Abstract: PURPOSE:To prevent toner from sticking on a no-image area without any limitation of the position of an original and copy paper side by bringing an eraser under the control of an eraser control means so that necessary photodetecting elements in the photodetecting element group of a reflection density detecting means illuminate according to an original position. CONSTITUTION:The eraser 41 turns on corresponding to respective picture elements of the photodetecting element group 71 of the reflection density detector 53 and a set of picture elements with a reflection factor lower than a predetermined value, i.e. no-image area is obtained on the basis of image density stored in a RAM56. Then, LEDs of the eraser 41 corresponding to the no-image area are turned on according to copy magnification to prevent toner from sticking in the no-image area. Further, picture elements on the border between the no-image area and an image area are lower in reflection factor than a white ground original when an original pressure plate 21 has a specular surface, etc., and when a development copy is taken in this state, the toner sticks on the contour of an original. For the purpose, LEDs of the eraser 41 corresponding to the picture elements on said border are turned on to prevent the sticking of the toner.

Abstract: PURPOSE:To obtain the MIS type blue color light emitting element comprising ZnSe with high efficiency at low voltage by a method wherein the first ZnSe layer and the second N type ZnSe layer with the carrier concentration lower than that of the first ZnSe layer are laminated on a substrate. CONSTITUTION:The first N type ZnSe layer 12 with carrier concentration of 5X10<17>/cm<3> and the second N type ZnSe layer 13 with carrier concentration of 5X10<16>/cm<3> are laminated on N type GaAs substrate 11 by means of the molecular beam epitaxial process while an insulating layer 14 comprising SiO2 and a metallic layer 15 are formed on the layer 13. The inlet emitted from the second ZnSe layer 13 will not be absorbed into the substrate 11 since the second ZnSe layer 13 with high resistance emitting blue color light is formed very thin with thickness of 5,000Angstrom  and the first ZnSe layer 12 with thickness of 14mum and the same band gap as that of the second layer 13 is arranged between the substrate 11 and the second layer 13. The resistance of the overall elements may be minimized since the resistance of the first ZnSe layer 12 is much lower than that of the second ZnSe layer 13.

Filed: 1986-05-30
Abstract: PURPOSE:To make it possible to locate a submarine boat simply and at the real time, by measuring the thrust and its direction of the screw from the output of plural strain gauges, and finding a displacement from a standard point together with the output of an ultrasonic measuring device. CONSTITUTION:When an operation signal is entered to the screw 2 of a submarine boat, and a thrust is produced by its propeller 2a, the thrust and its direction are detected by plural strain gauges 9 arranged at a trapezoid 4, and from the inertia force and the fluid resistance of the boat measured preliminarily, the acceleration and consequently the speed are found. On the other hand, by finding the speed or measuring the time by an ultrasonic measuring device, from the frequency variations when the ultrasonic waves discharged from the boat come back through a transponder, an error from the tide is produced, which is added to the speed found by the strain gauges 9, to find the displacement from the standard point. In such a way, the real time locating is acquired in a simple and a low cost structure, even in a small submarine boat, and the position control can be carried out.
