Title: Electrophotographic organic photoreceptor
Inventor: YAHAGI HIDETAKA
IPC: G03G5/10
Filed: 1995-05-26
Abstract: PURPOSE: To obtain a high image quality without producing fog or black spots by specifying the loss factor of a film between an aluminum body and an anodically oxidized surface, namely, by specifying the ratio of the reactance to the serial resistance. CONSTITUTION: This electrophotographic org. photoreceptor is produced by forming an org. photosensitive layer on an aluminum base body having an aluminum anodically oxidized film on its surface. The loss factor of the anodically oxidized film between the aluminum body and the surface of the film, namely, the ratio of the reactance (Xc) to the serial resistance (R) is specified to <=0.8. The ratio is the product of the serial resistance (R) of the anodically oxidized film and the capacitor (C) which constitutes the reactance (Xc), and namely, it is inverse of the product of the specific resistance and dielectric const. of the anodically oxidized film. Therefore, it is necessary that the serial resistance (R) and the capacitor (C) are larger than certain values.  Namely, when the photosensitive layer is charged, injection of charges from the aluminum base body is prevented by the anodically oxidized film and the injection current is suppressed small, so that the charge potential is maintained in a good state.

Title: Measuring method for material dispersion characteristic of fiber
Inventor: TOKUDA MASAMITSU
IPC: G01M11/02
Filed: 1979-10-01
Abstract: PURPOSE:To make it possible to separate and measure only the effect of material dispersion with high precision by halving light amplitude-modulated with a single sine wave, by causing them to strike optical fibers differing in length and by measuring a phase difference between detection signals by varying the wavelength of light. CONSTITUTION:Light from variable wavelength light source 1, when passing through external modulator 2, is amplitude-modulated with a high-frequency signal from electric signal generator 3. This modulated light is branched into two by branching filter 4; one is incident to optical fiber 5, and the other to optical fiber 6 differing in length from optical fiber 5. Lights having propagated in optical fibers 5 and 6 are converted into electric signals by detectors 8 and 9 and phase difference measuring instrument 9 measures the phase difference. Next, the wavelength of light source 1 is slightly varied to measure the phase difference again and the wavelength is sequentially varied to measure a phase shift to the wavelength, so that the effect of material dispersion will be obtained.

Each of heat storage tanks  is connected via a cooler 3, the 1st conduit 4 and a supplying port 5 having an electromagnetic  valve 6. And then, temperature of each heat storage tank 2... is detected by a detector 7 and  temperature of a cooler 3 is detected by a detector 9, thus, the difference of these two temperatures is operated through an arithmetic unit 8, and further, according to an order of a specified  program, with each heat storage tank 2..., the electromagnetic valve 6 is opened or closed in  order that the difference of temperature becomes zero, thus, the cold heat of the cooler 3 is stored.  In this way as shown above, the maximum heat storage quantity is stored with each (continued)  heat storage tank, as a result, the heat storage temperature is not averaged, thus, the temperature  from a cooler or a heater is stored as it is and efficiency can be improved.
