Title: Frequency discriminating circuit
Inventor: UYAMA SEIICHI
IPC: G01R23/15
Filed: 1981-05-21
Abstract: PURPOSE:To automatically discriminate the change in an AC power supply frequency with simple constitution, by dividing the AC power supply voltage with a capacitor and a resistor and using the divided voltage as a compared input voltage for a comparator after rectifying and smoothing. CONSTITUTION:Between lines 1 and 2 connected to an AC power supply, a series circuit consisting of a capacitor 3 and a resistor 4 is connected. A voltage divided with the capacitor 3 and the resistor 4 is rectified with a diode 7, smoothed at a capacitor 8 and given to a comparator 5 as a compared input voltage. Further, the AC voltage between the lines 1 and 2 is rectified at a diode 13, smoothed at a capacitor 14, divided with voltage dividing resistors 9 and 10 and given to the comparator 5 as a reference voltage. Since the AC impedance of the capacitor 3 is correlated with an AC impedance frequency, the compared input voltage is changed according to the fluctuation of the AC frequency. Then, the reference input voltage is set to a value intermediate between the compared input voltage at, e.g., 60Hz and 50Hz. Thus, the question whether the power frequency is 50Hz or 60Hz can be discriminated.

Abstract: PURPOSE: To reliably control a stop position, by a method wherein a variable throttle, in which control valve chambers are coupled to a subcylinder mechanism through the medium of a control valve, is connected to a main flow path provided with a throttle.  
     CONSTITUTION: A variable throttle 10, in which control valve chambers 25 and 26 switch-controlling a valve body 13 are coupled to a subcylinder mechanism 2 through the medium of a control valve 30, is connected to a main flow path 7 equipped with a throttle 8.

Title: Automatic running robot
IPC: G05D1/02
Filed: 1992-03-31
Abstract: PURPOSE:To accurately correct a travel distance by installing a marker which has no position data in a travel route and then securely reading out position data corresponding to a marker when the marker is detected. CONSTITUTION:During the travel of the automatic running robot 1, its correcting means 11 reads a permitted section B out of a marker data table and judges whether or not the robot travels in the permitted section B from the current travel distance. The travel in the permitted section B is detected as a result of the judgement and when the marker M is detected at this time, the correcting means 11 corrects the travel distance. Consequently, the automatic traveling robot 1 travels along the travel route. If the marker M is not detected during the travel in the permitted section B and this marker nondetection exceeds a reference value, the automatic traveling robot 1 generates an abnormality signal by an abnormality signal generating means 11.

Title: Synchronous separation device
Inventor: KAARU RUDORUFU KOBURITSU
IPC: H04N5/08
Filed: 1993-03-01
Abstract: PURPOSE: To dynamically set a slice level. CONSTITUTION: A signal slicer 103 of synchronizing separator includes a comparator 29 and generates an output signal according to the difference between a video signal VIPC, for which a black level is outputted, and a slice level VSLICE. The slice level is dynamically set between the maximum value of a synchronization pulse and the black level, according to a maximum level VIPC of the synchronization pulse. When the synchronization pulse is generated in the video signal, the output signal of signal slicer 103 is turned into an active 1st logic state. Between the continuously generated synchronization pulses, conversely, the output signal is turned into an inactive 2nd logic state. In order to prevent the generation of 1st logic stage during the reception of no video signal, the slice level is set fixed at a predetermined level.
