Title: Dc high tension power supply device
Inventor: TOYAMA ISAO
IPC: H02H3/087
Filed: 1987-10-09
Abstract: PURPOSE:To enable the high-speed interruption of only output current and high-speed re-making to be performed, without permitting short-circuit current for short-circuiting a power source directly, to flow, by connecting a plurality of transistors in series to a space between a smoothing circuit and a load. CONSTITUTION:When a load 9 is set in a short-circuited state, then short-circuit current does not flow to a degree equal to or more than collector current set by the product of the base current of transistors 111-11n and a current amplifica tion factor, and the whole voltage is instantly applied to a transistor stack 7. However, a driving power source 10 is interrupted within several mus by short- circuit detection signal from an excess current detector 8, then short-circuit current is interrupted. Energy consumed in the transistor stack 7 at this moment is less, and the power transistors of the collector loss of several hundred watts have the heat capacity of several 10mJ-100mJ and are in a sufficient safety use range.

Abstract: PURPOSE:To improve the assembling easiness and to realize mass production of sensors by providing a cylindrical inner side wall which is extended with an inclination of a predetermined angle in the axial direction to the axial center from the inner peripheral end of an annular bottom wall in a container part. CONSTITUTION:A sensor 1 is provided with an annular piezoelectric element 3, an annular electrode 4 overlapped with the piezoelectric element 3, and a main metal fitting 2. One end in the axial direction of the metal fitting 2 is opened, while the other end is closed.
