  • Publication number: 20220195185
    Abstract: The present invention is a polyamide resin composition which contains 50 to 90% by mass of a crystalline polyamide resin (A) and 9 to 49% by mass of a talc (B). The average particle size of secondary particles of the talc (B) in the polyamide resin composition is 30 ?m or less. The polyamide resin composition has an exothermic peak present on a high temperature side of a maximum exothermic peak of a crystallization temperature during cooling in a cooling process of measurement by means of a differential scanning calorimeter. Variations in physical characteristics such as a molding shrinkage, mechanical characteristics, and a heat distortion temperature of the polyamide resin composition are suppressed among different production machines or different production lots. Consequently, characteristics within desired ranges are stably obtained.

  • Publication number: 20220162381
    Abstract: The present invention is a polyamide resin composition containing 50 to 90% by mass of a crystalline polyamide resin (A) and 9 to 49% by mass of a talc (B), and preferably further containing a coupling agent (C) and a fatty acid metal salt (D), in which an average particle size of secondary particles of the talc (B) in the polyamide resin composition is greater than 30 ?m. The polyamide resin composition is less likely to cause a poor appearance of a molded article or occurrence of sink marks, and can stably provide characteristics within desired ranges.

  • Patent number: 9234079
    Abstract: Provided is a method for producing an aqueous modified polyolefin dispersion composition that is industrially excellent, the method comprising the steps of preparing an aqueous modified polyolefin dispersion that does not contain a surfactant, and then mixing a specific surfactant, whereby foaming can be suppressed during the removal of the organic solvent, and the processing time can be significantly reduced. The method for producing an aqueous modified polyolefin dispersion composition comprises the steps (1) and (2): (1) step 1 of obtaining an aqueous modified polyolefin dispersion using a modified polyolefin, an organic solvent, a base compound, and water as starting materials; and (2) step 2 of mixing a surfactant with the aqueous modified polyolefin dispersion in an amount of 0.1 to 10 wt. % based on the weight of the modified polyolefin.

  • Patent number: 5062373
    Abstract: A device for transferring buttons in succession to a button sewing machine in such a manner that they are forcibly fed from a button storage unit by a rotary disk with button insert holes through which the individual button drops into a button holder when each of the insert holes align with a button discharge hole.

  • Patent number: 5007033
    Abstract: A world timepiece for normally displaying the time of a home city and for selectively displaying the time of another city situated in another time zone. The world timepiece includes a plurality of selector switches corresponding to main cities located in different time-lag zones into which the world is divided. A display unit normally displays the time of the user's home city and, upon actuation of one of the selector switches, the display unit displays the time of the selected city designated by the actuated selector switch. A city of an arbitrary time-lag zone can be stored in an assigned city storage circuit, and the time of the assigned city can be displayed by the display unit by actuating an optional switch.

  • Patent number: 4920238
    Abstract: A self-centering switch is provided with a rocker bar pivotally mounted to move between a neutral and an actuated position. A contact element having a pair of contact bearing resilient arms is mounted at the pivot axis of the rocker bar. The resilient arms are biased against the rocker bar and act to return the bar to its neutral position. The contact element may be connected to a control circuit formed on a circuit board and having one or more fixed contacts alternately engageable by the contacts on the resilient arms.

  • Patent number: 4712493
    Abstract: A button sewing machine allows simultaneous sewing of both a stay button and a surface button to a workpiece and conducts button-neck-wrapping by inclining both buttons with a workpiece. A needle is arranged to travel between an upper needle bar spindle and a lower needle bar spindle, being received by each spindle alternately per each needle stroke, such that buttons are sewn in a manner closely simulating "hand" sewing. A worktable is arranged to move in both the X and Y directions in accordance with the button hole pitch distance in synchronization with the up and down motion of the needle.
