Title: Solenoid actuator with loose-fit armature
Inventor: CLIFT MICHAEL
IPC: H01F7/16
Filed: 1983-09-01
Abstract: A solenoid has a coil (11) operating on an armature (12) and shaft (15), moving in co-operating bores in a mild steel housing. In order to reduce or prevent hum or chatter of the armature and shaft, their clearances in the bores are increased, e.g. to provide 0.48 mm clearance on each side of the shaft 15 and 0.45 mm on each side of the armature 12. Thus a degree of instability is built into the armature and shaft such that they tend to fall into a tilted position contacting the bores at either end. This bridges the air gap forming a complete magnetic path holding the armature and shaft stationary. A portion 32 of the armature has a closer tolerance in the bore. The actuator may be part of a valve. <IMAGE>

Title: Printer
Inventor: KIKUGAWA NORIYUKI
IPC: B41J7/34
Filed: 1984-02-13
Abstract: The printer selects a character by moving a type wheel by a stepping motor. Phases other than a stable phase of windings of the stepping motor are shorted eg by switches SW1,SW2 when a rotor of the stepping motor comes to a vicinity of a stable point of a target phase. The energisation of the stable phase winding is then interrupted for a predetermined period and then its energization is gradually increased, eg by a pulsed waveform whose pulse width gradually increases with time. This arrangement damps oscillation of the rotor about the stable point. <IMAGE>
