Title: Structure of combustion chamber for subchamber type engine
Inventor: SEKIYAMA YOSHIO
IPC: F02B19/18
Filed: 1991-03-30
Abstract: PURPOSE:To provide a structure of the combustion chamber of a subchamber type engine to make flames and a mixture which have burnt primarily in a subchamber smoothly flow into a main chamber. CONSTITUTION:The combustion chamber of this subchamber type engine is constructed so as to introduce flames and a mixture blown out through a connecting hole 9 formed in a subchamber 2 into a main chamber 1 having a combustion chamber opening 18 formed of a sharp tip-shaped lip part 20 through a gap passage 8 formed in a piston head 4. Combustion gas blown out of the subchamber 2 can therefore be prevented from interfering with combustion gas flowing out on account of an inverse squish flow from the main chamber 1. Thus primary combustion is finely carried out in the subchamber 2, and the secondary mixing of the combustion gas and fresh air can be accomplished in a short time in the main chamber 1 for excellent secondary combustion, and the combustion gas and the fresh air then flow from the main chamber 1 into a cylinder chamber 12 on account of the inverse squish flow, and finely accomplish the third mixing for their third combustion and finish the combustion. Thus the combustion is improved for controlling the occurrence of HC, NOX and moreover improving the performance of the engine.

Title: Optical element
Inventor: YUASA SATOSHI
IPC: G09F9/30
Filed: 1985-04-30
Abstract: PURPOSE:To obtain a distinct image having high contrast and resolution and to eliminate the limitation in angle of field by sandwiching a liquid layer contg. a surface active agent having a cloud point between a pair of substrates formed with heating elements on the surface of at least one substrate. CONSTITUTION:The liquid layer 2 has transparency in the state (the state below the cloud point) in which the liquid layer 2 is not heated and therefore the incident ray 6-1 on the low-temp. region 4 of the liquid layer 2 passes approximately straightly through the liquid layer 2 and is emitted from the substrate 1. On the other hand, the liquid layer 2 in the region in contact with or proximity to the heated part is also heated to the cloud point or above and the liquid layer 2 exhibits non-transparency when the prescribed position of an IR absorption layer 8 is heated from the outside by the irradiation of, for example, an IR beam 5 according to an information signal. The incident ray 6-2 on the heated region 4a scatters (diffuses) consequently. The heated region 4a restores the original transparency when the temp. falls.

Filed: 1994-04-28
Abstract: PURPOSE:To improve the quality of a cast slab at the part of starting casting by presetting aluminum particles at least near an immersion nozzle tuyere in a tundish just before supplying molten steel into the tundish from a ladle, at the time of continuously casting a stainless steel. CONSTITUTION:As the aluminum particles 8 are set at least near the tuyere 5a of the immersion nozzle 5 in the tundish, the aluminum is reacted with the remained air, etc., in the tundish and deoxidized at the time of starting the supply of the molten steel from the ladle, and thus, oxygen concn. in the steel is not made to be high. Further, as the exothermic reaction is developed at the time of oxidizing the aluminum, the molten steel is difficult to drop the temp., even at the initial time of supplying the molten steel whose temp. is easily dropped by the conduction of heat. As this result, even if firstly, the molten steel part below the molten steel surface level 9 is supplied into the mold 6, as the oxidation is not developed and the temp. drop is restrained, the float-up and the separation of the non-metallic inclusion in the molten steel at the initial stage, are promoted and the insufficient slagging of mold powder can be prevented.
