Provided is a feed material for epitaxial growth of a monocrystalline silicon carbide capable of increasing the rate of epitaxial growth of silicon carbide. A feed material 11 for epitaxial growth of a monocrystalline silicon carbide includes a surface layer containing a polycrystalline silicon carbide with a 3C crystal polymorph. Upon X-ray diffraction of the surface layer, a diffraction peak corresponding to a (111) crystal plane and a diffraction peak other than the diffraction peak corresponding to the (111) crystal plane are observed as diffraction peaks corresponding to the polycrystalline silicon carbide with a 3C crystal polymorph.

A hermetic compressor includes a thrust ball bearing (176) on the thrust face (160) of the main bearing (126). The thrust ball bearing (176) includes balls (166) held in a holder (168), an upper race (164) and a lower race (170) arranged respectively on and beneath the balls (166), and an elastic support member (172) below the balls (166). The hermetic compressor is prevented from causing a load to be applied unevenly to the balls (166), thereby achieving high efficiency, low noise level, and high reliability.

摘要:
A control system has an input instrument that generates a signal indicating permission and prohibition of running of a load, a power-supply unit that is configured to supply driving power to the load when the load is permitted to run by an input signal from the input instrument, and to cut off the supply of the driving power to the load when the load is prohibited from running by the input signal, and a monitoring device that is configured to monitor the input instrument and the power-supply unit. The power-supply unit is configured to cut off the supply of the driving power to the load when monitoring result of the monitoring device indicates an abnormality of one of the input instrument and the power-supply unit. The control system is compatible with category 2 of ISO 13849-1.
摘要:
This aims to provide a pulse laser welding aluminum alloy material, which can prevent the occurrence of an abnormal portion, when an A1000-series aluminum material is welded with a pulse laser, so that a satisfactory welded portion can be homogeneously formed, and a battery case. The pulse laser welding aluminum alloy material is made of an A1000-series aluminum material, and has a viscosity of 0.0016 Pa·s or less in a liquid phase. Alternatively, the pulse laser welding aluminum alloy material has such a porosity generation rate of 1.5 (μm2/mm) or less in the pulse-laser welded portion as is numerically defined by dividing the porosity total area (μm2), as indicated by the product of the sectional area and the number of porosities, by the length (mm) of an observation section.
