Inventor: MIURA HIDEO
IPC: G01N17/04
Filed: 1989-02-27
Abstract: PURPOSE:To continuously inspect water quality over a long period of time while using a single test piece installed in a reactor vessel by detecting the change in the water quality from a change in the electrostatic capacity between electrodes by corrosion of the surfaces of the electrodes disposed to face each other.

Title: Ion exchange treatment of glass material
Inventor: KAITE RYOICHI
IPC: C03C21/00
Filed: 1987-02-26
Abstract: PURPOSE:To enable ion exchange treatment at high temp. without generating the deformation of a glass material by releasing one end of the glass material in a medium contg. monovalent cations or in gas in case of ion-exchanging both monovalent cations incorporated in the glass material and monovalent cations incorporated in the medium via a porous material. CONSTITUTION:Glass 1 as a base material is introduced into a space 2A of a vessel 2 for holding the base material which consists of a rigid porous material provided with communicated pores, and the holding vessel 2 is immersed into medium 3 incorporating monovalent cations. After the melting medium 3 is infiltrated into the communicated pores of the holding vessel 2, it is brought into contact with the surface of glass 1 and ion exchange is performed between monovalent cations incorporated in the melted medium 3 and monovalent cations incorporated in glass 1. Therein since one end of glass 1 to be treated is released in the medium 3 (or in gas), stress generated by thermal expansion and contraction of glass 1 is absorbed in this released face. Further bubbles incorporated in the porous material 2 can be easily removed by properly evacuating it. Therefore the time for ion exchange treatment can be shortened without generating the deformation and a recess of glass even if the temp. of ion exchange is raised.

CONSTITUTION:Nearly W-shaped track width control grooves 5 are worked in gap formation surface of a couple of substrate 1 of ferrite with high magnetic permeability and an amorphous alloy magnetic film 7 with high saturated magnetic flux density is adhered to each surface. Then, a nonmagnetic material 8 is charged and then the entire gap formation surface is polished. Then, a nonmagnetic material 9 mads of SiO2 for control gap length is sputtered and adhered to the entire gap formation surface and the gap formation surfaces of the couple of ferrite substrates 1 are heated above the softening point of glass in an abutting state and held for a specific time to form a gap. Consequently, the nonmagnetic materials serve not only to prevent dust from being deposited, but also as an adhesive material for a back core, so only the nonmagnetic material 9 for gap length control is only adhered during the gap formation, thereby reducing the complexity of the manufacturing process and mass-production.
