Title: Salinometer
Inventor: NAGATA TAKESHI
IPC: G01N27/06
Filed: 2001-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a salinometer in which the salinity of an object can be measured accurately not only under low temperature but also under high temperature. SOLUTION: In the salinometer for measuring the salinity of an object A by detecting the electrical conductivity thereof by means of a salinity sensor 13, two sensor terminals 15a and 15b constituting the salinity sensor 13 are projecting stepwise from the forward end part of a holder 14. Even when the object A boils to develop a very high temperature, generated bubbles B do not strand between the sensor terminals 15a and 15b. Since the outer surface area of the sensor terminals 15a and 15b is prevented from varying by preventing adhesion of bubbles B to the outer surface of the sensor terminals 15a and 15b at all times, electrical conductivity of the object A can be detected accurately and thereby the salinity can be measured accurately.

Filed: 2001-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a grinding method with excellent abrasion resistance of a cutting blade, enabling smooth and efficient grinding when grinding a workpiece with rotary disk cutting blades for grinding. SOLUTION: A disk 15 for grinding is rotated while vibrating radially, and moved relatively to a workpiece 30 fed at desired feeding speed. Cutting blades 15a in a plurality of lines formed at an outer peripheral surface of the disk for grinding are intermittently brought into contact with the surface of the workpiece by the vibration to polish the workpiece.

In this case, a wave length of the sinusoidal shaped trace of each cutting blade is set to be shorter than a contact grinding distance defined as a distance L at which the fed workpiece and the disk for grinding are contacted to carry out the grinding.  Thereby, portions in which the cutting blade does not contact the workpiece are produced and grinding of the workpiece by the cutting blade, consequently, are carried out intermittently.
