IPC: H04M1/26
Filed: 1987-06-22
Abstract: PURPOSE:To omit the manual mode switching operations by providing a means which switches automatically the pulse mode of a dial signal set in a calling state to a tone mode when a circuit is set up to the remote side. CONSTITUTION:When an operator hooks off a handset 4 from a facsimile equipment 1 and operates the ten keys for input of a telephone number of the remote side, a prescribed dial pulse is outputted from a dial pulse/tone generating circuit 23 and the remote side is called. When the remote side gives an answer to said calling, the circuit polarity is inverted. This inversion of the circuit polarity is detected by a circuit current polarity inversion detecting circuit 21. Then a prescribed signal is outputted to an MPU 27. Thus the MPU 27 switches the present mode to a tone mode so that a DTMF signal is outputted from the circuit 23. Then a pulse mode is reset when the operator sets the handset 4 again to the equipment 1.

Abstract: PURPOSE:To reduce a detection error, by deriving an offset by average-processing for an angular velocity turning round an X axis when installing an angle sensor in the X axis direction, subtracting the result from a signal by an angular velocity turning around a Z axis, and executing its integral processing. CONSTITUTION:In case when a prescribed direction on the horizontal plane and a vertical direction of a vehicle are set as an X axis and a Z axis, respectively, angular velocity sensors 12, 13 are made to move its installing direction alternately by a prescribed timing due to a time factor in the X axis direction and the Z axis direction. When installing in the X axis direction, an offset is derived by executing average-processing of an angular velocity signal from the angular velocity sensor. When installing in the Z axis direction immediately after it, an angular velocity turning around the Z axis is derived by subtracting the offset from the angular velocity signal fed from the angular velocity sensor. Subsequently, the offset is updated successively in its time by integral-processing this derived angular velocity by a microcomputer 39 so that a running bearing of the vehicle is derived.

Abstract: PURPOSE:To constrict currents excellently, and to obtain a visible-ray semiconductor light-emitting element having superior performance and reliability by forming double hetero-structure, containing (AlxGa1-x)0.5In0.5P as an active layer and (AlyGa1-y)0.5In0.5P (1>=y>x>0) as a clad layer, and shaping a second conduction type first GaAs layer and a first conduction type second GaAs layer. CONSTITUTION:A p-Ga0.5In0.5P layer 202, (w) of which is brought to 0, and an n-GaAs layer 203 are formed onto p-(Al0.55Ga0.45)0.5In0.5P 201, (y) of which is brought to 0.55, in succession as clad layers having double hetero-structure, and part of the n-GaAs layer 203 is removed to shape an opening. The surface of Ga0.5In0.5P 202 is exposed in the opening at that time and has a small Al composition, and is hardly affected by surface oxidation. Even when second growth is conducted on the surface of an (AlwGa1-w)0.5In0.5P layer, the effect of an oxide film can be ignored when w<=0.3 holds. A p-GaAs layer 204 is shaped onto the p-Ga0.5In0.5P layer 202 and the n-GaAs layer 203 by second growth, and is not grown on the surface of the high Al composition layer, thus improving crystallizability.

Filed: 1993-06-28
Abstract: PURPOSE:To reduce deterioration in picture quality by measuring a generated code quantity for each block and controlling a round-off range of picture information based on the result of measurement thereby enabling the encoding and decoding of picture data. CONSTITUTION:A DCT coefficient as a result of discrete cosine transformation at an orthogonal transformation device 3 is quantized by a quantizer 4, subject to variable length coding at a variable length encoder 5 and outputted to a storage medium of picture data. In this case, a code quantity measurement device 6 measures the code quantity of data subject to variable length coding and gives the result of measurement to a coefficient transformation section 7. The coefficient transformation section 7 compares each picture code quantity sent from the code quantity measurement device 6 with a predetermined code quantity latched in an object setting section 8. Then a coefficient transformation section 7 corrects the code quantity increasingly when the measured code quantity is lower and corrects the code quantity decreasingly when the measured code quantity is in excess.

IPC: H01L21/28
Filed: 1985-07-16
Abstract: PURPOSE:To form a buffer layer capable of effectively preventing migration in a semiconductor device by a method wherein ions are implanted into an interface, along which wiring aluminum and silicon contact each other, for the prevention of the two elements from going into reaction. CONSTITUTION:An insulating film 2 is laid on an element forming region on a silicon substrate 1 by a conventional means. A contact hole 3 is provided, whereafter an aluminum film 4 is deposited by evaporation. The thickness of the aluminum film 4 should generally be between several 1,000Angstrom  and 1mum. A resist film 5 provided with an opening for a contact hole is provided on the aluminum film 4, whereafter ions are implanted of such a high-melting metal as Ti, Mo, or W, or nitrogen. The ion accelerating voltage is so selected that ions may penetrate the aluminum film 4 and that the center of their distribution may be positioned on a contact interface 7 between the aluminum film 4 and silicon substrate 1. In the case of Ti ions, they will be driven at approximately 500KeV. Implanted high-melting metal ions combine with the silicon substrate 1, to form a high-melting metal silicide. This technique allows the contact interface 7 to have migration-preventing capability without loosing conductivity a contact interface is supposed to have.
