Filed: 1993-07-02
Abstract: PURPOSE:To provide the optical module which does not generate the deterioration in output occurring in dew condensation by adding a surface active film to the exposed surface of the optical parts of a laser output section. CONSTITUTION:This optical module has a surfactant layer 14 at the end faces facing each other of a first lens 6a and an optical fiber 10. Namely, the surfactant 14 is applied on the surface of the optical member exposed on the surface of this optical module or the surface is coated with the surfactant so that granular water drops having a significant optical influence are not generated even if the condensation of the moisture in the atm. air is generated by a temp. change, etc. The optical influence on an output, laser beam is thus extremely little. The surfactant described above refers particularly materials used for control of interfacial phenomena among the materials which exhibit extremely the surface activity at a low concn.

Title: Loudspeaker
Inventor: MURAOKA KAZUYUKI
IPC: H04R9/06
Filed: 1987-07-29
Abstract: PURPOSE:To equalize displacement moving to the front and rear directions of a diaphragm and to suppress the distortion of a voice output by specifying the curvature of a vibrating surface. CONSTITUTION:A sandwiching angle theta, between a straight line to connect the top of the vibrating surface formed in the curvature of a diaphragm 1 and the driving point of the vibrating surface, and a horizontal surface passing the driving point, is set in the range of 22.5+ or -7.5 deg.. When the angle theta is small, a difference between front direction displacement and rear direction displacement is large, and a distortion is generated. When the angle is large, though a symmetry becomes good, the absolute value of the displacement is made small and an efficiency is bad. In such a way, by setting the curvature of the vibrating surface, the displacement moving to the front and rear directions of the diaphragm 1 can be made equal, the relation of a sound output waveform to an electric input which is a sound signal is made linear, and the distortion of the voice output can be suppressed.
