Abstract: PURPOSE: To obtain a semiconductor device including an active layer having low lattice mismatch rate with respect to a GaN based growth layer in which the band gap can be decreased while suppressing increase of the lattice mismatch rate. CONSTITUTION: A GaN butter layer 2, an n-GaN layer 3, an n-Al0.15 Ga0.85 N clad layer 4, a GaN1- YPY active layer 5, a p-Al0.15 Ga0.85 N clad layer 6, a p-GaN layer 7 and a p-GaN1- YPY contact layer 8 are formed sequentially on a sapphire substrate 1. The lattice mismatch rate rate of the active layer with respect to the Al0.15 Ga0.85 clad layers 4, 6 is decreased by employing GaN1- YPY as the material of active layer. Good ohmic characteristics are attained while suppressing increase of the lattice mismatch rate with respect to the p-GaN layer 7 by inserting the p-GaN1- YPY contact layer 8 between the p-GaN layer 7 and a p-side electrode 9.

Title: Method and device for detecting disconnected section of distribution line
Inventor: KUMEGAWA HIROSHI
IPC: H02H7/26
Filed: 1991-05-27
Abstract: PURPOSE:To determine a disconnected section of a distribution line without requiring a voltage sensor by measuring the current of the distribution line at a terminal station located for every predetermined section on the distribution line. CONSTITUTION:A distribution line is divided into a plurality of sections and phase currents Ia, Ib, Ic are detected at a measuring point in each section. Positive-phase current I1 and negative-phase current I2 are then calculated based on thus detected currents. When the line voltage Vij is higher than a threshold Vth, any one of the currents Ia, Ib, Ic is larger than thresholds Iax, Iby, Icz and the ratio I2/I1 exceeds a threshold k0, a decision is made that the measuring point is closer to the load side than the disconnection point thus determining the disconnected section. Consequently, disconnection fault point can be determined easily and reliably.

Abstract: PURPOSE:To correctly extract a stroke by comparing the width and the direction of a stroke with regard to each stroke passing through a superposed area and separating the stroke, based on a result of comparison. CONSTITUTION:A superposed area of a stroke of an image pattern F is detected by a detecting circuit 12, and thereafter, with regard to all the superposed areas that have been detected, the width and the direction of the stroke in the vicinity of each superposed area are extracted by an extracting circuit 13, the width and the direction of each stroke which has been extracted are compared, and based on a result of its comparison, the superposed stroke in those superposed areas is separated.

IPC: B22D11/16
Filed: 1982-07-13
Abstract: PURPOSE:To make a level of the molten metal constant and to enhance level detecting accuracy, by using a float, whose durability is maintained by a gas cooling method, and directly detecting the level of molten metal in a mold. CONSTITUTION:In casting operation, the level of molten metal in a mold is outputted as an electric signal A by a level detector 16 through a float. When the electric signal A can be transmitted, the input signal A from the level detector 16 and an input signal B from a control level setter 19 are compared and operated by a comparing operator 17. Based on the difference, a control signal C is transmitted to a control device 20. When the level of the molten metal is higher than a preset level and the constant speed casting is performed, a signal (a) is sent to a controller 22 and a sliding nozzle of a tundish is squeezed. In the operation other than this, a signal (c), which expedites the casting speed is sent to a controller 26 through a pinch roll, and the level of the molten metal is returned to the preset level.

Abstract: PURPOSE:To obviate a viewer's sense of incongruity by transmitting only a sound signal without a delay, or by an allowable small delay at the time of bringing a conversation to TV broadcast through a communication satellite. CONSTITUTION:In order to make a delay of a sound signal small, only this signal is allowed to pass through, for instance, a submarine cable. In order to send a voice in Tokyo to New York by a submarine cable, only the sound signal is demodulated by a demodulator 9 and transmitted by a telephone line 10, and on the contrary, a voice in New York is sent to Tokyo by a demodulator 11. In this case, a delay device 8 is provided in order to adjust a time relation of both the signals, and by switching this device by a switching and synthesizing device 6, the signals are sent out. In such a way, a viewer's sense of incongruity can be obviated, although there is such a little unnaturalness as a sound comes out first to conversers in both the places.
