Title: Feedthrough suppression reception circuit
Inventor: NISHIMURA SHIGEYUKI
IPC: G01S7/285
Filed: 1994-03-29
Abstract: PURPOSE:To prevent a reference signal which is leaked and appears at the output of a vector modulator part from entering a receiver when feedthrough level is small, in a feedthrough suppression reception circuit of a CW radar device. CONSTITUTION:A power divider 19 is provided at a signal reception input line and one output is input to a reverse-phase adder 6 and at the same time, the other is input to a feedthrough level detection circuit 17, thus detecting the feedthrough level. When the level is smaller than a preset level, a feedthrough suppression loop switch 18 is opened to prevent the output of a vector modulator part 5 from entering the reverse-phase adder 6 and hence the leakage reference signal from entering the reverse-phase adder 6, thus preventing a target detection capability from deteriorating due to the reference signal of leakage when the feedthrough level is small.

Filed: 1979-06-30
Abstract: PURPOSE: To enhance the thermal efficiency of the entire part by heating paper by an auxiliary fixing device and heating a toner by a main fixing device using a xenon flash lamp.  
     CONSTITUTION: Paper 9 having been transferred with the toner image of a photoreceptor 1 by a transfer device 4 is pressed to an auxiliary fixing device 11 consisting of heating elements and is further heated by a xenon lamp 12b positioned in a reflecting mirror 12a.

Abstract: PURPOSE:To reduce stress, which is applied to the edge of a chip, and to improve the reliability of a structure, by using a leadframe, in which, at least parts of the periphery of a die pad corresponding to the four corners of a semiconductor chip are bent to the side of the semiconductor chip. CONSTITUTION:A semiconductor chip 1 is bonded on a die pad 2 by, e.g., an Au-Si crystal. Lead terminals 3a and 3b are connected by bonding wires 4a and 4b made of Au. The device is put in a metal mold and molded as a unitary body by using epoxy resin. At this time, a leadframe, which is formed by blanking a sheet of metal plate, is used. A bending die pad 6, whose periphery is bent to the side of the semiconductor chip 1, is used. When stress distribution after the resin sealing is observed through a fringe pattern caused by optical elasticity, which appears at the periphery of the semiconductor element, the more the number of fringes, the more the stress is concentrated. Therefore, it is found that the stress applied on the chip surface is alleviated. Thus the stress applied on the edge part is reduced, the defective rate is reduced, the yield rate of the semiconductor products is improved, costs can be decreased and the highly reliable semiconductor is obtained.

Then the result is discriminated while codes of the DA converter are all 0. A value representing the absolute value of the input quantity larger by LSB/2 as 1 and smaller by it as 0 is stored in a correction memory. Only with the content of the correction memory set to 1, the digital code of the successive comparison register is incremented by 1.
