Title: Method for measuring polyvinyl alcohol
Inventor: KISHIMOTO MAKIO
IPC: G01N33/26
Filed: 1990-11-29
Abstract: PURPOSE:To achieve a rapid and highly accurate measurement by performing measurement with the polyvinyl alcohol continuous analysis method of a degree of dispersion in a specific range. CONSTITUTION:A carrier containing boron and iodine within a carrier liquid well 1 is sent by a pump 2 and a polyvinyl alcohol sample is poured to this flow from a sample-pouring port 3 using a micro syringe. A sample reacts within a coil-shaped pipe 4 and shows a green and blue color. It is desirable that the coil-shaped pipe 4 should be provided within a constant-temperature bath 5. Then, by measuring the degree of absorption of light with a detector 6, a polyvinyl alcohol content is measured. An accurate measurement can be made when a degree of dispersion D of the sample is equal to or more than 5 and equal to or less than 80. Namely, when the degree of dispersion is equal to or less than 5, a reaction cannot advance sufficiently and color development strength cannot be obtained or the reaction advances while a mixture is not sufficient and a single peak cannot be obtained. On the other hand, when the degree of dispersion is equal to or more than 80, dilution of the sample advances excessively and a sufficient color development sensitivity cannot be obtained.

Title: Controlling method for body inclination of rolling stock
Inventor: ISHIHARA KOICHIRO
IPC: B61F5/22
Filed: 1994-12-26
Abstract: PURPOSE: To enhance riding comfort by calculating the rolling angular velocity of a truck based on the vertical displacement between the truck and a vehicle body, and feeding or discharging air to or from an air spring so that excess centrifugal acceleration anticipated from the time required for the truck rolling angular velocity to reach a maximum value and from the speed of travel is decreased. CONSTITUTION: When a railway vehicle enters a curved track and first passes through a transition curve area, a body 1 and a truck 2 supporting a wheel set 9 via a primary spring 8 cause an outer-rail side vertical displacement sensor 3 and an inner-rail side vertical displacement sensor 4 to fluctuate respectively in the direction of compression and in the direction of expansion as the body 1 is inclined toward the outer rail. Then the rolling angular velocity of the truck is calculated from the outputs of a gyro sensor 6 mounted on the body 1 and from those of the vertical displacement sensors 3, 4, and the radius and the cant of a circular curve to be entered thereafter are calculated on the basis of the value of the rolling angular velocity.  With the deviation of the current inclination angle from a desired inclination angle as a control output, feed and discharge valves are controlled for opening and closing so as to adjust the height of an air spring 7, thereby correcting the inclination of the body.
