Title: Housing device with releasing means
Inventor: YAMAMOTO MASANORI
IPC: F24F5/00
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a housing device for protecting an inside specimen at power failure time by detecting operational abnormality of a control mechanism by a detecting means, rotating a damper member in the opening direction, and releasing a sealed state by opening a small hole arranged in a main body. SOLUTION: A releasing means 4 is composed of a small hole arranged on a side surface of a main body 2, a damper member 7 for blocking up the small hole 2 and a driving means 6. A rotary shaft driving means is arranged in the driving means 6, and a tension spring and a second energizing means are installed in a rotary member arranged in a connecting mechanism. An energizing force adjusting means for interlocking with magnetic force of a solenoid 15 is arranged in the second energizing means. At normally operating time, the damper member 7 is put in a state of closing a small hole 5. When abnormality such as power failure is caused, an electric current does not flow to the solenoid 15, energizing force by the energizing force adjusting means weakens, the rotary member rotates by energizing force of the tension spring, and the damper member 7 stops in an opening state.  Thus, an inside environment can be set equal to the outside at abnormal time, so that a specimen can be protected.

Filed: 1993-03-17
Abstract: PURPOSE:To improve the accuracy in detection of an alignment position by automatically changing a reference signal in order, according to the preset rule, and setting the reference signal so that the correlatively operated value may be maximum. CONSTITUTION:The signal D[x] issued from a mark for positioning is detected. At this time, in case that the intensity of a signal is not within a certain determined range, the intensity is adjusted. Next, the position where the maximum value of a correlation value AO(x) can be obtained is detected by performing the correlation operation between it and a reference signal SO(x). Furthermore, it is so arranged that the position can be detected between it and a further suitable reference signal S1(x) by enabling the reference signal SO(x) to be automatically changed, according to the signal. An alignment position can be detected with high accuracy by seeking such a reference signal that the maximum value of the correlation value can be gotten, this way.
