Title: Polymer dispersion solution, method of manufacturing and its application
Inventor: TANAKA KATSUTOSHI
IPC: C08F220/06
Filed: 1997-11-04
Granted: 2001-05-16
Abstract: This invention describes the manufacture method of a polymer dispersion solution of a (methyl)acrylic acid (co)polymer. Polymerization takes place in an aqueous solution containing water-soluble monomer of the (methyl)acrylic acid. The monomers to be polymerized include 15-100 mol% of (methyl)acrylic acid and 0-85 mol% of non-ionic monomers. The (methyl)acrylic acid is selected from acrylic acid, methylacrylic acid and their mixture, while the non-ionic monomer is selected from acrylic amide, acrylcyanide, methyl methylacrylate ester, ethyl methacrylate ester, vinyl methyl ether, vinyl acetate salts and their mixtures. The temperature employed for the polymerization system is between 0-100 DEG C. During the preparation of the (methyl)acrylic acid (co)polymer dispersion solution, stirring has to be gentle with a speed greater than 1 m/min in the presence of polymeric electrolyte that containing dispersive retaining agent. The weight ratio between the (methyl)acrylic acid water-soluble monomer and the agent is approximately between 100:1 and 10:1. In the polymer dispersion solution, there are at least 5 wt.% of the (methyl)acrylic acid (co)polymer containing (methyl)acrylic acid polymer particles whose average particle diameter is 1-100 mu m while theviscosity of the polymer dispersion solution is 10-3000 cp within one month after production. The polymer particles can be observed if diluted 10 times with distilled water and under a microscope at 400 times magnitude and can dissolve into an aqueous solution if adding an alkali to the diluted solution and adjusted the pH to 7.0. This dispersion solution can be used in paper-making, improvement of soil water content, prevention of inner layer falling and coagulation of solid suspension. This dispersion solution is characterized by its low viscosity, good application property and storage stability.

Title: Packaged body and production method therefor
Inventor: BANDO TAKESHI
IPC: B65D33/04
Filed: 1997-11-28
Granted: 1999-12-11
Abstract: To make it difficult for an opening piece to be separated from a packaging material and to eliminate the necessity to match position for joining the opening piece during use. This package bag is so made that a packaging material Fa and a packaging material Fb are laminated by an adhesive layer 6 at it width measurement A part. An opening part 8 is formed in the inner packaging material Fb of the laminated part, and an opening flap 9 detachable by a cutting C is formed in the outer packaging material Fa. Because the opening flap 9 is integral with the packaging material Fa, the material cost for this package bag is less than that using a separate cover material. In addition, because the packaged body uses 2 packaging material sheets Fa and Fb laminated, the same can be formed in an ordinal packaging process, and the production is easy.

Title: Extending asynchronous transfer mode (ATM) QOS across local area networks
Inventor: ELLINGTON WILLIAM W
IPC: H04L12/56
Filed: 1998-06-08
Granted: 2000-04-11
Abstract: Asynchronous Transfer Mode (ATM) network Quality of Service (QoS) guarantees are extended to Token Ring LAN stations. A LAN station originating a request for a connection through an ATM network to either a remote ATM station or a remote LAN station sends a frame having an encoded priority value to a LAN/ATM interface device. The device maps the priority value to one of the standard ATM traffic classes; namely, CBR, VBR,ABR and UBR. The LAN/ATM interface device attempts to set up a connection through the ATM network conforming to the mapped class or QoS. If the connection destination is another LAN station, a destination LAN/ATM interface device attempts to set up the final STM-LAN phase of the connection.

Title: Polymer particularly suitable for use as photoresist and photoresist composition
Inventor: MCCULLOCH IAIN
IPC: H01L21/027
Filed: 1999-05-05
Granted: 2002-02-21
Abstract: A water soluble polymer that when used with a suitable photoacid generator (PAG) forms a negative working water soluble photoresist. The polymer comprises of a backbone, such as polyvinyl ether, coupled by a linkage group to an acetal protected β-keto acid group. With the addition of a number of commercially available photo acid generators, the polymer formulation forms a negative working photoresist that is water soluble. Exposure to radiation will cause a photoacid catalyzed deprotection of the acetal group, yielding a β-keto acid which, upon heating, will undergo decarboxylation, which results in a water insoluble photoproduct and evolution of CO2 as a byproduct. This photochemically induced reaction results in a significant change in the polymer solubility parameter, and the product is no longer soluble in water. As this solubility change does not require crosslinking, there will be no swelling of the resist images on exposure to the aqueous base during development, and hence no loss of resolution. This enables the photoresist to be used at fine resolutions at i-line and deep UV wavelengths.

The hole-brink of these open holes, which is close to the outer-wall face that is opposite to the insulating main body is designed to have a curved surface. The recessed slots exhibiting in vertical-length direction are disposed on both outer sidewalls of the insulating main body. Protruding rib is installed at the position corresponding to each terminal in these recessed slots. By installing structures such as opening holes and recessed slots, the insulating main body is made to be able to use mold for providing terminal position basis during the ejection formation of the insulating main body. Therefore, the yield after the formation can be effectively raised.
