Abstract: A semiconductor device includes: an ESD protection circuit including a first n-channel MOS transistor provided between a signal terminal and a ground wire; and a control circuit electrically connected to the signal terminal, wherein, while a signal of a high level is being supplied to the signal terminal, the control circuit outputs a first voltage dropped from a high-level voltage of the signal to a gate of the first n-channel MOS transistor, and in response to a surge due to ESD being input into the signal terminal, outputs a second voltage lower than the first voltage to the gate of the first n-channel MOS transistor.

Abstract: A slider for slide fastener includes: a slider body including an upper blade and a lower blade which are separate from and face each other in an upward and downward direction, and a guide post which connects the upper blade and the lower blade on a front end side; and a pull tab which is attached to the slider body. A cutout region is formed in at least one of both sides in a width direction of the upper blade, the both sides in the width direction sandwiching the guide post. The cutout region is formed of a side edge portion extending toward an outer side in the width direction of the guide post and being arranged along a front and rear direction, and a front edge portion.

Abstract: A slider includes a slider body and a pull. The slider body includes an upper blade and a lower blade arranged to be spaced from each other in an up-down direction and to be parallel to each other, a guide post connecting the upper blade and the lower blade, and a pull attachment portion provided on an upper surface of the upper blade. The pull is attached to the pull attachment portion. A cut-out portion is formed on a front end portion of the upper blade at one of left and right sides with respect to the guide post. The cut-out portion is formed to be positioned at a rear side than a front end portion of the upper blade at the other of the left and right sides with respect to the guide post and than a front end portion of the lower blade.

Abstract: There is provided a slider cover of a slide fastener. An upper mounting plate includes: an upper plate to be arranged above an upper blade of a slider and formed with a through-hole penetrating therethrough; and an upper wall protruding downward from the upper plate. A lower mounting plate includes: a lower plate to be arranged below a lower blade of the slider; and a lower wall for surrounding front, right and left sides of an outer periphery of the lower blade and protruding upward from the lower plate. At least one of the upper and lower mounting plates includes a protrusion protruding from an inner peripheral surface of at least corresponding one of the upper and lower walls and configured to come in close contact with a part of an outer peripheral surface of at least corresponding one of the upper and lower blades.

Abstract: A fastener element has a central land portion and first and second bulging portions bulging from the central land portion toward the tape front surface side and the tape rear surface side in the element thickness direction. The first and second bulging portions respectively have a bulging end surface facing to the element thickness direction. The bulging end surface has a quadrilateral base end surface which is long in the element length direction and a tapered protrusion end surface protruding from the base end surface in the element width direction. Thus, it is possible to make the fastener element look like a single-sided metal element and to make a slide fastener which is formed by using the fastener elements lighter than a conventional slide fastener having single-sided metal elements.

Abstract: Provided is a polyamide resin composition that is suitable as a material for slide fastener parts having good strength after being dyed. A polyamide resin composition for a slide fastener, comprising a polyamide resin and reinforcing fibers, wherein a total mass of the polyamide resin and the reinforcing fibers is 90% by mass or more of the composition; wherein a proportion of an aromatic polyamide having a melting point of from 200 to 250° C. in the polyamide resin is more than 70% by mass; and wherein a content of the reinforcing fibers in the total mass of the polyamide resin and the reinforcing fibers is from 45 to 70% by mass.

Abstract: Provided is an injection molded element for a slide fastener which retains a high degree of practical strength, which does not cause undulation of a fastener tape after attachment thereto, and which has superior moldability. The present invention is an injection molded element for a slide fastener having as a material a polyamide resin composition containing a polyamide resin having a glass transition temperature from 40 to 70° C., the composition having a melt flow rate from 5 to 40 g/10 min, and containing from 40 to 60 parts by mass of the reinforcing fibers per 100 parts by mass in total of the polyamide resin and reinforcing fibers.

Abstract: There is provided a slider cover of a slide fastener. An upper mounting plate includes: an upper plate to be arranged above an upper blade of a slider and formed with a through-hole penetrating therethrough; and an upper wall protruding downward from the upper plate. A lower mounting plate includes: a lower plate to be arranged below a lower blade of the slider; and a lower wall for surrounding front, right and left sides of an outer periphery of the lower blade and protruding upward from the lower plate. At least one of the upper and lower mounting plates includes a protrusion protruding from an inner peripheral surface of at least corresponding one of the upper and lower walls and configured to come in close contact with a part of an outer peripheral surface of at least corresponding one of the upper and lower blades.

Abstract: These fastener elements have: an element main body portion having a coupling head portion; and first and second projections that project in a tape surface/rear-surface direction from the element main body portion. The first and second projections have a top surface, peripheral side surfaces standing upright from the element main body portion, and at least one sloped surface between the top surface and the peripheral side surfaces that has a different angle of inclination from the top surface and the peripheral side surfaces. As a result, the fastener elements appear long and narrow in the element length direction and have an external appearance close to that of a metal element. Furthermore, a stop claw portion is less likely to catch on the fastener elements when starting the sliding operation of a slider.
