Title: Control unit for regeneration and power running of dc motor
Inventor: FUJITA KATSUHISA
IPC: B60L15/28
Filed: 1986-04-17
Abstract: PURPOSE:To shorten the time lag before a DC motor gets to regeneration or power running control, by pulling a bypass conductor apart and immediately executing the regenerative braking without processing discrimination when the bypass conductor is judged to be closed. CONSTITUTION:A CPU judges whether or not a bypass conductor 16 is closed immediately before the change-over when a forward and backward lever 25 is changed over. In case the bypass conductor 16 is closed, a processing action is taken at once to apply the regenerative braking. In case the bypass conductor 16 is opened, a processing action to discriminate is taken whether or not the regenerative braking is allowed. When it is judged that the regenerative braking can be applied, the power running is performed after the regenerative braking is applied. On the other hand, when it is judged that the regenerative braking cannot be applied, the power running is done immediately without regenerative braking.

Filed: 1988-04-14
Abstract: PURPOSE:To lower stress generated by bending in fin sections and to prevent the spreading of sections among the fins and the crack of a resin mold package by projecting the tabular fins from the resin package for a resin seal type semiconductor device and forming through-holes in the direction of the plate thickness of the projecting sections from the package of the fins. CONSTITUTION:Slots 11a are shaped to fins 11 projected from a resin mold package 101 for a semiconductor device, and the size of the slots 11a is set by the width and plate thickness of the fins 11. Approximately half the width of the fins 11 is excellent in thermal conductivity and strength and the like. In a lead frame 12 for an IC in which the semiconductor device is assembled, the fins 11 are shaped previously at the same time as the punching of the lead frame to projecting sections from the mold package 101. Since the slots 11a are formed to the fins 11, stress by bending is lowered, the generation of cracks in the package 101 and the spreading of sections among the fins are prevented, and quality is stabilized.
