摘要: A random copolyester is described, comprising recurring moieties represented by formula (I), (II), and (III), and having an intrinsic viscosity of not less than 0.5, wherein said recurring moieties of formulae (I) and (II) are existing substantially in equimolar amount and recurring moieties of formulae (I) and (III) are present in a molar ratio of from 95/5 to 5/95 ##STR1## wherein Ar.sub.1 represents a trivalent aromatic group and Ar.sub.2 represents a divalent aromatic group. In formulae (I), (II), and (III), aromatic rings may be substituted with an alkyl group or an alkoxy group having from 1 to 20 carbon atoms, an aryl group or aryloxy group having from 6 to 20 carbon atoms, or a halogen atom. The copolyester obtained is excellent in heat resistance and flame retardance.

摘要: A retractable type wiper apparatus including a first crank connected to an output shaft of a reducer of a wiper motor and a second crank rotatably secured to the first crank by use of a first pivot shaft and so arranged that the second crank is maintained in a bent orientation at a predetermined angle relative to the first crank during the rotation of the first crank in the forward direction. The second crank is extended substantially straight relative to the first crank during the rotation of the first crank in the reverse directions. A stop member is provided on the first crank for defining a first locking recess and a second locking recess. A detent is longitudinally slidably mounted on the second crank. A spring means urges the detent selectively into the first and second locking recesses to thereby lock the second crank in place when the second crank is positioned at the predetermined angled position and at the straight extended position, respectively, relative to the first crank. The link member is rotatably connected to the second crank by a second pivot shaft for transmitting the motion of the second crank to a wiper blade. A cam member is rotatably mounted over the second pivot shaft and adapted to press and lock the detent as it is urged into either the first or second recess.
摘要翻译: 一种可伸缩式刮水器装置,包括连接到刮水器马达的减速器的输出轴的第一曲柄和通过使用第一枢轴可旋转地固定到第一曲柄的第二曲柄,并且布置成使得第二曲柄保持弯曲 在第一曲柄在向前方向旋转期间相对于第一曲柄以预定角度定向。 在第一曲柄在相反方向旋转期间,第二曲柄相对于第一曲柄基本上直线延伸。 止动构件设置在第一曲柄上,用于限定第一锁定凹部和第二锁定凹部。 棘爪可纵向滑动地安装在第二曲柄上。 当第二曲柄分别相对于第一曲柄定位在预定的倾斜位置和直的延伸位置时,弹簧装置选择性地将制动器推入第一和第二锁定凹槽中,从而将第二曲柄锁定在适当的位置。 连杆构件通过第二枢轴可旋转地连接到第二曲柄,用于将第二曲柄的运动传递到刮水片。 凸轮构件可旋转地安装在第二枢转轴上并且适于在制动器被推入第一或第二凹槽中时将制动器按压并锁定。
