Abstract: PROBLEM TO BE SOLVED: To promote the downsizing and the reduction of operation labor by supplying load selectively with the power from the first power source part including a capacitor for power storage which is charged with the DC power converted from the power from the AC generator for generating electricity with a manual rotating mechanism, and the second power source part including a primary battery. SOLUTION: The three-phase AC voltage that a three-phase AC generator 11 generates by the rotation of the handle for rotation of a manual rotator 12 and the current are rectified with a group 420 of rectifying elements, and they are supplied to the electric double-layer capacitor 51 of a capacitor for power storage of the power source part to supply specified DC power so as to charge it. A switch 50 has a mobile contact 500 to be selectively connected to the contact 50A connected to the capacitor 51, the contact 50B connected to the primary battery 52 of the power source part, or a vacant contact 50C. A radio receiver constituent part 56 operates with the DC voltage and current of the capacitor 51 or the primary battery 52 as an operation power source, consequently it reduces the rotational torque of the rotor of the AC generator 11 for the charge of the capacitor 51, and dispenses with the secondary battery, and the downsizing and the reduction of operation labor can be materialized.

Abstract: PROBLEM TO BE SOLVED: To make a power source automatically interruptible when an earthquake breaks out, by electrically interrupting the circuit between the input/ output terminals when external vibration is detected in one of three power circuit breakers mechanically detecting the vibration in the mutually orthogonal directions. SOLUTION: When an earthquake breaks out, a housing 11 is vibrated, this vibration is transmitted to a weight 37 via a plate spring 33, and the weight 37 is vibrated. Then, the inside end of the spring 33 is vibrated, and a connection plate 31 mounted here is vibrated. Since a conductive plate 15 is fixed to a supporting part 13, the connection plate 31 is separated from the conductive plate 15. Since an interruption plate 21 is moved inward by a coil spring 25, when the connection plate 31 is separated from the conductive plate 15, the interruption plate is advanced therebetween, in this way, the connection plate 31 and the conductive plate 15 are placed completely in a contactless condition. Thus by electrically interrupting between the two conductive plates 15 31, the circuit between input/output terminals is placed electrically in a non-conductive condition.

Abstract: PURPOSE:To enable a natural television screen to be obtained even when one person image is picked up by changing the opening/closing degree of a shutter, that means, as aspect ratio while corresponding to zoom control quantity. CONSTITUTION:A solid-state image pickup element 4 is disposed in an image pickup camera 2 for a High Definition Television(HDTV), the shutters 3a and 3b are disposed on the front surface of the camera 2 and an optical system such as a diaphragm or a lens is provided on the front surface of the shutter 3a and 3b. Then, a television signal having the aspect ratio which the width of the television screen is made to be longer than that of the television screen whose aspect ratio is 3:4 is outputted and simultaneously, a dimension D D1 D2 and the aspect ratio are changed by masking the image of the size D of a horizontal direction when the image of an object 1 is made incident on the element 4 with the aid of the shutters 3a and 3b corresponding to the zoom control quantity 12. Thus, the person image projected by being zoomed up with the aid of the image pickup camera of the HDTV is well matched with the size of the screen and it does not make unnaturalness to occur.

Abstract: PURPOSE:To use a channel selecting circuit common to plural channel selecting circuits and to simplify circuit constitution by providing nonvolatile memories corresponding to tuner units and storing channel selection voltages in the memories selectively. CONSTITUTION:By the specification of a commander 5, a tuner unit 3A among 3A-3C is selected and the output of a local oscillator 34A is led out alternatively through a switch circuit 41. The signal is frequency-divided previously by a prescaler 45 and frequency-divided at a frequency division ratio corresponding to a specified channel by a programmable counter 46 to have a specific frequency fP; and a phase comparator 47 makes a phase comparison between the output of a reference oscillator 48 and a signal obtained by frequency division 49. The output of the comparator 47 is converted by an A/D converter 51 into a digital signal, which is stored in a nonvolatile memory 53A through a gate 52A. The data stored in the memory 53A is D/A-converted by a converter 54A into an analog signal, which is supplied as a channel selection voltage to the oscillator 34 and an RF tuner 31A through an adder 55A to be used for selecting a desired channel.

Abstract: PURPOSE:To perform both the AM and FM wave detections with a simple constitution, by combining an AM wave detecting circuit with a PLL type FM demodulating circuit. CONSTITUTION:The FM modulated intermediate frequency TV signal given from a tuner 3 and the AM modulated intermediate frequency TV signal given from a tuner 7 are supplied to a common intermediate frequency amplifying circuit 10 via a changeover switch 13. The output of the circuit 10 is supplied to a PLL type AN/FM wave detecting circuit comprising an AM wave detecting circuit 14 and a PLL type FM wave detecting circuit 15. The intermediate frequency signal given from the circuit 10 and the oscillating signal given from an oscillator 27 are compared with each other through a phase comparator 28. Then an FM wave detecting output is obtained from the output of an amplifier 30. The signal obtained by giving a 90 deg. phase shift to the oscillating signal of the oscillator 27 is compared with the signal of the amplifier 10 through a comparator 18. Then an AM wave detecting output is obtained from the comparator 18.
