Title: Electronic apparatus with solar cell and control method therefor
Inventor: DAITO MASAYUKI
IPC: G04G99/00
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain a wrist watch excellent in design which can be charged efficiently even if a solar cell is arranged at the display part by providing a control means for bringing a liquid crystal shutter into transparent state when the wrist watch is required to be charged. SOLUTION: An amorphous solar battery 1 comprises a series connection of solar cell elements 1a-1d each comprising a laminate of a rear electrode layer, an amorphous silicon semiconductor layer and a transparent conductive layer formed on a substrate and the light enters from the transparent conductive layer side. A liquid crystal shutter 2 transmits the light when it is transparent because no voltage is applied but shields the light when it is rendered opaque by applying a voltage. When a secondary battery is required to be charged with the output from the solar battery 1, the liquid crystal shutter 2 is not applied with a voltage and transparent and thereby the light impinges on the solar battery 1 to generate power.  When the secondary battery is not required to be charged, the liquid crystal shutter 2 is applied with a voltage and rendered opaque thus reducing power generation of the solar battery 1.

In the process, a reaction product gas containing the resultant methacrylic acid is cooled and condensed to afford an aqueous solution of the methacrylic acid, which is then extracted and/or distilled to separate water and give crude methacrylic acid. The resultant crude methacrylic acid is then brought into contact with an aqueous solution of a bisulfite in the presence of a water-soluble organic solvent, e.g. benzene or n-hexane, to remove inpurities. The impurities, e.g. high-boiling aldehydes or protoanemonin, form an adduct with the bisulfite. Thus, the methacrylic acid is purified.

Abstract: PURPOSE:To impress a stable DC high voltage to an APD (avalanche photodiode) by controlling all 'H', 'L' levels of an output pulse signal of an oscillating circuit. CONSTITUTION:An output pulse signal (b) of an oscillation circuit 1 is given to an AGC control circuit 2 and the 'H' level is controlled by a detection signal (p) of the amplitude of an output signal (q) to form a pulse signal b'. Then a level setting circuit 30 inputs the signal b' via a transistor(TR) 31 and to give a current to a TR 32 to apply a voltage V0 to the signal b'. The voltage V0 is a potential lower by the base-emitter forward potential of the TR 32 than the potential V decided by a Zener diode 41 and a resistor 42.
