Title: Combustion chamber of engine
Inventor: TAKAMORI YUUJI
IPC: F02B23/00
Filed: 1982-09-08
Abstract: PURPOSE:To enhance a dead volume reducing effect without lowering charging efficiency and contrive to improve output and fuel consumption, by a method wherein a coated layer of a heat-resistant synthetic resin containing a soft metal and having appropriate pores is provided by flame spraying in a predetermined region of either one of a top surface of a piston and a wall surface of a cylinder head. CONSTITUTION:A porous coated layer 13 having elastic deformability is provided by flame spraying on the top surface of the piston 3 constituting an outside edge part of a small gap part 6a of the combustion chamber 6. Therefore, even when the gap between the top surface of the piston 3 and the wall surface of the cylinder head 4 is reduced due to thermal expansion at the time of starting an operation after assemblying the engine or in a normal operating condition, the top surface and the wall surface are prevented from making direct metal contact with each other when the engine 3 comes to the top dead center, and only the coated layer 13 provided at the small gap part 6a collides against the wall surface of the cylinder head 4, and comes into close contact with the wall surface while being deformed into the shape of the wall surface. Accordingly, since the gap at the outside edge part of the small gap part 6a becomes extremely small, substantially zero, dead volume in the combustion chamber 6 can be securely reduced, and combustion property can be enhanced.

Title: Vibration compaction sand pile forming equipment giving no vibration damage
Inventor: NAGASAKI KOICHI
IPC: E02D3/10
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To create sand piles having the quality equal to or better than the conventional ones in a shorter period of time and at a low cost by restricting the influence of vibrations to nearby houses without decreasing vibration energy of a vibrohammer used during sand pile formation. SOLUTION: A sand pipe creating hollow pipe 1 is split vertically at the center into two pieces, and both of them are jointed with a flexible material 2 such as rubber and assembled to the previous hollow pipe 1. Vibrohammers 3a, 3b having the same output are installed to the head of respective half-divided pipe body potion; when one vibrohammer 3a is generating vibration downward, other vibrohammer 3b generates the vibration upward by mechanical or electrical synchronization. In this way, nearby ground receives vibrations reversely upward and downward at the same time, so that the vibration waves having different phases are interfered and canceled each other so that damages by the vibrations to the nearby area can be eliminated.

Title: Automatic paper feeding device
Inventor: MORITA SEIICHI
IPC: B65H1/12
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To ideally feed documents undesirable if large load is applied to paper by pushing a bottom plate upward by cam mechanism, and taking out the documents, disposed near the lower part of a vertical plate and stored vertically between the vertical plate and a pressing plate, downward sheet by sheet from the vertical plate side by a takeout roller. SOLUTION: At the time of charging documents 56, a pressing plate 44 is moved to the right, that is, in the direction of going away from a vertical plate 34, and the documents are put vertically between the pressing plate 44 and the vertical plate 34. Since the pressing plate 44 is pulled toward the vertical plate 34 by a spring 48, the documents 56 are vertically held between the pressing plate 44 and the vertical plate 34. Cam mechanism 52 pushes up a bottom plate 36 and keeps the bottom plate 36 in a slightly inclined state. At this time, the pressing plate 44 is inclined to the right in relation to a vertical state, but the pressing plate 44 presses the documents 45 to the vertical plate 34, so that the vertical plate 34 becomes almost parallel with the pressing plate 44.  When a takeoff motor 12 is rotated in this state, the document 56 in contact with the vertical plate 34 is taken out downward being held between a takeoff roller 38 and a small diameter roller 42 and led to a document intake 18.

Title: Atomizer
Inventor: NAKAMURA KUNIO
IPC: B05B7/00
Filed: 1977-12-27
Abstract: PURPOSE: To provide efficient spraying of liquid with a simple device without any special components such as a sprayer and swirler, by utilizing effectively various kinds of aerodynamic forces of a turbo fan.  
     CONSTITUTION: When an impeller 23 is driven to the arrow a direction by means of a motor 22 fitted in a turbo fan casing 21, air through a suction port 28 is blown toward a discharge port 30. As liquid fuel is dripped through a feed pipe 31 on the impeller 23 swirling, the centrifugal force blows away the fuel. Coarse oil drops collide with an annular partition wall 26 fitted to the impeller 23 and destroy themselves to become nearly even oil particles and go through a passage fitted to the partition wall 26. The fuel thus atomized is mixed with air in an impeller passage 25 and casing passage 29 and is discharged from the discharge port 30 as combustible gas.
