Title: Control device for internal combustion engine
Inventor: FUKUMA TAKAO
IPC: F02D41/04
Filed: 1990-01-31
Abstract: PURPOSE:To attain the satisfactory engine acceleration performance near the opening/closing switching rotating speed of an intake control valve without deteriorating fuel consumption by lowering the set value of an engine load as the engine rotating speed nears a preset limit value in the rotating speed area at the preset limit value or below. CONSTITUTION:A setting means C outputs the set value of an engine load in response to the rotating speed when the engine rotating speed detected by a rotating speed detecting means B is a preset limit value or below. This set value is decreased as the engine rotating speed is increased. A switching signal generating means D compares the engine load detected by a load detecting means A with the engine load set value set by the setting means C and compares the engine rotating speed detected by the rotating speed detecting means B with the preset limit value of the engine rotating speed respectively, if the engine load is the set value or above or the engine rotating speed is the preset limit value or above, an intake control valve opening signal is generated, and otherwise an intake control valve opening signal is generated.

Abstract: PURPOSE:To increase efficiency and reliability of the correction of swell of a flat coil in the width direction, by pressing the flat coil from the width direction immediately after the completion of a winding process by means of a pair of correction jigs arranged on a handle part, and correcting swells generated in the winding process. CONSTITUTION:A surface 7 on the front side of a correction jig 6 is a correction surface pressing a coil 5, and a surface 8 on the back is a stopper surface abutting against a positioning surface 11 formed on both sides of a formation jig 1. A distance K between the correction surface 7 and the stopper surface 8 is set in a manner in which the width dimension W of a flat coil 5 is automatically determined. Steel material is ordinarily used for this structure, but only the surface abutting against the flat coil 5 is coated with fluorine plastic and the like, for example. After manual positioning of this constitution, a driving cylinder 15 is operated, the correction jig 6 is driven in the direction of an arrow D, and the flat coil 5 is pressed from the width direction. This operation is continued till the stopper surface 8 abuts against the positioning surface 11 of the formation jig 1. In such a manner, the swell DELTA in the winding process is corrected, and the dimension W in the width direction is assured.

Title: Image forming device
Inventor: SAKAKIBARA KENJI
IPC: G03D13/00
Filed: 1989-01-30
Abstract: PURPOSE:To shorten the length of time when only a capsule sheet is pressure- developed and to prevent a pressure developing unit from being excessively soiled by re-driving a paper feeding means so as to send a developing sheet again when the pressurizing members of the pressure developing means are brought into a closed state from an open state. CONSTITUTION:The pressurizing members 13a and 13b are closed, and the developing sheet 16 is drawn by the members and is sent while being superimposed with a microcapsule 11; at the same time, the developing sheet 16 itself is pushed by re-driving the paper feeding means 19c and 19d therefore the developing sheet 16 is securely fed. Consequently, such a trouble that the microcapsule sheet 11 itself is crushed and the pressurizing members 13a and 13b are soiled, is avoided. Even if the pressure developing is started with only the capsule sheet 11 because of shortage of initial feeding amount, the sheet is carried again toward the pressure developing unit 13 after a pressure developing operation starts, and thus, the length of time that only the capsule sheet 11 is pressure-developed can be shortened, and the pressurizing members are prevented from being excessively soiled.
