Title: Exposure control system of copying machine
Inventor: ENDOU MAKOTO
IPC: G03G15/04
Filed: 1982-04-28
Abstract: PURPOSE:To obtain a copy image of high quality free of density irregularity, by adjusting a phase and an aperture on the basis of the detected value of a detecting means for control over the amount of exposure. CONSTITUTION:A photodetecting element 19 is arranged closely to the slit of a slit plate 16 to photodetect a part of a projected image reflected by mirrors 6 and 7. The photodetecting element 19 detects transmitted light from an original 1 to detect the image density of the original and detects the amount of exposure prior to image exposure to a photosensitive drum 10. With regard to the density detection of the photodetecting element 19, mirrors 6 and 7 are scanned preliminarily prior to a normal exposure process to scan on the original and during this preliminary scanning operation, the brightness of a lamp 2 and the width of the slit are controlled on the basis of the photodetection amount of light of the photodetector 19 to control the amount of exposure to a photosensitive drum adequately, obtaining an excellent copy of the original.

Abstract: PURPOSE:To prevent easy heating of not only the object to be irradiated but also the ceiling surface and wall surfaces by furnishing a first reflection body, which shuts off infrared beams while reflects visible rays, and a second reflection body which reflects the reflected beam from the first one and emits it. CONSTITUTION:Over a first dichroic mirror 14, a second dichroic mirror 15, for ex. cold mirror of plastics, as the second reflection body with a concave surface formed facing the undersurface whose outer dia. is approx. the same as the dia. of the bore of two oppositely situated frames 2 is placed on ring- shaped silicon rubber 16 fixed to the frames 2 slidably. When a light source 13 is lighted, the first dichroic mirror 14 admits penetration of infrared rays and shuts off reflection while reflects the visible rays. The second dichroic mirror 15, on the other hand, reflects the reflected visible rays and also the visible rays from the light source 13 while admits penetration of the infrared rays and emit them. Thereby the infrared rays are cast concentratedly in the projecting direction of the light flux and in the direction of ceiling on the back of the second dichroic mirror 15. Thus the ceiling surface and the wall surfaces are precluded from heating.

Title: Dustproofing device for optical parts
Inventor: MIYAZAKI TOSHIAKI
IPC: H01S3/08
Filed: 1988-03-29
Abstract: PURPOSE:To protect optical parts against sticking of dust and dirt contained in the ambient atmosphere by utilizing a cylindrical body having double structures to form a toric outflow port and adjusting the quantity of the dry air to be discharged to a specific value. CONSTITUTION:The dry air is supplied to the gap B formed to a circumferential shape through plural pieces of supply ports 6 circumferentially at equal intervals on the outside cylinder 4 having a cylindrical shape so that this dry air leaks from between the open end part of the inside cylinder and the optical parts to fill the inside of the cylindrical body. The dry air forms the flow heading toward the outside over the entire area of the cylindrical body 5 when the flow rate of the dry air is so adjusted that the Reynolds number attains 200<=Re<=500. The stagnation of very slight fine powder is then merely generated in the central part at the outlet of the inside cylinder 5 and the infiltration thereof into the deep inside part is obviated. Sticking of the dust in the ambient atmosphere to the optical parts is thereby averted and the degradation in output and the deterioration of the optical parts are prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce both a control voltage and a leakage current at the same time in a field-emissive element. SOLUTION: In this field-emission element, a gate electrode 50 is formed on a resistant layer 20, which is an emitter electrode, interposing a first insulating membrane 30 and a second insulating memberane 40. The structure such that the gate electrode 50 and both insulating membranes are extended as far as the side face of a projection 25 of the emitter, and a tip of the projection 25 and an opening 55 of the gate electrode 50 face each other, interposing an aperture having the thickness of the first insulating memberane 30. Electric field applied on the projection 25 is affected, only by the thickness of the first insulating membrane 30, therefore a control voltage can be reduced by forming the first insulating membrane 30 thin. Also the second insulating membrane 40 is affected only by the distance from the gate electrode 50 to the resistance layer 20. Therefore, both the control voltage and a leakage current can be reduced at the sometime, by forming the first insulating membrane 30 thinly and the second insulating membrane 40 thickly.

Abstract: PROBLEM TO BE SOLVED: To decide the depression range of a finger and to sample an accurate fingerprint by mounting a matrix switch plate on a fingerprint impression base and discriminating the depression range of the finger, and extracting and processing the picked-up image in the depression range. SOLUTION: The matrix switch plate 2 which makes a contact by depression is mounted on the fingerprint impression base 1 and a coordinate detecting circuit 3 detects coordinates in the depression range from the area where the contact of the matrix switch plate 2 is made.
