Title: Method and device for transmitting and receiving packet
Inventor: ZAITSU MAKOTO
IPC: H04L12/801
Filed: 2003-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To obtain maximum throughput without consuming the traffic of a transmission path while suppressing the complication of the configuration of a receiving side device and a load increase in a processing operation.  <P>SOLUTION: A packet transmitting side device preliminarily acquires a packet transmission interval when a packet can surely be received from a packet receiving side device, stores the packet transmission interval in a transmission interval storing part and uses the interval to perform packet transmission by a transmission control part. This can prevent the occurrence of packet retransmission due to the unreceivable state of the packet receiving side device. In addition, if the receiving capability of the packet receiving side device drops in its actual operating state for some reason or other, the packet transmitting side device measures the receiving capability of the packet receiving side device and updates contents of the transmission interval storing part by using an optimum transmission interval. This always enables stable packet transmission and reception.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Liquid jet method, liquid jet system, and liquid jet execution program
Inventor: YOSHIDA ATSUSHI
IPC: B41J2/175
Filed: 2003-02-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid jet method whereby a total liquid jet time can be more shortened by reducing a load although whether or not a liquid shortage takes place is judged, a liquid jet system and a liquid jet execution program.  <P>SOLUTION: Only when a remaining amount S of each ink in each ink cartridge becomes not larger than a monitoring judgment amount R (YES in a step S15), it is judged whether or not the remaining amount S of the ink which becomes not larger than the monitoring judgment amount R is not smaller than a use amount T necessary for printing, that is, whether or not printing is possible without causing the ink shortage in the middle of the printing (step S30). In other words, when it can be judged that the remaining amount S of the ink is not smaller than the monitoring judgment amount R and the ink shortage is apparently not brought about during the printing, the use amount T for the ink is not calculated. Since calculating the use amount T applies a large load to a computer CPU, the load of the CPU is reduced and a printing time from a printing execution to a printing end can be shortened.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a controlling device for a three-phase AC motor that corrects delay time when ON delay time is different from OFF delay time in switching elements, and that has improved control stability.  <P>SOLUTION: In the controlling device for a three-phase AC motor that controls an inverter using power switching elements, means are provided that calculate a delay time correction value and a voltage command correction value based on the ON delay time and the OFF delay time of the power switching elements, that transforms DC-AC coordinate using a corrected phase angle based on the delay time correction value, and that corrects pulse width of PWM control using the voltage command correction value. When the ON delay time is represented as Ton, the OFF delay time as Toff, and dead time as Tdead, a sum of time from reference angle reading up to a command phase angle (3/2)ΔT and the delay times (Tdead+Ton+Toff)/2 is multiplied by electrical angular speed ωre. A value calculated by adding the product to a reference phase angle θre is used as a command phase angle θre* after correction.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
