Title: Production of concentrated and dried surfactant
Inventor: KATO DAISUKE
IPC: C09K23/00
Filed: 1997-12-06
Abstract: PROBLEM TO BE SOLVED: To obtain a concentrated and dried surfactant in one stage and to thereby reduce energy and the space of equipment by feeding an acidic solution containing an anionic surfactant precursor and a neutralizing alkali solution into a film evaporator. SOLUTION: An acidic solution containing an acid precursor of an anionic surfactant and a neutralizing alkaline solution are continuously fed into a film evaporator 15 and concurrently subjected to a neutralization reaction and concentration/drying in reduced pressure while a film of a mixture of the acidic solution with the alkali solution is being formed on the inside wall of the evaporator. The obtained concentrated and dried surfactant has a low b value and an excellent hue because it undergoes little thermal deterioration during the neutralization.

Title: Image data compressor
Inventor: MUKAI HISAYUKI
IPC: H04N19/124
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To process huge amount of data by setting a quality factor based on a mean value, the standard deviation of a histogram and the shape pattern of a histogram distribution. SOLUTION: An electrical signal from a detector 2 is stored in a memory 8 of a data processing circuit 3. A histogram generator 9 analyzes a strength distribution of a received signal from the memory 8 to generate a histogram. A quality setting circuit 7 selects a variable 'quality' (x, y) the parameters of which are a mean value (x) and a standard deviation (y) of the histogram for generating a 'Quantum' (i, j, x, y). A discrete cosine transformer 4 transforms information from the memory 8 into frequency domain data DCT (i, j). A quantizer 5 quantizes the output information and the Quantum (i, j, x, y) to calculate new domain data DCT (i, j) and a new Quantum (i, j, x, y). An encoder 6 encodes a quantized data 'Quantized value' (i, j, x, y) and provides an output of the result.

Title: Anticorrosion permanent magnet and manufacture thereof
Inventor: KIKUI FUMIAKI
IPC: H01F1/053
Filed: 1992-12-10
Abstract: PURPOSE:To improve adhesion to a substrate and prevent the elution of the surface of a magnet, and to improve the corrosion resistance of the magnet by coating the surface of an Fe-B-Ra-based magnet having a specific composition with a tin oxide film by a thermal decomposition method using a solution of a tin alcoxide compound, and by further coating the surface of the magnet with an anticorrosion resin layer by electrodeposition. CONSTITUTION:An anticorrosion resin layer is created by electro-deposition on the surface of an Fe-B-Ra-based permanent magnet whose primary phase is a tetoragonal phase via a tin oxide film that contains C in the range of 100-1000ppm and has a thickness of not more than 500Angstrom . In this case, the adhesion strength of the tin oxide film drops when the thickness thereof exceeds 500Angstrom , and there is a possibility of peeling of the anticorrosion resin layer created on the surface of the tin oxide film. Hence, the thickness of the tin oxide film should be not more than 500Angstrom . When the amount of C is 100ppm, cracking occurs. When amount exceeds 1000ppm, insufficient thermal decomposition occurs. Thereby, it is possible to improve adhesion to a substrate and prevent the elution of the surface of a magnet, and to the corrosion resistance of the magnet.

Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To maintain quick response on a client side and to reduce the traffic and load on a server side by allowing a server computer to change distributing methods according to the number of information distribution requests from a client computer. SOLUTION: On the server computer 100, a request accepting process 111 when accepting an information distribution request from a client computer refers to a distribution switching table 122 and then requests a unicast file transfer process 113 to perform transmission when the flag of its information is OFF or a multicast file transfer process 114 to perform distribution when ON. The result obtained by totalizing requests for a certain time is held in a request quantity totalization table 121 and a request quantity prediction process 112 predicts the number of requests made in a next request totalization period by pieces of information according to the result. When the number of prediction requests exceeds a threshold, the flat of the information in the table 122 is set ON.

Title: Traction control method for vehicle
Inventor: KAWAMURA TAKANARI
IPC: B60W10/18
Filed: 1991-12-20
Abstract: PURPOSE:To prevent excessive traction due to wear of a tire, by setting a speed obtained through some increase in the select-high increased or decreased speed of a driven-wheel speed, as an increased or decreased speed of a false vehicle speed, and determining a false vehicle speed on the basis of such increased or decreased speed. CONSTITUTION:In a false vehicle-body speed calculation circuit 7, a value DELTAV1' is obtained by multiplying an increased speed amount DELTAV1 of the driven-wheel select-high speed during acceleration of a drive-wheel control speed or at the time when a drive wheel is in a condition of spin by a specified proportion [(100Xalpha) percent]. This value DELTAV1' is then added to an immediately preceding calculation control reference speed VVn to provide a false vehicle speed. By so doing, the difference in diameter between tires is made permissible up to the alpha percent. In response to signals from the false vehiclebody calculation circuit 7 and a mean speed calculation circuit 5, a control logic circuit 8 causes operation of an engine throttle actuator to decrease the engine output.

Abstract: PURPOSE: To eliminate laser interference fringes occurring on photosensitive material in the case of forming an image by exposure to a scanning laser by preventing reflected laser beams reflected respectively from the upper surface and the lower surface of a supporting body from being overlapped with each other on a photosensitive emulsion layer. CONSTITUTION: In a method for laser scanning and exposing the photographic sensitive material having the photosensitive emulsion layer at least on either side of the supporting body; an angle formed by the exposed surface of the photosensitive material with the scanning laser beam does not become a right angle in substance. It is desirable to set the angle of >=3 deg. and <=45 deg. as the angle nearest to the right angle in laser scanning; more desirably, >=5 deg. and <=25 deg.; much more desirably, >=7 deg. and <=20 deg.; and the most desirably, >=10 deg. and <=18 deg.. The interference fringe is caused by the interference of the laser beams respectively reflected on the upper surface and the lower surface of the supporting body, so that it is not caused by preventing two reflected laser beams from being overlapped with each other on the photosensitive emulsion layer.
