Patent number: 6187128Abstract: A labeling apparatus for converting base label stock to releasably-lined labels. The apparatus includes a vacuum anvil roller and an idler roller which cooperate to separate the base stock into its face web and backing liner components. A cutting roller cooperates with the vacuum anvil roller to butt cut the unlined face web to form butt cut labels. A traction nip roller cooperates with the vacuum anvil roller to press the butt cut labels to the backing liner to form the releasably-lined labels. The releasably-lined labels may be imprinted and the backing liner removed as the label is affixed to an article using conventional labeling equipment. A rewind nip roller cooperates with the traction nip roller to pull the backing liner, which is then rolled on a rewind mandril. The apparatus does not weaken or cut the backing liner during conversion to releasably-lined labels, because the butt cut is made after the face web is separated from the backing liner.Type: GrantFiled: January 21, 1998Date of Patent: February 13, 2001Assignee: CCL Label Inc.Inventor: Marc F. Oosterlinck

Patent number: 6186206Abstract: Preventing simply and firmly occurrence of a puncture caused by mutual contact of wall faces of a tube. Thick wall portions are formed at portions of a tube included in a tire and the thick wall portions are brought into contact with thin wall portions when the tire engages on a hazard and the tire and the tube are squeezed between flange portions of a rim and the hazard. The thick wall portions are not damaged since they have an increased strength and also the thin wall portions are protected against damage caused by a load since the load exerting on the thin wall portions is dispersed by the thick wall portions which are readily subjected to elastic deformation. The thin wall portions may be rendered thick wall portions and the thick wall portions may be brought into mutual contact.Type: GrantFiled: December 18, 1996Date of Patent: February 13, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toshio Yamagiwa, Hirohisa Takahashi, Kazuo Suzuki

Patent number: 6183837Abstract: There is disclosed a panel for use in soundproofing walls, having a base organization in which an aluminum foam board containing numerous open pores and a noise-insulating metal board are attached to either side of an aluminum honeycomb structure via adhesive sheets. The numerous open pores allow the aluminum foam board to absorb medium to high-frequency sound waves while many hexagonal cells in the aluminum honeycomb structure serve as air pockets in which resonance occurs to attenuate low-frequency noise of 500 Hz or less. Thus, with the ability of the noise-insulating metal board to prevent the propagation of sound waves, the panel can effectively absorb and block noise over a wide frequency range. The panel has the advantages of being semi-permanent in life span, highly resistant to corrosion and excellent in surface strength enough to be resistant to impact, generating neither hazardous articles nor dust, and being reusable.Type: GrantFiled: January 20, 1999Date of Patent: February 6, 2001Inventor: Tae Bong Kim

Patent number: 6183589Abstract: A method for manufacturing lead-on-chip (LOC) semiconductor packages includes steps of preparing a lead frame having inner leads and outer leads, and applying a liquid adhesive having a certain viscosity to the bottom surfaces of the inner leads. The method also includes positioning a semiconductor chip under the lead frame, to expose electrode pads through the space defined between opposing rows of inner leads. The inner leads are then attached to the active surface of the semiconductor chip by means of the liquid adhesive. The adhesive applying step may be carried out using a tool having discharge projections through which liquid adhesive is discharged from a reservoir. The liquid adhesive under the lead frame may be cured and then turned into a solid adhesive layer by thermocompression. The liquid adhesive is a thermosetting resin or a thermoplastic resin.Type: GrantFiled: March 6, 1998Date of Patent: February 6, 2001Assignee: Samsung Electronics Co., Ltd.Inventors: Shin Kim, Byung Man Kim, Il Heung Choi, Jeong Ho Bang

Patent number: 6183592Abstract: The present invention relates to assembly techniques and the resulting products which are thermally stable, have high structural integrity, and compensate for thermal stresses that occur between the various components of the package. This is accomplished, in-part, by designing the package so that the coefficient of thermal expansion (CTE) of a stiffening ring which is mounted on the package substrate matches the CTE of the substrate and optional lid. Further, the particular adhesives used to bond the stiffening ring are chosen to match their CTE to that of the substrate, ring and lid. Moreover, the substrate is designed so that its CTE, at least in-part, matches that of the chip, and also that of the stiffening ring.Type: GrantFiled: November 20, 1998Date of Patent: February 6, 2001Inventor: Mark F.

Patent number: 6174394Abstract: Polarizing coatings are formed from dyestuffs which provide a stable liquid crystalline phase in a wide range of concentrations, temperatures and pH-values. Particles formed by aggregates of the liquid crystal molecules are oriented in a predetermined direction to polarize light. The stability of the liquid crystalline state allows orienting the particles by mechanical forces such as a shearing force applied when the liquid crystal (10) is spread on a support surface (20) by a knife-like doctor (90) or a tension deformation force acting on the meniscus of the liquid crystal deposited between two surfaces (20, 30) as the surfaces are peeled off one another. As a result, the polarizing coatings are formed in some embodiments by simple methods. In some embodiments, the polarizing coatings have a high lightfastness, a high thermal stability, and a high dichroic ratio.Type: GrantFiled: December 24, 1997Date of Patent: January 16, 2001Assignee: Optiva, Inc.Inventors: Khan Ir Gvon, Yuri A.
