Title: Clock down detection circuit
Inventor: OKURANO TSUTOMU
IPC: H04M3/22
Filed: 1988-02-29
Abstract: PURPOSE:To detect a clock fault without setting a time constant corresponding to a clock frequency by combining an FF, a counter, and an OR gate. CONSTITUTION:When a system synchronizing clock 18 via a line 1 goes down at a time of arrow head and set at logic '1', a toggle FF 4 stops its operation, and its output, that is, reset signals 20 and 21 go to constant values. Assuming that the signal 20 is set at the logic '1' and the signal 21 at logic '0', the counter 7 always goes to a reset state, and the counter 8 is set at a state always possible to step. As a result, the counter 8 steps at every input of a clock 19, and when a fourth clock is inputted, the output goes to the logic '1'. Therefore, the OR gate 9 sends a detection signal 22 with the logic '1' to a clock display device at this time, and informs the abnormality of the clock. Also when the abnormality is generated in the clock from a line 2, the same operation is performed.

Title: Dc-ac inverter power circuit
Inventor: MORIWAKI MASATO
IPC: H02M7/48
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To lessen a transistor insertion loss of a series regulator circuit by inserting a circuit of a diode, a capacitor, and a resistor which rectifies the voltage waveform at a connection between a DC-AC inverter circuit and a choke coil and then supplies base current to a transistor of the series regulator circuit. SOLUTION: A transistor 3, a resistor 4, and a Zener diode 5, which constitute a series regulator circuit, are connected to an input power line of a DC-AC inverter circuit 1. As the base current of the transistor 3 of the series regulator circuit 3, the voltage obtained by rectifying the AC voltage at the connection between the DC-AC inverter circuit 1 and a choke coil 2 by a diode 10 and a capacitor 11 is supplied to the series regulator circuit through a resistor 12. By this method, the effect by the voltage between the base and the emitter of the transistor 3, which has been inevitably appearing as an insertion loss of the series regulator circuit in conventional circuits, can be neglected.

Title: Picture recording system
Inventor: KINOSHITA TAKAO
IPC: H04N9/793
Filed: 1983-03-16
Abstract: PURPOSE:To ensure satisfactory image resolution to a picture which requires the image resolution by controlling a recording means to switch the recording style of the picture signal in response to a selecting means for the type of a recorded picture signal. CONSTITUTION:An input picture signal is separated into a luminance signal Y and a chrominace signal C through a Y-C separating circuit 2. The signal Y is modulated by an FM modulator 3 so as to be distributed to a comparatively high band and then supplied to a mixer 5 after its low band component is cut by an HPF4. While the signal C undergoes the frequency conversion 6 to be supplied to a low band and is supplied to the mixer 5 via a gate circuit 7. Both signals Y and C are mixed by the mixer 5 and supplied to a head 9 via an amplifier 8 to be recorded on a magnetic tape 10. The circuit 7 cuts off the signal C under the control of a sequence circuit 12 when a mode changeover switch 11 selects a white/black TV signal. The modulator 3 is controlled to increase the band of the signal Y. The cut-off frequency of the HPF4 is lowered to control even a low frequency component passes through the HPF4. Thus high image resolution is obtained witha white/black TV.

Abstract: PURPOSE:To realize a simple dielectric filter with integrated structure having a higher harmonic suppression effect by providing a hole for coupling whose hole diameter is varied in step shape or tapered shape between holes for resonance formed in a dielectric block. CONSTITUTION:The holes 21-23 formed in a rectangular parallelo-piped dielectric block 11 varied line impedance partially and shifts a frequency for spurious resonance by odd times by varying the hole diameters of the holes 31 and 32 for coupling in the step shape or the tapered shape.

Abstract: PROBLEM TO BE SOLVED: To detect stable inter-frame correlation from input signals and to surely perform frame frequency conversion by detecting the inter-frame correlation of the image signals, whose noises are eliminated by a nose filter and then surely performing the frame frequency conversion. SOLUTION: A noise filter 11 eliminates the noises of image signals and generates the noise-cut image signals. The filter 11 is a space filter which performs a closed filtering process in a frame, and the correlation is secured with use of this space filter. An inter-frame correlation detection means 12 detects the inter-frame correlation of the noise-cut image signals and detects the overlapping fields. A frame frequency conversion means 13 deletes the overlapping fields form the noise-cut image signals and performs the frame frequency conversion. Thus, the means 12 performs the stable inter-frame correlation detection without being affected by noises, etc. and is able to detect the overlapping fields of image signals.
