With this arrangement, it is possible to fix the shielding case and the adjusting plate. Thus it is possible to fix the shielding case to the adjusting plate without using screws, and can be decreases costs of parts and manufacture.

Abstract: An audio/control head for used in a Video Cassette Recorder or the like has a core holder 11 arranged to include positioning portions 24 and 25 for determining the pitch length P1 and pressing tabs 23 having an elasticity for pressing inwardly cores members 15 and 17 against the positioning portions 24 and 25 from the outer side. As the cores members 15 and 17 are held directly on the positioning portions 24 and 25, they are inwardly pressed by the pressing tabs 23. Then, the core pitch p1 is precisely determined between the audio core and the control core without using particular jig during the assembly. The overall number of jigs required for mounting the cores to the core holder cab be reduced. Also, the core pitch P1 can be improved in the accuracy and the characteristics of the head will be consistent.

Abstract: The speaker recognition methods and systems of the current invention involves at least two processing units for performing the speaker recognition based upon his or her voice input. To perform the speaker recognition efficiently as well as securely, the voice input is initially processed at the input site so that intermediate voice characteristic information is extracted. The intermediate voice characteristic information is transmitted to a second location for the final determination for identifying or verifying a speaker.

Abstract: A network interface unit couples a lattice communication network and at least one token ring network. The network interface unit includes a sequence controller which controls a token detector and a reception register so that message information received from the lattice communication network via a node apparatus connection port is looped back from the token ring network via a terminal connection port and output from the node apparatus connection port when an address detector detects that a destination address matches a stored source address, and absorbed when the address detector detects that the destination address does not match the stored source address.

Abstract: An ion implantation apparatus which is suited for manufacturing semiconductor devices and which is particularly suited for implanting double charged ions into the wafers 22. Ions of a predetermined mass only are selected by a mass-separating electromagnet 14 from an ion beam 12 that is emitted from an ion source 10, and are implanted into the wafer 22 via a slit 16. Between the slit 16 and the mass-separating electromagnet, there are provided field electrodes 24 having a direction of deflection which is the same as that of the mass-separating electromagnet 14 to separate ions having different energy levels, and deflection magnets 26 having a direction of deflection at right angles with the direction of deflection of the mass-separating electromagnet. The slit 16 is arranged so that undeflected neutral particles and low energy ions deflected by the field electrodes 24 will pass through the slit while high energy ions will be deflected the proper amount to pass through the slit.

Abstract: In an ion implantation system wherein an ion beam is scanned by deflection means in a predetermined direction on substrates placed on a disc rotating at a constant speed, to implant the substrates with ions; ion beam detectors are arranged in correspondence with a plurality of places of the substrate before the ion implantation. When the ion beam is scanned, sums of outputs of the respective ion beam detectors in the plurality of scanning positions are evaluated, and correction operations are executed so that they may become constant values. The scanning rate of the ion beam by the deflection means is controlled according to the corrections. Thus, when the ion beam is actually implanted into the substrate, the density of the ion beam becomes uniform.
