Abstract: An input method including a novel keyboard facilitates entry of Chinese characters into a computer. Character Roots or Radicals are selected in accordance with the first pen-stroke used by Chinese in writing such Root or Radical and those that begin with the same stroke are symbolized on keys in separate selected sections of the keyboard. As a further aid, Roots or Radicals that have the same second pen-stroke are selected and symbolized on specified keys having a secondary identification design or motif. The method includes selecting, in the traditional Chinese order of writing, the first Root to be encoded and, from the keyboard, the key having such Root thereon, the location selection being facilitated as described above, and actuating the key, and continuing to select the second and third Roots in the character and actuating the corresponding keys.

Abstract: A temperature control system for a resistance element which is heated by a power supply connected to it by a switching member, the switching member being controlled by an electronic circuit which is operative to produce alternate ON-cycles and OFF-cycles whose durations are controlled by separate time constants. The durations of these alternate cycles respectively set the higher and lower temperature limits within which the heating element temperature remains. The electronic circuitry further provides a single initial ON-cycle of greater duration which occurs only when the circuit is newly turned ON and operates to bring the resistance element up to operating temperature from ambient temperature, an indicator being provided to glow during each ON-cycle interval. The control system is illustrated for use with a soldering iron which is supportable in a cradle connected with a switch to turn OFF the system when the iron rests in the cradle.
