An improvement in a double Cardan universal joint having a pair of spiders connected by a ring-shaped coupling member, a pair of yoke members angularly movably connected with each other by the spiders, a centering assembly for aligning the yoke members with each other and defining a reservoir for grease within a bridge forming a part of one of the yoke members and a breather hole formed in the bridge for making the reservoir communicate with the atmosphere. The improvement comprises a valve of elastic material inserted in the breather hole and capable of elastically blockading the communication of the reservoir with the atmosphere when internal pressure of the reservoir is below a predetermined amount and being elastically deformed to make the reservoir communicate with the atmosphere when the internal pressure reaches or exceeds the predetermined amount.

A diagnostic system for detecting failure of rotational speed sensors incorporated in a central differential device of a four wheels drive vehicle for the purpose of controlling a lock-up clutch in the central differential device, wherein the rotational speed sensor for an output rotational member of the central differential device is checked, when the rotational speed detected thereby is lower than the rotational speed detected by the other rotational sensor, if the rotational speed detected thereby is continually zero over a period such as 10 seconds while the output of the other rotational speed sensor is above a certain low value.

In a four wheel drive vehicle, a four wheel drive device receives rotational power from an engine and provides it to the combination of the front wheels of the vehicle and also to the combination of the rear wheels of the vehicle. A device is provided for selectively coupling the rotation of the combination of the front vehicle wheels and the rotation of the combination of the rear vehicle wheels. A control device is provided for this front/rear coupling device, and includes: (a) a means for detecting the rotational speed of the combination of the front wheels of the vehicle; (b) a means for detecting the rotational speed of the combination of the rear wheels of the vehicle; and: (c) a means for controlling the front/rear coupling device, so that its operation is substantially not restricted when the discrepancy between the rotational speed of the combination of the front wheels of the vehicle and the rotational speed of the combination of the rear wheels of the vehicle is not greater than a certain threshold value; while, when the discrepancy between the rotational speed of the combination of the front wheels of the vehicle and the rotational speed of the combination of the rear wheels of the vehicle is greater than the certain threshold value, coupling between the rotation of the combination of the front vehicle wheels and the rotation of the combination of the rear vehicle wheels is substantially prohibited. The method of operation of this device is also disclosed.

Disclosed is a high speed binding device wherein a package wound with a binding thread is fixed to a flange of a flyer with its thread-winding axis in parallel with the rotation axis of said flyer and the binding thread is drawn out in the direction of the winding axis; and thereafter said binding thread is passed through a first tensioner for imparting to the binding thread a back tension decreased with a rise in the rotation speed of the flyer and then through a second tensioner for imparting to the binding thread a back tension increased with a rise in said rotation speed, thereby to cause said decrease in the back tension to be offset by said increase in the back tension, thus to bind, with a substantially constant back tension, the binding thread about the outer periphery of an element assembly passing through a through hole coaxially bored through the flyer.

A SIM comprises a substrate, an IC chip mounted on the substrate and provided with a dual interface for contact and noncontact communication, and a contact-terminal plate mounted on the substrate and provided with a plurality of contact terminals. A SIM holder for holding the SIM is provided with an antenna coil, and the antenna terminals of the IC chip are connected to terminals C4 and C8 among the eight terminals C1 to C8 of the SIM. The terminals C4 and C8 are connected to the antenna coil of the SIM holder.
摘要:
A sheet-framed IC carrier has a sheet frame having an aperature, and a backing film with a pressure-sensitive adhesive layer on one surface thereof which is adhered to the back surface of the sheet frame. An IC carrier having an IC module is secured in the aperature of the sheet frame with the adhesive layer on the backing film. When the IC carrier is removed from the sheet-framed IC carrier, no excessive load is exerted on the IC module and no projection remains on the peripheral edge of the carrier base.
