IPC: G01J1/48
Filed: 1992-06-30
Abstract: PURPOSE:To enable attaining strong potoelectric response to light incidence by putting a photoelectric conversion active layer and an electro transmission layer between a pair of electrodes. CONSTITUTION:On transparent base plates 1a and 1b formed of a pair of glass plates, and transparent electrodes 2a and 2b are formed and on the electrode 2a on the base plate 1a, a photo-electric conversion active layer 3 is formed using chromatophore suspension liquid. On the other hand, a thin plate electron transmission layer 5 is formed by adding and mixing an electrn transmission material having a function of transmitting electron to a water containing material, which 5 is overlaid on the active layer 3 formed on the electrode 2a. To this transmission layer 5, the electrode 2b on the other base plate 1b is faced and both transparent base plates are overlaid. Electrons generated in the active layer 3 due to photo-excitation move to the direction from the active layer 3 to the transmission layer 5. Therefore, electrons can be transmitted sufficiently from the active layer to the transmission layer and thus, photoelectric current response performance can be especially improved.

Title: Control method of number of revolution of air conditioner
Inventor: KAWAGUCHI YUJI
IPC: G05D16/20
Filed: 1985-08-07
Abstract: PURPOSE:To limit the pressure of a compressed gas to a fixed value or lower, and to improve the reliability of a compressor largely by bringing the detecting value of the DC currents of an inverter section within a limiting value changing ion the form of the linear expression of the number of revolution. CONSTITUTION:Input DC voltage V and input DC currents I are taken in by a control circuit 6, and inputted to an overload detecting circuit in the control circuit. On the other hand, drive signals N corresponding to the predetermined number of revolution are transmitted over an inverter section 3 by the control section 6. An output from the inverter is fed to an adjustable speed motor 4, and a compressor 7 is driven. DC currents are controlled within a limiting value, which can be described by the linear expression of the number of revolution of the compressor, thus keeping the pressure of a discharge gas within a prescribed value. Accordingly, the safety of a cycle can be improved largely while there is not trouble on actual application such as the lowering of capability even when the conditions of load and the conditions of input voltage change on heating operation, thus extremely suppressing a burden on the compressor.
