  • Patent number: 5988123
    Abstract: A poppet valve which has a valve stem is moved up and down to open and close a valve port in an internal combustion engine of a vehicle such as an automobile. A moving coil is wound on a bobbin mounted to the valve stem, and a magnet is mounted to a yoke fixed to a cylinder head. A plurality of sensors detect working conditions of the engine to send a signal to a working condition discriminating portion of CPU. The signal is further sent to a valve timing lift pattern memory in which optimum valve timing and lift are set corresponding to the working conditions to generate an optimum valve position signal. In the meantime, an actual position of the valve is detected by a sensor on the yoke to send an actual valve position signal to a valve position detector.

  • Patent number: 5983847
    Abstract: A poppet valve is provided to open and close a valve seat in an internal combustion engine. At the end of a valve stem of the valve, a cylindrical support is fixed, and on the outer circumferential surface of the support, a moving coil is wound. There is formed an annular cavity in a yoke fixed to a bracket fixed on a cylinder head, and a permanent magnet is fixed in the annular cavity of the yoke. Between the permanent magnet and the yoke in the annular cavity, the support which has the moving coil is inserted. By a control system having CPU, an electric current is applied to the moving coil, thereby providing optimum valve timing and lift to decrease seating noise and improving engine performance.

  • Patent number: 4872335
    Abstract: A vibrating transducer for detecting the resonant frequency of a vibrating diaphragm and using that frequency to determine the pressure or density of a fluid contacting the diaphragm. The device includes a container having a diaphragm separating the cavity in the container into two chambers with the diaphragm preventing flow communication between the two chambers. A first fluid inlet in flow communication with the first chamber introduces fluid to the first chamber with that first chamber having an acoustic compliance less than the mechanical compliance of the diaphragm. The second fluid input is in flow communication with the second chamber and introduces fluid into the second chamber. By controlling the acoustic compliance of the chamber with respect to the diaphragm accurate measurements of the density or pressure of the fluid can be obtained.

  • Patent number: 4648280
    Abstract: Various forms of Karman vortex generators are used for flowmeters in which the vortices generated are used to create pressure differences on opposite sides of a vibrator plate whose frequency of rotation is measured optically as a measure of the fluid flow. One form of flowmeter, used to measure the quantity of air inhaled by an internal combustion engine, uses a chamber outside the path of the inhaled gas which is maintained at a negative pressure and which communicates both with the air line and outside air such that clean air is drawn in to keep the optics enclosed therein clean.

  • Patent number: 4593190
    Abstract: Apparatus for inspecting capsules comprises a carrier belt which is formed into an endless belt configuration and can carry the capsules, with the capsules received separately in through-holes in the belt, and a plurality of parallelly disposed rotatable rollers which have axes of rotation extending substantially in parallel with the flow direction of the capsules being carried by the carrier belt. The rollers rotate the capsules which are in contact therewith. An optical inspecting device is provided for optically inspecting the surfaces of the capsules which are rotated in contact with the rotary rollers. The apparatus can accurately inspect very small defects on the surfaces of the capsules irrespective of the type of capsules, and is simple as well as compact in construction.

  • Patent number: 4584883
    Abstract: A Karman vortex flowmeter for deriving the velocity or quantity of fluid flow is comprised of an upstream pillar for producing Karman's vortex streets or paths that has a substantially isosceles triangle cross section, a downstream pillar for producing Karman's vortex paths that has a substantially isosceles trapezoidal cross section, a vibration chamber, and a vibrator member supported in the vibration chamber in a state of mass equilibrium relative to a revolving shaft passing through its center of gravity such that it can vibrate torsionally about the revolving shaft. The base of the upstream pillar is substantially equal to the base of the downstream pillar, and the pillars are positioned so that the bases are parallel to each other and perpendicular to the direction of the fluid flow. The vibrator member is preferably provided with a pair of taut bands supporting the vibrator member which form the revolving shaft and a frame which supports the bands.

  • Patent number: 4470310
    Abstract: In the particular embodiments of the invention described herein, a Karman's vortex flow metering apparatus has an oscillating plate magnetically held at the vertex of a triangular chamber located outside a flow line. Within the flow line a Karman's vortex generator is mounted transverse to the flow direction and has vortex generating slits extending along its length. Pressure detecting slits located at the end of the generator near the detector communicate through short pressure transmitting lines with opposite sides of the chamber. The resulting oscillation of the plate is detected optically or magnetically to provide signals corresponding to the flow rate.

  • Patent number: 4354602
    Abstract: A device for inspecting the external appearance of solid medicine having a solid medicine supplying section, a first drum-shaped conveying section for conveying solid medicines supplied by the solid medicine supplying section, at equal intervals so that one surface of each piece of solid medicine is observed. A second drum-shaped conveying section receives the solid medicine from the first drum-shaped conveying section and conveys the solid medicine at equal intervals so that the opposite surface of each solid medicine is observed. First and second observing units are provided adjacent to said first and second drum-shaped conveying sections for observing both surfaces of each piece of solid medicine respectively. A third observing unit is employed for observing the thickness of each piece of solid medicine conveyed by the first and second drum-shaped conveying sections at least before the piece of solid medicine reaches the second observing unit.
