40results about How to "No calibration required" patented technology

Provided is a detecting device, which can be made so simple in constitution as to require no calibration. A thin film (2) of an inconductive material, which can be exposed to the space environment, is etched to form many detection lines (3) to become conductors at a predetermined array pitch, thereby to form a detection sheet element (1). The detecting device includes a detecting circuit (4) connected with the individual detection lines (3) of the detection sheet element (1). The detection lines (3) of the detection sheet element (1) are ruptured by space floating matters, when these space floating matters collide against the detection sheet element (1). Therefore, the conductions of the detection lines (3) are monitored at all times by the detecting circuit (4), so that the space floating matters having collided against the detection sheet element (1) are detected when the detection lines (3) are ruptured. A solving means can be adopted for detecting the effective diameter of the collided space floating matters from the number of the detection lines (3) cut out.

The invention discloses a probe compound for detecting spectrum temperature and a micro-capsule thermometer. The compound is a special triarylborane compound, and the probe compound can be taken as a micro-capsule thermometer, which can be used for real-time detection of temperature under different environments, especially for in-situ detection of static and dynamic temperature of micro-area and large-area. The micro-capsule fluorescence thermometer, which is prepared from the compound, has the advantages of rapid and convenient measurement of temperature, adaptability for various complex environments, furthermore, the two modes of spectrum identification and color scale identification can be selected individually, which is beneficial for the detection of spectrometer and the detection of colorimeter.

The invention belongs to the technical field of quality analysis and particularly discloses a quality analysis method based on the restricted theory of relativity and a mass spectroscope. The method comprises the following steps of: introducing irons of an object to be measured into an iron source area; accelerating the irons to 3*105m / s or more by using an accelerating electric field; introducing the irons into a field-free flying area to freely fly; introducing the irons into an iron detector; and determining the static mass of the irons according to the flying time of the irons in the field-free flying area. The mass spectroscope based on the method comprises the iron source area, the accelerating electric field, a field-free drift tube and the iron detector, wherein the accelerating electric field consists of three or more pulsed high voltages; and the pulsed high voltages are provided by corresponding electrodes. Data measured by the method and the mass spectroscope is the real mass-to-charge ratio of the irons, so the mass is accurate and is not required to be corrected; the mass spectroscope is high in sensitivity and resolution; the quality detection up limit is only limited by the detector; and the mass spectroscope is high in analysis speed, does not require scanning and can realize full-spectrum analysis within tens of seconds.

The invention provides a processing technology of a valve seat, comprising the following steps: die forging blank, pre-heat treatment, semi-finishing, final heat treatment, surface sandblasting, finishing, the processing method and device design of the valve seat are reasonable, through Forging the blank to improve the material structure can effectively improve the mechanical properties of the material, reduce material costs and processing time.
