Title: Ignition timing control device of internal-combustion engine
Inventor: YAMAGUCHI HIROSHI
IPC: F02P5/145
Filed: 1982-07-05
Abstract: PURPOSE:To control an engine at optimum ignition timing invariably by correcting the ignition timing in accordance with the ignition timing and the crank angle position where the cylinder pressure becomes the maximum for each cylinder. CONSTITUTION:The ignition timing A' and the crank angle position thetapmax where the cylinder pressure becomes the maximum for each cylinder are read at a step 50 to judge whether or not A'+thetapmax is equal to a predetermined value D or less. If it is more than D, the ignition timing is too late, therefore the ignition timing is advanced. If it is equal to or less than D, an average value thetaM of thetapmax is calculated at steps 51, 52. When thetapmax is at a predetermined position the fuel consumption rate becomes the highest, thus a correction value alpha is determined at a step 53 so that thetaM becomes its predetermined position. Thereby, an engine can be controlled at optimum ignition timing invariably.

Title: Injection molding die
Inventor: MORIKITA NOBUO
IPC: B29C45/38
Filed: 1987-05-12
Abstract: PURPOSE:To cut a gate section of a molded product in a mold with good accuracy of shape by connecting an ultrasonic wave generating device to generate supersonic waves in the tangential direction of disc-gate-constituting component rotatable around a sprue as a center. CONSTITUTION:Resin injected is filled in a cavity 10 through a sprue 18 and a disc gate 17. After the resin is cooled down, a vibrator 14 is vibrated and amplified by a metal horn 15. Then said vibration is transmitted to an insert die 4 through a pin 16 and an arm 3 and becomes vibration in its tangential direction, and transferred to a molding sprue and disc through a whirl-stop channel 12. Then, shear stress is added to the gate section 17 by supersonic waves to break the gate section 17. Thus, the gate section of molding disc can be finished easily and neatly with good accuracy of shape in the mold.

Title: Precharging circuit
Inventor: MASUDA MASASHI
IPC: G06F3/00
Filed: 1990-05-02
Abstract: PURPOSE:To prevent the generation of a spike type transient current caused in the precharge start timing by connecting a depletion type transistor TR serving as a constant current circuit in series to a precharging enhancement type TR. CONSTITUTION:When a data bus line 4 is kept at 'L' and a precharging control signal 6 is changed to 'L' from 'H', a precharge TR 2 is turned on and the precharge of the line 4 is started. Then the potential 7 of the line 4 is changed to 'H' from 'L'. In such conditions, a constant current TR 1 controls a precharging current 8 to a constant level and suppresses a spike type transient current caused in the precharge starting timing. In this case, a depletion type is used as the TR 1 in order to charge the line 4 up to a power potential. Thus the fluctuation of the power potential caused in the precharge start timing can be minimized.
