Filed: 1982-09-10
Abstract: PURPOSE:To prevent shift to lean air-fuel ratio controlled, by driving an exhaust system air-fuel ratio controlling actuator after the lapse of a prescribed delay time, if the exhaust air-fuel ratio is judged rich. CONSTITUTION:When the output of an oxygen concentration sensor 18 which is arranged in the downstream part of an exhaust manifold and detects the exhaust air-fuel ratio from the residual oxygen concentration in exhaust gas varies, with a fixed comparison voltage as center, the actuator driving current I is set 0 until a prescribed delay time T is lapsed, in the case when rich is judged according to the result or rich-lean judgement in a fixed comparator 32 in accordance with output, and after the lapse of the pescribed dealy time T, the actuator driving current is increased with the rich-side integration constant of a rich-side integration circuit 36, and secondary air is supplied. Therefore, the secondary- air feeding time is reduced, and the secondary-air feeding amount is reduced, so also the controlled air-fuel ratio becomes close to the thoretical air-fuel ratio, and the exhaust-gas purifying performance is improved.

IPC: G01G13/06
Filed: 1985-07-18
Abstract: PURPOSE:To enable the constant maintenance of the discharging weight per unit hour by controlling the discharging weight at the time when discharging with feeding to a measuring hopper by the mean value of the control signal at the time when controlling the discharging weight per unit hour. CONSTITUTION:The commudity discharging weight per unit hour discharged from a feeder 22 is kept in a fixed value with the operation of an adjustment meter 26 when the commodity whose weight is the upper limit value WH is stored in a measuring hopper 16. In parallel thereto a mean value computing element 32 calculates the mean value of the output of the adjustment meter 26 and it is stored in a memory 44. The adjustment meter 26 is stopped then when the commodity weight inside the hopper 16 reaches the lower limit value WL. Also when the feed of commodity is started to the hopper 16 from the feeder 4, the output of an AND gate 55 becomes '1', the mean value is read out of the memory 44 and fed to a feeder controller 28. The discharging weight from the feeder 22 is thus controlled. When the digital measuring signal reaching to the upper limit value WH in due time the control by the adjustment meter 26 is performed again and the discharging weight per unit hour becomes constant.

Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent generation of friction and abrasion between a deflector wheel and a rope by providing rope groove forming parts of the deflector wheel in such a manner as to be freely rotated. SOLUTION: A deflector wheel 2 is so constructed that ring members 23 where one rope groove 21 is formed are inserted in a cylindrical core member 22 to be stacked, and a pressing plate 24 is fitted to both ends thereof to keep the ring members 23 from being slipped. The ring members 23 are respectively divided to be freely rotated. Oil, grease, a solid lubricant or the like is applied between the ring, members 23, and between the ring member 23 and the core member 22 to form a slip structure through a lubricant. Accordingly, if ropes different in tension are wrapped, the deflector wheel 2 can be freely rotated according to each tension. Accordingly, no friction and abrasion is caused between the rope and the deflector wheel 2 so as to lengthen the life of the rope.

Abstract: PROBLEM TO BE SOLVED: To improve the atomization efficiency of liquid in an external mixing method. SOLUTION: A gas discharge opening 20 formed in the peripheral part of a nozzle 12 has a contraction part 22 which is positioned upstream from the opening 20 and formed to be narrower than other parts and an expansion part 23 which is formed to be wider from the contraction part 22 toward an outlet. The speed of compressed air ejected from the opening 20 can be greater than the sound speed, and a large difference in speed is obtained between the compressed air ejected from the opening 20 and coating discharged from a liquid discharge opening 17 so that the atomization efficiency of the coating can be improved. Even in a region where the supply pressure of compressed air is low, the atomization efficiency of the coating can be improved as compared with a conventional method.  In an external mixing method in which liquid and compressed air are mixed outside a nozzle device, since both ends of the opening 17 and the opening 20 are set up to be on the same plane, atomized liquid is prevented from being scattered in droplets and from back-flowing.

Abstract: PURPOSE:To decrease generation of large water drops as well as effectively utilize leaking steam by a method wherein slits are formed on a side face of a hollow-structured stationary blade while a steam blowout hole is provided on a diaphragm on the inner periphery side. CONSTITUTION:Slits 6a, 6b are formed on a side face of a hollow-structured stationary blade 1. A communicating hole 10 is provided for communicating between hollow chambers 7, 8 formed on a diaphragm 2 on an outer periphery of a radius direction and diaphragm 3 on an inner periphery and a hollow chamber of the stationary blade 1. A steam blowout hole 11 opening approximately in a peripheral direction in a space between the stationary blade 1 and a moving blade 4 is provided in the hollow chamber 8. Thus differential pressure between the side face of the stationary blade 1 and the hollow chamber 9 causes water drop streams to be sucked from the slits 6a, 6b into the hollow chamber 9 so that the amount of large water drops being sprayed from the rear end of the stationary blade 1 can be decreased. In addition steam having effective energy flowed into the hollow chamber 9 is again blown out to a flow path from the steam blowout hole 11 due to the differential pressure to work.

Title: Alarming unit for forgetting key switching off
Inventor: MIZUNO AKIRA
IPC: B60T17/22
Filed: 1981-10-06
Abstract: PURPOSE:To prevent forgetting key switching off by allowing a buzzer to produce an alarm with different tones which can tell whether or not a key switch is turned on, in an alarming unit where a buzzer is designed to sound when the door is opened without locking the side brake. CONSTITUTION:When a side brake is operated, a switch S5 is turned on, and No. 7 pin (discharge terminal) for IC2 is grounded through a resistor R2. When a resistance value is predetermined so that voltages obtained by dividing by means of R4 and R2 the power supply voltage E may be lower than a reference voltage (voltage of No.5 pin) inside the IC2, a pulse oscillator 33 stops oscillator. When the door is closed, a switch 34 is turned off and the pulse oscillation is brought to a halt in the similar way. When the door is opened without locking the side brake, the pulse oscillation starts. The frequency of oscillation in this case is as follows: f1 1.44/(RA+2RB)C when a key switch S1 is turned off f2=1.44/(RA// R'+2RB)C. Therefore, f2 is higher than f1.

Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain an electromagnetic induction connector which enables power transfer between a vehicle body and a vehicle door, and prevents cores from colliding with each other, when the door is closed. SOLUTION: A primary coil unit 20, installed on the edge of an entrance 52, is provided with a guide structure 30. A primary core 22 supported by the guide structure 30 can slide and is held by a coil spring 33 at a location some distance from a door 50. When the door 50 is closed, the primary core 22 and a secondary core 12 installed on the door 50 abut against each other, generating an inertial force, which makes the secondary core 12 barely approaches the primary core 22. Since the primary core is held at a location some distance from the door 50, the cores 12 and 22 will not collide with each other. Permanent magnets 16 and 26 near the cores 12 and 22 attract each other, causing the secondary cores 12 and 22 to approach each other and join.
