Inventor: YAMASHITA MICHIO
IPC: B21C37/08
Filed: 1999-11-01

Abstract: In a pipe forming process using bending rolls, load applied to an upper roll is reduced to suppress the deflection of the upper roll, thereby suppressing creation of large end gap at the longitudinal center of the pipe, thus enabling production of high-strength, thick-walled elongated pipes. This is achieved either by (1) setting the roll spacing L between lower rolls to a value greater than the sum of the diameter Dwu of the upper roll 34 and the diameter Dw1 of each of the lower rolls 32, and setting the amount S of tightening of the upper roll 34 with respect to the lower rolls 32 to a value greater than the radius Rw1 of each of the plural rolls; or by (2) effecting pipe forming work on the sheet material such that the spacing L of the lower rolls 32 satisfies the following condition: (Dp+Dw1) > L ≥ 0.85 (Dp+Dw1), where Dp represents the outside diameter of the product pipe and Dw1 represents the diameter of one of the plural rolls; or by (3) preparing the sheet material having leading and trailing bent end regions bent beforehand over a length not smaller than 1/5 of the entire circumference of the pipe to be produced; and effecting bending by the bending rolls such that the length of the regions bent by the bending rolls is less than 3/5 the entire circumference of the pipe.

Title: Spray drying apparatus, secondary drying apparatus and methods of making particles
Inventor: CHICKERING DONALD E
IPC: B01D1/18
Filed: 2000-07-13
Granted: 2003-09-21
Abstract: Improved spray drying apparatus, and methods of use thereof, have been developed. The spray drying equipment includes a primary drying chamber and a secondary drying apparatus which includes tubing having a length sufficient to increase the contact time between the drying gas and the droplets/particles to dry the particles to the extent desired, at a drying rate and temperature which would be too low to provide adequate drying without the secondary drying apparatus. The secondary drying apparatus increases the drying efficiency of the spray dryer system without increasing the drying rate, while minimizing loss in yield. The ratio of the length of tubing to the length of the primary drying chamber is at least 2:1. The tubing diameter is substantially smaller than the diameter of the primary drying chamber, such that the particles move at higher velocity through the tubing to minimize product losses. The ratio of the cross-sectional area of the primary drying chamber to the cross-sectional area of the tubing most preferably is about 16:1. The tubing preferably is in a compact coil design, which can more easily be transported and which has minimum space requirements, and may optionally include a jacket to control the temperature of the secondary drying process. A preferred application for the spray drying process and equipment is in the production of microparticles, between about 1 and 200 mum in diameter, which can be used to deliver therapeutic and diagnostic agents.

Title: Fractal heat sink sheet and the shape generation method thereof
Inventor: CHEN JAU-JANG
IPC: H05K7/20
Filed: 2000-10-24
Granted: 2003-12-01
Abstract: The purpose of the present invention is to apply Carpet's Lacunarity fractal theory to create a novel heat sink sheet, which can be applied in the CPU of notebook computer, and be matched with a fan for enforcing air cooling. By applying the equations developed by the fractal theory, the density in the unit space can be determined to avoid the increased cost to guess the geometry of heat sink sheet by using try-and-error method, so as to achieve the purpose of heat dissipation for notebook computer. The result of the present invention shows that the leaf shape of the 2nd order fractal needle-like heat sink sheet is rectangular or circular, whose CPU temperature is lower than 80 DEG C as regulated by Intel. In addition, its horizontal inlet/outlet makes its average temperature of CPU lower than that of the vertical inlet/outlet for about 2.15 to 2.19 DEG C. The air circulation of circular leaf shape is better than that of the rectangular shape, since the secondary circulation phenomenon is less, and its heat dissipation effect will be enhanced.
