Title: Impact printer head
Inventor: YOSHIDA HITOSHI
IPC: B41J2/295
Filed: 1990-05-17
Abstract: PURPOSE:To reduce a printing noise, to improve a printing quality and to easily line-feed a printing head by mounting a piezoelectric element in a housing for storing the head, and substantially simultaneously applying a vibration waveform having a reverse phase from the element to the vibration waveform of the housing upon printing. CONSTITUTION:When a coil 6 is energized, a magnetic attraction force is operated at an armature 5 to move it in a direction (a), and the end of a printing wire 3 prints through an ink ribbon. After printing, the armature 5 is returned in a direction (b) by an armature returning spring 8 to collide with a back stopper 9 and returned to a stopping position. The stopper 9 and a retaining member 12 are vibrated by the collision. The vibration is transmitted from the contact of the armature 5 with a yoke 1 to the yoke 1, and specific vibration is generated at each part. On the other hand, vibration waveform data of reverse phase of each part stored in a memory is read by a CPU, and vibration waveforms of reverse phase are simultaneously applied to piezoelectric elements 13a-13n mounted at the parts. Thus, the vibrations cancel each other to reduce vibration upon printing and noise.

IPC: A01B69/00
Filed: 1989-05-19
Abstract: PURPOSE:To perform steering control in high precision and response by outputting analog outputs of two directions from a sensor, constantly selecting the analog output level of the side or steep inclination where the output is highly sensitive to the change of direction angle and steering the machine body based on the selected output signal. CONSTITUTION:A machine body is steered by side clutch solenoids 45,46 for the coupling and uncoupling of right and left side clutches. The output of a control circuit 30 is connected to the side clutch solenoids 45, 46 and an automatic steering lamp 47 and the automatic steering control of the machine body is properly carried out based on the detected results of the sensors 19, 20, 21, 22. When an absolute value is calculated between a control standard value and an analog standard voltage, the difference is compared and the control is performed by using the standard value having smaller difference. In the case of performing the control using voltages corresponding to two directions, the steep position is selected on a characteristic curve and the output of the x direction voltage or y-direction voltage can be sensibly varied by a small change of the direction angle to enable the accurate steering control of the machine.
