摘要： A battery-powered, hand-held calculator employs MOS/LSI calculator circuits to perform arithmetic and financial calculations. Data and commands are input to the calculator from a keyboard having a prefix key to double the functions of selected keys. A 15-digit, seven-segment light emitting diode (LED) display serves as the output for the calculator.

摘要： An integral revolution clutch is provided wherein a motor rotates a drive pulley which continuously drives an idler pulley through a belt. A drive shaft is provided with a segment of a circle thereon connectable to the idler pulley by means of the belt. A spring means urges the segment into contact with the belt and a stop means normally prevents contact. When the stop means is deactivated, the segment is drawn between the belt and the pulley, causing the shaft on which the segment is located to make an integral number of revolutions until the stop means is restored. In a similar manner, power can be taken directly from the drive pulley.
摘要翻译：提供一体式旋转离合器，其中电机使连续驱动惰轮的皮带轮旋转。驱动轴设置有可通过皮带连接到惰轮的圆的一段。弹簧装置促使片段与带接触，并且止动装置通常防止接触。当停止装置被停用时，该段被牵引在带和皮带轮之间，使得该段所在的轴成一整数，直到停止装置恢复。以类似的方式，可以直接从驱动滑轮获取动力。

摘要： A battery-powered, hand-held, calculator employs MOS/LSI calculator circuits to perform arithmetic and financial calculations. Data and commands are input to the calculator from a keyboard having shift key to double the functions of selected keys. A 15-digit, seven-segment light emitting diode (LED) display serves as the output for the calculator. The calculator circuits include a read-only memory circuit in which the algorithms for performing the arithmetic and financial calculations are stored; a control and timing circuit for scanning the keyboard, retaining status information about the condition of the calculator or of an algorithm, and generating the next read-only memory address; and an arithmetic and register circuit containing an adder, a group of working registers, a group of data storage registers forming a stack for roll down operation, and a constant storage register. These circuits are interconnected by a multiple line buss system.
