Abstract: An impact-type printing device includes a printer for printing characters with a plurality of impression pressures including a high impression pressure sufficient for printing on all of the sheets of a set of copy sheets. The device also include a keyboard having a key for selecting one of the plurality of impression pressures when the device operates in a normal operation mode. The device further includes a switch for switching the device between the normal operation mode and a copy mode of operation. In the normal mode the printer is capable of printing in any of the plurality of impression pressures selected by the operator at the keyboard. In the copy mode the printer prints only with a high pressure, sufficient for printing on all of the sheets of the set of copy sheets. The device also erases a previously printed character when in the normal mode and overstrikes the previously printed character in the copy mode.

Abstract: A hybrid element for phase shifting an input signal and providing a phase shifted output signal includes conductive plates which are capacitive coupled together. The hybrid element includes four terminals: an input terminal for receiving an input signal, an isolation terminal capacitive coupled with the input terminal and for providing an output signal, a through terminal connected directly with the input terminal, and a coupling terminal capacitive coupled with the input terminal. A distributed constant line and an FET are connected in pair with the through and coupling terminals, respectively, the other end of the distributed constant line being connected with earth. When the FET is turned on or off, the amount of phase shift in the phase shifter is controlled. Since the FET and distributed constant line are connected together in parallel, the amount of phase shift can be adjusted easily by turning the FET on or off.

Abstract: A printing apparatus includes a print wheel having a vertical lien character, a minus symbol character, and an underline symbol character. A first control moves a carriage on which the print wheel is mounted at one of two pitches and a second control advances a printing paper for receiving printing at one of two pitches in a direction generally perpendicular to the direction of movement of the carriage. Respective keys select the vertical line character and underline character for printing and the printing and paper-advancing pitches. One key signals repeat actuation of either the key selecting the vertical line character or the underline character and a memory stores actuation of the key for selecting the vertical line character. Printing of a vertical line character and advancement of paper is achieved by a control in response to actuation of the repeat signaling key, if the memory stores actuation of the vertical character key.

Abstract: A printer has a memory containing print information on a plurality of characters, grouped by a print pressure of the character, and a control unit for controlling the print pressure in accordance with the print information stored in the memory. The memory stores the print information for each print pressure group in ascending order. The duration of the impact pulse is determined once the character's code is found in the list of characters stored in order of lowest to highest impact energy, based on character size.
