Title: Transistor drive circuit and motor drive control device
Inventor: IKEGAWA KOHEI
IPC: H02M1/00
Filed: 2016-08-17
Abstract: PROBLEM TO BE SOLVED: To provide a transistor drive circuit capable of reducing a loss in consideration of a heat generation state of a bipolar type transistor when the transistor and a MOSFET are driven in parallel.SOLUTION: A temperature of an FET 2 is detected by a diode 15, and when the detected temperature is equal to or less than a threshold, both the FET 2 and an IGBT (Insulated Gate Bipolar transistor) 1 are turned on to perform DC assistance, and when the temperature becomes higher than the threshold, only the IGBT 1 is turned on. In concrete terms, a peak value of a voltage signal output by a temperature detector 16 is held by a peak holding circuit 17 according to the temperature detected by the diode 15, and the peak value is compared with the threshold by a comparator 18. When a gate drive voltage becomes higher than a threshold voltage during a time period in which the IGBT 1 is turned on, a gate rise determination circuit 11 outputs a trigger signal. An ON/OFF determination circuit 14 determines whether or not the FET 2 is turned on according to the comparison result of the comparator 18 when the trigger signal is input.SELECTED DRAWING: Figure 1

Title: Pulse light generator
Inventor: ISHIZUKI HIDEKI
IPC: G02F1/37
Filed: 2016-08-19
Abstract: PROBLEM TO BE SOLVED: To obtain a wavelength conversion light with high intensity.SOLUTION: A combination of a pulse laser light generator 2 with a pulse width of 1 ns or less and a laminate 6 of a crystal plate is used. Since the crystal plate has strong resistance against damage but has low wavelength conversion efficiency, when a pulse width becomes 1 ns or less, temporal concentration of energy increases to enhance laser beam intensity. Wavelength conversion is nonlinear phenomenon, and when input laser beam intensity rises, conversion efficiency is improved. With the above combination, the relationship of "laser beam intensity enhanced by shortening the pulse width×improved conversion efficiency" is obtained, thereby obtaining wavelength conversion light with high intensity.SELECTED DRAWING: Figure 1
