    摘要: An addition reaction type silicone rubber composition for injection molding compounded with an azo compound, carbon black, and at least one of cerium hydroxide and cerium oxide is disclosed. Silicone rubber moldings having a small compression set and an excellent flame retardance are obtained without need of carrying out a postcure after primary molding. Further, integral molding of the silicone rubber and a thermoplastic resin can be carried out.

    摘要: A method and an apparatus for changing the sewing direction of a multiple needle flat sewing machine for sewing elbow pads of sports wear, jumpers, etc. and patchworks of various shapes. Needles are stopped at the needle upper dead center position; a throat plate is moved in a direction contrary to the sewing direction; a needle thread or looper thread caught on tongues of the throat plate is released from the tongues; and the sewing direction can be changed at any desired angle in relation to the sewing direction at the start, such as a right angle, an acute angle or an obtuse angle. The present invention also makes it possible to carry out fancy stitching with thick thread by a multiple needle flat sewing machine.

    摘要: A semiconductor switching circuit comprises an output FET receiving a photovoltaic output generated by a diode array responsive to a light signal from a light emitting element, a depression mode driving FET connected at the drain and source to the gate and source of the output FET, and a constant voltage conduction element connected in parallel with a resistor connected across the gate and source of the driving FET. The sensitivity of the circuit is elevated by setting the value of this resistor relatively high, whereas high speed operation can be assured by having discharge current of an accumulated charge across the drain and gate of the output FET bypassed through the resistor.
