Patent JP-H0745234-A (JP)
Title: External electrode discharge lamp and lamp built in equipment
Inventor: TAKAGI MASASANE
IPC: H01J65/00
Filed: 1993-07-28
Abstract: PURPOSE:To improve brightness of light outgoing from an aperture by arranging one of a pair of external electrodes so as to be opposed to a light irradiating direction of the aperture or the like. CONSTITUTION:The inside of a straight pipe-shaped glass-made bulb 12 of an external electrode fluorescent lamp 11 is sealed with rare gas at a suitable pressure, and an internal total surface of the bulb 12 is coated with a phosphor film 13, to form an aperture 14 by eliminating the film 13 along the axial direction by a prescribed width. A pair of band-shaped external electrodes 15a, 15b are pasted to an external surface of the bulb 12, and the one electrode, for instance, 15a is opposed to the aperture 14 in a diametric direction of the bulb 12. When lamp voltage is applied across a pair of the electrodes 15a, 15b, a discharge is performed between the electrodes 15a, 15b, and a positive column is formed in the bulb 12. Consequently, a film 13 inside of the electrodes 15a, 15b emits light of brightness higher than the other part. Since the aperture 14 is opposed to a high brightness part of the phosphor film 13 inside of the electrode 15a, brightness of light outgoing from the aperture 14 is improved.

IPC: G03G15/09
Filed: 1984-09-06
Abstract: PURPOSE:To shorten the start-up time of development and prevent a developer from falling before and after the development by turning only a developing sleeve before and after the development. CONSTITUTION:The developing sleeve 3 of a developing device which is rotated to a development position makes an about half clockwise turn before a rotary station 2 rotates and a developer is stuck on the surface of the sleeve 3. A developer 4 is stuck on the surface of a sleeve 4 previously, so the start-up time at the start of development is shortened. Further, the rotation of a magnet roller 5 is stopped after the development and before the rotary station 2 rotates and only the developing sleeve 4 is rotated clockwise by about one quarter to move a developer from the surface of the developing sleeve 4 where it contacts a photosensitive drum 1, thereby preventing the developer from falling during the movement of the developing device.

Title: Floating point adder-subtracter
Inventor: TSURUTA HIDEYO
IPC: G06F7/485
Filed: 1992-07-14
Abstract: PURPOSE:To execute the addition and subtraction of a floating point accompanying a rounding-off at a high speed in a circuit constitution whose scale is smaller than used to be. CONSTITUTION:A floating point adder-subtracter is constituted of three fixed- point part inverting means 115-117 which are operated mainly in parallel, and two fixed-point part adders 118 and 119, and the rounding-off and absolute value of a fixed-point part in the floating point addition and subtraction is exclusively generated in the following cases. In the case of a real addition or a real subtraction in which the difference of excomponents is not 0, two rounded results are simultaneously calculated, and the correctly rounded results are selected by the constituting elements. In the case of the real subtraction in which the difference of the excomponents is 0, the difference of fixed-point parts and the number of the code inversion are simultaneously calculated, and the absolute value of the difference of the fixed-point parts is selected by the constituting elements. Therefore, it is not necessary to provide a borrow predicting mechanism, so that the scale of the circuit can be sharply reduced. And also, a critical path is shortened according to it, so that the high speed of an operating frequency can be attained.
