dynatron การใช้

• In 1936, the company name was changed to Dynatron Radio Ltd.
• In 1981, Roberts Radio bought Dynatron from Philips.
• In 1981, Philips sold Dynatron to Roberts Radio.
• In the dynatron a tetrode tube is used.
• During this time, Dynatron was moved from Maidenhead to King's Lynn.
• As in the dynatron oscillator the control grid can be used to adjust the negative resistance.
• Despite this, the Dansette brand outsold other makes such as Dynatron, Ferguson and others.
• A suppressor grid is also called the antidynatron grid, as it helps to reduce the dynatron effect.
• Since the transitron oscillator didn't depend on secondary emission it was far more reliable than the dynatron.
• IVA . The first examples arrived in January 1941, with more units from ADEE and Dynatron following in early February.
• In the dynatron and transitron circuits, a vacuum tube is biased so that one of its electrodes has negative differential resistance.
• Both Rebecca II and Eureka II were developed by Murphy Radio with early pre-production of Rebecca II by Dynatron Radio.
• In the 1918 issue of the Proceedings of the IRE he published a paper on the dynatron vacuum tube which he had invented.
• He invented the dynatron vacuum tube which had three electrodes : a thermionic cathode, a perforated anode, and a supplementary anode or plate.
• An exception to this are models from certain manufacturers which have become collectable such as Hacker Radio Ltd ., Dynatron, Blaupunkt, SABA.
• The firm began in a room above the family grocery shop in Maidenhead High Street, and the first product emerged in 1928; the Dynatron U53 radiogram.
• The Dynatron range had always been aimed at the top of the market, but achieving this in post-war times was always going to be problematic.
• The negative resistance operating region of the tetrode is exploited in the dynatron oscillator, which is an example of a negative resistance oscillator . ( Eastman, p431)
• During the Second World War, Dynatron contributed to the war effort on a not for profit basis, expanding the work force from around 70 employees to 160.
• Ekco bought the Dynatron business in 1954 and the Ferranti brown goods brand in 1957 ( though not Ferranti's heavy industries, defence electronics or meter businesses ).
