Title: Exhaust system with turbo molecular pump
Inventor: SAITOU NAOTAKE
IPC: F04B25/00
Filed: 1980-04-25
Abstract: PURPOSE: To reduce vibrations transmitted to a vacuum device by providing a bypassing exhaust channel bypassing the main valve of the turbo molecular pump employed for an electron microscope and the like and by making an exhaust pipe vibration-proof.  
     CONSTITUTION: A valve 15 is provided in the middle of the bypassing exhaust pipes 14 and 16 communicating the main exhaust pipe 2 directly with a vibration- proof main exhaust pipe 12, while TMP5 is connected with a valve 7 by the vibration-proof exhaust pipe 13. When the difference in pressure between the upstream and downstream sides of the main valve 3 is large, the main valve 3 is opened after the difference is reduced by opening the valve 15. Since the exhaust side of TMP5 is connected with the valve 7 fitted to a frame 9 through the intermediary of the vibration-proof exhaust pipe 13, the vibrations of RP20 and the frame 9 are absorbed completely and not transmitted to TMP5, and, together with the operation of the vibration-proof main exhaust pipe 12, the vibration-proof characteristic of the entire exhaust system is improved.

Title: Electronic equipment
Inventor: MATSUNO TERUO
IPC: H05K5/06
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To make an electronic equipment structurally independent of the effect, which accompanies penetration of dusts or water on a respiratory action, by a method wherein a cover of a double structure, which consists of a cover and an inner cover, is formed. SOLUTION: Bearings and an electronic component generate heat by the starting of the detection operation of a rotary encoder 1 to expand the volume in the interior of the cover 5. When the air in the interior of the cover 5 is expanded, the air in an inner cover 10, which consists of an elastic material, is also expanded and the air in an air chamber 15 is exhausted in the outside space through gaps between the fixed parts of the cover 5. Moreover, when the work of a conveyor system is stopped, the air in the cover 5 is cooled in reverse and the volume in the interior of the cover 5 is decreased. The cover 10 follows this decrease to shrink and the air in the outside is sucked in the air chamber 15 via the gaps this time. That is, a respiratory action due to the synchronous evacuation and intake of the cover 10 works on the basis of a temperature change.  Thereby, even if dusts, water, oil or the like is sucked in the covers at the time of the intake in the respiratory action, the dusts, the water or the like sucked can be shielded by the cover 10.

Title: Method for measuring dynamic strain gauge
Inventor: SHINNO FUMITATSU
IPC: G01H11/06
Filed: 1990-03-06
Abstract: PURPOSE:To eliminate the need to perform a zero-point adjusting process before measurement and to adjust the zero point automatically during measurement by extracting nearly the same levels which are most among the output levels of an electric signal, and regarding the same output levels as the real zero-point level of a bridge circuit and making corrections. CONSTITUTION:An A/D converter 20 converts the analog output of the bridge circuit 10 into a digital output and sends it out to a zero-point correcting circuit 30. The sampling circuit 11 of the zero-point correcting circuit 30 samples the digital output of the converter 20 at constant intervals of time and writes, for example, 80 digital outputs are written in a memory 12 sequentially in each cycle. An arithmetic circuit 13 detects nearly the same digital outputs which are most among the 80 digital outputs and correct the zero point about measurement data in the memory 12 according to the outputs. Thus, the zero point of the output of the circuit 10 can be corrected automatically, so the zero point need not be corrected before the measurement and no variable resistor for the zero-point adjustment needs to be provided to the bridge circuit.
