Patent JP-H066500-A (JP)
Title: Facsimile equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/00
Filed: 1992-06-19
Abstract: PURPOSE:To attain dual operation without increasing the equipment cost by storing received picture information to a picture storage means for transmission picture information only when the picture information is received in the picture transmission mode able to detect an error. CONSTITUTION:In the facsimile equipment having the picture transmission mode able to detect an error such as the error correction mode(ECM) at the reception of a picture in the ECM mode, a control circuit 14 has only to check a CRC code outputted from a MODEM 4 and no decoding is required. Thus, the load of the control circuit 14 is less than that at the reception of the G3 mode, and the operating rate of a CPU is reduced. Thus, a margin of parallel operation of other processing is produced, and for example, the storage of transmission information to a memory is attained. Furthermore, a signal on a signal line 6a is received and modulated in the transmission and the modulated data are outputted to a signal line 4b. Moreover, the setting of the transmission speed, and the setting of the ECM or the G3 mode are implemented through a signal line 14b.

Abstract: PURPOSE: To regenerate a filtering mateial automatically at a purification apparatus by filtering refuses etc. being contained in water with a filtering mateial, by making water flow back into a purifying tank to remove the refuses in the filtering material.  
     CONSTITUTION: A purifying tank packed with filtering material 2, a reversibly rotatable circulating pump 5, and a switch valve 6 are cnnected to a water tank 12 such as bath tub, fish farming tank by a circulating piping. In purifying wate, water containing-refuses is made to flow into the purifying tank 1 from its upper side through a circulating path 7, the switch valve 6, the 1st flow path 3, and the refuses are filtered by the material 2 in the tank 1, then the purified water is circulated through the 2nd path 4, a check valve 11 of the 3rd flow path 10 to the tank 12 by the pump 5. When the filtering capacity is lowered by the refuses deposited in the material 2, the pump 5 is reversely rotated together with switching the valve 6 to make the water flow into the tank 1 in the direction tangentially to the bottom of it from the pump 5 and the 2nd path 4, so that the refuses are separated from the material 2 while the water whirls in the tank 1; thus the material 2 is regenerated by discharging the refuses to a discharging path 8 from the valve 6.

Title: Brush device for motor
Inventor: UCHINO SETSUYA
IPC: H02K5/14
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To obtain a brush device whose insulating property with reference to the deposition of a brush powder is ensured and which saves the space of a brush base, by a method wherein conductive power-distribution plates whose polarity is different from each other are attached to the surface and the rear of the brush base while connector parts are used as starting points. SOLUTION: In a structure, two power-distribution plates 13a, 13b are arranged respectively on both faces of a brush base 11 in such a way that their polarities are different. Thereby, a place in which the distance between the two power-distribution plates becomes narrow when both plates are overlapped concentrically is eliminated. As a result, a drop in the insulating property of a brush device due to the deposition of a brush powder is eliminated, and the insulation resistance of the brush device can be ensured sufficiently. In addition, the power-distribution plates 13a, 13b are used in a connection method. Accordingly, when the wiring layout of the respective power-distribution plates is set properly, pigtails 6 of respective power-distribution plates are made short. In addition, an intermediate terminal or the like is not required, thereby saving the space of the brush base 11.

IPC: H04L12/28
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To allow a control device having exchanged address with a device to be controlled before whose communication address is changed even when the communication address is changed due to duplication by adopting a configuration for the titled composite system where the control device compares substantial unique addresses of all devices to be controlled under the management of the control device every time the control device detects revision of the communication address of a device to be controlled so as to allow the control device to recognize a new communication address. SOLUTION: A transmission section 202 of a control device makes a communication request when detecting the possibility that other control device changes a communication address of a device to be controlled. Then a reception section 201 of the control unit acquires the communication addresses of all the devices to be controlled whose communication is available at present and the control unit acquires a unique address of each control device to be controlled by using the communication addresses. Then the control device refers to a correspondence table 205 between hosts and addresses to compare the unique addresses of each control device to be controlled and updates the correspondence table 205 between hosts and addresses after confirming that a communication address is changed.

Title: Electrostatic charging member for contact charger
Inventor: SEKIZAWA MASAKI
IPC: G03G15/02
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the surface contamination a photoreceptor by a electrostatic charging roller and the formation of abnormal images, such as white lines, even if electrostatic charge member is held standing over a long time in the state of stopping the image formation. SOLUTION: The electrostatic charging roller 2 of the contact charger is formed by mounting a conductive elastic layer 16 on a conductive arbor 15. The conductive elastic layer 16 is formed by using sulfur for a vulcanizing agent, vulcanizing the elastic layer and confining the content of the sulfur to <=1wt.%. As a result, the content of the sulfur which is the cause for the white line-like abnormal images by adhesion to the photoreceptor 1 side is confined to <=1wt.% and, therefore, even if the electrostatic charging roller 2 is held standing over a long time in the state of bringing the roller into pressurized contact with the photoreceptor 1, the contact part of the photoreceptor 1 and the electrostatic charging roller 2 is hardly contaminated with the sulfur. The occurrence of the white line-like abnormal images in the images formed on transfer paper is prevented.

IPC: B41J31/00
Filed: 1989-07-20
Abstract: PURPOSE:To accurately confirm the residual amount necessary for printing of a ribbon beforehand by changing the shape of the marker part of each color of the previous one cycle of a ribbon end from the shape of each color of proceeding one. CONSTITUTION:A leader part and an end part 2 are transparent and, to the space between them, an yellow part 4, a magenta part 5 and a cyan part 6 are serially formed as one cycle in this order in a strip shape so as to have a black marker at the head of each color and many cycles are arranged. The dimension of the black marker of each color is made constant at every part excepting the first cycle from the end part. The marker dimensions of respective colors of the first cycle from the end part are made different from other dimensions and also made different between colors and, further, a marker part is added behind the cyan part. By this method, when lap-printing is performed by simple color ribbon constitution, it can be judged whether lap-printing can be performed without changing a ribbon before printing and the change of a developed color when lap-printing stretching over two ribbons is performed can be prevented.
