Title: Pulse-current driver for magnetic bubble
Inventor: TAKAHASHI TSUNESUKE
IPC: G11C19/08
Filed: 1978-08-24
Abstract: PURPOSE: To prevent a magnetic-bubble functional element from fusing without losing its operation by a simple constitution by controlling the driving current for the magnetic bubble functional element by using a diode array, capacitor, resistance, clamping diode, etc.  
     CONSTITUTION: In a rise of a driving pulse from current-pulse generating source 7, great part of the driving pulse current flows through capacitor 6 of small impedance to drive magnetic bubble functional element 1 via diode array 3. Then, the impedance of capacitor 6 increases to flow the driving current through resistance 8 and, in consequence, a current flowing through element 1 is controlled, so that element 1 will be prevented from fusing. In a fall of a pulse from generating source 7, capacitor 6 is rapidly discharged by bias resistance 4 connected to array 3 and high- potential clamping diode 5 connected in parallel to resistance 4 to drive element 1 excellently and generating source 7 generates a pulse with its width controlled, so that the fusing of the functional element can be prevented without influence of a temperature.

Abstract: PURPOSE:To ease the manufacturing accuracy of an optical scanning system by passing the luminous flux which is lost of planeness by incidence in a direction diagonal to a light deflector through one or plural pieces of prisms having mutually equal vertical angles thereby recovering the planeness after passage through the prisms. CONSTITUTION:If the reflection surface 15 of a polygon 14 is maintained always in a vertical direction, and a luminous flux 16 is projected at an incident angle +omega to the polygon 14, the reflected luminous flux passes through a single prism 17 or passes through prisms 18, 19 having the same vertical angle DELTA, by which the luminous flux is refracted; thereafter the refracted flux scans a photoelectric drum in a horizontal direction. Here the luminous flux which is lost of planeness by incidence in the direction diagonal to the polygon 14 is restored of the planeness after passage through the prism 17 or 18, 19 and permits expansion at a prescribed magnification ratio while maintaining the planeness, whereby the errors by the face inclination of the polygon are decreased.

Abstract: PURPOSE:To achieve a printing on a plain paper while enabling a high-speed printing and a color printing with a high resolution by laminating a conductor layer, a semiconductor layer and an electrifying layer on one main surface of an electrically insulating heat conductor layer sequentially while a hot melting ink layer is laminated on the other main surface thereof. CONSTITUTION:An electrifying transfer recording medium is piled on a body 206 to be transferred, an electrode stylus 207 is pressed on an electrifying layer 204 and then, a voltage is applied between the electrode stylus and a conductor layer 202 from a power source 208. Consequently, current flows through the electrifying layer to heat a part of a semiconductor layer 203. The resulting heat melts a hot melting ink layer 211 right below a heat conductor layer 201 therethrough to be attached to a body 206 to be printed. Thereafter, when the electrifying transfer recording medium is separated from the body being printed, a part 212 of the hot melting ink is left to enable a printing. In this case, the attaching of debris of the semiconductor layer to the body to be printed due to electrification is prevented by the heat conductor layer 201 thereby producing a clear dot shape and color.
