摘要： A simplified and compact typing machine to be incorporated in an electronic calculator has a type wheel for presenting different numerals upon rotation. The type wheel is moved along a line of digits, i.e., laterally and in the generally horizontal direction, for typing successive numerals and the typing is performed when a hammer head is swung, or the type wheel is rotated, by the movement in one direction of an acting rod of an electromagnetic relay. The same relay acting rod also laterally moves the type wheel in the direction of the line of digits, on its return motion, by a distance corresponding to the space of one digit.

摘要： A frequency band selection switch and variable resistor assembly for one channel of a television tuner in which tuning is performed by varying a tuning voltage. A tuning shaft is connected to the slider of the variable resistor through a harmonic drive reduction gear assembly. A tuning scale is connected to the slider through a bored tuning scale shaft through which the tuning shaft coaxially extends. A bored switch shaft through which both the tuning and tuning scale shafts coaxially extend carries a movable contact of the band selection switch and a frequency band indicator. An assembly support member has a graduated dial associated with both the tuning scale and the frequency band indicator in a unitary manner.

摘要： A printing apparatus for an electronic calculator or the like comprises a first type wheel formed with mathematical operator symbols which is fixed to a spline shaft and a second type wheel formed with digits which is slidably mounted on the spline shaft for integral rotation. A stepping motor rotates the spline shaft for character selection. A carriage is connected to the second type wheel and is movable by a cable wound around drive and take-up spools to move the second type wheel along the spline shaft for serial feed. A single electrical solenoid actuates a printing hammer for printing and subsequently actuates a ratchet and pawl mechanism to serially feed the second type wheel by one character position in one reciprocation of the solenoid plunger. A linkage initially connects the plunger to a first printing hammer associated with the first type wheel to print the mathematical operator and subsequently to a second printing hammer associated with the second type wheel to serially print digits from least significant to most significant.
