Title: Ac/dc power device
Inventor: NAKAHARA KAZUHITO
IPC: G05F1/56
Filed: 2009-08-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide an AC/DV power device that reduces the power loss of an AC/DC power device as much as possible using only relatively inexpensive and small components, while stabilizing output voltages.  <P>SOLUTION: In the AC/DC power device, a DC voltage obtained by rectifying an AC voltage is used as input voltage. The AC/DC power device has a potential difference detection circuit 7 that is connected in parallel with a PNP transistor Q43 serving as a main switching element. The input/output potential difference of the transistor Q43 serving as the main switching element is compared with the potential difference comparison value of the potential difference detection circuit 7. The transistor Q43 is turned on or off according to the comparison result. That is, at around the upper limit of the input voltage where a large amount of power is lost, the transistor Q43 is turned off to reduce the power losses.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Filed: 2009-08-20
Abstract: <P>PROBLEM TO BE SOLVED: To improve a yield by enabling variation-free soldering without applying large pressurizing force to an IC when solder bumps formed on the IC and lands formed on a surface of a substrate are joined together.  <P>SOLUTION: When the solder bumps 7a on the IC 7 and the lands 14a on the surface of the substrate 14 are brought into contact with each other, the IC 7 is lowered in a state where temperatures of the solder bumps 7a are held lower than a solder melting temperature, and temperatures of the lands 14a are held higher than the solder melting temperature. When a solder bump 7a which is tall comes in contact in this state, the bump 7a which comes in contact is fused soon with heat of the land 14a of the substrate 14 which is heated, and a bump 7a which is short comes in contact soon. Therefore, the respective solder bumps 7a are fused in order and variance-free soldering in even the IC 7 having variance in bump height is made possible without applying large pressuring force.  <P>COPYRIGHT: (C)2011,JPO&INPIT
