A permanent-magnet stepping motor includes a stator which has resinous protrusions at its one end. An end plate disposed on one side of the stator is molded integrally with the stator. A flange plate is fixed to the other side of the stator, using the protrusions. The stator includes four stator yokes and two annular coils that are disposed at given positions. These yokes and coils are coupled together by molding a resin.

Chitin or chitin derivatives compounded with oral compositions such as dentifrice, mouth rinse, oral freshener, chewing gum and the like exhibit superior medicine effects for the prevention of dental caries, periodontoclasia and mouth odor. And, chitosan salt is also effective as the binding agent for use in the above mentioned oral compositions.
摘要:
Disclosed is a method of coloring an anodized and anodically reinforced aluminum or aluminum alloy article by cathodic treatment in a coloring solution wherein the cathodic electrolytic current is a negative voltage direct current having a duration substantially less than the interval therebetween and being repeated at a frequency sufficient to produce the required coloration.
摘要:
A jumping rail to be positioned within a trackway having a base, a platform defining a path and mounted to pivot with respect to the base between a first position wherein the platform is aligned with the base to permit a vehicle after passing over the platform to continue travelling along the trackway and a second position wherein the platform is raised upwardly from the base causing the vehicle to jump, a mechanism for normally urging the platform to its second position, a striking member extending from the base upwardly through part of the path defined by the platform and mounted to move between a first position wherein the striking member engages the platform retaining the platform in its first position and a second position wherein the striking member disengages from the platform permitting the platform to move to its second position, and an additional retaining mechanism for rendering the striking member inoperable so as to continuously retain the platform in its first position.

A toy crane provided with a base, a tower extending upwardly therefrom, a boom mounted to rotate about the tower, a carriage mounted to travel along the boom, an implement that may be raised and lowered from the carriage, and a control station permitting the child to select any one of three modes of operation, namely, rotation of the boom in a horizontal plane, raising and lowering of the implement with respect to the carriage, and movement of the carriage along the boom, and thereafter perform the selected operation by turning a hand crank mechanism. As an integral part of the toy crane mechanism there is provided a reciprocally mounted spur gear that is arranged to assume three distinct positions corresponding to the modes of operation, the spur gear forming an integral part of separate gear train systems operable by the crank mechanism for performing the above-noted functions.

A pH adjusting system includes a water pit for refueling 35 that is disposed in a reactor container 10, which stores a reactor, and is capable of storing cooling water and a pH adjusting apparatus 37 that is disposed above the water pit for refueling 35 and houses a pH adjuster. The pH adjusting apparatus 37 causes a pH-adjusted solution generated by dissolving or mixing the pH adjuster to flow out to the water pit for refueling 35 below the pH adjusting apparatus 37. Consequently, even when it is difficult to dispose the pH adjusting apparatus on a floor of the water pit for refueling, it is possible to suitably perform pH adjustment in the reactor container 10.
