Abstract: A compound of the formula: ##STR1## wherein R.sup.1 is a hydrogen atom or a methyl group, R.sup.2 is a hydrogen atom or a negative charge, X is a group of --N(R.sup.3)R.sup.4 (wherein R.sup.3 is a lower alkyl group, and R.sup.4 is a hydrogen atom or a lower alkyl group) or a group of --N.sup.+ (R.sup.5)(R.sup.6)R.sup.7 (wherein each of R.sup.5, R.sup.6 and R.sup.7 which may be the same or different, is a lower alkyl group), and n is an integer of from 2 to 4; or a pharmaceutically acceptable salt or ester thereof.

Abstract: A mounting object comprises a combination of a body wherein elements of a metallic heat-resistant two-dimensional fastener in a mounting surface, and their engaging portions projecting therefrom have their base portions embedded and integrally molded, and a mating base object wherein integrally molded mating fastener elements project for detachable engagement with said fastener elements. The mounting object body is formed as a heat-resistant material integral with a metallic two-dimensional fastener by covering and fixing part of the fastener elements of the metallic two-dimensional fastener with a carbon powder having a high melting temperature and covering bases thereof with a metallic powder, a ceramics powder, or a mixture thereof which is molded and sintered.

Abstract: A plurality of eccentric rotors are rotatably fitted between a fixed base and an output shaft on which an object to be vibrationproofed is mounted, the output shaft being supported movably in 3 to 6 Degree-of-Freedom, magnet spring mechanisms are provided on fitted wall surfaces between the fixed base and the eccentric rotor, a composite vibrationproof adjusting spring is provided between the fixed base and the output shaft, the magnet spring mechanism responding to a fine displacement of the output shaft, and in a case where the output shaft is greatly displaced, the output shaft is braked so as to be restored to a predetermined position by the composite vibrationproof adjusting spring mechanism. The magnet spring mechanism produces a large braking force since a rotational angle is large and a rotational-angle speed is high due to eccentricity of eccentric rotors.

Abstract: A system wherein raw material excavated from a plurality of pit faces on a mine are conveyed to and collected at a specific collecting location at the foot of a mountain by a plurality of vehicles and the degree of quality of collected raw material is then properly controlled at the specific collecting location is generally called a mining site control process. To practically execute such a mining control process, the degree of quality of conveyed raw material previously analyzed per each pit face and a quantity of conveyance thereof are confirmed at every time when the raw material is conveyed to the collecting location.

Abstract: Bit map memories, which have addresses corresponding to orderly-arranged red, green and blue dots of a color display panel, are provided corresponding to red, green and blue colors, respectively, and a color array memory is provided which has prestored data indicating the array of the colors of the dots in at least one dot area of the color display panel. Bit map data are simultaneously read out of the three bit map memories in the order of arrangement of the dots of the color display panel, and the bit map data thus read out are input into a color selector. In synchronization with this data readout color array data is read out of the color array memory. The color array data thus read out is used to control the color selector to output therefrom, as a color display control signal, the bit map data of a specified color.

Abstract: A docking and active damping device for space structures is provided, in a docking portion of one space structure to be docked, with a positioning device in which an output rotor can be moved and rotated within a two-dimensional plane by a composite rotation of one or more eccentric rotors capable of being independently driven and controlled by a direct drive motor and the output rotor, and a docking member having a docking ring and a latch mechanism are supported on the output rotor of the positioning device. A probe having a capture device capable of being protruded and driven in an axial direction by a linear motion is provided inwardly of the docking member, and the probe provides a 4-freedom movement according to a position of the passive side to capture and dock a drogue.

Abstract: Equipment for dissolving polyacrylamide powder to obtain an aqueous solution thereof for enhanced oil recovery comprisesfirst and second powder storage tanks for storing polyacrylamide powder under nitrogen atmosphere;a gas conveyor unit for carrying the polyacrylamide powder from the first storage tank to the second storage tank by nitrogen gas flow;a constant powder supply unit for receiving the polyacrylamide powder from the second storage tank, metering the powder, and sending the metered powder toa powder dispersion unit for dispersing in water the polyacrylamide powder.A first liquid supply unit sends the dispersion or solution of polyacrylamide powder obtained from the powder dispersion unit to a dissolution tank for completing dissolution of the polyacrylamide;and a second liquid supply unit transfers the polyacrylamide solution from the dissolution tank to a solution storage tank for storing the polyacrylamide solution.

Abstract: In a distance measuring equipment for measuring the distance between an interrogator and a transponder with high precision by detecting the time from transmission of an interrogation pulse from the interrogator to reception of a reply pulse transmitted from the transponder on the basis of timing positions of said respective pulses; as leading edges of the interrogation pulse and reply pulse, a waveform represented by the formula of: ##EQU1## where E and F represent finite positive values and T represents time, is used, or else as a leading edge of the interrogation pulse, a waveform which can be approximated by the above formula is used, while as a leading edge of the reply pulse, a waveform obtained by passing a waveform approximately expressed by the formula of: ##EQU2## through a low-pass filter having a predetermined cut-off frequency, is used.

Abstract: The reduction of nitrogen oxides involves the passage of gases containing nitrogen oxides at higher than 500.degree. C. over a catalyst comprising cerium oxide and nickel oxide in the CeO.sub.2 /NiO molar ratio of about 0.05 : 1 to 2.5 : 1 and when desired an addition thereto of rhodium in an amount of from about 7.5 to 25 parts by weight per 100 parts by weight of the nickel oxide and cerium oxide composition and when desired an addition to said nickel oxide and cerium oxide composition of ruthenium in an amount of about 10 to 50 parts by weight or an addition to said composition containing rhodium of ruthenium in an amount of about 15 to 50 parts by weight per 100 parts by weight of the nickel oxide and cerium oxide composition. Also, when desired, an addition to said composition of one or more metal sulfides and an addition to said composition of one or more metal oxides is utilized.
