Abstract: Disclosed is an ophthalmic composition which is characterized by containing (A) a vitamin A, (B) a polyoxyethylene polyoxypropylene glycol, and (C) an oil component that is selected from the group consisting of castor oil, soybean oil, sesame oil, peanut oil, olive oil, almond oil, wheat germ oil, corn oil, rapeseed oil, sunflower oil, purified lanolin and gel hydrocarbon.

Abstract: Disclosed is an ophthalmic composition containing (A) not less than 50,000 units/100 mL of vitamin A, (B) not less than 0.4 W/V % of a polyoxyethylene polyoxypropylene glycol, and (C) trometamol.

Abstract: Disclosed is a composition for soft contact lenses which enables to suppress adsorption of a basic chemical substance onto a soft contact lens. This composition for soft contact lenses comprises (A) a basic chemical substance selected from amines having a secondary amino group and/or a tertiary amino group and salts thereof, and (B) one or more substances selected from amino acids and salts thereof, acid mucopolysaccharides and salts thereof and cyclodextrin, while having a pH of 3.5 to 4.8. Also disclosed is a method for suppressing adsorption of the basic chemical substance onto a soft contact lens.

Abstract: A vibration damper comprises a first plate 11 that is fixed to one framework member 51, a second plate 13 that is fixed to another framework member 53, and an elastic material 15 that is filled in the interstices between the first plate 11 and the second plate 13. A first clearance W1 is formed between the another framework member 53 and a first fixing portion 21, and a second clearance W2 is formed between the first framework member 51 and a second fixing portion 29. The first plate 11 is made of a steel plate that is formed directing from the first fixing portion 21 to the second fixing portion 29, and the second plate 13 is made of a steel plate that is formed directing from the second fixing portion 29 to the first fixing portion 21. A space portion 50 constituted by the first clearance W1, the second clearance W2, the first plate 11, and the second plate 13 has a dimension which is at least sufficient for insertion of a joist 57 therein.

Abstract: In one embodiment, a magnetic head includes a read element, a write element, a write upper shield positioned in a downtrack direction from the write element, a first resistance detecting element positioned on an air bearing surface (ABS) side in a first cross-track direction from the read element, a second resistance detecting element positioned on the ABS side in a second cross-track direction from the write element, a third resistance detecting element positioned on the ABS side in a third cross-track direction from the write upper shield, a protective film positioned near the read and write elements, first, second, and third resistance detecting elements, and the write upper shield, and terminals positioned on an end surface side of the magnetic head, the terminals being coupled to the write element, the read element, the first resistance detecting element, the second resistance detecting element, and the third resistance detecting element.

Abstract: A multistage compressor has a yoke with a cross slider and roller bearings pressed against the sides of the cross slider by spring forces to enable the cross slider to slide smoothly within the yoke. The spring forces are generated by springs disposed between the yoke and a liner plate that urges the roller bearings against the cross slider. By this construction, the yoke and cross slider are not damaged during operation of the compressor even if the dimensions of the members change due to thermal expansion.
