Title: Low pass filter circuit
Inventor: OOTAKI KIYOSHI
IPC: H03H11/12
Filed: 1983-09-02
Abstract: PURPOSE:To prevent deterioration in an output signal by connecting a high pass filter and a resistor in parallel so as to constitute a low pass filter. CONSTITUTION:A cancellation circuit having a characteristic of a high pass filter is constituted by using an amplifier 3, resistors R7, R8, capacitors C7, C8 and an inductor L. An input signal is fed to the cancellation circuit and also to a resistor R6, the output of the resistor R6 and an output of the cancellation circuit through a resistor R10 are synthesized and extracted as an output. The phase of a signal of a sub-region among signals applied to an input terminal 1 is opposite for a signal through the resistor R6 and a signal through the resistor R10, the signals are cancelled and they are not obtained at an output terminal 2. The signal of audible band extracted from the output terminal 2 has no deterioration because it has not passed through any filter.

Filed: 1988-06-29
Abstract: PURPOSE:To improve slip properties without damaging the characteristics of a film by adding a silicone resin fine powder in a coating layer. CONSTITUTION:A composition based on an ionizing radiation curable hydrophilic monomer and/or oligomer (prepolymer) is applied to the single surface or both surfaces of a film.
