Title: Image forming device
Inventor: AOIKE TATSUYUKI
IPC: G03G15/00
Filed: 1983-12-02
Abstract: PURPOSE:To perform control corresponding to an image original by detecting the quantity of exposure and discriminating whether the density contrast of the original image is high or not, switching a preset control command according to the discrimination result, and controlling the density contrast. CONSTITUTION:An original density cintrast discriminating means 2 discriminates on whether the density contrast of the original is high or low from the quantity of exposure detected by an image exposure among detector 1. A determining means 3 for the standard potential of potential control decides the standard potential used for the potential control on the basis of the discrimination result. An arithmetic means 5 for correcting data on the amount of electrostatic charging calculates the amount of correction of the amount of charging from the standard potential and a model potential detected on a photosensitive body by a surface potential detector 4. A control means 6 for the amount of charging controls the adjustment amount of an adjusting means 7 for the amount of charging on the basis of the correction amount of the amount of charging. Consequently, the density contrast of a recording image is controlled. Thus, the density contrast of the recording image is controlled corresponding to the original image and even character patterns on a low-contrast original are copied sharply, thereby reducing the deterioration of the photosensitive body.

Title: Hub mounting method and hub mounting device for optical disk
Inventor: ITO HIRONOBU
IPC: G11B7/00
Filed: 1991-09-06
Abstract: PURPOSE:To surely and easily mount a hub to an optical disk horizontally by applying an adhesive to a hub mounting part, then bringing the hub in proximity to the optical disk and blowing compressed air from a hub chucking member, thereby press-fitting and adhering the hub. CONSTITUTION:The hub 3 attracted to a hub chucking member 2 falls onto the optical disk 1 previously coated with an adhesive 10. The hub 3 attracted to the member 2 stops once on the optical disk 1 and is detached; simultaneously the compressed air is blown from a blowing hole 27 provided on the member 2. Consequently, the hub 3 is parted from the member 2 by the air pressure and is press-fitted to the optical disk 1. A pressure is applied evenly to the hub 3 when the hub 3 is press-fitted by using the compressed air and, therefore, the hub 3 can be uniformly adhered. The unequal pressing of the hub 3 is eliminated and, therefore, the distortion of the optical disk is obviated even when the attraction surface of the member 2 inclines to the optical disk 1.

Title: Single can multiple water passages type water heater equipped with filtration function
Inventor: KIMURA SHINGO
IPC: F24H1/00
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a single can multiple water passages hot water heater equipped with filtration function capable of pouring hot water supplied from a hot water supply side into a bathtub through a reheating flow passage while preventing the hot water from reversely flowing to a filtration tank and being reheated in a heat exchanger. SOLUTION: A communication pipe 70 branched from a hot water supply flow passage 30 is joined with a reheating flow passage 50 at a junction position 54 on an outlet side of a heat exchanger 13. There are disposed a filtration tank 60 and a motor driven five-way valve 80 that can close the post burning flow passage 50 located on the side of a suction inlet 101 from the junction position 54. The motor driven five-way valve 80 is closed upon hot water injection operation, whereby hot water flowing from the hot water supply flow passage 30 to the junction position 54 of the post burning flow passage 50 is prevented from flowing to the side of a suction inlet 101 but flows only to the side of the discharge outlet 102.  Since hot water is injected without again passing through the heat exchanger 13, it is eliminated the need of reducing a heating amount on the side of a combustion fan 20 taking reheating of the heat exchanger 13 into consideration so that condensation in the heat exchanger 13 is prevented. Further, hot water is prevented from reversely flowing to the filtration tank 60 upon hot water injection.

Title: Shading correcting device
Inventor: TAKATSUKI EIICHIRO
IPC: H04N1/401
Filed: 1986-09-29
Abstract: PURPOSE:To prevent the effect of dust adhered onto a reference face by selecting a maximum value at each group of N picture elements of an electric signal obtained through photoelectric conversion, storing it as a shading correc tion signal and dividing the picture signal by a shading correction signal. CONSTITUTION:Since the dust 12 on the reference face 1 has a small light reflection than that of the reference face 1, it is caught as a black picture in reading it by a CCD 4. Suppose that the width of the dust 12 is M picture elements, the value N is selected larger and nearly to the same degree as the largest dust width. In storing a shading distortion signal converted into a digital signal by an A/D converter 6 into a RAM 7, the maximum value of each N picture element is selected and stored by a maximum value selection circuit 11. The stored waveform has no effect of the dust 12. The shading distortion signal stored of the signal reading the original 9 by the method above is read from the RAM 7, divided by a divider 8 to apply shading correction without the effect of the dust 12.
