Filed: 1990-09-20
Abstract: PURPOSE:To widen the dynamic range by applying voltage/current conversion to a differential input signal, applying logarithmic transformation to the output, receiving each current after the logarithmic transformation and extracting a current output. CONSTITUTION:A collector voltage of a transistor(TR) Q3 and a collector voltage of a TR Q4 are made equal by a TR Q5 and a constant voltage source 22 in response to a voltage VE of an operational amplifier 30 at a post-stage receiving a current in this amplifier circuit and collector-emitter voltages VCE of the TRs Q3, Q4 are made equal to prevent the adverse effect of the Earley's effect thereby eliminating the DC offset.

Title: Video reproducing system
Inventor: NISHIHARA MICHIHARU
IPC: H04N5/95
Filed: 1984-11-26
Abstract: PURPOSE:To eliminate the variance of hue at the still picture reproducing time to obtain pictures of high quality by storing a reproduced video signal in a memory synchronously with the video signal and leading out the video signal stored in the memory synchronously with a signal having a preliminarily determined frequency thereafter. CONSTITUTION:The video signal of the first field is stored in an analog field memory 11 through a changeover switch S1 by a transfer clock synchronized with jitters. The video signal of the first field is led out from the memory 11 by a pulse which is not synchronized with jitter and has a certain frequency, and this video signal is stored in the memory 11 by the pulse having a certain frequency. Thus, all reproduced pictures of the first field are obtained continuously. In case of the input of the video signal including jitter, the transfer clock synchronized with jitters is used for the first input and another fixed transfer clock which is not synchronized with jitter is used as the transfer clock for reinput in this manner to reduce jitter of the video signal outputted to a video circuit 22.

Title: Semiconductor device and its manufacture
Inventor: HIGUCHI HISAYUKI
IPC: H01L29/786
Filed: 1993-10-05
Abstract: PURPOSE:To improve the uniformity of film thickness by providing a sidewall with a specific angle of inclination on the side of a silicon film island. CONSTITUTION:An oxide film, about 10nm thick, is formed on a substrate comprising a silicon substrate 51 of an SOI wafer, an oxide film 52 of a film thickness of 0.3mum, and a silicon film 53 with a lack of uniformity of its film thickness under 1mum. A nitride film 55 is formed on top of it. Then, the double- layer film of the oxide film and the nitride film 55 are processed to leave only the double layer film of a desired region. This SOT substrate is etched in an aqueous solution of hydrazine hydrate to eliminate a silicon film not covered by the oxide film and the nitride film 55. The characteristic of this etchant is that the sides of the etched silicon are inclined at an angle of about 54 degrees (under 15 degrees). Film thickness uniformity can be improved by using a new selective etching process for the wafer of this degree of uniformity.

Title: Treatment method for making dusts containing heavy metals harmless
Inventor: SHIMURA SUSUMU
IPC: B09B3/00
Filed: 1988-10-04
Abstract: PURPOSE:To convert harmful heavy metal into a water-insoluble sulfide to prevent it from flowing out by, in the treatment of dusts containing heavy metals produced in a waste incinerator, adding sulfurizing agents to the dusts in a direct-energizing melting furnace. CONSTITUTION:When dusts containing heavy metals are treated in a direct- energizing melting furnace, fused slag 9 composed mainly of water-insoluble oxides is formed, whereby the heavy metals therein are made harmless to be discharged from a lower outlet 7, while molten salts 10 composed mainly of water-soluble alkali metal salts are formed over the fused slag 9 to be discharged from an upper outlet 6. Since the molten salts are soluble in water, heavy metals contained therein flow out of the furnace, whereupon, sulfurizing agents (e.g. Na2S, K2S etc.) are added to the dusts. The quantity of additives is preferably two equivalents or more of the total amount of the heavy metals in the dusts and CaCl2produced by the use of Ca(OH)2 for removal of HCl in exhaust gases. As a result, the heavy metals are converted to water-insoluble sulfides, preventing thereby harmful heavy metals from flowing out.
