Title: Cylinder head gasket
Inventor: JINNO OSAMU
IPC: F02F11/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a cylinder head gasket capable of effectively preventing blow-by of combustion gas. SOLUTION: A cylinder head gasket 1 is provided with a first gasket board 2 and a second gasket board 3. A first and second inner protrusion parts 2A and 3A protruded in a reverse direction to each other are formed on the gasket boards 2 and 3, respectively. Further, radial central parts 2a and 3a protruded in a direction in which the central parts approach each other and which are peripherally continuously adhered to each other are formed at the protrusion parts 2A and 3A, respectively.  This constitution causes the first gasket board to be brought into forced contact with a cylinder head and the second gasket board to be brought into pressure contact with the cylinder block by the pressure of combustion gas about to effect blow-by of the combustion gas through a gap between the first and second gasket boards 2 and 3 to an external part through a gap between the first and second gasket boards, and brings the radial central parts 2a and 3a into pressure contact with each other by a reaction force thereto, whereby blow-by of combustion gas is effectively prevented from occurring.

Title: Injection mold
Inventor: UENO HIROSHI
IPC: B29C45/26
Filed: 1986-11-08
Abstract: PURPOSE:To make it possible to simultaneously obtain a large number of molded items and at the same time facilitate the release of the molded item from molds by a method wherein the parting line of a cavity is provided obliquely to the direction of closing between a cavity plate and a core plate and, an ejector pin is provided on the core plate. CONSTITUTION:Molding is performed by pouring molten resin from a nozzle touch 53 through a pouring path 59 in the cavity 43 of an injection mold 31. At this time, since the parting line P is provided not perpendicularly but obliquely to the direction of closing or to axis line A, a force X acts obliquely to the axis line a, resulting in allowing to make the component Y in the direction of the axis line A of the force X smaller than the force X, and consequently to make the necessary mold closing force per cavity smaller. As a result, the provision of two cavities in one pair of molds becomes possible and accordingly the molding efficiency can be enhanced. Next, when the resin in the cavity 43 solidifies, the mold is opened and an ejector pin rod 63 is ejected in order to release a molded item M from the mold.
