Title: Treatment of sludge
Inventor: HASEGAWA SUSUMU
IPC: C02F11/02
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To improve the maintenance cost and safety of the treatment by forming an enzyme(s) capable of decomposing organic matter in sludge to solubilize suspended solid in the sludge and/or degrade it into lower molecular weight substances and to digest the sludge. SOLUTION: In this treatment, one part or all of sludge and/or microorganisms having sludge decomposing enzyme formation activity are thrown into an enzyme formation tank 1 and a liquid contg. an enzyme(s) formed from the microorganisms by cultivating them is transferred to a solubilization tank 2. If there is the other part of the sludge which is not thrown into the enzyme formation tank 1, this part of the sludge can be added to the solubilization tank 2. The sludge is solubilized and/or degraded into lower molecular weight substances in the solubilization tank 2 and thereafter, the resulting mixed liquid is supplied to a digestion tank 3 placed next to the solubilization tank 2 and when the digestion of the mixed liquid is completed, the digestion product can be discarded as a liquid and a gas.  Thus, the total residence time required for the treatments in the solubilization tank 2 and digestion tank 3 can be reduced and therefore, the objective treatment can rapidly be completed and further, is excellent in cost and safety because the need of using large amounts of expensive or dangerous chemical agents is eliminated.

Filed: 1992-09-30
Abstract: PURPOSE:To reduce driver's burden and to attain generous drive and safe operation by providing this vehicle traveling mode changing device with a means for changing the operation mode of a drivers own-vehicle in accordance with the traveling state of the preceding vehicle. CONSTITUTION:A reference distance in a current operation mode is inputted from a storage device 4 to a comparator 5 by depressing a backup push-button on a command device 3 in a stopped state on a backup road. Only when an output is generated from the device 3, the device 4 inputs an output from a distance information acquiring device 2 and stores it as a reference distance. On the other hand, an inter-vehicle distance between the self-vehicle and the preceding vehicle is inputted from the device 2 to the comparator 5. When a detected distance exceeds the reference distance, the comparator 5 outputs the input signal to an output device 7 as it is. The device 7 generates an alarm based upon the input. In traveling, the reference distance is inputted to the device 4 by the device 3 and a change between the practical inter-vehicle distance and the reference distance is found out and outputted to the device 7. Consequently automatic follow-up operation to the preceding vehicle can be attained.

Title: Transmitter for decoding signal
Inventor: KATO SHIRO
IPC: H04N19/85
Filed: 1992-09-30
Abstract: PURPOSE:To prevent S/N from being deteriorated even when coding/decoding is repeated by coding a difference between a decoding signal and a signal obtained by limiting its amplitude of the signal within a prescribed range and transmitting a resulting output signal. CONSTITUTION:A decoding signal inputted from the input terminal 101 of a transmitter 115 a signal whose word length is 9-bits not subjected to a limiter processing to 8-bits. The decoding signal is limited to a value in a range of -128 to 127 by a limiter circuit 102 to become a 1st signal whose word length is 8-bits. Furthermore, a subtractor circuit 103 subtracts a 1st signal from the decoding signal to obtain a difference signal. The difference signal is coded by an encoder 105 and a 2nd signal (an output in the unit of 2-bits) is obtained. Since the decoding signal subjected to the limier processing as usual is obtained at a reception side and the transmitter is compatible with a conventional transmitter and the decoding signal without limiter processing is regenerated, the deterioration in the signal due to the repetition of coding and decoding is suppressed.

Title: Surface treatment of wood
Inventor: TAKAHASHI HIROSHI
IPC: B27K5/00
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To save labor for treatment without adverse chemical effects and improve durability and fire resistance, retaining a natural wooden beauty such as vein as it is by applying a unique surface treatment to the surface of wood without the use of a chemical or a coating material and thereby, discoloring the wood to a sunburnt appearance state and also modifying its quality. SOLUTION: The surface of wood is discolored to a sunburnt appearance state and is modified in quality by irradiation with ultraviolet rays without the use of a chemical or a coating material. As a result of this irradiation of the wood with ultraviolet rays, the part, to which the ultraviolet rays are emitted, of the wood turns yellow or yellowish brown and consequently, the surface tissue of the wood changes to have such a nature that it is hardly susceptible to an external influence. The surface color of the wood can be arbitrarily adjusted by the intensity of the ultraviolet rays to be emitted and their emission time, so that a finished product, if it is of the identical type, can be uniformly manufactured in the same color regardless of its quantity.  Thus it is possible to inhibit the dispersion of an antibacterial active component or an aromatic component such as hinoki thiol contained in the wood on account of a change in the surface itssue and consequently, maintain the essence of the wood for a long time.

Abstract: PURPOSE:To improve electromagnetic conversion characteristics by using a ferromagnetic alloy powder as a ferromagnetic powder in the most upper layer and specifying a ferromagnetic powder in lower magnetic layers to cobalt- containing iron oxide having 35m<2>/g or more of specific surface area by BET method. CONSTITUTION:The ferromagnetic powder in the most upper layer is a ferromag netic alloy powder and the ferromagnetic powder in lower magnetic layers is cobalt-containing iron oxide having 35m<2>/g or more specific surface area by BET method. Since the ferromagnetic alloy powder is used in the upper layer, good characteristics in a high range, namely, pictures of high quality can be obtained with high Bm (maxmum magnetic flux density) and high Br (residual magnetic flux density). As the iron oxide powder used in the lower layers shows better dispersibility compared to the ferromagnetic metal powder, the surface properties of the layers can be improved. Thus, electromagnetic conversion characteristics are improved.

Filed: 1985-11-21
Abstract: PURPOSE:To realize the same carrier injection characteristics as a hetero-junction, using an amorphous layer on an adhesive interface as a tunnel insulating film by directly mirror polished-surfaces in two semiconductor substrates mutually under the state of crystal lattice matching. CONSTITUTION:A first Si substrate 1 is formed in three layer structure of an n<+> type layer 11, an n<-> type layer 12 and a p-type layer 13, and a second Si substrate 2 consists of an n<+> type layer. Surfaces to be bonded in these two substrates are mirror-polished, and the surfaces are brought into contact mutually, and thermally treated for 1hr at 1,100 deg.C and unified. An amorphous layer in approximately 30Angstrom  is shaped on an adhesive interface 3. Thickness on the substrate 2 side is adjusted by employing an n-p-n wafer acquired in this manner, and the wafer is processed to a predetermined pattern to form emitter electrodes 4, a base electrodes 5 and a collector electrode 6. The extremely thin amorphous layer is shaped on the adhesive interface 3. The amorphous layer has semi-insulating properties, but is can be ignored approximately as a resistance component because it is extremely thin, and it functions as a tunnel insulating film. Accordingly, a high current amplification factor is obtained by the same principle as a hetero-junction transistor.
