Fabrication of Dish-Shaped Micro Parts by Laser Indirect Shocking Compound Process

open access: yesMicromachines, 2016
Compound process technology has been investigated for many years on a macro scale, but only a few studies can be found on a micro scale due to the difficulties in tool manufacturing, parts transporting and punch-die alignment.

Effect of the individual layer thickness and relative blanking clearance on micro-blanking for Cu/Nb multilayer composite sheets [PDF]

open access: yesMATEC Web of Conferences
In this study, two types of Cu/Nb multilayer composite sheets with individual layer thicknesses of 11.11 μm and 0.35 μm, respectively, were first prepared and then tested by micro-blanking.

Galling-Free Fine Blanking of Titanium Plates Using Carbon-Supersaturated High-Speed Steel Punch

open access: yesC, 2023
A carbon-supersaturated (CS-) high-speed steel punch was prepared using low-temperature plasma carburizing for fine blanking of pure titanium plates. The bare high-speed steel punch was also prepared as a reference to describe the adhesion and abrasive ...

Demonstration of wavelength packet switched radio-over-fiber system [PDF]

open access: yes, 2007
The authors present a novel concept of employing optical wavelength packet switching in radio-over-fiber access networks. In such a system, the tunable laser (TL) would be employed as a transmitter in the central station. The optical carrier generated by

Comparison of Lifetime of the PVD Coatings in Laboratory Dynamic Impact Test and Industrial Fine Blanking Process

open access: yesMaterials, 2020
Protective hard PVD coatings are used to improve the endurance of the tools exposed to repeated impact load, e.g., fine blanking punches. During the fine blanking process, a coated punch repeatedly impacts sheet metal.

Fast Spectrometry System with Using Tunable Laser Diode [PDF]

open access: yes, 1980
Basic prohlems are discussed about a local, realtime and very sensitive air-pollution monitoring using a laser diode. The method employs the second derivative spectrometry replacing the incoherent light source and mechanical choppers in a traditional ...

DESIGN AND SAFETY FACTOR SIMULATION OF AN AUTOMATED FEEDER FOR BLANKING MACHINES

open access: yesMedia Mesin
The displacement of the stainless-steel plate to the printing work area is still managed manually by the operator. Additionally, there is no clear benchmark to determine whether the plate is in the correct position and aligned according to the printed ...

The neural correlates of “mind blanking”: When the mind goes away

open access: yesHuman Brain Mapping, 2019
Mind blanking (MB) is the state where our minds are seemingly “nowhere,” and attention calls no perceptual input into conscious awareness. It is little investigated, perhaps partly because it is difficult to detect the mysterious periods of blanking.

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

open access: yesMolecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.
