Title: Integration circuit
Inventor: UNOSAWA NOBORU
IPC: G06G7/186
Filed: 1981-12-16
Abstract: PURPOSE:To prevent an effect of the drift which is caused when an input is integrated for a long period of time, by compensating the discontinuous output of a D/A converter which the output of an integrator which is reset with each certain time and then obtaining a continuous analog integration output. CONSTITUTION:An input signal is integrated by an integrator (IG) and increases as the time elapses. The output of the IG is compared with the set voltage Vref through a comparator COM. The COM delivers a signal when the output of the IG exceeds the set voltage. This signal is differentiated by a capacitor C and a registance R and applied to a switch SW. Thus the SW is turned on to reset the IG. The output pulses of the COM are counted by a counter COU, and this count value is applied to a D/A converter to be converted into an analog signal. This analog output increases with steps as shown by the solid line in the figure (c) and applied to an adder. As a result, the analog output changes as shown by the dotted line in the figure (c). In other words, the discontinuity is compensated for the output of the D/A converter by the output of the IG.

Abstract: PROBLEM TO BE SOLVED: To obtain a load cell balance in which the calculation can be carried out with high accuracy even upon temperature variation by calculating the load while subjecting the output information from a load cell to temperature correction based on the temperature detected by a temperature sensor. SOLUTION: The majority of a load W being applied to a load table 16 is received by a load cell 4 through a load transmission mechanism 17 and the load is measured based on the displacement thereof. At a temperature correcting section, the load cell 4 imparts an input load W sequentially and independently and the output value therefrom is stored. On the other hand, the temperature is varied sequentially and the output value from the load cell 4 is stored while measuring the temperature with a temperature sensor and registered as a temperature compensation sensitivity coefficient of the load cell 4 for every detected temperature. The difference between a reference temperature determined by temperature sensor and the ambient temperature of load cell 4 is multiplied by the temperature coefficient of Young's modulus at Roberval part 15.  The product is registered as a temperature compensation sensitivity coefficient along with that for only the load cell 4 and a data is calculated while being corrected by these coefficients at the time of measurement.

Title: Blank holding construction of hydraulic press
Inventor: TAGUCHI MITSUO
IPC: B21D43/00
Filed: 1983-10-31
Abstract: PURPOSE:To improve working efficiency with small driving power by lowering a ram by the main piston of an upper frame cylinder, supporting the piston in the cylinder of the blank holder in the ram by an upper frame and performing pressing irrespectively of blank holding force. CONSTITUTION:A ram 27 is lowered by a piston 25 in the cylinder 24 of an upper frame 23. A piston 31 fitted into a cylinder 30 in a blank holder provided in the ram 27 is supported by an upper frame 23. The pressing force of the blank holder is therefore received by the upper frame and the pressing force of the piston 25 in the cylinder 24 is used only for the pressing operation. Since the blank holding force is not received by a main piston 25 unlike in the prior art, less driving power is required and cycle time is reduced by which productivity is improved.

Title: Device for preventing propagation of track potential of electric railroad
Inventor: GONDOU TOYOMI
IPC: B60M5/02
Filed: 1983-10-31
Abstract: PURPOSE:To prevent one section of a track from being affected by the short- circuiting of another section of the track, by insulating the sections of the track from each other as to corresponding substation power supply areas, and connecting a reactor in parallel between the insulated sections. CONSTITUTION:When a feeder 11 and a track section 13a are short-circuited to each other at a place 16, the potential on the track section 13a rises but the current suppressing action of a reactor 15 blocks the rising potential from being propagated to another track section 13b, so that the voltage at a second substation 12b does not increase. For that reason, the operation of a vehicle 17 moving on the track section 13b is not hindered at all but smoothly performed. Since the current through the vehicle in its normal operation flows as direct current through the reactor 15, the same current distribution as the case without the reactor is provided so that the operation is not impeded at all.

Title: Analytical method for phenol
Inventor: TOYAMA KENJI
IPC: C07C39/00
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To make a high-efficiency, high-accuracy analysis requiring an easy operation and not altering phenol by feeding a polar organic solvent aqueous solution with a specific concentration to a column in advance before it is concentrated. SOLUTION: When phenol is to be analyzed by an octadecyl silica gel-filled chromatographic column (ODS-filled column) by this analytical method for phenol, a polar organic solvent aqueous solution with a specific concentration specified according to the hydrophobic index is fed to the column in advance before a sample containing phenol is fed. The recovery percentage of an analytical object after fractionation by the ODS-filled column is sharply improved as compared with the conventional method, e.g. the level of about 95-100% can be sufficiently maintained against the reference quantity before the solution is fed to the ODS-filled column. The reason for the occurrence of this effect is considered that the column feature is changed to the state favorable to the concentration of phenol and phenol can be efficiently concentrated.
