Title: Electromagnetic printing head
Inventor: KIMURA NOBUO
IPC: B41J2/28
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To improve an abrasion resistance of a spring disc by changing a shape of an armature spacer which functions as a fulcrum action to the spring disc formed inside a printing head. SOLUTION: An excitation coil 8, a printing wire 9 and an armature 4 constitute one set element. The printing wires 9 are arranged in two longitudinal arrays. 24 sets of the elements are arranged radially in the printing head. Moreover, an end face of a leading end part of an armature spacer 2 at the side in contact with a spring disc 1 is rounded by a predetermined curvature in a sectional direction. In other words, the armature spacer 2 is subjected to press working, and then an outer circumferential face in the sectional direction is rounded 5 from a corner by barrel polishing or the like. The operation of the spring disc 1 at an edge face of the armature spacer 2 is thus eliminated. The armature spacer 2 accordingly functions as a fulcrum part 3 of the spring disc 1.

Abstract: PROBLEM TO BE SOLVED: To completely prevent the mixing of the condensed water of high-temp. vapor with the condensed water of vapor by compressing the vapor generated from an aq. soln. in an evaporator with a vapor ejector, utilizing the vapor again as a heating source and condensing the vapor by isolating the same from the high-temp. vapor which is a drive source of the vapor ejector in a water evaporator. SOLUTION: The vapor generated from the aq. soln. in the evaporator 11 is sent via a duct 29 to the heat exchanger 18 of the water evaporator 16 where the condensed water is heated and evaporated and is simultaneously condensed. A part of the vapor generated from the condensed water by heating of the heat exchanger 18 is sucked and compressed by the vapor ejector 23 driven by the high-temp vapor as the drive source and is then sent together with the high-temp. vapor via a vapor duct 26 to the heater 12 of the evaporator 11 where the vapor is utilized as its heating source. On the other hand, the remaining part of the vapor is sent via a branch duct 25a to a condenser 17 where the vapor is condensed.  The vapor generated in the evaporator 11 is condensed only by the heat exchanger 18 in such a manner and, on the other hand, the high-temp. vapor which is the drive source of the vapor ejector 23 is condensed in the heater 12 without arriving at the heat exchanger 18.

The upper stepped part 6 has the function for causing an annular air gap 8 corresponding to the stepped difference at the time of passing the molten metal solidified layer 50 whose the outer shape is formed by being solidified below the stepped part 60 through the stepped part 6 to drastically reduce the cooling action of the sleeve 2. Then, the cooling mold 1 is set so that the upper stepped part 6 in the sleeve 2 always positions at the part lower than the molten metal surface by 5-15mm.  The molten metal 5 entered into the sleeve 2 from the lower end opening hole of the sleeve 2 is cooled and solidified by coming in contact with the sleeve 2 and intermittently pulled up.
