Title: Leadframe and semiconductor device using the same
Inventor: NOUZUMI ATSUO
IPC: H01L23/50
Filed: 1991-06-11
Abstract: PURPOSE:To facilitate the mounting of components, and to reduce the size of the package by positioning a small-sized pad made of a dielectric tape on a predetermined location on either the top surface or the bottom surface of inner leads. CONSTITUTION:Small-sized square pads 5, which are made of a polyimide film and measure 2 by 2mm, are attached on inner leads 2. Using a strip-like material and a progressive metal mold, the inner leads 2, outer leads 3 and a die pad 4 are fabricated. A coining region is defined at one end of the inner leads 2 to ensure a flat width required for wire bonding. A plating layer of noble metal, such as Ag, is formed at the ends of both the inner leads and the die pad. In short, this leadframe is produced by fabricating the main body of the leadframe which has the inner leads 2, the outer leads 3 and the die pad 4, and then attaching the small-sized pads 5 to certain positions in accordance with a circuit configuration.

Abstract: PURPOSE:To shorten the time required for starting a sensorless and brushless motor. CONSTITUTION:A motor 11 has armature coils 11u, v, w and a rotor 11r, and the drive power supply of a battery 20 is applied via a switching device 21 to the armature coils 11u, v, w. By controlling signals SS1-SS6 fed from a drive controlling part 27, the switchovers of the ON-OFF states of switching elements S1-S6 are performed, and the rotational magnetic field generated by the armature coils is rotated. In the case of starting the motor 11, the switchovers of the excitation patterns of the armature coils are so performed at a long period during a predetermined time that the rotations of the magnetic field whose number is made not less than one are performed, and the direction of the rotational magnetic field of the armature coils is made to coincide with the one of the rotor 11r. Thereafter, the continuous switchover of the excitations of the armature coils are performed, and as a result, the starting term of the motor 11 can be shortened. When a load is coupled to the motor 11 via a unidirectional clutch mechanism as in the case of an electric vehicle, the switchovers of the excitations of the armature coils are so performed that the rotational magnetic field is first rotated slowly in the opposite direction to a light load and then is rotated in its positive direction.

Filed: 1981-09-09
Abstract: PURPOSE:To eliminate effectively an effect of the floating electrostatic capacity which enters equivalently the line connected to a constant current circuit via a switch circuit, by setting an electrostatic capacity circuit between the output terminal of the constant current circuit and a power supply or between the output terminal and an earth. CONSTITUTION:When a switch 21 is applied, an overcurrent flows to the floating capacity through an electrostatic capacity 4 which is newly provided. Thus the floating capacity is suddenly charged. Thus the potential VP of the switch 21 at the power supply side is set as VP=CN/(CN+CO)XVCC, where VCC, CN, CO and VP are a power supply, a capacity 41 newly provided, a floating electrostatic capacity and the voltage at a point P, respectively. As a result, the voltage VP can be set larger than the reference voltage VS even when a switch is applied. An effect of the floating capacity can be effectively prevented by setting the a capacity CN larger enough than the capacity CO.
