Filed: 1978-08-08
Abstract: PURPOSE:To enable to increase the linearity and frequency characteristics, by operating the circuit at the best operating point of CCD, through the use of the circuit in which the DC level of the weighting output is not changed and only the AC amplitude is controlled with the control voltage. CONSTITUTION:In the weighting circuit of the charge transfer type transversal filter with the control voltage Vhk equal to inversion Vhk, the signal in which the DC level as the weighting output Vw is Vo and the AC signal is zero is produced on the output line 46, with Vhk> inversion Vhk, the AC signal of positive polarity having the DC level of Vo, and with Vhk< inversion Vhk, the AC signal of negative polarity having the DC level of Vo, is respectively produced. This enables the weighting  characteristics 50 which can offer arbitrary positive and negative weighting. In this  case. since the DC level of the input signal VIN and the inversion VIN is equally set,  the DC power consumption in the transistors 44 and 45 is 0, and further, since the  DC level constant, Vo, independently of the magnitude of Vhk and inversion Vhk,  Vo can be selected to the best point to the input bias of CCD, enabling the operation  at the best point for linearity.

Title: Removal of tin from silver or palladium solution
Inventor: HIRAKO MAMORU
IPC: C22B11/00
Filed: 1988-04-19
Abstract: PURPOSE:To separate tin in high efficiency from a silver or palladium solution containing tin, by dissolving metallic silver or palladium contaminated mainly with tin in a nitric acid-contg. solution and treating the resultant solution with activated carbon. CONSTITUTION:Firstly, metallic silver or palladium contaminated mainly with tin is dissolved in a nitric acid-contg. solution. Thence, the resultant solution is treated with activated carbon to effect adsorption of the tin on the activated carbon, thus removing the tin. If too much activated carbon is used, or the concentration of the silver or palladium is too low, adsorption of more silver or palladium will result, leading to reduction in yield. On the other hand, too little activated carbon will prevent the tin, etc., from being sufficiently removed. Hence, it is preferable that the amount of the activated carbon to be used be 0.1-10g/l and the concentration of the silver or palladium be 50-800g/l. When the concentration of the silver or palladium in the solution is relatively low, the amount of the activated carbon to be used should be reduced, and vis versa; thus reducing the adsorption of the silver or palladium on the activated carbon and obtaining the product in higher yield.

Abstract: PROBLEM TO BE SOLVED: To eliminate the dispersion of light quantity decline by fixing the response time of a light shielding mechanism even in the case that a diaphragm opening amount is different in an electronic endoscope for providing the light shielding period and reading all picture elements. SOLUTION: By providing a light shielding mask 23 provided with a rectangular opening 23A and moving a light shielding shutter 24 in a horizontal direction orthogonal to a diaphragm plate 22 moved in a vertical direction, since the light shielding period is set by the fixed response time of the light shielding shutter 24, the ratio of the light quantity decline is fixed.

Abstract: PURPOSE:To obtain a clear picture without distortion by taking notice of the flow of an area in a white picture or a black picture in an input line, judging it to be noise when the area is considerably small compared to the whole flow, permitting noise to be absorbed in a peripheral area and comparing characteristics. CONSTITUTION:Two one-dimensional image sensors 302 and 303 which are arranged in parallel to a manual feeding direction 308 are provided. The reflected light of a picture 307 is image-formed on the sensors by a lens 306. For detecting time till the second sensor 302 reads later the picture which the first sensor 303 reads in a prescribed position and reading the picture while the distortion of the picture is corrected, it is judged whether a short line in the picture is noise or not from the inclination of the white picture or the black picture in the line of the input picture. When it is noise, it is absorbed in the peripheral picture and the characteristics are calculated. Then, the characteristics are compared and a speed is detected so as to correct the distortion of the picture. Thus, the picture without distortion can be obtained.
