Title: Evaluating method for efflorescence generated at cement product
Inventor: AOYAGI MUTSUO
IPC: G01N33/38
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to simply measure the generation of efflorescence in a short time by using alcohol containing water solution of pH indicator exhibiting alkalinity. SOLUTION: The lower 1/2 part of a cement product in thickness direction is dipped, for example, in water to absorb water. The absorbed water is gradually moved to a surface layer which is not dipped in water. At this time, the alkali component in the product is moved to the surface layer with the absorbed water. When it is coated with a pH indicator having a color change area to the alkaline side to the alkali component such as pH indicator of thymol blue or phenol red, the color is exhibited in the color change area in response to the pH. The generation of efflorescence is predicted according to the degree of the coloring. Accordingly, the time up to a predetermined coloring area is measured to predict the easiness of generating the efflorescence in a short time.

IPC: B24B53/04
Filed: 1991-07-17
Abstract: PURPOSE:To provide a method of correcting a grinding wheel, which can enhance the degree of accuracy for the shape of a workpiece while improving the surface roughness, and which can prolong the service life of the grinding wheel. CONSTITUTION:A tapered part 2 in the front part and a straight part in the rear part of a grinding wheel 1 are roughly tooled, and then the straight part 3 are finely tooled.

Title: Multiplexed control system for input/output device
Inventor: TOYOSHIMA SATOSHI
IPC: G06F13/00
Filed: 1989-07-10
Abstract: PURPOSE:To reduce consideration for multiplex control based upon software and to contact the overhead of a system by allowing the DA of a specified I/O device of the subside to falsely coincide with the DA of the master side I/O device and making only an input bus significant. CONSTITUTION:When the selecting operation of the master side is executed by executing an instruction by an information processor (EDP), the data input bus of the subside is made significant by a subside switch having the same identification code (DA). Thereby, the subside received sequential data sent from the EDP to the master side to execute ordering simultaneously with the sending and the same operation is executed in both the master side and subside. Since plural I/O devices can simultaneously execute the same operation even when one I/O device executes an instruction, multiplex control can be attained. Since a large part of multiplex control is constituted of hardware and microcontrol, the consideration for multiplex control based upon software can be reduced and the system overhead can be suppressed to a minimum.
