You write a ruby program like this:

require 'mechanize'
agent = Mechanize.new
agent.user_agent = 'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)'
url = 'http://www.tele.soumu.go.jp/musen/SearchServlet?SK=2&DC=100&SC=1&pageID=3&CONFIRM=0&SelectID=1&SelectOW=01'
page = agent.get(url)

File.foreach('a1cc.txt') do | t |
  print t.chomp << " "
  next_page = page.form_with(:name => 'select_condition') do |form|
    form.MA = t.chomp
  end.submit
  puts next_page.css('form[name="result"] td')[8].text.gsub(/[\n\t]/,"")
end

And you will get:

% ruby mechanize.rb
