Inventor: YABE AKIO
IPC: G03G5/05
Filed: 1989-06-22
Abstract: PURPOSE:To improve printing resistance without degrading sensitivity characteristics by using a polyether sulfone resin for the binder polymer of a charge transfer layer. CONSTITUTION:This photosensitive body is constituted by successively laminating a charge generating layer 2 and the charge transfer layer 3 on a conductive base 1.

Title: Low-frequency-band azimuth calculating device
Inventor: KOBAYASHI OSAMU
IPC: G01S3/16
Filed: 1989-06-22
Abstract: PURPOSE:To obtain a high-accuracy azimuth in a low frequency band by using antenna orders by directions and amplitudes by the antenna orders, or a table between adjacent antennas. CONSTITUTION:An antenna table 10 is provided with the antenna orders by the azimuths (at intervals of 1 deg. from 0 deg. to 359 deg.) and amplitude difference by the antenna orders or the table between the adjacent antennas. When a radio wave from a target radio source 1 is inputted to an azimuth search antenna 1, a calculator 2 for amplitude values by antennas calculates the input amplitude value of each antenna. An amplitude order rearranging device 7 rearranges antenna bars in decreasing amplitude order. An amplitude difference calculator 8 calculates amplitude differences between adjacent rearranged antennas. Then a comparator 9 for the amplitude values by the antenna orders uses the table 10 and use the amplitude differences between all the antennas to calculate the azimuth. Consequently, the precise azimuth can be calculated even with an antenna pattern which is wide in the same amplitude difference range.

Title: Production of optical disk
Inventor: HIROKANE JUNJI
IPC: G11B7/26
Filed: 1992-06-19
Abstract: PURPOSE:To produce the optical disk having excellent reliability and high quality. CONSTITUTION:A liquid resin 3 is applied on the surface of a substrate 1 rotated at a first rotating speed W1. The film thickness of the resin film 3a formed on the surface of the substrate 1 is controlled by rotating the substrate 1 at a second rotating speed W2. The build-up part 4 of the undried excess resin 3 existing in the outer peripheral part of the surface of the substrate 1 is removed by rotating the substrate 1 at a third rotating speed W3. As a result, the photoresist film and protective film which are decreased in the build-up parts to the permissible limit or below and have the uniform film thicknesses are formed. The patterns of guide tracks, etc., are transferred with high accuracy when a photoresist is formed. The irradiation dose of UV rays, etc., are minimized and the process time is shortened; in addition, such things that the build-up parts peel after curing and give damages, such as corrosion on the recording layer do not arise.

Title: Image forming device
Inventor: OBARA YASUNARI
IPC: B65H5/38
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To make a surface of a carrying passage hard to be electrified, and to restrain abrasion by a transfer material by covering a surface of the carrying passage slidingly rubbing with the unprinted surface side or one printing surface side of the transfer material with a low frinction resin. SOLUTION: A surface of a carrying passage slidingly rubbing with the unprinted surface side or one printing surface side of a transfer material is covered with a low friction resin. For example, in a carrying guide having a resin carrying guide 103 molded by an ABS resin, a material applied with an adhesive to a sheet 104 of a fluororesin having a surface having an adhesive surface of polytetrafluoroethylene is bent with the rib apex as the center to be adhered to a side surface of a rib. Thus, a low frictional carrying rib can be obtained to a transfer material by forming a thin film fluororesin layer having a thickness of about 20 to 200 μm on a rib surface to thereby eliminate the occurrence of image scattering as well as to reduce an abrasion quantity.

Abstract: PURPOSE: To enable measurement with the same unit even to any types, by the constitution of the two sets of transmission lines of one set by two lines, one end of which is commonly connected to the input and output terminal of element, in the AC performance measurement of high speed element of the same terminal construction and of many types.  
     CONSTITUTION: The transmission line 13 added newly has the same characteristics impedance as the transmission lines 6W8. Further, the termination circuit 14 has the same resistance as the characteristic impedance of the transmission line 7. The characteristic impedance of the transmission lines 6W7, 13 is made twice the value of the output load resistance condition at the AC performance measurement of the high speed element 1. Further, the transmission lines 7, 8 connecting the measuring units 9, 11 at their termination are of the same performance and the length is made equal. Thus, since the time of signal to be transmitted in the transmission line 7 and that transmitted in the line 8 are made equal, the AC performance of the high speed element 1 can be measured by comparing the signals observed at the measuring units 9, 11.

Abstract: PURPOSE:To produce nitrided cast iron parts having high resistance to corrosion, particularly high resistnce to corrosive wear by grinding the surface of a cast iron blank material after nitriding and coating and rubbing water glass contg. iron powder on said surface then drying the surface and subjecting the same to nitriding. CONSTITUTION:When the surface of a cast iron part is subjected to primary gas soft nitriding to form a nitrided layer 10 thereon, the surface is hardened; at the same time, the parts of graphite 12 build up. Clearances are generated between the graphite 12 and base material part 14 around said graphite owing to thinning of the graphite. The build-ups on the surface are honed to a smooth surface. Water glass 17 added with 20-80vol% iron powder 16 is coated on the surface and the surface is subjected to rubbing with a rubber grindstone whereby the surface is sealed. The cast iron part is subjected to secondary gas soft nitriding after drying in the atmospheric air. Then the iron powder 16 is hardened and expanded to cover the clearances in the layer 10, thereby improving the sealing effect.
