摘要： PROBLEM TO BE SOLVED: To perform efficient cooling centering around a portion between intake and exhaust ports which there is necessity to preponderantly cool. SOLUTION: A water jacket partitioned into two layers of the one being an upper layer and the other being a lower layer is formed at a cylinder head 10. A water jacket 15 on the lower layer side has a cooling water inflow port 20 formed at each cylinder and a passage (a horizontal passage) 21 for an exclusive use classified by a cylinder is formed in a manner to run from each inflow port 20 through a gap between an exhaust port 11 and an intake port 12 and elongated in a direction extending approximately orthogonally to a cylinder row direction. A common passage (a vertical passage) 22 communicated with the downstream part of the passage 21 and elongated in the direction of a cylinder row is formed in a spot situated downstream of the horizontal passage 21. A communication port 25 to feed cooling water to a water jacket on the upper layer side is situated at one end part of the vertical passage 22.

摘要： PROBLEM TO BE SOLVED: To ensure sufficient rigidity against combustion pressure while avoiding increase in weight. SOLUTION: This cylinder head 10 includes ribs 32 reinforcing the coupling between boss portions 22, 23 for bolts into which head bolt fastening the cylinder head 10 to a cylinder block is inserted. Also, the cylinder head 10 includes ribs 30, 31 reinforcing the coupling of the boss portion 22 for bolts with a boss portion 20 to house an injector which is disposed in the upper middle of a combustion chamber 14 through boss portions 21 for a valve guide of an engine valve. The rigidity of the cylinder head 10 against combustion pressure is effectively improved by transmitting fastening force of the head bolts to the boss portions 20, 21 provided in the upper side of the combustion chamber 14 through the ribs 30 to 32.

摘要： PURPOSE: To efficiently prevent the occurrence of a shrinkage cavity by increasing the feeder head effect in local pressurizing. CONSTITUTION: In a casting method, in which molten metal is locally pressurized according to the solidified condition of the molten metal after packing the molten metal into a cavity, a pressurizing pin 9 is retracted after filling up the cavity with the molten metal and a space is formed between the thin film of solid phase (x) on the surface of molten metal and the tip surface of the pressurizing pin 9 and the fluid is sealed in this space and pressurized to locally pressurize the molten metal. By this method, only liquid phase part (z) can efficiently be pressurized almost without receiving the effect of the solid phase (x) and coexisting phase (y) of the molten metal. Further, the molten metal in the part in contact with the liquid and its neighborhood is difficult to solidify by heat insulating effect of the fluid. Therefore, the solid phase layer (x) in this part is thinned and also, the density of the solid phase in the coexisting layer (y) is reduced and the pressure of the fluid is efficiently applied to the liquid phase part.

摘要： PURPOSE:To prevent the disconnection of leads at an outlet of a case even if it is vibrated by press-fitting a bush made of an elastic material, such as rubber or resin, between the leads of a piezostack and the case. CONSTITUTION:A piezostack 1 is put in a case 2, leads 3 are extended from the holes of the case 2, and bushes 4 are then press-fitted while passing the leads. Accordingly, it is much more advantageous in both its cost and its operating efficiency than by steps using an adhesive. Since compressive stresses are applied from the bushes 4 press-fitted with the leads 3, they are effectively secured to be safe against a tension at the time of using. Further, since the bushes 4 are formed of elastic material, such as rubber or resin, the leads 3 are not disconnected at outlets of the case 2. There is no possibility of damage caused by irregular contact due to the flow of the adhesive. Even when it is attached in a fuel injection pump of a Diesel engine which is vigorously vibrated, it can maintain high reliability for a long period.

摘要： PURPOSE: To remove molding sand thoroughly from castings and supply the castings a constant posture to the next process by treating the castings cast in vertically split flaskless type molds with a sand cutting device, a suspension supporting device by clamps and a knock-out device while moving these continuously.
CONSTITUTION: A large number of continuous cast molds 1 which cast molten metal in molds of a vertically split flaskless system and are fed in a direction A by a mold feeder 2 are solidified during conveying and in this state, they are fed to the position of a sand ductting device 23. The pawls 26 of the device 23 are inserted into the top surface and upper both sides of the molds reiteratively, by which some parts 27 are cut of sand to expose shoulder parts 3. The parts 3 are supported with bars 19, and when they come to a prescribed position, air cylinders 14, 17 advance so that clamps 13, 18 apply restraining under pressure grasping to the parts 3 and the molds 1 from both sides; at the same time, the speed of the clamp 18 is made faster than that of the 13 to cut the remained molding sand completely owing to the differences in their relative speeds. In the constant posture, the castings are shifted to the next processes of ingate breaking, etc., whereby the working efficiency is improved.
