Die (integrated circuit)

A die in the context of integrated circuits is a small block of semiconducting material, on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die.

There are three commonly used plural forms: dice, dies, and die.

Die (manufacturing)

A die is a specialized tool used in manufacturing industries to cut or shape material mostly using a press. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology.

Die forming

Forming dies are typically made by tool and die makers and put into production after mounting into a press. The die is a metal block that is used for forming materials like sheet metal and plastic. For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers (called blister packs) for merchandise. Vacuum forming is considered a simple molding thermoforming process but uses the same principles as die forming. For the forming of sheet metal, such as automobile body parts, two parts may be used: one, called the punch, performs the stretching, bending, and/or blanking operation, while another part, called the die block, securely clamps the workpiece and provides similar stretching, bending, and/or blanking operation. The workpiece may pass through several stages using different tools or operations to obtain the final form. In the case of an automotive component there will usually be a shearing operation after the main forming is done and then additional crimping or rolling operations to ensure that all sharp edges are hidden and to add rigidity to the panel.

Crow (horse)

Crow (23 February 1973–10 February 1989) was a French Thoroughbred racehorse and sire. He was one of the best three-year-olds in Europe in 1976 when he won the classic St Leger Stakes and finished second in the Prix de l'Arc de Triomphe. He went on to win the Coronation Cup as a five-year-old in 1978. After his retirement from racing he stood as a breeding stallion in the United States and Australia with limited success.

Background

Crow was a chestnut horse with a white blaze standing 16 hands high bred by his owner Daniel Wildenstein. He was the best horse sired by the Prix de l'Arc de Triomphe winner Exbury, to whom he bore a close physical resemblance. His dam, Carmosina was an Argentinian mare bought by Wildenstein for $10,000. The colt was sent into training in France with Angel Penna. Crow usually raced in a sheepskin noseband.

Racing career

1976: three-year-old season

Crow did not race as a two-year-old but began his racing career in the spring of 1976. He won the Prix Northeast, finished second to Hunza Dancer in the Grand Prix de Compiegne and then won the Prix Eugene Adam over 2000 metres at Saint-Cloud Racecourse.

Crow (Sioux leader)

Crow was a Sioux chief who gave the opening battle cry at the Battle of the Little Big Horn.

Crows are a licorice candy identical in shape and texture to Dots.

History

Crows were invented in the 1890s by confectioners Henrique Cataldi and Joseph Maison. The Black Crows trademark was registered in 1911. There is an urban legend that Crows were to be called "Black Rose," but the printer misheard the name as "Black Crows" and printed wrappers with the wrong name on them. This myth has been debunked.

In 1972, Tootsie Roll Industries acquired the Crows brand by purchasing Mason Division from Candy Corporation of America. Crows were featured on Red Bar Radio.
