    摘要: A magnetic head using an MR element and a permanent magnet for applying a bias magnetic field to the MR element, and a lead frame of the head. A sheet of metal is punched or otherwise shaped in a predetermined pattern to produce the lead frame. The lead frame includes sections mounting the MR element and permanent magnet, lead connecting sections electrically connected to connecting sections of the MR element, and tape-contact sections which are flush with a tape-contact surface of the MR element. The lead frame mounted with the MR element and permanent magnet and provided with the lead connecting sections is placed in a metal mold having a predetermined configuration and buried and fixed in place in synthetic resin.

    摘要: A termination circuit to reduce the overshoot and undershoot that are generated when switching the voltage level of a transmission line. The terminating circuit (11) has a termination switching circuit (40) and an auxiliary switching circuit (41). When the voltage level of the termination (5) of the transmission line (4) is switched from a low level to a high level, the termination switching circuit (40) switches the termination (5) that is connected to the ground potential at a low level to the power supply voltage (Vcc) corresponding to a high level, but before that connection is completed, due to the fact that the auxiliary switching circuit (41) temporarily connects the termination (5) to the ground potential corresponding to a low level, the impedance of the terminating circuit (11) is temporarily lowered. Therefore, the overshoot and the undershoot that were generated in the past when switching the voltage level can be reduced.

    摘要: This slider assembly has a stopper of one-piece structure that prevents the slider from coming off the rail member and which can easily be attached to and removed from the rail member and be manufactured at low cost. The slider of the slider assembly that can slide relative to the track rail is prevented by the stopper from coming off the track rail. The stopper comprises an embracing portion that embraces the slider on one side of the track rail and locking portions provided at both ends of the embracing portion. The embracing portion comprises a pair of leg portions and a bridge portion, and the locking portions each include a bent portion and a hook portion. The hook portions engage in the engagement portions as engagement holes formed in the track rail.

    摘要: An input circuit which prevents erroneous operation caused by noise. An input stage has a NMOS transistor N11 and a PMOS transistor P11. A NMOS transistor N12 is connected in series between a ground line and the source of the NMOS transistor N11. A PMOS transistor P12 coupled to a voltage supply line V.sub.cc acts as a current control element. NMOS transistors N13 and N14 are connected in series between the ground line and the drain of PMOS transistor P12. Inverters IV11 and IV12 delay the voltage of an intermediate output node S11 and supply it to the gate of NMOS transistor N13. The gate of NMOS transistor N12 is coupled to a node S13, the gate of NMOS transistor N14 is coupled to the input line for an input signal IN, and node S13 is formed to function as a voltage sensor with respect to the ground.
