Title: Power supply circuit of television receiver
Inventor: AKIYAMA HIROSHI
IPC: H04N3/18
Filed: 1983-03-11
Abstract: PURPOSE:To attain an inexpensive circuit by rectifying a voltage at the secondary side of a flyback transformer, and supplying the oscillating output of a horizontal oscillating circuit by the resulted rectified voltage to a horizontal driving transistor (TR) via an isolation transformer, and separating the circuit into a charging part and a non-charging part by both the said transformers. CONSTITUTION:A DC voltage is outputted from a stabilizing circuit 11 to the charging part 25, and a bias is applied to a base to the horizontal drive TR6 by a start circuit 29, and the TR6 is made conductive. Then, a charging capacitor 31 is charged. A pulse voltage is generated in a secondary winding 8b of a driving transformer 8 in this case, a horizontal output TR16 is turned on and off, thereby causing a pulse voltage in the primary winding of the flyback transformer 12. A pulse voltage generated in the ternary winding 12c is rectified in this case to activate the horizontal oscillating circuit 5. The oscillated output is applied to the TR6 via the isolation transformer 33 to turn on and off the TR6 and to bring the TR16 into the steady state. Since the rectified voltage being a tap voltage at the primary side of the transformer 12 is low voltage in steady state, a low dielectric strength TR is enough for the TR6.

Abstract: PROBLEM TO BE SOLVED: To provide a driving equipment which, regardless of the stop position of a rotor, can always start up accurately and rapidly a sensorless and commutatorless DC motor wherein induced voltage signals from armature windings are processed by a rotor position signal generating circuit and then a rotor position signal is obtained and then driving current is supplied to the armature windings of respective phases U, V, W, being reversed every other one cycle, six times, and thereby the rotor is driven. SOLUTION: At the time of start-up, a start-up signal generating circuit 17 generates a start-up signal which reverses a rotor every other one cycle, six times, and then fixes the rotor to a stop phase for a specified period of time and then rotates the rotor in the forward direction. The signal is supplied to an armature winding driving circuit 10. When the rotational speed of the rotor increases enough to induce sufficient voltage in armature windings 6, a switching circuit 13 is switched and normal operation is started by a positional signal from a rotor position signal generating circuit 11.

Abstract: PURPOSE:To prevent a movable iron piece from being removed by providing an engaging part to be engaged with cutouts of both sides of the piece at either a supporting plate or a coming-off preventive plate. CONSTITUTION:A movable iron piece 30 is unremovably attached to a plate part 23 with a pair of engaging pieces 23a formed at the part 23 and a through hole 43 of a coming-off preventive plate 40 secured to the part 23.

Abstract: PURPOSE:To expand a saturated output of the 4-plate solid-state image pickup device while keeping a proportional relation between a level of an object image of each color and a corresponding image pickup element output level. CONSTITUTION:An object image is formed by an objective lens 30, the image is decomposed into red, green and blue images by a color separation prism 31 and the green image is decomposed into two images by a half mirror 31a.
