Title: Boiler
Inventor: KANEKO SHIYOUZOU
IPC: F23C6/04
Filed: 1982-01-13
Abstract: PURPOSE:To enable to inhibit generation of NOx and to prevent excessive growth of ash, as well as to decrease unburnt content in ash formed from various kinds and classes of coal, by downwardly expanding the volume of a refractory combustion chamber, and by performing two-stage combustion in the combustion furnace of a boiler. CONSTITUTION:The fuel, injected from burner ports which are provided in the lower combustion chamber 11, forms flames 22 on burners 14, downwardly burning, and long flames can be held on the burners 14, having good ignitability by receiving radiant heat radiated from insulating and refractory inner wall of a combustion chamber. The flames 22 turn back in U-form, so that they can secure resident time as about two times long as in the same height of a furnace, and unburnt content in flames can be minimized. The flames get into a middle furnace 13, of which sectional area is smaller, from the lower combustion chamber 11, and is sufficiently mixed. In this state, denitrifying fuel is injected from a fuel injection burner 15, and NOx is eliminated. In addition, superheaters 18 are provided in the upper furnace 17, which has a wide space, so that the growth of ash deposition can be prevented.

Title: Head rest provided with air bag device
Inventor: URASAKI YOSHIO
IPC: B60R21/207
Filed: 1992-01-10
Abstract: PURPOSE:To lessen the load imposed on the neck, etc., by a method wherein in the case of a collision from behind, an air bag of an air bag module built in a head rest is inflated forward, and in the case of a frontal collision, it is inflated later than a main air bag. CONSTITUTION:Base ends of head rest stays 3 are fixed to a seat back frame 5 and the upper ends are in a head rest 1 to which an air bag module 7 is attached. When a vehicle collides from behind and receives an acceleration higher than the specified limit, at least one of sensors detects it and conducts. As a result, an electric signal is input to an inflator of the air bag module 7 to bring the inflator into action, causing an air bag to inflate forward. In addition, when a frontal impact higher than 30km/h works, a signal is generated from a vehicle speed detecting sensor and an AND-gate generates a signal, so that the air bag is delayed 10msec to act by a delay circuit. The head of a passenger is sandwiched between the air bag and a main air bag to protect the head and neck.

Title: Production of high-strength steel of superior workability
Inventor: YUZUTORI TAKAAKI
IPC: C21D8/00
Filed: 1981-01-12
Abstract: PURPOSE: To produce a high-strength steel of improved weldability by working a low C-content steel at ≥30% reduction of area in a temp. range of Ar 3  below prescribed temp., and quickly cooling the same in a phase deposition region on the way of cooling thereby providing the two-phase-layerlike structure of ferrite + martensite.  
     CONSTITUTION: A steel contg. 0.005W0.2% C, 0.3W2.5% Mn and ≤1.0% Si, respectively, is worked at Ar 3  point below 930°C within a temp. range at which austenite grains are fined and the recrystallization progression of austenite stagnates considerably and at ≥30% reduction of area. Next, in the ferrite phase deposition temp. region on the way of cooling of the steel after said cooling, C is thickened in the untransformed austenite phase along with the deposition of ferrite phase. After 5W60% deposition as ferrite phase, the untransformed austenite of a high C concn. is quickly cooled, whereby the two-phase-layerlike structure of fine ferrite particles and martensite of a high apparent C concn. is obtained. As a result, the high-toughness, high-tensile steel of superior cold workability having ≥50kg/mm 2  tensile strength is obtained.
