Abstract: A vehicle seat device capable of suitably restraining an occupant by means of a seat belt device includes a seat main body having a seat cushion and a seat back, a reclining device connecting the seat back to the seat cushion so as to be pivotable and capable of locking a pivoting motion of the seat back, and a seat belt device for restraining an occupant seated on the seat main body. The seat belt device includes a lap belt restraining the occupant's lumbar or thighs, a belt anchor attached at a position beside the seat main body and having a belt engaging portion engaging with an engaged portion provided in a tip portion of the lap belt, and an anchor moving device capable of moving the belt engaging portion of the belt anchor in a seat front to back direction with respect to the seat main body.

Abstract: An occupant protection apparatus includes: a vehicle seat arranged in an inner space of a side wall of a vehicle; a side airbag device provided in the side wall or the vehicle seat and including a side airbag to be inflated and deployed between the side wall and the vehicle seat. The vehicle seat includes: a pressure-receiving portion to receive a load from an occupant seated on the vehicle seat; and a frame to support the pressure-receiving portion. The occupant protection apparatus further comprising an electronic control circuit configured to perform moving the pressure-receiving portion so that the occupant is pushed away from the side wall before the occupant comes into contact with the side airbag at an activation time when the side airbag device is activated by an impact acting on the side wall from an outside of the vehicle and the side airbag is inflated and deployed.

Abstract: A pulse rocket motor has a hollow cylinder-like first grain situated in a rear section of a pressure vessel; a first igniter for igniting the first grain; a hollow cylinder-like second grain situated in a front section of the pressure vessel; a second igniter for igniting the second grain; and a dividing sheet member that covers the second grain within the pressure vessel. The dividing sheet member includes a dividing sheet expanding at least along the inner circumferential surface of the second grain and holders formed integrally with the dividing sheet at both ends of the dividing sheet by cure adhesion and attached to the pressure vessel. The dividing sheet includes a brittle portion that expands along the inner circumferential surface of the second grain through a rear end face of the second grain and is more brittle than other portions.

Abstract: A transmitting and receiving apparatus for satellite communications, whose sizes of signal processing and apparatus are not made to be large, and which can make the transmission delay minimum caused by retransmission and is easy to be carried and installed, is provided. The transmitting and receiving apparatus for satellite communications provides a transmitting data collision detector, a first random access controller and a second random access controller. When the transmitting data collision detector detects collision of a transmitting packet data signal “Sb” transmitted through the first random access controller and a transmitting packet data signal “Sd” transmitted through the second random access controller, the transmitting data collision detector outputs a collision detecting signal to the second random access controller.

Abstract: A satellite packet communication system comprising a central station and VSAT stations. The central station generates chip-rate clock pulses and transmits a series of data on timeslots of a frame to a satellite transponder, and a plurality of terminal stations. Each VSAT station receives the frame from the transponder and recovers the chip-rate clock pulses from the received frame. A pseudorandom number (PN) sequence generator, provided in the terminal station is synchronized with the recovered chip-rate clock pulses for generating bits of a PN sequence with which packetized data bits are pseudorandomly modulated and transmitted in burst form to the transponder. The central station includes a correlator which is synchronized with the central station's chip-rate clock pulses to detect correlations between the pseudorandomly modulated data bits a sequence of pseudorandom numbers corresponding to the PN sequence bits of the terminal stations.
