Title: Silver recovery device
Inventor: NAKAMURA TAKASHI
IPC: C25C1/20
Filed: 1990-10-19
Abstract: PURPOSE:To realize the device capable of continuously and efficiently recovering silver by placing a high specific gravity liq. under a silver-contg. liq. and dropping the silver into the high specific gravity liq. to recover the silver. CONSTITUTION:A liq. having a higher specific gravity than a silver-contg. liq. 10 is placed close to the bottom of a tank 2, and silver is recovered by a circulating means 7 and a filter 8. The high specific gravity liq. is returned to the tank 2 through a pipeline 71. A cathode 4 is rotated by a motor 5, a current is supplied to an anode 3, and electrolysis is carried out. When silver is deposited on the periphery 42 of the cathode 4 and grown to some extent, metallic silver is detached in the form of scales, grains or lumps by the liq. current due to the rotation of the cathode 4, dropped in the silver-contg. liq. 10 and the high specific gravity liq. and trapped. Siver is continuously removed and recovered by this device, the surface area of the cathode is reduced, and electrolysis efficiency is enhanced.

IPC: G02B7/28
Filed: 1984-12-27
Abstract: PURPOSE:To execute a correct focus lead-in by detecting a fact that an objective lens has entered into a focus lead-in range, from a sum signal of an output of a focus detecting photodetector. CONSTITUTION:When a signal of a focusing start is sent to a saw tooth voltage generating circuit 11 from a sequence controlling circuit 10, a saw tooth voltage is sent to a servo-driving circuit 13 from the saw tooth voltage generating circuit 11, and a servo-coil 14 drives electromagnetically an objective lens 5 toward a disk 6 in the optical axis direction. Photocurrents of focus detecting photodetectors A, B are converted to voltages by amplifiers 15, 16, and its sum and difference are calculated by an adder 17 and a subtracter 18. When it is detected that an output of a comparator 19 has gone to a high level, a sequence controlling circuit 10 switches a switch 12 to a fixed terminal (b) side. As a result, an output signal (focus detecting signal) of the subtracter 18 is sent to the servo-driving circuit 13, the objective lens is driven by the servo-coil 14, and focusing is executed.

Abstract: PURPOSE:To predict the life of a cell in operation by measuring the output voltage as appropriate at the time of the ordinary operation and when the oxygen concentration is increased on each unit cell or a cell block of a cell stack and predicting and judging the cell life. CONSTITUTION:Many unit cells 1 are stacked to constitute a cell stack 5. A switching valve 9 is opened at the time of the ordinary operation, the air sucked from the atmosphere is fed to the air electrode 2 side of the stack 5 for power generation. Under this condition, the output voltage is invariably measured. On the other hand, the valve 9 is temporarily closed, a valve 12 is opened, the oxidizer gas with high oxygen concentration is likewise fed, and the output voltage is measured. These operations are repeated as appropriate to obtain the aging change of the output voltage and the voltage difference. The deterioration of the electrode catalyst layer 2b on the air electrode 2 side and the degree of the output characteristic reduction caused by the excessive wetting due to the electrolyte of the electrode and its future value are estimated based on the aging change pattern, and the cell life is predicted and judged.

Filed: 1990-10-19
Abstract: PURPOSE:To reduce flare light and to improve the S/N and gradation by integrating a condenser/lens member provided between the light emitting part of an illumination light source and an original surface with an original holding member. CONSTITUTION:The picture reader is composed of an original holding member 2 integrally formed with a light emitting diode(LED) 1 of the light source for illumination and a bar-shaped condenser/lens member 2a lacking in light converging ability only in the direction intersecting at right angles to the longitudinal direction, an image formation element 4 transmitting the information on the original surface through space, a sensor 5 optically converting light intensity information on the image-forming original surface into electrical information, and housing member integratedly holding these.

Abstract: PURPOSE:To improve the gain and to miniaturize a device by consisting an LC parallel tuning circuit of a printed coil which is printed meanderingly on a board and has a stray capacity and adjusting the stray capacity so that the resonance point is placed in the amplification band of an amplifier. CONSTITUTION:With respect to a choke coil, a printed coil 2 consisting of a conductive material like copper is formed on a dielectric board 1 as a meandering pattern having parallel parts 3. Adjacent parallel parts 3 and 3 of this pattern are formed with about 0.2mm gap between them to form a stray capacity, and the chock coil practically consists of the LC parallel tuning circuit where a capacitor consisting of the stray capacity and the inductance component of the printed coil are connected in parallel. The gap of the pattern is narrowed to increase the stray capacity to bring the resonance point of the LC parallel tuning circuit to a center f0 of the amplification band of the amplifier. Thus, a high gain is obtained in a relatively wide band, and the device is miniaturized.
