Title: Water-level adjusting device
Inventor: SUMIKURA SUSUMU
IPC: F02B1/04
Filed: 1978-09-11
Abstract: PURPOSE: To stably adjust water-levels in excellent control accuracy however the areas of the water surface change due to the variation of water-levels, by altering the settlement rates of water-levels in response to the alteration of water-levels.  
     CONSTITUTION: The deviation signals of an adder A 1  are converted into signals corresponding to water-levels H 1  changing by time constants Tx being proportional to the areas A of water surfaces, the signals and the set water-level H 1 are compared by means of an adder A 2  and variable water-level settlement rates Rx are altered from relationship between the deviation signals and signals corresponding to said water-levels H 1  and added to an adder A 3 . Thus, the water-level settlement rates Rx can be changed each time in response to the variation of the water-levels H 1 , and water-levels can stably be adjusted in excellent control accuracy in an extent that the flow rate of a hydraulic turbine ranges over non-load flow rate from rated load flow rate however the areas of the water surface shift due to the alteration of the water-levels H 1 .

IPC: H02J3/00
Filed: 1990-04-27
Abstract: PURPOSE:To shorten a processing time, by deriving an evaluation point on the basis of the supply densities of feeders and the supply distances associated with nodes, regarding the combination of the feeders and the nodes, each having the shortest route for transferring a load, and by determining the feeder having the highest evaluation point as a supply feeder. CONSTITUTION:A shortest route for transferring a load and a next shortest route for transferring a load are searched on each of nodes, the nodes being objects for which the loads are interchanged, and searched every attendant one of feeders F1-F3. Regarding the combination of the feeders F1-F3 and the nodes #1-#9, each having the shortest route for transferring a load, an evaluation point is derived on the basis of the supply densities of the feeders F1-F3 and the supply distances associated with the nodes #1-#9. The one of the feeders F1-F3 which has the highest evaluation point is determined as a supply feeder. Therefore, while grasping the whole of interchanging loads, a collective batch processing can be performed. Thereby, the quality of the obtained configuration of interchanging loads is improved, and the processing tried again and the repeated processing are reduced.

Filed: 1990-04-27
Abstract: PURPOSE:To facilitate the setting and control of applied voltage and to enhance measuring accuracy or efficiency by measuring the plateau characteristic of voltage-current characteristic different at every plural samples using an operation/control means (microcomputer). CONSTITUTION:When there are a plurality of sample solutions 1, applied voltage V is scanned to be applied to a detection electrode 3a through a D/A converter 7 and a applied generating circuit 8 under the control of an operation/control means muP 6. A detected current I is read from a detection electrode 3b through a preamplifier 9 and an A/D converter 10. At this time, the muP 6 selects a mode to step up an applied voltage value at a predetermined interval to measure the value of the current I. Hereinafter, in the same way, values showing plateau characteristics different at every samples different in residual chlorine concn. can be simply measured. On the basis of these measured values, the initial value voltage or voltage gradient of applied voltage compensation characteristics in certain residual chlorine concn. can be set and, by this method, the optimum applied voltage can be set and controlled.

CONSTITUTION:Since the first and second connection members 50, 51 are connected through a plurality of slide parts consisting of bearings 53, 53 and shafts 55, 55, even when there is positional shift delta between these slide parts and the running line of a steel belt 17a, the phenomenon revolving around the slide parts by the effect of the tension of the steel belt 17a can be prevented and moving force can be stably transmitted. Therefore, high accuracy is secured with respect to the movement in a Y-direction of the pen 4 mounted on the X-direction carriage 13 moving with the movement of a Y-direction carriage 11a. Since the X-carriage connection means connecting the X-direction carriage 13 and a steel belt 35 is also constituted of the same slide system as the first connection means 30, high accuracy is secured with respect to the movement in the X-direction of the pen 4.

Title: Aromatic polyester resin
Inventor: UENO RYUZO
IPC: C08G63/60
Filed: 1987-05-07
Abstract: PURPOSE:To obtain a melt-moldable aromatic polyester resin excellent in heat resistance and mechanical properties, containing four specified kinds of structural units at a specified ratio. CONSTITUTION:An aromatic polyester resin containing at least 95mol.%, based on the total structural units, structural units of formulas I, II, III and IV and containing 16-19mol.%, based on the total structural units, structural units of formula I. The total of structural units of formulas II, III and IV amounts to 81-84mol.% of this polyester, and the molar ratio of the structural units of formula II to the structural units of formulas II, III and IV is 9-1. If this ratio is above 9, the bending strength and impact strength of the formed polyester are markedly decreased, and if this ratio is below 1, the m.p. of the formed polyester is so high that its melt polymerization is difficult and only a polymer of low MW one can be obtained. Although the formation of the polyester from monomers is preferably carried out by melt polymerization or slurry suspension polymerization in a medium, melt polymerization is particularly preferable.

Filed: 1988-05-10
Abstract: PURPOSE:To remove generation of cracks from a core so as to decrease drop of inductance at a thermal shock test, heat resistance test, etc., by forming a resin mold part out of thermosetting resin having flexibility. CONSTITUTION:A choke coil 6 is equipped with a bobbin 1, a coil 2 wound around the bobbin 1, and a core 4 inserted into a vacant core 3 of the bobbin 1, which is covered by a resin mold part 5, and the resin mold part 5 is formed of thermosetting resin having flexibility. For this resin, it is preferable to use thermosetting resin whose dynamic modulus is 20-150kgf/mm<2>, and glass transition point is 0-30 deg.C. Hereby, fastening force at the time of setting shrinkage of the resin mold part 5 and thermal expansion and contraction of the resin mold part 5 during thermal shock test, heat resistance test, etc., are absorbed by flexibility of the resin mold part 5, and cracks cease to occur at the core 4 and drop of inductance can be decreased.

Abstract: PURPOSE:To ensure a highly efficient transmission of the electric power in the desired direction, by using the radiation elements for both reception and transmission of the pilot wave and then turning the maximum radiating direction of the transmitting wave radiation pattern to the arriving direction of the pilot wave. CONSTITUTION:An equal distance d1 is secured among the pilot wave receiving elements D1-DN which are provided at points Q1-QN; and an equal distance d2 is secured among the transmitting elements E1-EN which are provided at points R1- RN respectively. When the pilot wave arrives in the direction theta0, the lengths of the pilot wave and the transmission wave are defined as lambda1 and lambda2. And the direction theta0 becomes equal to the maximum radiating direction thetam when d1/lambda1=D2/lambda2 is satisfied. And thus the transmission wave is radiated toward the arriving direction of the pilot wave, and accordingly the electric power of the desired level can be transmitted in the opposite direction.
