The present invention relates to a solar cell module which is characterized in that: a light-transmitting elastomer member and a solar cell element are arranged in a space between a panel of a transparent member upon which sunlight is incident and a panel of a thermally conductive member which is arranged on the side opposite to the sunlight incidence side in such a manner that the light-transmitting elastomer member is closer to the sunlight incidence side; and the solar cell element is pressed by the light-transmitting elastomer member toward the panel of a thermally conductive member so that the solar cell element is compression bonded thereto. This solar cell module is most suitable as a solar cell module that has excellent heat dissipation of a cell, the temperature of which is increased due to sunlight or a hot spot, and a structure that suppresses the production cost.

A tricalcium-phosphate-based prosthetic material is disclosed, which is a sintered ceramic body mainly consisting of tricalcium phosphate containing a limited amount of zinc, which is a known element having an osteogenesis-promoting effect, in the form of a solid solution. By virtue of the limited content of zinc and the form of solid solution in which zinc is contained, the inventive material exhibits an osteogenesis-promoting effect without toxicity. The ceramic body is prepared, preferably, by a process in which a tricalcium phosphate powder containing 0.015-8.00% by weight of zinc is diluted by the addition of hydroxyapatite and/or tricalcium phosphate free from zinc in such a proportion as to give a (Ca+Zn)/P molar ratio of 1.55 to 1.65 and the powder blend is shaped and subjected to sintering.

摘要:
An irradiation apparatus with high energy electrons is disclosed in which a wire shaped or linear object to be irradiated is moved back and forth many times under an electron window so as to irradiate it with an electron beam. According to one feature of the invention, an electron beam, which leaks through gaps between the objects to be irradiated or which penetrates the objects to be irradiated, is reversed by a magnetic field approximately perpendicular to the scanning face of the electron beam by means of a magnet which is disposed under the objects to be irradiated, and the reversed electron beam is thereby again applied to the objects to be irradiated. A high utilization rate of the electron beam is accomplished, and the objects can be thereby uniformly irradiated with the electron beam.
