Title: Contact electrifying device
Inventor: NAKAMURA TOSHIHARU
IPC: G03G15/02
Filed: 1987-09-14
Abstract: PURPOSE:To perform uniform electrification which generates no leak regardless of a surface defect of a body to be electrified by bringing the outermost resistance layer which contacts the body to be charged and making its volume resistivity larger than that of a resistance layer below it. CONSTITUTION:The outermost resistance layer 22 which contacts the body 1 to be electrified becomes larger in volume resistivity than the resistance layer 21 below it by contacting the outermost layer. Then a voltage applied to a conductive base 20 from outside 3 can be applied efficiently to the body 1 to be electrified and when the body 1 has a surface layer defect such as a pinhole, an excessive current flows to the part to reduce a voltage drop as much as possible. Consequently, a defect in electrification due to the damage of the surface of the body such as the photosensitive body, etc., of the contact electrifying device is eliminated and uniform electrification performance is obtained.

Title: Light scattering type liquid crystal display element
Inventor: KITAMURA TERUO
IPC: G02F1/1333
Filed: 1991-09-11
Abstract: PURPOSE:To obtain a liquid crystal display element having high transmissivity in a bright area, higher contrast, and high reliability by using a metal oxide layer for which liquid crystals are dispersed in a transparent metal oxide matrix. CONSTITUTION:On transparent substrates 1, 6 a transparent electrode 2 having a desired pattern is formed and a metal oxide layer 3 in which nematic liquid crystals 4 are dispersed granularly is held there between. Therefore, this layer is formed as a complete metal oxide by irradiation of light and heat so that it is extremely stable physically and chemically. Namely, no absorption of water is caused even when the element is left in normal air. Deterioration can be prevented not only in the matrix part of the metal oxide layer 3 but in the liquid crystal dispersed therein. Since the layer 3 has high hardness, the leakage of the liquid crystal or the variation of the interval between the substrates is prevented. Therefore, a sealing member which is essential for a conventional liquid crystal element is not necessary. This display element may have only single sheet of substrate 1 since the metal oxide layer 3 has high hardness.

Title: Method for transferring thin film element
Inventor: AZUMA SEIICHIRO
IPC: H01L27/12
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To transfer a silicon thin film element onto an arbitrary substrate without elevating the substrate temperature by irradiating a sacrifice layer on a first substrate while applying a voltage and transferring a thin film element on the sacrifice layer onto a second substrate. SOLUTION: A sacrifice layer 206 of amorphous silicon absorbing laser light 208 efficiently is formed on a substrate 207 of quartz glass. A buffer layer 205 of silicon dioxide is formed thereon in order to prevent thermal or optical influence on an upper element at the time of transferring the element. Subsequently, an electrode 204 is formed to be connected electrically with the sacrifice layer 206 and a bias voltage is applied to the sacrifice layer 206. Under that state, the sacrifice layer 206 is irradiated with pulse excimer laser light 208. When the temperature of the sacrifice layer 206 increases over a melting point through irradiation with laser light 208, it is melted and an appropriately set current flows easily through the sacrifice layer 206.  Since the sacrifice layer can be formed according to a conventional process, impurities have no adverse effect on the fabrication of an element.
