Abstract: PURPOSE:To discriminate the position of the end of write of a tape by providing a magnetic tape device with a mechanism which drives a magnetic tape take-up shaft in the axial direction, and operating this driving mechanism for a prescribed time to wind the tape when the write on the tape is terminated. CONSTITUTION:An axial supporting part 4 of a take-up shaft 5 is supported in a sliding part 3 and is slided in the axial direction in the sliding part 3, and the axial supporting part 4 and the take-up shaft 5 are stored in the sliding part 3. The axial supporting part 4 is slided in the sliding part 3 in the transverse direction on the figure. A tape 1 is placed near a front plate 2 by a spring 6. When a motor 9 is operated, the axial supporting part 4 is slided toward the front plate 2 against the spring 6 through a lever 7 by a high mountain part of a cam 8, and the tape 1 is moved away from the front plate 2. Consequently, the winding position of the magnetic tape 1 is disturbed longitudinally while the tape is placed in this position. This state is applied to the end of the write on the magnetic tape to discriminate the write end position.

Filed: 1987-05-15
Abstract: PURPOSE:To transfer data to the succeeding stage and subsequent stages even if a fault is generated in the CPU by transferring an input data signal to the succeeding device and the subsequent stage by by-passing the CPU at the time of generating a fault in the CPU. CONSTITUTION:An input data signal 1 is inputted to the CPU 2, which processes the signal 1 in accordance with necessity and outputs an output data signal 3. On the hand, a fault detecting circuit 4 monitors the state of the CPU 2, and at the time of detecting a fault in the CPU, outputs a fault display signal. A selecting circuit 6 inputs both signals, 1, 3, usually selects and outputs the signal 3, but when the CPU fault is generated and the signal 5 is inputted, selects and outputs the signal 1 by bypassing the CPU 2. Consequently, data can be transferred to the succeeding stage and the subsequent stages even if a CPU fault is generated.

Filed: 1979-09-18
Abstract: PURPOSE:To prevent the frosting of an evaporator and give full play to the cooling capacity in a car cooler by providing a circuit to stop a refrigerant compressor when the temperature of the air on the blow-off side of the evaporator is maintained under a temperature a little higher than a fixed value for a fixed time as well as the same temperature is lowered as far as this fixed value. CONSTITUTION:A comparison amplifier OP1 is brought to a low-level output when the air temperature on the blow-off side of an evaporator is lowered to a fixed value T1 by the detection output of a thermistor Th1, while a comparison amplifier OP2 when the same temperature is lowered to a fixed value T2 lower than T1. The amplifier OP2 is brought to a high-level output when the temperature is raised to a fixed value T3. When the amplifier OP1 is brought to the low-level output, a comparison amplifier OP3 is brought to a low level after a fixed time by a delay circuit composed of a resistance R7 and a condenser C. At this stage, since the amplifier OP2 is also brought to the low level by a diode D2, a refrigerant compressor is stopped until the temperature on the blow-off side is raised to T3, and during this stoppage, defrosting is carried on. When the temperature on the blow-off side is again raised above T1 within a fixed time after being lowered to T1, the amplifier OP1 is returned to the high level via a diode D1 and started to operate when the temperature is again lowered to T1.
