Title: Air bag
Inventor: FUJITA TETSUJI
IPC: B60R21/16
Filed: 1990-10-22
Abstract: ABSTRACT    The air bag 3 of this invention comprises a suspension string 6, which is furnished between the base cloth on the side facing to the person in the vehicle and the base cloth to be fixed on the fixed portion of car body or between the former base cloth and the fixed portion of car body.  When inflated, the shape of said air bag is maintained in the predetermined shape by said suspension string.  The suspension string 6 consists of a plurality of single strings 61 and 62, and these single strings have the sewn portions 6f to be sewn on the base cloth 3a on the side facing to said person in vehicle and all or almost all sewn portions 6f of the single strings are overlapped on each other, and these are sewn together with the base cloth 3b on the side facing to the person in vehicle.  This makes it possible to increase the strength of the sewn portions and to effectively cut the base cloth.  By overlapping the entire sewn portions, the positioning of single strings can be performed much easier.

Title: Text-to-speech system having a lexicon residing on the host processor
Inventor: GILI PATRICK R
IPC: G06F3/16
Filed: 1990-11-06
Abstract: ABSTRACT       A text-to-speech system is provided having a host system operable to perform a text-to-speech application program.  The host system includes a memory storing the lexicon for a separate text-to-speech device.  By using the host system to contain the lexicon, a sufficient amount of memory is made available.          Therefore, a very complex lexicon can be provided and more information made available to the voice synthesizer on the text-to-speech device.  This partitioning of the text-to-speech system between the host system and the text-to-speech device allows the computation-intensive processes to be performed on the text-to-speech device while providing a large memory to contain the lexicon information.

Abstract: DENTAL IMPLANT SYSTEM AND METHOD            ABSTRACT     An implant assembly and method is provided, as well as a system and method for exposing an embedded implant after osseointegration has taken place. The implant assembly comprises an implant member for embedding in the jaw and a rest factor member for securing to the implant member, the rest factor member having an upper rest surface just above the tissue level for opposing an overlying portion of a prosthesis anchored elsewhere in the jaw to form a non-retentive rest or support for accepting down pressure from the prosthesis.   The implant member is relatively short and can be installed in distal jaw regions without interference with the mandibular nerve, and has an undersurface having a shape designed for stable integration with the bone while resisting sidesway.  The method includes cutting out a bore in the jaw for receiving the implant, inserting the implant and an attached healing screw in the implant, closing the implant site and allowing osseointegration to take place over an extended period, and subsequently uncovering the implant site, removing the healing screw, and securing the rest factor member in the implant.

Filed: 1992-01-02
Abstract: The invention relates to an air release valve and more particularly to an atmospheric compensating automatic air release valve. The invention features a valve including a second orifice which is exposed to atmosphere but always shut whereby a valve mechanism in the valve is exposed to forces which are equal and opposite to a suction force which tends to hold the valve mechanism in sealing relation to the first, air release orifice. By providing first and second orifices in accordance with the present invention, then, movement of the valve float downwardly as the liquid level goes down will cause the air vent orifice to open irrespective of the pressure within the valve.      Thus, the automatic air release. valve provided in accordance with the present invention is capable of operating under virtually unlimited pressures.
