Title: Circular polarized wave generator
Inventor: ITANAMI TAKAO
IPC: H01P1/17
Filed: 1979-05-23
Abstract: PURPOSE:To make it possible to reduce the leakage of a transmitted signal to a received signal output terminal by generating a circular polarized wave by the use of two directional couplers with the degree of coupling of 0dB. CONSTITUTION:A transmitted input signal, branched to waveguides 16 and 17 after passing through waveguide 14, is coupled with circular waveguide 6. Then, this signal has components of planes A and B of polarization, which have a difference in phase of 90 deg. to generate a polarized wave. On the other hand, a received signal which is the reverse of the transmitted signal is input from terminal 7 and that having the component of plane A of polarization is coupled with rectangular waveguide 21 after passing through the directional coupler of 0dB in degree of coupling consisting of coupling elements 201 and 202. Then, the signal having the component of plane B of polarization is similarly led to rectangular waveguide 22 from coupling elements 203 and 204. The phase difference is eliminated by adequately setting lengths of both the waveguides and both the signals are mixed together by branch part 23 without a loss before being output 23. Thus, the leakage of the transmitted signal to the received signal terminal can be eliminated.

IPC: H01L29/84
Filed: 1981-04-24
Abstract: PURPOSE:To obtain surface density close to 2.0X10<18> at./cm<3> which is optimum to a pressure-senitive element, by diffusing impurities at a different temperature from that of drive-in addition to pre-deposition and drive-in to decrease the density of surface impurities of a piezo resistor. CONSTITUTION:When forming a piezo resistor by the diffusion of P type impurities on an N type Si substrate, temperature is set to 950 deg.C to diffuse impurities on the surface layer of the substrate to a limit for a solid solution. Next, drive-in is applied to the inside of the substrate to cause the secondary diffusion at temperature of 1,100 deg.C higher than that on pre-deposition in oxidation atmosphere simultaneously with the oxidation of the surface layer. Thereafter, temperature is decreased to 1,070 deg.C to heat for the density of surface impurities of a piezo resistor close to 2.0X10<18>at./cm<3>. Thus, the surface density is specified to obtain a pressure-sensitive element with small temperature dependency of output sensitivity.
