Title: Reciprocating recording device
Inventor: NAGATO KAZUSHI
IPC: B41J19/18
Filed: 1988-05-27
Abstract: PURPOSE:To obtain a thermal transfer type reciprocating recording device, in which a picture image is not deteriorated by the stretching effect of ink at the time of not only forward recording but also reverse recording, by providing a means controlling the pulse width of conduction pulses so that the pulse width at the time of reverse recording is made shorter than that at the time of forward recording. CONSTITUTION:A recording-direction signal 12 displaying the direction of current recording is transmitted to a heat accumulation control section 10, and the selection method of conduction pulses in a conduction pulse selective section 13 and a voltage control method in a recording voltage control section 14 are varied by the recording- direction signal 12. A data in arbitrary pulse width is selected from conduction pattern data by the state of array and direction of recording of data in an aimed dot and eight dots in the periphery of the picture point in a ROM 36 for selecting conduction pulses, and output as a code data 15 displaying the pulse width of conduction pulses recording the aimed dot. That is, recording is conducted at conduction pulses having approximately the same pulse width as a recording period on forward recording, and recording is performed at conduction pulses having the pulse width of the half of the recording period on reverse recording. Accordingly, conduction pulse width is controlled to the stretching of ink in reverse recording.

Title: Switch circuit
Inventor: HAYASHI YOSHIHIKO
IPC: H03K17/00
Filed: 1981-08-24
Abstract: PURPOSE:To reduce conduction resistance of the mainswitch by inserting the main switch into the negative feedback loop of an amplifier circuit controlling make and break by external signals. CONSTITUTION:When an external signal CONT is made to a high level a main switch 1 and a controlling switch 2 are turned on through a buffer 6. Consequently, DC amplifiers 4, 5 form a negative feedback loop, and terminals A, B become in conduction. The resistance between A and B at this time approximates to a value obtained by dividing conduction resistance of the main switch 1 by voltage gain A2 of the amplifier 5. When an external signal CONT is made to a low level, switches 1, 2 are turned off, and a controlling switch 3 is turned on and consequently, the section between A and B becomes open state. The resistance between A and B at this time approximates to the resistance of the main switch 1 when it is open.
