Title: Igbt gate circuit
Inventor: YAMAMOTO SHIROJI
IPC: H02M3/00
Filed: 1992-06-02
Abstract: PURPOSE:To prevent an IGBT from voltage breakage by setting the resistance value of a gate small at normality thereby reducing switching loss, and setting the resistance value of the gate large at overvoltage, etc., thereby suppressing the maximum value of the overvoltage applied to the IGBT. CONSTITUTION:The gate circuit 2 of an IGBT 1 is constituted, being connected between the gate and emitter terminals of the IGBT. A gate resistor 20a is connected to the gate terminal of the IGBT. Moreover, as a gate on means for turning on the IGBT, a transistor 21 for gate on and a DC power source 22 for gate on, and as a gate off means for turning off the IGBT, a transistor 23 for gate off and a DC power source 24 for gate off are connected in series to the gate resistor. The gate resistor 1 has a comparison circuit 204, which detects the voltage between the collector and the emitter of the IGBT at off and compares it with reference value, and in the case of abnormality, the resistance value of the gate is changed by the switching operation of the transistor 202.

Title: Treatment of hard chrominum plating
Inventor: YOSHIMI AKITAKE
IPC: C23C28/00
Filed: 1980-10-09
Abstract: PURPOSE:To prevent generation of crack in a layer of hard chromium plating, thus, to improve the rust preventive property and the corrosion preventive property of plated metallic material by carrying out the hard chromium plating onto the surface of a layer of nitride, which is formed onto the surface of the material to be plated beforehand, after the activation of said surface has performed through the alternate electrolysis. CONSTITUTION:First of all, the surface of metallic material to be hard chromium plated, such as steel, is nitriding treated through a method such as the ionitriding method or the gas nitriding method, or the like. Since the layer of the nitride is so innert that the plating onto its surface with chromium is impossible, the surface is activated through carrying out the alternate electrolysis, which is electrolyzing in such a way as change over the rolls between the anode and the cathode every predetermined short time, in the electrolyte consisting mainly of an acid such as a solution of a chromic acid or an oxalic acid, or the like, or an alkali such as a solution of NaOH, or the like, after the nitrided surface has polished through the buffing, or the like. Through plating onto thus activated surface with chromium, the layer of the hard chromium plating in which the generation of cracking is prevented is formed, thereby, the rust preventive property and the corrosion preventive property of the material to be plated, which are due to the layer of the hard chromium plating, are improved.
