Title: Magnetic tape head
Inventor: ODA HIROYASU
IPC: G11B5/725
Filed: 1986-09-09
Abstract: PURPOSE:To supply an adequate amt. of lubricating agent to a tape traveling surface and to smooth the sliding of a magnetic tape by providing such a porous part into which the lubricating agent can be impregnated to the tape traveling surface of a magnetic tape head and impregnating the lubricating agent into the porous part. CONSTITUTION:The porous part 11 is provided in the region including at least the region near a gap G on a core material 4 of the magnetic tape head and the surface thereof serves as the magnetic tape traveling surface 12. The lubricating agent is impregnated into the porous part 11. The lubricating agent bleeds little by little from the inside of the porous part 11 onto the surface 12 to replenish the lubricating agent as the lubricating agent on the magnetic tape head surfaces consumed. Since just a small amt. of the lubricating agent exists on the surface 12, the oversticking of the lubricating agent to the magnetic tape and the generation of sticking are obviated and since the lubricating agent impregnated in the porous part 11 bleeds just slightly, the lubricating agent lasts long in the porous part 11 and the lubricating effect is maintained for a long period.

IPC: H01J23/14
Filed: 1986-09-09
Abstract: PURPOSE:To prevent the short circuit between a shield cap and a side pin by providing a shield section made by coupling the shield cap and a choke seramic together. CONSTITUTION:A shield section coupled with a shield cap having a lug 12 for coupling with a choke ceramic 9 is provided. The shield cap is coupled via its lug 12.

Filed: 1993-08-05
Abstract: PURPOSE:To reduce the memory capacity required for display of the let-off amount of a fishing line of a reel for fishing and to display the let-off amount in detail. CONSTITUTION:The respective amounts of wound fishing line corresponding to each standard unit of the rotational amount of a spool (e.g. each five time output of detection signal) are measured from the state in which the fishing line is not wound around the spool and the measured values are stored in order. In practical fishing, the measured value corresponding to the standard unit of the rotational amount is read out each time the rotational amount of the spool reaches the standard unit of the rotational amount. The measured values read out according to the rotational direction of the spool are added or reduced so as to calculate the total length of the fishing line and the calculated value is shown on a display. In addition, the length of the fishing line corresponding to the unit rotational amount of the spool (one rotation) is calculated based on the length of the fishing line every standard unit of the rotational amount. According to the resultant calculated result, the length of the fishing line corresponding to the actual rotational amount of the spool is calculated and displayed.
