Abstract: PURPOSE: To obtain a vacuum packing apparatus that packs food or the like in vacuum by providing the second nozzle communicating with an end suction element through a suction tube, and letting the first nozzle connectable to an auxiliary suction tube that removes air from a rigid food container. CONSTITUTION: When air is removed from a rigid food container 22, a lid 15 of a vacuum packing apparatus 1 is removed, an end of the auxiliary suction tube 21 is attached to the first nozzle 17 of the vacuum packing machine 1 by means of a connecting element 20, the other end of the auxiliary suction tube 21 is attached by means of a valve adapter 30 to a cylindrical hollow 29 of a rigid container 22 that contains food, and a vacuum pump 3 is started. Air in the rigid container 22 is sucked, and a ball 27 is accelerated toward a hemispherical recess 33 during the suction and is in contact with a rib 34. When the suction process is completed, the ball 27 drops and completely seals the hole 28. When taking out the food inside, pressure in the container is equalized with ambient pressure by removing the ball 27 from the hole 28. Thus the lid 24 can be removed easily.

Title: High frequency ion source
Inventor: SAKAI SHIGEKI
IPC: H01J27/16
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To decrease the component ratio of hydrogen ions contained in an ion beam drawn out of a high frequency ion source by setting the intensity of a cusped magnetic field in a sheath formed between a high frequency electrode and plasma in a specified value. SOLUTION: A sheath 36 in which electrons are rarefied according to the difference between the mobility of electrons and that of ions (the former is substantially higher) within plasma 16 is formed between a high frequency electrode 6 and the plasma 16. Since an electric field caused by sheath voltage and a magnetic field caused by a cusp magnetic field are applied to the sheath 16, electrons conduct drift motion within the sheath 36. In this case, the intensity of the cusped magnetic field within the sheath 36 formed between the high frequency electrode 6 and the plasma 16 is set to 1-3 mT (mili tesla). An ion beam 28 is stably drawn out, and component ratio of hydrogen ions contained in the ion beam 28 can be decreased. As a result, the generation of troubles caused by hydrogen ions contained in the ion beam can be avoided.

Abstract: PURPOSE:To make it possible to generate large damping force upon nose-diving or rolling of a vehicle, by connecting a parallel circuit constituting of a check valve and a restrictor valve in series to attitude control valves. CONSTITUTION:Hydraulic dampers 17, 18 on the front side are subjected to compression load upon nose-diving, so that oil in the hydraulic dampers 17, 18 gradually flows out into branch passages 16a, 16b while the oil is subjected to the constricting action of restrictor valves 20, 23. Therefore, large damping force is brought about by these dampers 17, 18 to prevent the front side of a vehicle body from diving. Upon rolling of the vehicle body, it is detected which one of dampers 7, 8, 17, 18 is subjected to large eccentric force, and the thus obtained detected signal is delivered to a control circuit 31 which delivers an electrical current signal to either one of attitude control valves 11, 14, 21, 24 to carry out the operation of change-over, and therefore, oil in the hydaulic damper to which eccentric load is exerted is fed into an accumulator 15 or 25 through the restrictor valve.
