Title: Discharged toner recovering device
Inventor: ONO KENZO
IPC: G03G21/10
Filed: 1991-07-31
Abstract: PURPOSE:To obtain a discharged toner recovering device in which discharged toner is prevented from spilling and spouting and which is convenient for handling by composing the device of a recovering container and a supporting body provided with an engaging part which supports the mouth part of the recovering container. CONSTITUTION:The recovering container 1 is provided with the rigid container mouth part 6 having a toner introducing port 5 in the upper center. An engaging recessed part 7 is provided in a circumferential direction in the nearly center of the outer periphery of the mouth part 6, and a flange-like projection 8 which projects on the upper part of the recessed part 7 is formed. The recessed part 7 is engaged with the grip 16 of the supporting body 11 so that the container 1 is supported. Therefore, the recovering container 1 is moved to discard the discharged toner without directly touching the container 1 itself with hands by holding the supporting body 11. Thus, the discharged toner recovering device in which the spilling and the spouting of the discharged toner are avoided and which is convenient for handling is obtained.

Title: Production of tetracalcium phosphate
Inventor: WAKANA MINORU
IPC: A61K6/838
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To produce high purity tetracalcium phosphate with a comparatively simple process by heating an aqueous suspension of equimolar powdery CaHPO4 .2H2 O and fine powder CaCO3 to a specified temp., maintaining the suspension at this temp. to form a reaction product and calcining the reaction product. SOLUTION: In this production, powder CaHPO4 .2H2 O and fine powder CaCO3 are mixed together in a molar ratio of 1:1 to form an aqueous suspension and thereafter, the resulting suspension is heated to a temp. above 70 deg.C and maintained at this temp. to allow it to react to form a reaction product and then, the reaction product is calcined to produce the objective tetracalcium phosphate. As the CaCO3 used, it is required to use particles as fine as possible. When the particle size of CaCO3 is large, the reaction proceeds insufficiently at a temp. above 70 deg.C and unreacted powdery CaCO3 , remains in the reaction product. From this viewpoint, CaCO3 fine particles having a <=5μm average particle size are preferred as the fine powder CaCO3 .

IPC: H04N1/407
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To control the correcting operation of both of the short-term fluctuation of image density and gradation reproducibility caused by environmental fluctuation and the like and the long-term fluctuation thereof caused by the endurance fluctuation of a photoreceptor, developer and the like. SOLUTION: By first density and gradation control operation, a prescribed pattern is formed on a recording material through a visible image forming process. Based on the density value of the formed pattern, contrast potential and a look-up table(LUT) for γ conversion are set. Then, second density and gradation control operation is executed by controlling the replenishment quantity of toner based on a first reference value 2151. The first reference value is corrected based on difference between the density value of the pattern formed on a photoreceptor drum 121 and a second reference value. By executing the visible image forming process based on a parameter set by the first density and gradation control operation, the pattern is formed on the drum 121. Based on the density value of the pattern, the first and the second reference values are corrected.

Title: Image forming device
Inventor: KAI SO
IPC: G03G15/08
Filed: 1994-08-17
Abstract: PURPOSE: To reduce the number of parts, to enhance gap or bite accuracy while restraining the rise of cost, and to accurately maintain plural gaps or the bite to a cylindrical image carrier by providing a multistage flange for positioning at both ends of the cylindrical image carrier. CONSTITUTION: A photoreceptor 1 is constituted of a drum main body 51 and positioning members 52 fitted on both ends of the main body 51.

A deformation operation executed for a character picture is recorded in the character picture in the displayed picture, and the recording can be reproduced and deformed. At the time of picking up the desired graphic, the position of a pointer on a bit map which is held in accordance with the graphic is judged. Thus, the position of the pointer can be decided and picked up without troublesome calculation even if the graphic is complicated.

IPC: G11B5/84
Filed: 1990-07-20
Abstract: PURPOSE:To suppress the curl of a magnetic recording medium by forming a thin ferromagnetic metallic film layer on a base body, afterwards, letting either the rear of the base body or the front surface of the thin ferromagnetic metallic film layer get contact with a heated heat roll and simultaneously, blowing hot air to the other side. CONSTITUTION:A magnetic recording medium original roll 2 supplied from a supplying roll 1 is guided through a guide roll 3 to a heat processor 4. One face of the magnetic recording medium original roll 2 gets contact in each heat roll 5 and simultaneously the hot air is blown from respective nozzles 6, which are arranged just above these respective heat rolls 5, to the other face of the magnetic recording medium original roll 2 so as to execute a heating processing. Then, the roll 2 is taken up through a guide roll 7 to a take-up roll 8. The magnetic recording medium original roll 2 forming the thin ferromagnetic metallic film layer on the base body is subjected to the heat processing from both front and rear sides while travelling through the heat treating device 4 and sufficiently removes internal residual stress generated on the thin ferromagnetic metallic film layer by the radiation heat of molten metal having a high melting point or the energy of evaporated metallic grains, etc., in the case of vacuum disposition, etc. Thus, the curl is suppressed.

Abstract: PURPOSE:To equally rotationally accept all interruptions by providing a logic circuit which temporarily sets an interrupt output signal to the interrupt non- request state when interrupt request signals are rotationally accepted once with the interrupt output signal in the interrupt request state. CONSTITUTION:A slave circuit 2 is provided with a logic circuit which outputs OR among plural interrupt input signals as an interrupt output signal 16 to a master circuit 1. The logic circuit is provided which temporarily sets the interrupt output signal 16 to the interrupt non-request state when interrupt input signals 12 to 15 are rotationally accepted once with the interrupt output signal 16 in the interrupt request state. When accepting an interrupt request from a slave circuit 2, the master circuit 1 stops rotational acceptance of interrupt input signals 9 to 11 and accepts the interrupt request of the interrupt output signal 16 from the slave circuit 2. Thereafter, rotational acceptance in the master circuit is restarted when interrupt input signals are rotationally accepted once in the slave circuit 2. Thus, all interruptions are accepted equally rotationally.
