Filed: 1987-02-23
Abstract: PURPOSE:To permit surface potential control of a photosensitive body with high accuracy and to obtain a high-quality image with decreased fluctuation in the image density by measuring the surface potential of the photosensitive drum in a specific rotating position and controlling said potential to maintain the specified surface potential. CONSTITUTION:The surface potential control of the photosensitive drum 11 is executed by projecting laser light L to the drum 11, measuring the potential VL in the bright part of the drum 11, determining a difference between the resulted VL value and the target VL value and computing the amt. of increasing or decreasing the quantity of the laser light necessary for correcting the difference. The measurement of the potential VL value in the bright part is executed at all times during one rotation of the drum 11 and the min. VL value among the resulted VL values is used as measurement data. The uneven sensitivity characteristic of the drum 11 has the characteristic intrinsic to said drum in production and, therefore, the adoption of the min. VL value as the measurement data eventually leads to the specification of the position of said drum. The measurement of the VL value is thereby executed always at the specified place of the drum 11 and the potential control with high accuracy is permitted.

Filed: 1986-02-24
Abstract: PURPOSE:To halve a word length and at the same time to obtain a detection value with high accuracy by omitting the arithmetic for 4-square order of the envelope curve value. CONSTITUTION:Numerical converting circuits 3A and 3B supply the outputs rMAX and rMIX of the maximum and minimum value holding circuits 2A and 2B respectively. If these output values are equal to the logarithm compressed value of a reception envelope curve, they are converted into original linear values or the numerical conversion outputs RMAX and RMIN of the squared values of said linear values. The averaging circuits 4A and 4B supply the outputs RMAX and R MIN every time a short section pulse T1 rises up to 'H' from 'L' and then delivers the mean values RMAX and RMIN of the sample value of M pieces of RMAX or RMIN for each short section of a prescribed number of integers, i.e., for each cycle T=Mtau of a detecting section pulse T2. An adder 5A and a subtractor 5B deliver the addition value A and the subtraction value B respectively. An interference ratio arithmetic circuit 6 supplies both values A and B and calculates an electric power ratio D<2>/U<2> according to various equations corresponding to the conversion rules of both circuits 3A and 3B to output it.

Title: Vacuum gage
Inventor: ASAMAKI TATSUO
IPC: G01L21/30
Filed: 1989-02-21
Abstract: PURPOSE:To improve measurement accuracy by a method wherein rotating electron current is measured by a cross electromagnetic field type vacuum gage and the ratio of this to ion collector current is calculated. CONSTITUTION:When anode voltage is applied between an anode electrode 21 and a hot cathode filament 11, thermions emit from the filament 11 toward the electrode 21 while electric discharge having high electron density occurs in a space 27 between the electrodes. These electrons are hard to reach the electrode 21 reducing soft X-rays generated when the electrons collide with the electrode 21, while most of ions generated by ionization of gas molecules gather on an ion collector electrode 51 which are detected as ion collector current IC by an ampere meter 53. Since the anode voltage fluctuates, rotating electron current also fluctuates accordingly so that flux density through a sensor coil 41 varies inducing AC current at the coil 41. This induced current is detected by an ampere meter 42. By calculating this induced current, rotating electron current Ir can be calculated. When the pressure inside a gage sphere is assumed to P and the sensitivity coefficient of a vacuum gage is S, pressure P can be expressed by equation P=(1/S)(IC/Ir).

Title: Alloy-type temperature fuse
Inventor: KAWANISHI TOSHIAKI
IPC: H01H37/76
Filed: 1991-02-08
Abstract: PURPOSE:To speed up operation of a temperature fuse made of a low melting point fusible alloy by using a fuse element having a remaining flash formed at the molding time. CONSTITUTION:A fuse element 2 is made of a low melting point fusible alloy bridge over leads 1 and flashes 21 are formed at two points in the circumferential direction of the fuse element 2. When over current caused in an electric circuit runs in the element 2 and the temperature of the element 2 rises, liquefaction proceeds from the center part to both end parts and at the same time liquefaction is carried out along the flashes 21 since the thermal capacity of the flashes 21 is small. Since the molten metal forms a sphere owing to the surface tension of the metal, the metal in the center part is cut. In this way, liquefaction of the fuse element is accelerated by the flashes 21 and thus the fuse operation can become speedy.
