Title: Exhaust emission control device of internal combustion engine
Inventor: KATO KENJI
IPC: F02D41/04
Filed: 1994-01-25
Abstract: PURPOSE:To prevent NOx from being released in the atmosphere without being absorbed by the NOx absorbent by keeping the air fuel ratio unless the operational zone of the engine exceeds the second boundary line on the lower load side than the first boundary line when the operational zone of the engine exceeds the first boundary line and is shifted from the lean fuel zone to the rich fuel zone. CONSTITUTION:The operational zone of the engine is divided into the lean combustion zone on the lower load side and the rich combustion (or the stoichiometric air fue ratio) zone on the higher load side, and NOx is absorbed by the NOx absorbent 18 in the lean combustion while the NOx absorbed by the NOx absorbent 18 is released in the rich combustion. In this internal combustion engine 1, the air fuel ratio of the mixture is gradually controlled to be small when the operational zone of the engine is shifted from the lean combustion zone to the rich combustion zone. When the first boundary line is defined as the boundary line when the operational zone is shifted from the lean combustion zone to the rich combustion zone, while the second boundary line is defined as the boundary line when the operational zone is shifted in the opposite order, the second boundary line is set to the lower load side to the first boundary line.

Abstract: PURPOSE:To decrease the attenuation of a low frequency signal and to decrease the effect on a polar electronic component by providing a resistor generating a trigger voltage of a thyristor with a searching current fed to a center conductor of a cable in the same polarity as the normal feeding direction at cable location searching. CONSTITUTION:The searching current with the same polarity as the normal feeding current is given from the direction of the center conductor 1 of the cable at the location retrieval of a submarine cable and the current is increased until a current flows to a Zener diode 6 and a resistor 7 once. A voltage is generated across the resistor 7 by the current and fed to a gate of a thyristor 9 as a gate voltage to turn on the thyristor 9. When the thyristor 9 is turned on, a current flowing to a common amplifier 9 and the Zener diode 6 flows all to the thyristor 9 and the equivalent resistance is nearly the same as when being applied with the opposite polarity.

IPC: H01F6/00
Filed: 1985-01-21
Abstract: PURPOSE:To effectively operate a permanent current switch by connecting the end of a superconductive coil and the terminal near the center of the coil with a heater of the switch. CONSTITUTION:The heater wirings 41 of a permanent magnet switch 2 are connected with the end 7 or 71 of a superconductive coil 1, and a terminal 8 from the vicinity of the center of the coil 1. When thus connected, if the coil 1 is quenched to generate a resistance, a current is always flowed to the wirings 41 to be heated, and the switch is opened. Since the heater wirings are heated by a passive circuit, an external power source is not necessary, and the heater wirings are not heated due to the defect such as a power interruption or the erroneous operation of the power source.

Title: Radial tire for aircraft
Inventor: WATANABE ATSUSHI
IPC: B60C9/20
Filed: 1993-01-20
Abstract: PURPOSE:To attain weight reduction and suppress the generation of standing wave and uneven wear. CONSTITUTION:A strip body with plural cords is formed into zigzag shape to form an inner belt ply 41. Since there is no cut cord end at the belt ply end part, the quantity of rubber between the cords can be reduced without generating layer separation. Since the bent and overlapped parts of the cords at the ply end are generated continuously in the circumferential direction, the circumferential rigidity of the belt end part is enhanced, and the generation of standing wave is suppressed. The side wall part 24 side of a tread land part adjacently disposed inside of an outermost groove 54A is thinned, so that the ground pressure of the thinned part is lowered, and the tread land part on the side wall part 24 side is conversely heightened in adherence to the road surface. Dragging force caused by the belt of high rigidity is absorbed by the internal deformation of rubber, so that friction with the road surface is reduced to suppress the early wear of the grounding end part.

Abstract: PURPOSE:To reduce crosstalk between heads and to make a high speed transfer possible even when a track pitch is several mum by making a distance between recording tracks formed by plural closest magnetic gaps provided on the same multichannel magnetic head at least twice the track pitch. CONSTITUTION:By driving a magnetic tape 1 in the longitudinal direction 8 and rotating a rotary drum 3 provided inclined at a certain angle to the tape 1, magnetic heads 20 and 21 are obliquely travelled on the tape 1. At this time, electric current corresponding to a recording signal is conducted to the coils of the heads 20 and 21 and by magnetic field generated on magnetic gaps 13a to 13d, a signal is recorded on the tape 1. That is, recording loci A1 and B1 are formed by the gaps 13a and 13b and then, recording loci C1 and D1 are formed by the gaps 13c and 13d. Recording tracks A2 and B2 and C2 and D2 are formed likewise and recording patterns are formed on the tape 1. Thus, the distance between the tracks by the gaps is made at least twice as much as the pitch.
