Title: Interference wave eliminating device
Inventor: TSUJIMOTO ICHIRO
IPC: H04L27/38
Filed: 1990-05-31
Abstract: PURPOSE:To effectively eliminate both of the multipath distortion and an interference wave by extracting an interference component without filtering on the frequency base by subtraction of a desired signal replica from a reception signal and subtracting this interference component from the reception signal after phase control to eliminate the interference wave. CONSTITUTION:A discrimination feedback equalizer 2 eliminates the multipath distortion included in a matched signal outputted from a matching filter 1 to generate a discrimination signal, and a convoluter 3 convolutes an inference impulse response and the discrimination signal to obtain a designated desired signal. A delay element 6 fixedly delays the reception signal, and a subtractor 8 takes the difference between the output signal of this element 6 and the designated desired signal to extract the interference wave component. A power detector 9 detects the power of the difference signal inputted to the matching filter 1, and a designated interference wave generator 5 controls the phase of the interference wave component to generate a designated interference wave so that the power detected by the power detector 9 is minimum. Thus, both of the multipath distortion and the interference wave are effectively eliminated.

Title: Surface burner
Inventor: NISHINO TOYOJI
IPC: F23D14/16
Filed: 1986-06-17
Abstract: PURPOSE:To provide a surface burner which is not liable to be damaged in porous body by making the length of the minimum flow passage from the outlet of fuel gas feed conduit to the outlet of oxigen-rich gas feed conduit greater than that which can prevent the reverse flow of the gases due to the differential pressure between them. CONSTITUTION:When the differential pressure is small between the feed pressure of the two gases P1, P2 and the atmosphere pressure P3, and the differential pressure between the two gases P1, P2 is greater, the gases do not smoothly flow from the side to the outside due to the flow resistance of gas in a porous body 3, and, as a result, the gases may flow backward from either one of the feed conduits 5 or 6 to either one of the other conduits 6 or 5 in the area near a separator 8. By raising the flow resistance of that area by filling a filler 10 to the outlet 5a of the high-pressure side feed conduit 5, and making the length of the minimum flow passage of gas between the two feed conduits 5 and 6, the differential pressure of gas in the feed conduit 5 or 6 can be absorbed, preventing the flow of the oxigen-rich fuel gas into the fuel gas feed conduit 5 or the flow of the fuel gas into the oxigen-rich gas feed conduit 6.

Abstract: PURPOSE: To eliminate a danger of an electric shock by connecting one end of a series main feedback circuit including an end of an output winding of an oscillating transformer to a closed loop comprising a collector and emitter of an npn-type transistor, a battery, a power-suppy switch, and an input winding of the oscillator transformer.  
     CONSTITUTION: A closed loop is constituted by a collector and emitter of an npn- type oscillating transistor (Tr)Q, a battery E, a power-supply switch S, an input winding L p  of an oscillating transformer T f . A main feedback circuit is constituted by an output winding L s  of the transformer, a switching and rectifying element R e , a capacitor M c , and a base and emitter of the TrQ. A forward direction bias is applied to the TrQ by a base bias resistor R through a feedback winding L f . A base capacitor C and a winding L f  constitute an auxiliary feedback loop. In this constitution, since the potential difference between a can case (negative side) and the battery E comprises only a pulse voltage generated during the operation, an electric shock can be eliminated even though a human body touches the can and the battery at the same time.
