Title: Method of driving plasma display panel
Inventor: MIMA KUNIHIRO
IPC: G09G3/294
Filed: 2002-07-29
Abstract: PROBLEM TO BE SOLVED: To display a high-quality video by adjusting the charge amount in a gas immediately before sustaining discharge, and also adjusting the intensity of writing discharge. SOLUTION: In a scanning line to be written last, the voltage to be applied across a sustaining electrode and a scanning electrode is arranged to be reduced (21 in Fig. 3). Thus, the wall charge amounts can be adjusted by reducing the charge amounts accumulated on the wall surface of a cell so as to offset a potential difference between the scanning side electrode and the sustaining side electrode after write discharge. Then, a video can be displayed in high quality by uniformalizing the wall charges of the cell at the time of finishing an address period.

Title: Stepping motor
Inventor: INOTA TAKASHI
IPC: H02K37/14
Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a stepping motor intended to reduce noise which is produced when the motor is driven and enhance the accuracy of rotational angle.  <P>SOLUTION: A cylindrical magnet 2 is fixed on a shaft 1 to form a rotor. A pair of bobbins 4A and 4B in phase A and phase B with coils 6A and 6B wound on them are placed on both sides of the rotor in the axial direction. Yokes 8A, 8B, 10A, and 10B which make pole teeth are fixed at both the ends of the bobbins, opposite to the circumferential surface of the magnet 2. With axial deflection produced in the position of the magnet 2, a difference is made between the clearance between the yokes in either phase and the magnet in the axial direction and the clearance between the yokes in the opposite phase and the magnet in the axial direction. Thus, magnetic attractive force in the axial direction is produced between the yokes and the magnet with the smaller clearance. A notch 11 in the circumferential direction is formed in the center portion of the magnet 2. Thus, the area of opposition between the magnet 2 and the pole teeth is kept constant against deflection of the rotor in the axial direction.  <P>COPYRIGHT: (C)2004,JPO

Title: Support body and pneumatic run-flat tire
Inventor: IZUMIMOTO TAKAHARU
IPC: B60C17/06
Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a support body and a pneumatic run-flat tire having excellent resistance to weight when a vehicle performs run-flat running while reducing weight of a leg part and facilitating work for rim assembly and rim release.  <P>SOLUTION: The leg part 28 is attached to a support part 26 and is assembled in a rim 12. Since high rigidity rubber 28A and low rigidity rubber 28B are laminated in the leg part 28, compression modulus of elasticity in the direction of vehicle weight support when the vehicle performs run-flat running is higher than a case where only low rigidity rubber is used. Consequently, deformation of the leg part 28 is suppressed to enable stable run-flat running. Moreover, bending modulus of elasticity is lower than a case where only high rigidity rubber is used due to a laminated structure of high rigidity rubber 28A and low rigidity rubber 28B to facilitate work by bending deformation when performing rim assembly and rim release. Furthermore, weight of the support body can be reduced when compared with a conventional support body.  <P>COPYRIGHT: (C)2004,JPO

Title: Adsl modem and its communication method
Inventor: NOMA NOBUHIKO
IPC: H04J11/00
Filed: 2002-08-02
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the interference of an upstream signal with a downstream signal due to the skirt phenomenon, thereby enabling the long distant ADSL communication.  <P>SOLUTION: A center side transmits downstream signals using a designated carrier predetermined by communication standards when a hand shake procedure starts. If no line can be connected with a party's ADSL modem in the signal transmission using the designated carrier, it transmits downstream signals again using an alternate carrier shifted to the high frequency side about the designated carrier adjacent to a carrier used for the upstream. A remote side detects signals with the designated carrier predetermined by communication standards from the downstream when a hand shake procedure starts. If the signal with the designated carrier cannot be normally received within a specified time after starting the shake hand procedure, it detects signals with the alternate carrier after the carrier change in coincidence with the carrier change at the transmit side.  <P>COPYRIGHT: (C)2004,JPO
