Title: White light emitting diode and illumination system using the save
Inventor: SATO KENJI
IPC: G09F13/20
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To obtain a white light emitting diode of high color rendering properties and an illumination system by a method wherein a specified light emitting diode is used as a green diode. SOLUTION: A ZnTe monocrystal is manufactured and heated under a predetermined zinc vapor air pressure, thereby obtaining a ZnTe substrate having almost no deposition and having sufficiently carrier concentration. This ZnTe is used as a substrate, and Al is thermally diffused, so that a pn junction is formed and a light emitting diode is developed. As the results, a light emitting wavelength of 548 nm at room temperatures can be obtained due to a band end light emission. Furthermore, as ZnTe is of a direct transition material, the band end light emission is exploited to obtain a high brightness. In order to hold color rendering properties over the range of wide color temperatures, a wavelength of the ZnTe light emitting diode is a value close to an appropriate light emission wavelength, and a ZnTe green light emitting diode is suitable for a white light emitting diode by use of a three-primary-color. Furthermore, as the ZnTe light emission diode emits lights from a band end, there are not almost variations of the wavelength, thereby obtaining a uniform light emission wavelength characteristic in a wafer plane.

Title: Image forming device
Inventor: WAKI KENICHIRO
IPC: G03G15/16
Filed: 1990-06-13
Abstract: PURPOSE:To obtain an image of good quality by preventing scattering of toner on the upstream side and deterioration of the image due to it by providing an area where a transfer belt is abutted to an image carrier connected to the upstream of the transfer part, looking toward the running direction of the transfer belt. CONSTITUTION:A roll 43 is provided, other than a pair of rolls 41 and 42 on which the transfer belt is hung, in a position where the transfer belt 2 is abutted to the image carrier 1 in a place upstream from the transfer part, which is formed by facing the image carrier 1 and a transfer electrifying device 3, by an appropriate distance. With this constitution, since the transfer material fed from the right direction is brought over to the transfer part in a state adhered to the image carrier 1 upstream of the transfer part, no influence from electrical field of the transfer part is received, therefore, toner scattering is not generated, and a good transferring can be carried out. The position where the transfer material is abutted to the image carrier upstream of the transfer part differs by transfer means, but the desired effect can be obtained by making an abutted state between the image carrier and the transfer material up to the position where the electric field is less than 1/4 of that at the transfer part.

Title: Water flow quantity control device
Inventor: OHARA SUMIO
IPC: F16K17/30
Filed: 1982-09-01
Abstract: PURPOSE:To provide water flow quantity control device of small size and low noise, by combining a tapered inner core with an O-ring, receiving water on a soft plate, and controlling water quantity by a water flow switch. CONSTITUTION:When water passes through a clearance between an inner core 17 and an O-ring 16, water flow is most restricted to show jet flow, thereby reducing pressure at this area and attracting the O-ring 16 to a central portion in such a manner that the O-ring 16 surrounds an outer periphery of the inner core 17. When original water pressure is increased, and accordingly flow rate at the clearance is increased, the O-ring 16 further comes into contact with the inner core 17 to reduce the clearance. Therefore, even when water pressure is varied, the flow quantity passing through the clearance is maintained at a fixed value, thus showing water governor function. Then, the water jet flow strikes on a soft plate 25, thereby reducing noise. Further, water urges downwardly a float 28 to turn a lead switch 4 on by magnetic field of a magnet 29.
