The introduced air passes through the infrared ray projector and is blown to where a user's hands are placed such that hands are rapidly dried by hot air and heat, infrared rays, and infrared rays generated by the infrared ray projector and the infrared exothermic device prevent and remove the inhabitance of bacteria causing various diseases on the hands. Thus, a user can maintain his/her hands at sanitary state. Due to the increased temperature, the apparatus of the present invention exhibits fomentation and the far infrared rays are helpful to hand skin care and health. Moreover, the low-level laser beam is projected to hands to activate the treatment of affected parts and various hand diseases, resulting in aiding health. Since a single apparatus performs various and multiple functions, the hand skin care apparatus is variously used, has various effects. Moreover, economic value and utility of the hand skin care apparatus are enhanced.

摘要： A semiconductor device having a thyristor-based memory device exhibits improved stability under adverse operating conditions related to temperature, noise, electrical disturbances and light. In one particular example embodiment of the present invention, a semiconductor device includes a thyristor-based memory device that uses a shunt that effects a leakage current in the thyristor. The thyristor includes a capacitively-coupled control port and anode and cathode end portions. Each of the end portions has an emitter region and an adjacent base region. In one implementation, the current shunt is located between the emitter and base region of one of the end portions of the thyristor and is configured and arranged to shunt low-level current therebetween. In connection with an example embodiment, it has been discovered that shunting current in this manner improves the ability of the device to operate under adverse conditions that would, absent the shunt, result in inadvertent turn on, while keeping the standby current of the memory device to an acceptably low level.
