Title: High-molecular ptc composition and high-molecular ptc device
Inventor: SEKI DAISUKE
IPC: H01C7/02
Filed: 2001-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a method of restraining an oxidative deterioration from occurring in a high-molecular PTC composition when subjected to a thermal history, where the PTC composition is composed of a binder whose main component is a crystalline high-molecular composition and metal carbide as conductive powder mixed into the binder and kneaded together. SOLUTION: Transition metal functions as a catalyst to cause an oxidative deterioration to a high-molecular compound, so that a surface modifying agent film is formed on the surface of metal carbide powder so as to prevent the metal carbide powder from coming into contact with a binder. At this point, when the film is an insulator, it deteriorates the characteristics of a high-molecular PTC device, so that boron polymer is used as conductive surface modifying agent.  Even if a high-molecular PTC device, which is composed of the high-molecular PTC composition and electrodes formed on both the sides of the PTC composition, undergoes a thermal history as it carries out a switching operation repeatedly, the oxidative deterioration occurs less in the binder, so that the binder is hardly increased in volume with the oxidative deterioration, and the high-molecular PTC composition varies less in resistiveity at a room temperature.

Title: Image forming apparatus
Inventor: KAMOSHITA SHINICHI
IPC: B41J2/395
Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus wherein forming of an electrostatic latent image can be stably performed by preventing a foreign matter from being stuck to a writing electrode, the apparatus can be reduced in size to be compact and a material is not limited. SOLUTION: When an image is written by moving an electric charge to a writing layer 2b of an image carrier body 2 by means of a writing electrode 3b, an electrically conductive developing roller 5a functions as a counter electrode. As a result, an electrostatic latent image is formed on an electrically conductive layer 2c of the image carrier body 2 and at the same the electrostatic latent image is developed by a developer 4. As the electrically conductive developing roller 5a functions as the counter electrode, a specifically dedicated counter electrode is not necessary. The number of components is reduced and the apparatus is reduced in size to be compact. Moreover, as the developing is performed concurrently with the forming of the latent image by means of the developing roller 5a, the image forming process can be simplified.

Title: Method for correcting pattern position deviation and defect inspecting apparatus
Inventor: ISHIMORI HIDEO
IPC: H01L21/60
Filed: 2001-09-28
Abstract: PROBLEM TO BE SOLVED: To enable high-speed alignment at an adjacent comparison time between patterns of chips. SOLUTION: A displacement signal is formed by binarizing a reflecting light luminance signal from a sample surface to be inspected. A predetermined rectangular region in the displacement signal is made a first region. A lateral (X) direction of the rectangular region is made a first direction, and pixel values along the first direction are accumulated to obtain a first direction cumulative value. A second direction profile is formed by sequentially arranging the first direction cumulative values in a second direction. Position information of edges of a repeating pattern is detected on the basis of the formed second direction profile. A deviation width of how much adjacent chips deviate in the second direction is detected on the basis of the edge position information, and the deviation width is corrected.  A longitudinal (Y) direction is made the first direction and the same process is carried out. A two-dimensional deviation width is corrected in this manner.
