  • Publication number: 20170214179
    Abstract: A male housing of a connector assembly has moving plate (30) with a pair of resilient locking pieces (34) that can be curved resiliently and deformed to incline a projecting direction of the resilient locking pieces (34). A female housing (50) causes the moving plate (30) to interfere with initial position holding projections (18) and pulls the moving plate (30) back to an initial position by locking with locking portions (55) to the resilient locking pieces (34). The initial position holding projections (18) are paired and spaced apart in the same direction as a separating direction of the resilient locking pieces (34) and are arranged at positions different from the resilient locking pieces (34) in the separating direction of the resilient locking pieces (34).

  • Publication number: 20170214180
    Abstract: A moving plate (30) includes two resilient locking pieces (34) and can be resiliently curved and deformed to incline a projecting direction of the resilient locking pieces (34), and a female housing (50) pulls the moving plate 30 back to an initial position by locking locks (55) to the resilient locking pieces (34). With the moving plate (30) held at the initial position by initial position holding projections (18), the locks (55) of the female housing (50) are displaced to locked positions to the resilient locking pieces (34) by resiliently deforming the resilient locking pieces (34). The initial position holding projections (18) are spaced apart in the same direction as a separating direction of the resilient locking pieces (34) and arranged at positions different from the pair of resilient locking pieces (34) in the separating direction of the pair of resilient locking pieces (34).

  • Publication number: 20160160386
    Abstract: A silicon carbide powder which, when used as a raw material in a sublimation recrystallization method, enables improvement in productivity of a silicon carbide single crystal by exhibiting a high sublimation rate and allowing a small amount of silicon carbide to remain without being sublimated, and enables an increase in size of the silicon carbide single crystal (for example, a single crystal wafer). The silicon carbide powder has a Blaine specific surface area of from 250 cm2/g to 1,000 cm2/g and a ratio of a silicon carbide powder having a particle size of more than 0.70 mm and 3.00 mm or less of 50 vol % or more with respect to a total amount of the silicon carbide powder. When a silicon carbide powder accommodated in a crucible is heated to be sublimated, a silicon carbide single crystal is formed on a seed crystal provided on an undersurface of a lid.

  • Patent number: 9357971
    Abstract: An X-ray CT photographic apparatus including: a beam shaping mechanism that regulates an irradiation range of an X-ray generated from an X-ray generator and shapes the X-ray into an X-ray cone beam; and a main body controller that changes a read region, where an X-ray detection signal is read in the X-ray detector, according to the irradiation range of the X-ray cone beam. The main body controller changes the irradiation range of the X-ray cone beam to an x-axis direction during an X-ray CT photography such that only a set CT photographic region is irradiated with the X-ray cone beam according to the set CT photographic region input through a CT photographic region setting unit. The main body controller changes a read region in an X-ray detector with respect to the x-axis direction in a detection surface of the X-ray detector during the X-ray CT photography.
