  • Patent number: 11967862
    Abstract: In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

  • Patent number: 11955359
    Abstract: The present disclosure provides a magazine supporting equipment for supporting a magazine with multiple input ports. The magazine supporting equipment comprises a contact plate, a first sidewall plate, and a second sidewall plate. The contact plate is in contact with the magazine. The first sidewall plate extends vertically from one end of the contact plate. The second sidewall plate parallel is to the first sidewall plate and extends vertically from one end to the other end of the contact plate. The first sidewall plate extends along at least a part of a first sidewall of the magazine. The second sidewall plate extends along at least a part of a second sidewall of the magazine. The first sidewall plate and the second sidewall plate include control openings through which gas flows in and out.

  • Patent number: 8365321
    Abstract: A method of manufacturing a bathtub includes a first operation of forming an external structure layer forming an external appearance of the bathtub; a second operation of forming a mold-release agent layer having a bathtub forming surface corresponding to an internal shape of the bathtub and a flange extending from a circumference of the bathtub forming surface to the outside, on an external surface of an internal mold; and a third operation of forming a semi-rigid foam layer having a first unfoaming painted layer, a soft foam layer, and a second unfoaming painted layer in sequence such that the soft foam layer is sandwiched between the first unfoaming painted layer and the second unfoaming painted layer. The semi-rigid foam layer is formed between the external structure layer and the mold-release agent layer by being injected in a space between the external structure layer and the mold-release agent layer.
