Title: Ceramic heater for ignition
Inventor: SUZUKI YASUHIKO
IPC: F23Q7/22
Filed: 1989-03-23
Abstract: PURPOSE:To enable lowering the operative surface temperature set for ignition so as to achieve an improvement in the durability by enclosing a heater assembly in a sheath in such a manner as to provide some space therebetween and by forming a plurality of openings in the sheath. CONSTITUTION:With rise of the temperature at the surface of a heater assembly 10, the temperature of a sheath 22 which encloses the heater assembly 10 also rises by its heating. Between the sheath 22 and the heater assembly 10 is provided a space which permits entry of fuel gas mixed with air. The mixture of fuel gas and air which enters this space slows down in the rate of passage and, during the passage, is exposed to heating by the heater assembly 10 and the sheath 22. Therefore, the time for which the fuel gas mixture is heated is lengthened and its temperature rises sufficiently high for the ignition. As a result, the fuel gas can be easily ignited. Thus the lengthening of the time for heating the fuel gas permits the heating to be moderated in temperature and the temperature of a ceramic heater can be set at a lower point.

Title: Digital phase lock loop stabilizing circuit
Inventor: WARUTAA HAINRITSUHI DENMAA
IPC: H04N11/04
Filed: 1987-03-27
Abstract: As used in a digital television receiver the invention includes a first phase locked loop which develops a sampling clock signal (CK) that is locked to the horizontal line synchronizing signals components of a composite video signal. A second digital phase locked loop is clocked by the sampling clock signal and develops a digital signal that is phase locked to the color burst signal. This signal is used as a regenerated color subcarrier signal to synchronously demodulate the chrominance components of the composite video signal into I and Q color difference signals. To compensate for frequency instabilities in the regenerated subcarrier signal caused by frequency instabilities in the line-locked clock signal, a third digital phase locked loop (300) develops an oscillatory signal (from oscillator 302) which is phase locked to a reference signal generated by a crystal controlled oscillator (310). A control signal (C') from the third phase locked loop is applied to circuitry (329, 338) which develops a control signal (C'') that is independent of the crystal frequency. This control signal is applied to modifying means (328) in the second phase locked loop to substantially compensate for frequency instabilities related to the clock signal. Since the control signal applied to the second phase locked loop is independent of the frequency of the control, there is no need for manual adjustment of the crystal oscillator.
