One ends of snubber resistances 7aN and 7bN are respectively connected to the connecting points of the intermediate potential point of a DC power source 1, namely, voltage dividing capacitors 3a and 3b and flywheel diodes 8a and 8b. While a transistor 4a is turned off, the voltage of a snubber capacitor 5a is discharged through the snubber resistance 7aN and an end-to-end voltage is maintained across the capacitor 5a. When the transistor 4a is turned on, the end-to-end voltage is maintained across the capacitor 5a, since the capacitor 5a cannot discharge. The same can be said to the negative group choppers 2B.

Title: Screw head of injection molder
Inventor: SUUMEN HIROYOSHI
IPC: B29C45/52
Filed: 1990-06-01
Abstract: PURPOSE:To improve the fatigue strength of a screw head, reduce the stress amplitude and consequently make thread stronger against torsional moment and tensile stress and prevent the thread or thread recess from breaking by a method wherein an axially extended hole is formed at the center of the thread and thread recess. CONSTITUTION:At the center of a screw head 1, a hole 11 extending between thread recess 1d and thread 1e is formed axially. As a result, the thread recess 1d and the thread 1e have annular section respectively. By making the cross-sectional area of the annular section equal to that of the thread recess of the conventional screw head 1, the compressive strengths of the thread recess 1d and of the thread 1e s made equal to those of the conventional ones. Further, the deformation of the thread recess is easy and its fatigue strength can be made equal to that of the conventional thread recess. Furthermore, the larger the outer diameter (d) of the thread recess 1d becomes and the smaller the the diameter (a) of the hole 11 of the thread recess 1d becomes, the amount of torsional deformation becomes smaller. As for tensile force, since the tensile force concerned does not reach the trouble-making level in ordinary use state or at sucking back, the possession of the same strength as that havinng at present is enough for the screw head concerned.
