The disclosure provides a pull and a manufacturing method of the pull, which can mount an electronic component inside a handle part without damaging the electronic component and have favorable electronic functions. The pull of the disclosure is to be mounted on a slider for a slide fastener, and includes a ring part, an insertion part, the handle part, and the electronic component. The ring part is to be mounted on the slider. The insertion part is connected to the ring part for receiving an injection material. The handle part is formed sequentially on the insertion part by the injection material. The electronic component is mounted inside the handle part in a process in which the handle part is formed sequentially on the insertion part by the injection material.

A slide fastener tape member includes a tape body and a core string portion disposed at a tape side edge portion of the tape body along a length direction. The core string portion is formed by fixing a string member at the tape side edge portion along the length direction by machine sewing. The string member is fixed linearly such that at least one thread used for machine sewing crosses while contacting an outer peripheral surface of the string member without being pierced by a needle thread of machine sewing. Thus, since the core string portion can be easily provided by fixing the string member to the tape body having desired properties at a later stage, the value-added tape members can be easily manufactured at a relatively low cost.

To provide an electric slide fastener system, a radio transmitter, and a slider as a radio receiver that are able to operate adequately according to the state of an electric slider. An electric slide fastener system is provided with: a slide fastener chain including a pair of fastener tapes and element strips including a plurality of elements fixed to the fastener tapes; a slider configured to be movable relative to the slide fastener chain and including at least a power supply, a control part including a reception part for receiving a radio signal, and an output part including a drive part for driving an electric motor and a transmitting part for transmitting a drive force to the element strips; and a radio input part for transmitting by radio an instruction signal to the slider.

Provided is a fastener stringer including a row of metal elements having a plating film formed with improved thickness uniformity without waste, even if the elements are not electrically connected to each other in advance. For each of ten adjacent metal elements of the fastener stinger, 0.6D.sub.1/A.sub.12.0 is satisfied in which A.sub.1 represents an average value of thickness of the plating film for the ten metal elements at element center on either one main surface side of the fastener tape, and D.sub.1 represents thickness of the plating film for each of the metal elements at the element center on the one main surface side of the fastener tape.

A marking device performs a marking process onto a long object. The marking device includes a driving source and a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source. While the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit. An extent of interference by the marking unit to the transfer of the long object is reduced, thus facilitating higher speed transfer of the long object.

An element is configured to be installed together with a tape to form a fastener stringer, and includes: a main body including an upper main body and a lower main body; an installing portion for installing the tape; a head; and a neck connecting the main body and the head, wherein at least one of the upper main body and the lower main body includes a convex portion and a base portion, the convex portion protrudes from the base portion and extends in the left-right direction at an intermediate position in the front-rear direction. An inclined portion inclined downward along the left-right direction is formed on at least one side of the head along the upper-lower direction, and protrusions extending in the front-rear direction are formed on both sides of the convex portion.

Provided is a polyamide resin composition for a slide fastener that includes at least one polyamide resin and reinforcing fibers, wherein a total mass of the polyamide resin and the reinforcing fibers accounts for 90% by mass or more of the composition; wherein poly(m-xylylene adipamide) (MXD 6) accounts for 60% by mass or more of the polyamide resin; wherein reinforcing fibers account for 45 to 70% by mass of the total mass of the polyamide resin and the reinforcing fibers; wherein both first reinforcing fibers having a fiber diameter of from 5 to 7 m and second reinforcing fibers having a fiber diameter larger than that of the first reinforcing fibers by more than 2 m account for 90% by mass or more of the reinforcing fibers; and wherein the first reinforcing fibers account for 20% by mass or more and less than 50% by mass of the reinforcing fibers.
