Title: Switching semiconductor module for power
Inventor: OKUMURA SABURO
IPC: H03K17/16
Filed: 1992-08-26
Abstract: PURPOSE:To prevent the occurrence of overshoot noise by forming a bypass for the current flowing to an input capacity at the time of switching from turning-on to turning-off of a switching element for power. CONSTITUTION:When signal sources 17 and 18 are turned off and on respectively, a semiconductor element 1 is switched from turning-on to turning-off, and a semiconductor element 2 is switched from turning-off to turning-on. At this time, a diode 25 is turned off, and the discharging current of an input capacity 13 flows through the emitter and the base of a transistor TR 23 and a resistance 27, and the element 1 is turned off by the reduction of the voltage between the gate and the emitter, and the TR 23 is turned on. Thus, the current bypass of the capacity 13 is formed from a terminal 10 through a feedback capacity 15, and excessive recharging is stopped, and a voltage Vge between the gate and the emitter of the element 1 is kept lower than the saturation voltage between the collector and the emitter of the TR 23. Consequently, the voltage Vge does not rise to a threshold voltage, and overshoot of transient voltage oscillation does not occur, and the occurrence of noise is prevented.

Title: X-ray analyzer
Inventor: FURUMI HIDETO
IPC: G01N23/22
Filed: 1990-09-21
Abstract: PURPOSE:To make it possible to suppress the effect of an electron beam which is irradiated on a sample on an orbit to the required minimum degree by arranging an electromagnet as a means for generating a magnetic field for removing scattering electrons in front of a detector, and variably controlling the excitation. CONSTITUTION:A sample S is measured at several points in the arbitrary range of the wavelength of an X-ray spectroscope. Then, the maximum exciting current where the detected output of X rays becomes lower than the preset lowest value is obtained based on the relationship between the exciting current for an electromagnet M at each wavelength position stored in a CPU and the output of an X-ray detector D. The relation table of the maximum current and the wavelength position of the X-ray spectroscope is stored in a RAM 6. At this time, the starting wavelength position of the X-ray spectroscope is set at one end of the range wherein wavelength scanning is performed for the sample S. Each wavelength position at the halfway is selected from the wavelength positions where the X-ray peak is not present at an equal interval. As a result, the output of the detector D is only the background component of the X-ray spectrum. Therefore, the exciting current of the electromagnet M is obtained so that the output becomes the value lower than the specified level.
