Abstract: A bell-shaped element is placed in a sealed position whereby it rests against the outer wall of the container which is full of solid commodities in order to create a partial vacuum in the inner area of said bell-shaped element and in the gaseous area of the container. A sealing armature subsequently places a sealing cap on top of the opening of the container. When the vacuum is created, a cleanliness element rests against the free edge of the opening of the container in a position which is sealed by means of a liner. The cleanliness element comprises a sieve which retains solid materials inside the container during suction. The cleanliness element subsequently retracts on a plane of its own, wiping the free end of the opening in order to remove debris and solid particles which could prevent the opening from being sealed in a desired manner.

Abstract: An apparatus to charge and seal in contents is provided with a supporting portion for containers, holding portions for seal plugs, airtight chambers, a pressure gas supplier and a vacuum pump. The container has a receiving chamber and it is to be put on the supporting portion being the chamber is charged with contents and being the chamber's opening portion faced upward. The seal plug is for sealing the opening portion. The airtight chamber is composed of a main portion and a cap portion. The main and cap portions freely move relatively and freely contact tightly, then they surround the supporting and the holding portions in airtight condition. Further, the supporting portion and the main portion freely move relatively in airtight condition, so as the holding portion and the cap portion do, and the supporting portion and the holding portion are freely separated from each other.

Abstract: In a detector included in a VPP generating circuit in a DRAM, an external power supply potential is applied to the gate of an N-channel MOS transistor for regulating a through current of an inverter for outputting an inversion signal of an output signal of a comparator. Since a drain-source voltage of the N-channel MOS transistor can be set to be lower than a threshold voltage Vthn of the N-channel MOS transistor, an operation margin of the detector under conditions of a low voltage and a low temperature is made wider as compared with a conventional technique.

Abstract: A method of verifying an encapsulation of quick-setting adhesive in a small hermetically sealed reservoir cup from which the adhesive is dispensed on depression of a reservoir piston sealing the mouth of the reservoir cup. The method includes feeding a group of small reservoir cups to a filling station, determining an alignment of the group of small reservoir cups within the filling station, and flooding the interior of each cup at the station with cure preventing gas, if the group of small reservoir cups is determined to be aligned. The method further includes depositing a predetermined amount of quick-setting adhesive into each of the reservoir cups, immediately after flooding, and inserting a piston into each of the reservoir cups on top of the adhesive while flooding. The method involves the use of an apparatus for encapsulating the adhesive in the reservoir cups with the piston. The method ensures that the apparatus will properly encapsulate the quick-setting adhesive in each reservoir cup as designed.

Abstract: A method and apparatus for packaging food products provides evacuation of air and application of purging gas in two stages. The first stage evacuates air and applies an initial gas flush to a first group of packages while the second stage provides an evacuation of a portion of the gas initially applied and applies a second gas flush to the group and then seals the packages. The packages include food containing bases which enter the first stage station of the apparatus where lidding material is laid over a small leading portion of the group, and as this group is transported to the second stage station the lidding material is fed onto the remainder of the bases of the group. Each station includes an evacuation chamber having a base receiving cavity, the second station including base receiving dies acting in conjunction with a heater for bonding the lidding material to the bases. The cavity is closed after two groups of bases have been indexed into the cavity.
