Title: Coil shortcircuiting sensing device of solenoid-operated drive valve
Inventor: YANAGIUCHI AKIHIRO
IPC: F01L3/24
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a coil shortcircuiting sensing device for solenoid-operated drive valve of such a structure that the coil current is feedback-controlled, thereby, a coil shortcircuit can be sensed accurately. SOLUTION: The current fed to a solenoid coil is feedback-controlled by a control circuit. Until a timer tim attains a specified time rest (Step 120), a counter cnt is incremented every time the flag edge is put on (Steps 124 and 126). The flag edge is put on when the large-small relation between the sensed amperage Imon in the solenoid coil and the reference value Iref is inverted. If the counter cnt attains the specified value fail, judgement is determined that the solenoid coil 100 is in shortcircuiting (Steps 130 and 132).

Title: Magnetic bubble storage device
Inventor: MATSUYAMA KIMIHIDE
IPC: G11C11/14
Filed: 1982-09-03
Abstract: PURPOSE:To transfer bubbles between the first transfer path and the second transfer path on two ways, by providing a means which can supply the first current pulse and the second current pulse, whose polarity is different from that of the first current pulse, to a conductor pattern on a magnetic bubble element at an interval of a prescribed time. CONSTITUTION:When a bubble comes to a position 16, a rotating magnetic field is directed to an arrow 7. When a bipolar current pulse supplying means 5 is used to apply the first current pulse directed to an arrow 40 to a conductor pattern 3 with this phase, a bias magnetic field distribution is induced in the gap part between the first transfer path 1 and the second transfer path 2 because of the disturbance of a current distribution which is generated by the first notch 13 and the second notch 14 provided in the conductor pattern 3. By this bias magnetic field distribution, the bubble in the position 16 is transferred to a position 17. Thus, the bubble is transferred on two ways between the first and the second transfer paths 1 and 2, which are formed at the interval, with a simple element constitution.

As a result, the fall of the sheet body to an undesired position is arrested.
