Title: Exhaust emission control device for internal combustion engine
Inventor: TAKAMI AKIHIDE
IPC: B60W10/06
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To ensure the adsorption quantity of hydrocarbon by an adsorbing material even when an engine is on and off with high frequency by detecting the adsorption amount of hydrocarbon by an adsorbing material when an internal combustion engine is stopped, and heating the adsorbing material to a hydrocarbon releasing temperature when it is judged that the adsorbing amount is above a specific amount. SOLUTION: An HC adsorbing material 13 having an adsorption temperature zone for adsorbing HC (hydrocarbon) as one of the harmful component in an exhaust gas and a releasing temperature zone for releasing the same, and a three-way catalytic converter 14 are mounted in an exhaust gas path 12 in an engine 1 of a hybrid car. On this occasion, the adsorption amount of HC is estimated on the basis of the engine water temperature, the catalyst temperature, the engine stop period, the total intake air amount and the elapsed time after the start of engine by a general control (ECU) 100. When it is judged that the adsorption amount is above a predetermined amount as the result of the estimation, the adsorbed HC is released, and the operation of the engine 1 is extended until the three-way catalytic converter 14 reaches an active temperature.

Title: Method for controlling air-fuel ratio of internal combustion engine
Inventor: SHIBAGAKI NOBUYUKI
IPC: F02D41/22
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent the air-fuel ratio from being erroneously corrected when a driven device or a power transmission means is abnormal. SOLUTION: In a method for controlling the air-fuel ratio of an internal combustion engine, the elapsed time of the 30 deg. crank angle near the top dead center of compression and the elapsed time of the 30 deg. crank angle near 90 deg. after the top dead center of compression are found. The difference between the elapsed times of 720 deg. crank angles is found in relation to a first cylinder and a second cylinder in which combustion is to be performed next the first cylinder. The virtual elapsed time obtained when that torque fluctuation is not generated is assumed from the elapsed time difference between the first cylinder and the second cylinder is found, and the torque fluctuation amount is calculated by using the virtual elapsed time.  Whether a driven device 32 such as an accessory to be driven by a crankshaft 13 through a power transmission device 31 such as a belt or the power transmission device 31 is abnormal or not is judged from the torque fluctuation amount. When it is judged that the device is abnormal, correction of the air-fuel ratio, based on the torque fluctuation amount is prohibited.

Abstract: PURPOSE: To effectively reduce the amount of remaining monomers, solvents or the like by a method in which polymers containing the remaining monomers and solvents are first pretreated by heat and reduced pressure and then further treated by heat and reduced pressure after a specified amount of pressurized water is injected into them.  
     CONSTITUTION: Polymers or polymer blends containing remaining monomers, dimers, trimers and solvents are taken out of reactor 1 to be heated up to 200 to 270°C at preheater 2.

Abstract: PURPOSE:To obtain a device with a simple construction which automatically works in the vertical compensation for inclination in two directions orthogonal to each other, by suspending a double-side reflecting rectangular prism with two sets of hanging lines each crossing at an upper hanging point. CONSTITUTION:A double-side reflecting rectangular prism 2 in an optical system is mounted on a pendulum base 4 with the square edge thereof downward and the pendulum base 4 is suspended at upper hanging points 5 and 5' in such a manner that two sets of hanging lines 8 and 8' and 9 and 9' separate wider downward respectively. The sets of hanging lines parallel each other with the interval between the fulcrum points 6 and 6', and 6'' and 6''' of the pendulum body 4 equal to that between the upper hanging points 5 and 5' and the vertical length L thereof is set one half as much as the focal length of a condenser lens 1. Now when a body tilts by an angle theta in the direction X, a first reflection point 2' of the double-side reflection rectangular prism 2 is always on vertical optical axes V and V' while the pendulum is kept parallelogrammic and light from a light emitting source 3 is always emitted upward vertically via the condenser lens 1. When the body tilts in the direction Y, the first and second reflection surfaces of the pendulum base 4 are always kept horizontal and reflect a luminous flux incident vertically from the light emitting source 3 in the vertical way.

A carbon protective film 10 is formed on the granular film 3 as a magnetic layer in the vacuum chamber and a fluorinate type lubricating layer is laminated. The surface of the composite layer can be smoothened efficiently, without roughening the deposit-free region.

Abstract: PURPOSE:To attain high speed phase locking and to improve noise immunity by forming a sufficient in-phase state at the intermittent operating mode and providing a 1-bit data latch and a gate circuit to a data input section so as to synthesize a strobe signal. CONSTITUTION:A control circuit 9 receiving an output of a phase comparator 3 and an intermittent control signal in the intermittent operation controls gate circuits 10, 11 controlling the input of a reference frequency divider 2 and a variable frequency divider 5 by a time for a phase error so as to make two inputs to the phase comparator 3 in phase. Moreover, the control circuit 9 forms a loop control signal shorter than the leading of the intermittent control signal by a prescribed time. A loop switch 8 is controlled directly by the loop control signal. The phase adjustment is applied at the start of the intermittent control by the operation so as to make the operation enough to be in a short locking time and the conventional mode of the frequency synthesizer is reached.

Filed: 1993-07-27
Abstract: PURPOSE:To prevent the transmission from being affected from an echo and group delay distortion caused in a data transmission line path by using plural carriers for the transmission of data information through data transmission and data reception frequency bands. CONSTITUTION:Transmission data are inputted from a data interface section 100 and a timing generating section 500 inputs a 4-bit parallel signal to each of modulation sections 300-347 according to a predetermined clock. Let a phase modulation speed in the modulation sections 300-347 be 25 baud, data from the interface section 100 are received by using a clock in the unit of 1/25s for data communication in 4800BPS. Similarly a generating section 200 generates a carrier modulated by the 25 baud 4-phase bias system as a pilot signal. A pilot tone and 48 kinds of carriers phase-modulated by the modulation sections 300-347 are synthesized by a synthesis section 400 and the result is sent via an interface section 600.

Abstract: PURPOSE:To obtain a high functional group content liquid diene copolymer suitable for tires in high yields and good reaction controlability, by polymerizing a conjugated diene and an active hydrogen group-containing, ethylenically unsaturated monomer by using a functional free-radical initiator. CONSTITUTION:Preparations are made for a functional free-radical initiator comprising a peroxide compound such as hydrogen peroxide or t-butyl hydroperoxide or an azo compound such as 4,4'-azobis(4-cyanopentanol).

Abstract: PURPOSE:To exhibit firm locking force by pressing a part of the end part of a second metal plate into apertures in a state where the part is sandwiched between the apertures and the cut-up pieces formed on the first metal plate, so as to be press formed with cut-up pieces. CONSTITUTION:A plurality of joint parts 13 are formed between a first metal plate and a second metal plate 12, and cut-up pieces 14 are so formed as to have apertures 15 on the first metal plate 11. No preliminary processing is applied on the second metal plate 12 and a part of its end edge is pressed in apertures 15 in such a state as sandwiched between the apertures 15 and the cut-up pieces 14 of the first metal plate 11 so as to be press processed with the cut-up pieces 14. The press-in part of the second metal plate 12 is firmly connected to the rest part via a connection part so as not to be separated. Because the cut parts of the second metal plate 12 abut on aperture edges 15a, 15b of the first metal plate 11 by abutting, its locking force is large. The firm locking force can be thus exhibited.
