Title: Aluminum alloy sheet having superior formability
Inventor: IMANAKA MAKOTO
IPC: C22C21/06
Filed: 1992-01-27
Abstract: PURPOSE:To improve the sliding characteristics of the surface and to improve the press formability of an Al-Mg alloy sheet by specifying the average roughness of surface ruggedness of an Al-Mg alloy sheet, the average value of the spaces between the recessed parts, respectively. CONSTITUTION:In an Al-Mg alloy sheet containing 4-10wt.% Al and having >=25% elongation, the average roughness Ra of the surface ruggedness, the average value Lv of the spaces Lvi between the recessed parts represented by equation I (where n means an integer >=2), and the regularity parameter S showing the regularity of the surface roughness and represented by equation II are regulated so that, at least with respect to one direction of the Al alloy sheet surface, they satisfy the following conditions, respectively: 0.5mum<=Ra<=3.0mum; 50mum<=Lv<=500mum; S<=0.20. Because the Al-Mg alloy sheet having such surface conditions has superior sliding characteristics, press formability affected by sliding characteristics can remarkably be improved. Moreover, the press formability of this Al-Mg alloy sheet can be improved to a greater extent by forming a iron-group plating layer or a solid lubricant layer on the surface by 1-20g/m<2>.

Filed: 1986-01-24
Abstract: PURPOSE:To realize a semiconductor-laser wavelength stabilizer having a highly stable oscillation frequency even for a mount by providing a predetermined modulation means, an absorption cell, a photodetector, a lock-in amplifier and a control means. CONSTITUTION:Output beams from a semiconductor laser LD1 are separated in two directions by a beam splitter BS1, and beams having frequency upsilon+fD are projected to an absorption cell CL1 as primary diffracted beams at the time of ON of a SW1. Incident beams are all projected to the absorption cell CL1 at frequency upsilon0 as O-order diffracted beams at the time of OFF of the switch SW1. When beams modulated by an acoustooptic modulator UM1 are projected to the absorption cell CL1, the amount of transmitted beams is modulated and a signal appears in an output. When the signal is converted into an electric signal by a photodetector PD1 and rectified synchronously at frequency fm in a lock-in amplifier LA1, a primary differential waveform is acquired. When the currents of the semiconductor laser LD1 are controlled by a PID controller CT2 and an output from the lock-in amplifier LA1 is locked (controlled) at the center of said primary differential waveform, output beams form the semiconductor laser have stable frequency of upsilons-fD/2.

Title: Working device
Inventor: SENSEI MUNEHIRO
IPC: B23Q35/00
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To easily perform prescribed work on a work having an optional shape by providing a pressing means to always press a working tool unit to the work by constant pressing force and a guide means to advance/retreat the whole working tool unit by copying after an external shape of the work. SOLUTION: A guide roller 49 comes into contact with an outer cylinder part of a work 5, and functions so as to copy after its external shape according to rotation of the work 5. That is, it copys after its shape while properly advancing/retreating in the horizontal direction according to a change in the external shape of the work 5. A chamfering cutter 47 also synchronously advances/retreats according to operation of a guide roller 49. In that case, pressing force to the work 5 is held constant by a pressing means. Therefore, even if the external shape of the work 5 changes, since it is always brought into pressure contact with its outer peripheral edge part by constant pressing force, chamfering work can be performed in a constant chamfering quantity.
