Title: Tape driving controller
Inventor: YOSHINO TADASHI
IPC: G11B15/48
Filed: 1982-12-03
Abstract: PURPOSE:To reduce both capacity and breakdown strength of an electrolytic capacitor of a power supply circuit for power failure and to reduce the cost and the space for a tape driving controller, by detecting the generation of a power failure during the tape travelling and switching the generated torque to make it smaller in the power failure mode than in the normal mode for both supply and take-up side reel motors. CONSTITUTION:A power failure is detected by a power failure detecting circuit 25, and the power supply of a control circuit is switched to the output of a power supply circuit 24 for power failure from that of a power supply circuit 23 for normal use by the 2nd switch circuit 26 and with the output of the circuit 25. At the same time, the detection values of supply and take-up side winding diameter detecting circuits 33 and 36 are held by the output of the circuit 25, and also the torque setting is switched to the power failure mode form the normal mode for supply and take-up side torque setting circuits 34 and 37. Thus the power supplies of supply and take-up side reel motors 7 and 8 are backed up for a magnetic tape 2 which is driven out with the rotational energy of a capstan 10 in case a power failure is produced during the tape traveling mode while the capstan 10 is in a press contact with a pinch roller 11. This eliminate the tape sag which is produced in a power failure mode.

Title: Mass flow meter
Inventor: MIYATA YASUSHI
IPC: G01F1/84
Filed: 1989-08-18
Abstract: PURPOSE:To protect sensor tubes when used for flow rate measurement of high-viscosity fluid by providing an interlock circuit which stops flow rate measurement when the temp. detected by a temp. sensor is lower than a set temp. CONSTITUTION:Coriolis force is generated and the sensor tubes 5, 6 oscillate when the fluid flows in the sensor tubes 5, 6. The oscillation is detected by pickups 10, 11, by which the time difference/voltage conversion 20 and voltage/ frequency conversion 21 of the oscillation are executed. A flow rate signal is detected via a flow rate computing circuit 22. The flow rate signal is subjected to a temp. correction via the temp. sensor 24, a resistance/voltage converting circuit 25 and a temp. correcting circuit 26. A comparator circuit 30 compares the output voltage Va from the circuit 25 and the output voltage Vb of the circuit 25 and the output voltage Vb of the circuit 25 corresponding to the temp. at which the possibility of the deformation and rupture of the sensor tubes 5, 6 arises on increasing of the viscosity of the fluid. The circuit outputs a signal when Va<Vb. An interlock circuit 32 is operated by the output from the circuit 30 to stop a pump 3 and to open a stop valve 4 as well as to display 33 that the flow rate measurement is inadequate.
