Filed: 1992-07-01
Abstract: PURPOSE: To prevent a rotation deviation of an internal combustion engine over the whole engine driving extent by detecting an angular acceleration of each combustion process, comparing the respectively measured data to one another and changing a fuel injection quantity until the deviation is compensated in the case where the deviation exists in the measured data. CONSTITUTION: An internal combustion engine 1 has, for example, 4 cylinders 3. Fuel injection to the cylinder 3 is controlled through the control line 5 connected to a controller 7. The controller 7 processes a signal of a sensor 9 and the signal of the sensor 9 is provided on the controller 7 through a line 11. Particularly, measured angular accelerations of each cylinder 3 are detected and are compared to one another.

Title: Feed roll for drying veneer and drying device thereof
Inventor: TAKEDA MASAYOSHI
IPC: F26B13/04
Filed: 1995-06-15
Abstract: PURPOSE: To make it possible to dry a veneer throughout in the direction of width by forming a plurality of large diameter portions, with which the surface and/or underside of a veneer is to be brought into contact, and small diameter portions, through which hot air is passed, on the circumference of feed rolls in the axial direction at any interval, and thereby making the circumference uneven. CONSTITUTION: Sets of an upper feed roll 10 and a lower feed roll 10 are placed in the direction of transport at any interval as required to form a transport path. At this time gaps are formed between the surface and/or underside of a veneer 1 transported and small diameter portions 22, placed between large diameter portions 21, of the rolls. When such uneven rolls 10 are used both for upper roll and for lower roll, for example, a plurality of gaps are formed in the axial direction due to the small diameter portions 22 both on the front side and on the back side of a veneer 1. The gaps form a path of hot air circulation in the transport path. When a veneer is transported, therefore, hot air from an upper hot air path is directly applied to both sides of the veneer. This makes it possible to dry the veneer throughout in the direction of width.

Filed: 1985-08-09
Abstract: PURPOSE:To perform the electric resistance welding of various stocks for can starting with a tin free steel by irradiating a laser beam on the surface of the overlapping part of the welding zone in advance prior to the welding. CONSTITUTION:The welding is performed by irradiating a laser beam in advance on the whole part or one part of a steel sheet-steel sheet contact faces, 6, 7 and steel sheet-welding electrode contact faces 5, 8 in case of the electric resistance welding of the can stock like the tin-free steel coating with an extremely thin chrome plating on the steel sheet surface.
