Title: Fuel injection device
Inventor: INOUE AKIRA
IPC: F02B3/06
Filed: 1987-03-02
Abstract: PURPOSE:To enable the diesel engine to properly run particularly at its low- speed running by controlling an optimal injection timing detecting the time at which cylinder's inside pressure reaches a peak. CONSTITUTION:The time at which the pressure in a cylinder 2 of the engine reaches a peak is detected by a cylinder's inside pressure sensor 13 corresponding to an angle of rotation of a crankshaft 5 detected by a crank angle sensor 11. Based on the detected signal a central control unit 10 calculates an actual main injection timing, compares the actual main injection timing with an optimal main injection timing, and feedback-controls the optimal main injection timing so as to eliminate the difference between both the injection timings. When a pilot injection end timing and a pilot injection quantity can be specified based on the main injection, a pilot injection beginning timing can be calculated. So the beginning timing of the optimal main injection and pilot injection are calculated, and are stored in the central control unit 10 as the reference values of the optimal injection timing.

Title: Grinder
Inventor: KAWAGUCHI KEIJI
IPC: B24B49/16
Filed: 1986-03-04
Abstract: PURPOSE:To attain a stable gap action, by comparing a value detected by an electric power detector, with an electric power reference value set by a contact detection level setting unit, to generate a contact signal when the detected value has reached the electric power reference value, and by modifying the electric power reference value depending on the diameter of a grindstone. CONSTITUTION:Electric power P1 consumed as a grindstone shaft drive motor is in action is found out by an electric power detector 21 connected to the motor. No-load electric power P10 consumed by the grindstone shaft drive motor and dependent on the diameter of a grindstone is stored in a no-load electric power memory 22 at the time of beginning of cutting-in. After the beginning of cutting-in, the stored no-load electric power P10 is subtracted from the consumed electric power P1 by a calculator 23 so that net consumed electric power P0 is detected. Electric power PD corresponding to the diameter of the grindstone is determined by a level modifier 25 from a grindstone diameter signal and electric power which is set by a contact detection level setting unit 24 and which is consumed when the grindstone is in contact with the inside surface of a workpiece. When the net consumed electric power P0 is larger than the electric power PD, a workpiece contact signal is generated by a comparator 26.
