Title: Surge absorber unit for electronic equipment
Inventor: SHIRAI KENKO
IPC: H02H9/04
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To effectively protect electronic equipment from lightning voltages. SOLUTION: Arresters Ai (i=1, 2,...) are respectively interposed between line-side terminals L1 and L2 and a grounding terminal E and between the terminals L1 and L2 and pulse resistance elements PR1 and PR2 are respectively interposed between the corresponding line-side terminals L1 and L2 and equipment-side terminals T1 and T2. The resistance elements PR1 and PR2 exhibit a sufficiently large lightning voltage suppressing performance as a whole by absorbing a steep pulse-like initial surface voltage which is caused by the discharge delay time of the arresters Ai as a resistance loss caused by a core loss.

Title: Insulator device
Inventor: ITO SUSUMU
IPC: H01B17/42
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To provide an insulator device that allows using a small shield ring whether the shield ring is used or not.

Filed: 1991-09-13
Abstract: PURPOSE:To reduce vibrations and noises accompanying surge pressure without degrading a responsive property by providing a controller for controlling the operation of an auxiliary valve on the basis of the detecting result of a pressure sensor when a return liquid path is shut off by a pressure control valve. CONSTITUTION:When a pressure control valve 13 shuts off a return liquid path 16, a pressure sensor 26 detects pressure in the return liquid path 16. When the pressure is lower than a predetermined value, an auxiliary value controller 25 drives a valve element 21 of an auxiliary valve 19 in the direction of reducing the sectional area of the return liquid path 16. Thus, the flow resistance of the return liquid path 16 is increased and liquid in the return liquid path 16 is prevented from flowing toward a reservoir 17 to prevent the generation of liquid column separation, so that vibrations and noises accompanying surge pressure generated by the reunion of the liquid column separation can be reduced.

Title: Positonal information checking system
Inventor: HORIE HIDEO
IPC: G11B15/087
Filed: 1982-12-25
Abstract: PURPOSE:To reduce a time necessary for stepping and to obtain efficiently accurate positional information by using positional signal information recorded just before a data area basically for positional deviation check. CONSTITUTION:A revolving magnetic head runs from lower left to upper right in a magnetic tape 1. When writing and reading of data for n-th track T is completed, the magnetic tape 1 is stepped so that (n+1)-th track T is positioned below the head. The head passes the zone of positional signal information S1 and S2, and detects the position of the magnetic tape at that time. The device can be so constituted that positional deviation at the time of reading positional signal information S2 is always smaller than positional deviation at the time of reading positional signal information S1. In this case, a device with better efficiency can be obtained by using the positional signal information S2 as position check information. However, when the accuracy of positional signal information S2 is insufficient, the positional signal information S1 is used for position check information.
