Filed: 1981-03-13
Abstract: PURPOSE:To perform accurate finishing to a slick surface, by securing a primarily polshed wafer with a pressure-reduction holder and secondarily polishing the wafer with a one-side polisher. CONSTITUTION:After a wafer 1 is primarily conventionally polished (primary polishing) by a both-side polisher having a polishing surface provided by pouring a polishing agent onto a polishing cloth, the wafer is secondarily polished while a polishing agent 20 containing abrasive grains of extremely small size is dropped through a nozzle 13 onto a turntable 11 to which a soft polishing cloth 12 is bonded. To secure the wafer 1 throughout the secondary polishing, the wafer is sucked through an elastic sheet 14a and a pressure reducing passage 14b.

Filed: 1979-03-26
Abstract: PURPOSE: To promote the reduction of power consumption and the prolongation of a service life of the tube, by sealing an electrode that serves both as the discharge tube electrode and the stabilizer.  
     CONSTITUTION: If the power is fed from a power source 8, a foil-state electrode ribbon 3 jointed to a heater 4 is heated to emit much amounts of thermion from a thermion emitting material like barium oxides treated onto said ribbon, generate an intensified discharge between the electrode ribbon 3 and an electrode holding ribbon 3' in accordance with a voltage applied to across said both and allow a fluorescent unit 2 to emit a light if the mercury vapor is sealed in a glass bulb 1. Simultaneously with the discharge light emission, a stabilizer 5 that suppresses a short- circuit between the ribbons 3, 3' is actuated to prevent a discharge short-circuit and eliminate a damage of the bulb 1. The heater 4 can be rendered less susceptible of causing a disconnection because its temperature is about 700°C, resulting in the reduction of power consumption. A color glass of the same system as a luminous color of the fluorescent unit 2, if used onto a holder 7 of the above described stabilizer, can obtain a hue not seen in the conventional tube by composing the both colors.

IPC: H04N9/64
Filed: 1990-02-19
Abstract: PURPOSE:To satisfactorily continuously and automatically correct a hue by freely selecting the extent of hue correction effect and the range of hue correction in accordance with the extent of deviation from the I axis of a chroma signal. CONSTITUTION:Generally, three color difference outputs 13, 14, and 15 of a synthesizing circuit 12 can stably perform the hue correcting operation when three color difference signal waveforms R-Y, G-Y, and B-Y of the output of a demodulating circuit 2 are synthesized with the output of an amplifying circuit 5 in a proper synthesis ratio corresponding to levels of R-Y, G-Y, and B-Y by the synthesizing circuit 2. Since the correction effect of the hue correcting operation is reduced according as the hue of the chroma signal is deviated from the I axis, satisfactory continuous hue automatic correction is possible even in the case of the signal where the hue of the chroma signal is continuously changed. Further, two thresholds are freely selected to freely select the range of hue automatic correction.
