Title: Drive method for stepping motor
Inventor: KIMURA MAKOTO
IPC: H02P8/18
Filed: 1995-02-09
Abstract: PURPOSE: To suppress hammering at the time of initialization by subjecting the rotor to microstep drive at the time of initialization for returning the step angle back to the initial position and setting the step drive frequency lower than a normal value. CONSTITUTION: At the time of initialization for returning the step angle of the rotor of a stepping motor 3 to the initial position, the step drive frequency is set lower than a normal value thus lowering the rotary angular speed of the rotor. Furthermore, a PWM control circuit divides the step drive signal at each step by four in the direction of the time base. The drive signal is then subjected to PWM control at each divided step and delivered to each stepping motor drive circuit under a state where the ON duty ratio of the drive signal is increase or decreased stepwise at each divided step. With such arrangement, the rotor of a stepping motor 3 can be held at a pitch of 1/4.

Abstract: PURPOSE:To enable an internal combustion engine to be operated within a range in which a driving power transmission system can endure, by equipping the engine with a torque suppressing means which decreases a rotary output so that a torque value, detected by a torque detecting means, is kept equal to a predetermined value or less. CONSTITUTION:In an electronic control circuit 20, the present rotary output of an internal combustion engine 1 about a transmission 22 serving as the center is estimated for what amount of torque is applied to a driving power transmission system which transmits the rotary output to driven wheels serving as the load. Thereupon, from output signals of a shift position sensor 24, rotary angle sensor 18 and an intake pressure sensor 15, a decision is performed for a shift position to be placed in the first speed further for whether or not an engine speed is within a predetermined speed region and for whether or not an intake pressure is in a predetermined value or more. And executing a delay side correction process of ignition timing only when the engine is placed in a condition that the above three conditions are satisfied, the internal combustion engine, reducing a referred value from an ignition timing table previously stored in memory for inducing the maximum output of the engine, calculates an advance timing value intentionally generating an output decrease.

Abstract: PURPOSE:To achieve correct landing work and the like by comparing the command thrust and direction to ship maneuvering elements calculated by time function on the basis of the inputted displacement quantity and load factor with the acceleration and the operated value of displacement and correcting them in case there is deflection. CONSTITUTION:In a control device 3, the displacement quantity of a marine vessel from its present point is inputted from an integrating type input device 1, the load factors of ship maneuvering elements are inputted from a setting device 2, and the most incapable load factors of the ship maneuvering elements operated corresponding to the displacement quantity are set.

Title: High-speed ecl input buffer for verticle fuse array
Inventor: UIRIAMU KENESU UOORAA
IPC: G11C17/16
Filed: 1990-02-02
Abstract: PURPOSE: To minimize the current consumption of an input buffer by pulling- down a row line so as to make the full quantity of a current absorbed into the input buffer from the row line unnecessary to pass through a current source. CONSTITUTION: When current flows through a transistor 613, the base of a pull-down transistor 641 is pulled to a low state and, when the base is pulled to the low state, the transistor 641 is turned on and, at the same time, pulls down a row line 15 by absorbing the current from the line 615. In this case, a pull-down current source 612 only absorbs a relatively small quantity of current, namely, the base current of the transistor 641. Therefore, the magnitude of the current which must be absorbed by the current source 612 is remarkably smaller than a desired quantity of pull-down current from the line 615. Accordingly, such a circuit that is suitable for driving a fuse array using a vertical fuse and is reduced in power consumption can be obtained.
