Title: Flow meter of karman's vortex
Inventor: OGAWA YUTAKA
IPC: G01F1/32
Filed: 1978-12-28
Abstract: PURPOSE: To establish the Karman's vortex flow meter low in the cost, simple in the construction and excellent in the accuracy, by jetting purge fluid from the both sides of vorgex producing body and detecting the change in the pressure accompanied with Karman's vortex via the purge fluid.  
     CONSTITUTION: Inactive gas is used as purge fluid, it is branched into the branch tubes 4a, 4b, and it is jetted in the tube path 1 from the vents 3a, 3b. Although the purge fluid flows with desired flow or flow speed at all times, if vortex is produced, pressure change is caused to the fluid, this is picked up and amplified at the detection elements 7a, 7b, and the flow or flow speed of measured fluid is measured with detection and count. Thus, since purge fluid continuously makes cleans the vortex production body surface, the attachment of dusts can be avoided, and since the detection function is located outside the tube, the construction can be simpler and massproduction can be made with less cost.

Title: Magneto-optical reproducing device
Inventor: SASAKI TORU
IPC: G11B11/105
Filed: 1986-07-11
Abstract: PURPOSE:To minimize phase difference of light beam that may occur from a disk, to completely eliminate DC component in a detection system, and to improve the C/N by controlling optical rotation so that the azimuth angle of the optical axis of polarization at a time an optical information recording medium is projected with light beam, comes approximately zero. CONSTITUTION:Assuming that an azimuth angle beta0 of the optical axis of polarization is occurring, when the azimuth angle is corrected i.e. the angle is made zero, the difference between the azimuth angle beta0 of the optical axis of polarization and the optical rotatory angle alpha of an optical rotatory plate 9 is taken as (x), then the relation between the angular difference (x) and the differential detection signal S generated by extracting the DC flucture component from a photoelectrically converted differential reproduced signal is such that the signal S passes through a point x=0 with zero output, has the opposite polarity in case the (x) is positive or negative, and increase its output level corresponding to the (x). By using such differential detection signal S, the azimuth angle of the optical axis of polarization can be corrected. That means that an actuator 28 is controlled by an optical rotatory plate driving circuit 27 to make the differential detection signal S come to zero so that the azimuth angle betaof the optical axis of polarization of a disk 1 is corrected to be zero.

Filed: 1983-09-05
Abstract: PURPOSE:To improve the transient response characteristic and reduce the exhaust emission of a fuel supply system which suspends fuel supply at decelerating operation by performing an interrupt injection prior to the steady injection at forced release of fuel supply suspension. CONSTITUTION:A fuel supply control system 5 comprising a microcomputer performs an interrupt injection by opening a fuel injection valve 7 for a fixed time during a fuel injection suspension period when the accelerator is pressed and an idle switch 1 is turned off. In the operation, the pulse width of the interrupt injection is previously decided by utilizing a map for steady injection on the basis of a throttle opening and a rotational speed N during the fuel supply suspension period, so that the interrupt injection can be performed without any delay. Therefore, the fuel adhered to the intake air passage wall immediately reaches to an equilibrium condition and the supply of thin air-fuel mixture is prevented. By this control, the transienet response characteristic is improved and the exhaust emission is reduced.
