  • Patent number: 6610954
    Abstract: A direction indicator placed on one site of a sorting block indicates, for a given good, the direction towards a nominated slot through which the good is to be placed in the block. This arrangement makes it possible for the hauler to immediately put a good into a nominated slot without looking around at sorting blocks at large, which will lead to the improvement of work efficiency. Moreover, because this will moderate the burden imposed on the hauler, the number of wrongly hauled goods would be greatly reduced. If a good is passed through a wrong slot, it is recognized by a sensor and then an alarming means is activated to generate a buzzing sound or a blinking light to alarm. This arrangement will make it possible to greatly reduce the number of wrongly hauled goods.

  • Patent number: 6607633
    Abstract: The present invention describes a plasma generating device comprising a wave guide; a radiative part having slot antennas, each of said slot antennas being adapted to radiate electromagnetic radiation; and a plasma generation chamber being connected to the radiative part via a window made of a dielectric material and being adapted to receive the electromagnetic radiation from the slot antennas; wherein the dimensions of the radiative part are locally modified or are locally changeable, so that the actual wavelength of the microwave is allowed to be locally changed, thereby the amplitude distribution of the electromagnetic radiation towards the plasma generation chamber can be controlled. The present invention also describes a plasma processing apparatus including such a plasma generating device.

  • Publication number: 20020153773
    Abstract: A track roller is provided, in which a bushing case and a roller body are integrated inside the track roller, to accordingly facilitate an assembly. Also, since a lubricant path is formed in the roller body, a lubrication work is improved. The track roller having a pair of left and right bushings inserted on the central protrusion of the central axis and which is rotatably fixed, includes a bushing case inserted on an outer circumferential surface of one side of the bushing, a roller body provided in the outer circumferential surface of the bushing case and formed in a shape corresponding to the bushing, in which an extension is formed on the other side of the bushing and provided in the outer circumferential surface of the bushing, and a combiner for fixing the bushing case and the roller body so that they are not dismantled from each other. As such, the number of components is reduced to thereby facilitate an assembly and shorten an assembly time, which enhances an economical efficiency.

    Abstract: The present invention provides an optical system for a head mounted display. The optical system of the present invention comprises a light source, a reflector for diffusing light from the light source, a reflection-type liquid crystal display panel for displaying an image by means of the light which is irradiated from the reflector, and a prism disposed in front of the reflector for magnifying the image of the liquid crystal display panel. In particular, the light source is a light emitting diode, and the reflector is constructed to be aspheric such that distortion aberration of the image of the liquid crystal display panel, which is emitted from the reflector, can be corrected. According to the present invention, an advantage of enhancing light efficiency can be obtained by including the light emitting diode and the reflector for diffusing the light generated from the light emitting diode.
