EDUCATIONAL DEVICE FOR STUDYING QUANTUM PHENOMENA Russian patent published in 2007 - IPC G09B23/06 

FIELD: educational devices and aids.

SUBSTANCE: compact and comfortable at use individual device, providing ability of studying the whole complex of tests directed onto learning quantum phenomena in different branches of physics, is described. Device has case with rectangular grooves onto back surface of edge and of side walls intended for cap. Support is disposed inside internal cavity of case. There are diffraction grids, light-emitting diode, rectifier and connecting wires in support. Support is made in form of rectangle with through deepenings; two deepenings are rectangular and one has T-shaped form. Support is attached to edge and side walls of case. One more support, made of shock-conserving material, with dead rectangular opening is disposed between free end of support and other edge side of case. Working rack is disposed between side walls of supports and side wall of case; metal rods and metal bar are fastened in series onto top side of working rack at its end area. Mark is made onto top surface of metal bar. One more bar is fixed at other end area of working rack. Magnets are fixed onto side of bar, which side is turned outside. Device is provided with angular screen; ruler is applied onto external surface of screen's shelf. There is zero count and slot in central part of ruler. U-shaped groove is made in central part of other shelf. Device is provided with support bar, made of material with high friction coefficient; bar is provided with U-shaped groove at side wall; U-shaped groove provides inclined mounting of rack. Radioactivity indicator is placed in support made o shock-conserving material. Device is charged with photos of tracks of charged particles, incandescent lamp, neon lamp, photodiode. All mentioned devices are fixed to their own supports as the light-emitting diode. Support is made in form of basket with step-wised base. One step is provided with magnets which interact with metal bars of working rack. Second step forms a console, which has base to interact with shelf of angular screen within area of U-shaped groove. Edge of console interacts with external surface of bar provided with mark. Side and edge walls of support's basket are provided with flanges which protrude outside bases. Flanges embrace sides of working rack. Electric jacks are made onto top surface of basket and electric symbols of fixed item are applied onto it. Photodiode is placed onto base of basket. One side wall of basket is lower than the other one. Slot in form of dead recess is made at one edge at its internal side; the slot is made in central part of edge. Width of dead recess corresponds to width of working rack. Height of dead recess equals to height of rectangular groove.

EFFECT: improved efficiency of study.
