Title: Method for working thickness-finish of fragile material
Inventor: MORITO HIDEKAZU
IPC: B24B27/06
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To reduce cracks, chippings and the like, and improve dimensional accuracy by elevating the matter to be worked while feeding abrasive grains, permitting wires to travel by work rollers with a straight wire wound with a tension balanced by a weight, and cutting and finishing the matter to be worked. SOLUTION: On each work roller 1 grooved at a groove pitch of 0.70mm a straight wire 3 of a steel wire is wound around, and a constant tension is held by a weight 2. As a variation of the finished size is great at the feeding side and recovery side of the wire 3, a pitch correction is preferably conducted by allowing for an abrasion rate of the wire. The wire 3 is fed at a constant speed, and the work rollers 1 and wire 3 are put into normal rotation and reverse rotation simultaneously at the constant speed. Next, by feeding abrasive grains and elevating the matter to be worked 4a, work is implemented for a dimensional finish of the cut thickness. As a result, since the thickness dimension is finished only by cutting work, surface grinding work is not required and side curvature is not generated.

Abstract: PURPOSE:To enable the uniform distribution of abrasive grains by adjusting either one of the stability of a complex in plating bath, the concentration of hydrogen ion in plating bath. bath temperature, and current density in electrolysis in order to adjust the gas generating efficiency of hydrogen gas generated during electrolysis. CONSTITUTION:With attention given to reaction generated at the surface of a base metal 2 forming a negative electrode during electrolysis, that is, plating forming reaction and hydrogen gas generating reaction, the degree of hydrogen gas generating efficiency is adjusted so as to adjust the detaching degree of abrasive grains P1-P9 and eventually to adjust the quantity of abrasive grains fixed to the base metal 2. The grade of the hydrogen gas generating reaction is determined by the composition of bath in electrolysis and an electrolytic condition. As the composition of bath, the structure of metal ion and the concentration of hydrogen ion are important, and as the electrolytic condition, the bath temperature and current density are important. To be concrete, the hydrogen gas generating reaction becomes predominant as the structure of metal ion in bath is a more stable complex.

Filed: 1985-03-25
Abstract: PURPOSE:To obtain an end surface position with high precision by forming a groove in a specific pattern in the surface of a substrate outside the focal position of a lens previously and then measuring the distance between two grooves appearing in a cut and polished end surface. CONSTITUTION:Grooves 6 and 7 are formed outside and concentrically with focus positions 14 and 15 of a collimator lens 3 and a converging lens 5 at specific distances from those focus positions 14 and 15. Consequently, a light incidence end surface and a light end surface 9 are easily which coincide with the focus positions 14 and 15 of the collimator lens 3 and converging lens 5. Namely, when a substrate 1 is cut, the tangential position of the grooves 6 and 7 are cut at a specific angle and polishing is carried out by the distance between the predetermined focus positions and grooves. As the end surface is polished, the end surface of the groove separates into two and their distance increases gradually. The distance between the grooves is measured to know the quantity of polishing from the groove positions accurately.
