Title: Process controller
Inventor: HIROI KAZUO
IPC: G05B13/00
Filed: 1985-07-06
Abstract: PURPOSE:To attain the control of the integration time to the change of the target value without giving any change to the disturbance control state, by using an advance/delay arithmetic means which changes equivalently the integration time to the change of the target value. CONSTITUTION:The target value SV is calculated by an advance/delay arithmetic part 5 and a subtraction part 7 subtracts the measured value PV from the output signal of the part 5. Thus a deviation epsilon2 is obtained. An integration arithmetic part 9 performs the integration operation to the deviation epsilon2. Then the output signal of the part 9 is added with a deviation epsilon1 at an addition part 11. Then the output signal is multiplied by a proportion gain Kp through a proportion gain part 13. Here the coefficient beta of the part 5 is changed to fix the integration term against disturbance. Under such conditions, the integration time can be changed equivalently.

Title: Variable pulley
Inventor: YAMADA MASAHIKO
IPC: F16H9/18
Filed: 1995-06-15
Abstract: PURPOSE: To reduce a centering offset by installing at least three sets of ball splines lying between a movable flange and a driving shaft, making a pitch circle center passing through the ball center accord with a driving shaft center, and installing a different ball in a diameter equalizing each load burdened of respective balls. CONSTITUTION: Ball diameters DA, DB and DC of each spline 14 lying between a movable flange 9a of a main variable pulley and a driving shaft 1 of a transmission mechanism come to DA<DB, DC, but a center q1 of a pitch circle passing through centers p1 to p3 of the balls and a shaft center (p) of the driving shaft 1 are accorded with each other. Moreover, an array of balls in a sense along the shaft center of the driving shaft 1 becomes 14a>14b>14c in diameter in order from the nearest side to the flange 9a, so that load on each ball becomes uniformized at all lines. Therefore any partial abrasion in each ball and a spline groove due to local load concentration is avoided, so an offset in the variable pulley comes to very smallness in consequence.

Abstract: PURPOSE:To enable compact light works to be securely separably supplied with high speed by disposing a chute holding block holding a chute on a second leaf spring and holding slidably a work stopper while disposing an escape bed connected to the chute on a first leaf spring. CONSTITUTION:First, a series of works arranged in order are dropped and the works are separated by lifting from the leading work unit 29a a series of other works.

IPC: H01M8/04
Filed: 1981-09-24
Abstract: PURPOSE:To provide a fuel cell device which enables the differential pressure between a fuel and an oxidant to be regulated within the minimum value, and enables the  pressure of the oxidant to be higher than that of the fuel at any part of the surface of  an electrode constantly even when the flow rate of the fuel or the oxidant, the load or  the fuel cell is changed. CONSTITUTION:The pressures of a fuel and an oxidant inside a pressure case 2 are adjusted to become the minimum at the point (P). The pressure of the oxidant is made  higher than that of the fuel at any other point in the case 2. In order to achieve the  above mentioned condition, a differential pressure gauge 3' on the fuel side is installed  at the inlet of the fuel, and a differential pressure gauge 4 on the oxidant side is installed at the outlet of the oxidant as usual so as to detect the differential pressures  independently. After that, the detection signals are compared with set values through  computing elements 5 and 6, and gas-exhaust valves 7 and 8 are controlled with the  operation signals so that a pressure distribution as indicated in the figure is realized.  By the means mentioned above, evek when the flow rate or the load changes, or when the pressure loss changes according to the alteration of the fuel cell, the diffeential  pressure at the point (P) is constantly zero, and the differential pressures at the other  points change only slightly.
