Title: Apparatus for measuring volume
Inventor: TANAKA HARUTO
IPC: G01F17/00
Filed: 1993-12-27
Abstract: PURPOSE:To reduce errors when a volume is measured, thereby to improve a measuring accuracy by driving a volume-changing means intermittently and restricting the generation of heat at the volume-changing means. CONSTITUTION:An analog switch 2 is connected to an oscillator and to a speaker 33 via a driving amplifier for the 1 speaker. A connecting part of a timer circuit 4 to a first delay circuit and a second delay circuit is connected to the analog switch 2, and an output terminal of a NAND circuit is connected to a sample hold circuit. A width of an intermittent signal output from the timer circuit 4 is set based on using conditions of the apparatus, particularly, heat-generating characteristics of the speaker 33. The speaker 33 is intermittently driven and a measured volume value is held before and after the speaker is turned into a non-operating state. Accordingly, the generation of heat when the speaker 33 operates or when the volume changes is limited, so that errors when the volume is measured are reduced.

Inventor: OZAWA HIROMITSU
IPC: G05D7/00
Filed: 1989-12-25
Abstract: PURPOSE:To remove an unnecessary input check error function and to attain considerably precise bidirectional flow rate control by deciding the flow direction of fluid based on a positive or negative differential pressure signal from one differential presure type flow rate detection means. CONSTITUTION:A differential flow meter 15 detects a differential pressure between an R-direction control valve 1 and an L-direction control valve on a fluid line. When there is the differential pressure, the positive or negative signal is inputted to a direction decision unit 16. The direction decision unit 16 decides whether the flow direction of fluid is in an R-direction or an L- direction based on the differential pressure signal from the differential flow meter 15 and the signal is inputted to an R-direction switch 23 and an L- direction switch 24. On the other hand, an R-direction flow rate converter 17 converts the positive differential pressure signal into a flow rate signal and it is inputted to an R-direction flow rate controller 19. An L-direction flow rate converter 18 similarly converts the negative differential pressure signal and inputs it to an L-direction flow rate controller 20.
