Title: Method of stabilizing laser wavelength
Inventor: YASUDA KENICHI
IPC: B23K26/00
Filed: 1988-01-13
Abstract: PURPOSE:To stabilize a wavelength and to decrease variation in laser output, by utilizing two etalons so that one is controlled from a result of spectral diffraction of a laser beam while the other is controlled from laser power. CONSTITUTION:A divergent component produced from a laser beam by an integrator 12 is spectrally diffracted by an etalon 13 and one-dimensional distribution of optical intensity is measured by an image pickup element. 15. The measured data is smoothened and subjected to image processing 16 to obtain a position (x) presenting a maximum intensity. The position (x) is compared with a designated positional coordinate (x0) corresponding to an indicated wavelength, and a fine control etalon 5 is controlled by means of a servo mechanism from a result of the comparison, so that the central wavelength lambdam2 in a transmitting region of the etalon is varied. The fine control etalon is regulated in this manner, whereby an oscillation wavelength of the laser can be held fixedly. A part of the laser beam 6 is guided to a power monitoring mechanism 9. It is determined whether a laser output is increased or decreased when a rough control etalon 4 is controlled in either direction. The rough control etalon 4 is regulated by the servo mechanism 11 so that a maximum laser output can be obtained.

Title: Name card case, bill case and commutation ticket case
Inventor: ISHIWATARI SHOJI
IPC: A45C11/18
Filed: 1994-01-25
Abstract: PURPOSE:To enhance impression on a recipient of a name card by a method wherein a specified sound is outputted when the name card is pulled out to detect, and then, the outputting of the sound is stopped. CONSTITUTION:In a name card housing case, a plurality of detecting sections 3 are separated from a control section 4 for controlling the detecting sections 3 and the detecting sections 3 and the control section 4 are connected with a wire 5. When a name card 2 is pulled out of a guide part of the detecting section 3 and the pul ling of the name card 2 out of the guide part is detected with an electric contact part 6, a sound is outputted with an enunciation body of the control section 4. As a result, when the name card 2 is pulled out of the guide part of the detecting section 3 and handed to a recipient, a sound is emitted. So, the recipient of the name card 2 can receive the name card 2 under hearing the sound when the name card 2 is handed. Thus, when words of a greeting or the like are generated as voice. more intense impression is given to the recipient than the case when the name card 2 is handed plainly. This method also allows the creation of a playful frame of mind to the atmosphere by making it more gently on the spot.

Title: Optical beam scanning method
Inventor: SANOKI KEIKO
IPC: G02B26/12
Filed: 1978-01-24
Abstract: PURPOSE:To cause one polarized light due to a boundary of one rotating polyhedral mirror to be polarized twice on the other rotating polyhedral mirror, by using two rotating polyhedral mirrors, and rotating them in the same direction by applying a specified shift difference to the mutual rotation. CONSTITUTION:When a parallel incident beam 1 of beam diameter D enters a rotating polyhedral mirror 2a at a horizontal incident angle of delta, the optical axis is applied in the direction to form an angle of 2delta with respect to the incident beam 1, and the center of rotation of another rotating polyhedral mirror 2b is located on this optical axis. Thus, two rotating polyhedral mirrors 2a, 2b are disposed. In this constitution, while the light is polarized once at the angle of polarization of 2(alpha-beta) by one mirror plane of the rotating polyhedral mirror 2a, the light is polarized twice at the angle of polarization of 2(alpha-2beta) by the rotating polyhedral mirror 2b. Therefore, the number of optical beam scanning times may be twice as that obtained when the rotating speed of the rotating polyhedral mirror and the number of divisions are technically limited.

From a power supply time, fly-wheel 7 is rotated, and reciprocating material 25 is reciprocated by heart cam 24 to cause the first operating material 31 to advance. Accompanied with advance of material 31, the second operating material 24 receives the force of material 31 on the inclined face of linkage part 34b and is rotated with pin 35 as the center. Arm part 34c of material 34 strikes lock material 14 to release lock of pause level 2g. By this constitution, the electric means such as a solenoid can be needless to obtain the automatic pause release mechanism with the mechanical means.

Title: Acoustic flowmeter
Inventor: WALLEN LARS
IPC: G01F1/66
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To automatically identify a flow rate error by setting an error signal display device which outputs an error signal when a quantity derived from a propagation time value is different by a predetermined size from a control value. SOLUTION: Piezoelectric transceivers 7, 8 are arranged respectively at branches 3, 4 of a pipe 2 where a fluid flows. Sound wave pulses transmitted from one transceiver 7 traverse a flow passage of the fluid with a predetermined angle and are detected by the other transceiver 8. In this case, a propagation time Td in a downstream direction is obtained by a timing means 10. When the transceivers 7, 8 function reversely, a propagation time Tu in an upstream direction is obtained similarly. A microprocessor 11 obtains a flow rate of the fluid from the propagation times Td, Tu. An error signal display device 16 compares a quantity derived from the propagation times Td, Tu (a sum or difference of the propagation times Td, Tu) with a corresponding control value and outputs an error signal if the comparison result exceeds a predetermined threshold value.
