Title: Photoelectric converter
Inventor: YAMAMOTO HIDEO
IPC: H01L31/02
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a photoelectric converter which prevents the peel off of a transparent resin for sealing the gap between the photodetecting face of a photoelectric converter element and transparent substrate due to the expansion coefficient difference. SOLUTION: A photoelectric converter element 1 is flip chip bonded to a metal wiring 3 formed on the surface of a transparent substrate 2 through metal ball-made bump electrodes, and transparent resin 5 is charged in the gap between the photo detecting face of the converter element 1 and sealing face of the substrate 2, thereby sealing the gap. The metal ball of the bump electrode 4 is set to a diameter of 100 microns or more to ensure the gap of 40 microns or more between them. This relaxes the thermal stress caused by the expansion coefficient difference between the resin 5 and substrate 2 or the hardening shrinkage stress of the resin itself, thereby preventing the resin 5 from peeling up.

Title: Permanent magnet type rotor
Inventor: NOZAWA YASUTO
IPC: H02K1/27
Filed: 1992-07-22
Abstract: PURPOSE:To obtain a rotor structure which can generate a large amount of magnetic fluxes and is suitable for high-peripheral velocity operation by constituting a rotor base body of an inner cylinder section and outer cylinder section made of a soft magnetic metal and forming four or more magnetic poles by arranging magnetically integrated permanent magnets between the inner and outer cylinders. CONSTITUTION:The inner cylinder section 13 of the rotor works to reduce magnetic reluctance between each permanent magnet 11. When about 80% or more of magnetic fluxes generated from the magnets 11 is supplied to the outer peripheral part of the rotor, the magnets 11 are magnetically integrated. The outer cylinder section 12 of the rotor is positioned on a straight line passing through the centroid of the magnets 11 from the center of the rotor on a cross section perpendicular to the rotating shaft of the rotor and mechanically restrains the magnets 11. While the magnets 11 have uniform radii of curvature on its inner and outer peripheries, the movement of the magnets 11 in the peripheral direction can be restrained when, for example, their larger and smaller radii of curvature are combined. In addition, when the thickness of the magnets 11 and the shortest distance between each magnetic pole are larger, falling-off of the magnets 11 from the rotor can be prevented. In addition, when the number of the magnetic poles are increased to four or more, monopolar repulsion rotors can generate equal or more magnetic fluxes than external-magnet rotors.

Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To execute main scanning directly without performing pre-scanning concerning a designated frame by setting image reading conditions from density information related to film type information stored based on the film type information, acquiring the density information based on an image signal and updating the stored density information. SOLUTION: A CPU 1 reads out the film type of a cartridge 19 and inquires whether the density information related to a host computer 50 is stored in a memory 50b or not. When it is stored, the reading conditions are set from that density information and the photographic conditions of the designated frame, the density information is acquired from image data by performing main scanning and the density information in the memory 50b is updated. When that information is not stored, density information is acquired by performing prescanning on fixed reading conditions and stored in the memory 50b. Thus, when reading the same film type the next time, it is not necessary to perform prescanning and operability is improved.
