IPC: H04M9/00
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To widen the width of a voltage change in a line voltage detection port by allowing a voltage change in the line voltage detection port to be increased more than a threshold voltage when an electric lock switch is closed after a call button is depressed and a hook switch is closed through the confirmation of the operation of the electric lock switch.

A current flowing to a low current circuit 2 when an electric lock switch SW3 is closed is set so that a voltage of a line voltage detection port P1 is 6.67V. When the electric lock switch SW3 is closed after the CPU 1a is controlled and a hook switch SW1 is closed, a voltage change in the line voltage detection port P1 is 3.00V and it is higher than a voltage threshold level of 2.5V and the operation of the electric lock switch SW3 is confirmed. Thus, the width in the voltage change in the line voltage detection port is widened.

Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a phase detector, capable of obtaining a synchronizing signal similar to one obtained in a balanced state, and capable of suppressing generation of higher harmonics when an unbalanced state occurs. SOLUTION: A controller is constituted of a filter circuit 9 for extracting only the fundamental components, a positive-phase detection circuit 10 which receives the output of the filter circuit 9 as an input and detects its positive- phase component, a phase computing element 11 which receives the output of the positive-phase detector 10 as an input and computes its phase, and a phase synchronizing circuit 12, which receives the output of the phase computing element 11 as an input and causes the phase to synchronize with this input automatically. Since an unbalanced component incapable being removed by a filter is removed, by extracting only the positive-phase components, it also becomes possible to obtain even at an unbalanced time, a synchronizing signal similar to one obtained at a balanced time, and to suppress the generation of higher harmonics.

Abstract: PURPOSE:To form an undoped GaAs crystal whose residual donor impurity concentration is small and whose purity is high by a method wherein the concentration of S in a raw material of Ga is reduced in a vapor growth operation of a GaAs crystal. CONSTITUTION:A raw material of Ga 13 which has been housed in a source boat 14 installed inside a quartz reaction tube 11 is heated by using an electric furnace; a mixed gas of AsCl3 and H2 is made to flow from a gas inflow port 12. As which has been produced by heating and decomposing the AsCl3 is absorbed by the raw material of Ga 13 and becomes a saturated state. Then, a GaAs film is formed on the surface of the Ga; S contained in the Ga is segregated in the film. Then, when a mixed gas of HCl and H2 is made to flow, the S is removed together with the GaAs film and the raw material of Ga whose concentration of the S has been reduced is obtained. After that, the mixed has of AsCl3 and H2 is made to flow again; a GaAs film is formed on the surface of the Ga; a GaAs substrate 16 is set on a substrate holder 17 and a GaAs growth operation is executed. Thereby, an undoped GaAs crystal whose residual donor impurity concentration is low and whose purity is high can be obtained.

Abstract: PURPOSE:To actually confirm the difference between the present position of a target and an aiming point by confirming the difference between the present position of the target determined by aiming, that is, the aiming point thereof and the actual present position of the target by detecting laser irradiation and reflected laser beam. CONSTITUTION:An aiming part 12 allows its own aiming point to coincide with a target present position 8 to determine the target present position 8 and outputs a trigger signal 10 being a shooting command. An aiming point and a target position are set so as to coincide with the control data of a control part 13 through a control signal 2. A laser irradiation part 14 inputs the trigger signal 10 to emit irradiation laser beam 5 to the target present on an aiming line at this time. A laser detection part 15 detects the reflected laser beam 6 on and after the input of the trigger signal 10 to measure the time lag and intensity thereof to output a hit judging result 7. When the aiming due to pilot operation is improper, the target is not present on the aiming line 4 and, therefore, the irradiation laser beam 5 does not impinge against the target and is not reflected therefrom and the hit judging result 7 is outputted as 'miss'.
