Abstract:
An in-situ compressed specimen of copper interconnection micro column, which is a circular metal column formed in a PDMS hole, includes: a specimen part and a fixed end part for fixing the specimen; wherein the fixed end part is a circular or square plate structure, the specimen part is an upper part of the fixed end part; a main body of the present invention is of micron order, a forced direction of the specimen is consistent with a growth direction of the metal column. A method of electroplating copper column by adopting PDMS as template substrate is applied to overcome a problem that TSV is corrosive to the copper column during a silicon etching process so as to affect a mechanical property accuracy test, the method is advanced in shortening test process period, achieving good reproducibility and high yield.
Abstract:
A four-stroke engine without a crankshaft and valves contains a base including a gas groove, a first cylinder, a second cylinder, two gas flowing holes, a first inlet, a first outlet, and a holder; a gas valve including a connecting rod, a second inlet, and a second outlet; a driving device including two pushing posts, a rotating arm, a rotary shaft; a gear set including a panel, an upper gear, and a bottom gear, wherein the drive gear has a second tilted bar, the second tilted bar has a second opening arranged thereon, a second rotatable bearing; a seat including a peripheral side coupling with a top rim of the holder, a fixed pole axially connecting with the holder and the base; wherein a top end of the rotary shaft extends out of the seat.
Abstract:
A four-cylinder four-stroke engine contains a base, a gas valve, a holder, a driving device, and a driven assembly, and a seat. When a four-cylinder four-stroke engine operates, a plurality of cylinders push plural pistons in the plurality of cylinders of the driving device so as to drive plural pushing posts connecting with the plural pistons to move upward and downward repeatedly, such that the driven assembly coupling with the plural pushing posts is pushed to drive a rotary shaft to rotate, thus generating a rotational energy, and the driven assembly simultaneously pushes a gear set of the driving device so that the gear set drives the gas valve on the base to rotate 360 degrees to feed and exhaust gases in the base, such that the plurality of cylinders are driven to feed, compress, burst, and exhaust gases continuously without using a crankshaft and valves.

Abstract:
This invention provides a plastic frame to be a separated device so as to combine the lower metal cover, wherein the plastic frame has two extend shafts that are covered with two wrap-sides beside the lower metal cover. Furthermore, the packaged structure of the present invention can effectively apply the elastic-press method by at least one seam on the principal part of the plastic frame to fix two metal covers and the plastic frame. Moreover, the packaged structure of the present invention has a plurality of convexes in at least one seam on the principal part and the ends of two extend shafts of the plastic frame to press and combine two metal covers.
