Abstract: A storage container having a cover and a disc base is disclosed. The storage container is used for storing information storage media. The cover of the storage container has a locking element used to wrappedly engage a locking mechanism positioned on the disc base. When the locking mechanism is engaged in the locking element, the storage container is securely locked. In order to separate the cover and the disc base, the connecting part has to be broken. Accordingly, the storage container is lockable and prevents the information storage media disposed therein from being stolen.

Abstract: A freeze safe valve includes a housing coupled between an upstream tube and a downstream tube of a water flowing or supplying line for shutting off the water flowing or supplying line and for opening a drain port in response to the formation of ice on the downstream side of water flowing or supplying line, and thus for alleviating the pressure on the downstream side and for precluding or eliminating water damage from frozen, broken pipes, etc. A flexible valve member is disposed in the housing for selectively blocking the drain port of the housing by the fluid flowing into the housing and for selectively blocking the an orifice of a plate by a spring member.

Abstract: A remote vehicle diagnosis system comprises an electronic control unit, a signal transmitter, a first network communicator, a second network communicator, a signal reproducer/learner and a diagnosis instrument. The electronic control unit, the signal transmitter and the first network communicator are connected to each other by line. The first network communicator and the second network communicator are connected to each other via signals. The second network communicator, the signal reproducer/learner and the diagnosis instrument are connected to each other by line. By such arrangements, the diagnosis instrument can directly and remotely control the signal parameter adjustment of the electronic control unit, thus improving the working efficiency of the electronic control unit.

Abstract: A sub-wavelength grating structure that has a very broad reflection spectrum and very high reflectivity comprising segments made of high refractive index material disposed on a layer of low refractive index material and a low refractive index material disposed above and between the segments. The index differential between the high and low index materials determines the bandwidth and modulation depth. The larger difference in refractive indices gives rise to wider reflection bands. The reflection is sensitive to parameters such as the grating period, the grating thickness, the duty cycle of the grating, the refractive index and the thickness of the low index layer underneath the grating. The design is scalable for different wavelengths, and facilitates monolithic integration of optoelectronic devices at a wide range of wavelengths from visible to far infrared.
