摘要： [PROBLEMS] To accurately tune the frequency of vibration by means of a suspension during assembly. [MEANS FOR SOLVING PROBLEMS] Securing planned positions (3e) where a magnetic circuit portion (2) is secured to a suspension (3) are provided near to each other. From among the securing planned positions (3e), a securing planned position (3e) corresponding to the characteristics of the suspension (3) to be mounted or the weight of the magnetic circuit portion (2) is selected, and they are secured to each other. Thus, the length from the securing position to the vibration center position of the suspension (3) and a housing (1) is varies so that the frequency may be tuned to a desired value.

摘要： A current measuring device comprising a current detector (10) and a photoelectric converter (20). The detector (10) is provided with an optical fiber sensor (11) installed to encircle the outer periphery of a conductor (30), and the sensor (11) is provided at one end side thereof with a reflection film (12) so as to effect reflection at the end thereof. The current detector (10) comprises a first Faraday element (13), a light-transmitting double refraction element (14), a first optical fiber (15), a second optical fiber (16), and a lens (17). The Faraday element turns the polarization surface of an incident light almost 22.5°. The double refraction element (14) has the functions of separating an output light from the sensor (11) into a normal light L1 and an abnormal light L2 mutually crossing perpendicularly, and transmitting linearly polarized light L0 emitted from a light source. The lens (17) is disposed between the element (13) and the double refraction element (14), with image forming points set at the incident end (11a) of the sensor (11) and at a core at one end surface (15a) of the first optical fiber (15). Accordingly, constituting parts are reduced in number to thereby reduce the size of the device.

摘要： [PROBLEMS] To provide a multi-function type oscillation actuator and a mobile terminal device capable of lowering the lowest acoustic resonance frequency and preventing a cut-off of a coil lead as well as improving acoustic characteristics and preventing sound leak. [MEANS FOR SOLVING PROBLEMS] A portion near to the outer circumference of a diaphragm (3) is bent to form a rising portion (3b) extending along an inner circumference (1a) of a housing (1) toward its open end. This rising portion (3b) serves as a corrugation to lower the lowest resonance frequency and the amplitude on the rising portion (3b) as a fulcrum is not large unlike the corrugation. Accordingly, the coil lead of a voice coil (4) is not broken easily. Furthermore, an extending portion (3c) is formed to extend along a flat surface (1b) formed at the open end of the housing (1) from the rising portion (3b) toward outside. This enlarges the entire radius of the diaphragm and improves the acoustic characteristic. Moreover, by arranging the flat surface (1b) of the housing (1) parallel to the extending portion (3c) of the diaphragm (3), a gasket or the like can easily be attached.

摘要： A plurality of platy optical elements, capable of downsizing an optical device by using an octagonal shape and being positively fixed to the inner bore of a permanent magnet by brazing, are efficiently cut out of a large-area platy optical material. Circular, round or oval, punched holes (11, 12...) with their centers located at the crossing points (P1, P2...) of dividing lines (C1..., C2...) dividing a platy optical material (10) laterally and longitudinally are formed in a plate surface, the plate surface of the optical material (10) provided with the holes (11, 12...) is cut laterally and longitudinally, and a plurality of platy optical elements each providing an almost octagonal outer shape formed by four each of alternately continuous linear sides and arcuate sides are obtained.
