Title: Deflection coil for image pickup tube
Inventor: OKU KENTAROU
IPC: H01J29/76
Filed: 1981-09-04
Abstract: PURPOSE:To improve the focus characteristic over the entire screen at the dynamic focusing, in a SM type image pickup tube, by bringing the spot shape of the deflected electron beam near to a circle thereby reducing the direction dependability of the resolution. CONSTITUTION:The out of roundness of the corner spot is such that the optimal value is existing for the coil length L and it will become smaller as the distance between the mesh target will become longer. Since the deflection coil is arranged at the outside of the glass tube 13, its diameter Dc must be longer than the average inner diameter D. Consequently the coil length preferable for the out of roundness of the corner spot and the dynamic focus is in the range of 1.05D< L<1.9D while the coil diameter is in the range of 1.0D<Dc<2.0D. When regulating the axial length of the flatwise coil, the spot shape of the electron beam deflected to the circumferential section of the screen is brought near to a circle resulting in the improvement of the dynamic focus characteristic.

Title: Regenerating device for color video signal
Inventor: YAMASHITA NORIYUKI
IPC: G11B5/027
Filed: 1978-11-10
Abstract: PURPOSE: To realize the special regeneration for the color video signal under the state of the color screen by locking the phase of the carrier chrominance signal to the reference signal and at the same time substituting the burst signal with the signal synchronized with the reference signal.  
     CONSTITUTION: At the time of the special reproduction, output signal Sa of system control circuit 70 becomes 0. And with supply of burst flag pulse Pf to terminal 53, the output of inhibit circuit 51 turns to 1 with every burst period. And switch circuit 52 is connected to the side of 1 with every burst period. Accordingly, in that case, carrier chrominace signal Ss containing line sequential signal Sw sent from circuit 42 is drawn out from circuit 52 in place of signal Ss containing burst signal Sb sent from switch circuit 31. Signal Sw is produced from oscillation signal So sent from oscillator 28, and at the same tie signal Ss is locked to signal So. As a result, signal Sw added to signal Ss at circuit 52 functions as the burst signal.

Abstract: PURPOSE:To promote efficiency of heat exchange, effectively utilizing heat exchanging surface relating to convective and radiational heat transfer and also effectively utilizing quantity of heat radiation from the bottom of a combustion tube, by providing a combustion tube having a bottom so that the aperture thereof faces a burner and a reflector facing the bottom of said tube in a combustion chamber. CONSTITUTION:In a heat exchanger employed for a kerosine boiler etc. high temperature combustion gas 3 blown out of a burner 2 flows from an aperture end 6 into a combustion tube 5, runs against the bottom thereof, turns reversely, and smoothly flows backward along the inside surface of the combustion tube 5 to the aperture end 6. Therefore, the combustion tube 5 is heated all over the surface to a red heat to heat effectively a water wall 9 by radiation. Heat radiated from a bottom part 7 of the combustion tube 5, being heated to a red heat all over the surface, is reflected on a water wall 9 by the outside surface of a reflector 8. On the other hand, the combustion gas 3 flowing backward to the aperture end 6 is forcibly convected as shown by an arrow b to heat the whole surface of the water wall 9 including the surface close to a burner connection port 11 by convective heat transfer. Thereafter, the combustion gas 3 flows between the water wall 9 and the outer periphery of the reflector 8, then to a discharge port 12.

Title: Power source circuit
Inventor: YASUDA MAMORU
IPC: H02J1/00
Filed: 1987-06-01
Abstract: PURPOSE:To prevent erroneous operation due to external noise, by providing an abnormality detection circuit having an auxiliary circuit for increasing abnormality detection margin forcibly. CONSTITUTION:Upon interruption of A.C. voltage EAC, photocouplers 52A, 52B turn OFF, and a referential voltage V2 goes to a high level which is determined by voltage division ratio between resistors R1, R2 in an auxiliary circuit 51. Consequently, a predetermined margin is obtained as a differential potential between primary DC voltage EDC and a preset detection level. When a comparison voltage lowers to the referential level V2 at some time after power interruption, an abnormality signal (i) is outputted from a comparison circuit 41. Consequently, one-shot pulse signals (j) are produced for a predetermined time from a mono-stable multi-vibrator 62 and an alarm signal K is outputted from D-type FF64. In such a manner, the referential voltage V2 varies simultaneously with occurrence of abnormality so as to reset the margin quickly to a predetermined level thus providing a reliable initial abnormality detection system.
