Type 88 Surface-to-Ship Missile

The Type 88 Surface-to-Ship Missile (88式地対艦誘導弾, SSM-1) is a truck-mounted anti-ship missile developed by Japan's Mitsubishi Heavy Industries in the late 1980s. It is a land-based version of the air-launched Type 80 (ASM-1) missile; in turn it was developed into the ship-launched Type 90 (SSM-1B) missile. The Japan Ground Self-Defense Force bought 54transporter erector launchers, each carrying six Type 88 missiles, for use as coastal batteries. With a range of 180 km (97 nmi), high subsonic speed and 225 kg (496 lb) warhead, it is similar to the US Harpoon missile.

Overview

The basic configuration composes the same launcher vehicles and loader vehicles (6 SSM-1), some radar vehicles, fire control systems, and a command control system.

Usually, the SSM-1 is launched from within 100 km (62 mi) of the coast.

Ultrasonic motor

An ultrasonic motor is a type of electric motor powered by the ultrasonic vibration of a component, the stator, placed against another component, the rotor or slider depending on the scheme of operation (rotation or linear translation). Ultrasonic motors differ from piezoelectric actuators in several ways, though both typically use some form of piezoelectric material, most often lead zirconate titanate and occasionally lithium niobate or other single-crystal materials. The most obvious difference is the use of resonance to amplify the vibration of the stator in contact with the rotor in ultrasonic motors. Ultrasonic motors also offer arbitrarily large rotation or sliding distances, while piezoelectric actuators are limited by the static strain that may be induced in the piezoelectric element.

One common application of ultrasonic motors is in camera lenses where they are used to move lens elements as part of the auto-focus system. Ultrasonic motors replace the noisier and often slower micro-motor in this application.

Dinosaur

Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, 231.4 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the start of the Jurassic (about 200 million years ago) until the end of the Cretaceous (66 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the end of the Mesozoic Era. Until the late 20th century, all groups were believed to be extinct; however, the fossil record indicates that birds are modern feathered dinosaurs, having evolved from theropod ancestors during the Jurassic Period. As such, birds were the only dinosaurs to survive the mass extinction event.

Dinosaur!

Dinosaur! is an American television documentary about dinosaurs. It was first broadcast in the United States on November 5, 1985, on CBS. Directed by Robert Guenette and written by Steven Paul Mark, Dinosaur! was hosted by the American actor Christopher Reeve, who some years before had played the leading role of Superman.

In 1991, another documentary, also entitled Dinosaur! though not related, was hosted on A&E by the CBS anchorman Walter Cronkite.

Content

Jointly with Reeve's narration, the documentary shows special effects scenes which reconstruct dinosaurs and their era, along with interviews with the most famous paleontologists at the time of the documentary shooting, including Jack Horner, Robert Bakker, Phil Currie and Dale Russell. After a short introductory sequence and the subsequent opening credits the show starts with the mating of Edmontosaurus (identified as Hadrosaurus). The female soon lays a clutch of eggs that are eaten by a Struthiomimus, except for one. When the Struthiomimus eats the last egg it stole, it is then hunted and killed by a pair of Deinonychus. The remaining Edmontosaurus egg hatches and grows into a juvenile. While it is out grazing with its parents, it wanders off and is almost killed by a Tyrannosaurus, but the father hears its cries and comes to the rescue. While the mother looks after the juvenile, the father faces the Tyrannosaurus and knocks it over with his strong, 2,000-pound tail. Once down, the Tyrannosaurus could not get up easily, so the herbivore is given a chance to escape.
