Title: Production of hydrogen peroxide
Inventor: IWANAGA SEIJI
IPC: C01B15/029
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To obtain hydrogen peroxide advantageouly in an industrial operation avoiding the risk of explosion in with and requiring the of a high pressure by reacting oxygen with hydrogen in a supercritical fluid containing a catalyst in the production of hydrogen peroxide from oxygen and hydrogen. SOLUTION: This method is carried out by reacting oxygen with hydrogen in a supercritical fluid containing a catalyst. The supercritical fluid is a liquid having a higher pressure than the critical pressure and a higher temperature than the critical temperature, and the critical temperature is preferable to be -20-100 deg.C. As a result, it is possible to react at a preferable temperature in the production of hydrogen peroxide. Although the critical pressure is not particularly limited, a pressure of less than 300atm is preferable from an industrial and economical point of view. As the most preferable supercritical fluid, the supercritical fluid of carbon dioxide is illustrated. It is preferable that the pressure of the reactant is 73-300atm and its temperature is 31-100 deg.C. A substance having a metal belonging to groups 9, 10 and/or 11 is illustrated as the catalyst.

IPC: F02B77/13
Filed: 1995-03-03
Abstract: PURPOSE: To obtain a surrounded type engine which is improved in soundproofness and maintenance performance. CONSTITUTION: An engine is arranged inside an inner case 22. An inner opening 33 is formed on a right side wall of the inner case 22. An outer opening 34 is formed on an outer case side wall on the side of the inner opening 33. An inner lid plate 35 for covering the inner opening 33 is parallely connected to an outer lid plate 36 for covering the outer opening 34 by means of a coil spring. The inner lid plate 35 is brought into close contact with the inner opening 33 of the inner case 22 by negative pressure which is generated inside the inner case 22 during operation of the engine. With such a setup, soundproofness is improved since the engine is doubly surrounded by means of the inner case 22 and the outer case 23. Maintenance performance is also improved since the outer lid plate 35 and the inner lid plate 35 are simultaneously attached and detached.

Filed: 1988-02-29
Abstract: PURPOSE:To control the operation of a movable poppet for supplying coolant and to optimize the supply of coolant suitable to conditions of rolling by controlling and fluctuating compressed air pressure supplied to a control valve through a pilot circuit. CONSTITUTION:Compressed air is made up to be supplied to an entrance port 23 of a spray control valve 20 through the pilot circuit 12.

Title: Ciphering circuit
Inventor: TORII NAOYA
IPC: H04L9/22
Filed: 1994-03-15
Abstract: PURPOSE:To improve the safety and the processing speed by providing the constitution in which a key data storage means, that beforehand stores key data, can not be directly accessed from the external. CONSTITUTION:In a conventional ciphering circuit constitution, a key register is replaced by a key address register 8 and a key memory control circuit 9 and a key memory 10 are added. In order to prevent the deterioration of the safety by an external key input, a ciphering key is beforehand stored in the memory 10. When a key address is inputted from an external, a key corresponding to the inputted key address is taken out from the memory 10 by the circuit 9 and the key is set in the register 8. Thus, the memory 10 can not be accessed from an external controller 2. Therefore, the controller 2 sets a key without referring to the key.

Title: Carbonate-containing uranium solution concentrating method
Inventor: YOKOTA KENJI
IPC: C01G43/00
Filed: 1979-04-12
Abstract: PURPOSE: To efficiently recover carbonate and uranium from a dil.soln. of carbonate-contg. uranium collected from sea water by contacting the soln. to an acidic cation exchange resin to remove carbonate radicals and contacting it to an acidic cation exchange resin again.  
     CONSTITUTION: A dil. soln. of carbonate-contg. uranium after desorbing an adsorbent with uranium adsorbed from sea water is upward counter-currently contacted to a cation exchange resin of weakly acidic type or the like to remove carbonic acid radicals as carbon dioxide. By this countercurrent contact in the primary process a uranium desorption loss is prevented. The radicals-free soln. is contacted to a cation exchange resin again to allow the uranium to be selectively adsorbed. Since this resin slightly adsorbs org. matter in the soln., the conc. uranium soln. contains no org. matter to facilitate after-treatment.

Title: Distributed capacitor forming structure in base plate mounting and serial resonance circuit
Inventor: ENOHARA KAZUO
IPC: H03H5/00
Filed: 1995-02-10
Abstract: PURPOSE: To facilitate and adjustment of the capacitance by adopting a distributed capacitor comprising a distributed constant for a capacitor of an electronic circuit such as a series resonance circuit and making a hole in a base plate in the vicinity of the distributed constant capacitor so as to avoid dispersion in the capacitance of the distributed capacitor. CONSTITUTION: A hole surrounding one terminal of a coil L is made in a base plate in the vicinity of the one terminal of the coil L. Since the base plate has a larger dielectric constant than that of air, the hole is made to remove the base plate in existence between the coil L and a copper foil provided to the lower side of the base plate and connecting to ground. Thus, the capacitance of a distributed capacitor in existence between the coil L and the copper foil forming a ground plane and connecting to ground is reduced. Furthermore, a conductor 1 is provided and its both ends are connected to the copper foil on the rear side of the base plate and to ground. The distance between the conductor 1 and the coil L is changed by tilting the conductor 1 with respect to the base plate.  The capacitance of the distributed constant capacitor C3 comprising the distributed circuit constant is the sum of the distributed capacitance between the coil L and the conductor 1 and the distributed capacitance between the coil L and the copper foil on the base plate. The distance between the coil L and the conductor 1 is changed by tilting the conductor 1 with respect to the base plate to change the capacitance of the capacitor C3 .

Title: Picture recognizer with error correcting function
Inventor: TSUNEKAWA TAKASHI
IPC: G06V10/98
Filed: 1982-03-24
Abstract: PURPOSE:To have an automatic error correction or rejection, by giving a 2- dimensional inspection to each symbol in vertical and horizontal directions on the basis of a connection rule for adjacent positions of symbols. CONSTITUTION:A memory 3 contains three sheets of memories 111, 112 and 113 to store the 1st, 2nd and 3rd symbol codes after arranging the results of recognition of unit picture elements in order of larger resemblance. The memory 111 forms an initial picture by burying the symbol of the 1st resemblance into each picture element. For each picture element in the initial picture, a penalty calculating circuit 15 checks the connection with symbols in vertical and horizontal directions with reference to a table 12 and stores the number of picture elements incapable of connection in a memory 16 in the form of penalties. The replacement of symbols is repeated for a penalty picture in which penalties are arrayed in a 2-dimentional form. Thus an error is corrected.
