摘要:
A carbonaceous acoustic diaphragm whose density is reduced while retaining the required stiffness is provided. Carbon nanofibers and spherical particles of PMMA are mixed into a carbon-containing resin such as a polyvinyl chloride resin, and the mixture is carbonized to vaporize the spherical particles of PMMA, thereby forming a porous structure having pores with the carbon nanofibers in a powdered form uniformly dispersed through amorphous carbon. By forming a multilayer structure by combining the porous layer with a layer that does not use PMMA, the density can be further reduced while retaining the stiffness.

摘要:
A method is disclosed with provides stable growth of SiC single crystals, particularly 4H—SiC single crystals, with an effective crystal growth rate for a prolonged time even at a low temperature range of 2000° C. or lower. A raw material containing Si, Ti and Ni is charged into a crucible made of graphite and heat-melted to obtain a solvent. At the same time, C is dissolved out from the crucible into the solvent to obtain a melt. A SiC seed crystal substrate is then brought into contact with the melt such that SiC is supersaturated in the melt in the vicinity of the surface of the SiC seed crystal substrate, thereby allowing growth and production of an SiC single crystal on the SiC seed crystal substrate.

摘要:
Provided is a method of removing a cartridge, that is to be removed, that is housed in a deep side of a cell and stuck on a wall surface of the cell without increasing the number of components. In order to remove the cartridge stuck on the wall surface of the cell, the method includes a pressing step and a releasing step. In the pressing step, a picker mechanism is abutted on a latch lever, and then moved so as to move the latch lever from an engaged position to a released position. This presses the latch lever to increase the urging force of the urging unit. In the releasing step, after the pressing step, the picker mechanism is moved away from the cell to release the urging force of the latch lever spring.
