Title: Multilayer wiring board having metal core
Inventor: HIGUCHI KAZUAKI
IPC: H05K1/02
Filed: 1990-03-12
Abstract: PURPOSE:To realize high density mounting of elements by alternately bonding and laminating insulating layers and wiring layers on a basic member composed of a metal having high heat conductivity, fusing the solder arranged between the wiring layers at a temperature higher than the fusing temperature of the solder for mounting the elements thereby connecting the wiring layers. CONSTITUTION:Insulating layers 2 and wiring layers 3a-3c are bonded and laminated alternately on a metallic base member 5 having high heat conductivity and solder is placed between the wiring layers 3a-3c. The solder is then fused with a temperature higher than the fusing temperature of the solder for mounting elements 8, 9 thus connecting the wiring layers 3a-3c. Since the metallic base member 5 having high heat conductivity is employed, majority of heat produced from the elements 8, 9 mounted in high density is dissipated through the metal core of the base member 5. Consequently, the elements can be mounted with high density even when they can not be cooled forcibly.

Filed: 1983-04-08
Abstract: PURPOSE:To enable to obtain high positioning accuracy of a DC motor by absorbing a counterelectromotive force generated from the motor at the stopping time of the motor through a bridge rectifier to a semiconductor switching element. CONSTITUTION:In order to abruptly stop a motor M, when a command signal Vs is rapidly set to a zero level, a counterelectromotive force is generated from the drive terminal of the motor M. Since a transistor Q1 becomes conductive state by setting the signal Vs to the zero level, the counterelectromotive force generated from the motor M is flowed through a bridge circuit BD1 to the transistor Q1. In this manner, the motor M is immediately regeneratively braked by an active load via the transistor Q1 and instantaneously stopped.
