Title: Refrigerator
Inventor: YOKOYAMA NAOKI
IPC: F25D11/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of refrigerant being encapsulated by providing a combustible refrigerant encapsulated in a refrigerating cycle, a refrigerating machine oil compatible with the refrigerant, a storage chamber being cooled through refrigerating cycle, and a body including the storage chamber provided with at least one door thereby preventing the refrigerant from standing in a gas/liquid separator. SOLUTION: A storage chamber 23 comprises a body 21 and a door 22. When a compressor 26 is operated, high temperature high pressure combustible refrigerant 29 delivered from the compressor 26 flows into a condenser 27 where it is condensed and liquefied through heat exchange with the outdoor air and flows into an expansion mechanism 28. The combustible refrigerant is reduced in pressure by the expansion mechanism 28, evaporated in an evaporator 25 and returned back to the compressor 26 after exchanging heat with air in the refrigerator. Since a place causing stagnation of highly viscous refrigerating machine oil 30 is not present in the vicinity of the low temperature evaporator 25, the combustible refrigerant 29 circulates without dissolving into the refrigerating machine oil 30 standing in the cycle and the refrigerating cycle is repeated.

Title: Sealed storage battery
Inventor: ISHIKAWA TAKASHI
IPC: H01M50/457
Filed: 1982-04-20
Abstract: PURPOSE:To increase the life and enhance the characteristic of a sealed storage battery by the combination of a sulfonated separator layer and a non-sulfonated separator layer which contains a surfactant. CONSTITUTION:A non-woven polypropylene fabric is sulfonated by being immersed in commercially available concentrated sulfuric acid of 98% concentration for 20min. Next, the non-woven fabric is superposed on a non-woven polypropylene fabric containing a commercially available surfactant, and these two non-woven fabrics are unified by spot fusion. Thus obtained separator, a positive sintered nickel electrode and a negative pasted cadmium electrode are rolled into a spiral shape, and the spiral member is inserted into a battery case. After that, a given amount of caustic-potash electrolyte is poured in the battery case, and the battery is sealed so as to constitute a sealed battery of the single-2 type. Here, the sulfonated layer of the separator is positioned on the side of the positive electrode, while the layer containing the surfactant is positioned on the side of the negative electrode. As a result, in the negative electrode which touches the non-sulfonated separator layer, a decreased proportion of the electrode surface is wetted by the electrolyte, and an increased amount of gas is absorbed during charging. Consequently, the high-rate charging characteristic immediately after the assembly of the battery is enhanced.

Title: Scroll fluid machine
Inventor: TAKAGI NOBUKAZU
IPC: F04C18/02
Filed: 1991-03-30
Abstract: PURPOSE:To facilitate assembling, to ensure sealing ability and to reduce the manufacturing cost by inserting a shim material for adjusting a gap in a gap between a seal groove and a seal member and forming the sides of the shim material opposite to the bottom portion of a scroll member as a flat surface. CONSTITUTION:A shim material 43 for adjusting a gap between a seal groove 41 and a seal member 42 is inserted in the gap, and the sides of a shim material 43 opposite to the bottom portion of a scroll member are formed as a flat surface. As the shim material 43 is thus inserted, fallout of the seal member 42 at the time of assembling can be prevented, the assembling can be facilitated and the leakage from the side can be reduced by the frictional force among the wall surface of the seal groove 41, the seal member 42 and the shim material 43. Even if the work tolerance of the seal member 42 and the seal groove 41 is made rough, a suitable gap can be ensured, and as the sides of the shim material 43 opposite to the bottom portion of the scroll member is flat, even if the working accuracy of the seal groove 41 is not precise, the sealing ability can be ensured.

Title: Ball stud, its manufacture, device therefor and ball joint
Inventor: HONMA DAISUKE
IPC: F16C11/06
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a ball joint equipped with a ball stud, capable of easily forming a recessed groove part for cover attachment to improve manufacturing. SOLUTION: A roughly spherical ball bead part 29 is provided in the base end side of a roughly cylindrical shaft part 30. A roughly cylindrical base part 31 is formed in the base end side of the shaft part 30. A roughly cylindrical small-diameter part 32 smaller in diameter than the base part 31 is formed in the tip side of the shaft part 30. A protruded part 34 protruded along a peripheral direction is formed by pressing in the small-diameter part 32 away from the end part of the tip side of the base part 31. By the press-forming of the protruded part 34, a recessed groove part 37 recessed in shape is formed along the peripheral direction between the protruded part 34 and the base part 31.  Since the formation of the protruded part 34 in a position away from the end part of the tip side of the base part 31 results in the formation of the recessed groove part 37 between the protruded part 34 and the base part 31, the recessed groove part 37 is easily formed. Since the recessed groove part 37 is formed by pressing, the productivity of a ball stud is improved.
