Title: Magnetic flux densitometer
Inventor: NAKAYAMA TAKASHI
IPC: G01R33/02
Filed: 1989-03-03
Abstract: PURPOSE:To display information corresponding to occasional magnetic flux density on a display means by providing a detecting means which outputs an electric signal corresponding to the magnetic flux density. CONSTITUTION:When a switch 20g for the peak value measurement mode and real measurement mode for the magnetic flux density is turned on, an arithmetic processing circuit 30 executes a magnetic density measurement routine repeatedly. Then an arithmetic processing circuit 30 fetches the signal supplied from an A/D converter 24 as current magnetic flux density to decide the polarity of magnetic flux and then generates display data according to the polarity of the inputted signal and data stored in a storage circuit 26, thereby outputting the display data to a display device 18. Consequently, a numeral corresponding to the current magnetic flux density, a scale for a bar graph, and the polarity of the magnetic flux are displayed visually on the display part as long as a flag corresponding to the switch 20g is reset.

Title: Variable frequency oscillator
Inventor: KIKUCHI AKIRA
IPC: H03B5/36
Filed: 1990-03-01
Abstract: PURPOSE:To stabilize a supply voltage and to reduce the cost by dividing the supply voltage to apply it to a variable capacity element and changing the capacity value of the variable capacity element in such direction that the change of the output frequency of an oscillating circuit due to the variance of the supply voltage is cancelled. CONSTITUTION:A supply voltage VCC is divided by a resistance R7 and a variable resistor RV1 and is applied to a varactor diode D1. When the voltage VCC is increased, the reverse bias voltage of the diode D1 is reduced, and as the result, the capacity value of the diode D1 is slightly increased. Since  F/f0 ( F is the difference between an output frequency F and a resonance frequency f0 peculiar to a crystal oscillator XL) of an oscillating circuit 11 is inversely proportional to a load capacity C2, the frequency F is reduced by the increase of the capacity value of the diode D1. The resistor RV1 is adjusted to adjust the change proportion to the supply voltage of the diode D1, and an output frequency characteristic where the change of the output frequency due to the change of the voltage VCC is suppressed is obtained.

Filed: 1982-03-29
Abstract: PURPOSE:To stabilize the operation of the titled power supply circuit using a compact constitution by a method wherein a DC output voltage is detected, said DC output voltage is stabilized by supplying the detected output to a control coil, and when the DC output voltage exceeds the prescribed value, the DC output voltage is dropped.

Title: Electrophotographic recorder
Inventor: ANZAI MASAYASU
IPC: G03G15/22
Filed: 1981-04-06
Abstract: PURPOSE:To alleveiate or prevent occurrence of a fringe pattern due to light interference even when a photoconductive layer is exposed to a monochromatic light capable of causing light interference in a laser beam printer, by providing a light dispersion reflection layer on the substrate surface of a photosensitive drum. CONSTITUTION:Since laser beams are monochromatic light capable of causing light interference in a laser beam printer, the beams interfere in a photoconductive layer and forms a light fringe pattern, causing the fringe pattern in the electrostatic latent image and the developed image, too. The occurrence of the fringe patterns is most affected by the light reflected by the surface of a substrate 18. The interference fringes are prevented by providing a rough surface on the substrate 18 to form a light dispersion reflection surface free from brilliancy and disperse the light reflected by the substrate surface. Such a light-dispersing reflection surface can be formed by methods, such as subjecting an aluminum substrate surface to pear-skin anode oxidation treatment, or causing minute grain roughness by sand blasting.
