Fuse (electrical)

In electronics and electrical engineering, a fuse (from the French fusée, Italian fuso, "spindle") is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, interrupting the circuit that it connects. Short circuits, overloading, mismatched loads, or device failure are the prime reasons for excessive current. Fuses can be alternative to circuit breakers.

A fuse interrupts an excessive current so that further damage by overheating or fire is prevented. Wiring regulations often define a maximum fuse current rating for particular circuits. Overcurrent protection devices are essential in electrical systems to limit threats to human life and property damage. The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Slow blow fuses are designed to allow harmless short term currents over their rating while still interrupting a sustained overload. Fuses are manufactured in a wide range of current and voltage ratings to protect wiring systems and electrical equipment. Self-resetting fuses automatically restore the circuit after the overload has cleared, and are useful in environments where a human replacing a blown fuse would be difficult or impossible, for example in aerospace or nuclear applications.

Fuse (hydraulic)

In hydraulic systems, a fuse (or velocity fuse) is a component which prevents the sudden loss of hydraulic fluid pressure. It is a safety feature, designed to allow systems to continue operating, or at least to not fail catastrophically, in the event of a system breach. It does this by stopping or greatly restricting the flow of hydraulic fluid through itself if the flow exceeds a threshold.

The term "fuse" is used here in analogy with electrical fuses which perform a similar function.

Hydraulic systems rely on high pressures (usually over 7000 kPa) to work properly. If a hydraulic system loses fluid pressure, (burst hydraulic hose) it will become inoperative and components such as actuators may collapse. This is an undesirable condition in life-critical systems such as aircraft or heavy machinery particularly forklifts. Hydraulic fuses help guard against catastrophic failure of a hydraulic system (for instance, by line breakage or component failure) by automatically isolating the defective branch.

Sigh (band)

Sigh (サイ, sai) is a Japanese extreme metal band from Tokyo, formed in 1989. They are credited as being one of the first Japanese black metal bands, when the majority of black metal in early 1990s came from Scandinavia. They gradually shifted from a more traditional black/thrash metal sound, to a more experimental, avant-garde style.

Biography

Sigh was founded in 1989 in Tokyo, Japan. The band was signed by Euronymous' (of Mayhem fame) infamous label Deathlike Silence Records and released their first full-length album Scorn Defeat on DSP in 1993, shortly after Euronymous' death. The label ceased to exist shortly after his death and Sigh changed to Cacophonous Records.

After major disputes with Cacophonous over promotion and album rights, the band eventually found a new home at Century Media Records. Through this label they released their album Imaginary Sonicscape in 2001, which contained a more avant-garde elements than their previous work. In 2005 they released their full-length Gallows Gallery through yet another source, Candlelight/Baphomet Records. The band then signed to The End Records that released Hangman's Hymn and Scenes From Hell and reissued re-mastered versions of Gallows Gallery and Imaginary Sonicscape with revamped artwork and bonus tracks, before re-signing with Candlelight Records. After returning to Candlelight Records, Sigh has released 2012's In Somniphobia, and have announced recordings for their 10th studio album, Graveward, will begin in mid-2014.

Sigh (film)

Sigh is a 2000 Chinese drama film directed by Feng Xiaogang, written by Wang Shuo, starring Zhang Guoli, Liu Bei, Xu Fan and Fu Biao. Like most of Feng's films, the film is set mostly in Beijing.

Plot

Liang Yazhou (Zhang) is a successful, middle-aged TV screenwriter from Beijing. While in Hainan working on a new script, Liu Dawei (Fu) assigns young and beautiful Li Xiaodan (Liu) to him as an assistant. Yazhou and Xiaodan are mutually attracted to each other, but Yazhou is already married to Song Xiaoying (Xu), with whom he has a daughter. To break off the connection, he changes his plans and returns to Beijing. However, as soon as Yazhou and Xiaoying return to Beijing, they begin having an affair.

When Xiaoying finds out about Yazhou's affair, she is furious and initially demands a divorce. Relations between Yazhou and Xiaoying become extremely strained. They separate, and Xiaoying eventually accepts Yazhou's affair for the sake of their young daughter Yueyue. Despite Xiaoying's tolerance, Yazhou remains caught between the two women, on one hand being spoiled by Xiaodan and, on the other, being an attentive father in front of Xiaoying and Yueyue. Even with Xiaodan demanding marriage, Yazhou finds himself unable to divorce his wife, due to the harmful impact their separation has already had on Yueyue.
