IPC: H03K5/15
Filed: 1990-03-09
Abstract: PURPOSE:To generate two kinds of rectangular waves having a phase difference of 90 deg. by integrating a rectangular wave generated in a rectangular wave oscillation circuit at an integration circuit to generate a sawtooth wave and using a waveform shaping circuit to convert the sawtooth wave into the rectangular wave. CONSTITUTION:A hysteresis circuit 30 composed of an operational amplifier 6 and resistors Rg, Rh, is connected to a point B at the output of an integration circuit 20 via a voltage follower composed of an operational amplifier 5. The hysteresis circuit 30 shifts a reference voltage Vr for giving a slicing level to the output waveform of the integration circuit 20 positively or negatively. When a waveform B rises, the reference voltage Vr is boosted by a voltage Vs and when the waveform B is decreased, the reference voltage Vr is decreased by the voltage Vs. Thus, the output of the integration circuit 20 is sliced by a voltage Vr+Vs or Vr-Vs to be a waveform as shown in symbol C whose phase is shifted accurately by 90 deg. from a rectangular wave shown in symbol A.

Filed: 1980-04-30
Abstract: PURPOSE: To prevent the collapse of the cake formed in a filter chamber and supply raw liquid continuously by using two pressure tanks and maintaining these in a pressurized state alternately thereby maintaining the raw liquid supply pressure to a pressure filter constant.  
     CONSTITUTION: When the raw liquid supplied into a pressure tank 16 reaches an upper limit, a valve 18a closes and a valve 20a opens to put the tank 16 in a pressurized state. During this time, compressed air is introduced into a pressure tank 15, and raw liquid is being supplied to a filter 14. When the liquid level in the tank 15 reaches a lower limit, the raw liquid is supplied from the tank 16 to the pressure filter 14, thence the air in the tank 15 is released into the atmosphere through a release pipe 17 so that the tank 15 is normal pressures. When the raw liquid is supplied into the tank 15 and the liquid level reaches the upper limit, the tank remains standing by in the pressurized state until the liquid level in the tank 16 reaches the lower limit.
