Title: Electrophotographic sensitive body
Inventor: TAMAHASHI KUNIHIRO
IPC: G03G5/08
Filed: 1988-08-18
Abstract: PURPOSE:To improve the hardness and moisture resistance of a protective film by forming the protective film constituted by dispersing gamma type aluminum oxide into an amorphous carbon fluoride film on the surface of a photoconductive layer. CONSTITUTION:The protective film is formed by dispersing the gamma type aluminum oxide having high hardness into the amorphous carbon fluoride film having excellent moisture resistance and corona property. Although the amorphous carbon fluoride film is higher in moisture resistance than the gamma type aluminum oxide, the Mohs' hardness thereof is 2.5 which is smaller than 6.5 Mohs' hardness of the gamma type aluminum oxide. The protective film is, thereupon, formed by dispersing the gamma type aluminum oxide having the high Mohs' hardness into the amorphous carbon fluoride film having the good moisture resistance. The hardness and moisture resistance of the protective film are improved in this way.

IPC: B21D24/04
Filed: 1986-09-01
Abstract: PURPOSE:To enable the title method to mold even a stepped molded product and deep-draw molded product by one process, by a method wherein at the time of draw molding though pressing, along with formation of a bead on a circumferential part of a material in the course of molding a rising wall surface to be formed on the material is pressed. CONSTITUTION:A cam surface on the other end side of a passive cam 12 and a cam surface 15a of a draw bead member 15 are slided each other through a movement of the passive cam 12 and a bead S2 is formed on an outer circumferential part S1 of a material S by ejecting a draw bead member 15 upward through a bottom force 8. Tension from an external circumferential part side of the material S is controlled by molding of the bead S2. On the one hand, a pressing tool 16 is ejected into a cavity 13 by a spring member 17 and presses against a rising wall S3 of the material S to which draw molding has been kept performing with a punch 10. As the tension of the rising wall S3 of the material S is controlled in the course of the molding like this, generation of creases on the rising wall S3 is prevented. Therefore, even a stepped molded product and deep-draw molded product can be molded by one process.

Title: Interval-timer photographing device
Inventor: WAKABAYASHI TSUTOMU
IPC: G03B17/40
Filed: 1988-08-19
Abstract: PURPOSE:To surely prevent a malfunction which usually occurs in such a state where no photographing can be made due to a non-focusing state on a camera main body side by stopping the output of a release signal until the next interval time when no imprinting signal is inputted during the lapse of fixed time even when the terminating end of a roll of film does not come. CONSTITUTION:A signal indicating the terminating end of a roll of film is inputted from a camera main body 201 and an interval timer photographing device 101 is stopped when the terminating end of a roll of film is detected. Therefore, when an imprinting signal I2 is not inputted during a prescribed time of, for example, 10 seconds and no photographing is made by the camera main body 201 after a release signal O1 is outputted, the output of the release signal O1 is stopped until the next interval time, since the reason why no photographing is made is not due to the terminating end of a roll of film, but due to no focusing state is set or the like. Therefore, such a malfunction that stops the following interval timer photographing due to the non-focusing state on the camera main body side can be prevented surely.

Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a rotation detector which detects absolute angle of a rotating body with high resolution, with longer life and lower constitution cost, even when the rotating body rotates a plurality of times. SOLUTION: On a rotating body 15, multiple magnetic members 16 are provided concentrically with a steering shaft 14 at a specified pitch, and a magnetic sensor 18 which moves in axial direction according to rotation of the rotating body 15 is also provided. When the rotating body 15 rotates, the magnetic member 16 faces intermittently the magnetic sensor 18, so that the value of voltage signal outputted from the magnetic sensor 18 according to the distance from the magnetic member 16 becomes larger intermittently. By detecting the number of times when the voltage signal becomes larger when the rotating body 15 rotates several times, the rotation angle of the rotating body 15 is detected, and by detecting increase/decrease change of the value when the voltage signal becomes larger, rotation direction is detected.  Here, by detecting the magnitude of the value of voltage signal from the magnetic sensor 18 when it becomes larger, the absolute angle of the rotating body 15 is detected with high resolution.

The distance (h) is always controlled so as to be kept within the prescribed range during crystal growth. Thereby, it is prevented that the temperature gradient within crystal becomes smaller, and the longer single crystal can be grown.

Abstract: PURPOSE: To obtain a toner for electrophotograph capable of attaining high resolution while maintaining satisfactory image density and having high flowability by incorporating fine hydrophobic silica powder having a specified average particle diameter into a toner contg. a specified amt. of powder having a specified particle diameter. CONSTITUTION: Inorg. fine powder having <=20nm average particle diameter is incorporated into a toner contg. 1 to 5vol.% powder having <=5μm particle diameter and the median particle diameter of the toner is regulated to 8 to 12μm. The flowability of the toner deteriorates because fine toner particles are contained. In order to prevent the deterioration, the inorg. fine powder is incorporated into the toner. The inorg. fine powder controls the electrostatic charge of the toner as incidental action. Fine hydrophobic silica powder is especially preferable as the inorg. fine powder because it, is excellent in environmental resistance, improves the flowability of the toner and also contributes to the electrostatic charge stability of the toner. Fine powder of titanium oxide or aluminum oxide may be used as an inorg. fine powder.
