Filed: 1987-04-09
Abstract: PURPOSE:To increase an operating efficiency, by a method wherein the title controller is provided with a first and a second counters and the trouble of a photoelectric transducing circuit is decided in accordance with the output numbers of both counters. CONSTITUTION:The controller of a thyristor transducer is constituted of a micro-computer 12, a first input circuit 13 for reading forward voltage signals 1a-Na, a second input circuit 14 for reading a gate pulse command (d), a RAM circuit 15, a ROM circuit 16, an output circuit 17 and a CPU circuit 18. Respective forward voltage signals 1a-Na are compared with forward voltage neglecting signals 1e-Ne from a micro-computer 11 in an AND circuit 19-1-N before inputting them into an OR circuit 17. By this operation, photoelectric transducing circuits 8-1-N neglect the existing forward voltage signals and preclude the inputting of the forward voltage signals into the OR circuit 9. As a result, a forward voltage OR signal (b) becomes zero and the gate pulse command (d) is stopped.

Title: Print wire driving gear for dot printer
Inventor: ITOU KIYOSHI
IPC: B41J2/285
Filed: 1978-07-14
Abstract: PURPOSE:A print wire driving gear, which performs a stable and high-speed operation of a movable magnetic material by fixing one end of a plate-shaped recovery spring attached to the movable magnetic material and applying the other end with a simple support structure. CONSTITUTION:When an exciting coil 4 set with an aperture 7 is electrified, a movable material 2, held with a recovery spring 3', is drawn toward a fixed magnetic material 1c with a center hole. When the exciting coil 4 is diselectrified, it resumes the initial position by the recovery spring 3'. In order to perform the parallel movement of the movable magnetic material during this one cycle operation, the spring constant of the recovery spring 3' at the simple support part 3a must be equal to the spring constant of the same at the fixed end 3b in relation to the movable magnetic material 2. Thus structured, no chattering occures if the distance between the center of the movable magnetic material and the tip end of the spring on the simple support side is changed due to the flexion of the recovery spring, and the movement locus of the movable magnetic material is made stable.
