摘要： PURPOSE:To reduce the vibration of a head driving means, to prevent a whole device from vibrating and simultaneously to make the device a thin structure in the storing device using a rotary disk and a head provided to confront to the surface. CONSTITUTION:By arranging a head 3, a head supporting means 4 and plural flat coils 6 on the same plane around a fixed shaft 30, radial force exerted on the fixed shaft 30 is cancelled and only moment is remained. A base 14 loading a spindle shaft 17 rotating the disk 1 and the fixed shaft 21 of the head driving means consisting of a magnet 5 and the coils 6 is supported elastically on a housing base 12. Thus, a whole casing is made the absorbing member of head driving repulsive force, exciting force applying to the disk spindle shaft and the head driving means is interrupted. The radial force exerted on the fixed shaft is reduced, thus, a bearing and the shaft are miniaturized and a shaft length is shortened. Further, by reducing the exciting force, the improvement of a positioning precision, that is, high density is attained.

摘要： PURPOSE:To obtain a high cooling effect and to prevent damage of an electrical heating element due to contamination around the electrical heating element by providing a contact surface for pressing and sliding a cooling member and a surface which contacts the cooling member through a gap where a thermally conductive liquid exists at a thermally conductive element which allows the heat to be conducted to the cooling member by pressing the electrical heating element elastically. CONSTITUTION:A thermally conductive heat-absorbing member 4 is pressed against an electrical heating element 5 which is fixed to a substrate 6 and a thermally conductive liquid 7 is filled into the gap to reduce thermal resistance on the surface of the electrical heating element 5. Heat of the electrical heating element 5 is propagated to a cooling member 2 through a heat-absorbing part 4 and an interlocking member 3 and is further propagated to a cooling member 9 and a cooling fluid 8 toward the outside finally. The interlocking member 3 is interlocked to the thermally conductive member cooling member 2 and the heat-absorbing member 4 so that it can rotate. Thus, the entire heat resistance can be reduced and damage of the electrical heating element due to wear powder can be prevented.

摘要： PURPOSE:To improve the positioning accuracy and to reduce noise and vibration by cancelling the resultant force of drive reactions of a positioning mechanism of a combined disk device. CONSTITUTION:When a read/write instruction is given from a control circuit 10, a positioning mechanism of a relevant magnetic disk device single body 12a applies read/write or positioning operation and the same operation signal is sent to the positioning mechanism of other single body 12b arranged intentionally from the single 12a. Thus, the drive reaction forces of the positioning mechanism moved acceleratingly are cancelled. The drive reaction forces are delivered via a link spring 18 and balanced, then the relative displacement of the drive reaction force of the single bodies 12A, 12B is reduced by selecting the spring constant of a spring 18.

摘要： PURPOSE: To prevent temperature rise of fluid in the suction chamber of a compressor by a method wherein fluid, whose amount is larger than the amount of fluid sucked by the compressor, is supercharged into the suction chamber and a part of the fluid is discharged to the outside of the suction chamber.
CONSTITUTION: A fan, connected to a crankshaft 3, is provided in the frame 4 of the compressor and the operating fluid, supercharged into the suction chamber 13, passes through a passageway means 14, introduced into the frame 4 and is discharged to the outside thereof from a discharging port 16. Accordingly, the inner wall of the suction chamber 13 is cooled by excessive operating fluid and the fluid, which deprives heat in the suction chamber 13, is sucked out by the fan an all times, therefore, the inside of the suction chamber may be maintained at a low temperature at all times.

摘要： PURPOSE: To contrive miniatruization and speed-up of the machine and prevent not only collision of both scrolls against the laps thereof but also damage due to the collision by a method wherein a balance weight is provided on the disc of a crank shaft while the rotary scroll is rotated by the crank shaft of fixed eccentricity to cancel centrifugal force.
CONSTITUTION: The balance weight 13, engaging with the disc 6B of the crank shaft 6, is rotated together with the crank shaft 6 by the rotation of the crank shaft 6 and the centrifugal force, opposing to the centrifugal force of the rotary scroll 2 and substantially equal to the same, is generated, thereby making the centrifugal force, acting on the rotary scroll 2, into zero. Accordingly, the centrifugal force of the rotary scroll 2 will never act on the bearings 5 of the main bearings 8, 9, and the miniatruization and speed-up of the device may be contrived and the capacity of the device may be enlarged. On the other hand, the rotary motion of the rotary scroll 2 is effected by the crank shaft 6 of fixed eccentricity, therefore, the troubles of the laps 1b, 2b of both scrolls 1, 2 due to the collision and damage caused by external vibrations may be prevented.

摘要翻译：目的：为了实现机器的微型化和加速，不仅可以防止两个卷轴碰撞，还可以防止由于碰撞造成的损坏，其中在曲轴的盘上设置有平衡重，而旋转卷轴由固定偏心的曲轴旋转以消除离心力。构成：与曲轴6的盘6B接合的平衡重13通过曲柄轴6的旋转和与旋转涡旋件2的离心力相反的离心力与曲轴6一起旋转，基本上相同，从而使作用在旋转涡盘2上的离心力为零。因此，旋转涡旋件2的离心力将不会作用在主轴承8,9的轴承5上，并且可以设计装置的微型化和加速，并且可以扩大装置的容量。另一方面，旋转涡旋件2的旋转运动由固定偏心的曲轴6实现，因此，由于外部振动引起的碰撞和损坏，两个涡卷1,2的圈1b，2b的故障可以防止。
