Abstract: A golf tee includes a stem positionable in or on the ground; and a head connected to the stem for supporting a golf ball. The head is configured to surround and support a portion of the golf ball, including the portion of the ball facing a golf player when positioned to hit the golf ball. The head includes a back portion configured to be impacted by a golf club of the golf player and two side portions extending from the back portion and wrapping around opposite sides of the golf ball to surround up to 180° of the circumference of the golf ball to inhibit side spin of the golf ball upon impact by the golf club. The back portion of the head of the golf tee includes a flat planar element extending substantially across the back portion and configured to provide a visual cue to guide the golf player to square the face of the golf club at impact when striking the golf ball.

Abstract: Disclosed herein is an O/W type emulsion comprising oils and milk characterized in that which comprises as an emulsifier polyethoxylated vitamin E in amount of 0.01 to 10% by weight. This emulsion may further contain vitamin E or its derivative.The emulsion according to the invention may stored for a long period of time without phase separation because polyethoxylated vitamin E contained therein forms microspheres in the interface of each emulsion particles. Further, it shows an improved activity of protecting the skin from the harmful oxygen species.

Abstract: An automatic document feeder installed on a copying machine. This document feeder is constructed such that one reversible motor provides the drive power for all of drive parts of the document feeder, that is, a document feeding part, a document conveying part and a document recovering part, thus substantially reducing the manufacturing cost of the feeder. The document conveyor belt, on which a document to be copied is closely laid, moves in the forward and reversed direction, thereby causing the document to be exactly set on a reference copying position of a contact glass of the copying machine and, in this respect, improving the operational efficiency of the automatic document feeder. The present invention also provides a control circuit for automatically controlling such an automatic document feeder.

Abstract: Plural through-holes are placed at a certain interval spacing on and along the grip of a brush to avoid slipping. Brush teeth and hard materials are implanted in a brush teeth implantation portion of the brush to facilitate the circulation of blood. The base and gripping portion of a rolling brush are connected by latches in opposite directions, and rotating directions can be selected at will. A passage is set along the center axis of the base of the brush, and plural connecting holes are arranged in the passage, reaching through to an outside round surface of the brush base. Implantation density of the brush teeth in the brush teeth implantation portion is not uniform.

Abstract: A device and a method for controlling a sorter. The device comprises a central control unit, an interface unit connected between a control unit of the copy machine and the central control unit, an one third rotation sensor for controlling operation of transfer wheels, a home position sensor for sensing home positions of bin trays and outputting a sensed signal to the central control unit, and a bin motor driving circuit adapted for controlling normal and reversed rotations of a bin motor.
