Title: Reamer bolt extracting device
Inventor: IWASE HIROO
IPC: B23P19/06
Filed: 1987-07-15
Abstract: PURPOSE:To enable a reamer bolt to be extracted quickly, easily and without any possibility of damaging it by shrinking the reamer bolt thermically by means of supplying low temperature fluid to circulate through a cooling hole provided along the center line of the reamer bolt. CONSTITUTION:A cooling hole 9 is drilled on a reamer bolt 5 along its center line. Liquid nitrogen 10 is introduced to a manifold 18 through a diaphragm valve 12 while compressed air 11 is introduced to the manifold 18 through a diaphragm valve 22 and the mixed gas is introduced into the cooling hole 9. The mixing ratio is regulated by controlling the diaphragm valve 22 with an air transmitter 21 based on signals from thermocouples 19, 13 and the established value becomes the temperature difference between the reamer bolt 5 and the mixed gas detected by a temperature difference detector 20. As a result of comparison of the signals of thermocouples 14, 13 with a temperature difference detector 15, a signal 17 actuates to close the diaphragm valves 12, 22 with an air transmitter 16 when the temperature difference reaches the value which causes the fitting of the reamer bolt 5 to become loose.

Title: Switching power-supply circuit
Inventor: SHINADA YOSUKE
IPC: H02M3/28
Filed: 1994-07-27
Abstract: PURPOSE:To obtain a switching power-supply circuit in which a loss caused by the operating delay of a MOS5ET for synchronous rectification with reference to the operation of a main switch is reduced to a minimum under various input conditions and various load conditions in a switching power supply which uses the MOSFET for a rectifying operation. CONSTITUTION:Control-signal levels V0 to V2 which correspond to an output voltage generated by a control circuit 26 and triangular waves V3 are level- compared by respective comparators 19 to 22, and respective switching elements 3 to 5 are ON-OFF-controlled by using respective comparison output pulses P0 to P2.At this time, the control-signal level V1 is level-shifted sequentially by constant values (VCE,1, VCE2) by means of transistors 12, 13 in a saturated state, and the control-signal levels V0, V2 are generated. Since the control-signal levels V0, V2 are level-shifted by the constant values with reference to the control-signal level 1, the dead time in an ON-OFF-operation of the switching elements 3, 4, 5 can be maintained constant irrespective of an input/output condition.

Title: Lead frame for semiconductor device and manufacture thereof
Inventor: MARUMO SHUICHI
IPC: H01L23/50
Filed: 1992-07-03
Abstract: PURPOSE:To prevent coming-off of a lead electrode from a resin mold by forming at least one hole part near a stitch bond of a lead frame by etching or press. CONSTITUTION:Heat stress causes by a difference in the thermal expansion at the time of mounting a substrate causes coming-off between the surface of a lead electrode 4 and a resin mold. Coming-off causes when force works in the A-A' plane in the direction parallel to A-A', however, when a hole part 7 is provided near a stitch bond 6, resin enters inside the hole part for being solidified so as to heighten close adhesiveness between the lead electrode surface and the resin surface. Thereby, coming-off of the lead electrode 4 from the resin surface can be prevented while preventing breaking of the stitch bond 6.
