IPC: H04B3/23
Filed: 1984-09-11
Abstract: PURPOSE:To shorten a focussing time, by changing the correcting quantity of the tap factor of an adaptive filter in accordance with the scale of the multiplied mean value of the code of an echo replica by the code of the difference signal between a received signal and the echo replica. CONSTITUTION:A binary data sequence from a terminal 1 is converted into transmitting line codes at a transmitting section 3 and, at the same time, supplied to an adaptive digital filter (ADF)6. The transmission line codes from the transmitting section 3 are sent to a two-wire transmission line 20 through a hybrid 4. At the ADF6, an echo replica corresponding to the echo component of a transmitting signal is produced and the replica is inputted in a subtractor 8 after D/A conversion 7. At the subtractor 8, a received signal obtained by subtracting the echo replica from the mixed signal of a received signal and an echo component is outputted and sent to a receiving section 17. The code of the received signal detected by a code detector 9 and the code of the echo replica detected by another code detector 10 are multiplied by each other 11 and the correcting quantity of the tap factor of the ADF6 when a signal exists is changed in accordance with the averaged absolute value 13 of the multiplied result. When no signal exists, the tap factor correction is stopped.

Filed: 1986-08-13
Abstract: PURPOSE:To send out a pseudo phase signal by a simple constitution, and to improve the work efficiency by slowing up the speed of a pulse motor so that the rotational position of a transmitting drum and a pseudo phase are synchronized. CONSTITUTION:By a pseudo phase signal generating means 1b, the pseudo phase signal is generated, irrespective of rotational driving of a transmitting drum, and it is sent out to an electric circuit as a phase signal (a joint signal of a transmitting original wound to a transmitting drum 11).

Title: Engine starter of automobile
Inventor: TODA TOSHIHISA
IPC: F02N11/08
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent a starter motor from starting during the running of an engine. SOLUTION: When an engine starting command is given by means of remote control, a relay switch 17 of a starting relay 13 is turned on for a specified time, and a starter 7 gets starting. When an engine runs with the starter going on, a high level signal is inputted into an H active input terminal of an AND circuit 39, and simultaneously with the relay switch 17 turned off, a low level signal is inputted into an L-active terminal. Therefore, the high level signal is given to a delay circuit 40 from the AND circuit 39, so this delay circuit 40 makes a relay switch 28 of a manual start prohibiting relay 27 into being turned off after the elapse of the specified time. In this state (during engine running), even if a start switch of an ignition switch unit 1 is turned to (ON, the starter motor 7 is not energized with current.

Title: High pressure sodium lamp
Inventor: SAITO NAOKI
IPC: H01J61/56
Filed: 1984-09-12
Abstract: PURPOSE:To prevent any decrease in the life of the stabilizer by connecting the emitter tube in series with a body consisting of a resistor for heating and breaking a glass case charged with oxygen and a thermoresponsible switch which is open during lighting of the lamp (these two members are connected parallel to each other) and installing these members in the outer tube. CONSTITUTION:Conductors 2 and 2 made of niobium and having an electrode in their end, are fused to the ends of an emitter tube 1. An outer tube 4 is evacuated to produce a hard vacuum. The interior of a glass case 6 is charged with oxygen at 3 atmospheric pressures and a resistor 7 is wound around the outer surface of the glass case 6. During the time when the lamp is in a stable state, a thermoresponsible switch 8 is opened by the heat of the emitter tube 1 and therefore a current flows in the resistor 7. When the lamp current abnormally increases due to a starting rare gas flowing out from the emitter tube 1, the resistor 7 becomes red-hot to break the glass case 6 and to cause the internal oxygen gas to flow into the outer tube 4 thereby oxidizing the conductors 2 and 2'. As the result, the electric conduction between the conductors 2 and 2' and emission tube supporters 3 and 3' is blocked, thereby preventing the operation of the emitter tube 1.

Title: Method for cooling continuously cast slab
Inventor: OSHIMA KENJI
IPC: B22D11/20
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To adjust cooling water quantity in the wide range without changing the existing nozzles by repeating the spraying of the cooling water and the stop of spraying at fixed time intervals when a cast slab from a water-cooling mold is cooled with the water spraying composed of the nozzle group in plural zones while supporting the cast slab with support rolls. SOLUTION: The repetition at fixed time intervals is desirable to execute individually in each zone and only to the inside of curvature by forming a continuous caster 10 to a bending type or a vertical and bending type. In case of executing the repetition only to the inside of the curvature, the excess cooling portion developed on the inside of the curvature is reduced and the development of crack is restrained and the surface crack at the shape straightening time, is prevented. Then, the cooling water 7 from the nozzles disposed in plural numbers along the width direction of the cast slab 9, is sprayed and the spray is stopped at the fixed time intervals to the cast slab 9. The water quantity sprayed to the cast slab 9 can widely be changed by changing the time interval into various values. Such time interval that the support rolls supporting the cast slab 9 do not break, is set.  The time interval is desirable to be 1-10 sec.

The wire core 2-c of the end part A is directly connected to the wire core 7-a of the other end part B, and a toroidal core 1 is penetrated by the output current of the fixed current source 6 through each wire core. When the current of the output line 2 is increased, the core 1 is saturated, and a voltage V0 is induced in the terminal of a coil 3. When the voltage V0 exceeds the electric discharge starting voltage of the electric discharge lamp 4, the electric discharge lamp 4 is lighted. The voltage generated by the coil 3 depends on the number N2 of winding of the coil 3. When the wire cores are connected in the abovementioned manner, the number N2 of turns is increased. The amount of current run under a condition where the electric discharge lamp 4 can move freely, is reduced, while the electric discharge lamp 4 can be lighted at high wattage.
