Filed: 2002-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a gate drive circuit for a voltage drive type semiconductor element which is low in power loss, and can suppress surge voltage at switching.  <P>SOLUTION: When a control signal is inputted, a bipolar transistor Q3 (hereinafter, simply called a 'transistor') is turned off, and transistors Q1 and Q2 are turned on, and the gate current of a switch element M1 flows in parallel via resistors R1 and R2, and gate voltage drops suddenly, and the current of the load L1 connected to the switch element M1 decreases rapidly. The change rate of the drain current of the switch element M1 becomes small, and the surge voltage is suppressed by detecting the overvoltage generated between the drain and the source of the switch M1 due to the parasitic inductance L2 of wiring due to the rapid decrease of load L1 with a Zener diode ZD, and operating a transistor Q4 so as to make a current flow to a resistor R5, and raising the base potential of a transistor Q2 so as to switch it off, and limiting the gate current of the switch element M1 to flow only to a resistor R1.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for laser processing
Inventor: OKUNO TETSUO
IPC: B23K26/00
Filed: 2002-05-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for laser processing which can precisely process a work piece while maintaining the working surface state of the work piece good.   <P>SOLUTION: The method for laser processing comprises a step of emitting the THG (third harmonic wave) of an Nd:YAG laser D (or Nd:YV04 laser) of a solid state laser to the work piece. Thus, the smoothness of the surface of the work piece after processing with extremely small dirt, burr, dross or the like due to scattering of a molten material is assured. Further, the heat accumulation effect when the laser is emitted is small due to a short pulse width. The depolarization of the piezoelectric material of the work piece is eliminated, and hence the driving efficiency of an ink jet head 120 is raised.  <P>COPYRIGHT: (C)2004,JPO
