Title: Trigger demodulation system
Inventor: MURAKAMI SUMINORI
IPC: H04L25/38
Filed: 1988-01-14
Abstract: PURPOSE:To enable reproduction with a single demodulation circuit by a method wherein a code of a coding radar trigger signal is predetermined and a pattern matching of a code is performed when a signal is received to transmit a number of radar trigger signals with a single transmission path. CONSTITUTION:Two kinds of coding radar trigger signals are inputted into a trigger signal receiving/reproducing circuit 1 to be amplified 20 and shaped 21 in the waveform and outputted as signal C. The signal C is taken by a clock A in a start-stop synchronization circuit 2A and outputted as synchronous comparison signal E. A start-stop synchronous clock F is outputted from the circuit 2A. The signal E is stored with a shift register 2B by a pulse timing of the clock F. Then, a pattern judging circuit 3 determines whether two kinds of repeated patterns stored in the register 2B coincide with a predetermined repeated pattern and matching signals H and I are generated. In signal correction circuits 4A and 4B, monostable multivibrators 24A and 24B operate in response to the signals H and I to generate pulses (f) and (h) with a fixed width, which are amplified 25A and 25B and then, radar trigger signals (g) and (i) are outputted.

Title: Electronic switch
Inventor: MIYAMOTO KIYOSHI
IPC: H03K17/082
Filed: 1984-01-18
Abstract: PURPOSE:To obtain an electronic switch restoring short-circuit automatically by providing a display device or the like placed on a rapid charging circuit of a trigger circuit, lighted at the detection of an object and also flickered at a period based on the difference between the charging current of the charge circuit and the holding current of a thyristor at short circuit to inform the short-circuit state. CONSTITUTION:It is supposed that an object approaches a proximity switch with a load L short-circuited. Then a sensor circuit outputs an NL output and a large current flows to a thyristor 6 and an FET7. Since a current and voltage given to the sensor circuit 10, however, are decided to a prescribed voltage by a constant voltage circuit 9, the short-circuit current is limited to a prescribed value by the constant current characteristic of the FET7. The power voltage of the sensor circuit 10 repeats rising/falling at a prescribed cycle and a light emitting diode 15 for operation display is flickered accordingly. The cycle is set to, e.g., 1.5sec by adjusting the resistance value of a resistor R22. Thus, the operation of a short-circuit protection circuit is informed to the user in this way.

Filed: 1987-01-14
Abstract: PURPOSE:To facilitate adjustment of transmission and shielding of light by forming a thermal change rate response member, the transmissivity of which increases with slow cooling after heating and decreases with quick cooling and providing heating and cooling means for heating, quick cooling and slow cooling of said members. CONSTITUTION:A light transmitting and shielding board 1 is formed of flat plate-shaped response glass 2 into which a thermal change rate response material is incorporated and hot wires 3. The transmissivity change characteristic of the glass 2 varies with the characteristics of the materials incorporated therein. For example, the transmissivity decreases to 10% when the board 1 is heated to the temp. above the threshold value by the hot wires 3, if the transmissivity of said board is 80%. The glass 2 is quickly cooled and maintains the transmissivity to shield the light when the operation of the hot wires 3 is quickly stopped. To restore the transmissive state, the glass 2 is heated to the threshold value or above and the working temp. of the hot wires 3 is gradually lowered, then the transmissivity of the lens 1 increases to 80%. The transmission and shielding of the light are thereby adjusted as desired.
