IPC: H02M7/155
Filed: 1978-11-14
Abstract: PURPOSE: To reduce reactive power and harmonic currents by combining a converter which is asymmetrically controlled within the range wherein a power factor is delayed from an AC power supply system and a converter which is asymmetrically controlled within the range wherein the power factor is gained.  
     CONSTITUTION: An AC power supply system 1 is connected to a power converter which comprises a bridge-type converter 31 which is constituted as a separately excited converter and is asymmetrically controlled within the range wherein power factor delays and a bridge-type converter 32 which is constituted as a self-excited converter and is asymmetrically controlled within the range wherein power factor gains, and supplies power to loads 41 and 42. The asymmetrical control is performed by triggering and controlling a pair of thyristors on one side at a fixed control angle and by controlling the other pair of thyristors at variable control angles in response to the load requirements. In this constitution, harmonic currents which are generated in the AC-power supply system can be greatly reduced without sacrificing the reduction effect of reactive power which is derived from the AC power supply system.

Filed: 1990-05-30
Abstract: PURPOSE:To positively lower the temperature of a bearing pat by discharging air from a motor chamber with the use of a vacuum which can be induced by an air steam produced in association with the rotation of fan blades. CONSTITUTION:When an armature in a motor chamber R is rotated, a gap G as a vacuum generating passage is created being communicated with a flow passage for an air stream flowing along an armature frame 20 and the outer peripheral surface of a stator frame 301. Further, through-holes 16, 18 for communicating the inside of the motor chamber R with the atmosphere are formed in the bottom wall part 20a of the armature frame 20. In this arrangement, the opening area of the gap G on the air steam side is set so as to generate an air stream which can positive lower the temperature of a bearing box 304, within the motor chamber R. Since air can be discharged from the motor chamber R with the use of vacuum induced by the air stream generated in association with the rotation of fan blades 19, it is possible to positively lower the temperature of the journal box 304.

Title: Quilting cloth
Inventor: KUBOTA SHIGEKO
IPC: B68G7/08
Filed: 1988-06-08
Abstract: PURPOSE:To obtain the satisfactory shape-keeping of a rugged shape and soft feeling by using surface cloth, internal cotton and thermal contractive base cloth as lining cloth, executing heat treatment after sewing and uniting the cloth and cotton and contracting the thermal contractive base cloth. CONSTITUTION:For such quilting cloth, the thermal contractive base cloth is used as the lining cloth and the internal cotton is sandwiched between the surface cloth and lining cloth. After that, the cloth and cotton are sewed and united and next, the heat treatment is executed. Then, the thermal contractive base cloth execites thermal contraction. By this thermal contraction of the thermal contractive base cloth, the rugged shape of surface cloth goes to be more obvious and the internal cotton is pushed-up in the direction of the surface cloth. Then, since the internal cotton is charged in the projecting part of the surface cloth, the quilting cloth is restored to an original shape even when it is pressed. As the thermal contractive base cloth, for example, woven fabric or non-woven fabric to include thermal contractive fiber are enumerated. Among examples, the non-woven fabric is preferable since the falling of cotton is hardly generated in comparison with the knitting and woven fabric and the including quantity of the thermal contractive fiber can be freely set.
