Title: Method for controlling surface potential
Inventor: KOBASHI SADANORI
IPC: G03G15/00
Filed: 1990-11-30
Abstract: PURPOSE:To maintain uniform surface potential of a photosensitive film by adding or subtracting the voltage difference between the drum cap voltage and the maximum value of measured surface potential of the photosensitive layer to or from the voltage applied on a grid of an electrifier when the max. of the surface potential of the photosnensitive layer measured is equal to or larger than the lower limit. CONSTITUTION:The lower limit is determined from the calculation of a processer 13 using the potential of drum cap 6 measured as the referential value, and the obtd. limit is stored in a storing means 12. Then the surface potential of the photosensitive film 1 is detected by a potential sensor 7, and when the max. at the measuring potential is equal to or larger than the lower limit, information is transferred from a processer 13 in a digital signal form to a high voltage power source 11 to change the voltage to be applied on a grid 9 of scorotron electrifier 8. To change voltage on the grid, the max. of the surface potential on the photosensitive film 1 measured in a certain period for one turn of the photosensitive drum is compared to the referential value determined by the voltage on the drum cap 6 to obtain the differential, and then this differential is added to or subtracted from the voltage applied on the grid 9 of the electrifier. Thus, the surface potential of the photosensitive film 1 is maintained constant.

IPC: H01M10/05
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To improve cyclic characteristics and high-efficiency discharge characteristics by containing LiCoO2 as an active substance, and comprising a positive electrode plate in which a ratio of respective X-ray diffraction peak strengths on (003) and (104) faces is within a specific range. SOLUTION: A positive electrode plate is fabricated as follows. A paste consisting of LiCoO2 , a conducting agent, a bonding agent, and a solvent is coated on an Al foil, and rolling is carried out after drying. Rolling is carried out so that the strength ratio I(003)/I(104) of a diffraction peak strength I(003) of a (003) face at an angel of 2 θ=18.5±0.5 degrees measured by X-ray with CuK α being a radiation source and a diffraction peak strength I(104) of a (104) face at an angle of 2 θ=44.5±1.0 degrees is 2 more and less than 5 by using a roller type rolling machine, and then, the paste is cut to a proper size to make a positive electrode plate. When this strength ratio is 5 or more, orientation on the (003) face of the electrode plate itself becomes strong, and therefore, ion diffusion is prevented.  When the strength ratio is less than 2, a conduction network in the electrode plate is demolished by swelling and contraction sue to charging and discharging.

Title: Optical head
Inventor: MATSUBARA AKIRA
IPC: G11B7/125
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a compact, thin optical head by changing the optical axis of the light emitted from a semiconductor laser into the direction of the optical axis of an objective lens with a light-amount separating means, and arranging a photodetector on an optical substrate at a position facing the objective lens with the light-amount separating means in-between. CONSTITUTION:A part of the amount of laser light emitted from a semiconductor laser 11 is reflected from a half mirror 12 which is inclined by about 45 degrees with respect to the optical axis. The reflected light is directed toward the direction of the optical axis of an objective lens 13 and reflected from an optical disk. The light is modulated by the amount of light with the pits of the optical disk. The light is cast into the objective lens 13 again and returned into the half mirror 12. A part of the light is transmitted and cast into a photodetector 14 which is attached on an optical substrate 10. Since the optical axis is changed with the half mirror 12 in this way, optical parts such as a rise-up mirror are not required. The photodetector 14 can be directly arranged laterally on the optical substrate in parallel with the objective lens 13. Therefore, the number of the parts can be decreased, and the optical head can be made compact and thin.
