摘要:
The present invention provides a surface acoustic wave device comprising an electrode 8 to serve as an interdigital transducer, the electrode 8 including a bottom Ti layer 2, Al alloy layer 3, upper Ti layer 4, and Al alloy layer 7 which are superposed one after another on a surface of a piezoelectric substrate 1. A thickness A of the bottom Ti layer 2 is greater than a thickness C of the upper Ti layer, and is not less than 50 nm nor more than 120 nm. The sum of the thickness A of the bottom Ti layer 2 and the thickness C of the upper Ti layer 4 is less than 150 nm. Accordingly, with the surface acoustic wave device, occurrence of migration is inhibited to obtain a higher durability than conventionally.

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.

摘要:
A head actuator for a disk drive is provided with a structural body integrally formed by a housing portion for rotatably supporting a moving part formed by a head for writing/reading data in/from a disk and a coil fixed therewith and a yoke portion for interlinking magnetic flux with the coil, which structural body is fixed to a base portion. By virtue of such structure, the resonance point of a vibration system of the head actuator can be increased in frequency thereby to stably and correctly locate the head on the disk. The structural body and base portion mount to each other on the surfaces which are substantially coplanar with the center of gravity and head arm direction of movement.
摘要:
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.
摘要:
In a liquid crystal panel, a scanning electrode is formed on an upper substrate, and a scanning electrode terminal, a data electrode, and a data electrode terminal are formed on a lower substrate. The scanning electrode and the data electrode are opposed to each other via a liquid crystal material. Conducting members which are disposed in a sealing member and have conductivity are sandwiched between the scanning electrode and the scanning electrode terminal. Ac voltage is applied from the scanning electrode terminal and the data electrode terminal so as to apply ac voltage between the scanning electrode and the scanning electrode terminal via the data electrode and the liquid crystal material, thereby correcting a conduction defect on the conducting part. This method makes it possible to correct a conduction defect on a conducting member in a liquid crystal display device, which is provided with the conducting part between the substrates, so as to improve display quality and a yield of the liquid crystal display device.
