Abstract: A golf ball for the putting practice is provided, which enhances accuracy of putting and enables to easily modify posture and putting angle of a golfer in putting. A golf ball for the putting practice comprises: a center-pin(110) protruded from both sides of the golf ball along the arbitrary straight line passing through the center of the golf ball(100); a collimation indicator(120) which is positioned on the line vertically dividing the center-pin; and a line-of-sight(130) formed in the outer side of the collimation indicator in the surface of golf ball along the straight line passing through the center of the golf ball and vertically dividing the center-pin.

Abstract: 본발명은시트절단용슬리터에관한것으로, 와인딩롯도(20)를소정높이로고정시키는유압실린더(50)와, 공압게이지(40)에미리설정된압력이상의압력이터치로울러(30)에인가되면작동하는유압제어밸브(70)와, 상기유압제어밸브(70)의작동에의해상기공압게이지(40)에미리설정된압력을유지하도록작동하는공기실린더(80)와, 상기터치로울러(30)에인가되는압력에따라, 상기유압제어밸브(70)와공기실린더(80)가서로연동하도록상기유압제어밸브(70)와공기실린더(80)에부착된작동롯도(60)로구성되는것을특징으로한다. 본발명의슬리터에의하면, 와인딩샤프트에감기는원단의하중이커짐에따라기계식유압장치가와인딩롯도를들어올려줌으로서터치로울러가받는압력은항상일정하므로, 원단이구겨지거나밀리지않고똑바로감을수 있으며, 또한, 원단의종류에따라와인딩되는정도를작업자가미리설정할수 있으므로, 규격이통일된고품질(high quality)의제품을생산할수 있는효과를가진다.
