Rotating electrical machine

InactiveCN105122606AImprove cooling effectSuppression of rising manufacturing costsCooling/ventillation arrangementEngineeringCentrifugal fan
A mist is generated by scooping up cooling oil using a lower end portion of a non-load side end plate. Air containing this mist is circulated by a centrifugal fan provided to a load side end plate to form a recirculating air current flowing through first through-holes in a rotor core and through a ventilation passage on the outside of a rotor in opposite directions. According to a cooling mechanism as above, a mist generated in at least one point in the housing can be supplied with the recirculating air current to every point across a whole area within the machine. Hence, both of the rotor and a stator can be cooled efficiently with a small amount of mist.

syringe

A syringe (1B) comprises: a syringe body (1C) including a plunger (32) to be operated for injection of a drug solution; a cylindrical needle cover (11B) housing an injection needle (100A); and a spring (18) held in a compressed state by the needle cover (11B). The needle cover (11B) has seats (153A) and (155B) in a pair that abut on corresponding opposite ends of the spring (18) to restrict the position of the spring (18). Pushing in the plunger (32) further after injection deforms the seat (155A) to release restriction on the spring (18). The spring (18) free from the restriction abuts on the syringe body (1C). This biases the needle cover (11B) to move the needle cover (11B) to a position where the injection needle (100A) is housed.

One rotation of the input shaft (7) moves the rollers (19) in the circumferential direction by a distance corresponding to a tooth of the internal teeth (4) to rotate the output shaft (12) at a reduced speed. A circular protrusion (21) is provided between the two eccentric circular plates (9), and staking protrusions (22) are provided at axially opposing ends of the eccentric circular plates (9). The staking protrusions (22) and the annular protrusion (21) prevent the bearing (11) from moving in the axial direction.

Knitting method of tubular fabric and weft knitting machine

A knitting method of a tubular fabric and a weft knitting machine in which knitting efficiency can be enhanced. As shown in (a) as a variation in moving speed (V) with time t, a tubular fabric intersecting at the opposite ends is knitted by a weft knitting machine having a pair of needle beds such as a front needle bed (FB) and a back needle bed (BB) while a phase difference is imparted as shown by a single dot chain line and a double dots chain line. The phase difference is provided in order to leave an interval for preventing interference of knitting needles advancing from the front and back needle beds to the tip part and performing knitting operation. A position where an knitting operation is performed by driving the knitting needles changes depending on the position of a carriage reciprocating in the longitudinal direction of the needle bed while mounting a cam system. A fabric is knitted while being duplicated by means of the front and back needle beds (FB, BB) and a fabric substantially doubling that by the conventional circling knitting shown in (b) is knitted in a single stroke of the carriage, thus enhancing productivity.
