Title: Removal of nutritious salt by aquatic plant cultivated on artificial cultivation ground
Inventor: KONDOU MOTOKI
IPC: C02F3/32
Filed: 1980-09-06
Abstract: PURPOSE: To absorb and fix nutritious salts contained in water, by holding a cultivation rack unit in the water at a depth where sun light can reach, and setting an aquatic plant onto the cultivation implantion modules of said unit on land.  
     CONSTITUTION: An artificial cultivation ground, comprising a cultivation rack unit 1 and detacable cultivation implantation modules 2, is used. The aquatic plant can be cultivated under a good condition in the broad range of a lake, swamp, inland sea or the like where eutrophication is promoted, not only at a relatively shallower level from the shore where the aquatic plant can easily grow thick but also a deep water level where even the growth of an sinking plant would be difficult or impossible. The grown-up aquatic plant 6 is completely recovered by landing together with the module 2. The substances which the aquatic plant absorbed and fixed in its body can be completely removed on land. Thus, the effect of nutritious salts removal can be attained.

Filed: 1992-04-18
Abstract: PURPOSE:To prevent a decrease in an output maximum torque by altering a limiting value of a torque command in response to a speed of an AC motor. CONSTITUTION:A processor for controlling a motor executes a speed loop processing. First, a speed command vc and a feedback value fv of a real speed of a motor detected by a speed detector, etc., are read. Then, a current limiting value I1im is calculated. The value I1im for the speed of the motor may be stored in a table, and subsequently read out. A speed loop processing is executed similarly to prior art based on the read command vc and the value fv, and a torque command is obtained. The value I1im is compared in absolute value with the torque command, a smaller one is delivered to a current loop as a torque command Tc to end the speed loop processing. A current loop advances the phase according to an electric angle position theta of a rotor and a real speed of the motor detected similarly to the prior art, determines a torque command for each angular phase, current loop processes to drive the motor.

Abstract: PURPOSE:To relieve the adverse effect given from a spurious output in the vicinity of a carrier by selecting a local oscillating output of a local oscillator to an integral number of multiple of a reference frequency being an input to a phase comparator of a PLL. CONSTITUTION:Part of an output f0 of a voltage controlled oscillator 11 is mixed by a mixer 12, and a local oscillating frequency fL of an output of a local oscillator 2 for mixing-down to frequency-divide the frequency into 1/N is selected to an integral number of multiple of a reference frequency f0 being an input of a phase comparator 15.
