At the PC design stage, heat flow analysis in a PC is needed. However, due to the complex printed wiring board structure, a large number of grids are required to enable precise calculation, ruling out calculations using a conventional PC. This has led to attempts to predict the temperature of an actual package by calculation based on a simplified package whose result is then modified. In this study, a compact casing and a package model are used to simulate actual notebook PCs. The performance of a diode package is experimentally obtained, and the flow inside the casing and the thermal performance of the package are studied with an obstacle placed inside the casing. This study is also conducted by aiming at acquisition of benchmark test data for CFD simulations.

Enhancing the cooling to spread heat in the process of the material cutting and milling has positive effect on increasing the efficiency of cutting and milling and assuring the apparent mass of test sample cut and milled. Basing on the experiment about the mixture of fixed pressure, fixed air and different quantity of water atomizing jet cooling the Ti alloy, this article discusses performance and regulation of phase transformation heat—transfer of simulating grinding Ti alloy forced air cooling by the mixture of fixed pressure, fixed air and little water.

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
