  • Publication number: 20240128347
    Abstract: A semiconductor device and a method of fabricating a semiconductor device, the device including a fin-type pattern extending in a first direction; a gate electrode extending in a second direction over the fin-type pattern, the second direction being different from the first direction; spacers on sidewalls of the gate electrode; a capping structure on the gate electrode and the spacers, the capping structure including a first capping pattern and a second capping pattern, the second capping pattern being on the first capping pattern; and an interlayer insulating film surrounding sidewalls of each of the spacers and sidewalls of the capping structure, the interlayer insulating film being in contact with the first capping pattern.

  • Publication number: 20190223389
    Abstract: Provided is a binding machine used to erect a post and bind a stem or branch of a plant to the post to enable the stem or branch to maintain a desired posture during the cultivation of fruits, vegetables, or flowers or gardening. The binding machine is configured not to allow an operating lever to be moved down when a binding tape is hooked to a tape pulling needle to prevent an erroneous operation while the binding tape is being drawn out and configured to prevent an iron pin bundle from being loaded upside down onto an iron pin supply part and to prevent an iron pin push bar from arbitrarily escaping the iron pin supply part and being lost when the iron pin push bar is separated from the iron pin supply part.

  • Patent number: 9736997
    Abstract: Disclosed is a binding machine for agriculture which is used when binding, using a binding tape, a crop to a pole which is previously installed near the crop so as to keep in places the stems or branches of various crops. A steel needle standby groove is formed at an inner side of the steel 5 needle exit of the steel needle supply part loaded with binding steel needles, and when steel needles are extruded, the steel needle is separated from the steel needle group and stands by in the steel needle standby groove, and in the steel needle extrusion plate, a steel needle separation protrusion is formed at a side surface 10 in the direction of the steel needle standby groove, and then the binding steel needle is extruded.

  • Patent number: 5824689
    Abstract: The jineol extracted from scolopendra subspinipes is represented as the following formula (I): ##STR1## The jineol is obtained from scolopendra subspinipes by extracting scolopendra subspinipes with a solvent, separating an activating portion from the extracted liquid with an organic solvent, and purifying an anticancerous activating portion from the activating portion by chromatography.The jineol derivatives prepared from the jineol extracted scolopendra subspinipes are represented as the following formula (II): ##STR2## wherein each R.sub.1 and R.sub.2, independently of each other, is a hydrogen; a lower alkyl group of C.sub.1 to C.sub.6 ; a cycloalkyl group of C.sub.5 to C.sub.7 having a substituting group; an alkyl group of C.sub.1 to C.sub.4 having a phenyl group with one to three substituting groups; a lower alkyl group of C.sub.1 to C.sub.6 having a hydroxy, an alkoxy having C.sub.1 to C.sub.5, or an aryloxy; a lower acyl group of C.sub.1 to C.sub.7 having a hydroxy, an alkoxy having C.sub.1 to C.sub.
