摘要:
A complex crystal phosphor is an inorganic composition containing at least an M element, an Al element, silicon, oxygen, and nitrogen. The inorganic composition has particles having at least two types of crystal phase, and the at least two types of crystal phase include a first crystal phase which is the same as a M2SiO4 crystal and a second crystal phase as a β-sialon crystal. Here, M is at least one element selected from the group consisting of (Mg), calcium (Ca), strontium (Sr), and barium (Ba).

The present invention provides a fire safety apparatus for a high-pressure gas storage system which can suitably ensure the fire safety of the high-pressure tank. Preferably, a flame transfer member having superior flammability is provided outside the high-pressure tank having a tank valve on a first end thereof. The flame transfer member extends a second end of the high-pressure tank to the tank valve, so that when a fire occurs, the flame transfer member rapidly burns creating flames and transfers heat from the origin of the fire to a PRD (pressure relief device) provided on the tank valve.

A base station is capable of transmitting a signal in a wireless communication network. The base station decides channel state information matrices of respective channels by determining a state of the channels corresponding to respective transmission antennas. The base station calculates transmission beam forming vectors for the respective transmission antennas by a combination of a dot product and a cross product of the channel state information matrices. Thereafter, the base station beam-forms signals for the respective transmission antennas by using the respective transmission beam forming vectors, and transmitting the beam-formed signals.
