Title: Device for photographing rotating body at breaking moment
Inventor: HIEI ATSUSHI
IPC: G01N21/84
Filed: 1992-11-05
Abstract: PURPOSE:To surely take the picture of a ceramic object to be inspected at the moment the object starts to break even when the ceramic object breaks without emitting a sufficient amount of light by arranging ceramic rings around the ceramic object at intervals. CONSTITUTION:Since ceramic guide rings 31 are arranged around a ceramic turbine wheel 1 which is a ceramic object to be inspected rotating at a high speed, the rings 31 are separated from the wheel 1 before the wheel 1 breaks. When the rotating speed of the wheel 1 exceeds the rotational strength of the wheel 1, the wheel 1 starts to break and the picture of the wheel 1 at the moment the wheel 1 starts to break is taken by utilizing a luminous phenomenon which occurs when the wheel 1 breaks. In case the wheel 1 has a large defect, the energy at the fracture becomes smaller and the luminous phenomenon becomes weaker, but, since the fragments of the wheel 1 momentarily collide with the rings 31, the rings 31 and fragments work as flints and are forcibly made to emit light. Therefore, the picture of the wheel 1 having a large defect at the moment the wheel 1 starts to break can be taken nearly similarly to a defectless wheel 1.

IPC: C30B29/16
Filed: 1986-12-12
Abstract: PURPOSE:To form a uniform film while preventing an abrupt reaction and to grow a metal oxide film small in leakage current in a vapor phase by using an organic compd. wherein both acyl radical and alkoxyl radical are coupled with same metal atom as a raw material. CONSTITUTION:The metal oxide film, namely a Ta2O3 film is grown in a vapor phase with the following method by using an organic compd. [i.e. Ta(OC2 H5)(OOCCH3)4] shown in a formula (R1O)w(R2)nM (R1 shows acyl radical, R2 shows alkoxyl radical and M shows metal atom respectively) as a raw material. In other words, the above-mentioned organic compd. is heated similarly to a conventional method to increase vapor pressure and gasified while bubbling it with carrier gas and transported to a reaction furnace, Ta(OC2H5)(OOCCH3)4 introduced into the furnace is thermally decomposed on the surface of a base plate arranged in the furnace. In this case, the temp. of the base plate is regulated to about 350-500 deg.C a little higher than the thermal decomposition temp. of the above-mentioned raw material. Since this thermal decomposition is advanced in two stages, the formation of the deposited film is slowly advanced in comparison with the conventional method and it is homogeneous in comparison therewith and the Ta2O3 film small in leakage current can be formed.
