Title: Method and device for determining restricted color
Inventor: KOBAYASHI YUICHI
IPC: G06T11/00
Filed: 1993-03-10
Abstract: PURPOSE:To reduce the number of colors without generating a feeling of physi cal disorder in an original picture at the time of reducing the number of colors in picture data and displaying the picture by the small number of representative colors. CONSTITUTION:The appearance frequency of similar colors continuously appearing in respective picture elements on a picture is set up as the continuity value; of respective picture elements (S4). Each picture element has four values, i.e., values L*, a*, b* and the continuity, value. A four-dimensional (4-D) space consisting of four coordinate axes indicating the four values is supposed instead of a color space and respective picture elements in picture data are developed in the 4-D space and representative colors are determined by judgement/analysis (S11). In the case of finding out a division threshold in the 4-D space, the main component axis of the picture elements developed in the 4-D space is found out by main component anaysis (S7) and the frequency distribution of picture elements projected to the main component axis (S8) is found out (S9).

Title: Solid state image pickup device
Inventor: TANAKA SHIYOUICHI
IPC: H04N5/335
Filed: 1982-03-26
Abstract: PURPOSE:To reduce the vertical noise of an interline CCD image sensor, by shifting each potential well and potential barrier toward a horizontal CCD. CONSTITUTION:The 2nd potential wells 19A and 19B which store the vertical noise charges are separated from the 1st potential well 19C which stores the signal charge by three continuous potential barriers 20A-20C. Boundary regions 21A-21C having inclined electric fields are formed between each of barriers 20A-20C and wells 19A-19C provided in front of the barriers 20A-20C. The shallowest potential of the potential barrier is about +1V, and the deepest potential of the potential well is about +8V. The regions 21A-21C having inclined electric fields are formed with about ten transfer electrodes having stepped potentials (not shown in the diagram). Then each potential well and barrier are shifted toward a horizontal CCD by the change of the voltage which is impressed to the transfer electrode. In such a way, the vertical noise can be reduced for an interline CCD type image sensor.

Title: Manufacturing apparatus for single crystal
Inventor: YASUDA SADAO
IPC: C30B15/00
Filed: 1980-04-18
Abstract: PURPOSE: To manufacture a single crystal of a semiconductor with little crystal deformation and little pollution by carbon by allowing a gas to flow upward from the bottom of the pulling furnace of an apparatus for manufacturing a single crystal by a pulling method.  
     CONSTITUTION: When a single crystal is pulled, gaseous Ar is introduced into furnace 11 from inlet 20 and allowed to flow upward like solid line arrow A. Since the direction of the gaseous Ar agrees with that of heat convection (the dotted line arrows) caused in furnace 11, constant rising gas flows are formed in the vicinity of the opening of crucible 12. Accordingly, microcrystals of silicon oxide evaporated from molten semiconductor 12 and solidified on the furnace wall and the space are prevented from dropping into crucible 12, and gaseous CO generated from the carbon material of heating element 16 such as carbon heater is prevented from entering semiconductor 13. In addition, by this method the deposition of silicon oxide is restricted to the upper part of furnace 11, so by cleaning the upper part alone, the apparatus can be used repeatedly.

Title: Ultrasonic wave parametric speaker
Inventor: ARIKAWA YASUSHI
IPC: H04R3/00
Filed: 1990-02-28
Abstract: PURPOSE:To make a speaker small in size by providing a reflection member to a speaker box and reflecting an ultrasonic wave radiating from an ultrasonic wave vibrator without reducing the effective array length. CONSTITUTION:Reflectors 6, 7 are provided in a speaker box 5. The reflectors 6, 7 are made of a metal or the like well polished, and the shape and the combination position or the like are decided by the geometrical sound line method so that a sound wave radiates vertically from an acoustic filter 3 under the assumption that the sound wave reflected from an ultrasonic wave vibratos 1 goes straight in a near distance sound field. Thus, the ultrasonic wave radiating from the vibrator 1 is reflected in the reflectors 6, 7 and reaches the filter 3 to create an effective array length required for a parametric phenomenon together with a refracted path. Thus, the depth of the box 5 is decreased and the size of the speaker is made small.

IPC: H04B10/299
Filed: 1983-03-26
Abstract: PURPOSE:To expand the service life twice by detecting a degradated point of an in-use light emitting element, and applying the power to a spare light emitting element. CONSTITUTION:The operating time of an in-use laser diode LD10 reaches the degradation point Ip1 after the operating time t1, a bias current detecting circuit 20 detects it and its output is compared with a reference voltage of a comparator circuit 21, and an output of the circuit 21 turns on a DC power switches 23-1 to activate a spare LD16. Then, the degradation of the LD10 is progressed further at a time tf and a bias current If is detected by the circuit 20, and compared with a reference voltage of a comparator circuit 24. An output of the circuit 24 drives changeover switches 8-1, 8-2 to change over an in-use circuit 13 into a spare circuit 22. Since no bias current is applied to the spare LD in this way but applied after the degradation point of the active LD is detected, the service life is doubled by using the in-use and spare LDs having the same reliability.
