Filed: 1982-04-16
Abstract: PURPOSE:To increase the maximum measuring distance with a greater S/N ratio by adding reflected signals from a target of a pulse laser beam frequency. CONSTITUTION:After converted with an A/D converter 12, a reflected pulse signal an(t) of the nth transmitted pulse laser beam is increased by a constant (p) times with a multiplier 14 and inputted into one terminal of an adder 15 while the results of the addition up to n-1th operation stored in a memory 16 are increased by 1-p times with a multiplier 17 and inputted into the other terminals thereof and the output 18 of the adder provides a signal Sn(t). When the reflected pulse signals are all equally represented by a(t) because of no noise, the signal Sn(t) converges to an(t). The output of the adder gives a weighted addition average of data in the past and the noise is reduced as a result of the averaging operation due to lack of correlation. The reflected pulse signal having correlation converges to the reflected pulse signal without noise to elevate the signal-to-noise ratio thereby increasing the maximum measuring distance.

Title: Manufacture of low pressure mercury discharge lamp
Inventor: HASHIHATA MICHIHARU
IPC: H01J9/395
Filed: 1984-03-31
Abstract: PURPOSE:To shorten the time required for aging by encapsulating amalgam while splitting into plural particles into a light emission tube thereby quickening emission of mercury from the amalgam. CONSTITUTION:Amalgam 19 is encapsulated into a light emission tube 8 while splitting into many particles 19'.... Consequently, said particles 19' are dispersed widely into said tube 8 to substantially increase the surface area for the volume of amalgam 19.
