A pressure sensor into which the internal pressure of a fuel tank is introduced through a nipple portion and the atmospheric pressure is introduced through an atmosphere introducing hole, and a pressure difference between the internal pressure and the atmospheric pressure is detected by a diaphragm, comprises a check valve provided in the nipple portion to prevent fuel from leaking out to the atmospheric side. A pressure buffer chamber in the nipple portion of the pressure sensor is provided in which a ball is installed. A bottom face of the pressure buffer chamber is formed to be concave, and a receiving seat for receiving the ball is provided on the bottom face. Therefore, no fuel leaks outside, even when the vehicle comes across an accident and overturns sideways under the condition that the diaphragm used as a sensor element is fractured in the measurement of internal pressure of the fuel tank.

Sub core sections are arranged at the end portions and the center portion of a stator core, and strand conductors are twisted and transposed by 360 degrees continuously toward the extending direction of winding slot. The length corresponding to transposition pitch 180 degrees of the strand conductors of the stator core is set as one core unit area, the sub core sections including portions whose space factors are different are arranged such that the sum of voltages in the strands induced in the strand conductors in the odd-numbered core unit area from one end portion of the stator core offsets the sum of voltages in the strands induced in the strand conductors in the even-numbered core unit area from the end portion of the core.

Audio data and additional audio information multiplexed therewith and distributed are received by an integrated receiver decoder. The received audio data is separated and decoded by a received-signal processing section. The data is then sent to an external recording unit and recorded onto a recording medium. The received additional audio information is separated by the received-signal processing section. The title of a musical piece and performer information are sent to the external recording unit through a digital interface or an infrared interface, and written onto a predetermined area of the recording medium.

A dielectric constant sensing device of the present invention comprises a transmission line consisting of a first electrode formed of a conductor being wound like a longitudinal cylinder, a second electrode provided to be separated from the cylindrical surface of the first electrode at a predetermined distance, and a chamber for introducing a measured fluid between the first electrode and the second electrode, whereby a dielectric constant of the measured fluid can be sensed based on a rate of a pulse voltage wave propagated over the transmission line. Accordingly, the fluid dielectric constant sensing device which is able to attain high precision by a simple structure can be provided.

A pressure difference detector for detecting a pressure difference between atmospheric pressure and a fuel system vapor pressure to be measured, includes a pressure dampening member 17a for dampening the flow of atmospheric air between an introducing inlet 11a and a reference pressure chamber 12 to limit the air flow rate to a value smaller than a leakage flow rate between the chamber and a fuel system vapor pressure introducing inlet 11b due to a leaking 0 ring seal. This prevents an erroneous judgment that the fuel system is leaking.

Information storage mediums such as video discs and digital audio discs are fabricated by extruding a mass of electrically conductive synthetic resin into a block assembly composed of a pair of separable blocks in which the mass is molded into a cake that is then carried by one of the blocks as separated into a press in which the cake is pressed into an information storage medium or disc blank. The blank is transferred into a trimmer for trimming an overflow off the disc blank as an annular scrap, which is in turn chopped by a chopper into pieces for reuse. A disc from which the scrap has been removed is fed to a hot stamping machine in which an identification foil piece is attached with heat to the disc. The disc with the foil piece stamped thereon is punched to form a central hole by a punching machine. A predetermined number of such finished discs are stacked on a pallet in a stacker, with partition plates alternating with groups of such piled discs, and the pallet loaded with the discs is discharged from the stacker.
