Title: Illumination light source device
Inventor: MOCHIZUKI AKIHITO
IPC: H05B37/02
Filed: 1986-06-19
Abstract: PURPOSE:To obtain the stable necessary quantity of light and to improve excitation characteristics of an illumination light source by providing a means which heats the illumination light source by a PTC heat generating body, a means which detects the temperature variation of the PTC heat generating body from the resistance variation of the heat generating body, and a means which controls the load voltage of the PTC heat generating body. CONSTITUTION:When the (Positive Temperature Coefficient) PTC heat generating body 11 with a positive resistance temperature coefficient is lower than set temperature, namely, when the resistance value of the PTC heat generating body 11 is smaller than the set resistance value of a resistor 12, the load voltage of the PTC heat generating body 11 is increased and when the resistance value of the PTC heat generating body 11 exceeds the set resistance value of the resistor 12, on the other hand, the load voltage is lowered. For the purpose, a comparator 15 outputs a switching signal (a) to a changeover switch circuit 16. The load voltages V1 and V2 of the PTC heat generating body 11 are therefore switched to hold the heating value (surface temperature) of the PTC heat generating body 11 constant. The surface temperature of the PTC heat generating body 11 is balanced with the tube wall of a fluorescent tube, so the tube wall temperature of the fluorescent tube is also held constant.

Title: Noise reducing device for image
Inventor: OYAMADA MASAKAZU
IPC: H04N1/409
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To reduce noises from a two-level image composed of black and white pixels. SOLUTION: In this noise reducing device, noises mixed into a double gradation image composed of black and white pixels are reduced by performing the reloading processing of relevant obkect pixel while successively defining the pixels in the relevant image as the object pixel. Concerning an area composed of plural surrounding pixels including the object pixel, a density calculating means 32 calculates the density of black pixels or white pixels at least and when the density of white pixels is higher than prescribed reference density, based on the calculated result, a pixel replacing means 33 replaces the relevant object pixel with a white pixel. Thus, when a lot of white pixels exist around, by replacing the relevant object pixel with a white pixel, a noise component to appear at a blank section in a document as a black spot, for example, is removed.

Title: Molten metal pouring device
Inventor: MURAKAMI MANABU
IPC: B22D41/06
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a molten metal pouring device which can improve the measuring accuracy in a simple and inexpensive structure and can introduce the accurate quantity of the molten metal into a metallic mold for casting. SOLUTION: At the time of introducing the molten metal in a ladle 16 into the metallic mold for casting, the center position of gravity is shifted in the arrow mark A' direction according to the shifting of the molten metal in the ladle 16, but since the shifting direction of the center position of gravity is parallel to the extending direction of the axial member 28, a moment given to a load cell 20 is varied only with the weight of the molten metal and does not depend on the center position of gravity. Therefore, the measuring error of the molten metal based on the shift of the center position of gravity is not generated, and the accurate quantity of the molten metal into the metallic mold for casting can be introduced.

Title: Cleaning device
Inventor: NAKAMURA MASAHIRO
IPC: G03G21/00
Filed: 1981-09-11
Abstract: PURPOSE:To obtain a small-sized cleaning device while eliminating toner filming, and to improve its durability, by utilizing a viscous liquid. CONSTITUTION:A cleaning roller 9 is arranged between a viscous liquid holding roller 3, dipped in a visous liquid 4 having 10<1>-10<5> cps viscosity, and a photoconductor 1 with residual toner T0. Then, when the photoconductor 1 is fed as shown by an arrow between a back roller and the cleaning roller 9, a viscous liquid 4a applied in a thin film around the roller 3 comes into contact with the cleaning roller 9 to dislocate toner T1 from the cleaning roller 9 by viscosity, and the viscous liquid 4a containing the dislocated toner T2 is peeled off and collected from the roller 3 with a doctor knife 7. Since no fur brush is used, toner filming due to friction heating never occurs. Fuuther, an endless belt 13 is usable instead of the roller 3.
