Title: Hand for robot
Inventor: SHIRAKAWA TAKESHI
IPC: B25J15/04
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a hand for a robot to simplify structure and facilitate processing and manufacture, cause movement to smooth and reliably hold a work, cause jolting to hardly occur, and further and sense holding of a work. SOLUTION: This hand for a robot comprises a base body 3 in which a containing space 2 having an opening part 1 is formed; a moving body 4 to be slidably contained in a containing space 2; a plate 5 to close the opening part 1 of the containing space 2 in which the moving body 4 is contained; and holding claws 6 situated in two or more spots situated closer to an outer periphery than the central part of the upper surface of the plate 5. When air is fed in the containing space 2, the moving body 4 is slid and the central part of the plate 5 is pushed out to the outside to curve the plate 5 in a manner to incline downward to the outer peripheral side from a central part.  When air in the containing space 2 is exhausted, the moving body is slid in a reverse direction to a direction during a feed of air and the central part of the plate 5 is released from press and the plate is returned to a state before curving. When the plate 5 is curved in a manner described above, the holding claw 6 is inclined outward to hold or release the work 7 and when the plate 5 is restored, the holding claw is returned to the inside to release or hold the work 7.

Title: Paper towel distributing machine
Inventor: YAMAMOTO HIROSHI
IPC: B65H16/10
Filed: 1988-03-28
Abstract: PURPOSE:To linearly guide a paper towel and to prevent the generation of meandoring by arranging a drawing roller and a feeding roller in facing them forward and backward, stringing a belt between the circumferential surfaces of both rollers, and simultaneously, causing the widths of both rollers to be remarkably smaller than the width of the paper towel. CONSTITUTION:In the upper edge parts of right and left side plates 21 and 21, shafts 45 and 46 are rotatably shaft-supported, respectively. In the central parts of the shafts 45 and 46, a feeding roller 47 and a drawing roller 48 of the same diameter are fixed in being faced, opposingly and a belt 49 of the same width as the widths of the rollers 47 and 48 are strung between the outer circumferences of the rollers 47 and 48. The widths of the rollers 47 and 48 are made remarkably narrower than the width of a paper towel P and, simultaneously, located in the central part in the width direction of the paper towel P. For such reason, friction force is applied only to the central part of the paper towel, and the paper towel is drawn out. Consequently, since the paper towel is drawn out while the force is centralized only at one pint, the paper towel P can be fed without meandoring.

Title: Method for starting ac motor
Inventor: KATOU KIYOHARU
IPC: H02P1/46
Filed: 1979-06-14
Abstract: PURPOSE:To reduce the capacity of a starting motor and to suppress the effects of torsional vibration on a driving system by switching the starting operation with the starting motor to the full-voltage starting operation at the point where the torsional vibration value of the driving system is attenuated to the value which does not affect the driving system after the starting. CONSTITUTION:After the torsional vibration stress of a synchronous motor driving system has reached the maximum value, and until the speed of the drive system reaches a speed nl at which the drive system is not damaged, the synchronous motor 1 is started by a hydraulic starting motor 3. When a speed sensor 51 has sensed that the voltage induced in a field coil has reached the value corresponding to the speed nl, a breaker 6 is actuated and the switching to the full-voltage starting is made. In this way, the capacity of the hydraulic starting motor 3 can be reduced.

Abstract: PURPOSE:To effectively protect a catalyst from being overheated by stopping feedback control and setting a fuel injection time longer than the minimum injection time in the case where an output signal of an oxygen concentration detector is continued at a set voltage or less for a preset time when decelerating operation is performed. CONSTITUTION:An electronic control unit 30 determines during operation of an engine, if output voltage V of an oxygen concentration detector 20 is set voltage V1 or less, in the case when it is detected that the state of engine operation is transferred in a decelerating operation condition. And an counter is operated in the case when output voltage V is less than set voltage V1 a lean flag is set (i) after a preset time passes, feedback correction factor is set at 1 and feed back control is stopped. Accordingly, fuel injection time longer than a predetermined minimum injection time, an air-fuel mizture is made richer, and unburnt gas is prevented from being exhausted while preventing a catalyst from being overheated. Accordingly, the flag is reset in the case where output voltage V is higher than set voltage V1.

Title: Driving device
Inventor: KIMURA HIDEYUKI
IPC: H02N10/00
Filed: 1985-04-10
Abstract: PURPOSE:To enable compacting of a driving, by a method wherein, by the use of a member made of a shape memory alloy having a high restoration force, a restoration force is converted into a deformation amount by a lever theory to drive an object. CONSTITUTION:A single wire 2a having a wide sectional area is used as a member made a shape memory alloy having a high restoration force. Tensile coil springs 2 produce a bias force, and are attached to both ends of a lever 4 rotating around a fulcrum 3. A driven object 5a is connected to the one end of the lever 4 through a transmission wire 6. A wirelike shape memory alloy 1a is energized by a power source 9 for heating, and when the alloy is heated to a transformation temperature, it is about to shrink to produce a high restoration force (f). The restoration force (f) is converted into a high deformation amount L by the lever 4, resulting the possibility to widely move the driven object 5a to a driven object 5b. This enables compacting of a driving device.

IPC: H03M1/10
Filed: 1982-05-04
Abstract: PURPOSE:To obtain a digital data with high accuracy where both of the drift and the offset are corrected, by correcting an error due to the offset of an AD converter. CONSTITUTION:A control section 9 performs the operation subtracting only the drift from an AD converting data of an analog input signal 1, by setting on or off a control switch 22. Then, the input signal is taken to 0V accurately and the control section 9 subtracts the drift from the AD-converted data and gives the result to a data bus 12. The data given to the data bus 12 is a data representing the offset value. The data of the offset value is set to an offset correcting switch 18. The control switch 22 is changed over so as to form the logic by which the control section 9 corrects both of the drift and offset. Thus, the digital data with high accuracy correcting both of the drift and the offset is obtained.
