Abstract: A swing training device includes a housing which contains a light source, a power source and a driving circuit for generating a beam, such as a laser beam. Suitable optics, such as a collimator lens and a beam splitter (such as a half-mirror or a prism) are placed in the housing in order to split a highly defined beam so that a first beam is radiated along the longitudinal axis of the golf club shaft and a second beam is radiated at roughly a 90.degree. angle with respect to the first beam. A gravity switch in the swing training device provides that the beams are only radiated during the backswing and follow through of a golf club, thus simplifying operation, saving power and reducing the likelihood of inadvertent radiation of the laser beam into the face of the golfer or bystanders. The invention may also include a mat which has indicia for properly aligning lighted dots generated on the mat by the laser beams in order that the golfer may develop a proper swing form.

Abstract: A composite medical treating device includes laminations of an n-type semiconductor film and a p-type semiconductor film coated on a surface of a ferrodielectric substance. When the composite medical treating device is affixed to a part of skin having a stiff portion and a pain, potentials of -, +, -, +, -, + are induced on a surface of the ferrodielectric substance in response to changes of potentials of +, -, +, -, + of the epidermis. Since the laminations of the n-type semiconductor film and the p-type semiconductor film are coated on the surface of the ferrodielectric substance, minus electricity is allowed to flow to the epidermis passing through the n-p laminations. However, plus electricity does not pass through the n-p (semiconductor) laminations and does not flow to the epidermis. Thus, the epidermis potential returns from plus to minus potential and is stabilized.
