Abstract: PROBLEM TO BE SOLVED: To increase the fatigue resistance of a carcass and a belt and to improve maneuverability, particularly steering stability, by applying a steel cord with a specific structure for the reinforcing material of the carcass and the belt. SOLUTION: A steel cord 5 with the basic structure of 1×m (m: 2-7) or n+p (n: 1-3, p: 2-9), and the average gap tave between strands 6 defined by equation I satisfies equation II, where (e) is the number of the strands 6 of the outer peripheral layer of the cord 5, (f) is the diameter of the strand 6, and (d) is the diameter of the circumscribed circle of the strands 6. The average gap tave is set to 1.0 or above, the buckling of the cord 5 is suppressed, and fatigue resistance can be improved. The cord gap U-d subtracted with the diameter (d) from the driving interval U of cords 5 which is the cord center distance is set to the range satisfying equation III, thereby the entangling of the strands 6 between the cords 5 can be avoided when a ply is manufactured.

Filed: 1984-06-13
Abstract: PURPOSE:To control a distance between the surface of a recording medium and an objective at high accuracy without lowering stability by providing a measuring device that measures absolute position of the surface of the recording medium. CONSTITUTION:In this automatic focus adjusting mechanism, a position detector 21 consisting of a light emission element 22 and a light detector 23 is provided facing the surface of an original disk 8 to detect absolute position of the surface. When face deflection occurs in the original disk 8, the quantity of reflected light incident to the light detector 23 changes, and the output signal of the light detector 23 is used as a position measuring signal 24 whose level is changed according to the absolute position of the surface of the original disk 8. The measuring signal 24 is fed to another input end of an adder 25, and added to a distance measuring signal 20, and the output signal 26 is supplied to a focusing unit 7, and control is made to make the distance between the objective 5 and the surface of the original disk 8 converge to a fixed distance determined by a reference distance signal 17. The position detector 21 is so made that when the surface of the original disk is positioned at the position of focus of the objective, the position detection signal 24 goes to zero.

Abstract: PURPOSE:To reduce a steady speed by multiplying the gain constant of an element, constituting a closed loop, by a value which corresponds to the rate of an actual deviation value to the best deviation value of a control system, and also multiplying the gain constant of an element, which constitute an open loop, by it. CONSTITUTION:The number of feedback pulses from a position detector 4 in case of variation in total gain K to K' when an object 5 to be controlled has nonlinear characteristics is denoted as X1 and the target number of input pulses to a counter 3 is denoted as X0. In this case, a divider 12 divides the counter output X0-X1 by X0-X set as the best deviation value by a main control circuit 1. A coefficient alpha as the quotient is multiplied at a part 7 by a output of a D/A converter 6 and further multiplied at a part 10 by the output of the pulse frequency indivating circuit 9. As a rsult, the conversion gain K1 of the converter 6 is varied to alphaK1, and the conversion gain K2 of the circuit 9 is varied to alphaK2 in accordance with variation in the gain K of the object 5 to be controlled. Thus, the gain KK1 of a closed loop and the gain 1-KK2 of an open loop are specified.

Filed: 1989-05-15
Abstract: PURPOSE:To use the filter in a discharge system for high-temp. gases while the cost is low and to well remove microparticles of carbon by using carbon fibers as a filter stock. CONSTITUTION:The carbon fibers are used as the filter stock. Namely, the filter formed of felt or web made of the carbon fibers is used as the filter for removing the microparticles of carbon in fluid flowing in the discharge systems from combustion devices, such as various internal combustion engines and thermal power plants, etc. A pitch system, polyacrylonitrile system, phenolic system, etc., are used as the carbon fibers.

Abstract: PROBLEM TO BE SOLVED: To suppress the detection variance of toner-end caused by the difference of the output characteristic of a magnetic sensor by utilizing such a state where the analog output voltage of a toner sensor is fluctuated by the rotation of an agitator and detecting the toner-end based on the fluctuation of the analog output voltage. SOLUTION: The toner sensor 26 is fixed so that the detection surface thereof is brought into contact with the outer wall surface of a toner hopper for a developing device 20 and constituted so that the residual quantity of toner is detected by detecting the thickness thereof on the toner detection surface in the hopper 20 by utilizing the change of a magnetic field occurring according as the toner T is reduced. The analog output voltage from the sensor 26 becomes high when the large amount of toner T exists on the toner detection surface by the agitator and becomes low when the toner T is reduced. This output voltage is converted into a digital value by an A/D converter and stored in a RAM. By arithmetically operating the difference between both output values and comparing it with a value in a ROM, the toner-end is detected.
