Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To improve thermal efficiency of a reaction chamber, improve the throughput of treated substrates, improve productivity of the substrates, make reaction chamber and at a low cost, and facilitate the maintenance. SOLUTION: A substrate treatment apparatus has a reaction tube 31, whose inside is depressurized, into which reactive gas is supplied and in which a treated substrate 11 is placed and heated by an external heating means. A reinforcement part, which withstands a stress produced by a pressure difference between the inside and outside of the reaction tube 31, is formed at least on the region of the reaction tube 31 other than region facing the treated substrate 11. With this constitution, since the thickness of a heating transmitting window facing the treated substrate 11 is thin, the heat from the heating means outside the reaction tube can be can be transmitted easily through the heating transmitting window and the heat from the heating means is transmitted to the treated substrate efficiently, so that the temperature of the substrate to be treated rises quickly.  Furthermore, as the heat capacity of the reaction tube is small, the temperature falls quickly too.

Title: Detecting apparatus of abnormal overheating
Inventor: SENBA KATSUAKI
IPC: H02B13/065
Filed: 1991-10-07
Abstract: PURPOSE:To detect overheating of a conductor of a conducting part within an electric device with high sensitivity in a simple structure irrespective of the electric insulating strength. CONSTITUTION:An upper end of a conductor 3 is cut off to embed a non- magnetic lid 5, a thermosensitive ferrite 6 and a cushion material 7 in the conductor. At the same time, a permanent magnet 8 is interposed between the cushion material 7 and the bottom surface of the cut part of the conductor 3. If the temperature of the conductor 3 is normal, the permanent, magnet 8 is attracted to the side of the thermosensitive ferrite 6. However, if the conductor is over-heated to the Curie temperature or higher, the attracting force becomes weak and the permanent magnet 8 drops on the bottom surface of the cut part of the conductor 3. In consequence, the permanent magnet 8 vibrates due to an alternating magnetic field H generated by a flowing current. This vibration is transmitted to a wall 1 of a gas tank via a spacer 2 and detected by a vibration detecting sensor 10.

Filed: 1985-11-19
Abstract: PURPOSE:To stablly operate for a long period by driving FET elements after completion of transfer of an input pulse and setting to make all FET elements lower potential than source potential periodically for a fixed time. CONSTITUTION:After transferring signals from V1 to Vn, a switch Q7 for poten tial setting is made to on state by a clock of CK 3, and potential V is supplied to the gate of Q4. Completion is detected by a 1 line completion signal detecting section, and the switch Q7 for potential setting is made on by the signal. Signals at points A, B and C change as shown in the figure and the point C is set to specified potential V for a fixed time. When V is lower potential than V0, gate potential of Q4 becomes low potential to the source potential for a fixed time. Thus, application of electric field of only the same direction to an insula tor layer can be prevented, and characteristic of the FET can be made stable for a long term.
