Filed: 1992-04-24
Abstract: PURPOSE:To provide an optical apparatus wherein it is small-sized and lightweight as compared with conventional cases, its power consumption is low and it can provide a laser beam, scanning. CONSTITUTION:A laser beam which is radiated from a semiconductor laser 1 as a light source is passed through a collimator lens 2; it is changed to nearly parallel beams; a liquid-crystal plate 3 is irradiated with them. A plurality of strip-shaped transparent electrodes are formed in the liquid-crystal plate 3. An electrode to which a voltage is to be applied is selected from the electrodes; the voltage is applied to the electrode; the polarization direction of a liquid crystal is changed; its transmission factor is lowered partly. As a result, an arbitrary grating pattern 4 can appear. When the laser beam is passed through the grating pattern 4, the laser beam is subjected to diffraction which is decided by the pitch of the grating. Thereby, the laser beam scanning is possible.

Title: Checking device for coupling
Inventor: ENDOU TAKASHI
IPC: G01N29/04
Filed: 1979-08-22
Abstract: PURPOSE: To check the coupling state of a coupler with high accuracy independently of the shape of a to-be-examined piece, by using rays of light to check the coupling state.  
     CONSTITUTION: Rays of light 18a are introduced from a light source 17 into a coupler 12. When air or the like is not mixed in the coupler 12, the introduced rays of light 18a are reflected on the surface of a to-be-examined piece 11. Since the reflexibility of the piece 1 is not equal to 1, the rays of light are attenuated due to the reflection. The reflected rays of light transmitted again through a wedge 10 and received by a reception element 19. When an air bubble is mixed in the coupler 12, the introduced rays of light 18a are totally reflected on the surface of the bubble so that intense reflected rays of light 18b are received by the reception element.

Title: Automatic output level control system
Inventor: YAMAGUCHI SEIICHI
IPC: H03G3/20
Filed: 1988-04-30
Abstract: PURPOSE:To improve convergence properties for control by approximating the control voltage-output power characteristics of a power amplifier with a straight line to define the characteristics to be stored in a P-V table. CONSTITUTION:A CPU 12 reads the control voltage shown in the digital value out of a P-V table 19 in accordance with the digital value showing the output power set via a serial port 17 and applies said control voltage to a power amplifier 11 via a I/O register 18 and a D/A converter 14. Thus the amplifier 11 amplifies the main signal and produces the output. Then the characteristics defined by approximating the outside of a control range of the actual control voltage-output power characteristics with a straight line obtained by extending the characteristics inside the control range is set to the table 19. As a result, the control convergence properties are constant even in case the output voltage of the amplifier 11 is kept at a point near the saturated part of the control voltage-output power characteristics close to the upper limit value of the control range. Thus it is possible to improve the control accuracy and to shorten the converging time.
