Title: Both corner edge chamfering method for plate material and its device
Inventor: HOSOGAI NOBUKAZU
IPC: B24B9/00
Filed: 1994-06-27
Abstract: PURPOSE:To excellently chamfer and polish both corner edge faces by providing a machining contact pressure between the both corner edges of a plate material and a rotary grinding wheel by means of a balance plumb bob body. CONSTITUTION:A plate material G as an object to be machined is held in a holding rotary mechanism 5 so as to be vertically rotated at a low speed, while a supporting member 4 is allowed to be lowered oscillatingly without any strain by means of an upward/downward moving mechanism 29, so that both corer edges F, F of the plate material G are brought into pressure contact with a pair of rotary grinding wheels T, T rotating at a high speed. Machining contact pressures between both of the corner edges F, F of the plate material G and inclined machining surfaces T1, T2 of the rotary grinding wheels T, T are balanced by means of a balance weight body 27. As no strain is applied to the supporting member 4, the supporting member 4 is oscillated vertically according to a change in a distance from the center of rotation to the corner edge F in the plate material G while the plate material G is brought into contact with the rotary grinding wheel T so as to be rotated, and in this way, chamfering is carried out. Therefore, both corner edges F, F are continuously and excellently chamfered.

Abstract: PURPOSE:To form a quantum thin wire by exposing a multiple quantum well structure by selecting the growing conditions of a selective epi-mask to a surface orientation of the substrate so as to form a step on the cross-sectional plane of a multilayer film. CONSTITUTION:An SiO2 selective epi-mask 5 (insulating film) is formed on a semiconductor substrate 4 and also a multiple quantum well structure 1 is formed through a first semiconductor layer 2. At this time, a surface orientation of the substrate 4 is approximately <100>, and that of the stripe-form epi-mask 5 is <011>. By selecting the growing conditions, a step having a (111)B plane as its side plane is formed on a crosssectional plane of the multilayer film which has been crystal-grown. The side plane of a well structure 1 which is exposed on said step by a selective epitaxial growth is subjected to the selective etching by utilizing a difference in crystal composition of the semiconductor layer forming the side plane of the well structure 1. Thus, a groove is formed on the side plane of the well structure 1 and the semiconductor for forming a quantum thin wire 6 is grown on the semiconductor wafer 2 so as to fill said groove. Furthermore, a forth semiconductor layer 8 covers the whole of the side plane of step and the quantum thin wire 6 can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide excellent high-speed operating characteristic even in a normal operation by independently latching respective logic input signals in general operation and in scan test by a master latch part, and selectively outputting them by a slave latch part. SOLUTION: A general logic input master latch part 1 and a scan test logic input master latch 2 are independently provided in parallel, and both master latch part outputs are outputted through a common slave latch part 3.
