Filed: 1987-06-09
Abstract: PURPOSE:To avoid the influence of the ambient temperatures that is given to the arithmetic result and also to reduce the error of a power detector, by applying only the digital operations to obtain the effective electric power. CONSTITUTION:An energizing angle computing element 9 detects a time point when the input voltage A1 of an AC phase control power supply is set at zero as well as the energizing time of the output voltage A2 and calculating digitally an energizing angle based on said time point and energizing time. An average current value arithmetic unit 7 detects digitally the average value of the current flowing to a load from the output of a current transformer CT connected to a line A3 led toward the load.

A ROM of 512k bits is used to both the element 9 and the unit 11 respectively. Thus these calculations receive no influence of temperatures owing to the ROM structure and the calculation speed is satisfactorily high together with an extremely reduced calculation error.

Title: Noise controller
Inventor: TERAI KENICHI
IPC: G10K11/178
Filed: 1992-06-04
Abstract: PURPOSE:To eliminate a noise over a wide band even if a target noise source generates a signal with high chromatic property by flattening the frequency spectrum of an error detection signal by a whitening filter. CONSTITUTION:The noise from the noise source 16 which reaches an error detector 4 after passing through a transfer function G is eliminated by processing the detection signal of the noise detector through an adaptive filter 2 and generating a control sound by a control speaker 3 through a spatial transfer function C. The detection signal of the error detector 4 is passed through the white filter 5 and inputted as an error signal of a coefficient update computing element 6. The noise detection signal is passed through a front filter 7 matched with a transfer function from the control speaker 3 to the white filter 5 through the error detector 4 and inputted as a reference signal of the coefficient update computing element 6. Consequently, the coefficient is updated in consideration of the influence of the white filter 5 and the chromatic property of the error signal is removed to preclude coefficient update of only a specific frequency.

Abstract: PURPOSE:To enable to accurately match the optical axis of a light emitting diode to the mechanical axis of a lens sphere and to readily coincide therebetween by arranging electrodes of three metal layers on the periphery of a window for emitting a light of a semiconductor substrate and supporting the lens via the electrodes. CONSTITUTION:The first deposited film 6 is formed, for example, of gold. germanium/nickel (AuGa/Ni) or the like, and is an original electrode which is ohmically contacted with the surface of a light emitting diode element substrate 1. Since a gold (Au) plated layer 7 on the electrode is porous, it is difficult to bond a gold (Au) wire 9. Even if bonded, the bonding strength is not sufficient. Then, the second deposited film 8 which facilitates the bonding of the wire 9 is formed on the layer 7. This film 8 is formed by covering gold by depositing, and fine lead wirings 9 made of gold wirings can be rigidly bonded by providing the thin film. The film 8 can be further formed as rigid film by employing gold crystal alloy such as gold germanium (AuGe) by altering the film 8 with the gold (Au).
