Title: Laser beam machine
Inventor: OSANAI HAJIME
IPC: B23K26/382
Filed: 1988-12-19
Abstract: PURPOSE:To prevent waste of auxiliary gas required for working by detecting whether a laser light is reflected by the surface of an object to be worked or not by a high speed photoelectric element, ending the piercing working at the time point when a reflection of a monitor of its detecting signal is gone, and shifting to the cutting working. CONSTITUTION:By a common of an NC device 1, a laser light 3 outputted from a laser oscillator 2 is split into a working use lase light 3b and a detection use laser light 3c by a beam splitter 6a. The laser light 3c is made incident on an integrating sphere 14 and controls an output of the laser oscillator. The laser light 3b starts working of an object 8 to be worked and a part of a reflected light 13 transmits through the beam splitter 6a and detected by a high speed photoelectric element 20, and a signal for showing a fact that a reflected light 13a exists is outputted to a piercing monitor device 21. When a hole is allowed to pass through the object to be worked, a reflected light is gone, therefore, a signal for showing a fact that there is no reflected light is outputted, and immediately, working is shifted to cutting working by a command from the NC device.

Filed: 1988-12-23
Abstract: PURPOSE:To prevent needless feeding of a continuous form paper from occurring by setting a supervising time, and driving a cutting means to cut the continuous form paper when conditions for the next recording are not satisfied after a predetermined recording paper operation and before the supervising time expires. CONSTITUTION:When recording data comes to be absent, a predetermined supervising time (e.g. 3sec) is set. Next, it is judged whether recording data to be recorded next is not prepared within the supervising time. When the next recording data is not prepared within the time, a movable blade 12 is driven by a cutting-controlling means 27 to cut a continuous form paper 1. Thereafter, it is judged whether the trailing end of the paper 1 thus cut is fed past an electrostatic recording part 3. This judgement is made by judging whether the paper 1 comes to be absent at a position opposed to a discharge detecting sensor 16. Driving of the recording part 3, rotation of a feeding driving roller 7 and rotation of a discharging driving roller 14 are stopped, whereby the whole operation is stopped.

Abstract: PURPOSE:To purify crystals to high purity by only washing with water by allowing a slurry consisting of crystals of aimed metal complex, back-extracting liquid, and a solvent to stand, separating a crystal phase obtd. as the lowermost layer, and washing then obtd. crystals with a washing liquid. CONSTITUTION:Crystals of aimed metal complex are separated from a slurry consisting of crystal of aimed metal complex [e.g. (NH4)3FeF6] obtd. from a reverse extraction stage in a solvent extraction process, reverse extracting liquid (e.g. aq. soln. of NH4HF2), and an org. solvent (e.g. di-2-ethylhexyl phosphate + n-paraffin), and separated crystals are purified. In this stage, the slurry is separated into three passes: an uppermost org. solvent phase, a liquid phase contg. a small amt. of the org. solvent suspended in the reverse extracting liquid comprising an intermediate phase, and a lowermost crystal phase consisting of the aimed crystals of the metal complex and the reverse extracting liquid. The lowermost crystal phase is subjected to solid/liquid separation, and obtd. crystals are washed with washing liquid. Thus, the crystals are purified to high purity by only washing with water without washing with an org. solvent.
