Abstract: PURPOSE:To efficiently recover silver as easily separable silver sulfide with a compact device with high current efficiency by making the voltage to be impressed between both electrodes higher than the sulfide ion generating voltage, and electrolyzing a photographic processing soln. CONSTITUTION:An anode 1 and a cathode 2 are arranged in an electrolytic cell 3 in opposition to each other, and a silver-contg. soln. consisting of a waste photographic processing soln. is introduced from an inlet 6 and allowed to overflow from an outlet 7. An electrolytic current is applied between both electrodes 1 and 2 to electrolyze the silver-contg. soln.

Abstract: PURPOSE:To obtain the process for production of the doorplate made of a noble metal composite plate which does not expose the base metal at the end face even of the doorplate consisting of a composite material consisting of the-base metal thinly lined with a noble metal by molding the composite end face on the circumference where the base metal after cutting is exposed and coating this end face with the noble metal. CONSTITUTION:An Au plate 1 and Cu plate 2 respectively having prescribed thicknesses and longitudinal and transverse lengths are laminated and are joined at hot at a prescribed temp. for prescribed time under pressurizing force in an atmosphere N2+H2 of specified conditions. The laminate is thereafter finished by rolling to a prescribed thickness and is cut to the prescribed longitudinal and transverse lengths to form the noble metal composite material. The composite end face of the circumference of such material is then subjected to rounding in three stages by press forming to form the noble metal composite doorplate 5. The base metal of the end face is coated with the noble metal which is the front surface layer by molding the composite end face of the circumference in such a manner. The impairment of the beauty by the oxidation and discoloration of the base metal at the end face is thus prevented in spite of long-term use. The molding of the composite end face of the circumference is preferably executed plural times to gradually cover the end face with the noble metal.

Abstract: PURPOSE:To sufficiently make a switchover from lighting a miniature electric bulb to entire lighting-up only at one time opening and closing operation by having a first switching means for switching a lighting condition over to N-step conditions through the operation of operating members, and a second switching means for switching a lighting condition from the N-step conditions to N-1 step ones excluding a light-extinguished one in operative association with opening and closing a power source circuit for a floodlight. CONSTITUTION:When a pull string 26 or the like provided to a lighting system is operated, a first switching means is actuated to switch a lighting condition over to such N-step conditions including a light-extinguished condition as, for example, making sequential switchovers from entire lighting-up to light-adjusted lighting, thence to lighting a miniature electric bulb and extinguishing the lighting system, and back to the entire lighting-up. The lighting system may be extinguished accordingly even through the operation of the pull string or the like. When a power source circuit 2 on the other hand is opened and closed through the operation of a wall switch 9 or the like, a second switching means is actuated to switch a lighting condition over to such N-1 step conditions excluding the light-extinguished condition as making sequential switchovers from entire lighting-up to light-adjusted lighting, thence to lighting the miniature electric bulb and back to the entire lighting-up. It may consequently require such simple operations as lighting the miniature electric bulb extinguishing the lighting system (opening the wall switch) and entirely lighting the lighting system to make a switchover from lighting the miniature electric bulb to the entire lighting-up by use of the ordinary wall switch 9.

Abstract: PURPOSE:To prevent occurrence of shadow of electrode supporting member y increasing the deflection angle of electron beam when scanning in a strip scanning area near to the electrode supporting member. CONSTITUTION:When varying the scanning position sequentially in the arrow direction C, an electron beam is initially projected at the arrow position 100 of a back face electrode 10b while to scan by specific width in perpendicular direction against the plane of drawing. Then the electron beam is deflected in the arrow direction 101 to scan again in perpendicular direction against the plane of drawing. When scanning the strip scanning area near the first electrode supporting member 3, the electron beam at the position of the backface electrode 10a is employed to project the electron beam from the position shown by the arrow 102 where the vertical deflection angle theta2 will satisfy the relation theta2>theta1, while to scan by predetermined width in perpendicular direction against the plane of drawing. Since the position shown by the arrow 104 is near to the first electrode member 3, the electron beam at the position of the backface electrode 10d is employed to project the electron beam while satisfying the deflection angle in the arrow direction theta1<theta3.
