摘要:
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.

It is a method for producing a food-filled and sealed container having a high product value, in which a container lid made of resin is not deformed after sealing. In this method for producing a food-filled and sealed container, after a food is filled in a container body (10) made of thermoplastic resin, the container is sealed by heat sealing a container lid (20) made of thermoplastic resin, and the container body (10) and/or the container lid (20) have sealing surfaces (13, 24) provided with a concavity or convexity.

A device for preventing condensation of water vapor on a filling nozzle in the form of a vertical tube, included in a filling apparatus and positioned above a path of transport of containers comprises a downwardly open dry air chamber having the filling nozzle accommodated therein and permitting the container to be moved into and out of the chamber when the container is lifted by a lifter, an injection nozzle disposed as oriented downward above the path upstream from the dry air chamber for injecting dry air into the container to replace air therein, and a cover extending from a position downstream from the injection nozzle at least to the dry air chamber and covering the path from thereabove for preventing the dry air in the container from flowing out.
摘要:
A conductive layer mainly made of gold is formed on an upper surface of an insulating substrate. Plural electrodes facing each other via a gap is formed by forming the gap in the conductive layer. An overvoltage protective layer covering the gap and a portion of each of the plurality of electrodes is formed. This method can provide the gap with a narrow width precisely, and thereby, provide an electrostatic (ESD) protector with a low peak voltage, stable characteristics of suppressing electrostatic discharge, and a high resistance to sulfidation.

A chip resistor includes: a pair of upper surface electrodes formed at opposing side portions of a rectangular substrate as opposed to each other with respect to a center line of the rectangular substrate extending in a direction connecting the side portions; a resistive element formed on the rectangular substrate to be electrically connected with the upper surface electrode pair; and a pair of end surface electrodes formed on end surfaces of the opposing side portions of the rectangular substrate and electrically connected with the upper surface electrode pair. The chip resistor further includes dummy electrodes formed individually at the opposing side portions of the rectangular substrate at positions corresponding to the upper surface electrode pair in the direction connecting the side portions.

An ultrasonic sealing apparatus is provided with an excellent sealability. The apparatus is capable of supplying sufficient output energy delivered by an ultrasonic wave-generating device to a thermoplastic resin of a packing material. A tubular packing material is evenly pressed on an appropriate timing in transverse sealing so that the thermoplastic resin is sufficiently softened/melted for an excellent sealing.

The invention relates to glaze resistors which are used for electronic parts of hybrid integrated circuit devices, chip resistors, resistor network, etc. The glaze resistor comprises 4.0 to 70.0 wt % of a conductive component composed of a metal silicide and a metal boride and 30.0 to 96.0 wt % of glass in which a rate of said metal boride is 1.0 to 68.0 wt %. Thus, the glaze resistor can be formed by sintering in a non-oxidizing atmosphere and can provide a circuit, together with conductor pattern of base metals such as Cu.
