Title: Image forming method
Inventor: YOSHIHARA YOSHIYUKI
IPC: G03G5/147
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To always and stably obtain a high image quality by preventing soiling of a surface of an electrophotographic sensitive body due to direct electrification and a cleanerless process and blurring and streaking of an image caused by it. SOLUTION: In this method, image formation is carried out including an electrifying process where electrification of an electrophotographic sensitive body is carried out by direct injection of charge by having magnetic particles impressed with voltage brought into contact with it, a developing process where developing is carried out with toner containing inorganic particles and a process where residue toner on the electrophotographic sensitive body surface after a transfer process is recovered in the developing process. In this case, a surface layer of the electrophotographic sensitive body is a charge injected layer with volume resistivity of 1×1010 to 1×1014 Ω.cm and abrasion loss of the surface layer is 0.2 to 1.0 μm for every 100,000 rotations of the electrophotographic sensitive body.

Title: Production of ceramic sintered compact
Inventor: KUWABARA MITSUO
IPC: C04B35/622
Filed: 1989-05-26
Abstract: PURPOSE:To obtain a high-strength ceramic calcined compact having a high toughness by passing a formed body prepared by mixing a powdery ceramic raw material with a binder and sintering assistant through a specific dipping step and then sintering the resultant formed body. CONSTITUTION:A formed body prepared by mixing a powdery raw material with a binder and sintering assistant is sintered to provide a ceramic sintered compact. In the process, the following steps are carried out. That is the first step for dipping the aforementioned formed body of a calcined compact obtained by calcining the aforementioned formed body in a solution capable of dissolving an additive and the second step for dipping the abovementioned formed body or calcined compact in a solution containing soluble metal salts dissolved therein. Parts with a high concentration of the additive, such as the sintering assistant, are diluted by the aforementioned first step and parts with a low concentration are conversely increased to homogenize the whole. The grain growth rate is equalized in sintering to suppress disadvantages, such as abnormal grain growth, etc. Furthermore, the impregnated substance in the solvent can be deposited in the form of a metal or the metal surface converted into a ceramic in grain boundaries and voids in vicinity thereof after sintering by the second step and stress relaxation is promoted to enhance the toughness thereof.

Abstract: PURPOSE:To provide a dispersed EL element having uniform high luminance emission by constituting an insulating layer from a fibrous titanic acid alkali earth metal and an organic binder having a high dielectric constant. CONSTITUTION:An insulating layer is formed of a fibrous titanic acid alkali earth metal and an organic binder having a high dielectric constant. As alkali earth metals are preferably used fibrous titanic acid alkali earth metals shown by the general formula MO.nTi2 (M is an alkali earth metal, n=1-12), which are obtained by depositing carbonates of alkali earth metals on the surface of fibrous titania compounds by solution reaction and conducting heating treatment at 500-1300 deg.C. As the forms of the alkali earth metals, those having fiber lengths of 3-1000mum and fiber diameters of 0.1-10mum are used.

Title: Retinal camera
Inventor: OTSUKA HIROYUKI
IPC: A61B3/14
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To attain suitability judgement not depending on an alignment index, by controlling the focus based on the light intercepting output of a light intercepting means to intercept the retinal reflection light of the focus index placed at an almost conjugated position with the eye ground and judging the suitability of the alignment based on the intercepting output. SOLUTION: An alignment judging means is equipped in a focus controlling means Q3 and whether the optical axis of an imaging optical system is aligned with the optical axis of the tested eye or not is judged based on levels of the quantity of light of slit image signals S1 , S2 from the light intercepting means 12. That is, when the optical axis of the imaging optical system and that of the tested eye are shifted, one peak quantity level of L1 or L2 of light of focus indexes S1 , S2 is lowered since focus indexes S1 , S2 are shifted from the symmetrical positions bordered on the center of the pupil and eclipsed by the iris. Accordingly, when the ratio of peak levels L1 , L2 of quantity of light are shifted, for instance, by about 20%, the alignment is judged to be shifted to right or left and the result is displayed on a monitor 13.

Abstract: PURPOSE:To correctly detect the smoking of a spark plug by detecting the voltage-divided secondary voltage (spark electric discharge) wave shape for ignition and comparing the width of the voltage over a set level among the wave shapes with a reference voltage. CONSTITUTION:In a voltage divider 5, a sensor consisting of an electric conductor is used as high impedance element 51, and a condensor is used as a low impedance element 52, and the secondary voltage generated in a secondary circuit 12 is voltage-divided into about 1/3000.

Filed: 1983-07-22
Abstract: PURPOSE:To obtain a tracking error signal through simple constitution by selecting two kinds of pilot signals different in frequency obtained from a pilot signal generating circuit alternately through a switch circuit at intervals of recording tracks, and extracting the two kinds of pilot signals which leak into the output of a magnetic head which scans on a track where no pilot signal is recorded during reproduction through a narrow band-pass filter circuit, etc. CONSTITUTION:If a Y head 401 and a C head 402 deviate from tracks 404 and 405 to be reproduced in scanning, the signal component of frequency f1 increases in the reproduction output of the Y head, and when deviating upward, the signal component of frequency f2 increases. When the 2nd field is reproduced, the upward deviation of a rotary head from a track 403 to be reproduced increases the signal component of frequency f2 in the reproduction output of the Y head and the downward deviation increases the signal component of frequency f1. Thus, the signals components of frequencies f1 and f2 are only detected to know the extent and direction of a tracking error.
