Abstract: This invention relates to an electrophotographic copying and printing apparatus having copying function and printing function.

Abstract: The disclosure relates to a flexible ceramic bio-implant member comprising a bundled body of a plurality of ceramic fibers having flexibility and elasticity and bundled into a desired shape in the state of the fibers being allowed to make flexible movement. The bio-implant member is enabled to serve the purpose of flexible reinforcement of a conventional implant member by the use of this flexible bio-implant member in combination with the latter.

Abstract: A semiconductor integrated circuit supporter on which a heating element is dielectrically provided, said supporter comprising a package, printed circuit board, mother board, etc. for supporting a semiconductor integrated circuit which includes devices such as transistors.The heating element provided on said semiconductor integrated circuit supporter is capable of heating the whole or a required part only thereof so that the semiconductor integrated circuit is preheated to a temperature required for its normal operation with precision and stability thereby improving the accuracy and reliability of various devices of which a semiconductor integrated circuit is composed as well as the control by said devices.

Abstract: This invention relates to a golf club head capable of increasing the flying distance of the ball hit in a substantial degree, imparting a refreshing feeling of ball hitting to the player and being manufactured at low cost and durable for long time use by fixing the striking face of the club head with a ceramic face plate made of a sintered body of metallic oxides such as alumina ceramics, mullite ceramics, etc.
