  • Patent number: 11953827
    Abstract: A molecular resist composition is provided comprising (A) a betaine type onium compound having a sulfonium cation moiety and a sulfonate anion moiety in a common molecule, the sulfonium cation moiety having a phenyl group substituted with an optionally heteroatom-containing monovalent hydrocarbon group, the phenyl group being attached to the sulfur atom, and (B) an organic solvent, the resist composition being free of a base resin. When processed by lithography using KrF, ArF excimer laser, EB or EUV, the resist composition is improved in dissolution contrast, EL, MEF, and LWR.

  • Patent number: 11940728
    Abstract: A molecular resist composition and a pattern forming process. A molecular resist composition comprising a sulfonium salt having a cation of specific structure and an organic solvent has a high sensitivity and forms a resist film with improved resolution and LWR, when processed by EB or EUV lithography. The molecular resist composition does not contain a base polymer. The molecular resist composition comprising a sulfonium salt having a cation of specific partial structure has a high sensitivity and forms a resist film with improved resolution and LWR, so that the resist composition is quite useful for precise micropatterning.

  • Patent number: 11796044
    Abstract: A gear device drivingly coupling a drive shaft with first and second axles is provided with a case coupled via gearing with the drive shaft, and rotatable about an axis; a hub that is couplable with the first axle; a clutch member retained by the case and disengageably engaged with the hub; a biasing element retaining the clutch member at a position where the clutch member engages with the hub; and a differential gear set coupling the case via gearing with the first and second axles and locked by the clutch member to prevent differential motion between the first axle and the second axle.

  • Patent number: 11619291
    Abstract: A differential device is provided with: a ring gear having a tooth row arranged around an axis to mesh with an input gear; an outer case combined with the ring gear and rotatable about the axis; an inner case rotatable about the axis relative to the outer case and having a toothed end with axially projecting dog teeth; a differential gear set supported by the inner case and to be coupled with a pair of axles to allow differential motion between the axles; a clutch member engaging with the outer case and disconnectably connecting with the dog teeth so as to prevent the inner case from rotating relative to the outer case; and perforations penetrating the outer case and opened on an outer face of the outer case, the perforations being so disposed as to expose the dog teeth radially outwardly from the outer case.

  • Patent number: 7757464
    Abstract: A method for manufacturing electronic or electric products such as flat-panel display devices, for coping with change or variations of dimensions of the products and for curbing damage or fracture on the products and reducing recovery cost for containers, according to one embodiment, comprising; sequentially placing first flat electronic or electric products as to be sandwiched by a resin-sheet band formed of one or pair of band-shaped flat resin sheet and as to be arrayed in a row; forming joined areas by bonding faces of the resin-sheet band as to form receptacles respectively for the first flat electronic or electric products; thus forming a band-shaped package; and then transporting or storing such array of the first flat electronic or electric products in the band-shaped package as to be used for producing second electronic or electric products.

  • Patent number: 6482892
    Abstract: An olefinic thermoplastic elastomer composition which does not exhibit problems due to a softening agent such as an oil is superior in molding processability. The thermoplastic elastomer composition is produced by a heat crosslinking process of a resin-rubber composition that contains an olefinic and/or diene rubber, an olefinic resin, and a vinyl copolymer. The vinyl copolymer is obtained by copolymerizing 20 wt % or more of a vinyl monomer represented by CH2═CHOCOR1 or CH2═CHOR2 wherein R1 and R2 are alkyl groups having 1-6 carbon atoms. The thermoplastic elastomer composition can include a vinyl copolymer that has not undergone a heat crosslinking process.
