Title: Combustion chamber in direct injection diesel engine
Inventor: KOTO FUMIYA
IPC: F02B3/06
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To form a combustion chamber in which both of upward and downward spray are easy to be diffused and are difficult to be mixed, to improve fuel consumption and to reduce generated black smoke by forming a step of a difference in level shape between a side wall of the combustion chamber that upward spray reaches and a bottom surface of the combustion chamber that downward spray reaches. SOLUTION: In a combustion chamber 3, upward spray 6 injected from an upper nozzle hole 1a is diffused along a side wall 3a after upward spray 6 collides against the side wall 3a, and downward spray injected from a lower nozzle hole 1b is diffused along a bottom surface 3b after downward spray 7 collides against the bottom surface 3b. Upward spray 6 is diffused in space within the combustion chamber 3 by changing a diffusing direction in a step 5 of a difference in level and also downward spray 7 is diffused in space within the combustion chamber 3 in the same way. As a result, overlapping of both of sprays 6, 7 each other is prevented and a diffusion state is improved. A projection part 4 is formed at the center part of the bottom surface 3b and also overlapping of downward spray 7 each other diffused to the inside of the bottom surface 3b is prevented.

Title: Exhaust timing control device for 2-cycle v-type engine
Inventor: SUZUKI AKITAKA
IPC: F01L1/38
Filed: 1990-11-13
Abstract: PURPOSE:To interlock both exhaust valves, one of which is an air cylinder exhaust valve located at one side of a V-bank and the other of which is an air cylinder exhaust valve located at the other side thereof, with very simple structure, by connecting these two valves to each other by a bar-like member bent toward a crankshaft. CONSTITUTION:In a 2-cycle V-type engine 7, cylinder bodies 9, 10 are disposed in a crank case 8 in such a manner as to permit axes of the air cylinders to take the form of 'V' and permit these axes to be spaced apart from each other in a direction of a crank shaft. And by exhaust valves disposed in exhaust passages of the air cylinders, top edge positions of exhaust ports are substantially varied. Then, a pulley 26 is mounted on one end of the exhaust valve of the air cylinder on one side of the V bank, and a drive pulley 29 is connected to this pulley. And this exhaust valve is connected, by a connection link bent toward the crank shaft, to an exhaust valve of the air cylinder on the other side of the V bank. This enables the amount of offset of each air cylinder as measured in the direction of the crank shaft to be absorbed and enables both the exhaust valves to be interlocked with each other with very simple structure.

Title: Method of crystallizing of semiconductor film
Inventor: ONAKA EIICHI
IPC: H01L29/786
Filed: 1992-10-23
Abstract: PURPOSE:To enlarge the grain size of a polysilicon film. CONSTITUTION:An amorphous silicon film 13 is crystallized and made a polysilicon film 16 by providing a buffer insulating film 14 consisting of silicon oxide and a laser reflecting film consisting of chromium, in stripe shape or in mosaic shape, on the topside of an amorphous silicon film 13, and applying excimer laser. In this case, the laser reflecting film 15 reflects an excimer laser, so the amorphous silicon film 13 in the section where the temperature of a laser reflecting film 15 does not exist within the application range of an excimer laser becomes high, but the temperature of the amorphous silicon film 13 in the section where the laser reflecting film 15 exists becomes low. As a result, the growth speed of crystals from the nuclei of crystals existing in high- temperature range becomes larger than the growth speed of the crystals from the nuclei of crystals existing in the low temperature range, and the crystal grains having grown from the high-temperature range widens to the low- temperature range, and the grain size becomes large.
