Title: Magnetic recording medium for rotary encoder
Inventor: TODA HIROMITSU
IPC: G01D5/245
Filed: 1988-09-02
Abstract: PURPOSE:To easily magnetize a magnetic recording medium by forming a groove in parallel to a cylindrical shaft in an outer periphery of said medium and magnetizing said medium in a loop form along said outer periphery. CONSTITUTION:A magnetic recording medium 1 is formed of a hard magnetic material into a hollow cylindrical shape. Grooves 2 are engraved at equal intervals in an outer peripheral surface of the medium 1. When the medium 1 is to be magnetized, a cable 3 is passed through the axial center of the medium 1 to which is added a direct current. Consequently, a looped magnetic flux phiis formed within the medium 1, with a leak magnetic flux phim produced outside the grooves 2. Accordingly, if a rotary shaft is mounted in the medium 1 and a magnetic sensor 4 is fitted facing the outer peripheral surface of the medium 1 to detect the magnetic flux phim, the rotating angle of the rotary shaft can be detected based on an output of the sensor 4.

Filed: 1994-09-14
Abstract: PURPOSE: To more suitably and reliably alarm over bank wave by calculating current data for over bank wave decision while using the measured data of plural sensors for measurement, and comparing the calculated data for tidal wave decision with threshold data in a storage means. CONSTITUTION: A measured data transmitting means 11 converts signals from the respective sensors for waveheight, wind velocity, wind direction, tide level and rainfall to digital data, synthesizes those data into serial data and transfers them to a decision control means 14. The decision control means 14 converts the data transferred from the measured data transmitting means 11 to data (z) for over bank wave decision to evaluate whether it gets over the bank or not. First of all, the decision control means 14 calculates current data zo for over bank wave decision and compares them with threshold data (z) in a storage means 13. In the case of zo>z, an over bank wave alarm signal is outputted to an alarm control means 17. In the case of zo<z, predicted data zt for over bank wave decision after the lapse of time T are compared with the threshold data (z).  In the case of zt>z, an over bank wave predictive alarm signal is outputted to the alarmans 17.

Title: Method for measuring moisture content of fresh concrete
Inventor: NAKAMURA HIROYUKI
IPC: G01N9/36
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To measure the moisture content of concrete directly, simply and rapidly. SOLUTION: Concrete 10 is housed in a container and a hydrophobic liquid 14 not dissolved in water and having specific gravity larger than that of water is injected in the container. Centrifugal force is applied to the mixture of concrete 10 and the liquid 14 to separate the mixture into a solid and a liquid. Moisture W that is the lowest in specific gravity rises to the upper part of the container because the action of centrifugal force becomes minimum. The particle interstices of the cement (c) and aggregates S in concrete 10 are filled with the liquid 14 of which the specific gravity is larger than that of water to prevent separated moisture W from returning to the particle interstices of the cement (c) and the aggregate S.  In this state, the high (h) of the surface of the moisture W separated on the liquid 14 of which the specific gravity is larger than that of water is measured. Since the inner area (s) of the container is known, when the height (h) of the surface of the moisture W is measured, the volume and mass of the moisture W are found.
