Title: Detector
Inventor: NAKAYAMA TOSHIO
IPC: H01L21/312
Filed: 1986-03-25
Abstract: PURPOSE:To realize a detector for microwave and infrared regions having high detection sensitivity and stably operating by forming the thin-film laminated structure of MIM structure and using a Langmuir-Blodgett's film as an insulator. CONSTITUTION:An Al strip 2 is evaporated onto a glass substrate 1, and a stearic acid LB film (a Langmuir Blodgett's film) is accumulated on the substrate. The whole is dried sufficiently, and an Al strip 3 is shaped again so as to cross at right angles with the substrate strip 2 and cross at mutual width points. Accordingly, an MIM (a metal-an insulator-a metal) type detector using the Al strips as antennae combining lead electrodes and employing the stearic acid LB film as an insulating layer is constituted.

Title: Roller for electrophotographic copier
Inventor: NAMIKI RIYOUICHI
IPC: G03G15/10
Filed: 1978-05-30
Abstract: PURPOSE: To prevent unevenness from occuring in each part when the roller is used for rollers such as of charging, developing, transfer and cleaning by mixing 1 to 50wt% of carbon fibers into rubber elastic material thereby poviding conductivity.  
     CONSTITUTION: Carbon fibers are mixed in rubber elastic material in a range of 1  to 50wt%, preferably 1 to 35wt%. It is also equally satisfactory to further mix carbon power such as of Al, Cu or metal powder such as of Ag within a range of 0.1  to 50wt%. However, it is necessary that the total amount of the carbon fiber and  carbon powder or metal powder be kept at less than about 50wt%. If the carbon  fibers are mixed in the rubber elastic material, the roller added with these even if  slight becomes conductive because the carbon fibers per se are conductive. However, if the amount of mixing of the carbon fibers is less than 1wt%, the strength of  the roller is not sufficient and if it exceeds 50wt%, it is practicably infeasible to  form the roller of good surface characteristic.
