Title: Indicating mechanism
Inventor: NISHIHARA TADASHI
IPC: G01L7/00
Filed: 1978-10-03
Abstract: PURPOSE: To realize the minaturization and high precision for the indicating mechanism with a simple constitution of the power balance type in which the servo system is formed with use of the nozzle, the flapper mechanism and the bellows each.  
     CONSTITUTION: With application of input signal voltage Pin, input bellows 2 has the rotary motion counterclockwise with flexure 24 used as the intermediate vertical axis. Thus the gap is decreased between nozzle 5 and balanced beam 3, and the back pressure of the nozzle increases. Accordingly, the inner pressure increases for displacement output bellows 6 into which the nozzle back pressure is introduced, and bellows 6 has the clockwise rotary motion with flexure 64 used as the intermediate vertical axis. And pointer 8 indicates the pressure of that time. On the other hand, the right end of feedback spring 7 is shifted toward the right by the rotary motion of bellows 6 to apply the feedback force to beam 3. As a result, beam 3 stands still at the position where the balance is secured between the force caused by bellows 2 and the feedback force.

IPC: G01F1/05
Filed: 1983-07-04
Abstract: PURPOSE:To obtain a flow-rate detecting device, which detects the rotation of a rotary body, without mounting a permanent magnet to the rotary body, by detecting the rotation of the magnetic rotary body, which is rotated by a turning axial flow by a magnetoresistance element, and operating and processing the signal. CONSTITUTION:When a fluid flows to an outlet port 4 from an inlet port 3 of a flow-rate detecting device, a turning axial flow is obtained by fixed blades 5. A magnetic spherical body 6 is turned at a speed proportional to the flow rate through a flow-out preventing body 7. The number of rotation is detected through a magnetoresistance element 10 and a permanent magnet 9 and processed and operated by a control circuit 11. Thus the flow rate is obtained. Since the rotation of the rotary body 6 is detected without mounting a permanent magnet to the rotary body 6, poor rotation due to the attachment of foreign materials such as iron powder in the fluid does not occur.

IPC: F02D41/36
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To correct any dispersion in a combustion state among cylinders in a highly accurate manner by eliminating the effect of compression pressure or the like of other cylinders, and grasping the torque of a cylinder in a combustion stroke accurately. SOLUTION: In the case of a four-cylindered engine, a crank angle sensor outputs a reference signal at 180 deg. CA, through which a cylinder in a combustion stroke is judged. In the same combustion stroke, an angular velocity of a crankshaft is detected in the preset two spots (θ1 to θ2 and θ3 to θ4). With each angular velocity in these two spots and sampling time dt between both of them, angular acceleration in the crankshaft is detected at each combustion stroke. On the basis of a deviation between the whole cylinder mean value and the cylinder-classified mean value of the angular acceleration, fuel injection quantity or ignition timing of each cylinder is corrected, and thus feedback control is carried out so as to lessen a dispersion in each combustion state among cylinders.
