Title: Surge current detecting device
Inventor: WAKABAYASHI TAKEO
IPC: H01T15/00
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To obtain information on surge currents simply and reliably by providing a fuse serially connected to a surge absorbing device and a varistor element connected to the fuse in parallel. SOLUTION: When a lightning surge at a level of the impulse wave discharge starting voltage of a gas-filled arrester 21 or greater, for example, arrives at a communication line I1 , the gas-filled arrester 21 connected to the communication line I1 conducts and discharges surge energy to a ground 3. The fuse- element of a fuse 11 is fused by a surge current at this time. At the time when surge energy remains even after fusing, the resistance value of a varistor element 12 instantly becomes low sufficiently, and the surge current is commutated to this, passes through a serial path between the varistor element 12 and the gas-filled arrester 21 and is absorbed. As the commutation to the varistor element 21 at this time is extremely smooth, no arc occurs at a location where the fuse 11 is fused to prevent insulation breakage in communication facilities 2 and a line support.  In addition, as the fusing of the fuse-element of the fuse 11 can be visually recognized, it is possible to know which surge absorbing device the surge absorption belongs to simply and reliably in a short time.

Title: Tape taking-up device
Inventor: YAMASHITA KOJI
IPC: G11B15/43
Filed: 1987-11-27
Abstract: PURPOSE:To make driving torque smaller which becomes necessary to switch a reel stand to be rotated and driven by providing a sector gear, to which an idler gears when an arm oscillates, between two reel bases. CONSTITUTION:Between two reel bases 2 and 3, a sector gear 23, to which an idler 7 gears when an arm 20 oscillates, is provided near the idler 7 both edges of which are placed at positions to rotate and drive the reel stands 2 and 3. Consequently, since frictional resistance force is not used when the idler 7 is oscillated in order to switch the rotating and driving of the reel stands 2 and 3, it becomes sufficient to give the driving torque only for rotating and driving the reel stands 2 and 3 to a center pulley 5. Thus, the output torque of a driving source can be smaller, the title device can be manufactured at a lower cost, and further, a wow and flutter value can be improved by making a reduction ratio bigger.

Title: Operation data controller
Inventor: SUZUKI YUKIHIRO
IPC: G05B15/02
Filed: 1993-11-30
Abstract: PURPOSE:To increase the service life of a semiconductor nonvolatile memory with reduction of the storing frequency of the operation data by storing the operation data in the nonvolatile memory when a prescribed time passed after a switch operation is discontinued. CONSTITUTION:A child lock switch 11, a 3h-off timer switch 12, a save operation switch 13, a DOWN switch 14 and an UP switch 15 transmit the ON signals 110-150 to a control circuit 3 when these switches are pushed. An E<2>PROM 2 stores the precedent set value or the initialization value. Then the circuit 3 reads the operation date out of the E<2>PROM 2 and updates only the corresponding operation data when the signals 110-150 are supplied. Thus the circuit 3 switches the ON states of LED 41-43 and also changes the display value of an LED 44. Furthermore the circuit 3 stores only the updated operation data in the E<2>PROM 2 when a prescribed time passed after the input of ON signals are discontinued.

IPC: B65H29/60
Filed: 1987-11-26
Abstract: PURPOSE:To prevent the contamination of a pressure roller by changing a direct sheet ejecting path in the downstream side of a pressure roller and of a conveying roller which rotates in synchronization in contact with the pressure roller to a sheet conveying path between the pressure roller and the conveying roller. CONSTITUTION:In the case of a single-sided copying mode, a part of toner which is transferred to a transfer sheet is stuck to a heat roller 27 and the toner is transferred to the pressure roller 28 after passing of transfer sheet. The passed transfer sheet is guided to switching boards 47a and 47b and ejected by an ejecting roller 48. In the case of a double-sided copying mode, when the transfer sheet is conveyed by the rollers 27 and 28, it is guided to the switching boards 47a and 47b, and is conveyed to an inversion path 46 temporarily. Then the transfer sheet is conveyed downward again by rollers 55a and 55b, and is guided to a return path 49. In this case, since the transfer sheet passes between the roller 28 and the conveying roller 60, reverse feeding is performed in the condition that toner-image-transferred-sided surface comes into contact with the roller 28. Thus the toner sticking to the roller 28 is attracted to the toner on the transfer sheet, and the sticking toner is removed by the roller 28.

Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent illegal use and to keep privacy by controlling a certifying number transmitted and received between slave and master sets based on control information. SOLUTION: A master set data processing part 16 constructs a data string to send for requiring link establishment to the slave set 1.
