IPC: B65H49/10
Filed: 1995-04-03
Abstract: PURPOSE: To restrain tensile strength on a wire and smoothly deliver the wire by providing an elastic guide bar with at least the lower end elastically expand ed to the outer edge of a setting along the guide bar so that a column can be deflected when the delivered wire is tensed. CONSTITUTION: At the time when a wire rod E which has been delivered from a wire bundle WE begins to be delivered from another wire bundle WE, the end 31 of a lead-out member 30 is still located above a supporting tool 20 having supported the wire bundle WE. On this account, the wire E is slantly delivered. Tensile strength on the wire E works to tense a column 40 and an elastic guide bar 24 for the supporting tool 20 to the lateral direction. The column 40 which has a coil spring 43 in part can elastically be deflected to the lateral direction. Still, the column 40 can also be extended to the longitudinal direction. In this way, tensile strength on the wire E can be relaxed and the hitch of the wire E can be removed.

Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To control the liquid leakage at the usual brake time, in a hydraulic brake system including a hydraulic brake in which the brake is exerted by a hydraulic pressure. SOLUTION: When a liquid leakage is detected (S11), a liquid leakage is controlled and restrained at the usual operation time (S14), when an operation liquid stays in a reservoir (S13). As the brake hydraulic pressure is made lower than the required hydraulic pressure intended by a driver and the hydraulic pressure applied to a liquid leak place is lowered and the liquid leakage is restrained. The hydraulic fluid in the reservoir can be kept for a long time. When the brake is in the usual operation state and the liquid leakage is detected, the liquid leakage is controlled and restrained.

Title: Motor driving device
Inventor: YAMAMOTO KAZUYUKI
IPC: H02P7/29
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce the power from a solar battery and a battery, and, at the same time, to quickly charge the battery by controlling the number of revolutions per unit time of a motor which is driven with the electric power form the solar battery and/or battery to a prescribed value. SOLUTION: A PWM(pulse width modulation circuit) 16 always detects the number of revolutions per unit time of a motor 15 and, at the same time, controls the number of revolutions of the motor 15 to a prescribed value or its vicinity by chopping the direct current supplied to the motor 15 from a solar battery 12 or a battery 14 in a pulse and controlling the on-duty ratio of the pulse width of the pulse so that the detected number of revolutions (rotating speed) of the motor 15 may become a fixed value (speed). Therefore, the power consumption of the motor 15 is also nearly fixed to a prescribed value. Therefore, when the electric power generated from the solar battery 12 exceeds the nearly fixed power consumption of the motor 15, the excessive electric power is not used for increasing the number of revolutions of the motor 15, and so forth, but for charging the battery 14.  Therefore, the charging time of the battery 14 can be shortened.

When the input signal is at a high level, a current i2 flows from the dividing point B to the dividing point A, a current 1i flowing to a collector of the differential TRQ1 is decreased by the share and a current i3 flowing to an output TRQ3 is increased. Then an ineffective current flowing to the collector of the Q1 is reduced and the operating current flowing to the Q3 is increased, thereby increasing the drive capability and realizing high speed operation.
