Title: Structure for fixing pressure vessel housing
Inventor: MATSUMOTO KOICHI
IPC: G21C13/00
Filed: 1995-01-09
Abstract: PURPOSE: To mitigate thermal stress generating in end plates and welding part of a vessel in starting operation by making a gap formed between the inner surface of end plate penetration hole of a housing and the outer surface of the housing larger than the gap formed between the inner surface of stub tube or builtup welding parts and the outer surface of the housing. CONSTITUTION: The gaps between a housing 3 and a stub tube 4, and between the housing and an end plate 2 are changed by the tube 4 part and the end plate 2 part. More in detail, the gap 7 formed between the housing 3 and the end plate 2 is made ten times or more the gap between the housing 3 and the tube 4. By providing the gap 7, the air layer formed in the gap 7 works as insulator, suppresses the thermal flow from the end plate 2 to the internal fluid 8 in the housing 3 and makes temperature rise of the end plate 2 at startup easy, and the temperature difference between the tube 4 and the end plate 2 decreases, which leads to mitigating the thermal stress generated in the welding part 5.

Title: Amplifying circuit
Inventor: ADACHI TOSHIO
IPC: H03F3/34
Filed: 1990-01-10
Abstract: PURPOSE:To stabilize the circuit without increasing the current consumption in the absence of a load by connecting a current source to the output terminal of an output amplification means. CONSTITUTION:The current source is connected to the output terminal of the output amplification means controlled with the output of a differential amplifica tion stage. Namely, the output terminal changes toward a power source VDD when the current source is provided between the output terminal and the power source VDD and toward a power source VSS when the current source is provided between the output terminal and the power source VSS. At this time, when the current flowing to the output amplification stage 6 becomes too small, the output changes toward the power source VSS by a constant current source 7. The output of the output amplification stage 6 is fed back to the inverted input terminal of an operational amplifier 1, so the output voltages of differen tial amplification stages 2 and 3 vary toward the power source VSS and feed back is provided so that a current flows to a PMOSFET 4; and the output of the output amplification stage 6 becomes stable, and consequently the opera tional amplifier becomes stable. Consequently, the current power consumption is suppressed and the stability is improved.
