    摘要: There is disclosed a method of preparing cyclic silyl enol ethers (1-oxa-2-sila-5-cyclohexenes), comprising reacting a silacyclobutane with an acid halide in the presence of a palladium catalyst and an organic base. There is also disclosed novel cyclic silyl enol ethers obtained by the above method. The above cyclic silyl enol ethers belong to a new class of silyl enol ethers which are useful in the production of medicines and agricultural chemicals, and they can be used as intermediates of fine chemicals or as various reagents for fine synthesis.

    摘要: A method and apparatus for forming a Y-shaped wire harness (23) having a pair of wires (2,3) and for orientating the wires (2,3) in a specific orientation. More particularly the apparatus includes jaws (12) for orientating the wires (2,3), an identification member (14) for holding the wires (2,3) in that orientation during termination of one ends thereof and a guide member (18) for receiving and storing the wire harness (23) with the wires (2,3) in the specific orientation.

    摘要: An information processing apparatus includes a main base and a drive base on which support frames are erected to face each other. A pair of parallel guide shafts are supported on the frames and extend in the radial direction of an optical disk. An optical head is supported by the guide shafts to be movable along the shafts. Insulating tape is wound around each end of the guide shaft to electrically insulate the head from the base, thereby preventing external noise from being transmitted to the head via the base. The drive base is further insulated from the main base by insulating seals interposed between the main base and the drive base and by insulating collars through which screws attach the drive base to the main base.
