Title: Production of hydrogen
Inventor: SHIOJIMA ISAO
IPC: B01J31/16
Filed: 1983-05-12
Abstract: PURPOSE:Ascorbic acid represented by a specific structural formula is irradiated with visible rays in the presence of a catalyst of a rhodium complex and a ruthenium complex to produce hydrogen, as the deterioration of the catalyst and the decomposition of the substrate are inhibited. CONSTITUTION:In the presence of a rhodium complex such as chloronorbornadiene rhodium I dimer and dichlorotris(bipyridyl)ruthenium hexahydrate, ascorbic acid of the structural formula is irradiated with visible rays of about 380-800nm to cause the conversion of photoenergy into chemical energy to produce hydrogen. In the process of the present invention, the amount of the rhodium complex is about 0.02-2mM and that of the ruthenium complex is almost the same equivalent. The use of an ethylene carbonate-water mixture as a solvent inhibits the decomposition of the substrate and enables the high-efficiency utilization of the irradiated light. It is preferred to effect the above reaction in the coexistence of an amine such as triethanolamine, because the efficiency of the hydrogen production is increased.

Title: Level detecting device
Inventor: YAMAGUCHI CHIKATSUGU
IPC: G01F23/26
Filed: 1992-04-03
Abstract: PURPOSE:To obtain a level detecting device with the simple structure, which has the excellent linear characteristic between the level change of the liquid and the voltage change of the output signal. CONSTITUTION:The alternating voltage output from an oscillating circuit 1 is applied to a series circuit of an impedance element 7 and a level detecting capacitor 6, and a difference of the electric potential of both ends of the impedance element 7 is differentially amplified by an amplifying circuit 3. The other end of the level detecting capacitor 6 is grounded. In the case where the impedance of the impedance element 7 is represented by Z an the electrostatic capacity of the level detecting capacitor 6 is represented by C and the angular frequency is represented by omega, the linear characteristic of the voltage of the signal output from the amplifying circuit is improved by setting omegaCZ as smaller as possible than 1. Since one electrode of the level detecting capacitor 6 is grounded, the generation of over-lap of the high frequency noise with the signal voltage and the fluctuation of the direct current level of the signal voltage are reduced.

Abstract: PURPOSE:To compensate the fluctuation of input voltage with a small size structure by controlling the output of an inverter energizing a discharge lamp to keep constant using a means varying the output of the inverter stepwise. CONSTITUTION:When a controller 30 is controlled with outer control signals, turned on state of an FET 27 in a impedance device 20 is changed to control the turned on duration of a transistor(TR) 5, the output of an inverter device 1 energizing a discharge lamp 2 is varied stepwise.
