Electrostatic capacity-type pressure sensor with reduced variation in

A multi-layer circuit board capable of reducing an electrical resistance between circuit patterns positioned inside the circuit board and a through-hole connection conductor. A plurality of circuit patterns are superposed on each other with a plurality of insulating layers being alternately interposed therebetween in turn. A solution in which ultrafine metal particles of the independent dispersion type such as silver, gold, palladium or the like are contained in a colloid-like manner is applied so as to extend from one of lands through an inner surface of a through-hole to the other land. Then, the solution is calcined to form a metal particle film, The metal particle film is coated thereon with a conductive paste such as a resin/silver paste or the like, which is then calcined to form a conductive paste layer.

Process for manufacturing a multi-layer circuit board

A printed capacitor-mounted circuit board capable of increasing a capacity of each of printed capacitors formed on a printed board. A copper-clad laminate is arranged so as to act as an insulating substrate. The printed capacitors each include a first electrode made of a copper foil and arranged on a front surface of the copper-clad laminate. Then, a dielectric layer made of a dielectric paste is arranged on the first electrode and a second electrode made of a conductive paint is arranged on the dielectric layer.

Capacitor-mounted circuit board

A practice apparatus for a swing type athletic equipment capable of permitting a practicer to accurately know a locus of a ball hit. A triaxial acceleration sensor is mounted in a head of a golf club. Acceleration data in three detection-axis directions outputted from the triaxial acceleration sensor are transmitted to a data processing unit through a data transmission unit arranged in the grip. The data processing unit analyzes a locus of a golf ball hit and swing thereof based on the acceleration data. Results of the analysis are displayed on a monitor.
