A fluorescent lamp includes a glass container (204) having mercury enclosed therein, and a phosphor layer (202) formed on an inner side of the glass container (204). The phosphor layer (202) includes phosphor particles (202a) and rod-shaped bodies (202b) composed of a metal oxide and spanning between the phosphor particles. The rod-shaped bodies (202b) have a thickness of, for example, 1.5 [μm] or less. Pairs of adjacent phosphor particles may be spanned by more than one rod-shaped body.

A fluorescent lamp (20) includes a glass bulb (30) that has mercury enclosed therein, and a phosphor layer (32) formed on an inner side of the glass bulb (30). The phosphor layer (32) includes three types of phosphor particles, which are red phosphor particles (32R), green phosphor particles (32G) and blue phosphor particles (32B) that are excited by ultraviolet radiation to emit red light, green light and blue light respectively. The blue phosphor particles (32B) and green phosphor particles (32G) have a property of absorbing ultraviolet radiation with a wavelength of 313 nm.

A recombinant BCG vaccine being transformed with an expression vector that has a polynucleotide encoding a foreign antigenic protein, wherein the polynucleotide is a modified one in which the third position of each codon is substituted with G or C without a change of an amino acid. This recombinant BCG vaccine has an excellent expression rate of antigenic protein and, as a result, capable of inducing a sufficient immune response against target infectious disease, cancer, or the like at the same dose as that of the typical BCG vaccine.

A backlight unit has an external electrode fluorescent lamp in a housing. The external electrode fluorescent lamp includes a glass bulb having a discharge space inside, and electrodes around both ends of the glass bulb. A protective layer and a phosphor layer are formed on an internal surface of the glass bulb in this order. The glass bulb is made of soda glass, and sodium oxide precipitated from this soda glass appears on part of the internal surface of the glass bulb where the protective layer is not formed, so as to be exposed to the discharge space.

A needle 2 includes a plunger member 21 and a collar member 22, and is provided to be reciprocable from a latch position to a latch release position inside a stator 1. A first magnet coil 31 has sufficient electromagnetic power to put in a latch state the needle 2 which is in a latch release state on energization. A permanent magnet 4 has sufficient absorption power for absorbing a collar member 22 of the needle 2 put in the latch state by the electromagnetic power of the first magnet coil 31 and maintaining the latch state even when the first magnet coil 31 is in a non-energized state. A second magnet coil 32 can diminish magnetic fluxes of the permanent magnet 4 and change the needle 2 from the latch state to the latch release state on energization. Thus, energy efficiency is improved by varying how to energize the magnet coils according to the state of a load side.

An electronic device has a frame and a back board having plural logical units and power supply units mounted thereon. The logical units and the power supply units are alternately located on both sides of the back board in the center of the frame so that the power supply units mounted on one side of the back board may feed a power to the closest logical units mounted on the other side. Further, the air flow paths to be circulated through the logical units and the power supply units are formed so that each unit may be efficiently cooled by the air fed by an air fan unit. As a result, the feeding voltage becomes uniform and the cooling efficiency is improved.
