Title: Speed controller for dc motor
Inventor: YUASA MASAHIRO
IPC: H02P6/08
Filed: 1985-11-18
Abstract: PURPOSE:To eliminate a D/A converter by outputting a reset pulse prior to a control pulse having a pulse width responsive to a speed deviation. CONSTITUTION:A speed detecting pattern 11 outputs the rotating speed of a rotor in the form of an induced voltage to inputs 12a, 12b of an amplifier 13, and input the speed through the amplifier 13 to the interrupt terminal 19 of a muCPU 18. The muCPU 18 outputs a control pulse CTL having a pulse width responsive to the positional difference between the speed signal and a reference signal, and outputs a reset pulse RST prior to the pulse CTL. A D/A converter 22 discharges a capacitor on the pulse RST, charges the capacitor on the pulse CTL to convert a digital signal to an analog signal, and applies it to a driver circuit 17.

Abstract: PURPOSE:To make it possible to detect heights quickly and to decrease detecting errors by providing a means which transduces the selected height data into acoustic frequency data. CONSTITUTION:A keyboard 24 is operated. A relationship between the height of a component and an acoustic frequency is set so that the difference between the heights of the different kinds of components is readily recognized with human auditory sense in correspondence with an object to be inspected. The surface of, e.g. a circuit- component mounted printed wiring board 10, is optically scanned with a height detector 12, and the height of the surface is detected. The value is written into a height memory 14. A height image is displayed on a display device 16. A component-height-data selecting part 20 reads height data at the regular part-mounting position of a component-mounting-position memory 18 among the surface height data in the memory 14. The data are written in a component-height memory 22. A height/frequency transducer part 26 transduces the height data into acoustic frequency data. The data are supplied into an acoustic output circuit 28 for a time t1. Then data for frequency 0 are supplied for a time t2. Therefore, the sound at the frequency corresponding to a component A (thereafter, sequentially B...) is outputted from a speaker 30 for the specified time t1. Then the output of the sound is stopped for the specified time t2.
