Abstract: PURPOSE:To enable execution of acoustic-wave measurement being sensitive sufficiently to a modulated light for measurement modulated at a specific wavelength and sensitive to a sound pressure, by providing an acoustic-wave measuring piezoelectric body stuck on a cylindrical resonator into which a measuring tube is fitly inserted. CONSTITUTION:When a modulation signal is oscillated from a modulation signal generator 42, a laser diode driver 43 drives a laser diode 45 and a laser light is emitted from the diode 45. The laser light is applied to the position of the antinode of an acoustic wave in a photoacoustic cell 30 wherein a sample liquid 20 is stored. In this case, the sample liquid 20 generates a heat with absorption of the light, a periodic heat current is brought forth and thereby the sample liquid 20 is made to vibrate. With the vibration of the sample liquid 20, a resonator 38 resonates and a piezoelectric member 40 converts this vibration into an electric signal. Moreover, the electric signal is amplified by a preamplifier 47 and subjected to a prescribed signal processing 48 through a lock-in amplifier 44. This constitution enables execution of acoustic-wave measurement being sensitive sufficiently to a modulated light for measurement modulated at frequencies of several tens of KHz to several MHz and sensitive to sound pressure.

Abstract: PURPOSE:To prevent a light emission part from being pressed in by unexpected operation during photography by providing an engagement part which engages a storage-side lock means and an engagement part which engages a projection- side lock means at part of the light emission part. CONSTITUTION:A surface 1d of the light emission part 1 engages the lock surface 2d of a lock claw 2 to hold the light emission part 1 at its storage position, so when the light emission part 1 is disengaged from the lock claw 2 by moving a release plate 6 left, the light emission part rotates clockwise around a shaft 1 with the force of a spring 5 to project. Even when the light emission part 1 is pressed down, a lock part 8a inhibits the light emission part 1 from moving down, but when the light emission part 1 is moved right, the shaft 1a moves back to the right end of a long hole 4a to disengage the lock part 8a. When the light emission part 1 is rotated counterclockwise in this state, the slanting surface 1c of the engagement part abuts on the slanting surface 2b of the lock claw 2, which is moved left to lock the surface 1d of the light emission part 1 by the lock surface 2d, so that the light emission part 1 is put back into the storage state.

Inventor: TAKAHASHI KENJI
IPC: H02K9/06
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To reduce the temperature of a stator or rotor by increasing the thickness of only a frame part which is brought into contact with the stator. SOLUTION: The thickness of a frame 10 is partially changed in a shaft direction for thickening merely a part in contact with a stator 9, and the thickness of a part other than the stator 9 is thinned, thus eliminating the support of deformation even when the diameter of the stator is increased to prevent deformation of the frame 10, and obtaining high heat conductance. For fixing the stator 9 and the frame 10, the frame 10 is heated once subjected to thermal expansion for inserting the stator 9, and assembly can be made even if a part other than the outer diameter of the stator 9 is large, thus reducing not only the temperature of the stator 9 but also that of the rotor 8.  More specifically, the amount of heat of the stator 9 transferred to the frame 10 and, the amount of heat which flows into material air for cooling from the stator 9 is reduced by the amount of heat transferred to the frame 10, thus decreasing the temperature of the inside air and that of the rotor 8 is also reduced.
