Title: Distribution line carrier system
Inventor: TERADA MAKOTO
IPC: H04B3/54
Filed: 1985-08-26
Abstract: PURPOSE:To efficiently transmit signals by bridging two phases other than a neutral phase and inserting frequency selective impedances, which by-pass single-phase loads connected in individual phases, between system lines of these two phases and balancing impedances of two phases other than the neutral phase to the neutral phase. CONSTITUTION:When a high frequency signal is applied from a transmitting and receiving circuit 31, this signal is flowed to a system line 2 through a coupling transformer 30, and the signal current is flowed in the direction of an arrow. Impedances 32a-32c balance the impedance between phases (b) and (n) and that between phases (c) and (n) to the high frequency signal current including impedance of the system line 2, a filter 5, a V connected transformer 1, and the power supply side and are operated to approximate potentials of phases (b) and (c) to the line of the phase (n) for the high frequency signal to each other. Since a great imbalance is not caused in the reception side with respect to the signal frequency though a slight imbalance is caused by a power supply frequency and the other higher harmonic generating sources, up currents to phases (b) and (c) are detected to receive the signal.

Filed: 1982-10-25
Abstract: PURPOSE:To raise the operating efficiency of a device by executing continuously an operation in case when the operation is not obstructed even if an AC power source is cut off and drops instantaneously. CONSTITUTION:When an AC power source A is cut off instantaneously, an electric power source abnormality detecting circuit 1 outputs a detecting signal C and monitoring voltage D of L informing that voltage drops temporarily to a prescribed threshold level or less. On the other hand, when a voltage side of a DC power source B is normal, a monitoring signal E of H is outputted, and when the voltage is in a threshold level or less, the signal E of L is outputted. Also, the monitoring signal E is inputted to a reset signal generating circuit 3 through a delaying circuit 4. Accordingly, when the electric power source is cut off, a reset signal G is outputted immediately, and in case when AC voltage is cut off instantaneously or drops temporarily, when the DC power source is decided to be normal, the reset signal G is not generated.

Filed: 1983-10-07
Abstract: PURPOSE:To realize application of titled mechanism even when even when frame or shape is changed by detecting location of lands of lead frame, calculating positional displacement between such detected location and center position and correcting the position of lead frame. CONSTITUTION:A position detection circuit 40 detects that the center of land of lead frame lies in which photodiode and then inputs such data to a comparison/ operation circuit 41. The information of photodiode at the center position is stored in the memory circuit 42 and this information is input to the circuit 41 for each output from the circuit 40. The circuit 41 compares and calculates both inputs and inputs a difference information, namely position displacement of pertinent land is to the motor drive circuit 43. The circuit 43 shifts the lead frame as much as such positional difference for correction and also shifts the lead frame up to the bonding position.

Abstract: PROBLEM TO BE SOLVED: To form a silicide film, while nitriding of a titanium film, is inhibited by a method, wherein a first heat treatment is performed in an atmosphere not containing nitrogen and one part of a high-melting point metal film is silicified. SOLUTION: A first heat treatment is performed, and a monosilicide film 108 is formed. As the atmosphere for the heat treatment, an argon-containing atmosphere or a vacuum atmosphere is preferable. It is necessary to set the temperature of the heat treatment in such a way that diffusion of silicon (Hereafter, the diffusion is referred to as overgrowth.) in an oxide film is inhibited, and it is preferable that the temperature be set at 500 deg.C or higher and 600 deg.C or lower. In the case where the temperature is 500 deg.C or lower, the formation of a silicide film is difficult. Moreover, in the case where the temperature is 600 deg.C or higher, a self-alignment silicide film cannot be formed due to the generation of the overgrowth. In this way, by performing the first heat treatment in an atmosphere not containing nitrogen, nitriding of a titanium film can be made to inhibit.
