Abstract: A ratchet wrench (20) includes a handle-carried drive ring (38), and a driven core (34) which can be simply and readily removed, intact, for cleaning, repair and replacement without the use of tools. Additionally, the wrench (20) includes a low-friction ratchet drive-reversing mechanism for simple one-finger operation. 
     The disassembly-facilitating structure includes a resilient ring-like band (190) seated in a channel (192) defined by radially communicating annular grooves (180, 184) in the drive ring (38) and in the wrench core (34). A band displacing element (222) serves to shift the band (190) to effect a bridging of the band (190) across the grooves (180, 184) to effect a mechanical intercoupling between the core (34) and the drive ring (38) For disassembly, the band (190) is repositioned to assume a configuration occupying a single one only of the communicating grooves (180, 184) thereby uncoupling the core (34) and the drive ring (38), to permit withdrawal of the core (34) as an intact unit. 
     The drive direction of the wrench (20) is controlled by an arcuate wire spring (104) which intercouples a finger-­manipulable pivotal drive-reversing control plate (60) of the tool with a shiftable pawl (46) housed in the core (34) of the wrench (20) to provide a low-friction mechanism by which the pawl (46) is positioned to establish a selectable drive direction of the wrench (20) through simple one-finger displacement of the reversing plate (60).

Abstract: Polyorganosiloxane having the substructure
      where R⁸ is a divalent group generated by an addition reaction between SiH and acryloxy, methacryloxy, or alkenyl group and R⁹ is acryloxy, methacryloxy, or alkenyl, is prepared by an addition method in which an organopolysiloxane having two kinds of unsaturated groups selected from acryloxy, methacryloxy, and alkenyl and organohydrogenpolysiloxane are reacted in the presence of a platinum-type catalyst. These organopolysiloxanes are prepared without gelation and the method is highly efficient. 
     Radiation-curable compositions based on the polyorganosiloxane are characterized by a rapid cure upon exposure to radiation, while resisting curing inhibition even in the presence of oxygen, to give a cured material whose cured surface is slightly subject to time-dependent changes, and in particular whose peeling or release force undergoes little variation with the passage of time.

Abstract: An optical directional coupler switch is fabricated from a semiconductor substrate having a (111) plane. Thus, refractive indexes are changed for TE and TM modes by electrooptic effect, although the change amount is different between TE and TM modes. Therefore, a switching operation is realized for an incident light having any polarization. A device length L is preferrably set to meet an equation of "LTE ≦ L ≦ LTM" (L TE  and L TM  are coupling lengths for TE and TM modes) to decrease a cross-talk, even if the coupling lengths are different between TE and TM modes, considering that the difference is small.
