Title: Manufacturing method of lead frame for semiconductor device
Inventor: TANAKA HISAHIRO
IPC: H01L23/50
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To avoid the decline in the solder wettability of Pd or Pd alloy film, by a method wherein a lead frame formed of Pd or Pd alloy film on a platelike raw material in water solution of an electrolyte is used as a cathode to make a potential difference from an anode for producing hydrogen, by supplying a current for a specific time in a specific density. SOLUTION: In a water solution containing an electrolyte, a lead frame formed of a Pd2 film or Pd alloy film on a planner raw material is assumed as a cathode to make a potential difference from an anode as the counter electrode to reform the lead frame, by the hydrogen produced by supplying a current for a specific time in a specific density. In such a constitution, the decline in the solder wettability of Pd or Pd alloy film can be avoided by restoring an oxide formed by the high temperature thermal stress, in the junction time of a semiconductor device to a metal by the reducing action of the hydrogen absorbed in the Pd film 2 or Pd alloy film.

Title: Headlamp lighting device for vehicle
Inventor: SAKATA MASAO
IPC: H02M7/48
Filed: 1990-03-02
Abstract: PURPOSE:To perform proper hot restart by controlling currents flowing to the electric discharge lamp-bulb with the integral values of an integrating means for integrating currents of primary winding of a transformer to discharge the currents at a specified time constant. CONSTITUTION:When a switch 2 is turned ON when an electric discharge lamp 5 is at a low temperature after a long time has elapsed after lights-out, a capacitor 12 has been discharged, and input voltage of a control circuit 6 is zero. At this time, a control circuit 6 sets an oscillating circuit 7 into oscillation at a low frequency to turn a transistor 8 ON/OFF at a low frequency. The secondary winding side of a transformer 3 has a low impedance with respect to a low frequency, so that a high current flows to heat up the electric discharge lamp in a short time, and lighting is stabilized. An integration constant determined by resistances 9, 10 and the condenser 12 is taken to be equal to the temperature time constant of the electric discharge lamp 5. When the lamp is lighted immediately after lights-out, the oscillating circuit 7 is oscillated at a high frequency by residual charge of the capacitor 12, and a high current does not flow to the electric discharge lamp 5. Proper hot start can thus be performed.

Abstract: PURPOSE:To prevent leakage of combustible gas at a device, which is packaged while including at least a fuel cell for air cooling its inside, by furnishing a combustible gas sensor in the neighborhood of the outlet for the cooling air. CONSTITUTION:Air cooling is applied to a power generating plant, which accommodates a fuel cell 1 in a lump package 6 together with, for ex., a fuel supply device 2 and a DC/AC converter 4. The external air 11 inhaled from a suction hole 8 through a cooling fan 7 undergoes heat exchange and is exhausted from the outlet 9 for cooling air. In case the combustible gas for operating the fuel cell 1 has leaked into the package 6, it is sensed by a combustible gas sensor 10 in the neighborhood of the air outlet 9 before the leak gas disperses into the external air to be diluted. The location ofd this gas sensor 10 may be either outside or inside of the package 6 as long as in the neighborhood of the air outlet 9. This prevents accident such as explosion of the leak gas.
