A metal gasket for providing a seal between a cylinder head and a cylinder block of an engine is a laminate of a first metal plate, a second metal plate, and a third metal plate. The first metal plate has a folded portion for positioning around a cylinder bore, the second metal plate has a first full bead inside the folded portion to provide a primary sealing portion, and the third metal plate has a second full bead provided around an outer circumference of the first full bead to provide a secondary sealing portion. The primary sealing portion has a primary sealing surface pressure, and the secondary sealing portion has a secondary sealing surface pressure less than the primary sealing surface pressure. The secondary sealing portion provides enhanced following capability during engine operation.

A metal gasket for an internal combustion engine is formed of a main gasket portion extending substantially throughout an entire area to be sealed. The main gasket portion is formed of at least one metal plate and has at least one hole to be sealed. A bore ring is disposed inside the at least one hole of the main gasket portion. The bore ring has a top portion and a bottom portion longer than the top portion to provide rigidity of the bore ring. The gasket can be properly fitted with the engine parts while protecting a bead formed on the metal plate to securely seal around the hole.

The present invention is a method for producing refreshable frozen foods, such as meat and other food. The method is suitable for freezing foods by dipping foods in an agitating jet flow of a liquid anti-freezing medium, such as ethyl alcohol, under a temperature which is controlled between -30.degree. C. and -50.degree. C. so as to have refreshable foods which may be restored to an original fresh raw state by defrosting. In the method a super rapid freezer thereof.

An electrical connector comprises a housing having a first groove for receiving a heat seal film therein and a second groove for receiving therein a printed wiring board. A spring contact is supported by the housing for electrically connecting an electrode on the film received in the first groove and an electrode on the substrate received in the second groove. The first groove is preferably formed to have a wider opening at its entrance to permit the heat seal film to be wedged into engagement with the spring contact in the first groove. An actuator is slidably supported in the housing for bringing the spring contact into contact with the electrode on the substrate and for holding the substrate in the housing.

A steel laminate type cylinder head gasket is installed in an engine with an auxiliary combustion chamber. The gasket comprises a first plate and at least one second plate situated adjacent to the first plate. The first plate is provided with at least one curved first bead situated adjacent to and at a predetermined distance away from a curved outer line corresponding to a part of a contour of a mouth plate situated above the gasket, a second bead situated adjacent to and at a predetermined distance away from an inner line corresponding to a part of a contour of a cylinder bore, and a plurality of third beads disposed at a predetermined distance away from each other. The second bead intercrosses the first bead. The third beads are arranged so that the third beads are in order situated away from the inner line and intercept the first bead.
