Title: Static capacitance-to-voltage converter and converting method
Inventor: HIROSHIMA TATSUO
IPC: G06Q50/22
Filed: 1999-01-22

Abstract: A static capacitance-to-voltage converter is capable of converting a static capacitance into a voltage without suffering from a stray capacitance formed between a signal and a shielding line or a stray capacitance formed between an exposed portion of the signal line and its surroundings. The static capacitance-to-voltage converter is formed of an operational amplifier placed in an imaginary short-circuit state between an inverting input and a non-inverting input thereof; a signal line having one end connected to the inverting input and the other end capable of being connected to a static capacitance; a shielding line surrounding the signal line and connected to the non-inverting input; an alternate current signal generator for applying the non-inverting input with an alternate current signal; and zero adjusters for adjusting the output of the static capacitance-to-voltage converter to minimum when no static capacitance is connected to the signal line.

Title: Cryogenic processor for liquid feed preparation of a free-flowing frozen product and method for freezing liquid composition
Inventor: JONES CURT D
IPC: A23L3/375
Filed: 1999-04-26
Granted: 1999-12-11
Abstract: A cryogenic processor for liquid feed preparation of a free-flowing frozen product incorporates a gas diffusion chamber that inhibits freezing of a droplet producing feed assembly and pre-cools liquid droplets during the production of the free-flowing frozen product. This is accomplished by providing a regulated flow of ambient air about the feed assembly in conjunction with a vacuum assembly which is used to remove excess refrigerant vapor from the gas diffusion chamber. The vacuum assembly is incorporated into the gas diffusion chamber between the feed assembly and a freezing chamber. The gas diffusion chamber also provides additional physical separation between the feed assembly and the freezing chamber to allow for pre-cooling of the falling liquid composition droplets prior to contacting liquid refrigerant in the freezing chamber therebelow. Additionally, the shape of the processor has been adapted to reduce refrigerant requirements and improve overall production efficiency.

Title: Chip scale surface mount packages for semiconductor device and process of fabricating the same
Inventor: ZANDMAN FELIX
IPC: H01L23/31
Filed: 2000-01-07
Granted: 2001-06-23
Abstract: A package for a semiconductor device is formed by a process which includes forming a metal layer in contact with a connection pad on the front side of a semiconductor die while the die is still a part of a wafer. The metal layer extends into the scribe line between the die and an adjacent die. A nonconductive cap is attached to the front side of the wafer, and the wafer is ground from its back side to reduce its thickness. A cut is made from the back side of the wafer, preferably by sawing and etching, to expose the metal layer. A nonconductive layer is formed on the back side of the wafer and a second metal layer is deposited over the nonconductive layer, the second metal layer extending into the scribe line where it makes contact with the first metal layer through an opening in the nonconductive layer. Preferably, a solder post is formed on the second metal layer to allow the finished package to be mounted on a printed circuit board. The cap is then sawed along the scribe line with a saw whose kerf is small enough not to sever the contact between the metal layers. The dice are thereby completely detached from each other, forming individual semiconductor device packages.

Abstract: The invention of this machine tool wiper includes: installing unit 3, which is installed on the sliding surface 14, related to this machine, and wiper main body 10, which is made of elastic materials and integrally formed on the installing unit 3. The wiper main body 10 and blade 11 can slide on the sliding surface 14. At least lip part 11 of a wiper main body 10 is covered with fiber material 5.

Title: Method and arrangement for minimizing power dissipation in a line driver
Inventor: RANDAHL TORBJORN
IPC: H04L25/02
Filed: 2000-04-28
Granted: 2003-08-01
Abstract: To minimize power dissipation in a line driver (3) in a central office (CO) for driving a DSL connection to a network terminal (NT) with a predetermined maximum constellation size, the central office (CO) supplies the line driver (3) with a predetermined supply voltage during a training sequence, and transfers data with a predetermined power spectral density in all available channels. The network terminal (NT) measures the signal-to-noise ratio of each channel, and transfers information to the central office (CO) about channels having signal-to-noise ratios that enable transfer of data. The central office (CO) reduces the power spectral density to a lowest possible value that still enables transfer of data in all channels having signal-to-noise ratios above a predetermined threshold as set by the maximum constellation size, calculates a sum of power to be transmitted in said channels, converts said sum into a corresponding line driver output voltage, and reduces the line driver supply voltage in correspondence thereto.
