Patent JP-H03259310-A (JP)
Title: Voltage comparator
Inventor: ISHIKAWA HITOSHI
IPC: G01R19/165
Filed: 1990-03-09
Abstract: PURPOSE:To obtain a voltage comparator which generates a hysteresis voltage by a small number of elements by using a current from the multi-main electrode on one side of a pair of transistors(TR) comprising its own differential amplifier. CONSTITUTION:Voltage drop I6XR16 occurs between the base and collector of the TR 10 by permitting a current I6 to flow on the TR 2A of multicollector when an input voltage VIN is low. In such a case, the base potential VB1 of the TR 1 is shown in equation I. When the voltage VIN is increased, and the TR 1 is turned on, and the TR 2A is turned off, no collector currents I6, I7 of the TR 2A flow, and the base potential of the TR 10 is decreased by I6XR16, and the base potential VB1' of the TR 1 is shown in equation II. Also, when the TR 1 is turned on, the TR 21 is also turned on, and the TR 24 is turned off, therefore, difference between the voltage VB1 and VB1' goes to the hysteresis voltage DELTAV=I6XR16 (equation I-II) of the voltage comparator, thereby hysteresis characteristic can be attached on input/output relation.

Abstract: PROBLEM TO BE SOLVED: To automatically produce the signals for the kinds of supply voltages inputted into the electronic circuit corresponding to many kinds of power voltages while suppressing the increase of power consumption. SOLUTION: A supply voltage sensing circuit 16 judges the magnitude of the power voltage, according to the threshold voltage based on the reference voltage obtained by a reference voltage generating circuit 12, and a sensation result latch circuit 17 preserves that judgment result.

Abstract: PURPOSE:To improve the image quality by inhibiting smoothing processing from a page at which multi-value processing data are detected so as to reduce a state that a smooth color change or gray change or the like is not expressed in an image output. CONSTITUTION:When an interpreter 211 detects multi-value processing data, a CPU 219 makes a request to invalidate smoothing processing to an engine 217, which controls a smoothing processing section 217a and executes printing without using smoothing processing. In addition to the operation above, the CPU 219 calculates a ratio of the multi-value processing data shared in data of one page and makes a request of invalidating the smoothing processing to the engine 217 only when the ratio of the multi-value processing data exceeds an invalid operation level after the data of one page are expanded in a frame buffer 215. Then the engine 217 according to the request controls the smoothing processing section 217a and executes printing without using the smoothing processing.
