Title: Wire bender for welding
Inventor: UKAI JIYUN
IPC: B23K9/12
Filed: 1981-02-27
Abstract: PURPOSE:To make the spiral twisting quantity of a welding wire constant irrespectively of wire speeds and to make the width of beads constant by making the number of revolutions of a straightening mechanism for the welding wire proportional to the feed speeds of the welding wire. CONSTITUTION:A wire 1 for welding fed to a welding torch 4 generates the arc between the works 6. At this time,the wire 1 is fed with a driving roller 3a; at the same time, a DC motor 15 is driven to turn a rotating body 11 in a fixed direction with bevel gears 12b, 12a. While displacements are given to the wire 1 with a deforming roller 10, twists are given thereto wuth the body 11, by which spiral bending habits are given to the wire. At this time, the number of revolutions of the DC motor 15 is made proportional to the wire feed speeds by a wire feed motor 2. The deformation quantity of the wire is made constant irrespectively of the wire feed speeds.

Title: On load voltage regulator
Inventor: YAMASHITA KOUJI
IPC: H01F29/04
Filed: 1982-02-24
Abstract: PURPOSE:To make installation simple by making a reactor compact and the occupied spacing smaller by a method wherein a plurality of current limiting reactors are integrated in parallel in such a manner that positive reactance is generated between the adjacent current limiting reactors. CONSTITUTION:A changeover switch S with the antiparallel connection of SCR's and a current limiting reactor L are connected to each tap(t) of voltage regulating winding 1A in series and linked with an input terminal 2, while the other end of the winding 1A is linked with an input terminal 2'. The reactors are arranged with the terminals of the same polarity on the same side and adjacent to each other with the axial line being made identical. When a changeover switch S1 conducts and a tap t2 is selected by conducting a switch S2; S1 and S2  are simultaneously fired so that transversal current Is is generated in the order  of S1-L1-L2-S2. However, the magnetic flux produced in L1, L2 has the same direction and consequently the transversal current Is is remarkably suppressed. At this time, after temporary short-circuiting, the switch S1 is cut off and only the switch S2 conducts so as to complete tap switching. For this reason, each reactor L can be made compact and the number of assembling processes can be minimized.

Title: Method for trimming piezoelectric element
Inventor: YASUTOMI HIDEO
IPC: B41J2/045
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for trimming a piezoelectric element whereby a load of a driver can be lessened and costs of manufacturing can be reduced. SOLUTION: According to the method for trimming of PZTs, the amount of polarization of each of a plurality of PZTs of an ink-jet head is trimmed by a laser. When a laser light is projected to a laser light illumination part as indicated by an arrow 108, the heat is transmitted locally inside a PZT 315 as indicated by a dotted line 107. A polarization of the PZT 315 locally reaching a Curie point is negated. In practice, after a test printing, the laser light is projected to PZTs 315 corresponding to other ink channels than one discharging ink of a minimum dot diameter which adheres to a recording sheet at the test printing, thereby adjusting the amount of polarization of the PZTs. In this manner, a displacement of the PZTs 315 is adjusted and a dot diameter of ink flying out from ink channels and adhering to the recording sheet is made uniform.
