Title: Combining lost foam and sand core casting technology
Inventor: GLIGOR CORNELLU I
IPC: B22C9/22
Filed: 2000-03-17
Abstract: A method of casting a workpiece having internal cavities uses a combination of sand core and lost foam techniques. A core of bonded granular material in the desired configuration of the voids of the workpiece is formed. The core has oppositely facing first and second surfaces with a pattern of channels extending between them. The pattern of the channels is in the desired configuration of walls for the cavities of workpiece. A first foam layer of destructible material is preformed and secured to the first surface of the core overlying one side of the channels. A second foam layer of destructible material is preformed and secured to the second surface of the core, overlying an opposite side of the channels. The assembly is placed in a refractory mold cavity, and granular refractory material is packed around the assembly. Molten metal is poured into the mold cavity into contact with the first and second foam layers, which decompose, causing the molten metal to flow into the channels, forming metal walls for the workpiece in the channels and in the spaces previously occupied by the foam layers.

Title: Measuring drying time of printing composition
Inventor: SOTO BRAULIO
IPC: B41J11/00
Filed: 2000-04-06
Abstract: A printing composition drying time detection system and method which can be used by e.g. a printing device (<B>Fig. 1</B>) includes a source (<B>92</B>), a sensor (<B>100</B>) and a controller (<B>139 in fig. 3</B>). The source transmits a first light signal (<B>96</B>) towards a quantity of printing composition (<B>98, 104, 106, 108, 110, 112</B>) such as ink, deposited on a print medium (<B>90</B>). The sensor detects a second light signal (<B>102</B>) reflected by the composition, this signal having a magnitude that decreases to a substantially constant value as the composition dries over a period of time. The controller receives an electrical signal from the sensor over this period, and determines a drying time for the composition.

Title: Writing to SRAM with column clear
Inventor: NAFFZIGLER SAMUEL D
IPC: G11C8/16
Filed: 2002-04-18
Abstract: An SRAM that has a column clear function with only three vertical lines and six total lines across a cell and a method of operating that cell and an array of those cells. Instead of two bit lines per port and two access devices per port as in a traditional SRAM cell, one bit line and one access device per port is used. In addition, one additional bit line, one additional word line, and two devices in series are used to perform the column clear operation and complete a write operation. The cell is operated by performing write operations using a two step process. To perform a write, each cell in a row to be written is preset to "1" during a first step. Then, each cell that is to have a zero written to it is cleared using the additional bit line and additional word line to address the cells to be cleared. A column of cells may be cleared by enabling all the rows for clearing, then asserting column clear control signals for each of the columns in the array to be cleared.
