    摘要: The present invention addresses the problem of obtaining a headphone type sound collector capable of selectively amplifying frequencies of sounds that are difficult for people with weak hearing to hear. As the means for solving the above-mentioned problem, the headphone type sound collector 1 of the present invention is a headphone type sound collector equipped with a sound collecting device 100a or 100b on at least either of the left and right sides thereof, the sound collecting device comprising: a sound collecting cover 110a or 110b having a sound collecting face in a parabolic shape for collecting sound; a base member 120 for pivotally supporting the sound collecting cover; and a microphone 130 for detecting sound collected by the sound collecting cover.

    摘要: The present invention relates to a fluorescent lamp, and in particular to a fluorescent lamp with an improved in-dark starting characteristic. A fluorescent lamp includes: a glass bulb (101) having a discharge space therein; two external electrodes (102 and 103) provided at both ends of the glass bulb; and a phosphor layer (106) provided on an inner surface of the glass bulb. The glass bulb is made of glass that contains 3% to 20% inclusive of sodium oxide. The phosphor layer includes phosphor particles (106R and 106G) containing no alumina and phosphor particles (106B) containing alumina. A metal oxide (107) is attached to surfaces of the phosphor particles containing alumina. Sodium oxide precipitated on the inner surface of the glass bulb improves the in-dark starting characteristic. The phosphor particles containing alumina are protected by the metal oxide for being susceptible to deterioration due to reaction thereof with sodium oxide.
