Title: Ring laser gyro
Inventor: NAKAMURA SHIGERU
IPC: H01S3/083
Filed: 1988-12-29
Abstract: PURPOSE:To accurately detect only an angular velocity signal to be measured by attaching a partly reflection-coated parallel glass plate to the back face of a mirror for an output mirror of mirrors. CONSTITUTION:A parallel glass plate 10 partly having reflecting films 10A, 10B is attached to the back face of a mirror 2-3. A laser beam L2 traveling counterclockwise is repeatedly reflected in the parallel glass plate 10 by the operation of the reflecting films 10A, 10B to displace the emitting position of the laser beam L2. In this case, even if a dither unit is disposed at the center of a glass block, frequency difference generated between the laser beams L1, L2 traveling clockwise and counterclockwise due to Sagnac effect and frequency difference generated due to Doppler effect are opposite in directions with the same magnitude by suitably selecting the refractive index and thickness t1 of the parallel glass plate 10. The output of a photodetector 8 is completely erased at the signal due to the dither. Thus, only the angular velocity to be measured can be accurately detected.

Title: Surface emitting device and its driving method
Inventor: MORIGUCHI TOSHIO
IPC: G02F1/1368
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To restrain the power consumption of a battery power supply, by reducing or interrupting the power supply to a light emitting element at every emission wavelength. SOLUTION: When detected power supply residue is at most 1/10 of the full charged state of a secondary battery, the stored power residue is judged to be little, and a comparing means 103 outputs an alarm pulse. A controlling means 104 in which the pulse is inputted turns out an LED for emitting a blue light from a white light surface light source for emitting all RGB lights, and only the green and the red LED's emit lights, so that the surface light source is changed to a surface light source for emitting an orange light. Thereby consumption power is reduced. When the power supply residue is at most 1/20 of the full charged state, the stored power residue is judged to be very little, and the comparing means 103 outputs an alarm pulse.  The controlling means 104 in which the pulse is inputted, turns out the LED for emitting a green light from the surface light source for emitting the RG lights making the orange light. As the result, the surface light source is changed to a surface light source for emitting a red light. Thereby the consumption power of the battery power supply can be reduced when the power supply residue is very little.
