Patent JP-H02271702-A (JP)
Title: Horn antenna
Inventor: TAKAHASHI AKIRA
IPC: H01P1/16
Filed: 1989-04-12
Abstract: PURPOSE:To obtain a beam symmetrical with respect to the axis over a wide frequency band and an excellent cross polarized wave characteristic while simplifying the structure sufficiently by forming a dielectric film to an antenna inner wall made of a connector with a resistor film inbetween. CONSTITUTION:A resistance film 12 is coated to the entire inner wall of a conical horn antenna 11 made of a conductor and a dielectric film 13 is coated onto the film 12. Through the structure above, although tangential components Etheta, Ez of an electric field of the antenna 11 are zero, those of the magnetic field components Htheta, Hz exist. A current flows to the circumferential direction of an aperture of the antenna in the presence of the component Hz. In this case, since the film 12 is provided to the antenna 11, a potential difference is produced and an electric field Etheta in the circumferential direction is induced. Thus, the film thickness of the film 12 is selected properly and the resistance is set to cause the relation of Etheta Htheta. Thus, the beam width of the E and H planes is made equal and a circularly polarized wave generator is added to improve the cross polarized wave characteristic.

Title: Compressed-gas-sealed electric device
Inventor: UCHIMURA KAZUHIKO
IPC: H02G5/06
Filed: 1989-04-12
Abstract: PURPOSE:To simplify the monitoring by operating a pressure regulating valve to communicate two spaces when a predetermined pressure difference is caused two spaces and by holding the pressure difference between them within the predetermined limits. CONSTITUTION:When the force (F0) caused by the gas pressure difference between the 1st space and the 2nd space 2 becomes greater than the force (F1) of a coil spring 30, a releasing valve 23 is pushed downwards, so that two air vents 22 and 27 are communicated and insulating gas will flow into the 2nd space 2 from the 1st space 1. As a result, when F0<F1, the releasing valve 23 is pushed upwards by the coil spring 30 and the interval between the 1st and 2nd air vents 22 and 27 is interrupted. Thus the difference of gas pressure between the 1st and 2nd spaces 1 and 2 is settled within the predetermined limits. The monitoring can thereby be simplified because the gas pressure in those two spaces can be monitored by a single gas monitoring device.

When a seed material that flows in the fluid together passes by a crossing point 24, the reflected light containing the Doppler signal issued when detecting the laser light 22 comes, through the window 17, into the mirror 11, and then is reflected and condensed on the photo-detection part 14. The light is introduced into a photomultiplier, and, through photoelectric conversion, comes into a signal process device, so that flow rate at the crossing point 24 is calculated. Alternately, by moving an outside tube 10 in the direction of axis and an inside tube 15 in the direction of axis accordingly, for the position of crossing point 24 to be changed in two-dimensional manner, flow rate may be measured.

Title: Bonding fine wire for semiconductor
Inventor: SHIGA SHIYOUJI
IPC: H01L23/49
Filed: 1984-05-10
Abstract: PURPOSE:To obtain bonding fine wirings having excellent corrosion resistance and waterproofness by forming a Zn-containing layer on the surface layer of Au, Pd or Al or their alloy wire. CONSTITUTION:Zn is coated on the surface of Al, Au, Pd or their alloy wire by plating, depositing or sputtering. After Zn is coated by an arbitrary method on a thick wire as a method having high productivity, the wire is elongated to the final diameter. In this case, since Zn is diffused and alloyed by machining heat, the quality is frequently excellent. Corrosion preventive effect can be effectively performed with 0.7wt% or higher of Zn and particularly low density of 1-4%, thereby eliminating the influence to a bonding such as alloying or diffusion defect by the heat at the bonding time.
