Title: Tilt measurement method for optical record medium
Inventor: KAKINUMA KEIJI
IPC: G11B7/26
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a tilt measurement method measuring a tilt of an optical record medium such as a one side double layer disk etc., having a translucent film and a reflection film at every film. SOLUTION: In this method, the tilt of the optical record medium having the translucent film 8 and the reflection film 3 is measured. In such a case, reflection beam intensity from the translucent film 8 and the reflection beam intensity from the reflection film 3 are calculated, and this method is constituted so that the smaller intensity side between the reflection beam intensity from the translucent film 8 and the reflection beam intensity from the reflection film 3 is filtered. In such a constitution, since the reflection beam from the translucent film 8 is tilt measured separately from the reflection beam from the reflection film 3, the optical record medium such as the one side double layer disk etc., having the translucent film 8 and the reflection film 3 is tilt measured at every film.

Title: Electrophotographic photoreceptor and electrophotographic device
Inventor: HIRANO HIDETOSHI
IPC: G03G5/05
Filed: 1994-03-25
Abstract: PURPOSE:To keep a sufficient film strength while improving the lubricity and wear resistance, to improve the solvent crack property and to facilitate the production by incorporating a specific polymer on the surface layer of a photoreceptor. CONSTITUTION:In the electrophotographic photoreceptor having the photosensitive layer on a conductive supporting body, a polymer having a structural unit expressed by the formula is incorporated in the surface layer of the photoreceptor. In the formula, each of R1-R8 represents hydrogen atom, a halogen atom or a 1-4C alkoxyl group or alkenyl group, each of R9-R14 is a (substituted) 1-3C alkyl group or an aryl group and (m) represents an integer of 1-200. The electrophotographic photoreceptor has particularly excellent solvent crack resistance surface lubricity and preservation stability and the reason is that the intrusion speed of a chemical causing the solvent crack is decreased by introducing the structural unit expressed by the formula into the polymer to lower the free energy of the surface.
