Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To remarkably damp vibration of a pole by fitting a container having swing frequency nearly conformed to the natural frequency of the pole in which viscous fluid is enclosed to the upper half part of the pole. SOLUTION: A damping device 8 in which viscous fluid such as silicone oil is enclosed in a cylindrical container 6 and having swing frequency nearly conformed to the natural frequency of a pole 1 such as lighting pole is provided, is fitted to the upper half part of the pole 1. Next, if necessary, the device 8 is fitted to the vicinity of the upper end part of the pole 1 where the amplitude becomes maximum by external vibration, so as to attain sure damping. In the case of a pole and the like in which a pair of pillars are combined together through a combined beam, the horizontal section of the container 6 is made, for example, into a rectangle, and the direction of higher natural frequency of the pole is set shorter than the direction of lower frequency.  The swing frequency of the device 8 is set high in the extending direction of the combined beam, and low in the direction squarely crossing with the combined beam. Hereby, vibration of the pole can be remarkably reduced, plastic deformation and breakdown can be prevented, and the sectional area can be minified.

Title: Speed controlling device of motor drive system
Inventor: TAKAGI TAKEO
IPC: H02P5/46
Filed: 1986-06-05
Abstract: PURPOSE:To continue operation at the speed to cause no slip and to increase the yield rate of products, by lowering the speed command value signal when extreme imbalance is caused by a mill roll. CONSTITUTION:The armature current of two motors for mill roll drive is detected by DC current transformers CT 1 and CT 2 respectively and is led to an adder AD. There, the quantity of load imbalance is indirectly detected from the differential current obtained by the comparison of both armature current. A comparator CMP turns OFF a switch S 1 and simultaneously turns ON a switch S 2 when the capacity of the differential current exceeds the threshold value set out by a setter VR. Thus the speed command signal N* is lowered.

Title: Treatment of zinc-chromium alloy electroplating waste solution
Inventor: OKOCHI TOSHIHIRO
IPC: C22B7/00
Filed: 1992-05-22
Abstract: PURPOSE:To inexpensively recover high grade zinc and chromium from a zinc- chromium alloy electroplating waste solution. CONSTITUTION:A solid matter is separated and recovered by vaporizing the zinc-chromium alloy electroplating waste solution with a combustion gas of 500-1200 deg.C and chromium and zinc are recovered by reduction treating the recovered solid matter. By this method, since neutralization treatment with an alkali solution at the time of recovering the solid matter is omitted and as a primary desulfuration is simultaneously enabled by the combustion gas, the solid matter small in sulfur and excellent in quality is recovered. As a result, the lowering of temp. and the shortening of treating time for succeeding reduction treatment are enabled. High-grade metal zinc and chromium is very economically recovered from the plating waste solution and trouble caused by disposing of the plating waste solution is solved.

Title: Programmable amplifier
Inventor: KUROODO BUANETSUKU
IPC: H03G1/00
Filed: 1992-05-22
Abstract: PURPOSE: To provide superior characteristic with respect to the pass-band and the noise figure to the amplifier by including a plurality of amplifier stages that have two different gains selected among them by different control bits and including at lease two identical configuration amplifier stages, whose gains are controlled by different control bits. CONSTITUTION: In order to improve the noise figure of an entire chain, an input amplifier stage A0 has a fixed gain, and the frequency versus gain characteristic is optimized in this stage. The gain of this stage is selected to compensate the attenuation (-6dB) caused by stages A3, A4, and the attenuation caused by a stage A6 resulting from a change from an input symmetrical mode in the stage A6 into an input asymmetrical mode in an output stage A7, and also the attenuation caused by the impedance matching between the output impedance of the stage A7 and an output load of, e.g. 50ohms at the same time. The stages A3, A4 of the same configuration are placed in the middle of the chain, by taking a noise problem due to different gains and the balance into account.  Thus, let a gain control bit number be n, then the stages A3, A4 have a gain of 2<n> -2<n-1> , and each stage including the input stage has a maximum gain which is smaller than 2<n-1> .
