Abstract: <P>PROBLEM TO BE SOLVED: To provide a network print system by which response when a portable terminal is lost is facilitated.  <P>SOLUTION: A registration processing part 32 of a lost equipment management server 30 registers an equipment ID of the lost equipment in an equipment loss list upon receiving notification from an owner who notices the loss of the portable terminal 40. When the portable terminal 40 receives an e-mail including a document ID, a print request including the document ID and the equipment ID, is transmitted to a complex machine 20 by infrared communication. When a print control part 24 of the complex machine 20 transmits the equipment ID to the lost equipment management server 30, a judgment processing part 34 judges whether the transmitted equipment ID is registered in the equipment loss list, and returns its judgement results. The print control part 24 refuses the print request when the portable terminal 40 is judged to be the lost equipment by the judgment results.  <P>COPYRIGHT: (C)2007,JPO&INPIT

IPC: B60C23/04
Filed: 2005-09-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for filtering a signal transmitted to the central unit of a monitoring system that is equipped on a vehicle.  <P>SOLUTION: Pressure in a tire is measured at a period θ, and if there is a change ΔP in the pressure between pressure values measured sequentially, that change is derived. In parallel, temperature in the tire is measured at the same period θ; and when the change ΔP in pressure between two pressure values measured sequentially is larger than the absolute value of a predetermined threshold voltage Sp, the temperature difference ΔT between the two temperature values measured at the same moment as the measured pressure values is calculated. A correction factor Cp, that becomes Cp=ΔP/ΔT, is derived from the temperature difference. When ΔT=0 or the correction factor Cp is positive and is larger than a predetermined threshold coefficient Cp1, or the correction factor Cp is negative and is not between the minimum and the maximum threshold, instructions are given to the central unit so as to transmit a signal that expresses changes in the pressure.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

IPC: G03G15/01
Filed: 2005-09-21
Abstract: <P>PROBLEM TO BE SOLVED: To stabilize discharge of developer from a discharge port without increasing the scale of a developing device.  <P>SOLUTION: Developer is conveyed by a second stir conveyance auger 40. Excessive developer overflows from the discharge port 64 into a storage chamber 62. The shaft 42 of the second stir conveyance auger 40 is provided with a discharge promoting blade 48 of a plate shape in its axial direction. Both ends of the discharge promoting blade 48 are joined to spiral parts 44 and counter spiral parts 46. Before developer is conveyed to a diaphragm part N by the corresponding spiral part 44, the developer is conveyed in the direction of arrow S by the discharge promoting blade 48, so that the flow of developer is dispersed. This prevents the developer from rising in the diaphragm N. Consequently, a shutter 60 is not closed by the rise of developer and thus the developer is stably smoothly discharged from a discharging port 64. In addition, this eliminates the need to increase the height of the discharging opening 64 or opening/closing stroke of the shutter 60, and avoids an increase in the scale of the developing device.  <P>COPYRIGHT: (C)2007,JPO&INPIT
