20150252924 | SEALING DEVICE OF A LEVEL METER - A sealing device of a level meter is acid-and-alkali-resistant and pressure-resistant, and has a flexible outer tube, a plug, a female union connector and a male union connector. The flexible outer tube has an expansion neck formed on a bottom end thereof. The plug is mounted in the expansion neck. The female union connector is mounted around the expansion neck. The male union connector engages the female union connector by means of threaded engagement. The male union connector has a through hole for tying a weight such that the flexible outer tube is stretched along a force of a gravitational force of the weight. As being wholly and uniformly subjected to the gravitational force of the weight, the male union connector is less damage-prone. Accordingly, the tensile strength of the level meter is effectively increased, and a life duration of the level meter therefore prolongs. | 09-10-2015 |

20150077954 | ROTARY PADDLE LEVEL SWITCH - A rotary paddle level switch has a housing, a driving unit, two switches, a resilient member, a clutch, a transmission shaft, and a propeller. A resilient clip of the clutch holds a non-circular actuation section of the transmission shaft. When the driving unit drives the clutch to rotate, the transmission shaft and the propeller are driven by the clutch. When the propeller is rapidly rotated by suddenly exerting an excessively large external force thereon, as the resilient clip holds the transmission shaft by elastic force, the fast rotating transmission shaft removes itself from the holding of the resilient clip and is rotated without driving the resilient clip to rotate, thereby avoiding the transmission of the external force and damage to the driving unit. As the clutch just needs a clutch stand and a resilient clip to achieve the foregoing function, the level switch is structurally simple and relatively inexpensive. | 03-19-2015 |
20150035695 | FREQUENCY MODULATION CONTINUOUS WAVE RADAR LEVEL METER AND SIGNAL-TRACKING AND PHASE-LOCKING METHOD FOR THE SAME - An FMCW radar level meter has an RF signal processing module, an intermediate frequency (IF) signal processing module, and a computation and display module.

20140264098 | SELF-ALIGNMENT FILLING LEVEL DETECTING DEVICE - A self-alignment filling level detecting device has a reflector and a sensor detachable from each other. The sensor has a light emitter, a light sensor, and a controller. The light sensor receives different light intensities when the reflector is assembled to the sensor and when the reflector is not assembled to the sensor. Thus, the controller determines whether the reflector has been accurately engaged and aligned with the sensor or not based on sensing results of the light sensor. Since the reflector and the sensor are detachable from each other, either the reflector or the sensor can be replaced individually if any one of them malfunctions. | 09-18-2014 |
20140263978 | SELF-CALIBRATION METHOD FOR A PHOTOELECTRIC LIQUID LEVEL SWITCH AND APPARATUS USING THE SAME - The invention relates to a self-calibration method for a photoelectric liquid level switch and apparatus using the same.

20120063260 | TURBINE VIBRATOR - A turbine vibrator has a housing, an eccentric rotor mounted in an air chamber of the housing and two covers mounted respectively in two mounting recesses of the housing. Two threaded walls defined respectively around the mounting recesses of the housing have same threaded directions. Therefore, the mounting recesses, the air chamber and the other mounting recess are formed sequentially so axes of the mounting recesses and the air chamber are disposed along a same line. Manufacturing processes of the housing is reduced and shearing forces applied to the shafts of the eccentric rotor are reduced so the turbine vibrator has a prolonged useful life. Moreover, as a rotating direction of the eccentric rotor and the fastening directions of the covers are the same, when the turbine vibrator operates, the covers tighten against the housing. The first and second covers do not drop from the housing. | 03-15-2012 |
20110146889 | METHOD FOR MANUFACTURING DISPLAY DEVICE WITH OPTICAL/ELECTRONIC STRUCTURES - A disclosed method for manufacturing a display device with optical/electronic structures according to the present invention comprises: a first step for forming the optical/electronic structures on the primary side of a release film onto which an adhesive is applied, a second step for attaching the primary side of the release film to a substrate or a film, and a third step for removing only the release film from the substrate or film while the optical/electronic structures are attached thereto. According to the invention, the optical/electronic structures are transferred and attached to the substrate or film of the display device after firstly being attached to the release film. Therefore, the optical structure, such as a certain shaped micro lens, color filter, polarizing layer, or ITO layer, with optical characteristics or the electronic structure such as a circuit or electrode pattern like a thin film transistor (TFT) and in-cell phase difference film can be formed on the surface of the substrate or film very easily. That is to say, the optical/electronic structures can be formed very easily on the substrate or film of the display device in a desirable shape with uniform shape and size. In addition, the deterioration of an element of the display device can be prevented as a result of attaching the optical/electronic structures to the display device without directly radiating rays of light such as ultraviolet rays onto the display device. | 06-23-2011 |
