Title: Preparation of amino acid polymer
Inventor: DEEBUITSUDO ERIOTSUTO AADORAA
IPC: C08G69/44
Filed: 1994-09-21
Abstract: PURPOSE: To obtain an amino acid polymer which is useful for cleaning and detergent additives, fertilizer and pesticide additives, personal care product additives, etc., by preparing a reaction mixture of an amino acid, an acid catalyst, and a polyfunctional monomer, adding a process aid to the mixture and/or subjecting it to mechanical treatment, and heating it to remove water.  
     CONSTITUTION: A reaction mixture comprising 15-95 wt.% amino acid, 3-85 wt.% acid catalyst (pref. an oxo-acid contg. phosphorus and sulfur or an org. or inorg. salt contg. acidic hydrogen), and 0-50 wt.% polyfunctional monomer is prepd. The mixture is made perfect by the addition of a process aid (pref. zeolite, a sulfate, a carbonate, a perchlorate, a silicate, a chloride, a bromide, alumina, clay, glass beads, an amino acid polymer, or a granular polymer) and/or by using a mechanical means. The mixture is then heated to 110-300°C and is freed of water, and the resultant objective amino acid polymer is recovered.

Title: Desalter and drinking water producing device
Inventor: ISHIMOTO RYUTARO
IPC: C02F1/14
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To simplify the device and control to save energy and to desalt brine into clear water by providing a dew-condensation part formed by bending a light-transmissive synthetic resin plate, a water collector formed into a trough by bending both lower ends of the dew-condensation part and a raw water tank connected to the collector. SOLUTION: When the raw water is desalted, a desalter 1 is set at a place exposed to sunlight E with the inclined-face side of a dew-condensation part 2 directed toward the sunlight E, and the raw water 5 is injected into a raw water tank 5 from a water pipe 14, etc. Consequently, the raw water 5 is exposed to the sunlight E, heated and evaporated, and the humidity of an upper space is increased. Since the dew-condensation part 2 is cooled by the outside air at this time, the vapor is condensed on the inner face of the dew- condensation part 2 to form a waterdrop 7. The waterdrop 7 is moved along the inner face of the dew-condensation part 2, dropped and collected in a water receiving part 3. As the waterdrop 7 is distilled water of the raw water 5, clear water free of salt, inorg. matter, etc., is obtained.  Subsequently, the clear fresh water is drawn off from a discharge pipe 9 and appropriately used.

Abstract: PURPOSE:To prevent density unevenness of an image due to interference effect by forming a blocking layer made of a-Si, a photoconductive layer, and a surface coating layer contg. a specified element in a specified concn. distribution on a conductive substrate in succession. CONSTITUTION:The blocking layer 3 made of a-Si, the photoconductive layer 4, and the surface coating layer 5 contg. at least one of C, N, and O in a concn. distribution continuously changing from the layer 4 to the surface in at least one position are laminated on the conductive substrate 2 in succession to form a photoconductive material 1.

IPC: H05B41/16
Filed: 1991-09-30
Abstract: PURPOSE:To provide a discharge lamp lighting device which does not cause excess loads on an inverter circuit even after one discharge lamp has started lighting. CONSTITUTION:The DC output of a DC power source E is oscillated at an oscillation circuit 12 via switching elements Q1, Q2 and a driving circuit to induce high frequency alternating currents and to light up discharge lamps FL1, FL2. The voltage of a condensor C1 is used to allow a lamp voltage to be detected by a lamp voltage detection circuit 15.

Title: Automatic correcting method for form conveyance deviation on scanner device
Inventor: NAGATSUKA HIROBUMI
IPC: H04N1/04
Filed: 1988-10-05
Abstract: PURPOSE:To correct conveyance deviation characteristic to the scanner device automatically by calculating the deviation characteristic to the device as the inclination of a form previously and shifting image data stored in an image memory in practical use according to the inclination. CONSTITUTION:The conveyance deviation characteristic to the device is calculated previously as the inclination of the form from the image data which is stored in the image memory by scanning a test form previously. Then a specific form is scanned to calculate a shift quantity based upon the address on the image memory corresponding to a specific position on the form as an origin from the image data stored on the image memory according to the inclination, thereby shifting each image data by the shift quantity. Consequently, the data whose deviation is corrected is usable at a stage of character and pattern recognition to reduce the probability of an error and a failure in decoding. Further, the deviation is accurately corrected by using the mean value of deviation obtained by scanning plural test forms.
