Inventor: TAKAHASHI YOSHIHIKO
IPC: B41J33/52
Filed: 1988-04-14
Abstract: PURPOSE:To efficiently use a transfer medium, by a method wherein feed tension is applied to a transfer medium to detect a tension value and the unwinding amount of the transfer medium is detected on the basis of said value to unwind the transfer medium corresponding to the detection result. CONSTITUTION:An ink ribbon 2 is pulled upwardly by the tension force of a spring 11d to receives front tension. A carriage motor 4d and a ribbon motor 9e are drive forwardly to move a carriage 4 in an A-direction and the ink ribbon 2 is successively delivered from a supply reel 1c to be taken up by a take-up reel 1e.

Title: Vibration-sensitive power-cut-off device for oil supply device
Inventor: KOBAYASHI KENJI
IPC: B67D7/32
Filed: 1995-03-23
Abstract: PURPOSE: To prevent oil from being supplied except that safety is confirmed and a return switch is operated 'by a method wherein a magnetic storage type contact is set to OFF when a vibration responsive switch is turned off and such condition is maintained. CONSTITUTION: When an impact is exerted on a casing of an oil supply device due to an earthquake or collision of car, a vibration responsive switch 25 is set from ON to OFF, and hence a set coil S is demagnetized. As a result, the exciting force of a reset coil R becomes larger so that a first and second contacts SR1, SR2 are set to OFF and thereafter such conditions are maintained. And at the same time, since the contact SR2 is set to OFF, a power relay 41 also is set to OFF and hence power to a control device 8 is cut off and a motor control switch 10 also is set to OFF and supply of liquid is suspended. As a result, even if power failure is eliminated and power supply is restarted, suspended condition can be maintained. However, if a return switch 29 is depressed under such conditions, the set coil S is excited and the contacts SR1, SR2 are set to ON and oil can be supplied.

Abstract: PURPOSE:To enable a recognition of regions based on inaccurate data in a functional information picture by indicating regions, which are detected by an abnormal region detection device, in the functional information picture under controls of an indication control device. CONSTITUTION:In an arithmetic unit 21, an intensity distribution of hemoglobin is obtained by a combination of a logarithmic conversion circuit 23, a subtraction circuit 24 and an addition circuit 25.

IPC: H02M1/00
Filed: 1978-07-25
Abstract: PURPOSE: To prevent an unnecessary stopping operation by putting a detection circuit in insensitive condition when overshoot of real current or pattern current varies abruptly.  
     CONSTITUTION: Three output pulses 17, 19 and 21 from a first, second and third monostable multivibrator circuit 17, 19 and 20 are applied to an OR gate 22 to obtain their logical sum output 22. When amplifying said output 22 to pattern current 10-d and adding, an output 23 which has very high constant level when anyone of the three output pulses 17, 19 and 21 occurs while changes similarly with pattern current in other case is obtained. When subtracting 12-d which is obtained by full- wave rectifying said output 23 from that obtained by full-wave rectifying the real  current in a subtractor 14, a signal 14-b is obtained which is drawn significantly  when the polarity of the pattern current is switched or in case of abrupt change of  the pattern current. Therefore, the difference between the output and pattern currents becomes great to avoid an operation of the detection circuit 15.

Abstract: PURPOSE:To perform surely the reset operation at a power rise time by providing a detector which detects that a power source voltage reaches a certain voltage and setting an FF, which outputs an internal reset signal, with this detection output. CONSTITUTION:When a power source VDD rises, a clock phi for synchronism is outputted after a prescribed time. A reset input signal inversion Re is so set that it becomes the reset release designation state after clock oscillation. When the voltage VDD rises to a voltage, with which an FF 2 and a differential amplifier 3 can be operated, and reaches a reference voltage E0, a detection output Vr becomes low-level, and therefore, the FF 2 is reset, and an internal reset signal inversion Ri becomes loe-level, and the unit inside is in the reset state. When the voltage VDD exceeds the voltage E0, the output Vr becomes high-level, and reset to the FF 2 is non-active. When the signal inversion Re becomes high-level thereafter, the signal inversion Ri becomes high-level also synchronously with the rise of the clock phi, and reset of the unit inside is released.
