Title: Waste water treating device
Inventor: SATO ATSUSHI
IPC: C02F9/00
Filed: 1993-01-07
Abstract: PURPOSE:To extremely reduce the volume and the treatment power of a treatment water tank in a biological treatment by combining an electrodialysis device with a hydrophobic porous membrane to remove ammonia. CONSTITUTION:Waste water from which even fine suspended matter has been removed is fed to an electrodialysis device 6 where cation exchange membranes and anion exchange membranes are alternatively arranged to separate the waste water into ammonium salt concentrated waste water and ammonia removed waste water. Next, after caustic soda is added to the ammonium salt concentrated waste water to perform pH control in a tank 9, it is passed through a hydrophobic porous membrane 10 to permeatingly recover ammonia and the recovered ammonia is absorbed by sulfuric acid to form ammonium sulfate. On the other hand, after the waste water from which ammonia has been removed and the ammonia removed waste water obtained in the electrodialysis device 6 are given neutralization in a neutralizing tank 13 by adding sulfuric acid, the neutralized waste water is introduced into a biological treatment tank 14.

IPC: G02F3/00
Filed: 1989-01-10
Abstract: PURPOSE:To vary the transmissivity to incident light stepwise and to rewrite stored information by combining an electronic element which has >=2 negative differential conductance elements with a p-n junction diode having multiple quantum well structure. CONSTITUTION:Optical multistable elements each consisting of the electronic element 1 having multiple negative differential conductance with current-voltage characteristics and the p-n junction diode 2 having the multiple quantum well structure are arranged as coupling elements (synapse) between neurons in a matrix on the two-dimensional plane on a wafer to constitute an optical filter device to be used. The optical neuro-system which uses the optical multistable elements as synapses varies in the transmissivity to the incident light stepwise (many-valued logic), so the stored information (transmissivity) on the input light is rewritten on a many-valued logic basis. Consequently, when this system is applied to a super-parallel optical neuro-computer or optical parallel processing system such as a pattern recognition device, a learning function and the degree of integration are improved to obtain large effect.

Title: Rader device
Inventor: KAWAMOTO AKIO
IPC: G01S13/87
Filed: 1985-01-10
Abstract: PURPOSE:To make it possible to narrow the frequency band of a data rink and to reduce the loss of a rader video signal by switching the most significant bit of the rader data by another signal so as to be used. CONSTITUTION:A signal converter 3 and a signal regenerator 4 are used for switching the most significant bit (MSB) of a digitized primary rader video signal to a secondary rader video signal. When the video data is to be transmitted synchronously with a trigger signal, the secondary rader data is mixed with the MSB by 1/N times. Since 2 bits of the rader data are simultaneously transmitted, a loss due to a fine signal is not generated, so that the minimum receiving sensitivity of the rader is not deteriorated. The primary rader video signal is converted into a digital signal consisting of plural bits by an A/D converter. In this case, the digital signal is '1, 1, 1' at the time of maximum amplitude and '1, 0, 0' at the time of minimum amplitude. Even if the MSB is replaced at the minimum amplitude '1, 0, 0', the signal is turned to '1, 0, 0' and the analog value '1' is not changed.
