A lite-counting apparatus counts lites in a longitudinal array. During a traversal by the apparatus of a peripheral portion of the array, a beam of radiation is passed from at least one source to at least one detector. Based upon changes in the relative path taken by the beam, the articles may be counted.

A counter has an electrically erasable and programmable read-only memory (EEPROM), a write circuit, and a read circuit. The EEPROM, which can be rewritten at least V times, is divided into count areas M.sub.O, . . . , M.sub.N each capable of storing count values from zero to V, and a number area for storing a number K from zero to N identifying the count area currently in use. The write circuit uses the count areas M.sub.O, . . . , M.sub.N in succession to store counts as high as N.times.V. The ...

When a cylinder is urged to displace a piston rod, and a pulse signal is inputted into a counter from an encoder, then the number of pulses of the pulse signal is counted by a counting section. A time-measuring section starts measurement for the elapsed time upon the start of operation of the cylinder. When the pulse signal is inputted, the elapsed time is reset. When the displacement of the piston rod is stopped, the pulse signal is not inputted. The elapsed time is increased to make coincidenc...

A high-speed counter using radix-N Signed-Digit redundancy adders, an initial value generator and an interim value generator for each digit. The initial value is selected based upon a desired count. The transfer digit and interim value for each digit are generated to eliminate a carry propagation from a lower digit position. The high-speed counter reaches a desired count with a certain delay time regardless of the starting count value.

A counter employs a barrel for rotatably mounting high order counter wheels and a shaft integrally extending from the barrel for mounting the lowest order counter wheel. The barrel forms a groove in which the transfer pinion assembly is located. The walls of the groove are engageable by the pinion assembly to limit skewing of the pinion assembly components. The transfer pinions are configured to prevent axial jamming displacement against the counter wheels. The lowest order wheel is snapped onto...

A counter employs a barrel for rotatably mounting high order counter wheels and a shaft integrally extending from the barrel for mounting the lowest order counter wheel. The barrel forms a groove in which the transfer pinion assembly is located. The walls of the groove are engageable by the pinion assembly to limit skewing of the pinion assembly components. The lowest order wheel is snapped onto the shaft and secured in position by means of a semi-flexible mounting hub and cooperative shaft dete...

A counter has a memory which stores at least three continuous numerical values and a controller which rewrites a lowest numerical value to a numerical value obtained by adding 1 to a largest numerical value within said continuous numerical values stored in the memory and discriminates whether or not said numerical values stored in the memory are continuous to judge a count error. When said numerical values stored in the memory are not continuous, the noncontinuous numerical value is corrected by...

A counter particularly useful for a program counter comprising a plurality of logic units representative of digits of information data being stored in the counter, each logic unit including a flip-flop circuit indicative of the value of each digit, an exclusive OR circuit connected with the input of the flip-flop circuit and an OR circuit connected with an input of the exclusive OR circuit, the output of the flip-flop circuit being connected to another input of the exclusive OR circuit. A contro...

A zero-restting type of counter comprising a plural number of digit wheels supported on the same shaft and having digit-shift pins, driven gears arranged between individual pairs of said digit wheels, intermittent transmission mechanisms for coupling the individual digit wheels with the corresponding driven gears, digit-shift pins and pinions engaged with said driven gears. Said counter is adapted in such a manner that rotation of said driven gears caused by rotation of said pinions is transmitt...

A counter consists of, to simplify the control of component parts and to improve the productivity, a first frame unit comprising a plurality of digit wheels, a driving gear for a digit wheel of a lower most order, an order shifting-up means and a zero-resetting means, a second frame unit being capable to be snap fitted on the first frame unit and comprising a driving means to be coupled with the driving gear when attached to the first frame unit, and a cover frame unit being capable to be snap f...
