In an afterglow fluorescent lamp having a structure wherein at least a phosphorescent phosphor layer is set on the internal surface of a glass container, pinholes are prevented from appearing in the layer. The layer is formed, using a phosphorescent phosphor powder, wherein a metal oxide powder whose primary particles have a particle-size distribution with an upper limit particle size smaller than a lower limit particle size of a particle-size distribution that primary particles of a matrix material of the phosphorescent phosphor powder have is mixed, in a ratio by weight that is not less than 10 wt % but not greater than 40 wt %, with the matrix material of the phosphorescent phosphor powder. Therein, the particles of the metal oxide fill the gaps among the particles of the phosphorescent phosphor, and thereby the adhesive strength between the particles of the phosphorescent phosphor is heightened.

Provided is a foamable filling device that includes a foamable material and is disposed within a hollow structural member. The foamable filling device includes a carrier member and an opening/closing member. The carrier member includes a through hole and a mounting portion to which the foamable material is mounted. The opening/closing member includes a cover portion formed in a size capable of blocking the through hole; and a biasing portion that biases the cover portion, and the opening/closing member is fittable to the carrier member. The opening/closing member is configured such that, when the opening/closing member is fitted to the carrier member, the biasing portion is elastically deformed and biases the cover portion to thereby bring the cover portion into contact with a seat portion provided at an end of the through hole of the carrier member.

A thin film micromechanical resonator (resonator) having improved drive efficiency, a resonator gyro having improved sensitivity in detecting an angular velocity, and a navigation system and an automobile using the resonator gyro. The resonator includes a tuning fork structure made of a non-piezoelectric material, and a first electrode and a second electrode disposed respectively at the inner side and the outer side of the tuning fork arm. On the first and second electrodes, a first piezo film and a second piezo film are provided respectively, and a third electrode and a fourth are respectively provided electrode thereon. When an alternating voltage is applied to the third and fourth electrodes at the opposite phases each other, the tuning fork resonates in the direction perpendicular to the center line. The resonator gyro detects, at the sensing section which is formed of another electrodes and another piezo film, the Coriolis force generated in proportion to angular velocity given to the resonator.
摘要:
A metal terminal has a terminal body (19) having a crimp part (5) crimped to a wire and a fastening part (25) connected to the terminal body (19) through breaking parts (21, 21). The fastening part (25) has a through-hole (23) for passage of a bolt (7). The metal terminal further includes a co-fastening part (27) formed in the terminal body (19). The tip side of the co-fastening part (27) is fastened to a vehicle body (13) by the bolt (7), together with the fastening part (25). When detaching terminal body (19) from the vehicle body (13), one side of the one terminal body (19) is pulled up in a direction opposite to the fastening direction of the bolt (7) under condition that the fastening part (25) and the co-fastening part (27) are together fastened by the bolt (7). Consequently, the co-fastening part (27) is released from its fastened condition and a breaking force is applied on the breaking parts (21, 21).
