Title: Air intake-exhaust valve operation device of internal combustion engine
Inventor: NAKAMURA MAKOTO
IPC: F01L13/00
Filed: 1992-05-29
Abstract: PURPOSE:To improve responsiveness by driving an air intake valve and an exhaust valve by engine hydraulic pressure by way of providing an opening closing characteristic variable means respectively to each of the air intake valve and the exhaust valve, changing one of them to be for high speed by increase of supply oil and to be for low speed by decrease of supply oil, changing the other to be for high speed by decrease and to be for low speed by increase, and efficiently distributing working oil. CONSTITUTION:A control unit 10 outputs a control signal, changes over a valve lift characteristic of an air intake valve 5 by way of changing over a cam changeover valve, opens a fuel injection valve 6, and changes over opening closing timing of an exhaust valve 7 by way of actuating a solenoid 20 for variable valve timing control. By respectively providing valve opening characteristic variation means on the air intake valve 5 and the exhaust valve 7, the air intake valve 5 and the exhaust valve 7 are driven by supply engine oil. One of the variation means is changed over to be for high speed by increase of supply engine oil and to be for low speed by decrease, and the other variation means is changed over to be for high speed by decrease and to be for low speed by increase. Consequently, it is possible to efficiently distribute working oil and to improve responsiveness.

Title: Band-pass filter
Inventor: AOKI YOSHIYUKI
IPC: H03H7/12
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To obtain sharp attenuation characteristics and wide bands and to enable the setting of a central frequency at a desired value and the decrease ripples by providing a varactor, capable of correcting errors of a resonance frequency and a trap circuit for sharpening the cut-off characteristics. SOLUTION: Resistors R1-R3 prevent the inflow of high frequency signals to variable voltage source V1 and V2, by increasing the impedance of the variable voltage sources V1 and V2 as seen from the side of varactors B1-B3. While the voltages of the variable voltage sources V1 and V2 to be applied to the varactors B1-B3 is controlled, the resonance frequency of each resonance circuit is corrected by respectively correcting errors between inductances L2-L4 and the capacitances of capacitors C5-C7. By finely changing the voltages of the variable voltage sources V1 and V2 into optimum values, ripples on the passing frequency band of a band-pass filter are reduced. The inductor L1 and capacitor C8 or L5 and C9 respectively consists of the trap circuit, and the undesirable signal is attenuated and removed.

On the other hand, the membrane concd. water is circulated from a piping 15 to the biological treating vessel 1. The respiration rate of the activated sludge is measured by a respiration rate meter 8 and the necessary measure to maintain the low respiration rate of the activated sludge is taken at the time of membrane filtration.  Namely, the problem that the membrane flux decreases is solved if the membrane filtration is executed when the respiration rate of the activated sludge is high.
