Title: Lead frame for semiconductor device
Inventor: SUGIO TOSHIHIKO
IPC: H01L23/48
Filed: 1988-05-24
Abstract: PURPOSE:To improve the yield of the external appearances in soldering, by providing a plurality of suspending leads for suspension from the upper part on a common frame. CONSTITUTION:Suspending leads 4 are provided on a common frame 2. Therefore, chucks and hangers are not used when electronic parts are lifted for solder dipping. In this way, the solder dipping can be performed without touching to a packages 6 and leads 1. Since pressure is not applied to the package 6, it is not deformed at all. Even if solder is splashed, the solder is solidified intactly. Therefore, when electronic parts are suspended and their leads undergo solder dipping, the electronic parts are not dropped, the shapes of the packages 6 are not deformed and the parts can be fixed to the package 6 having any shape. In this way, the solder dipping depth becomes uniform, and the yield of the external appearances in soldering is improved.

Title: Pump fitted with motor suppressing increase of thrust
Inventor: KUBOTA KOJI
IPC: H02K5/132
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a canned motor pump which is of pressurized circulation, equipped with an opposed-type multistage impeller for suppressing the axial thrust, even at starting or stoppage and preventing boiling of liquid handled. SOLUTION: Thrust from the other impeller chamber 12 to one impeller chamber 10 acts on a rotary shaft 16. The thrust becomes large, when the flow rate of the liquid flowing from the other impeller chamber 12 to one impeller chamber 10 through space between bearings 18 and 20 and the rotary shaft 16, and the space between a rotor 22a and a stay 22b becomes large and the thrust becomes small, when the flow rate is small. So, since the inner circulation flow becomes small by a throttle mechanism 26, the thrust becomes small. Moreover, since the liquid pressure becomes high in the bearings 18 and 20 lying in front of (upstream of) the throttling mechanism 26, this motor pump can prevent boiling of the handling liquid for the canned motor pump 1, in the bearings 18 and 20.
