Title: Heat exchanger
Inventor: KIYOTELU TAKAYASU
IPC: B21D53/02
Filed: 1980-08-30
Granted: 1981-06-07
Abstract: A heat exchanger comprises a number of pipes(2) through which heat exchange is to be effected and end plates(1) in which the pipes are mounted.  It is manufactured by inserting each end portion of the pipes into holes bored in the end plates and then subjecting the peripheries of the end plates to produce plastic deformation of the end plates sufficient to make a fluid-tight seal between the pipes and holes.  In an example exchanger made withstood a pressure of 20 kg/cm2 without any leakage.

Abstract: The memory cell is constructed of a capacitor for storing charges, and a switching MOS transistor. The drain of the switching transistor is connected to a bit line, and the gate is connected to a word line. In operation, the signal charges stored in the capacitor are read out by means of the switching transistor. In constructing an actual memory of bits, a memory array is configured. A so-called "open-bit line" configuration is provided in which bit lines are arrayed on both the sides of a sense amplifier for differentially deriving a signal. Only one bit line electrically intersects a single word line, and the difference between the signals of the bit lines is detected by the sense amplifier.

Abstract: The modulator is suitable to the double phase modulation type communication especially when the band is limited but high  output power is requested. The modulator includes a  delay  circuit  (10) for delaying the PN code signal for a certain time, a wave shaping filter for shaping the delayed PN code signal and PN  code  signal to limit the pass band of signals, a  local  oscillator  (40)  for generating oscillating signal having a certain frequency,  a  phse changer (50) for changing the phase of oscillating  signal  for  a certain degree, a mixer for mixing output  signals  of  the  local oscillator (40), and the phase changer (50), and output signal  of the wave shaping filter respectively, and an adder (80) for adding two mixed signals fransmitted from the mixer to  output  modulated signal.
