The invention relates to a functionalized laminated optical element comprising: &#x2014;An optical base element; &#x2014;A functional film structure consisting of a single layer or a multilayer structure; &#x2014;A layer of a pressure-sensitive adhesive of optical quality, placed between one surface of the optical base element and the functional film structure so as to permanently retain said functional film structure on the surface of the optical base element. Said functionalized laminated optical element maintains its integrity after typical processing of an optical article which includes wheel edging. More particularly the invention relates to the use of a specific adhesive system for improving the wheel edging resistance of functionalized laminated optical element. The functional laminated optical may be an ophthalmic lens.

Provided is a PSA sheet having a PSA layer. The PSA sheet has a first face and a second face. The first face is a first adhesive face formed of one surface of the PSA layer. The first adhesive face has a 10-point mean roughness of 1000 nm or less. The PSA layer has a storage modulus of 0.08 MPa or greater at 100&#xb0; C.

The present invention relates to a permanent magnet obtained by wet-mixing a Dy compound or a Tb compound with a magnet raw material to coat a surface of the magnet raw material with the Dy compound or the Tb compound, and sintering a green sheet obtained by mixing the resulting magnet raw material with a resin binder and molding the resulting mixture. Since the present invention has the above-mentioned constitution, it becomes possible to sufficiently improve coercive force by Dy or Tb while decreasing the amount of Dy or Tb used. Further, it can be prevented that Dy or Tb is solid-solutionized in magnet particles to decrease residual magnetization.

The present invention relates to a permanent magnet manufactured by steps of: wet-pulverizing a high-melting metal element-containing organic compound or a precursor of a high-melting ceramic in a solvent together with a magnet raw material to pulverize the magnet raw material into fine particles having a grain size of 3 &#x3bc;m or less and to coat a surface of the pulverized magnet raw material with the high-melting metal element-containing organic compound or the precursor of the high-melting ceramic; adding a resin binder to the magnet raw material coated with the high-melting metal element-containing organic compound or the precursor of the high-melting ceramic; producing a slurry by kneading the magnet raw material and the resin binder; molding the slurry into a sheet form to prepare a green sheet; and sintering the green sheet.

A resin lip type seal () capable of increasing safety against rupture by reducing rigidity of a plate-like lip () bent around a tip point A of a approximately wedge-shaped recessed part () to reduce stress concentration at the point A, suppressing the lowering of sealability due to a reduction in creep of the lip, and increasing the follow-up capability of the lip to the eccentricity of its axis. Indentations are formed on the slidable contact surface () of the plate-like lip () or/and the anti-slidable contact surface () thereof. Indentations () are also formed on the sloped slidable contact surface () of the inner lip () of the seal. Then, the ratio of the portion of each of the slidable contact surfaces where the indentations () are formed is &#xbd; or more of each of the surface areas of the slidable contact surfaces ().

Lip type seal

There is provided a plunger seal () for a fuel injection pump for a direct-injection gasoline engine, in which, even if a resin material is used for a fuel seal member (), the plunger seal can be made compact, sealing ability is increased, and assembling man-hours can be reduced, and in which set sealing performance can be achieved when a U-shaped elastic member () for applying an energizing force in a diametrical direction is used in a groove () formed in the fuel seal member (). The resin fuel seal member () and an oil seal member () are assembled to form one seal system. Further, when the U-shaped elastic member () is installed in the groove (), an axial position (L) of an end surface () at the side opposite to the sealed object of a fixing collar () formed on an inner peripheral surface of the groove () is positioned at the side (B) opposite to the sealed object than the axial position (L) of a leading end portion () of a seal lip () of the fuel seal member ().

Plunger seal for pump

Leakage of a combustion gas is prevented by installing a seal ring in an annular groove provided in the outer peripheral surface of a fuel injection valve. Further, a combustion gas leaked from the seal ring is sealed in by providing a seal washer more on the rear end side of the fuel injection valve than the seal ring. Thus a combustion gas seal for an injection valve is provided, and the combustion gas seal is capable of exhibiting excellent sealing ability for a long term with a simple structure.
