Title: Sample holding circuit
Inventor: KOO SHINZOU
IPC: G11C27/02
Filed: 1980-02-15
Abstract: PURPOSE:To obtain a circuit a circuit suitable for the measurement specially for a waveforme whose input time is short, by minimizing a charging potential difference during sampling operation, by storing the previous sampling output in a register. CONSTITUTION:When switch 3 is turned on and switch 8 is turned off under the control of timing control circuit 5, input signal 6 is charged into capacitor 2. At this time, since the sampling time is short, capacitor 2 is not charged up to the input signal voltage. With switch 3 turned off, the output voltage of line 7 is AD-converted by AD converter 4. Next, the output of AD converter 4 is stored in register 10, and that of register 10 is inputted to DA converter 9. Further, once the output voltage of DA conerter 9 is set, switch 8 is turned on and with the output of Da converter 9, the output of line 7 is held until the next sampling. As a result, the charged potential difference of capacitor 2 is decreased in the 2nd sampling.

Title: Liquid agitating apparatus
Inventor: KINOSHITA DAIJIROU
IPC: C25D21/10
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To set a maximum agitation speed efficiently by monitoring the rotation of a magnet while the number of revolution of a magnetized agitating rotor in the bottom part of a liquid receiving container being increased and monitoring the wave shape of the output signal of a magnetic sensor. SOLUTION: In a liquid agitating apparatus, an agitating rotor 4 rotates conforming to a magnet 5 when the rotation speed of a motor 6 is relatively low, the magnetic force of the magnet 5 overlaps with that of the rotor 4, and a peak in every wave crest appears periodically in the detection of a magnetic sensor 7. The rotor 4 receives greater resistance from liquid 3 as the number of revolution of the motor 6 increases and rotates at a lower speed than the magnet 5 so that the magnetic force of the rotor 4 is detected later separately, and in the wave shape of an output signal, one peak in every two crests appears in each pole. By a process in which the number of revolution of the motor 6 is increased gradually and the output wave shape of the sensor 7 is monitored, the maximum number of revolution of the rotor 4 can be set up easily and, automatically, without step-out.

Title: Aerobic purification
Inventor: KAWABATA MASAHIRO
IPC: C02F3/06
Filed: 1982-02-12
Abstract: PURPOSE:To perform aerobic purification at a low cost while omitting a tank for waste washing water, by providing a distribution cell in piping communicating a fixed-bed catalytic oxidizing cell with a means for separating turbid substance, and communicating the distribution cell to a cell for reserving waste water the piping. CONSTITUTION:Water to be purified is let flow through a connecting pipe 13 to an overflow gate 14. It does not overflow beyond the overflow gate 14 if its flow amount is suited to the purification of waste water, but entirely flows into a means 4 for separating turbid substance. The water to be purified is made slightly turbid by turbid substance based on aerobes being gradually stripped from a packed layer 6, but said turbid substance is precipitated at the lower part of a precipitating cell 9 so that serene purified water is withdrawn through a purified water pipe 21. With the progress of purification, the aerobes adherent to the packed layer 6 become swollen and cause the plugging of the packed layer 6. Hence a fixed-bed catalytic oxidizing cell 2 is washed.
