摘要:
An insulating coating composition is described which prevents deterioration of the insulating ability of newly fabricated material and when applied will also restore insulation characteristics to material presently in use. The composition comprises a mixture of1. a main resinous coating of a thermoplastic resin;2. a cation exchange resin which may be either strongly acidic, i.e., one containing sulfur type, sulphonic acid radicals or weakly acidic, i.e., one containing carboxyl groups or phenolic hydroxyl groups; and3. an anion exchange resin which may be either strongly basic, i.e., one containing quaternary ammonium radicals or weakly basic, i.e., one containing amine radicalsA method of arresting or preventing deterioration of insulating coatings is also disclosed by the use of the above materials which when applied will remove disassociated ions which, in turn, prevent formation of an electroconductive film on the surface of the coating.

To provide a dental glass ionomer cement composition having excellent adhesion strength to a metallic prosthesis. A dental glass ionomer cement composition includes a copolymer (A), a fluoroaluminosilicate glass powder (B) and water (C). The copolymer (A) includes a polymer or copolymer of α-β unsaturated carboxylic acid, or includes a copolymer of α-β unsaturated carboxylic acid and one or more kinds selected from a group of acrylamide, acrylonitrile, methacrylic acid ester, acrylates, vinyl chloride, allyl chloride and vinyl acetate. In the copolymer (A), the number of molecules of α-β unsaturated carboxylic acid occupies 50% or more of the total number of molecules. The dental glass ionomer cement composition further includes a compound (D) which contains a sulfur atom in one molecule, includes a carboxylic group and an amino group and does not include a polymerizable group.

An atomizing apparatus (10) includes a housing (12), and a tank (40) accumulates tap water inside the housing. By electrolyzing the tap water by the electrolysis electrodes (120p, 120m), the water in the tank becomes electrolyzed water. At the first operation after a shortage of water state in the tank is detected, an initial electrolysis operating time is set to 20 minutes (step S210). In a case of not an operation after the shortage of water state but a restart of a normal operation, the initial electrolysis operating time is set to 5 minutes (step S224).
摘要:
Embodiments of the present invention allow control over the element height of read and write heads without damage to a lapping surface table when an air-bearing surface is lapped with a row bar or magnetic head slider tilted. According to one embodiment, the air-bearing surface is lapped with the row bar tilted in the longitudinal direction of a slider to compensate element height-wise positional deviations of the read head and the write head. The lapping is performed while changing an inclination angle stepwise and swinging the row bar in the longitudinal direction of the slider centering around an inclination angle at each step. Thus, the element heights of the magnetic pole piece and the read element can be controlled without damage to a lapping surface table.

A seatbelt retractor includes a spool for winding a seatbelt; a locking mechanism having a locking member rotatable together with the spool in a normal condition and being prevented from rotating in a seatbelt-withdrawing direction in an emergency condition; an energy-absorbing mechanism interposed between the spool and the locking member for absorbing shock energy exerted on a passenger when the spool rotates in the seatbelt-withdrawing direction relative to the locking member in the emergency condition; and a motor for generating power to rotate the spool. A power transmission mechanism is connected to the locking member for transmitting the power of the motor to the spool through the power transmission mechanism, the locking member, and the energy-absorbing mechanism.
