IPC: B01D39/20
Filed: 1991-10-24
Abstract: PURPOSE:To enhance the heat resistance and crystallization temp. of an exhaust gas filter for a diesel engine vehicle and to extend the cycle life thereof. CONSTITUTION:A ceramic fiber based on aluminum oxide and silicon oxide is bonded by an inorg. binder based on aluminum oxide and silicon oxide and having an m.p. lower than that of the ceramic fiber to form a honeycomb structure. Cells 1a, 1b are formed using a material wherein a crystal nucleus forming agent is added to a ceramic fiber and this material is wound to constitute an exhaust gas filter.

Abstract: PURPOSE:To attain communication without error even when noise and waveform distortion take place in a transmission line by using a voltage amplifier circuit comprising two transistors(TRs), two capacitors, four diodes and four resistors so as to amplify and output a pulse signal. CONSTITUTION:With a pulse signal at a point (c) set to +5V, a C2 is charged by a path comprising a TR 3, the capacitor(C)2 and a diode 4 and the potential of the C1 changes from +5V to +10V.

With a pulse signal at the point (c) set to 0V, the C1 is charged through a path comprising a diode 1, the C1 and the TR 4, the positive pole of the C2 connects to ground via the TR 4 and the negative pole of the C2 reaches -5V. Moreover, the TR 6 is turned on by a current through the C2 via a resistor R9, the TR 6 and a resistor R7, the point (f) reaches -5V, that is, the signal is amplified from 5V into 15V in terms of a peak level and the result is outputted.

Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To determine the operational phase of a specific frequency component signal accurately and to control an active filter using the operational phase signal. SOLUTION: Assuming the value of a specific frequency component signal at current point of time t1 is V1, the value of that signal at a previous sampling time t0 is V0, the phase at current point of time is ϕ, and the sampling period is TS, operational phase sin(ω0 t1+ϕ) of that signal can be determined as follows; sin(ω0 t1+ϕ)=sin[tan<-1>  (V1sinω0 TS)/-(V1cosω0 TS-V0)}]. Since the operational phase is calculated according to the formula in a digital control system, it can be determined accurately regardless of noise in the vicinity of zero-cross point. When the apparatus is applied to the digital control system for active filter, the operational phase of an AC power supply can be calculated accurately from a sampled voltage thereof thus realizing a highly accurate control.
