Title: Emc test site used both as total reflection type and antireflection type
Inventor: SHIBUYA MOICHI
IPC: G01R29/08
Filed: 1993-08-08
Abstract: PURPOSE:To realize a low-cost EMC(electromagnetic-compatibility) test site which is easily converted between a 'total reflection type' and an 'antireflection type'. CONSTITUTION:Floor units 3 whose surface has been formed of a metal plane 1 and in which a microwave absorber 2 has been attached and installed in a part or the whole of the rear are spread and arranged in such a way that their surface is faced upward, a 'total reflection type' is constituted, the same floor units 3 are arranged in such a way that they are erected in a fence shape directly at the lower part of a wave passage, and an 'antireflection type' is constituted. Consequently, it is possible to obtain a site in which the 'total reflection type' and the 'antireflection type' can be converted easily into each other. Since no interference disturbance due to two-time reflection between parallel fences is caused, it is possible to obtain the sufficient suppression effect of reflected waves by a low fence. It is possible to prevent performance from being degraded due to the proximity coupling of the fence to an antenna 7. The cost of an installation is lowered, and the reproducibility of electric performance due to the conversion of the types becomes good.

Title: Tracking mechanism of magnetic recorder
Inventor: KAWAHIRA MASAYOSHI
IPC: G11B5/54
Filed: 1983-12-07
Abstract: PURPOSE:To always designate accurately a track by attaching removably a pad supporter fixing a pad to an attachment plate and therefore exchanging pads according to the wear and in an extremely easy way. CONSTITUTION:A felt 13 serving as a soft pad containing oil is adhered to a pad supporter 12 having a screw hole 14. The supporter 12 can be attached removably to an attachment plate 10 by screwing a screw 16 inserted to an attachment hole 15 of the plate 10 into the hole 14. The felt 13 is worn and deformed with long-period use owing to the pressure-contact force to a screw 4 or the oil contained in the felt 13. In such a case, the screw 16 is unfastened to replace the felt 13 together with the supporter 12. Thus it is possible to set a hook element 9 into the groove of the screw 4 without any play. Thus a head base 5 can be moved with an accurate degree of shift in proportion to the revolving angle of the screw 4. This ensures the accurate designation of tracks of a magnetic tape 2 for a long period of time.
