IPC: F16H48/12
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a ball transmission type differential limiting device capable of obtaining a reliable differential limiting effect through a simple structure. SOLUTION: The rotational force of a differential case 1 is transmitted in the groove of a disc plate 3 through each ball 5 for integral rotation. When a rotational difference is produced at each disc plate 3, each ball contained in the oblong hole 4c of a center plate 4 is guided in the groove 3b of each disc plate for reciprocating movement. When a force to produce a rotational difference is exerted from one disc plate side, in the other disc plate, a ball is on the driven side at the differential time causes a groove being the main shaft side at the differential to follow own movement, whereby a reaction force generated at a current time forms resistance and differential motion of the disc plate 3 is limited. Spheroidal graphite cast iron or the like is applicable to the differential case 1 and the spheroidal graphite cast iron, an alloy steel or a precise casting and further a sintered material are applicable to a center plate and a thrust washer.

Abstract: PROBLEM TO BE SOLVED: To obtain a new mutant pullulanase, having excellent resistance to an oxidizing agent by deleting one or more methionine residues in amino acid residues constituting the pullulanase or substituting the one or more methionine residues with an optional amino acid residue other than Cys and Met. SOLUTION: This new mutant pullulanase is obtained by deleting at least one methionine residue in amino acid residues constituting the pullulanase or substituting the methionine residue with an optional amino acid residue other than Cys and Met, has excellent resistance to an oxidizing agent and is varied in the optimal pH and useful for wide applications such as formulation in a detergent composition containing a bleaching agent formulated therein, a composition, etc., for saccharifying starch. As a result of various investitations of a base sequence of a pullulanase gene derived from a Bacillus sp. KSM-1378 strain on a change in properties due to a site-specific variation, it is found that the methionine residue contributes to the inactivation with the oxidizing agent.  The mutant pullulanase is obtained by providing a structure in which the methionine residue is deleted or substituted with the other amino acids residue and expressing the gene.

Title: Oxygen partial pressure measuring sensor having two measuring areas
Inventor: THUMFART DIETER
IPC: G01N27/407
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To protect an electrode from a chemical influence caused by an atmospheric component by enclosing the electrode by a gas diffusion bulkhead, mutually differing the gas permeabilities of a plurality of gas diffusion bulkheads, and connecting the electrode to a voltage source through a current detecting device. SOLUTION: An electrode 4 is airtightly connected to a solid electrolyte 20, and enclosed by a gas diffusion bulkhead 2. An electrode 5 is similarly airtightly connected to the electrolyte 20 and enclosed by a gas diffusion bulkhead 3. The two bulkheads 2, 3 must limit the direct penetration of the ambient atmosphere to the electrodes 4, 5. Therefore, the two bulkheads have small glass permeability. When a working voltage is applied, O2 ion is moved from the electrode 4 to the electrode 5. The bulkhead 2 having holes 7 acts on the ambient atmosphere carried later. The flowing direction of O2 ion is reversed when the polarity of the working voltage is reversed, and the bulkhead 3 acts on the ambient atmosphere to determine a measuring area. The area change can be performed by changing only the polarities of the electrodes.
