Title: Rotary type shock absorber
Inventor: KOKUBO NAOYUKI
IPC: B60G17/015
Filed: 1991-07-25
Abstract: PURPOSE:To control a damping force by means of a friction force by a method wherein viscous oil with which a chamber between a partition wall and a rotor is filled generates an internal pressure, responding to a relative rotation speed, in the chamber through resistance of a throttle passage, and the internal pressure is exerted on a piston through an opening, the area of which is differed with a rotor rotation direction to press a friction clutch. CONSTITUTION:The interior of a housing 1 is axially divided into two spaces by means of a partition wall 13. In the one space, a friction clutch 4 and a press piston 9 are provided. In the other space on the back side of the piston 9, a partition wall 11 is located and chambers S1 and S2 are formed at the front and in the rear in a rotation direction by means of a rotor 12 rotatably located in a rotary shaft 3 and the partition wall 11. The two chambers are intercommunicated through a throttle passage 20 formed in a gap between the outer periphery of the rotor 12 and the inner periphery of the partition wall 11. Holes 14a and 14b and holes 15a and 15b opened to the chambers S1 and S2 and to the back of the piston 9, respectively, and differed in an opening area with size are formed in the partition wall 13. The chambers S1 and S2 are filled with viscous oil. Thus, a difference in a damping force is produced by means of the different friction forces of a friction clutch.

Title: Gun cylinder device for spot welding
Inventor: ITOU YOSHIICHI
IPC: B23K11/11
Filed: 1981-12-22
Abstract: PURPOSE:To prevent the generation of dents easily and effectively by providing locking mechanisms to one of upper and lower gun cylinders which are in pairs and are so disposed as to face each other and locking the cylinders when the pressurizing forces of the cylinder attain specified values. CONSTITUTION:The moving stroke S1 of upper gun cylinders 2, 3 is beforehand set larger than the movable stroke S2 of lower gun cylinders 4, 5. When the cylinders 2, 3, 4 are extended simultaneously by changing over operations of solenoid valves, the electrode chips 10b of the cylinders 4 contact with the work W first. Then the electrode chips 10a of the cylinders 2, 3 contact therewith. When the pressures in the pipelines of the cylinders 4 attain specified values, locking mechanisms 24 operate to lock the piston rods 4a respectively separately. Therefore even if the unbalance in load resistance by secondary cables 11, 12 of an electric power source and cooling water hoses is generated, the influence by external factors is offset by the locking and the generation of dents is prevented.

CONSTITUTION:If air is supplied by an air supply fan 8 while a rotor 4 is being rotated by a driving motor 3, supply airstream (a) flows into a hollow space 17 through an air supply port 16 provided in an upper part of an air supply header of the rotor 4 from the inside of an air supply chamber 6 and forms going-down airstream (b) and then horizontal airstream (c). Then the airstream flows through branched pipes 21 and 22, and is diffused out of air supply nozles 23 and 24 into a discharged air treating space as another going-down airstream (d). This going-down airstream (d) which also swirls forces air inside an imaginary column in a lower zone of the rotor 4 to swirl, so that the iniside of a rotation zone comes to have a negative pressure, whereby a rising whirlwind (e) may be generated. The whirlwind (e) rises together with dust making a discharged airstream (f), which enters an air discharging chamber 7 through a suction port 10, and is then discharged by an air discharge fan 9.
