Title: Push-pull circuit
Inventor: YOSHIKAWA ASAO
IPC: H03F3/30
Filed: 1993-01-08
Abstract: PURPOSE:To obtain a push-pull circuit capable eliminating distortion in an output waveform while suppressing power consumption for the entire output. CONSTITUTION:When a signal voltage to be outputted to an external load is applied from an input terminal 12 to based of a couple of NPN transistor(TR) Q1 and a PNP TR Q2 connected in common, voltages shifted by + or -1VBE with respect to an input signal level are generated in emitters of the TRs Q1, Q2 and given respectively to bases of a push TR Q4 and a pull TR Q3. Thus, the TR Q4 is turned on when an input signal is positive, from which a current nearly equal to a collector current IC4 is outputted, and the TR Q3 is turned on when an input signal is negative, to which a current nearly equal to a collector current IC3 is received, and then a signal of the same waveform as that of the input signal is outputted.

Title: Object extracting device
Inventor: NINO YUICHI
IPC: G06T7/00
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To highly accurately extract an object without being influenced by the difference in the texture between a background and a moving object, brightness or the like. SOLUTION: Inter-pixel correspondence stored in a correspondence storage part 3 is checked for all pixels of plural images inputted from an image input part 1. Then the luminance values of these pixels are calculated by a luminance calculation part 7. Based on the calculated luminance values, a threshold decision part 8 selects the mean value of differences between pixels having corresponding relation and a deviation from the mean value out of contents stored in a mean storage part 51 and a deviation storage part 52. An area detection part 6 calculates a difference between corresponding pixels and obtains a deviation from the selected mean value. When the deviation is larger than the selected deviation value, these pixels are detected as pixels losing their correspondence.

Title: Power unit for guard
Inventor: MATSUSHIMA MASAKAZU
IPC: H02H3/087
Filed: 1991-01-11
Abstract: PURPOSE:To easily confirm the magnitude of a load current flowing to a power unit for guarding and, at the same time, to lower the output voltage of the power unit to 0V when an overcurrent is generated. CONSTITUTION:A control circuit 15 detects the magnitude of a load current and turns on a load current indicator lamp 18 in accordance with the detected result. When an overcurrent is generated, the circuit 15 works upon a stabilization circuit 12 to lower the output voltage to 0V and, at the same time, turns on an overcurrent indicator lamp 19 and makes an abnormality alarm output terminal T2 to generate an output signal to the outside. Accordingly, the currently flowing load current can be recognized easily from the lamp 18 and whether or not an overcurrent is generated can be easily discriminated from the lamp 19. In addition, since the DC output is lowered to 0V when the overcurrent is generated, the fault of a power unit for guarding can be prevented. Moreover, the generation of the overcurrent can be easily detected from a place far from the installing place of the power unit for guarding by utilizing the output terminal T2.

Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain an inquiring search system which can be realized by using a quick portable terminal which saves consumption power. SOLUTION: A signal from a position measuring satellite 16 constituting a system of a GPS or the like is received by using both a portable terminal 12 held with a moving member 10 and a master apparatus 14 which is fixedly arranged. The portable terminal 12 searches the position measuring satellite 16 which can be tracked in accordance with a command from the master apparatus 14, and answers the result to the master apparatus 14. The master apparatus 14 demodulates a satellite orbit information or the like from a satellite signal, and calcurates or presumes a position of the portable terminal 12 by refering to the information from the terminal 12. Since demodulation of the satellite signal by the portable terminal 12 is unnecessary, quick processing and consumption power saving are enabled.  When the number of visual satellites is little, position presumption may be performed by using a base station of a PHS system or the like.
