Title: Tig arc spot welding device
Inventor: MIYAZAKI TOSHIAKI
IPC: B23K9/29
Filed: 1981-08-31
Abstract: PURPOSE:To facilitate welding of aluminum sheet materials of different thicknesses in a TIG arc spot welding device by projecting notched parts for discharging a shielding gas for welding on the inner side in the preceding end part of a gas cup. CONSTITUTION:When a welding signal is applied, a shielding gas ejects through the small hole 4a of a collet 4, flows along the inner side surface of a gas cup 15, and flows out through notched parts 15a to the outside. At the same time, an arc is generated between a tungsten electrode 3 and an aluminum sheet material 1. At this time, the sheet material 1 expands by the effect of heating and the part where the arc is generated tries to float up but the material 1 is pressed to an aluminum bar 2 by the projecting parts 15b of the cup 15. Therefore, the floating of the sheet 1 is suppressed, said material is melted to one body with the aluminum bar 2 by receiving the integrated thermal effect, whereby the welding is completed.

Title: Level sensor circuit
Inventor: ISHII JIYUN
IPC: H04B1/64
Filed: 1980-09-30
Abstract: PURPOSE: To improve dynamic characteristics such as overshoot by superposing the output signal of a logarithmic amplifier on a linear signal component.  
     CONSTITUTION: Signals supplied to input terminal 11 are fed to an amplifier 31 through an impedance circuit 12. The output of the amplifier 31 is fed to the base of a transistor 20 by passing through a rectifier circuit which consists of diodes 15 and 16 and an inverter 17. Diodes 32∼35 form a logarithmic amplifier together with the amplifier 31 and they are driven by an attenuator which consists of resistors R1 and R2. In this case, if input signal voltage e 1  becomes large, lowering of voltage caused by the resistor R1 becomes large and this voltage is superposed on a logarithmic waveform. Consequently, overshoot can be reduced.

Title: Antenna system
Inventor: INOUE MASATO
IPC: H01Q13/02
Filed: 1987-05-29
Abstract: PURPOSE:To attachably/detachably obtain an antenna system whose directivity fre quency characteristic is able to be decreased by assembling a cone taper and a directivity shaping concave lens to a radome incorporatedly and adopting a structure to be screwed to a circular waveguide of a horn antenna main body. CONSTITUTION:Denoting the mechanical size being a difference of path length of an aperture face B without a concave lens 3c as delta and the size of the concave lens 3c as (d), then the phase phi at the aperture ridge face B is retarded by equation I only (inverse of lambdag represents an integration mean value of a guide wavelength). In adding the concave lens 3c to the aperture, a new phase error DELTAphi (equation II) is added when a radio wave is transmitted therethrough, where lambda is a free space wavelength and epsilonv is a specific dielectric constant of the type of material of the concave lens. In mounting the concave lens 3c, the phase lag phi at the aperture ridge end face B with respect to the center is expressed as equations I+II=equation III, and the phase error is further increased with high frequencies in comparison with the equation I. The beam width is wider when the phase error is increased in the directivity of the horn antenna and the frequency characteristic value as to the directivity is decreased before the mounting in mounting the concave lens 3c.
