An audio playing apparatus that plays a multiplexed audio stream resulting from the multiplexing of multiple kinds of audio is disclosed. The apparatus can be switched at least between a mixing output mode for mixing decoded data or uncompressed data of the audio streams of multiple kinds of audio and outputting the result to one audio output terminal and a separate output mode for outputting the audio streams of multiple kinds of audio to separate audio output terminals independently.

A connecting rod is formed by cold forging in a single pressing cycle at a good accuracy without separately preparing a large-end cap, to thereby reduce the manufacturing cost. A double-action type of forging apparatus is made up of an upper die, a lower die, and a large-end portion punch and a small-end portion punch, both being movably provided in each of the dies. The upper die is closed to the lower die while forging a preform, to thereby roughly form a connecting rod. Then, the large-end portion punch and the small-end portion punch are protruded into a forming space between both the upper and lower dies to forge the parts to be pierced, thereby filling underfilled parts with material. Then, the large-end portion punch and the small-end portion punch on the side of the upper die are pushed out of the forming space to reach the lower die. The underfills left in the parts to be pierced are blanked or punched away to form a large-end hole and a small-end hole.

A capacitive pressure sensor is provided which is capable of highly accurately and reliably measuring pressure over a wide range from an extremely low level to a high level without being affected by environmental changes. The capacitive pressure sensor is constructed of a first diaphragm; a second diaphragm arranged in parallel with the first diagram; a diaphragm support arranged between the first and second diaphragms for supporting the first and second diaphragms along the periphery thereof to define a space isolated from the outside; a plurality of pillars having respective ends fixed on the opposing surfaces of the first and second diaphragms for securely supporting the first and second diaphragms; a movable electrode formed on one of the opposing surfaces of the first and second diaphragms; and a fixed electrode formed in the space without contacting with the plurality of pillars and securely supported by the diaphragm support. Pressure values measured by the capacitive pressure sensor are substantially free from errors due to fluctuations in atmospheric pressure and errors caused by aging changes of residual stress on the bonding interface.

When an actuator is operated, an upper die is displaced downwardly, pressing a lower surface of a workpiece against a forming surface. After the upper die is displaced upwardly, an ejecting member is displaced upwardly to push the workpiece upwardly by a lower die. As the workpiece is displaced upwardly, an outer circumferential surface of the workpiece is squeezed by a squeezer projecting radially inwardly from an inner circumferential surface of an outer ring.

A loading mechanism of this invention that draws a card into a body unit and ejects the card outside of the body unit is so constructed as to include a movement member that moves to a drawing direction and an ejecting direction of the card by means of power of a drive motor, and an engagement member provided to the movement member so as to engage with and disengage from a recess of the card. In this construction, the engagement member is engaged with a recess of the card to thereby move the card together with the movement member to the drawing direction and the ejecting direction.

An electrostatic capacity-type pressure sensor includes a diaphragm support body, first and second lids, a fixed electrode, a coupling member, an electrode support member, and a movable electrode. The diaphragm support body is formed into a tube shape. The first and second lids have thin diaphragm portions and thick fixing portions formed integrally with peripheral edge portions of the diaphragm portions and are arranged to face each other by bringing the fixing portions in tight contact with the two end portions of the diaphragm support body. The first and second lids separate the interior of the diaphragm support body from the outside by closing the two end portions of the diaphragm support body. The fixed electrode is formed on the inner surface of the fixing portion of at least one of the first and second lids. The coupling member has two ends respectively connected to the first and second lids to couple the diaphragm portions facing each other. The electrode support member is supported by the coupling member and arranged between the first and second lids at a predetermined interval. The movable electrode is formed on the electrode support member so as to face the fixed electrode. The movable electrode and the fixed electrodes are arranged parallel to each other at a predetermined interval to constitute a capacitor.

A valve device secured to a multi-layer substrate provided with an electrical wire and a flow path for a fluid includes a diaphragm disposed at a location allowing the flow path to be opened and closed, a stepping motor causing the flow path to be opened and closed by reciprocating the diaphragm, and a base holding the diaphragm while the diaphragm is interposed between the base and the multi-layer substrate when securing the valve device to the multi-layer substrate. In the valve device, a terminal electrically joined to the electrical wire is provided near a securing surface where the valve device is secured to the multi-layer substrate.

An optical transmission line system includes a first optical transmission line equipment having a pair of a first optical signal transmission unit and a first optical signal reception unit, and a second optical transmission line equipment having second optical signal transmission and reception units which are connected to the first optical signal transmission and reception units through downstream and upstream optical transmission lines. When light stoppage is detected by the optical signal reception unit due to the occurrence of a disconnection or other breakage in the optical transmission lines, a corresponding optical signal transmission unit reduces the transmission level of the light transmission signal to a level harmless to the human eye. In order to reduce the level of transmission, the optical signal transmission unit converts all the main signal data bits to "0" and sends only the small number of supervisory information bits to the optical signal reception unit of the other side. The optical signal reception unit operates so as to reduce the level of transmission of the optical signal transmission unit forming a pair with that unit.
