Patent number: 8202594Abstract: The present invention provides a double-sided adhesive tape for fixing a decorative sheet for speaker, which includes a nonwoven fabric substrate, an acrylic pressure-sensitive adhesive layer A disposed on one side of the nonwoven fabric substrate and an acrylic pressure-sensitive adhesive layer B disposed on the other side of the nonwoven fabric substrate, in which the adhesive tape has a tensile strength in the tape flow (MD) direction of 8 N/10 mm or more and a tensile length in the width (TD) direction of 8 N/10 mm or more. The double-sided adhesive tape is excellent in the adhesion performance to a housing and a decorative sheet for speaker and at the same time, has excellent releasability ensuring that when separating the decorative sheet portion, smooth separation can be attained without leaving a residue of tape or pressure-sensitive adhesive on the housing portion.Type: GrantFiled: April 29, 2009Date of Patent: June 19, 2012Assignee: Nitto Denko CorporationInventors: Mutsumi Kobayashi, Kazuyuki Yagura

Publication number: 20110151220Abstract: A double-sided pressure-sensitive adhesive (PSA) sheet 11 has, on each side of a plastic film substrate 1, a PSA layer 3 provided through an undercoat layer 2 containing a compound having an oxazoline group. The PSA layer 3 is formed from a water-dispersed PSA composition. This PSA composition contains an acrylic polymer synthesized by emulsion polymerization of a monomer raw material containing an alkyl(meth)acrylate and a carboxyl group-containing monomer, and a water-dispersed tackifier at a mass ratio of 100:5 to 100 based on solid content. The toluene emission when this PSA sheet is kept at 80° C. for 30 minutes is 20 ?g or less per gram of the sheet.Type: ApplicationFiled: December 20, 2010Publication date: June 23, 2011Applicant: NITTO DENKO CORPORATIONInventors: Mitsuyoshi SHIRAI, Akiko TAKAHASHI, Shouhei WADA, Mutsumi KOBAYASHI

Publication number: 20100021668Abstract: The invention relates to a double-sided pressure-sensitive adhesive sheet for use in fixing a liquid-crystal display module unit to a backlight unit in a liquid-crystal display, the double-sided pressure-sensitive adhesive sheet including at least one heat-peelable pressure-sensitive adhesive layer containing heat-expandable microspheres. According to the double-sided pressure-sensitive adhesive sheet of the invention, since the pressure-sensitive adhesive layer has high adhesiveness and a liquid-crystal display module unit can be tenaciously fixed to a backlight unit with the pressure-sensitive adhesive sheet, excellent adhesion reliability can be attained. Furthermore, since this pressure-sensitive adhesive sheet can be easily made peelable by a heat treatment, it has excellent suitability for reworking.Type: ApplicationFiled: November 26, 2007Publication date: January 28, 2010Applicant: NITTO DENKO CORPORATIONInventors: Daisuke Shimokawa, Mutsumi Kobayashi

Patent number: 6894520Abstract: A CBCM measurement device includes a PMIS transistor, an NMIS transistor, a first reference conductor section connected to a first node, a second reference conductor section, with a dummy capacitor being formed between the first and second reference conductor sections, a first test conductor section connected to a second node, and a second test conductor section, with a test capacitor being formed between the first and second test conductor sections. The transistors are turned ON/OFF by using control voltages V1 and V2, and the capacitance of a target capacitor in the test capacitor is measured based on currents flowing through the first and second nodes. The capacitance measurement precision is improved by, for example, increasing a dummy capacitance.Type: GrantFiled: January 31, 2003Date of Patent: May 17, 2005Assignees: Matsushita Electric Industrial Co., Ltd., Renesas Technology CorporationInventors: Kyoji Yamashita, Hiroyuki Umimoto, Mutsumi Kobayashi, Katsuhiro Ohtani, Tatsuya Kunikiyo, Katsumi Eikyu

Patent number: 6876208Abstract: It is an object to obtain a semiconductor device having a circuit for CBCM (Charge Based Capacitance Measurement) which can measure a capacitance value with high precision. An MOS transistor constituting a circuit for CBCM has the following structure. More specifically, source-drain regions (4) and (4?) are selectively formed in a surface of a body region (16), and extension regions (5) and (5?) are extended from tip portions of the source-drain regions (4) and (4?) opposed to each other, respectively. A gate insulating film 7 is formed between the source-drain regions (4) and (4?) including the extension regions (5) and (5?) and a gate electrode (8) is formed on the gate insulating film (7).
