Patent JP-S60249171-A (JP)
Title: Image forming method
Inventor: HANEDA SATORU
IPC: G03G21/00
Filed: 1984-05-25
Abstract: PURPOSE:To constitute a device in such a manner that a toner can be stuck to an electrostatic latent image without scattering or wasteful consumption by changing a bias voltage so as to decrease the max. voltage having the same polarity as the polarity of the potential in a background part during the time when the potential surface of the background part passes the developing region after the electrostatic latent image passes the developing region. CONSTITUTION:When a switch 12 of a rectifier circuit is turned on to a bias power source 11, the bias consisting of the superposed DC voltage and AC voltage impressed to a developing sleeve 51 thus far is converted to an impulsive bias voltage and said voltage is so changed that the max. voltage having the same polarity as the polarity of the potential in the background part decreases. The force of the electric field in the developing region A trying to scatter the toner from the developer layer and to stick the toner to an image forming body 3 is thus surely weakened during the time when the non-image electrified region of the body 3 passes the region A. The toner is consequently returned to the developer layer by the repulsive force in the non-image electrified region of the body 3 and therefore the wastefull consumption of the toner as a result of the sticking to the region except the image forming region and the scattering of the toner are prevented.

Title: Method for discriminating deterioration of hydraulic fluid
Inventor: HAMADA YOSHINORI
IPC: G01N33/28
Filed: 1994-05-19
Abstract: PURPOSE:To easily measure the degree of deterioration of a hydraulic fluid by finding the hue value of the hydraulic fluid and discriminating the deterioration of the hydraulic fluid from the hue value. CONSTITUTION:A light emitting section 1 and light receiving section 2 are arranged so that the sections 1 and 2 can be faced to a sample container 4 containing a hydraulic fluid 3 to be measured. After a processing section 7 processes a signal from the section 2, an outputting means 8 displays a digital hue value as the numerical value corresponding to the hue of the fluid 3. A detection circuit 5 converts the intensity of received light into a frequency. A control circuit 6 outputs the pulse number corresponding to the deterioration of the fluid 3 as the hue value after converting the numerical value converted into the frequency into the pulse number through arithmetic processing. The optimum wavelength corresponding to the hue value of the fluid 3 is decided from the relation between the light absorptance and hue value of the fluid 3 when the wavelength is changed to 420-660nm. The optimum length of the optical path is 4mm. When the wavelength and optical path length are set in such a way, the deterioration of the fluid 3 can be detected with high accuracy even when the amount of the fluid 3 collected in the container 4 is small.
