Title: Metallic thin film for pattern formation and production of patterned metallic thin film
Inventor: FURUICHI HIROSHI
IPC: C23F1/00
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To improve the productivity in the patterning of a metallic thin film and to form the edge part of an orderly taper by subjecting a metallic thin film formed on a substrate to ozone exposure or cleaning with an aq. soln. of potassium hydroxide and converting it to the hydrophilic one in such a manner that the surface thereof and water make a specified contact angle. SOLUTION: On a substrate 11 such as glass or the like, a metallic thin film 12 of aluminum, chromium or the like is formed to a thickness of about 1500 to 4000 Åby a vapor deposition method or the like. This metallic thin film 12 is subjected to ozone exposure and/or cleaning with an aq. soln. of potassium hydroxide and is made into the hydrophilic one in such a manner that the contact angle between the surface thereof and water is controlled to <35 degrees, preferably about <=30 degrees. The surface of this hydrophilic metallic thin film 12 is applied with a photoresist composed of a resin to a thickness of about 0.05 to 15 μm to form a resist pattern 13 by photomechanical processing technology. Then, this is etched with an etching soln.  In this way, the etching soln. infiltrates from the end part of the resist pattern 13 to make the edge part of the metallic thin film 12 to an orderly taper to prevent the cutting of the difference in level (edge) in the film 14.

Title: Acoustic emission measuring apparatus
Inventor: SAKUMA SHUICHI
IPC: G01N29/14
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To efficiently measure an acoustic emission(AE) signal by preliminarily investigating the measurable max. AE event ratio and changing an AE threshold value when the AE event ratio enters a specific ratio. SOLUTION: The AE wave generated from a test object is converted to an electric signal by a sensor 1 and this signal is amplified by a preamplifier 2 and a main amplifier 3. When the AE signal detected by an envelop detector 6 exceeds the AE threshold level set by an AE threshold setting device 7, the AE signal is judged by a signal processing part 4 and, at the same time, an event pulse is outputted. The AE signal advances to an output/display part 5 through a parameter extraction part 8 and an operation part 11. By this constitution, the AE peak value of the AE signal is generated on a wide level and, at the same time, even when the AE signal such that the AE event ratio is largely changed is measured, an AE measuring apparatus is put to practical use up to a measuring capacity limit to efficiently measure AE.
