Title: High-density scanning device
Inventor: TAKANASHI KENICHI
IPC: G02B26/12
Filed: 1989-07-21
Abstract: PURPOSE:To eliminate the shifting of a light beam and to eliminate the curvature of a scanning line by providing one transparent parallel flat plate rotatably in the optical path extending from a 1st image formation optical system to a 2nd image formation optical system through a rotary polygon mirror. CONSTITUTION:The plate thickness of the parallel flat plate 8 is denoted as (d), the refractive index as (n), the normal of the parallel flat plate 8 as 8N, luminous flux incident on the parallel flat plate 8 as mu, the tilt angle of the incident luminous flux mu as (u), the incidence point as A, and the projection point as B. Here, when the luminous flux mu slants to the normal 8N and is incident on the parallel flat plate at the point A, the luminous flux mu is emitted from the point B shifting by  y in a subscanning direction. Then  y is represented as a function of (d), (n), and (u). Consequently, the optical axis can be moved in the subscanning direction by providing one transparent parallel flat plate rotatably in the optical path extending from the 1st image formation optical system to the 2nd image formation optical system through the rotary polygon mirror.

Title: Fixing device for electrophotography
Inventor: SUZUKI TAKASHI
IPC: G03G15/20
Filed: 1989-07-21
Abstract: PURPOSE:To save wasteful electric power, to provide the consumption of a heater caused by overheat and to reduce power rates and maintenance cost by providing plural sheathed heaters in a longitudinal direction in a preheater corresponding to the width of a printing paper so that they may be alternate on both sides at the time of viewing from the above. CONSTITUTION:A material having excellent thermal conduction such as aluminum is used for the preheating plate 15 of a fixing device, where the sheathed heaters 16a-16d are juxtaposed in the longitudinal direction of the preheating plate 15 and arranged so that heating parts may be alternate on both sides at the time of viewing from the above. When the respective heaters are energized to heat the narrow paper 6A, for example, in such a state, a temperature below a heating part 18 lowers because the heat is absorbed by the paper and the resistance values of thermistors 17a and 17b are changed. In such case, the resistance values of the thermistors 17c and 17d are not changed. By utilizing the change of the resistance values of the thermistors and controlling the on/off of the current of the heater, the paper is heated at the same temperature whether the width of paper is wide or narrow.

Title: Optical coupling structure and its production
Inventor: KITAMURA NAOKI
IPC: G02B6/24
Filed: 1993-07-30
Abstract: PURPOSE:To simultaneously couple an optical waveguide and an optical fiber with high efficiency without requiring intricate process by loading a thin film which is easily dissolved in an anisotropic etching liquid in a part near the end face of the waveguide on a substrate and removing this thin film at the time of forming a V-groove by anisotropic etching of the substrate. CONSTITUTION:The thin film 2 of the material which is easily dissolved by anisotropic etching is loaded on the substrate 1 in the part near the end face of the waveguide and thereafter, the waveguide is formed. The thin film 2 is dissolved at the time of forming the V-groove by the anisotropic etching and the surface of the substrate 1 of the part where the thin film 2 is loaded is also subjected to the anisotropic etching. The thin film 2 loaded in the part near the end face of the waveguide is first etched in such a manner and, therefore, even the substrate 1 in the lower part near the end face of the waveguide is subjected to the anisotropic etching as well. The (111) face 11 exposed by the conventional anisotropic etching is exposed on the side inner than the end face of the waveguide by this etching and, therefore, this face does not give any hindrances to coupling with the optical fiber at all.

Filed: 1982-10-29
Abstract: PURPOSE:To enable a higher detection accuracy by inserting a thin band into a part between a lid member and an amorphous magnetic alloy except for that corresponding to an opening of a pot-shaped soft magnetic member. CONSTITUTION:A thin band 8 is inserted between an amorphous magnetic alloy 4 and a lid member 5, specifically at least a part except for that corresponding to an opening 2a of a pot-shaped magnetic alloy 2. In the embodyment, it is provided as a ring-shaped thin band 8 along the outside of an O ring 6 mounted section. The thin band 8 is deformed so much according to convexes and concaves existing on the undersurface of the lid member 5 and the surface of the amorphous magnetic alloy 4 that they will contact each other satisfactorily. This prevents the skidding of the amorphous magnetic alloy 4 with respect to the lid member 5. The deformation of the thin band 8 eliminates uneven fixation to ensure that the amorphous magnetic alloy 4 is fastened securely.
