Inventor: KITAMURA TOICHI
IPC: B65D81/24
Filed: 1991-03-11
Abstract: PURPOSE:To enable duration of life and keeping of freshness for a long time by a method wherein an oxygen generating solid agent is placed on a lower edge part, and robsters or crabs are embedded in sawdust and packaged with a wrapping paper which is manufactured by mixing far ultrared rays radiating ceramics, and further housed in a foamed styrene container for transportation. CONSTITUTION:Sawdust 4 is dispersed with an appropriate amount of water, and an oxygen generating solid agent 5 is placed in a lower edge part. Robsters or crabs 3 are embedded in the sawdust 4 and packaged with a wrapping paper 2 which is manufactured by mixing powdery far ultrared rays radiating ceramics and then housed in a container 1 for transportation. As a result, the water dispersed over the sawdust 4 drops down slowly on the oxygen generating solid agent 5 positioned below, whereby oxygen is generated for a long time to keep up oxygen volume in the atmosphere within the package. In addition, the generation of far ultrared rays from the wrapping paper 2, in accompany with restriction of movement by the sawdust 4, is very effective in keeping the robsters or crabs alive for a long time and also in retaining freshness of them.

Title: Diaphragm type electromagnetic pump
Inventor: TSUGE KATSUYUKI
IPC: F04B13/02
Filed: 1986-03-31
Abstract: PURPOSE:To improve release response of two cores and delivery performance, by a method wherein a stroke, in which a moving core is brought into contact with a fixed core, is increased over that in which a control part formed to a part of a diaphragm is brought into contact with a contact part. CONSTITUTION:A stroke L2 in which a moving core 10 is brought into contact with a fixed core 9 during non-energization to a solenoid 7 is increased over a distance, by which the moving core 10 is moved to the fixed core 9, e.g., a stroke L1 in which a control part 11C of a diaphragm 11 is brought into a contact part 12A. This constitution enables a gap of L2-L1 to be formed between the moving core and the fixed core 9 even during final upward movement of the moving core 10 during operation. As a result, since there is no collision between metals, a silent electromagnetic pump can be provided. Further, since, when energization to the solenoid 7 is disconnected, the influence exercised on the moving core 10 by residual magnetism can be reduced to an extremely low value, the return response force of the moving core 10 can be improved, and delivery performance of the pump can be stabilized.

Title: Calorimeter bomb
Inventor: IZUMITANI SUSUMU
IPC: G01N25/26
Filed: 1993-03-31
Abstract: PURPOSE:To prevent the deterioration and damage of an O-ring sealing the outer periphery of a bomb cap by heat or ash by providing the O-ring on the outside of a bayonet engaging section and, at the same time, making the diameter of the cap at the fitting position of the cap larger than the inside diameter of a combustion chamber. CONSTITUTION:Since an O-ring 4 which seals the outer periphery of a bomb cap 2 is provided on the outside of a bayonet engaging section 3, a hot blast generated when a sample catches fire is first blocked by the complicated engaging section 3. In addition, the diameter of the 0-ring 4 fitting position of the cap 2 is larger than the inside diameter of the combustion chamber of this calorimeter bomb, the hot blast reaches the ring 4 through the bent gap of the section 3. Therefore, the temperature of the hot blast drops before reaching the ring 4 and the deterioration of the ring 4 by the heat of the hot blast can be prevented. In addition, such a substance as the ash, etc., generated from the combustion of the sample does not adhere to the ring 4, since the substance is also blocked by the section 3. Therefore, the service life of the ring 4 can be prolonged.

Title: Underground tank for liquefied gas storage
Inventor: MISHIMA KAZUO
IPC: F17C3/00
Filed: 1986-03-31
Abstract: PURPOSE:To make a junction between a thin bottom plate and a circumferential side wall so as not to cause any bending moment there, by supporting a thick bottom plate with a hinge structure. CONSTITUTION:The peripheral edge of a thick bottom plate 4 is mounted on the top of an inner flange part 1a via a shoe 6. With this shoe 6 as a fulcrum, this thick bottom plate 4 is set down to a substantial hinge structure and supported. With this constitution, load merely causes bending moment to the thick bottom plate 4, causing no bending moment to a junction between a thin bottom plate 3 and a peripheral wall 1. Therefore, such a fear that harmful displacement might be entailed to an inner vessel 2 being held by the thin bottom plate 3 is brought to nothing.
