Title: Rear suspension damping device and freight vehicle
Inventor: MA LIBIN
IPC: B60G11/00
Filed: 2017-11-29
Abstract: The present invention relates to the technical field of freight vehicle manufacturing, and particularly to a rear suspension damping device and a freight vehicle. The rear suspension damping device includes steel plate spring seats, a vehicle frame, a rear axle and dampers. The steel plate spring seats are mounted on left and right sides of the rear axle, and the steel plate spring seat located on each of the sides is connected thereon with a lower damper pin shaft, each of a left longitudinal beam and a right longitudinal beam of the vehicle frame is connected with an upper damper pin shaft, and the dampers are connected between the lower damper pin shaft and the upper damper pin shaft located at a same side, respectively. Different from the prior art, there is no need to additionally weld two lower damper brackets on an axle housing of the rear axle, and therefore, the manufacturing process is relatively simple and the production cost is relatively low. Besides, since the damper located on the left side is mounted behind the rear axle and thus would not interfere with a part such as a load sensing pressure proportioning valve of a hydraulic braking system, such rear suspension damping device can be widely used in light freight vehicles.

Title: Lead frame, manufacture thereof, and semiconductor device
Inventor: KUSUKAWA JUNPEI
IPC: H01L23/50
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To enhance the adjacent inner leads of a lead frame in insulating reliability between them. SOLUTION: An adhesive agent layer 2 which bonds inner leads 1 to an insulating sheet 3 is formed smaller in width than the inner lead 1 in a direction vertical to the longer direction of the inner lead 1. When the adhesive agent layer 2 is provided as mentioned above, no adhesive agent layer is present between the adjacent inner leads 1, so that metal material dissolved in the adhesive agent layer is prevented from causing a short circuit between the adjacent inner leads 1 even if metal material is dissolved into the adhesive agent layer 2. Therefore, adjacent inner leads can be kept high in electrical insulation properties between them.
