Title: Heat exchanger
Inventor: FUJII TADASHI
IPC: F28F9/02
Filed: 1986-03-28
Abstract: PURPOSE:To provide a heat exchanger removing the heat of an atomic pile without destroying the soundness of heat-transfer tubes even at the time of natural circulation by inserting an inner the having a smaller thermal expansion coefficient than that of the heat-transfer tube into the tube inside to be in close contact with the tube from an upper tube sheet to which the heat-transfer tubes are fixed. CONSTITUTION:A heat-transfer tube 1 is fixed by an upper tube plate 3 and a lower tube plate 4 and in the inside of the tube 1 an inner tube 2 having a smaller thermal expansion coefficient than that of the tube 1 is inserted without a gap between the tube 1 and itself. When a pump in a cooling system is stopped, the upper part of the exchanger becomes high in temp. due to natural circulation. A gap is formed between the tubes 1 and 2 by the difference in their thermal expansion coefficients and the gas in the tube 1 remains in the gap. Through the tube 2 is exposed to a high temp., heat is not transferred to the tube 1 side because its thermal conductivity coefficient is very small. Thus, functions are so divided that a temp. boundary is kept at the tube 2 and the pressure boundary of the cooling system is kept at the outside the therefore, the soundness of the heat-transfer tubes is improved.

Title: Low noise amplifier
Inventor: KIYONO KIYOHARU
IPC: H03F3/60
Filed: 1991-04-01
Abstract: PURPOSE:To provide a low-noise, small-sized receiver by arranging a series circuit comprising a resonance circuit and a resistor between an output terminal of a semiconductor amplifier element and the ground terminal. CONSTITUTION:A parallel circuit comprising a capacitor 13 and an inductor 14 is connected in series with a capacitor 12, and a resonance circuit 15 is in parallel resonance with respect to a reception signal frequency and in series resonance with respect to an image signal. Thus, a reception signal amplified by a pre-stage FET1 reaches a post stage FET1 through an inter-stage matching circuit 3 without being attenuated. On the other hand, an image signal made incident from an antenna 5 or generated at the pre-stage FET1 is almost absorbed by a resistor 11. Not only the image signal made incident externally but also the image signal generated from the FET1 is absorbedby providing a series circuit comprising the resistor 11 and the resonance circuit 15 between the output terminal of the FET1 and the ground. Thus, low noise performance of the receiver is attained.
