In the reverse opening slide fastener, an insert pin includes a side edge arranged at a box pin side and a side edge arranged at a tape inner side. A first sloped section sloped in a direction to be apart from the box pin side toward the insert pin top end is formed at the side edge arranged at a box pin side. The first sloped section is formed as being intersected with an extension line obtained by extending a planar section of the side edge arranged at a tape inner side to the insert pin top end side and has a shape sloped at an angle to be contacted to a guide column of the lower slider or to be apart from the guide column when the insert pin is inserted to upper and lower sliders. Accordingly, in the reverse opening slide fastener, insertion operation of the insert pin can be smoothly performed.

A slide fastener includes a pair of first and second fastener stringers, a box pin, an insert pin, and a pair of first and second sliders. The box pin has a box pin body, a stopper portion arranged at a front end side of the box pin body, and suppressing portions projected on at least one of upper and lower surfaces of the box pin body to suppress sliding of the second slider. Further, the box pin body has a body region, and a notched region arranged at an element-row-side base end portion and having excluded a side surface portion at a side facing the insert pin. The suppressing portions are projected in only the notched region. With this arrangement, the second slider can be stably held at an insert-pin inserting position, and a subsequent insert operation or extract operation of the insert pin can be smoothly performed.

The reverse opening type slide fastener has a separable bottom end stop including upper and lower sliders, wherein a stopper for preventing the lower slider from slipping off is provided at the bottom end of a box pin. A first engaging portion is formed on an opposite side edge opposite to an insert pin of the box pin and a second engaging portion is formed on an opposite side edge opposite to the box pin of the insert pin to position the insert pin in a downward direction when the second engaging portion engages the first engaging portion. A projecting portion which makes contact with the inner face of the blade of the upper slider to suppress a free sliding of the upper slider, is formed on at least any one of front and rear side faces opposite to the inner face of the blade of the upper slider of the box pin.

A revolving magnetic field type motor has a rotor and a stator. The rotor has a plurality of permanent magnets. The permanent magnets defines a plurality of rotor magnetic poles. The number of the rotor magnetic poles is “P”. The rotor has a plurality of blocks aligned in the rotor's axial direction. The number of the blocks is “m”. Each block has a set of the rotor permanent magnets. One set of the permanent magnets is offset relative to an adjacent set of the permanent magnets by a predetermined offset angle in the rotor's rotational direction. The stator has a plurality of coils, the coils defining a plurality of stator magnetic poles around the axis of the stator, the number of the stator magnetic poles being “T”. The predetermined offset angle is selected from within a range from about zero degrees/((m−1)×n) to about 22.5 degrees/((m−1)×n). The number of the rotor magnetic poles “P” is 8n (n is an integer equal to or greater than one). The number of the stator magnetic poles “T” is 9n (n is an integer equal to or greater than one). This motor reliably decreases cogging torque.

Engaged portions formed on a tab holder are elastically engaged and attached to engaging portions formed on a first column portion and the rear side of a second column portion on an upper blade, and a pair of protrusions formed on the inner side of the tab holder are fitted in a recession formed on an inclined surface of the first column portion and a recession formed on an inclined surface of the second column portion. Further, stepped portions formed at both edge portions of both front and rear ends of the tab holder are brought in contact with end surfaces and inner sides of support walls installed at both edge portions of inclined surfaces. The slide fastener can improve attachment strength of the tab holder, implement excellent durability for a long period of time, excellent external appearance, and excellent assembly performance.

A nonvolatile memory element capable of using desired ferroelectric materials, exhibiting a high reliability and performing processings such as reading of information without destruction of stored contents is provided. A memory cell comprises two capacitors Cf1 and Cf2 connected to each other in series. Both capacitors are ferroelectric capacitors manufactured by the same steps. Accordingly, the coupling ratio between both capacitors can be changed by only the change of surface areas thereof. A voltage corresponding to the information to be stored is applied to the opposite ends of the memory cell 20 to cause polarization reversal and as a result, the information is written thereinto. In order to read the stored information, a ground potential is applied to the opposite ends of the memory cell 20. On the basis of the potential generated at a connection 20c upon the application of the ground potential, the information can be read.
