Title: Tension adjusting device for extremely thin band plate take-up machine
Inventor: FUKUYAMA GORO
IPC: B21C47/00
Filed: 1988-07-12
Abstract: PURPOSE:To prevent a metallic extremely thin plate from being cut and damaged by using jointly a pressure type floater with a tension adjusting device and a differential roller, controlling gas blowout pressure or a flow rate from the floater and adjusting temporarily its tension. CONSTITUTION:Air of prescribed atmospheric pressure and flow rate is fed to air floaters 10, 13 and 14 by an air feeding device 32, and while blowing it out of an exhaust nozzle 1a, it is fed from a quenching extremely thin band plate casting machine. Subsequently, a quenching extremely thin band plate W is wound round and run by non-contact, tension is measured by a tension detector 30 and a hydraulic device 33 is operated through a control panel 31, the air floater 10 is allowed to ascend and descend by a hydraulic cylinder 12, and by adjusting temporarily its running speed and while adjusting to prescribed tension, the band plate is taken-up like a coil by a take-up machine B. In such a way, a shock which is generated by tension shortage and a sudden increase of tension at the time of winding can be absorbed by a cushion effect caused by gas blowout pressure, and it can be prevented that the metallic extremely thin band plate is cut and damaged.

Title: Fuel injection valve
Inventor: SATO TAKESHI
IPC: F02M45/00
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To restrain initial injection rate by forming a fluid-tight chamber which decreases the closed volume of fluid and a retreat chamber which stores fluid retreating from the fluid-tight chamber and narrowing the passage crosssectional area of communication passage between the fluid-tight chamber and the retreat chamber when a protruding part formed at the outer periphery of a valve element retreats. SOLUTION: When a back pressure control valve 35 is opened by a fuel injection valve driving control part, the fuel in a control chamber 32 is discharged from a fuel discharge passage 34, the amount of fluid flowing out of the control chamber 32 becomes more than the charging flow rate of the fluid flowing into the control chamber 32, so that fuel pressure in the control chamber 32 drops. Therefore, the pressure force which energizes a needle valve 23 in the valve opening direction becomes higher, and the needle valve 23 starts retreat. When a rod collar part 23e retreats along with the needle valve 23, the closed volume of oil in the fluid-tight chamber 37a decreases, the pressure in the fluid-tight chamber 37a rises, so that resistance is generated by the pressure and the retreat speed of the rod collar part 23e lowers.  It is thus possible to restrain the initial injection rate from decreasing, thereby decreasing combustion noise.

IPC: B31B50/32
Filed: 1986-07-24
Abstract: A method for producing a packaging container having a pressure relief valve that is tightly secured to the inside of the packaging container and closes off an opening in the wall of the packaging container. To seal off the pressure relief valve, a fluid sealant is introduced into the valve, after the valve has been secured to the packaging container. To this end, an opening is punched by a hollow needle into the wall of the packaging container in the area coinciding with the pressure relief valve, and through the hollow needle a droplet of sealant is deposited in the peripheral zone of a membrane of the pressure relief valve. By capillary action, the sealant enters into the gap between a carrier part and the membrane of the valve and becomes distributed over this area.
