Patent Number Title Of Patent Date Issued
7078644 Resistance welding method, resistance welding apparatus, and method for manufacturing electronic July 18, 2006
In a resistance welding method and a resistance welding apparatus which prevent a decrease in bonding strength between a lead wire and a metal member due to a partially formed current flow path and which immediately removes a defective component from a manufacturing line, a plurality of
6744347 Variable resistor June 1, 2004
A variable resistor is constructed to reliably seal the space between a rotor and a substrate without insert-molding the substrate into a case, and to be produced at a very low cost. This variable resistor includes a hollow square-prism shaped case which is open at the top and the bottom
6434815 Variable resistor August 20, 2002
A first rotor and a second rotor are prepared. The first rotor has a resistor and inner-peripheral and outer-peripheral electrodes respectively connected to end portions of this resistor. The second rotor has a resistor and inner-peripheral and outer-peripheral electrodes symmetrical
6396385 Variable resistor May 28, 2002
A variable resistor includes at least two sliders fixed to the bottom of the concavity of a case, a rotor having an engaging portion for engagement with a tool, on the upper side thereof and rotatably received in the concavity of the case, a resistor substrate having a resistor and an
6111493 Variable resistor August 29, 2000
A variable resistor comprises a case, slide contactors, a rotor, a metal cover and lead terminals. Arms which are respectively provided at central portions of the slide contactors protrude from a bottom surface of a recess portion of the case and are each shaped like a comb. The arms are
6016098 Variable resistor January 18, 2000
A first rotor and a second rotor are prepared. The first rotor has a resistor and inner-peripheral and outer-peripheral electrodes respectively connected to end portions of this resistor. The second rotor has a resistor and inner-peripheral and outer-peripheral electrodes symmetrical
5790012 Variable resistor August 4, 1998
There is provided a variable resistor having a small number of parts and having an excellent heat releasing property. A rotor is rotatably contained in a concave portion of a case. The rotor has a resistive element provided on the bottom thereof and electrodes connected to both ends
