Patent JP-H06201621-A (JP)
Title: Heat analyzer
Inventor: NAKAJIMA HIROMICHI
IPC: G01N25/16
Filed: 1992-12-30
Abstract: PURPOSE:To accurately correct by a simple operation. CONSTITUTION:A sample having a known thermal expansion amount is measured by a mechanocaloric analyzer to obtain a measured value Lo(T) at that time. If the theoretical elongation of the sample is Lst(T), the correcting amount (Lsys(T) + Lb) is obtained by subtracting Lo(T) from the Lst(T), and its value is stored as correcting data of each temperature in overall expansion measurement correction data memory means 10. When a sample in which thermal expansion amount is unknown is measured, correcting value of each temperature of correcting data (Lsys(T)-Lb) stored in the means 10 is added to the data Lo(T) by data correcting means 12, and a true thermal expansion amount Lst(T) of the sample is obtained.

Title: Digital protective relay
Inventor: FURUSE MITSUYASU
IPC: H02H3/02
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain a digital protective relay, capable of preventing erroneous relaying operations caused by an attenuating DC constituent that remains after a current is shut, when a current or zero-phase voltage is detected by a current transformer. SOLUTION: An AC current of a system to be protected is detected by a current transformer CT1, and these detection signals are converted into digital data through an analog filter AF and an A/D converter. These data rows are filter calculated by a digital filter DF and a DC constituent detecting part SD is provided to perform protection calculation at an effective value calculating part from the filter output. In the detecting part SD, a discriminating part COM discriminates the polarity of the output data rows of the digital filter, and counter timers TP, TN determines whether or not the same positive or negative polarity continues for a certain period of time. If the polarity continues for that period, it considers that a residual DC constituent exists so that the effective value at an effective value computing part EV is cleared to zero by an OR circuit 'OR'.

An area of a plan of the open ceiling parts is formed to be slightly larger than trunk diameters of the trees, and trimming of branches is done when a branch grows from the trunk part so that the trunk part only passes through the open ceiling parts. Moreover, banking is done on the rooftop R to plant plants having shallow roots in order to form a rooftop park due to tree planting effect on the rooftop simultaneously. A green tract of land where big trees and plants grow is provided in a place where buildings are clustered close together without an allowance of a site without requiring great costs.  Consequently, tree planting in a city part can be promoted by a simple configuration.
