Abstract: The present invention provides an airbag device that is capable of restraining a rectification cloth that switches a vent hole to an opened or closed state so as not to be twisted, and that is capable of switching the vent hole from an opened state to a closed state, and further, switching to the opened state. At an initial stage at which an airbag main body inflates and expands, the vent hole 8 is arranged between the leg portions 5, and when the airbag main body is in a predetermined internal pressure state, the vent hole is closed by means of the band-shaped portion 4. If an occupant or the like comes into contact with the airbag main body, a tense state of each of the leg portions is released, the rectification cloth is established in a slackened state, and the vent hole 8 is established in an opened state.

Abstract: An ATM switch allowing simplified OAM processing only on the line incoming side is disclosed. An incoming line circuit has a header conversion table storing information indicating whether the system is an end point of an OAM processing flow for each connection and an OAM table storing an AIS flag and an RDI flag for each connection. As for an OAM cell found by referring to these tables to be forced to go back to its own port, an switch output port number is rewritten in the OAM function section. In addition, in the case of an AIS cell, the function type is rewritten so as to become an RDI cell. In the case of an LB cell, the LB indication is rewritten so as to become a return LB cell, and switching to its own port is conducted in the ATM switch core.

Abstract: An airbag, which is folded and assembled elongatedly, is deployed along a side window. The airbag has a folded portion and a pleated portion which wraps the folded portion under the assembled condition. The airbag also has an inner tube which is provided from the inside of an infusion portion to the inside of an upstream portion of an inflating portion. The inner tube prevents that the airbag is damaged by heat of inflation gas. When the airbag is assembled, the inner tube is positioned along a first fabric, which is developed so that the surface of the first fabric faces an inside of a vehicle compartment, by the infused fluid. Deployment performance of the airbag (curtain airbag deploying along a side window of an automobile) is improved.

Abstract: When manufacturing a seamless pipe by carrying out elongation rolling and sizing on a mother tube for forming a seamless pipe, the occurrence of portions of thickness variation in the seamless pipe is suppressed by previously identifying the portions of wall thickness variation where the thickness varies in the circumferential direction of the seamless pipe, and carrying out elongation rolling so that the thickness of the portions of the mother tube corresponding to the portions of wall thickness variation of the seamless pipe are different in thickness at the completion of elongation rolling from that of other portions of the mother tube. As a result, local variations in wall thickness in the circumferential direction of a seamless pipe are prevented.

Abstract: An ATM cell buffer read control system prevents over-rate due to excessive use of an extra line capacity with guarantee of a minimum output rate in a WRR system. The ATM cell buffer read control system effectively uses a band by distributing an extra band with a ratio of number of ATM cell number per connection with guarantee of minimum output band per connection according to preliminarily set ratio of output ATM cell number per a given period. The ATM cell buffer read control system makes judgment whether the output band after distribution of the extra band falls within a reference output range.

Abstract: A temperature-compensated piezoelectric oscillator includes a voltage-controlled piezoelectric oscillator, a first frequency divider, a second frequency divider, and a controller. The voltage-controlled piezoelectric oscillator has an output frequency controlled by a control voltage and oscillates the output frequency having a center frequency f.sub.0 at an ambient temperature of t.sub.0. The first frequency divider frequency-divides the output frequency from the voltage-controlled piezoelectric oscillator by N to output a first divided output frequency. The second frequency divider frequency-divides the output frequency from the voltage-controlled piezoelectric oscillator by M to output a second divided output frequency. The controller controls the control voltage to be applied to the voltage-controlled piezoelectric oscillator on the basis of a frequency difference between the first and second divided output frequencies upon a variation in ambient temperature of t.sub.
