Title: Magnetic tape processor
Inventor: FURUYA TSUKASA
IPC: G11B20/18
Filed: 1981-08-17
Abstract: PURPOSE:To erase erroneous blocks only, by securing agreement between the count value of the tape traveling time between erasion mode and the writing mode in case the erroneous data block is erased when a writing error arises. CONSTITUTION:When data is written, the travel starting signal 11 of magnetic tape sets an FF4. The control signal lines 14 and 15 are kept at ''1'' and ''0'', respectively during a data writing mode. The ounter clock 13 is supplied to AND gates 5 and 6, and the gate 5 works in the data writing mode to start a counter 1. When the traveling of the magnetic tape is stopped, the FF4 is reset by a traveling stop signal line 12. Thus the counter 1 stops counting. If an error is detected in the written data, the magnetic tape is reset to the position set before the data is written. Then the written data block is erased. Under such conditions, the signal lines 5 and 6 are set at ''0'' and ''1'', respectively. The FF4 is set when the tape starts traveling, and the gate 6 works to start a counter 2. Then the FF4 is reset when the count value of the counter 2 is equal to that of the counter 1.

Abstract: PURPOSE:To obtain excellent durability and traveling property even in wide use environment without impairing S/N and track quality by forming a magnetic coated film contg. trialkyl phosphate and graphite or graphitized carbon on a base. CONSTITUTION:The magnetic coated film contg. the trialkyl phosphate and the graphite or graphitized carbon is formed on the base. If, however, the amt. of the trialkyl phosphate to be added is below 0.2pts.wt. per 100pts.wt. magnetic powder, the effect of maintaining lubricity is not sufficiently exhibited. If, conversely, the content exceeds 1.5pts.wt., there is the possibility that the output is degraded and missing pulses and extra pulses are generated. A slipping effect is not sufficiently exhibited if the amt. of the graphite or graphitized carbon to be added is below 2pts.wt. per 100pts.wt. magnetic powder. The mechanical strength of the magnetic layer is deteriorated and the wear resistance is not improved if, conversely, the amt. exceeds 100pts.wt.

Abstract: PURPOSE:To simplify the circuit constitution and installation works through decreased number of receiver circuits, by transmitting at least (>=3) different signal voltages to a receiver in accordance with the detecting state of a stator provided for each slave device. CONSTITUTION:Normally, voltages detected by gas sensors 14a and 14b are ea=eb=6V. A voltage detector 18 of a relay device 12b discriminates the  eb(=6V) and gives an output, a switch circuit 16 turns on and a voltage presence signal in 6V is transmitted to an output terminal 8b. On the other hand, a voltage detector 38 in a relay device 12a discriminates the signal voltage in 6V and gives an output, a switch circuit 36 turns on and transmits the ea(=6V) to the receiver via a signal line l1. If the sensor 14b detects leakage of gas and produces an eb(=12V), voltage detectors 18, 22 and 26 turn on switches 16, 20 and  24 and applies the eb(=12V) to a terminal 4a. In this case, a switch circuit 40 in the relay device 12a is turned on and the eb(=12V) is transmitted to the reception side. If the eb is zero, the signal line l1 also goes to 0V.

Abstract: PURPOSE:To enable automatic measurement of tritium without contact of collected water with a measurer by a method wherein part of water collected by a tritium sampler is made to flow into an agitation vessel and an agitated inspection liquid is collected in an inspection vessel. CONSTITUTION:By operating heat exchangers 1 and 2 of a tritium sampler 10, tritium in a sampling gas is caught and collected, together with water vapor, as water and stored in a collection tank 7. At the time of measurement of the tritium, water in a sampling tank 12 is drained by a piping 14 according to instruction from CPU 26 and a prescribed quantity of collected water is left in a collection pot 13. While the collected water in the collection pot 13 flows into an agitation tank 16, a liquid scintillator is made to flow into the agitation tank 16 beforehand, and they are agitated sufficiently with the rotation of an agitating propeller 19. The agitated inspection liquid is supplied to an inspection tank 21 through a solenoid operated valve 22 and, on the occasion, the inspection liquid emits fluorescence due to the tritium. Since this fluorescence is proportional to the concentration of radiation, the fluorescence in the inspection tank 21 is detected by a photomultiplier 25 disposed oppositely to the inspection tank 21, and the dose of radiation is measured therefrom.

Abstract: PURPOSE: To sufficiently push out particles scraped to a chute by diminishing magnetic attracting force of the particle directed to a scraper blade at every rotation of small area passing through a blade by a measure formed with a low magnetic resistant material bound to a shell and located in a drum. CONSTITUTION: A shunt bar 35 is located in a rotating drum 11 and reduces a magnetic field around a small area where a drum is located. The shunt bar 35 is made of low magnetic resistant material to shunt efficiently a magnetic field in the area. Every time the shunt bar 35 rotates under the scraper 30, the magnetic field penetrating the scraper 30 is periodically interrupted, and the scrap 18 built up on the slope scraper blade 31 is temporally released from the magnetic field. Resultantly the scrap 18 is pushed out by a diminished pushing force and is shoved towards the discharge chute. Consequently the separation of particles in the contaminated liquid becomes easy.

Title: Recharge circuit
Inventor: MORIMOTO YASUSHI
IPC: H02J7/10
Filed: 1988-05-30
Abstract: PURPOSE:To suppress fluctuation of output current, by feeding current branched from the drive coil of a transformer to a control circuit and varying the limit value of a control circuit when the source voltage increases. CONSTITUTION:Current branched through a diode 29 is smoothed through a capacitor 27 and a resistor 26 then the smoothed current is fed through a resistor 20 to a resistor 24. Consequently, the current flowing through the resistor 24 is the sum of current branched from the emitter current of a transistor 10 and the current branched from the drive coil 28b of a transformer 28. The diode 29 connected with the drive winding 28b, the capacitor 27 and the resistors 26, 20 constitute a constant resistance circuit, and the current flowing through the constant resistance circuit is proportional to the voltage across the drive winding 28b. Since the peak value of emitter current flowing through the transistor 10 varies to cancel the variation of output current caused through variation of source voltage, output current can be held at a constant level.
