Title: Printing head for dot printer
Inventor: ISOBE MINORU
IPC: B41J2/28
Filed: 1979-05-11
Abstract: PURPOSE: To reduce the production cost, number of assembling steps and installation space of the device by a method wherein the magnetic field of a ring-shaped permanent magnet common to plural pieces provided in a magnetic path is divided and the end portions of a ring-shaped leaf spring of which the end portion is divided in plurality are attracted.  
     CONSTITUTION: When no current is supplied to a magnet coil 4, the end portions 7a of a leaf spring 7 are attracted toward the core 2 of an armature pin 9 due to the magnetic force of a permanent magnet 3, the end portions 7a of the spring 7 being deviated. With the magnet coil 4 supplied with current, the magnetic field of the magnet coil 4 cancels that of the permanent magnet 3, so that the armature pin 9 on the spring 7 is no longer attracted toward the core 2. Accordingly, the end portions 7a of the spring 7 are released from deviation, and a print wire 8 fixed to the tip end of the spring 7 is driven and guided along a pin guide 11. Then, with the current supply for the magnet coil 4 interrupted, the armature pin 9 on the spring 7 is reattracted toward the core 2 due to the magnetic force of the permanent magnet 3.

IPC: B05B5/08
Filed: 1982-04-09
Abstract: PURPOSE:To prevent the deterioration of paint, by sucking and removing paint in a paint-supply conduit and a paint-spray nozzle by a means for sucking paint. CONSTITUTION:Paint-supply conduits 31, 36 are connected to a means 42 for sucking paint, and paint in the paint-supply conduits 31, 36 and a paint-spray nozzle 11 are sucked and removed by the means 42 for sucking paint at the time of stopping the supply of paint. Since the major part of the paint left in the paint-supply conduits 31, 36 and the paint-spray nozzle 11 is sucked and removed at the time of washing operations for changing a color, the scattering of the paint to the surroundings is prevented at the time of washing operations. As a result, the quality of a coating film on a coated surface is not deteriorated since the scattered paint would neither adhere to the main body of the coater nor fall down as liquid drops, and the formation of an electric leak or the like caused by the adhesion of metallic paint can be prevented.
