Eight of Toshiba Imaging's ultra-compact IK-HR1S high-definition cameras were recently used to film a 60-second commercial of a living-room chair as it was carried into space by a helium balloon. The balloon flights were launched from a Nevada desert and ascended to 98,268ft (18.6miles) altitude before breaking apart and falling back to earth. The IK-HR1S cameras' compact size (1.75in x 1.75in x 3in) and the HD-SDI video output capability with switchable 1080i/720p scanning options made them suitable for this project. The custom-built camera rigging had Toshiba's miniature HD cameras attached to the frame. The lightweight apparatus, with a full-sized model chair made from biodegradable balsa wood, was less than 4lb. Also attached to the rigging frame were four GPS systems to record altitude (accuracy was within 4m), longitude and latitude, and to monitor, via a computer satellite system, the location of the camera rig once it had fallen back to earth. The high-definition f...

In vacuum circuit breakers or vacuum contactors, current making and breaking is performed in the entirely sealed vacuum chamber. So, they poses various features such as (1) Excellent arc-extinguishing ability, (2) Less contact wear, and long life, (3) Safety, no fire or explosion hazard, (4) Less maintenance, (5) Compact and lightweight. Then the vacuum circuit breakers and vacuum contactors have been becoming major switching apparatus throughout the countries around the world.In 1965, Toshiba put the first vacuum switching devices in the market. Since then, various efforts have been made to increase their application fields. Regarding switching surge, analysis of generating mechanisms, measurement of the switching surge, development of the surge suppressors have been achieved. Based on those results this application guide was compiled. Toshiba Low & Medium Voltage Vacuum Contactors are all "low surge type". As contactors are mainly applied for a motor switching, low s...
