The present invention relates to a multi-blade electric rotary razor which comprises a razor blade cartridge turned by a motor, and at least one pair of razor blade assemblies disposed at an equal-angle distance at the razor blade cartridge along a direction in which the razor blade cartridge rotates, at least one pair of razor blades (hereinafter referred to as first razor blades) being arranged in an overlapping manner at a predetermined distance at the razor blade assembly along a radius direction of the razor blade cartridge. The electric rotary razor of the present invention has a structure of a wet shaver where multiple razor blades are arranged, and uses the motor to turn the razor blade cartridge during shaving for user convenience and thorough shaving. The multi-blade razor blade assembly alleviates a dermal stimulation, minimizes a possibility of a scar, and does not require shaving cream, making shaving convenient and unhindered by time and space.

A composition for producing an organic insulator is provided which comprises an organic-inorganic hybrid material (as defined). The hybrid material shows high solubility in organic solvents and monomers, and superior adhesion to substrates. In addition, the hybrid material displays a high dielectric constant and a high degree of crosslinking. Based on these advantages, the composition comprising the organic-inorganic hybrid material can be utilized during the fabrication of various electronic devices by a wet process. A method for producing the organic insulator while utilizing the composition also is provided, as well as the resulting organic insulator, and an organic thin film transistor which incorporates the resulting insulating layer.

Provided are a method and apparatus for inputting handwriting in a digital electronic apparatus. Various patterns defining methods of generating pressure information according to handwriting input are stored in advance, and a user selects a pattern similar to a pattern of the user or selects a desired handwriting pattern to perform the handwriting, so that pressure information is generated according to the handwriting pattern and the handwriting is displaying with a thickness corresponding to the pressure information. Therefore, it is possible to solve a problem of monotonous handwriting input in the related art where only the position is input and the handwriting is output with the same thickness.

Provided are a stereoscopic image display unit having a 3D information input device and a 3D stereoscopic image display method using the 3D information input device. The 3D information input device receives a synchronization signal used for a conventional stereoscopic image display unit and generates an ultrasonic signal. The stereoscopic image display unit receives the ultrasonic signal through the ultrasonic wave reception units installed at a plurality of areas and measured a distance between the 3D information input device and each of the ultrasonic wave reception units by using a time difference between a generation time of the synchronization signal and a reception time of the ultrasonic signal and measures a position of the 3D information input device in a 3D real space by using the distances. The measured position of the 3D information input device in the 3D real space is converted into a coordinate in the 3D stereoscopic image space. A position of the 3D information input device functioning as a mouse or a remote controller is stereoscopically displayed on the 3D stereoscopic image, so that click information or menu selection information can be input. A synchronization signal logic used for a conventional stereoscopic image display unit is employed, so that it is possible to embody a 3D remote controller or a 3D mouse without an increase in cost caused by addition of the configuration.
