摘要： A method of controlling the drive force to be applied to the load that is driven with a servo motor, wherein the control error that is caused by the change in the condition of a transmission mechanism interposed between the servo motor and the load is decreased. A detected value (PH) of the drive force actually applied to the load is compared with a set value (PL') to be applied to the load, and a drive current of the servo motor is controlled depending upon the result of comparison. When the condition of the transmission mechanism is changed, therefore, a change in the relationship between the servo motor output and the drive force actually applied to the load is automatically compensated, so that the drive force to be applied to the load is properly controlled to assume a set value.

摘要： A transistor amplifier circuit provided with an oscillation preventing countermeasure. When a transistor (TR,) having a relatively high input capacitance is driven by another driving transistor (TR 2 ), an oscillation preventing diode (D, and/or 50) is connected to the connecting wire of both the transistors (TR,, TR 2 ). Current communication necessary between the capacitance between the collector and the base of the transistor (TR,) and the inductance due to the length of the wire can be prevented by the rectifying action of the oscillation preventing diode (D,, 50), thereby preventing oscillation of the transistor amplifier circuit.

摘要： A digital pulse circuit in which the state is inverted each after the change of a predetermined value of the quantity to be measured with N as an even number of greater than 4, and in which N digital signals are input in parallel and have phases that are different each by about 1/N of said predetermined quantity, so that the difference in phase among said N digital signals will be greater than a predetermined phase difference, to enable only two digital signals that may rise or break with the change in the quantity to be measured to eliminate the effect of noise superposed on these signals, such that the N digital signals are brought into synchronism with one another (Fig. 10) by clock pulse having a predetermined period. Or, the N digital signals are brought into synchronism with one another by clock pulses having a predetermined period, and are brought into synchronism with one another once again using the above clock pulses before they are issued. From among the signals that are once brought into synchronism with one another, only two signals that may rise or break with the change in the quantity to be measured are enabled. When these two signals change simultaneously, a logic circuit holding the output is provided so that the two signals will not be brought into synchronism in the second time until one of these signals returns to the initial state (Fig. 14). The circuit is very useful for processing the output signals of the light-receiving division of a high-resolution pulse encoder.

摘要： An operation transistor (3) is connected in series with a light-receiving element (1) and a plurality of signal-producing transistors (5a, 5b) are connected in parallel with the operation transistor (3) in a current mirror fashion. Output signals (O1, O2) resulting from photoelectric conversion supplied in parallel to a plurality of circuits are independently supplied through said plurality of signal-producing transistors (5a, 5b), in order to eliminate interference among a plurality of circuits that are served with the output signals (O1, O2) resulting from photoelectric conversion in parallel and that perform predetermined processings. Thus the signals are correctly processed to reduce the consumption of electric power. Furthermore, the response speed is enhanced.

摘要： A pulse encoder having a movement detecting unit (1) that detects the movement of an object whose position is to be detected and produces a signal having data related to the movement, and a clock generator (3) that produces clock pulses. The data related to the movement is processed while maintaining synchronism with the clock pulses. Provision is further made of an abnormal clock detecting unit (4) which inputs clock pulses as well as portions having data that indicates the presence or absence of movement of the object whose position should at least be detected among the signals having data related to the movement. When the movement is detected relying upon portions having data that indicates the presence or absence of movement despite the interruption of the clock pulse, the abnormal clock detecting unit (4) produces an abnormal clock signal.

摘要： Legs are protruded from four corners of an oblong metal plate, and screw holes are formed near the center of the metal plate such that screws can be inserted therethrough to be screwed into terminals of a threaded terminal-type electronic component, thereby forming terminals for connection to electronic components. The legs of the terminals are inserted into small holes formed in a printed board, soldered to an electric circuit, and thus secured to the printed board. Screws are inserted into the screw holes of the terminals so as to be screwed into the terminals of the threaded terminal-type electronic components. The screws are then tightened to fasten the electronic components to printed board.
