Title: No-ringing terminal equipment
Inventor: KUWANO MASAYA
IPC: H04M11/00
Filed: 1989-10-09
Abstract: PURPOSE:To simplify the circuit constitution and to attain small size and low cost by adopting an optical signal for the detection of a signal from a trunk line and the control connecting a meter sensor from a control section to the trunk line and eliminating the need for an external power supply to the circuit connecting to the trunk line side. CONSTITUTION:When the polarity of trunk lines L1, L2 is inverted and the trunk line L1 reaches an earth level (earth) and the line L2 reaches a prescribed DC voltage (battery), a light emitting diode ED 2 to detect a bell signal is blinked corresponding to a connection control signal. A connection control signal (NRS) being an AC current superimposed on a DC current from the trunk line L1 flows to the trunk line L2 via a full wave rectifier RE 2 and a capacitor C2 through a transformer TR 5, a diode D4, a photo TR PT 4 and the full wave rectifier RE 2. Then the data communication line between the SE 1 and a no ringing trunk 14 is set and data communication is implemented between the meter sensor SE 1 and the no-ringing trunk 14 via the transformer TR 5 and a 2/4-wire conversion circuit 32.

Abstract: PURPOSE:To smoothly control a temperature of an object to be heated in a steaming period by supplying heating power for heating the object to be heated by electromagnetic induction, and reducing gradually the heating power concerned in the steaming period after the object to be heated is cooked. CONSTITUTION:Based on a temperature detecting signal of an object 5 to be heated by a thermistor 6, a heating control signal is applied to an analog switch 11 from a control part 2, and a high frequency switching element 8 is brought to ON/OFF control through a driving pulse generating circuit 10 and a circuit 9. By its element 8, a current of a power source rectified by a rectifying circuit 12, smoothed by a choke coil 13 and a capacitor 14 and given to a heating coil 15 is turned on and off. By electromagnetic induction based on an AC magnetic field of this coil 15, the object to be heated such as rise, etc., in an inner rice-cooking pot 5 is heated. In a steaming period after this object to be heated is cooked, the heating power concerned is reduced gradually. As a result, a temperature of the object to be heated in the steaming period is controlled smoothly, and the object to be heated can be heated moderately.

Abstract: PURPOSE:To shorten the time spent in measuring by forming the structure controlling the moving speed of a device main body or the body to be measured based on the output signal of a detector generated at the time when the relative position of the device main body and the body to be measured becomes a constant position relation. CONSTITUTION:The body 45 to be measured or device main body 1 are moved at high speed by the control of a control device 3 until the body to be measured comes to the position shown by a symbol 45' for the device 1.
