Title: Exhaust gas purifying device
Inventor: ISHII MASARU
IPC: B01J23/40
Filed: 1995-01-27
Abstract: PURPOSE: To provide a device by which NOx in an exhaust gas discharged when the fuel-air ratio is deviated to the lean side can particularly efficiently be removed. CONSTITUTION: In this device, a lean NOx catalyst (B) obtained by depositing a catalytic noble metal and an NOx occlusion material on a porous carrier is disposed on the upstream side of an exhaust gas passage and a three dimensional catalyst (A) obtained by depositing a catalytic noble metal on a porous carrier is disposed on the downstream side of the exhaust gas passage. NO in the exhaust gas is allowed to react with a large amount of oxygen in the exhaust gas on the lean NOx catalyst (B) on the upstream side of the exhaust gas passage to convert NO into NO2 , which is then occluded in the NOx occlusion material. At this time, the larger the amount of oxygen, the more easily the oxidation reaction of NO is effected and even when the fuel-air ratio is greatly deviated to the lean side in a transition region, the reaction is satisfactorily effected.  When the fuel-air ratio is on the rich side, NOx occluded in the NOx occlusion material is released, and then, reduced and removed not only on the lean NOx catalyst (B) but also on the three dimensional catalyst (A).

Title: Numerical controller
Inventor: KASHIHARA KEIZO
IPC: G05B19/4155
Filed: 1992-01-27
Abstract: PURPOSE:To exactly judge a state signal by repeatedly judging the establishment of a prescribed condition until the condition is established in a timing in the same or shorter interval as or than the interruption interval of the input and output of a main body by a firmware corresponding to a macrocommand. CONSTITUTION:At the time of activating the operation of the working program of an RAM 4 from a control disc 7, the analyzing means of an ROM 3 successively reads the working program, analyzes it, and executes a working. At the time of the processing of a prescribed macro-execution command, the working program calls a queuing processing being the condition judging function of the firmware of the ROM3 (or RAM 4) corresponding to the command. In the queuing processing, the judgment of the set prescribed condition is repeatedly operated until the condition is established, in the timing in the substantially same or shorter interval as or than the interruption interval of an I/O 8 of the main body. Thus the processing time can be set in the timing faster than the off/on/off of the state signal by the firmware, and the judgement can be stabilized.

Filed: 1991-01-10
Abstract: PURPOSE: To obtain essentially round composite ring by forcing a round composite ring which is not true round onto a mandrel and heating the ring together with the mandrel to the relaxation temp. of the matrix. CONSTITUTION: The composite ring 10 is forced onto an essentially round solid mandrel 12 which has a higher thermal expansion coefficient than that of the ring 10, and then heated to a temp. higher than the stress relaxation temp. of the matrix alloy. The mandrel 12 expands with a higher expansion rate than that of the composite ring 10 and the mandrel enlarges the inside diameter of the composite ring 10. Thereby, the inside diameter of the ring 10 is kept in essentially true round structure within 0.003 inch., and on the other hand, the internal stress of the composite matrix alloy can be relaxed by the heat treatment.

Abstract: PURPOSE:To obtain a circuit which can be easily set and is not disturbed by noise by providing an optical fiber cable between the transmitter and receiver sides of a fluid together with a light emitting element and a photodetecting element set at both sides of said cable and storing the middle part of the cable into a pipeline. CONSTITUTION:A part of an optical fiber cable 22 is stored into a pipeline 1 set between the feed and receiver sides of a fluid, e.g., between an outdoor gas meter 2 and an indoor gas tool 5. Both terminals of the cable 22 are drawn out of the line 1. An optical signal is supplied to a terminal 22a at one side from a light emitting element (not shown in the figure) which is set opposite to a gas alarm 6 and emits light when the leakage of gas is detected. While a terminal 22b at the other side applies an optical signal to a drive part 15 which is actuated by the output of a photodetector (not shown in the figure). With application of the optical signal, the part 15 closes a cut-off valve 3 to stop the supply of gas. This simplifies the setting of transmission lines and also prevents a malfunction due to a floating electric field.
