A marker on the sidewalk in Palo Alto, Ca.just north of El Camino on San Antonio Road notes that being the site where Dr. Shokley(sp) and associates invented the transistor. A dozen or so blocks north on San Antonio at Charleston there is a building with a monument at the door noting that "At this site Dr Robert Noyce and associates at Fairchild invented the first practical application of the integrated circuit." That would have been the Planar Process and the whole Silicon Valley evolved from that. JK |

Hardly since the Germans didnt actually do any work in this area. The Germans's fell far behind the allies in terms of electronics and electronic warfare as the war progressed. They fell behined in the high frequency field. In other areas they reamained on par. The transistor came out of work done at Bell Labs that began in 1939 by Russel Ohl and the IC was invented at Texa Instruments by Jack Kilby. Noyce (of intel fame) invented it simultaneously. The Tranistor is credited to William Schokley. An Englishman who received the Noble prize leading the team that developed it. I admire Schokely's political views incidently. The Germans were using a sort of rubberised ironball for u-boat snorkels and conning towers. Screens were also carried on board u-boats that could be errected around the conning tower. Finaly the Go 229 was to recieve a sort of carbon black based 3-ply skin that had RAM properties and the aircraft showed use of re enterant structures. Surely opperation paperclip must have made use of some of this or been aware of German approaches to the issue. Hardly , the german countermeasures were almost entirely ineffective since they were working on the assumption that allied radars were operating in the metre band rather than the centimetric radar that was actually being used. Ugh! This misapprehension lasted for less than 1 year and ended by 1943. The German had succesfully used simple radar as early as 1935 to detect ships up to 1km away. They however had to use minature valves that had outputs limited to a watt at most. Either way they were aware of what was being used against them and succesfully put into service countermeaures such as warning devices and homing devices. German pre war doctrine held that radar or radio emisions would reveal one to the enemy and empphsised passive techniques and this may have influenced their neglect at maintaining their lead in radar. It has to be rememberd that Randle and Boots magnetron was developed because they wanted a cheap radar emiter for the detector and direction finder they were developing. That would be Randall and Boot who developed the cavity magnetron at Birmingham University in 1940. Because they couldn't afford the klystrons that were around at the time for their radia direction finding work. The Germans also developed active radar systems and Telefunken had been working on just such a device as early as 1935 but had been unable to get even close to the efficiencies and power levels that Randall and Boot achieved. Yep, the power levels were around 50W but apparently stable. To low to give a radar more than 1km range. The Japanese appear to have beaten Randall and Boot but the value of their device was not recognised. If they had of been given a bigger budget they may not have stumbelled upon it. As far as Germans inventing the integrated circuit goes? Well that never happened but it might have because an ex Luftwaffe technician may actualy have invented a transistor. It's quite a sad story actualy: http://home.t-online.de/home/Benduhn/summary.htm What it describes is interesting but its not a transistor but a cold cathode tube and that was first demonstrated by Philo Taylor Farnsworth II in 1934 Good try: From you own link. "The performance of this new type of tube depends upon the emission of secondary electrons from two cathodes which are bombarded with high-velocity primary electrons. " Clearly your cold cathod tube requirs a high tension power supply. Its entirly possible that your ex Luftwaffe technician was aware if it since an article in Radio by Arthur Halloran described it in detail in the issue published in October 1934. http://www.borderlands.com/archives/arch/multipact.htm Denk would have been a 18 year old kid. Or he may have just come across it himself as claimed: To make a transistor 1 Dope Germanium or Silicon lightly as P type material. This is the base of the transistor. 2 Press 2 tungsten pins into the above base and pass a current. This will form n-type regions at the point contacts. That is a pont contact tranistor and it was the first type to enter production. Making selenium rectifiers and crystal radio 'cats whisker' rectifiers relied on a similar process at the time. The claim that the first tubeless radio was built in 1948 is so wrong its farcical. The crystal set was common in the 1920's. You're spliting hairs again. Why are you compelled to do that? Clearly the claim is that he developed some sort of amplification that did not require heated cathodes or valves. It's not inconceivable that he stumbelled across some sort of solid state effect perhaps due to the odd metals used in valves of the time and followed up on it. His desire to retain the benefit for his people entirely is understandable if misguided. The lot of a Sudeten German (Actualy Austrian prior to that Bavarian) was miserable before and after the War. ****** You make a mistake when you call me pro-German. I have had similar claims in realation to me being pro-serbian, pro ukranian, pro english and pro-russian. I for instance found myself disgusted by the British act of supporting the Turks against Russians who were trying to defend Bulgaria during the Crimean war. British participation in WW1 was an act of collosal stupididy and WW2 doubled that. If German involvement on behalf of Austria in WW1 was stupid then Bristish Involvement was mendanciouly stupid as the people of the UK were manouvered into war by upper class ****s pumping out lies and faked atrocity rumors. Sadly things in the UK haven't changed and the English in particular are suffering for it. |
