Title: Two-cycle engine
Inventor: MAEDA MASAKI
IPC: F02B25/20
Filed: 1985-09-05
Abstract: PURPOSE:To reduce the blow-bye of fresh air, without preventing an outflow of exhaust gas, by forming an exhaust route which extends from an exhaust port formed on the inner circumferential wall of a cylinder, diagonally downward, as the center line of this exhaust route bends, and the upper surface of the circumferential wall of this exhaust route slants along said center line. CONSTITUTION:An exhaust port 12 and others are opened on one-side surface of the inner circumferential wall of a cylinder of a cylinder head 6, and this exhaust port 12 leads to the outside through an exhaust route 14 which is extensionally formed diagonally downward. In this case, the exhaust route 14 is formed as its center line 20 bends gradually. That is, in the same way as the center line 20 of the exhaust port 12 side, slants in the axial direction of the cylinder, against the center line 20 on the lower stream side from the bending section A, the center line 20 is bent in the shape of 'chevron' at the bending section A following to the exhaust port 12. The upper surface 14a of the circumferential wall of the exhaust route 14, near the exhaust port 12, is also slanted along said center line 20, in the axial direction of the cylinder. That is, the upper surface 14a of the exhaust route 14 is gradually curved out, inwardly.

Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To extrude an extruded material having stable and appropriate size and shape in the longitudinal direction by forming an air layer for heat insulation between a die and a die ring. SOLUTION: This extrusion tool 1, is supported by a die slide 11 of an extrusion machine together with a bolster 9 and a dummy bolster, and at the time of executing the extrusion, the die ring 3 is gradually cooled during extruding, and it is restrained to conduct the heat held in the outer peripheral part side of the die 2 in the radial line direction to the die ring 3 side by the air layer 6 for heat insulation between the die 2 and the die ring 3. Therefore, the die 2 is held at almost the fixed stable temp. in the radial line direction during extruding to produce the extruded material E having stable and appropriate size and shape in the longitudinal direction.  Further, since grooves 7 forming the heat insulating air layer 6 are formed in the inner peripheral surface of the die ring 3 having general applicability, the number of the extrusion tool constitutional members can be reduced.

Filed: 1987-08-06
Abstract: PURPOSE:To suppress the complex scale and processing of a hardware or the increasing of a processing time by using a coefficient counted at the time a block before one frame is encoded for the normalizing coefficient of a part to execute a vector-quantizing. CONSTITUTION:For the normalizing coefficient to be used when the vector- quantizing is executed in a vector and scaler mixing quantizing circuit 107, a value, which is computed at the time point of an encoding processing before one frame and stored in a normalizing coefficient computing circuit 106, is used. Further, simultaneously with executing this vector-quantizing, only concerning a significant dynamic area, the normalizing coefficient is computed in this circuit 106 as for the present frame. Thus, the complex scale and processing of the hardware or the processing time is reduced as much as possible and moreover, the vector-quantizing whose quantizing error is small can be applied to a moving picture encoding by a code book to have generality.
