Title: Switching power supply unit
Inventor: UTSUNO MIZUKI
IPC: H02M3/28
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To prevent a main transistor from being destroyed in a switching power supply unit, when the base current of the main transistor drops. SOLUTION: This switching power supply unit is provided with a pulse generator 30 for generating pulses for a DC voltage on/off switch (main transistor) 4.

Title: Reduced pressure casting method
Inventor: KUSUMI HARUO
IPC: B22C9/04
Filed: 1988-05-13
Abstract: PURPOSE:To reduce mixing ratio of residue of a lost foam pattern into molten metal and to improve the casting quality by forming the lost foam pattern to a hollow body and making space formed in sand mold by losing the lost foam pattern at the time of pouring molten metal more than the actual volume of the lost foam pattern. CONSTITUTION:The molten metal 13 is poured from a sprue 6 while making the sand mold part 5 under reduced pressure condition with degassing device 2. The molten metal 13 reaches to the lost foam pattern 3 while forming a runner by melting and evaporating a runner part 7, and the lost foam pattern 3 is melted, evaporated and lost. By losing the lost foam pattern 3, the molten metal is cast in the casting space formed in the sand mold part 5, that is, in the solid volume of the lost foam pattern 3 and the inner space. Then, as the casting space formed in the sand mold part 5 by losing the lost foam pattern 3 is formed with the lost foam pattern 3 having little solid volume and thin thickness, the residue quantity generated at the time of melting and evaporating the lost foam pattern 3 becomes a little quantity, the mixing ratio of the residue to the molten metal is reduced.

IPC: H02K23/02
Filed: 1987-05-15
Abstract: PURPOSE:To make an inexpensive enamel rectangular conductor available, by processing insulating resin adhesion to a field coil after a stator was assembled. CONSTITUTION:A field coil 14 is fixed into a pole core 10, which is then fitted to a yoke 1. The field coil 14 produces a clearance by the thickness of a binding tape 13 between the pole core 10 and the yoke 1. Then, the field coil 14 and pole core 10 are processed with insulating resin adhesion, such as powder insulating resin or insulating varnish. In this process an insulating film 15 is formed on the surface of a field coil 14, with which the exposed surface is covered and which fills up the clearance between the yoke 1 and pole core 10. Under this condition the bore diameters of each pole core 10 is finish-machined to the designated dimensions by machine-cutting. In this case, the field coil 14 is so firmly secured to the yoke 1 and the pole core 10 with the insulating film 15 that finish machining can be performed easily and the field coil 14 is prevented against chip adhesion that is left there. By finish machining the air gap will be uniform to each pole and the performance of field coils improved.
