摘要:
An apparatus for managing power in an electronic device that receives the power from a bus is described. The apparatus comprises a clock enable circuit that disables a clock that generates nominal clock frequencies derived from raw frequencies output by an oscillator upon receiving a first signal. A time-wise independent time reference circuit is coupled to the clock enable circuit. The time-wise independent time reference circuit sends the first signal to the clock enable circuit a first predetermined period of time after receiving a signal to enter into a suspend state.

A toner image is transferred to a heat softened thermoplastic outer layer of a receiving sheet. The toner is transferred from an image member predominantly by heating the receiving sheet to a temperature which both softens the thermoplastic layer and, when the thermoplastic layer contacts the toner, sinters the toner sufficiently to cause toner to adhere both to the thermoplastic layer and to other particles of toner. To prevent blistering, the temperature to which the thermoplastic layer must be raised can be lowered, for example, to 100 degrees C. by also heating the image member to a temperature, above ambient, but less than the temperature that would either do damage to the image member or cause the toner to stick to it.

Imaging apparatus of the kind in which successive image portions of a length of strip material are sequentially imaged and developed, features a development device adapted to provide continuous development periods of equal duration for all image portions, regardless of intermittent operation of said apparatus. One disclosed embodiment features guide means sequentially movable at the strip-feed rate between a first position, constraining all strip portions that are within the development zone in a developing relation, and a second position wherein all such strip portions are released from the developing relation.

A deflection apparatus comprises a deflection amplifier coupled to a deflection waveform modulation circuit such as a diode modulator. A source for generating a modulation signal. The modulation signal comprises a symmetrical periodic AC component having equal first and second portions of a trace period. A feedback amplifier alters the amplitude of a first portion of the trace period relative to a second portion of the trace period to render the AC component asymmetrical. The asymmetrical AC component is coupled to the deflection waveform modulation circuit for deflection waveform modulation.

A method and apparatus for third party agent transaction deferral on a host bus. A host bus transaction request is received from a device, and transaction information related to the transaction request is stored in an out of order queue. An indication is received from the third party agent that the transaction has been deferred, and the stored transaction information is updated to reflect that the transaction has been deferred.

A deflection apparatus comprises a deflection amplifier coupled to a deflection waveform modulation circuit such as a diode modulator. An East-West modulation signal is generated by a digital to analog convertor in accordance with a reference potential coupled thereto. The modulation signal has a DC component for width control, and is coupled to an input of a comparator. The reference potential is also coupled to an input of the comparator to establish a reference bias therefor. The comparator has an output coupled to the deflection waveform modulation circuit to provide the East-West modulation.

A projection television receiver has a cathode ray tube with an electron gun for emitting an electron beam incident on a screen, an electromagnetic deflection yoke and an electromagnetic focusing coil. A horizontal deflection driving circuit is coupled to a horizontal deflection coil and provides deflection current to the horizontal deflection coil for scanning the beam repetitively on the screen. The focusing coil is driven from a current step-down transformer having a primary winding coupled in series with the horizontal deflection coil. A secondary winding of the transformer is coupled to the focusing coil for driving the focusing coil with a horizontal rate parabolic current. A capacitor-resistor circuit is coupled in parallel with the focusing coil and with the secondary winding of the transformer for adjusting a phase relationship of the parabolic current relative to the horizontal deflection current and for adjusting the amplitude of the parabolic current.
