Title: Pass band variable low pass filter
Inventor: FUJIMARU MIKIO
IPC: H03H11/04
Filed: 1988-09-26
Abstract: PURPOSE:To set the low frequency cut-off to a low value by increasing the capacity of a small-capacity capacitor by the Miller effect (the capacity is multiplied with the amplification factor of a variable gain amplifier). CONSTITUTION:This device consists of an input terminal 100, an output terminal 101, a transistor TR 1, a resistor 7, and first to fourth diodes 2 to 5. Feedback is applied to the variable gain amplifier by a capacitor 8 to increase the capacity of the small-capacity capacitor by the mirror effect. Thus, the low band cut-off frequency can be set to a low value without using a large-capacity capacitor. This cut-off frequency is changed by changing the amplification factor of the variable gain amplifier.

Abstract: PURPOSE:To improve mechanical strength by installing shaft supports only on the single side of a shielding vessel, and forming a telescopic structure of a movable seat on the retaining part of the support for a vacuum vessel, via a rolling member so as to be movable in the direction rectangular to the support. CONSTITUTION:Outer-side axial supports 6 are installed only on the single side of a radiation shielding vessel 2, and retain a coil vessel 3, from a vacuum vessel 1 via the vessel 2, or directly so as to penetrate the radiation shield. A retaining part for the other side vessel of the tip of the support 6 is formed in a telescopic structure movable in the direction rectangular to the support 6, and retained with a steel ball 10.
