Abstract: PURPOSE: To increase the impedance between a low voltage winding and other windings while reducing the range of changes due to the tapping of the impedance between high and medium voltage windings by winding a side leg of a core with a tap winding while a side leg is wound with the low voltage winding.  
     CONSTITUTION: Main legs 5A and 5B and a side leg 5C are provided on a core and high voltage winding units 1A and 1B are provided on the main legs 5A and 5B respectively. One main leg 1A of the core is wound with a line side medium winding unit 12A and the other main leg 1B of the core is wound with a neutral side medium voltage winding unit 12B, which is connected to the winding unit 12A. The side leg 5C of the core is wound with a tapping winding and then, a low potential winding 3 while it is connected in parallel with an excitation winding 3C. This relatively facilitates the work of super high voltage winding while reducing the range of changes in the impedance between the high and medium windings. The impedance can be increased significantly between the low voltage winding and other windings.

Title: Injection molder
Inventor: SONODA YUBUN
IPC: B29C45/50
Filed: 1987-05-20
Abstract: PURPOSE:To reduce the damage of fibers added to molding material by a structure wherein a screw, which develops pressure necessary for feeding the molding material forwards, is provided at a region for supplying the molding material and the tip side beyond the screw is turned to be a plunger. CONSTITUTION:A rotary sliding member 7 is insertingly arranged in a barrel 6. In addition, a piston 8 is provided so as to externally fit to the rotary sliding member 7 and at the same time to internally fit to the barrel 6. Further, the section of the supplying region for supplying molding material of the rotary sliding member 7 is turned to be a screw shaft 11. The sections of the compressing and metering regions located at the tip side beyond said supplying region is turned to be a plunger 12. In other words, the rotary sliding member 7 has a so-called rotary screw and plunger structure. Though the molding material is subjected to shearing action at the supplying region by the groove of the screw shaft 11, almost no fiber added to the molding material is damaged, since the molding material in the section is solid. Furthermore, since the member has the plunger structure in the melting and metering regions, the damage of the fiber is extremely small and consequently the fiber can give enough reinforcing effect to the molding material.

Title: Multilayer printed wiring board
Inventor: FUKUKAWA HIROSHI
IPC: H05K3/46
Filed: 1995-04-25
Abstract: PURPOSE: To control the thickness between insulating layers with high accuracy and thereby increase reliability by forming the resin insulating layer in a reversed pattern to an inner-layer circuit pattern and thereby flattening the surface of an inner-layer circuit board. CONSTITUTION: On both faces of an inner-layer circuit board 3, inner-layer circuits 5 are preliminarily formed. Then, resin insulating layers in a reversed pattern to that of the inner- layer circuits are formed by screen printing or another method on the entire surface of the inner-layer circuit board 3 except for a part where the inner-layer circuits 5 are formed. Between a plurality of the inner-layer circuit boards 3 on which the resin insulating layers 2 are formed or in the most outer layers, prepregs 4 are located. Then, copper foils 1 are stacked on both faces of the stacked body and then the stacked body is heated and pressed to be formed into an integral body. A multilayer printed wiring board is thus manufactured.  By forming the resin insulating layers 2 in a reversed pattern to that of the inner-layer circuits on the entire surface of the inner-layer circuit board except for a part where inner- layer circuits are formed, the surface of the inner-layer circuit board 3 can be flattened. A resin component which constitutes the thickness of the insulating layer is not influenced by the inner-layer circuit density and is not limited by routing of inner-layer circuits. Therefore, an accuracy of the thickness between the insulating layers is increased and thereby the reliability can be increased, too.

Title: Three-phase polarized-wave reluctance motor
Inventor: BAN ITSUKI
IPC: H02P6/16
Filed: 1989-05-19
Abstract: PURPOSE:To prevent the generation of a negative torque by energizing respective exciting coils cyclically through energizing first - third phase exciting coils over the width at intervals of electrical angles of 120 degrees. CONSTITUTION:When exciting coils L(17b, 17e) are energized, salient poles 1b, 1f are attached, so that a rotor 1 rotates in the direction of the arrow A. When said rotor rotates by 90 degrees, the energization of said exciting coils L is cut OFF and exciting coils M(17c, 17f) are energized. When the rotor further turns by 120 degrees, the energization of said exciting coils M is interrupted and exciting coils K(17a, 17d) are energized. Then, said exciting coils K, L, and M cyclically alternate with each other in said order in the energization mode for every rotation of 120 degrees so that the title apparatus is driven as a three-phase polarized-wave motor. In this case, magnetic poles (16a, 16d), (16b, 16e), and (16c, 16f) positioned symmetrically with respect to the axis 5 are magnetized into N and S poles, respectively. Therefore, leakage fluxes passing through non-excitation poles are directed oppositely to each other. Thus, it is possible to prevent the generation of a negative torque.
