IPC: G03G15/16
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To collect the secondary transcribing residual toner from upon an intermediate transcription drum in good performance using a photo-sensitive drum. SOLUTION: The polarity of a secondary transcribing residual toner 10 on an intermediate transcription drum 5 is inverted by a cleaning bias impression roller 7a so that a secondary transcribing residual toner 11 is prepared, and a primary transcription bias is impressed on the drum 5 from the primary power supply, and the secondary transcribing residual toner 11 is inversively transcribed on a photo-sensitive drum 1 parallel with the primary transcription of the toner image on the photo-sensitive drum 1.  At this time, the primary transcription bias is set as smaller than the upper limit of the potential difference with which the secondary transcribing residual toner 11 can be collected to the dark part with the darkess potential VD on the photo-sensitive drum 1 and larger than the lower limit capable of being collected to the light part with the lightness potential VL on the photo-sensitive drum 1. Thereby the secondary transcribing residual toner on the intermediate transcription drum drum 5 can be collected from the whole region of the surface of the photo-sensitive drum 1.

Title: Floating point number arithmetic unit
Inventor: IDE YUKIHIRO
IPC: G06F7/508
Filed: 1989-11-30
Abstract: PURPOSE:To reduce the number of transportation times for a carry in a mantissa part so as to speed up an addition/subtraction processing by previously judging a rounding processing and simultaneously executing the arithmetic processing and the rounding processing of the mantissa part in accordance with the judgement result. CONSTITUTION:A rounding foresight circuit 7 receives respective lower five bits of the prescribed mantissa parts M5a and M5c, which are given from a selection circuit 5, a size comparison signal given from an exponential part comparison circuit 1, an addition/subtraction control signal, a rounding mode signal and the code of a first operand and previously judges whether the rounding processing is to be executed by the signals or not before an operation. Then, the judgement result is given to adders 8a and 8b as a rounding judgment signal, and the adders 8a and 8b calculate a solution including the rounding processing in the addition or subtraction in the mantissa part of first and second operands. Thus, the number of the transportation times of the carry in the operation process of the mantissa part is reduced and the addition/subtraction processing is speeded up.

Title: Power supply controller
Inventor: OGAWA TAKAHIRO
IPC: H04N5/63
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To cut off power supply based on generation of failure in a secondary circuit and a command from a microcomputer. SOLUTION: A switch is interposed between a primary circuit and an AC power supply to make the switch cut off electric power from the AC power supply with a power off signal which a secondary circuit outputs. It is thus possible to cut off main power supply completely automatically in case of some failure, or in the case of remote operation by a user or use of a sleep timer.

Title: Developing device, process cartridge and electrophotographic image forming device
Inventor: YAMAGUCHI SEISHI
IPC: G03G15/08
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To achieve a reduction in the number of occurrences of coarse toner particles and the prevention of an image failure, such as vertical white streak, by freely rotatably supporting the journal of a stirring member, which is on the undrivable side, further inside than the front end of the stirring member, which is on the undrivable side. SOLUTION: In the side wall 3c of a toner storage container, on the undrivable side, a bearing hole 8 of a cylindrical shape is made. The bearing hole 8 consists of a support portion 8a for the stirring rod 7, and a recessed portion 8b so formed as to prevent friction between the internal wall of the bearing hole 8 and the front end 7a1 of the stirring rod 7. Because the stirring rod 7 is supported in a narrower area by making the size of the support portion 8a smaller than that of the conventional structure, the number of occurrences of coarse toner particles can be reduced. Further, even in case the stirring rod 7 plays in its longitudinal direction, the structure in which the support portion 8a is disposed further inside than the end of the stirring rod 7 prevents the drop out of the stirring rod 7 by making the length of the recessed portion 8b greater than the size of the play.

IPC: B65H75/36
Filed: 1986-12-23
Abstract: PURPOSE:To prevent overheating of a cable due to a resistance heat, by providing a water tank from which to feed water or in which to store water and a means, which laminates a flexible cable, bent in a 8-shape within a horizontal plane, in the water tank. CONSTITUTION:When a cable 3 is stored in a water tank 1, the cable 3 is stored in a state to be bent in a 8-shape in a horizontal plane by means of a guide means 4. Water is injected through the nozzle of a shower means 5 against the cable 3 stored. Since the injected water forced into contact with the outer periphery of the cable 3 and the water flows, the cable 3 is prevented from overheating. This constitution prevents damage of the synthetic resin sheathing layer of the cable 3, and prevents the occurrence of firing to ensure safety.

Abstract: PURPOSE:To reduce the number of constituent parts and power consumption by supporting an ice making dish in an ice making unit for automatic control of ice making and ice removal and providing a feed water pipe, to the internal wall of which water repelling treatment is applied, above the ice making dish. CONSTITUTION:A feed water pipe 10 made of plastic material, whose internal wall is coated with fluororesin to apply water repelling treatment 10a to said wall, is provided above an ice making dish 11. A predetermined amount of water is filled into the dish 11 by means of the pipe 10. In this case, since water repelling treatment has been applied to the internal wall of the pipe 10, water does not remain in the pipe 10. The dish 11 is cooled in a refrigeration chamber 5 to make ice. After completion of ice making, an ice making unit 9 rotates to turn the dish 11 about a supporting axis 11a. And the dish 11 contacts a stopper so that the dish 11 is deformed to separate the ice, thereby allowing the ice to fall down to be stored.
