Abstract: PURPOSE:To detect assuredly a non-signal part between recorded parts with a intermusic space detecting circuit even by a tape which is recorded by using different types of noise reducing circuits, by switching the threshold detecting level of the intermusic space detecting circuit in interlocking with the selection of the noise reducing circuit. CONSTITUTION:An intermusic space detecting circuit 6 contains a level detector and can vary the threshold value which decides the detecting level by changing the reference value of the DC voltage from outside. The reference value of the DC voltage is obtained from the voltage generated across a resistance by flowing the constant current supplied from a constant current output terminal 6b of the circuit 6 to the resistance. Thus the threshold value is obtained bust by changing the value of the resistance. An NR selection switch S2 interlocks with a threshold value setting switch S1. The output selected by the switch S2 is amplified by an output amplifier 5 and supplied to an output terminal 8. The output fed from an output terminal 6d of the circuit 6 controls a tape driving controller 7.

Abstract: PURPOSE:To make a highly hard metallic compd. layer having good adhesion on the surface of a tip and to obtain a sintered hard alloy cutting tool having a long life, by growing a thin film on the tip by vacuum deposition, and irradiating an ion beam from an ion source thereby implanting ions to the film. CONSTITUTION:A film forming material is vapor-deposited on a cutting tool as a target (g) from a vapor deposition source. The ions formed in an ion source (a) at the same instant are passed successively through a mass analysis system (b) and an acceleration system (c) and are thus accelerated to the ions having required kinetic energy and mass, whereafter the ions are adjusted to form an ion beam spot of the diameter conforming to the size of the target with a focusing system (d). The spot is deflected with a deflection system (e) and is irradiated to the target. The implanted layer wherein the atoms of the tool (g) and the thin film exist as a mixture is thus formed and if the material of the thin film is suitably selected, the hard layer consisting of the implanted layer differing from the tool forming material is formed.
