Title: Optical transmission equipment
Inventor: OKUDA MASAHIRO
IPC: B82Y20/00
Filed: 1991-10-28
Abstract: PURPOSE:To obtain an optical transmission equipment characterized by low power consumption and rapid responseness. CONSTITUTION:Light emitting elements 1, 2 respectively having band structure have high potential barriers on their collector sides and change a light emitting variable to be naturally emitted from a quantized well by controlling an electric field to be impressed to the well. When a pulse is inputted to the common collector electrode 3 of the elements 1, 2, the electric field impressed to the well is switched from high to low or low to high in both the elements 1, 2 and a change with the lapse of time in the intensity of emitted light is expressed by a rate equation. Thereby the element 1 generates a differential optical pulse at the leading edge of the input pulse and the element 2 generates a differential optical pulse at the training edge of the input pulse because the polarity of the element 2 is reversed from that of the element 1. Optical outputs from the elements 1, 2 are respectively received by two photodiodes 8, 9 and an original input waveform is reproduced by a capacitor 10 or the like.

Title: Brushless motor
Inventor: FUJISAWA MASAJI
IPC: H02P6/21
Filed: 1989-11-28
Abstract: PURPOSE:To make a window comparator unnecessary by converting counter electromotive force signals from drive windings into rectangular waved signals by means of a comparator, then by converting the rectangular waved signals into triangular waved signals by means of an integrating circuit, and by commutating the triangular waved signals to the drive windings. CONSTITUTION:Counter electromotive force detection signals obtained from drive windings 1-1 to 3 are compared with each other at the middle point by comparator circuits 20 and 21 so as to be converted into rectangular waved signals. These rectangular waved signals are converted into triangular waved voltage signals having an almost constant phase difference relative to the rotational position of a field rotor by an integrating circuit 22. These triangular waved voltage signals are used to perform the commutation of a driving current to a plurality of the drive windings. These constitutions make a window comparator unnecessary and enable manufacturing a stable, compact and low cost apparatus without any change of properties due to temperature and atmosphere. Also, the rotational position of the field rotor can accurately be detected and quickly be detected by the counter electromotive force detection signals.
