Title: One-transistor type switching power source
Inventor: OOISHI HIROTO
IPC: H02M3/335
Filed: 1983-09-26
Abstract: PURPOSE:To increase the withstanding margin of a switching transistor by absorbing a flyback energy by a capacitor. CONSTITUTION:When a switching transistor Q is turned OFF, energy stored in a choke coil L is smoothed through a commutation diode D4 by a choke L and a capacitor C2. The flyback energy stored in a transformer 2 is not discharged to the secondary side at the primary side when OFF, but particularly a spike voltage of the flyback energy is reduced by a capacitor Cx connected to the primary side of the transformer 2. Thus, the withstand voltage margin of the switching transistor can be increased, thereby improving the reliability.

IPC: H01J37/147
Filed: 1988-07-18
Abstract: PURPOSE:To contrive the flattening of a strength distribution of an irradiation field by applying alternating voltage which is mutually different in a cycle and becomes integer to an X and Y axis scanning electromagnets and scanning so as to turn back charged particle beams in the irradiation field plural times. CONSTITUTION:An X axis scanning power source 3 and a Y scanning power source 5 apply X axis voltage VX and Y axis voltage VY on each scanning electromagnet 2, 4. At this time the voltages VX and VY are square waves, the cycle of the voltage VX is 80m.second, the cycle of the voltage VY 20 m.second and the cycle of voltages VX is set four times the cycle of the voltage VY. Thereby X axis current IX and Y axis current IY composed of a triangular wave flow in the electromagnet 4. Therefore an irradiation field F in which a strength distribution B is flattened is formed as a charged particle beam 1 is turned back plural times. In this case, because the particle beam 1 is directed into the irradiation field F, the strength distribution of the particle beam 1 is set comparatively narrow and therefore unnecessary energy strength is lessened and the irradiation field F can effectively be flattened because the distribution of a peripheral part G is narrow to the irradiation field of fixed size.
