Abstract: Methods and apparatus, preferably carried out with the aid of a programmed digital computer for iteratively determining the actual speed of an engine(10) and iteratively updating a fuel rate command signal Vf so as to. govern and correctively remove any errors from the set point speed. Jumps to a program subroutine are triggered by sensing the engine crankshaft 10a to generate a predetermined number Q of pulses during the span of one revolution (where Q is an integer greater than 1). and each pass through the subroutine determines the actual engine speed as an average over the last whole revolution of the crankshaft 10a. There are thus Q iterations per revolution but each iteration signals the speed over one whole revolution. This results in wholly eliminating torsionally induced speed fluctuations, or the like, from the determined speed signal. Each pass through the program subroutine also determines the speed error and updates the fuel rate command signal as a PID function of such error. Because this iterated updating occurs, not at a regularly timed rate, but at intervals which vary inversely with speed, the instructions of the subroutine program can be made very short and simple while nevertheless causing effective automatic tuning adjustments of the integral gain, stability and compensation factors.

Abstract: A process for manufacturing a thin film resistor substrate useful, for example, in fabricating an ink jet printhead, wherein discontinuous strips (20,22) of conductive material are initially patterned on the surface of a resistive layer (16). These strips are formed using a first series of masking and etching steps to define an "X" dimension of a resistive heater element (24). Then, the conductive strips (20,22) and resistive material therebetween are completely masked (26) in preparation for a subsequent, second etching step used to remove the exposed portions of the resistive layer (16) and thereby define a "Y" dimension of the resistive heater element (24). These steps leave smooth contours, good step coverage and high quality bevelled edges (39,40) of the thus defined conductive and resistive layers. These layers are now ready for subsequent passivation layer (42), barrier layer (44) and orifice plate (48) deposition processes to complete a thin film printhead for use in an ink jet printer.

Abstract: In a method for recording and/or reproducing digital'data, such as digital audio signals recorded simultaneously with video signals, dividing sampling data composed of a plurality of bits into higher order bits and lower order bits, constituting error correction coding blocks by only the higher and lower order bits of the sampling data of a plurality of samples respectively, thereby making it possible to easily realize adaptive error checking in the course of the block-by-block error checking in association with, for example, data criticality. 
     A sync word and a block address are affixed to the error correction coding block constituted in that manner. Since one block address is formed using the address data of two or more blocks, a broader address space can be obtained even when the bit number of the address area of each block is few. At least one flag bit(s) are provided in each sync word to use said flag bits in the blocks bearing specified block addresses as edit flags to set the edit flags in association with each edit point of digital signals, thereby facilitating discrimination of the editing points to reduce the rate of data discarding.

Abstract: An apparatus having a rechargeable battery and a battery voltage detector which detects the output voltage of the battery to produce a detection signal when the output voltage falls below a predetermined threshold level. A controller stores a battery capacity value and accumulates the discharge of the battery to produce an accumulated capacity value. The controller also calculates a difference between the stored capacity value and the accumulated capacity value. Using the difference, a display displays the remaining charge value of the battery thereon. If the difference exceeds a predetermined value at a time the controller receives the detection signal, the controller changes the stored capacity value to a new capacity value. Alternatively, the controller may change a rate of accumulating the battery discharge. 
     The apparatus may have a current detector for detecting a current flowing through the battery. The controller may accumulate the battery discharge based on the detected current.
