Patent number: 9620267Abstract: In a method of manufacturing a resistor, a sheet-shaped resistive element having formed thereon a plurality of belt-shaped electrodes is cut in a direction crossing these belt-shaped electrodes to produce strip-shaped resistive elements. On the other hand, a metal paste containing a glass frit is printed in a pattern of belts arranged at regular intervals on a surface of a plate-shaped insulating substrate to form a plurality of adhesive layers. Then, the strip-shaped resistive elements are respectively applied to the adhesive layers on the plate-shaped insulating substrate, and these are fired in a nitrogen atmosphere. After firing, while a resistance value of a part between each adjacent two electrodes of each strip-shaped resistive element is measured, the strip-shaped resistive element is trimmed so that the resistance value becomes a predetermined value. Then, the plate-shaped insulating substrate having adhered thereto the strip-shaped resistive elements is divided into pieces.Type: GrantFiled: April 1, 2014Date of Patent: April 11, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Seiji Tsuda, Shoji Hoshitoku, Takeshi Iseki, Kazutosi Matumura

Patent number: 9001485Abstract: An overvoltage protector includes a first discharging electrode, a second discharging electrode, and an overvoltage protection part provided between the first and second discharging electrodes. The overvoltage protecting part has an insulating property under a normal operation condition, and has a conductive property if an overvoltage is applied between the first and second discharging electrodes. The overvoltage protecting part is made of a mixture of resin having an insulation property, an inorganic compound having an insulating property, and metallic boride compound powder. The metallic boride compound powder has a high melting point therefore it is hardly melted. Under high temperatures causing the powder to melt, the powder is oxidized and loses conductivity, thus providing a high reliability.Type: GrantFiled: August 25, 2011Date of Patent: April 7, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kenji Nozoe, Hideaki Tokunaga, Takeshi Iseki, Takashi Morino, Kouichi Yoshioka

Publication number: 20100188791Abstract: A conductive layer containing gold as a main component is formed on the upper surface of an insulating base. A gap is formed on the conductive layer. A plurality of leader electrodes are formed to oppose one another via the gap. An excess voltage protection material layer is formed to cover some parts of the respective leader electrodes and the gap, so as to obtain an anti-static part. This method enables an accurate formation of a narrow gasp. Thus, it is possible to manufacture an anti-static part having a low peak voltage, stable suppression characteristic of electrostatic discharge (ESD), and a high sulfide resistance.Type: ApplicationFiled: October 19, 2007Publication date: July 29, 2010Inventors: Kenji Nozoe, Takeshi Iseki, Takashi Morino, Hideaki Tokunaga

Publication number: 20100134235Abstract: A pair of thick first electrodes (2) are formed on an upper surface of alumina substrate (1) are formed with material having a low specific resistance. Thin second electrodes (3) that are positioned between first electrodes (2) and made of material having a high melting point are formed in a thin state. A gap (4) is formed between the second electrodes (3). First electrodes (2) forming connection electrodes are prevented from producing heat and protected from damage. The width of the gap between second electrodes (3) is narrow and accurate. This provides an electrostatic discharge (ESD) protector that is resistant to repetitive application of static electricity, reduces a peak voltage, and has a stable characteristic suppressing electrostatic discharge.Type: ApplicationFiled: June 19, 2008Publication date: June 3, 2010Applicant: Panasonic CorporationInventors: Kouichi Yoshioka, Masakatsu Nawate, Takashi Morino, Kenji Nozoe, Takeshi Iseki
