Patent JP-H02292767-A (JP)
Title: Magnetic recording and reproducing device
Inventor: OHARA TAKAAKI
IPC: G11B15/00
Filed: 1989-04-29
Abstract: PURPOSE:To switch the traveling direction of a tape while maintaining the appropriate tension of the tape by releasing the energizing force of a spring for a brake releasing lever by a control plate and pressing the releasing lever so that it may be forcibly turned in a brake releasing direction. CONSTITUTION:At the time of switching the traveling in a normal direction of the tape to the traveling in a reverse direction, the 1st abutting piece 25 of the control plate 2 acts to the brake releasing spring 43 to release the energizing force of the spring 43 for the releasing lever 42. Then, a 2nd abutting piece 26 presses the brake releasing lever 42 to forcibly turn the releasing lever 42 in the brake releasing direction. By operating the control plate 2 while forcibly turning the lever 42, a back tension energizing force reducing spring 73 is allowed to act to a back tension lever 31 so as to reduce the tensile force of the back tension lever to the tape. Thus, the spring force of the tension lever is reduced and the optimum tension is added to the tape. In such a state, the traveling direction of the tape is switched.

Title: Magnetic head
Inventor: MORIOKA YOSHIHIRO
IPC: G11B5/187
Filed: 1987-05-07
Abstract: PURPOSE:To reduce the crosstalk disturbance by changing the effective track width depending on the signal frequency to be recorded while effectively utilizing the recording enable area on the surface of the magnetic tape. CONSTITUTION:The type of material or the shape of the magnetic head is selected so that the magnetic reluctance of both ends 4, 5 of the track of the magnetic head 1 near a gap 2 is increased inversely proportional to the frequency and the change in the magnetic reluctance at the track edge is more eminent than that at the center of track. When the magnetic reluctance is change in this way, the more frequency is increased the more effective track width of the magnetic head 1 is increased. Thus, the magnitude of the crosstalk disturbance from adjacent tracks is decreased and the S/N of the signal reproduced by the magnetic head 1 is remarkably improved.

Title: Shock absorber for leaping up of marine propulsion machine
Inventor: SAITO HIDEKI
IPC: B63H20/08
Filed: 1988-05-10
Abstract: PURPOSE:To make it possible to absorb shock toward a propulsion unit without giving heavy stress to the propulsion unit by providing a means to throttle the area of a passage in a cylinder at the same timing as the lower part of the propulsion unit leaps up to attain the surface of the water. CONSTITUTION:When an under water obstacle collides against a lower part of a propulsion unit to compress a hydraulic oil in the first chamber 19 of a cylinder 18 above a fixed pressure, an absorber valve 35 opens to make the propulsion unit leap up. In this case, damping force based on the valve opening pressure of the absorber valve 35 and the passage resistance force of the first passage 101 provided with the valve 35 is strong at the time of collision occurring at the highest travelling speed of a piston rod 17 as shown by a broken line A, and then decreases as the travelling speed of the piston rod 17 slows down. When the lower part of the propulsion unit attains the surface of the water, a throttle valve 40 throttles the area of the first passage 101, and the damping force therefore rapidly grows larger according to throttle resisting force caused by the throttling of the valve 40 as shown by a broken line B, and then decreases again.
