Title: Counting rate meter device
Inventor: YANAGI TOSHIO
IPC: G01T1/17
Filed: 1992-06-09
Abstract: PURPOSE:To prevent eventual varying of the input value from affecting the output value and provide measurability with high resolution by measuring the pulse signal generating intervals, dividing the unitary time with this interval value, and determining the counting rate. CONSTITUTION:Radiations 13 emitted by a radiation (gamma-rays) source 11 are attenuated by a piping to be measured 21, scale 22, and fluid 23 and reach a radiations sensor (scintillation count type). When bombarded with the radiations, the scintillator (cesium iodide) 31 emits light corresponding to the number of bombarding particles. A photo-sensor (photo-diode) 32 converts these photo-pulses into electric pulses. A counting means 41 of a counting rate meter device 100a as a radiation intensity measuring part measures the intervals Ti of pulse signals emitted from the sensor 34, and a mean calculating means 42 calculates the mean T of the pulse intervals Ti in N pieces. In advance a reference time Ts is given to a setting means 43, and a counting rate calculating means 44 calculates the counting rate by computing Ts/T.

Abstract: PROBLEM TO BE SOLVED: To prevent image inferiority such as character drop out from being caused because of shortage of applying amount of a lubricant onto an image carrier in a lubricant applying device in which the solid lubricant is applied to the image carrier by rotating a fur brush while being in contact with both the solid lubricant and the image carrier, by forming a surface thereof flat and touch area between the fur brush when the solid lubricant is newly used and forming the solid lubricant small till the solid lubricant surface is scraped off to some degree after starting of use. SOLUTION: An upper layer part 1a of the solid lubricant is formed so as to be scraped easier than at a lower layer part 1b. By using the same material such as zinc stearate, different molding conditions are applied to the upper layer part and the lower layer part. Otherwise different materials with different scraping easiness are used for the upper layer part and the lower layer part of the solid lubricant 1. For example, zinc stearate for the upper layer part and ethylene bisstearylamide for the lower layer part are used. Otherwise the same effect can be expected by previously making the fur brush contain the prescribed amount of the solid lubricant before starting real applying of the solid lubricant to the image carrier.
