Filed: 1986-11-04
Abstract: PURPOSE:To suppress the reduction of a gain and to improve a side rope characteristic by making the aperture distribution of a main reflection mirror into a non-rotation symmetry by mirror-correcting the main reflection mirror and a sub-reflection mirror. CONSTITUTION:When an orthogonal coordinate system x-y with a center 0 of an aperture as an original point is determined, an electric field radiated from a primary radiator 1 is reflected by a mirror surface system, and thereafter, the main reflection mirror 5 and a sub-reflection mirror 4 are mirror- corrected so that the amplitude distribution when the field arrives at the aperture surface 6 of the main reflection mirror 5 can be different in the surface of x=0 and in the surface y=0. Consequently, when the surface of x=0 and a uniform distribution and the surface of y=0 is a taper distribution, the uniform distribution contributes to the improvement of the gain and the low side rope in the surface of y=0. The side rope characteristic in the surface of x=0 is deteriorated more than the case of the rotation symmetrical distribution.

Title: Exclusive or circuit
Inventor: KANETANI KAZUO
IPC: H03K19/21
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To make the XOR circuit fast by providing an OR circuit constituted by connecting bases of respective transistors to a 1st node point and a 2nd node point, respectively, connecting their emitters to a 3rd node in common, and connecting a current source to the 3rd node point. SOLUTION: Currents are so defined that Iab=Icd, Iab>=Iy, and OUT('1')> VBB1>OUT('0'). When '0' (even) is obtained as an XOR output, the currents Iab and Icd are made to flow to one of resistances R10 and R20 mutually. Since VBB1>OUT('0'), a current (Iab+Icd+Iy) flows to a resistance R3. Then '0' is obtained as the XOR output through an OR circuit W1. When '1' an odd number is obtained as the XOR output, both the currents Iab and Icd flow concentrically to one of the resistances R10 and R20 and do not flow to the other. Then '1' is obtained as the XOR output through the OR circuit W1.

Filed: 1987-10-19
Abstract: PURPOSE:To prevent the occurrence of weld defects by forming an overlap so that the thinner surface of the Cr oxide film is faced to the inner side and inserting the overlap between bare wire electrodes to perform welding. CONSTITUTION:A differential coating free steel thin plate with different thickness of Cr oxide layer, 10a and 10b of both surfaces is used to form a perform 11 with the thinner Cr oxide layer 10a placed to the interior side. The inner and outer wire electrodes 15 and 16 are made of one continuous bare copper wire and the preform 11 is welded in order thereby. At this time, the lower side edge 11a of the overlap 12 is located in the vicinity of the gradient surface 18a and inserted between electrode rolls 13 and 14. Since the thinner oxide layer 10a is interposed in the inner side, electric resistance is reduced and a heating value at the inner side decreases. Further, since the flow of material is generated in the vicinity of a weld zone and the heating value of the overlap 12 is uniformized inside and outside, the occurrence of defects at the time of welding is surely prevented.
