Title: Image forming device
Inventor: YAMAKAWA KENJI
IPC: G03G21/00
Filed: 1987-09-29
Abstract: PURPOSE:To prevent the early destruction of the surface of an image carrier drum by making a press-contacting power of the end part area of at least one processing member which abuts on the image carrier drum to the part of the image carrier drum facing said part weaker than the press-contacting power of other part of the processing member to the part of the image carrier drum facing said part. CONSTITUTION:The electric layer part 3a of the part of a photosensitive drum 35 and its neighboring part 36 facing the end part area 32 of a cleaning blade 15 is more softly formed and more easily deformed than the elastic layer part 3b in other part of the photosensitive body in a circumference direction. Therefore, the press-contacting power of the end part area 32 of the cleaning blade 15 which abuts on the photosensitive drum 1 to the part 35 of the photosensitive drum facing it is made weaker than that of other part cleaning blade, that means, the central part 34 in the longitudinal direction of the blade, to the part of the photosensitive body facing it. Thus, excessive stress does not occur on the outer layer part of the part of the photosensitive drum facing the leading edge part 33 of the blade 15 and the early destruction in this part can be prevented.

Title: Inspection of content in packaged body
Inventor: NAGATA MASANORI
IPC: G01V1/00
Filed: 1986-10-15
Abstract: PURPOSE:To generate no gas and enable even an opeque packaged body to be totally inspected by passing an ultrasonic through the packaged body and observing detection values in order to judge the presence or absence and the degree of the deterioration of packaged content. CONSTITUTION:A distance between an ultrasonic wave transmitter 2 and an ultrasonic receiver 3 is made constant and an ultrasonic wave with a given frequency is transmitted from the transmitter 2. The ultrasonic wave passing a packaged body which is packed with contents and enclosed in a packaging material is received by the receiver 3. The sound velocity or the damped amount of the received ultrasonic wave is detected by a propagation time detecting circuit 9, a propagation damping detecting circuit 8 and arithmetic circuit 10. At this time, some frequencies of the ultrasonic wave are selected and an optimum frequency suitable for an inspection purpose is determined. Thus, no gas is generated and the deterioration, including its degree, of the content in an opaque packaged body can be totally inspected on line and in non-destructive manner.

IPC: B23K26/00
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To embody safety at a low cost by providing a laser beam machine with a controller which detects the function failure of an optical fiber unit of a laser beam machine and controls this optical fiber unit to stop the emission of a laser beam. SOLUTION: A controller 15 controls the emission of the laser beam from a laser oscillator 11 according to the energization state between both units 12 and 14 via connecting parts 18 and an electric wire 19 by detecting the voltage impressed between the casing 16 of an incident unit 12 and the casing 20 of a processing unit 14. The energization state between the incident unit 12 and the processing unit 14 is interrupted in the event of the function failure of the optical fiber unit 13. The controller 15 detecting this non-energization state stops the emission of the laser beam by the laser oscillator 11 and, therefore, the safety of the laser beam machine 10 is assured.  The casing 16, the casing 20 and the connecting parts 18 are composed of conductive materials and both connecting parts 18 are merely connected by the electric wire 19 and, therefore, the function failure of the optical fiber unit 13 is detected at a low cost without the need for using the intricate mechanisms.

The integration is executed by welding, etc. In the outer rice-cooking pot 2, a low frequency electromagnetic induction heating part 3 is provided. As for the electromagnetic induction heating part 3, it is desirable to provide it on the lower part of the outer rice-cooking pot 2, because the inner rice-cooking pot 1 is heated through a thermal medium. Between the inner rice-cooking pot 1 and the outer rice-cooking pot 2, the thermal medium 4 is filled in. As for the thermal medium, silicone oil, mineral oil, edible oil, etc., can be used, but it is desirable to use edible oil such as 'tempura' (fried food) oil, etc., by reason of sanitation and safety. In the case 'tempura' oil is used, it is desirable to hold a vacuum between the inner rice-cooking pot 1 and the outer rice-cooking pot 2, and to fill its part with 'tempura' oil in order to prevent oxidation.

Abstract: PROBLEM TO BE SOLVED: To obtain a high-density and large-sized ITO sintered compact with no density unevenness by designing the respective particle sizes of indium oxide powder and tin oxide powder in a feedstock slurry and the pH of the slurry to be within respective specific ranges. SOLUTION: This ITO sintered compact is obtained by designing the respective particle sizes of indium oxide powder and tin oxide ponder in a feedstock slurry to be <=0.8 μm and the pH of the slurry to be >=8.0; wherein if the above particle sizes exceed 0.8 μm, the particles become subject to sedimentation in the slurry, leading to being subject to the density unevenness in a molded form obtained by cast molding of the slurry; and if the pH of the slurry is <8.0, the particles in the slurry become subject to mutual flocculation, leading to forming a molded form through the mutual impression of particles flocculated during the cast molding, therefore decreasing the density of the resultant molded form.  Furthermore, by conducting a vacuum defoaming treatment prior to the slurry cast molding or by adding a defoaming agent to a dispersion medium for the slurry, a high-density molded form is obtained through reducing cells contained therein.

Filed: 1983-12-28
Abstract: PURPOSE:To accurately calculate the optimum value of the time constant of a speed control system by sampling the output of a period measuring circuit after the lapse of time of 1/4 of the set value from when the output of the measuring circuit becomes equal to the set value. CONSTITUTION:When a sinusoidal speed command Nref is outputted, a motor 13 rotates at a speed Nref. At this time, the period tau of the output of a resolver 14 excited by a frequency f0 is obtained by a zero cross interval counter 16. A microcomputer 11' calculates the speed N of the motor 13 from the period tau. A comparator 17 outputs a drive signal when the period tau becomes equal to the period tau0 corresponding to the speed 0 of the motor 13. A timer 18 outputs an interrupt signal when 1/4 of period is elapsed from the variation in the speed from when a drive signal is applied. A microcomputer 11' calculates the speed N of the motor 13 by an interrupt signal, and the time constant of the speed control system is calculated by the value being obtained.
