Title: Infrared analyzer for gaseous ammonia
Inventor: KOTAKA MITSUO
IPC: G01N21/35
Filed: 1981-09-22
Abstract: PURPOSE:To prevent an interference by C2H4 and adsorption of NH3 to a catalyst and to analyze the NH3 in gas accurately, by providing a Pt powder catalyst converting the C2H4 in the gas to be measured into C2H6 by reacting the C2H4 with H2. CONSTITUTION:Plastic balls 3a-3c having a little smaller size than the inner diameter of a plastic ball vessel 1 and Pt catalyst powder are put in the cylindrical vessel 1, and filters 2a, 2b are pressed to introducing exit and entrance 7a, 7b parts by members 6a, 6b through O rings 5a, 5b using doughtnut-shaped flat members 8a, 8b, male screws 9a, 9b and nuts 10a, 10b. When gas to be measured and H2 are introduced from an introducing entrance 7b by using a cnverter for reducing C2H4 in the gas to be measured to C2H6 by H2, the catalyst is fluidized and the gas is mixed thoroughly. Then, the C2H4 is converted perfectly into the C2H6 because the catalyst 4 is activiated sufficiently at room temperature -500 deg.C and NH3 is determined accurately because the NH3 is not adsorbed. The catalyst 4 has a long life and is made do with a small quantity.

Abstract: PURPOSE:To correct curling due to heat at the time of fixing and increase the capacity of passing through a conveying passage by providing a roller which can form a sheet of record paper into a wave shape, in a conveying passage through which said sheet of record paper one side of which has been subjected to copying, is invertedly conveyed. CONSTITUTION:A sheet of record paper 3 one side of which was subjected to copying, is fixed by a fixing part 6, made flow down along a movable guide board 10, held in between a flat roller 61 on the upper course part of a conveying passage 13 and a pressure contact roller 64 on the circumferential surface of which annular projections 64a are arranged at a certain interval and, passing through the conveying passage 13, is housed into a stacker 26 by means of the rotation of the friction wheel 19 of a second paper feeding means 17. In this case, the sheet of paper 3 is formed into a wave shape to be made stiff while being held between the rollers 61, 64, thereby, improving a sending capacity through the conveying passage 13. A paper-feeding capacity at the time of refeeding and a separating capacity by means of the friction wheel 19 at the time of recopying, can also be improved.

Title: Lighting apparatus
Inventor: SATO RYODA
IPC: F21S2/00
Filed: 1990-06-08
Abstract: PURPOSE:To obtain a lighting apparatus having no flickering to be preferable for health of men and animals, growth of plants, etc., by supplying a three-phase AC to three fluorescent lamps by star wiring. CONSTITUTION:Straight fluorescent lamps 51, 52, 53 are disposed in parallel, heating bodies on the other side of the three fluorescent lamps are connected with each other, and terminals of a three-phase AC power source are connected with the heating bodies on one side, so a three-phase AC is applied to the three fluorescent bodies by star connection. The quantity of power at an instant is the total of instantaneous power quantities for the different phases, which is constant always, so flickering is eliminated completely, and a light source of a constant power like a sun light can be obtained. A light source which is preferable for eyes and health of men and animals, growth of plants, etc., can thus be obtained. Delta connection achieves a similar effect.

Title: Method and device for processing thermoplastic resin foam as well as cotton-like material
Inventor: MATSUZAKA SHIGERU
IPC: B29K105/26
Filed: 1994-06-09
Abstract: PURPOSE:To realize a effective recycling of thermoplastic resin foam by a method wherein cotton-like material having fine holes is obtained by centrifugally jetting thermoplastic resin foam heated under semi-molten state through slits or small holes. CONSTITUTION:Under the state that a rotative container 5 is rotatingly driven by a motor 9 and a rotative heater 19 is heated by being energized, thermoplastic resin foam cut or ground in the size from about several millimeters to several centimeters is charged through a stock-feeding opening 13 in the container 5. The changed thermoplastic resin foam is pressed against the inner peripheral surface part of the rotating heative 19 by the centrifugal force of the rotative container 5 so as to be heated by coming into contact with the heating wires of the rotative heater 19, resulting in turning the foam into semi-molten state in an instant and passing it through slits between the heating wires and jetting it outside from discharging holes 17 by centrifugal force. The thermoplastic resin foam under semi-molten state flys in a product receiving part to an outer peripheral side wall side by inertial force and, after being cooled and flowed by the cooling air generated with a rotating fan 39 so as to stretch it, resulting in being turned into cotton-like material having fine holes.

Title: Optical sensor
Inventor: MATSUNAMI TAKAO
IPC: G01J1/04
Filed: 1988-06-17
Abstract: PURPOSE:To reduce the incident angle dependency of the incident light quantity of the title optical sensor so that accurate light quantity measurement can be performed by providing a light intercepting or totally reflecting means to a condenser lens. CONSTITUTION:When the angle of incidence is 0 deg., most of light rays are intercepted by an intercepting section 9 and do not reach the light transmissive window 7 of a photodetector. When the angle of incidence is 45 deg., part of the light rays reaching the window 7 is intercepted. When the angle of incident is 90 deg., moreover, most of the light rays do not hit the section 9, but reach the window 7, because the light rays are largely refracted at the surface of a condenser lens 5 on the light source side. As a result, the detecting quantity of the light at a low angle of incidence decreases and that of the light at a high angle of incidence relatively increases. In other words, the difference in the detecting light quantity by the angle of incidence can be reduced and more accurate measurement can be performed.

Abstract: PURPOSE:To eliminate the retrieval mistake of a collation card by permitting a scanner to file the collation card in the file of an optical disk or a magnetic disk to scan the bar code of a carton and to retrieve the collation card so as to display/collate it. CONSTITUTION:The collation card 1 is prepared and the image scanner 4 reads the collation card 1. A display 6 stores having read information in the file 5 of the optical disk or the magnetic disk and a title is inputted by the display (personal computer) 6. Data of the collation card 1 and the file 5 are printed by a printer 7. A bar code label 8 is sealed on the carton 3 and the content is read by a bar code reader 9. The content of the collation card 1 stored in the file 5 is retrieved and displayed in the display 6. Thus, a collation worker can collate the card by a screen content displayed in the display 6 without retrieving the collation card 1 each time.

Title: Image forming device
Inventor: YANAGISAWA TAKAAKI
IPC: G03G15/00
Filed: 1990-06-08
Abstract: PURPOSE:To save the quantity of toner required for developing by limiting an image area formed on a recording medium to one part when test copying is instructed. CONSTITUTION:A photosensitive body 121, an electrostatic charge means 122, a destaticization means 123, an exposure means 110, a developing means 124, a transfer means 126 and a fixing means 12C are provided. Then, when the test copying is instructed by an input means 150, the electrostatic charged area of the electrostatic charge means 122 on the photosensitive body 121 is limited to a prescribed range by a control means. Due to that, even when exposure corresponding to an original is executed on the photosensitive body 121, an electrostatic latent image is formed only at an electrostatic charged part and an image formed on the recording medium becomes the image of an area corresponding to the electrostatic charged area. Thus, the quantity of the toner consumed at the time of test printing is suppressed.
