Title: Packing of carbon heater for single crystal pickup and its formation
Inventor: KONO TADAYOSHI
IPC: B65D81/107
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To pack effectively utilizing the characteristics of a graphite material constituting a carbon heater, to eliminate the generation of an environmental problem such as the disposal of packing material including a cushioning material, to transport safely to a customer, and to make it easy for the customer to unpack. SOLUTION: The cylindrical end face of a cylindrical carbon heater 1 is held between a base plate 6 and a plurality of fixing panels 7, 8. With each part of the carbon heater on the base plate 6, the fixing panels 7, 8 are integrated by applying compression separately in a cylindrical axis direction. Because tensile stress cannot be applied and compressive stress only is applied in packing, the carbon heater is not damaged at all, and a space filler used for preventing breakage in packing becomes unnecessary. By this, a packing material can be reduced and the generation of industrial wastes can be eliminated.

Inventor: ANDO HIDEO
IPC: G11B11/105
Filed: 1988-12-27
Abstract: PURPOSE:To give a uniform magnetic field to accurately record or erase information without giving noise to an information recording medium by arranging a magnetic flux generating face in a position facing the surface of the information recording medium and constituting the peripheral part of the magnetic flux generating face so that it is distant from the surface of the information recording medium.
