Title: Image forming device
Inventor: OKAMOTO YUKIO
IPC: G03G15/08
Filed: 1987-12-04
Abstract: PURPOSE:To make toner concentration accurate and to always keep it constant by detecting toner concentration, which is a reference, writing the detected value in a nonvolatile memory and controlling toner concentration detected at the time of forming an image so that it is equal to the reference value. CONSTITUTION:A voltage in accordance with the toner concentration of the developer of the reference concentration measured in an inductance sensor 34 is converted into a digital value in an A/D converter 36 and written in the nonvolatile memory 37, then an initial setting action is completed. During a copying process, the toner concentration gradually lowers. Now, the detection output from the sensor 34 is impressed on one terminal of a comparator and the detection voltage of the sensor at the time of getting the reference toner concentration written in the memory 37 is impressed on the other terminal thereof, then the voltage in accordance with difference between both of them is outputted. Based on the output, a toner replenishment indication means 40 instructs whether the replenishment of toner is executed or not to a toner replenishing means 35. The replenishment of the toner is performed by the means 35 until the toner concentration coincides with the reference value according to the above-mentioned instruction.

When putty 15 is placed on a plate 11, which is made of a polyethylene resin and formed in a discoidal shape and in which a large number of through-holes 13 are bored to a periphery, and pushed against the head of the screw 3, putty 15 enters a clearance formed by the head of the screw 3 and a hole 6 by pushing force, and residual putty 15 is transferred to the peripheral section side. Putty 15 is formed in a filmy shape and protruded to the outside as spherical lumps 16 from the through-holes 13 at a stage when the plate 11 is abutted against the steel plate 5. The inside of the clearance 4 is filled with adhesives, and the plate body 11 is removed after the curing of adhesives.  Since a clearance between the steel plate 5 and the screw 3 is sealed with a small quantity of putty 15 in a filmy shape, the waste of putty 15 is prevented, and the leakage of infected adhesives can also be obviated. The removal works of the residual section of putty 15 are also facilitated.

Atomic hydrogen is adsorbed to a previously normalized silicon surface, changed into silane gas (SiH4) at 600 deg.C or more, and discharged to a shape that atomic hydrogen takes one silicon, thus etching the silicon substrate in an anisotropic manner. The mask material is not corroded at a low temperature of approximately 600 deg.C, thus allowing the selective etching of silicon. The etching anisotropy, etching depth and the quantity of side etching, of the silicon substrate are determined by the speed of the atomic hydrogen flow.
