Title: Exhaust emission control device of internal combustion engine
Inventor: ISHIZUKA YASUJI
IPC: F01N13/02
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To restrain exhaust of HC and CO while efficiently purifying NOx by controlling the air-fuel mixture air-fuel ratio by making a feedback process to reverse the downstream side exhaust air-fuel ratio of an NOx absorbing catalyst to rich just after the target air-fuel ratio of an air-fuel mixture is switched to the theoretical air-fuel ratio or rich from lean. SOLUTION: Air-fuel ratio sensors 10 and 11 are respectively arranged on the upstream-downstream sides of an NOx absorbing catalyst 5 of an exhaust system, and just after the target air-fuel ratio of an air-fuel mixture is switched to the theroretial air-fuel ratio or rich from lean, by an ECU 6, air-fuel ratio feedback control is performed by using the downstream side sensor 11 instead of the upstream side sensor 10. At this time, since reversal to rich of the downstream side sensor 11 delays by removal of NOx and O2 in the catalyst 5, even if the exhaust air-fuel ratio detected by the upstream side sensor 10 reverses to rich, a fuel injection quantity is controlled so as to be gradually increased until the downstream side sensor 11 reverses to rich further, and reversal to rich of the downstream side sensor 11 is quickened.

Title: Magnetic recording medium
Inventor: TAKASUGI YASUSHI
IPC: C09D127/06
Filed: 1988-06-21
Abstract: PURPOSE:To increase residual magnetic flux density and to improve high-temp. stability by using a copolymer consisting of vinyl chloride, alkyl vinyl ester carboxylate, etc., as a compd. having an epoxy group, etc., as a binder resin component and fixing the binder resin in which magnetic powder is dispersed on a base. CONSTITUTION:This recording medium consists of the base and the magnetic layer applied on the surface thereof. The copolymer consisting of the vinyl chloride, the alkyl vinyl ester carboxylate, the other monomer copolymerizable with the vinyl chloride, and the saponified matter of the alkyl vinyl ester carboxylate as the respective constituting components, a compd. having epoxide, and polyisocyanate are used as the binder resin components to be used for the magnetic layer and the dispersion prepd. by dispersing the magnetic powder into such resin components are dispersed is fixed on the base, by which the magnetic layer is formed. The high dispersibility of the magnetic powder into the binder resin is, therefore, assured. The high residual magnetic flux density is attained in this way and the high-temp. dechlorination of the vinyl chloride copolymer is effectively prevented by the presence of the epoxide.

Title: Carbon-quantity measuring apparatus
Inventor: SANAI YOICHI
IPC: G01N31/00
Filed: 1988-06-20
Abstract: PURPOSE:To improve the measuring accuracy of the reliability of a system by stopping the operation of the system according to the detected results of a pressure sensor which detects the pressure in a reactor and a temperature detecting means which detects the temperature in the reactor. CONSTITUTION:An operating switch is turned ON, and the driving of a specimen feeding pump 1, a reaction-liquid feeding pump 4B and a compressor pump 10 is started. The increase in temperature of a drum heater 12A is started. A thermocouple 12B judges whether the temperature of the reactor 12 reaches the optimum temperature or not when the specimen reacts with an oxidizing agent. When the temperature is not reached, whether a specified time has elapsed after the operation switch was turned ON or not is judged. When the time has not yet elapsed, a pressure sensor 11B judges whether the pressure in the reactor 12 exceeds a value which is obtained by adding a specified value to the operating pressure of a relief valve 11A or not. When the value is not exceeded, the relief valve 11A is not operated normally. The abnormality is displayed on a display part, and the measuring system is stopped.

Abstract: PROBLEM TO BE SOLVED: To facilitate the recovery of a ruptured head by providing a holding member such as a snap ring which has the shape protruding in the direction of inner radial direction by sufficient distance for the contact of the holding member of a bit on an inner peripheral face of a wear-resistant collar. SOLUTION: A cylindrical chuck 10 is connected to a drill string casing 14 by a screw 12. A shunk 20 which is engaged in such a manner that it is driven together with the chuck 10 and is elongated in the axial direction is provided in a drill bit 13. A soft holding member 50 which protrudes in the radial direction by sufficient distance for stopping a holding shoulder 32 when the shunk 20 is ruptured and a part of a bit head 26 drops downward in the axial direction is connected to an inner face 52 of a hollow, cylindrical, and wear-resistant collar 42 in such a manner that is can be attached and detached freely between the wear-resistant collar 42 and the bit head 26. It is recommended that the hold member 50 be a snap ring. Consequently, it is possible to hold the bit head 26 in the chuck 10 even if it leaves the shunk 20.  Accordingly, it is possible to recover the bit head even when the bit 3 is ruptured.

IPC: B01D1/26
Filed: 1977-12-19
Abstract: PURPOSE: To reduce salt water refining cost through an effective utilization of salt water fed by concentrating brackish water with less energy consumption in such a manner that a part of the brackish water withdrawn from the anode chamber is returned to the chamber after concentration.  
     CONSTITUTION: Brackish water withdrawn from an anode liquid circulation tank 4 undergoes dechlorination with a dechlorination column 6. Then, Na 2 SO 3  and NaOH are added thereto from lines 25 and 26 for controlling pH after the residual chlorine is removed as required. A part of the brackish water is blown down from a line 27 as required to prevent accumulation of Na 2 SO 4  or the like. The concentrated salt water down to a low temperature through a flash evaporation with flash evaporators 7 and 8 is heated with the steam generated from the evaporator 7 condensed by a condensor 9 and then, returned to a tank 4. If necessary, it is returned to the tank via a chelate resin column 11 after removal of multivalent  metal ion. The steam generated from the evaporator 8 is condensed away with a balometric condenser 10.

While the voltage VL is connected to the terminal 21 when the signal Y undergoes the A/D conversion as the voltage Vin. Then the input analog voltage is compared with each reference voltage via each voltage comparator 14 in a state where the prescribed DC bias voltage is applied. Based on these comparison results, the digital data on the binary number is outputted from a decoder circuit 15.

Abstract: PROBLEM TO BE SOLVED: To restrain the degradation of luminous flux, improve decomposition efficiency of dirt ingredients, in particular, fatty acids such as oils and fats and prevent the degradation and peeling of a photocatalyst film by providing a metal oxide layer that can decompose a fatty acid containing an erucic acid as a main ingredient at a certain rate on the surface of a bulb. SOLUTION: A metal oxide layer 6 containing fine particles of anatase-type titanium oxide as a main ingredient is formed on the outside surface of a bulb 2 as a photocatalyst film by means of spray, immersion or the like. The metal oxide layer 6 can decompose a fatty acid containing an erucic acid as a main ingredient at a rate not less than 30 μg/cm<2> per 50 hours of lighting. Therefore, it is preferable that the stuck quantity of the metal oxide layer 6 is 20 to 400 μg/cm<2> and it contains 5 to 18 wt.% of an inorganic binder. Thereby, high luminous flux retention rate as well as the decomposition function of the fatty acid can be maintained without causing the degradation or peeling of the metal oxide layer 6.
