An apparatus for measuring a length of an optical resonant cavity includes a frequency tunable light source, a beam splitter, a frequency modulator and an optical resonant cavity. The frequency tunable light source emits a beam. The beam splitter is disposed on the optical path of the beam for dividing the beam into a first beam and a second beam. The frequency of the second beam is modulated by the frequency modulator to differ from the frequency of the first beam by a beat frequency. The optical resonant cavity is disposed on the main optical path of the first beam and the main optical path of the modulated second beam. The first beam and the modulated second beam enter the optical resonant cavity for measuring a length of the optical resonant cavity, and a variation in cavity length is calculated from the beat frequency.

A plug of an artificial insemination tube for livestock breeding includes a leading portion and a viewing portion, each having different color layers or different hardness layers, and being formed by stacking and combining different foam layers. In an artificial insemination for livestock breeding, the plug installed at the front of a sperm delivery duct is inserted into a reproductive organ of the livestock, and secretion or fluid is attached and shown on surfaces of the plug leading portion and the viewing portion with different colors to achieve the effect of detecting the physical and physiological conditions of the livestock. In addition, the leading portion is a foam layer with relatively greater hardness, density, and smoothness, so that the plug may be entered into the female livestock body more easily, and the injection hole will not be deformed easily, so as to improve the smoothness and efficiency of the artificial insemination.

This invention relates to a device and method for optical nanoindentation measurement, according to which respective measurement results are obtained by having an indenter tip apply load to a fixed portion of a thin film, having an indenter tip apply load to a non-fixed portion of a thin film, and having a vibrating component transmit the dynamic properties of the vibration to the thin film. By combining the above measurement results in calculations, the Young's modulus, the Poisson's ratio, and the density of the thin film can be obtained.

An improved artificial insemination device with an inner catheter for animals is disclosed. The device is characterized by having a thin flexible tube and a positioning stop member installed respectively at the front end and rear end of an inner catheter that is movably inserted in the catheter tube. The thin flexible tube instantly extends forward from the front end of inner catheter when semen is squeezed into the inner catheter. Thus after the nozzle of catheter tube reaches the first cervical ring of the animal, the inner catheter only needs to extend inward a proper distance, and the semen, with the aid of squeeze force and the thin flexible tube advancing freely along the cervical tract, could be delivered to uterus smoothly, swiftly and accurately without causing trauma to the uterus. Also with the arrangement of the positioning stop member, the distance the inner catheter travels inward can be set. As the depth and location of inward extension are under proper control, the practice of artificial insemination is made simple, convenient, fast, efficient and safe for the animal.

An artificial micro-insemination device for animals is disclosed. The device has an elastic insemination sheath amassed in compressed state between the nozzle passage and the forward portion of center orifice of catheter tube, where the rear end of the elastic insemination sheath is secured to the front part of nozzle, characterized in which the catheter tube and nozzle are inserted into the uterus of animal with the nozzle positioned posterior to the first cervical ring, and by the pressure of semen dispenser squeezing in semen from the rear end of catheter tube, the extension member of the soft elastic insemination sheath instantaneously extend outward from the front part of nozzle and extends freely along the cervical tract to reach uterus, where coupled with uterine contraction, semen fluid squeezed into the extension member of insemination sheath is expelled into the uterus or the two ducts to uterine horns via the prearranged slits on the front part of extension member. Such design not only reduces the backflow of semen, it also offers the economic benefit of using minimal semen and improves the efficiency of artificial insemination.

An improved animal-use artificial inseminator comprised of an insemination tube with a nozzle at its front extremity into which an insemination sheath is inserted and a connector at the rear extremity of the insemination tube having a check membrane. After the insemination tube penetrates the female animal body vagina and the front end of the nozzle is nominally at the first cervical ring of the cervix, the semen bottle insertion tube is utilized to pierce the connector check membrane at the rear extremity of the insemination tube and when the semen at the insemination tube is squeezed, semen is automatically squeezed out of the insemination sheath. The soft insemination sheath proceeds along the cervix without the occurrence of friction, the front end smoothly moving forward until it reaches the position of the womb. Contractions of the womb are utilized to articulate the insemination sheath such that the contained semen is ejaculated into the two Fallopian tubes or the womb from the slits along the two sides of the front end. At the same time, after the semen bottle is pulled out, since the connector check membrane automatically opens and closes along with the contraction of the womb, not only is the semen in the insemination sheath prevented from backflow or leakage, but air is admitted for smooth and complete squeezing into the Fallopian tubes or the womb.
