Title: Easily openable sealed container
Inventor: YOTSUYANAGI JUNJI
IPC: B65D77/20
Filed: 1990-01-09
Abstract: PURPOSE:To prevent a gas-barrier layer from being peeled off and provide the feature of a stable unpacking by a method wherein a relief groove is located all around the upper surface of an outer layer part of a container at a predetermined distance from its inner peripheral edge to the outside, and the outer peripheral edge of a gas-barrier layer is extended into the relief groove. CONSTITUTION:Since the outer peripheral edge of a gas-barrier layer 23 is located in a relief groove 25 provided in the outer layer part 22 of a container 20, the outer peripheral edge thereof is kept out of contact with a lid 21. When the lid 21 is being peeled off, therefore, the exertion of a pulling force by the lid 21 on the outer peripheral edge of the gas-barrier layer 23 can be avoided. As a result, the resistance of the gas-barrier layer 23 to the pulling force of the lid 21 at both the inner and outer sides thereof attached to the lid 21 is created, thereby preventing the outer peripheral part of the gas-barrier layer 23 from being peeled off together with the lid upon unpacking. The gas-barrier layer 23 and the lid 21 can be attached together at a constant width between the relief groove 25 of the outer layer part 22 and the inner peripheral edge 22b thereof all around the periphery. Therefore, an adhesive strength between the container 20 and the lid 21 becomes uniform all around the periphery thereof and the lid can be peeled off from any point by an equal force.

Title: Device for inspecting inside diameter of extremely small hollow hole and gauge holder used therefor
Inventor: TSURUOKA YOSHIO
IPC: G01B5/12
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To make an inside-diameter gauge insertable into an extremely small hollow hole to be measured with a constant pressure and the inserted length of the gauge accurately measurable when the gauge stops on the way. SOLUTION: When a stage 4 is moved forward, an inside diameter gauge 3 is inserted into the extremely small hollow hole 2 of an object to be measured. Since the gauge 3 is attached to a gauge holder in a state where the gauge 3 can slide forward and backward and is pushed with a preset inserting pressure, the gauge 3 is always inserted into the hole 2 with a constant pressure. Therefore, no unreasonable force is applied to the gauge 3 and the gauge 3 is not broken. In addition, when a force stronger than the inserting pressure acts on the gauge 3 due to the friction between the gauge 3 and hole 2, the gauge 3 slides backward and the positional change of the gauge is detected by means of a sensor 13.  Since the stage 4 is stopped when the sensor 13 detects the positional change of the gauge 3, the inserted length of the gauge 3 can be measured objectively based on the moving distance of the stage 4.

Title: Methane gas generator
Inventor: TOMIOKA TOSHIICHI
IPC: F17B1/26
Filed: 1982-01-11
Abstract: PURPOSE:To enable to realize light-weight small size water sealing type gas tank by a structure wherein a sac-like material, as a side wall of which bellows- shape creases are employed, are used as the gas tank. CONSTITUTION:When the rate of gas consumption of gas consuming apparatuses is larger than the rate of fermentation of fermentation gas in a methane fermentation tank, the gas 2 stored in the bag-like material 1 flows out of the tank through a gas distributing pipe 3 to be charged to the gas consuming apparatuses. When the magnitudes of both the rates mentioned above are reversed, the fermentation gas flows in the gas tank and is stored therewithin. Because the gas tank is constituted of the sac-like material, the capacity of which nearly equals to the maximum volume to be stored, and yet the weight of the gas tank is the weight of structural members only, the light-weight small size gas tank is resulted.
