PURPOSE:To manufacture a multi-layer printed wiring board whose electric characteristics are excellent by eliminating generation of an air void, by applying heating and press molding in a vacuum. CONSTITUTION:Prepregs 13 are arranged among a large number of printed wiring boards 12a-12c. Mold release film sheets 14, 14 are arranged respectively on the top side of the printed wiring board 12a and u...

PURPOSE:To make it possible to shorten the time of gear shift of an automatic speed change gear having no synchronizing mechanism, by abruptly decreasing the rotational speed of an engine with the use of an exhaust brake during high load operation in accordance with the detected torque value of the output side. CONSTITUTION:In an automatic speed change gear, a shift valve 17 actuates selector valv...

PURPOSE:To effectively prevent an engine from stopping, by detecting the increasing speed of control force of a brake in order to determine that the operation of brake falls in a panic brake condition when the detected increasing speed exceeds a set value, thereby a clutch is rapidly disengaged. CONSTITUTION:During a vehicle running, when a brake pedal 12 is depressed, and an air-pressure switch S...

PURPOSE:To easily produce a long-sized superconductive wire by passing a superconductive wire into the melt of an oxygen free copper to from a superconductive composite wire having an oxygen free copper coating layer and reducing diametrally such wire then packing many pieces thereof into an oxygen free copper pipe and reducing again diametrally the wires. CONSTITUTION:The long-sized material of t...

In a pressure transducer of the piezoelectric type, a resonator (10) is made up of a pellet (16) mounted inside an element designed to be subjected to the action of a pressure on its exterior face (18). The pellet (16) and the element (12) are cut in the same quartz block, using a cut which provides two vibration modes. The forces resulting from the external pressure are transmitted to the edge of...

A resonant tag circuit with at least one resonant frequency operates in an electronic security system in which the tag circuit is detected and electronically deactivated in order to destroy the resonant characteristics of the tag circuit at the detection frequency. The tag circuit is designed with capacitor plates 10, 12, 22, 24 which are located closer to one another at a selected point 20, 32. I...
