Inventor: TAWARA HIROSHI
IPC: B01D53/34
Filed: 1998-07-02
Granted: 2001-10-21
Abstract: A process for processing a waste gas containing gaseous hydrocarbons and recovering the hydrocarbons as a liquid using a pair of adsorption apparatuses containing an adsorbent layer filled therein for performing adsorption and waste gas containing 1000 ppm to 2 VOL% of gaseous hydrocarbons to pass through one of the adsorption apparatuses at ambient temperature and at a pressure of 0.03 to atom 1 atm to cause gaseous hydrocarbons to be adsorbed in the adsorbent layer in the adsorption apparatus and discharging waste gas containing less than 100 ppm gaseous hydrocarbons into atmosphere, meanwhile operating the another adsorption apparatus at ambient temperature and at a pressure up to 100 mmHg to desorb the gaseous hydrocarbons which was adsorbed in the adsorbent layer in the second adsorption apparatus by suction using vacuum pump as well as by feeding a purge gas and cooling the purged exhaust gas to recover the gaseous hydrocarbons as a liquid, wherein the total amount of the purge exhaust gas containing uncondensed hydrocarbons after cooling is returned to the first adsorption apparatus through which the waste gas is allowed to pass thereby increasing the hydrocarbon concentration in the adsorbent layer in said first adsorption apparatus and switching the adsorption operation to desorption operation before the adsorbent layer is broken-through, the switching time between the adsorption and desorption operations being 5 to 30 minutes.

Title: Power unit for motorcycle
Inventor: MATSUTO TAKUSHI
IPC: B62M7/02
Filed: 1998-08-01
Granted: 2000-04-11
Abstract: The invention provides a power unit less affected by the length of a cylinder of an engine. To achieve this, a cam shaft drive mechanism 120 composed of a cam shaft drive pulley 121, a belt 122, a pair of cam shaft pulleys 123 and 124, and a tensioner 125 is disposed on the front surface of a power unit 15. Since the cylinder is disposed in the width direction of the vehicular body with its cylinder axis 126substantially in the horizontal direction (for example, a tilt angle <alpha> with respect to the ground is set at +10 DEG), the center of gravity of the vehicle is lowered and also the cylinder length can be set within the vehicular width. This increases the constructional freedom of the vehicle.

Granted: 2001-10-21
Abstract: A dynamic random access memory device includes sub-word line drivers to drive sub-word lines up to a boosted voltage level. Each sub-word line driver generates a sub-word drive signal to drive a corresponding sub-word line in response to a main-word decode signal and a sub-word decode signal. Each of the sub-word line drivers includes an N-channel MOS pull-up transistor and an N-channel MOS precharge transistor whose threshold voltages are different from each other. The conduction path of the pull-up transistor is coupled between the sub-word decode signal and the corresponding sub-word line. The precharge transistor has a conduction path coupled between the main-word line and the control electrode of the pull-up transistor. The control electrode of the precharge transistor is coupled to the boosted voltage. The boosted voltage is larger than the power supply voltage by twice the threshold voltage of the pull-up transistor. The threshold voltage of the precharge transistor is smaller than that of the pull-up transistor.

Granted: 2002-06-11
Abstract: The specification describes IC devices with arrays of solder ball interconnections in which the balls are reshaped to produce flattened surfaces to improve contact of the array with a test or interconnection substrate. Techniques described to flatten the balls include cutting away the surface of the balls using a dicing saw.

The reshaped balls are especially well suited for testing with a sockets test bed. In a preferred embodiment the sockets are formed by pairs of intersecting V-grooves, whereby pyramid shaped features are produced at the bottom of each socket. The sharp points of the pyramid(s) provides contact enhancement between the flattened solder bumps and the test bed. The sockets of the test bed can be provided with through holes to interconnect the solder bumps to the next board level with minimum electrical path length thereby reducing parasitic capacitive coupling.
