IPC: F16L27/08
Filed: 1992-04-10
Abstract: PURPOSE:To realize high speed rotation by equipping a micro opening between a joint main body and the fluid passage opening end of a rotary shaft, equipping a pressure descent chamber adjoining the micro opening, a drain hole communicating with the chamber and an opening between a bearing portion and the rotary shaft, and supporting the rotary shaft by means of compressed air. CONSTITUTION:When starting is conducted, compressed air jets through throttle holes 25 via an air supply joint 22, and is fed to a bearing opening 5, and a joint main body 1 is supported at a rotary shaft 4 without contact. A high pressure processing liquid or the like passes a high pressure fluid supply joint 11, the fluid passage 6b of the joint main body 1 and is delivered to a main shaft 8 via the fluid passage 6a of the rotary shaft 4 from an opening end 12. Part of it jets into a pressure descent chamber 19 via a micro opening 16 and the fluid passage opening end 7 of the rotary shaft 4 side. As its sectional area is large in comparison with the micro opening 16, pressure descent is made, and pressure is reduced more than pressure at fluid passages 6a, 6b. The pressure descent chamber 19 adjoins the bearing opening 5, but its pressure is low, so the fluid does not invade the bearing opening 5. The fluid of the pressure descent chamber 19 is discharged through a drain hole 20.

Filed: 1983-05-24
Abstract: PURPOSE:To obtain a beam having good response of acceleration voltage control and quite low ripple in the beam current through simple structure by applying correction voltage of same phase and amplitude with the ripple component of the acceleration voltage onto the anode. CONSTITUTION:The primary of a correction booster transformer 14 for producing the correction signal from the ripple current flowing through a capacitor 5 is connected to the output terminal of acceleration voltage in series with a smoothing capacitor 5 while the secondary is connected to the ground and anode to be in phase with the primary. The auxiliary electrode 15 is grounded at 8<4>'. Consequently the substantial acceleration voltage will be the voltage between the filament 31 and the auxiliary 15. An electrostatic lens is constructed between the anode 33 and the auxiliary electrode 15, but since the voltage to be applied onto the auxiliary electrode is several % of the acceleration voltage its influence is negligible. Since the capacity of a smoothing capacitor 5 can be selected only from the color astigmatism of the beam, it is low and never influence onto the response of a servo amplifier 12.

Abstract: PURPOSE:To eliminate an oppressive sensation on one's chest which will be caused by an automobile seat belt that will be stretched in response to the ignition switch operation and the load of one's seating, by clamping the belt after stretching it when one is seated with one's back against the back of the seat. CONSTITUTION:When one is seated, a switch 23 is turned ON, and then when an ignition switch 22 is turned ON, a motor 16 is driven. As a result a flexible wire 18 is pulled to rotate an anchoring member 24 counterclockwise to cause a friction engaging section 30 to move away from a lower section 27 of a guide member 12. Therefore the friction engagement of the seat belt 9 is released, and the belt 9 is pulled by a retractor (not shown) to fasten him. When he is leaned against the seat back 2, the switch 15 is turned on, and the motor 16 is stopped to release the tension of the wire 18. Thus the anchoring section 24 is rotated in a direction opposite to R by a spring 40 so that the belt 9 is anchored between the engaging section 30 and the lower section 27 to be stretched. Thus, an oppressive feeling on his chest can be eliminated.
