Title: Light control method and its device
Inventor: TANAKA NORIO
IPC: G02F1/17
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To extract a photo responsiveness of ample magnitude and speed from a photo responsive optical element with a good reproducibility. SOLUTION: Light sources 1, 2 emit control light and signal light respectively. These kinds of light are converged by a condenser lens 7 to irradiate an optical cell 8 packed with photo responsive liquid composition, only the signal light is detected by a photodetector 22 through a light receiving lens 9 and a wavelength selection transmission filter 20. The on/off action of the control light increases/decreases reversibly the transmission factor and/or refractivity of the signal light to realize the intensity modulation of the signal light. By setting the numeral aperture of the light receiving lens 9 at a value substantially smaller than that of the condenser lens 7, the light response of ample magnitude and photo responsiveness can be extracted from a light responsive liquid composition including a dyestuff packed in the optical cell 8.

Title: Power source controller
Inventor: MAEDA AKIRA
IPC: H02J1/00
Filed: 1994-10-04
Abstract: PURPOSE: To select control over the supply and cutoff of a power source or control over its output voltage by providing a means which forcibly turns ON a transistor(TR) and making its output ineffective, and providing a means which forcibly turning OFF a TR. CONSTITUTION: When an H signal is inputted to an ON/OFF terminal 7, the base voltages of TRs Q5 and Q6 go up to an H level and the TRs Q5 and Q6 turn ON. Therefore, the base voltage of a TR Q3 goes down to an L level and the TR Q3 turns OFF. Further, the base voltage of a TR Q2 also falls to the L level and the TR Q2 turns OFF. Consequently, a resistor R1 has no voltage drop and a voltage control TR Q1 is held OFF, so that an output voltage to a load becomes 0V. Then when an L signal is inputted to the ON/OFF terminal 7 and an H signal is inputted to a switching terminal 6, the TR Q3 turns ON and the voltage control TR Q1 is always in the ON state through similar operation. The output to the load, therefore, becomes 12V at all times.
