Title: Apparatus and method for detecting abnormality of tool
Inventor: HAGA DAISUKE
IPC: B23Q17/09
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To judge whether or not abnormality, such as tool breakage, has occurred, without being affected by a machining load. SOLUTION: Tool inertia J1 during an acceleration period of a spindle motor 7 at S110 and tool inertia J2 during a deceleration period of the spindle motor 7 at S140 are estimated respectively. When J2 is smaller than J1, it is judged that the tool breakage has occurred. And then, the process is ended after carrying-out processing for abnormal situations (S180). By such processing, a machining load does not affect accuracy of the estimation because tool breakage is judged when machining is not carried out. Further, time for the judgment is not necessary because the judgment is carried out without specially requiring the time for the judgment.

Title: Insertion decision controlling method for opening/ closing body
Inventor: FUEKI MASAHIRO
IPC: B60J7/057
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an insertion decision controlling method for an opening/ closing body capable of quickly making an insertion decision with high degree of accuracy. SOLUTION: An angular acceleration of a motor is calculated, and the insertion decision is made when such a state that the angular acceleration is not higher than threshold value elapses for a predetermined time or more. While there is possibility of making a wrong decision on the lowering of a closing operation velocity resulting from the increase of friction by the insertion through the decision made by a period or a rotational velocity (angular acceleration), the accurate insertion decision can be obtained without being influenced by secular deterioration from seeing a state of deceleration (variations in the angular acceleration) without being influenced by high and low of the rotational velocity (angular acceleration) of the motor.

Title: Deflection scanning device
Inventor: MIKAMI KEIICHI
IPC: G02B26/10
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To suppress a deflection scanning device from being vibrated more than needed by dispersion generated in the case of assembling a light deflector to an optical box. SOLUTION: A substrate 14 is fixed to the optical box so as to allow the outer peripheral wall of the shaft body 16 of a driving motor to abut on a holding hole 22 (the side of the centroid O1 of the substrate 14). By that, since the shaft body 16 and the holding hole 22 are abutted on the optical box at a position close to the centroid O1 of the substrate 14, the substrate 14 is surely fixed at the position of high rigidity of the optical box. Thus, even when a polygon mirror is rotated at high speed, the rigidity of the substrate 14 is high and the deflection scanning device is not vibrated. Thus, a laser beam source, a lens and a mirror, etc., housed in the optical box are not vibrated either and the image quality of print images is improved.

Title: Echo control system
Inventor: MATSUO NAOJI
IPC: H04B3/23
Filed: 2001-04-05
Abstract: PROBLEM TO BE SOLVED: To provide an echo suppressing process suitable even for a state in which a fluctuation of a delay amount in network transmission is large, independent of a callee-side system. SOLUTION: A voice input from a speaker 10 via a microphone 11 is delivered to a terminal equipment 14 of a callee side via a VoIP application 13 and an internet 30. A speaker's voice is input to an echo canceller 100 in parallel. The canceller 100 detects acoustic characteristic information previously or via a dynamic echo route, regulates a filter coefficient for generating an echo suppressing signal, and receives a tuning from a user. The canceller 100 processes the delivered acoustic characteristic information from speaker's voice signal based on the tuning amount and generates the echo suppressing signal. The echo suppressing signal is subtracted from a response signal including the echo re-input from the speaker 22 of the callee side via a microphone 21.

Title: Method and system for reporting information permitting crossing of railroad intersection
Inventor: IZUMI HIROYUKI
IPC: G08G1/00
Filed: 2001-04-16
Abstract: PROBLEM TO BE SOLVED: To effectively use a road space beyond a railroad crossing to prevent a traffic snarl at the railroad crossing while securing the safety of a vehicle crossing the railroad intersection. SOLUTION: The overall length of a vehicle 501 which will cross the railroad intersection is measured on a road 801 before the railroad intersection by a vehicle overall length detector 102. The overall length of the space where no vehicles exist on a road 803 beyond the railroad intersection is measured by a road space overall length detector 103.

Title: Vehicle motion control device
Inventor: MATSUURA MUNENORI
IPC: B60W10/14
Filed: 2001-04-20
Abstract: PROBLEM TO BE SOLVED: To carry out an avoidance travel for an obstacle by appropriately actuating a vehicle behavior control device over the whole of the avoidance travel and to inhibit an intervention of an unrequired control as less as possible even if an error exists in the information of the obstacle. SOLUTION: An obstacle to the own vehicle 1 is recognized in advance and the avoidance travel control part 80 considers the relative motion of the own vehicle 1 and the obstacle and accurately determines whether or not the own vehicle 1 can avoid the obstacle only by a braking operation. In the case where the obstacle cannot be avoided only by the braking operation of the own vehicle 1, the vehicle behavior control parts 60, 65, 70 and 75 are transferred to an avoidance travel mode corresponding to an operation of a steering wheel and a vehicle behavior. The vehicle behavior control parts 60, 65, 70 and 75 perform required control corresponding to the variation of the operation of steering wheel and the vehicle behavior during the avoidance travel mode.  The lateral motion of the own vehicle 1 is monitored during the avoidance travel mode and when the own vehicle 1 arrives at the obstacle, the avoidance travel mode is released in the case where the own vehicle 1 does not carry out motion for avoiding the obstacle.
