plurality of holders. The fluid ejection unit ejects a fluid onto an ejection target. The main chassis case houses the fluid ejection unit. The fluid-containing pack contains a fluid for ejection. The container case houses the fluid-containing pack. The plurality of holders is disposed inside the container case. Each of a plurality of holders includes an incline panel that inclines toward the inside base plane, and the fluid-containing pack rests on the incline panel.

    摘要: A head lamp for a vehicle wherein an actuator is made to be able to be moved to a leveling actuation range corresponding to output from a vehicle body sensor and to a beam change position B out of a leveling actuation range when a beam changing switch is set to a drive beam position, and if the actuator is moved to the beam change position B at least a part covering a lower half of a discharge lamp of the hood is moved back to switch it from a passing beam state to a drive beam state. The actuator for leveling actuation indispensable to be provided for the head lamp for a vehicle having the discharge lamp as a light source, makes it possible also to switch between the passing beam state and drive beam state, thereby dissolving problems of large size and high cost of the head lamp.
