Title: Data slicing circuit
Inventor: SHIKA TOMOHIRO
IPC: H04L25/40
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To extract data in a random data area used by a user correctly as digital binary data string by deciding a reference value obtained by integrating a demodulated base band analog signal within a preamble area. SOLUTION: A base band analog BA signal extracted by a radio demodulation part 2 is transmitted to a comparator 7 and a switch 6. The switch 6 is closed and opened by H/L of a slice control signal from a control part 3 and at the time of closing, the BA signal is integrated by a resistor 10 and a capacitor 11 and appears at the negative side measuring point 9 of the comparator 7. When the switch 6 is in a closed state, the hold voltage of a voltage value at the time point when the slice control signal is switched from H to L appears at the positive side measuring point 8 of the comparator 7. The comparator 7 compares the BA signal and the hold voltage, and 1 is outputted to the comparator 7 when the BA signal is high but 0 is outputted when the BA signal is low to make a binary data string to send to the control part 3 through a transmission line 13.

IPC: G01P3/64
Filed: 1979-03-06
Abstract: PURPOSE: To monitor the fault of sensors themselves by measuring the duration time of the detection signals of two sensors and the time width between detection signals of both sensors in a unit which detects that a moving object moving between two points on a running path exceeds a prescribed speed.  
     CONSTITUTION: The delay time of timer relays 6 and 7 is set longer than the one- time detection time of moving object passage for normal passage sensors 100 and 200 provided at two points. In case that passage sensors 100 and 200 continue operating over the delay time, contacts 6a and 7a are closed to set keep relay 5, thereby detecting that passage sensors 100 and 200 are faulty. The delay time of timer relays 8 and 10 is set longer than the time required for running of the moving object between two points in a prescribed speed. If passage sensor 200 does not operate within the delay time after passage sensor 100 operates, the fault of passage sensor 200 is detected; and if passage sensor 200 operates immediately after passage sensor 100 operates, the fault of passage sensor 100 is detected.

Abstract: PURPOSE:To improve the efficiency of a metal vapor electric-discharge lamp by increasing the coldest temperature of the emission tube without deteriorating the output of emission from the arc by installing an under cover consisting of an upper and a lower cover near the emission tube. CONSTITUTION:Near the end of an emission tube 1a located in its bottom during lighting, a light-transmitting under cover 6 is installed which covers at least the lower end. The under cover 6 consists of an upper cover 6a and a lower cover 6b. The upper cover 6a may be prepared by cutting the ends of a quartz tube to a given length. Because the size of the lower cover 6b is smaller than the conventional one, the lower cover 6b can be easily formed either by heating with a burner or by metal molding. As a result, manufacturing of a metal vapor electric-discharge lamp is facilitated. Furthermore, the coldest temperature of the emission tube 1a is increased, thereby improving the efficiency of the lamp.
