Title: Method and apparatus for decomposing nitric acid
Inventor: ABE TOSHIHIRO
IPC: C02F1/04
Filed: 1995-05-22
Abstract: PURPOSE: To decompose nitric acid of relatively high concentration into harmless water by using an economical, safe method and apparatus by decomposing nitric acid in mixed gas into nitrogen oxides by the use of a catalyst and reducing the nitrogen oxides into nitrogen and water using ammonia as a reducing agent. CONSTITUTION: A waste nitric acid aqueous solution is introduced from an injection pump 1 into a nitric acid gasification unit 4 while being adjusted to keep the level of the gasification unit 4 constant by a level control valve 2 interlocked with a level gauge 3. The gasified nitric acid, with entrainments separated by a flow straightener 10, is sucked from a pump 21 while being adjusted by a flow rate meter 20 and heated with part of air which passed through a heat exchanger 17 by a burner 12. The heated gasified nitric acid is decomposed into NOX by a nitric acid decomposition reactor 13 filled with a nitric acid decomposition catalyst 14.  Gas from the reactor 13, with the amount of part of air which passed through the heat exchanger 17 adjusted by a carrier gas control valve 18, is controlled to temperature necessary for the reduction and reduced by the reaction with NH3 in a reduction reactor 18 into harmless N2 and H2 O.

Filed: 1988-05-20
Abstract: PURPOSE:To maintain the speed of a wrist portion end constant while changing smoothly the position of the wrist portion by dividing an amount of angular change in the wrist portion accompanying the movement between instruction points with dividing number smaller than the dividing number of transfer locus of the wrist portion end between the instruction points for interpolation control and specifying control frequency needed between acceleration and deceleration areas in such change. CONSTITUTION:On the basis of data from an instruction data input section 3 is divided the transfer locus of a torch end between the instruction points with a predetermined dividing number according to the instruction speed in a dividing means 4, while the angular change amount of a welding torch accompanying the movement between the instructions is divided by a dividing means 5 with a dividing number smaller than said dividing number for interpolation control on the basis of the dividing points divided by a calculating section 7. At the same time in a setting means 6, control frequency needed between acceleration and deceleration areas in the angular change of a welding torch is set more than that needed between the acceleration and deceleration areas in the transfer of the torch end so that the positional change of the welding torch is carried out smoothly maintaining the speed constant.

Abstract: PURPOSE:To obtain the fixing anchor very effective to prevent fall-down of the automatic vending machine by imbedding a fixing anchor, injecting a mortal in an inner and an outer circumferential faces of the anchor to fix the anchor to ground and connecting the automatic vending machine to the anchor. CONSTITUTION:A fixing anchor 1 is made of a hollow pipe member and openings 6, 7 are provided in a lower end and an upper part, and then when the fixing anchor 1 is embedded in a hole to which a cement is applied, the comment is allowed to flow to come into contact with the inner and outer circumferential faces of the anchor and then the contact area between the anchor and the cement is increased to increase a fixing strength of the anchor. Since a swollen part 4 of the anchor is formed in at least its upper part, when the anchor is embedded in a hole formed on ground, the swollen parts 4, 5 come into contact with the inner face of the hole to prevent inclination. Furthermore, since the swollen parts 4, 5 act like a resistance against coming out, the anchor is fixed strongly to the hole formed on ground. Thus, the fixing anchor 1 very effective to prevent fall-down of the automatic vending machine is obtained.

Title: Lubricative supporting device for outer pin of rotation converting mechanism
Inventor: MINEGISHI SEIJI
IPC: F16H1/32
Filed: 1982-07-16
Abstract: PURPOSE:To have sufficient lubrication between trochoidal cogs and pin, in a rotation converting mechanism in which the inner gear consists of a pin in the circular cog shape and the outer gear is in trochoidal cog shape, by furnishing an oil groove for lubrication between the pin and casing. CONSTITUTION:When an eccentric member 6 formed as in a single piece with the input shaft 1 rotates, the external gear 11 orbits (swings) with rollers 10 interposed while the roller holes 13 excavated in this external gear 11 are circumscribed with the inner rollers 14. Because eccentric rotation of the eccentric member 6 is absorbed in the inner roller holes 13, which is each larger than the diameter of the inner roller 14 by an amount corresponding to twice (2e) the eccentricity e of the eccentric member 6, the external gear 11 does not make rotation round its own axis but makes only orbiting (swinging rotation), and this orbiting causes rotation of the internal gear 19, which is equipped with pins 20 meshing with the external gear 11. The internal gear 19 which functions also as rotary casing is equipped with oil grooves 24A, 24B in order to lubricate the meshing parts between the trochoidal cogs 12 of external gear 11 and the pins 20 of internal gear 19.

Filed: 1980-09-05
Abstract: PURPOSE:To make easy the adjustment of frequency compensation amount and to obtain a low cost oscillator, by providing a means in which the bias for variable reactance coupled wit a solid-state oscillating element is changed with ambient temperature change. CONSTITUTION:A gun diode 7 is located at about 1/2 intube wavelength from a short-circuit plane 11 of a cavity resonator 10, and a varactor diode 1 is added in the resonator with a suitable coupling. A parallel circuit consisting of a thermister 2 and a resistor 3 is connected between a power supply 6 and the diode 1 to give reverse bias to the diode 1, and a resistor 4 connected in parallel with the diode 1 is connected to a power supply 5. The resistance value of the thermister 2 is decreased when ambient temperature rises, the bias voltage to the diode 1 is increased, the junction capacitance of the diode 1 is decreased and the oscillating frequency is made higher. Since the temperature coefficient of a gun diode oscillator 7 is negative, the change in the resonance frequency can be compensated by the change in the capacitance of the diode 1. The amount of frequency versus temperature compensation can be adjusted easily.
