Title: Printing wire driver
Inventor: MIZUNO SHIGEKI
IPC: B41J2/28
Filed: 1989-02-28
Abstract: PURPOSE:To obtain a printing wire driver having high speed response and high reliability by composing a magnetic circuit which has an armature made of a magnetic material and a permanent magnet opposed to the armature on the rear of the armature. CONSTITUTION:An armature 9 is attracted by a magnetic flux generated from a permanent magnet 4 in a stand-by state and held in a state to be pressed to a damper 5. When a coil 6 is pulse-energized, magnetic attraction force is generated between the armature 9 and a core 1 to accelerate the armature 9, which starts rotating at a fulcrum shaft 8 as a center in a direction of an arrow C. Thus, a printing wire 10 protrudes to collide with a printing medium, thereby forming a dot. After the collision, the armature 9 is held by the damper 5 and a metal plate 11 by means of repelling force at the time of the collision and the attraction force of the magnet 4 to finish one printing process. During this process, when the wire 10 is returned after forming the dot, the armature 9 is held by the attraction force of the magnet 4. Accordingly, the impact force at the time of returning is not operated at all to rapidly damp the vibration of the armature 9 by the stable holding force, thereby performing repetitive operations at a high speed.

Title: Bearing searching apparatus
Inventor: HAMADA YOSHIO
IPC: G01S3/30
Filed: 1980-04-10
Abstract: PURPOSE:To narrow the blind zone range and prevent sensitivity from being affected by input level differences by detecting the signal reception of stationary antenna elements and controlling the sampling of the amplitude comparing outputs between the antenna elements. CONSTITUTION:The signals received by antenna elements 1-4 are detected and are made into video signals A-D which are compared in an amplitude comparator 17 formed of multiple differential amplifiers 22, 23, comparators 24, 25, etc., whereby they are made into the level magnitude detection signals of all combinations. On the other hand, the detection of the signals A-D is detected by comparison with threshold voltage in a signal detecting circuit 18, and a sampling circuit 20 is controlled by way of a timing pulse detecting circuit 19, whereby the magnitude detection signals from the circuit 17 are sampled. With this constitution, the bearing detectable sensitivity Smin is determined by the threshold voltages of the circuits 17-20 and therefore as compared to the case when they are processes by the circuit 17 alone, the blind zone is narrower. In addition, the circuit 17 has no direct relation to sensitivity, and the sensitivity is hardly affected by input level differences, thus bearing is determined stably.
