A power assist wheelchair includes a wheel, an electric motor that drives the wheel, an encoder that detects rotation of the electric motor, and a control device that controls the electric motor. The control device includes a total torque value calculator that calculates a total torque value based upon only a detection signal of the encoder, an assist torque value calculator that calculates an assist torque value based upon an output current of the electric motor, a manual torque value calculator that calculates a manual torque value based upon a difference obtained by subtracting the assist torque value from the total torque value, and a target current determiner that determines a target current of the electric motor based upon the manual torque value.

In the tape winding apparatus of the present invention, the recessed blowout part is formed at the tip end part of the nozzle and a plurality of slits are disposed at the blowout part. Therefore, the range where the sprayed gas presses the tape becomes wide, and the entire force which presses the tape becomes strong. Thereby, a constant biasing force can be applied to the outer peripheral surface of the tape roll, as a result of which, the tape roll of favorable quality can be obtained.

A packaging apparatus packages a cylindrical article having a hollow region therein by gathering an end of a wide packaging sheet wrapped around the cylindrical article, and pressing the gathered end into the hollow region in the cylindrical article. The gathered end of the packaging sheet is pressed into the hollow region in the cylindrical article by a presser which has an outside diameter smaller than the diameter of the hollow region and an inside diameter greater than the outside diameter of a core tube used to gather the end of the packaging sheet. The core tube is withdrawn from the hollow region before the gathered end of the packaging sheet is fully pressed into the hollow region by the presser. The packaging apparatus can reliably gather and squeeze a packaging sheet having long opposite ends. Since the gathered end is pressed into the hollow region in the cylindrical article, the hollow region can be sealed against entry of humidity, air, and light without use of special members such as labels or plastic caps.

Method of and apparatus for packaging cylindrical article

A method of and apparatus for checking a wrapping state of a wrapped roll having end face covers by detecting the force required to press-fit a bushing into a cylindrical core tube and comparing the detected force with a threshold value which is based on the correlation between the force required to press-fit the bushing into the cylindrical core tube and the state of tucking of the end face covers.

Method and apparatus for checking the wrapping state of a roll

An original roll positioning device sets a position of an end face of a new roll at a predetermined reference position. An end pull-out device sucks and pulls out the leading end of the new web from the positioned new roll at a predetermined length. A pair of roll-up chucks of an end roll-up device holds both sides of the leading end of the pulled-out web, and the roll-up chucks are rotated to roll up the leading end of the web at a predetermined length. A suction box sucks the web at a part between the roll up chucks and the roll, and then a cutter cuts the web along the width of the web to form a splicing part. The splicing part is sucked by the suction box, and the spliced part is made to wait in this state until the start of the splicing operation.

Web splicing preparation method and apparatus

A wrapping state of a wrapped roll of a continuous sheet material which is rolled and wrapped with a sheet-like wrapping material is checked by taking an image of the wrapped roll placed in a predetermined position, and processing information on the image of the wrapped roll with respect to the density of the image, thereby detecting data on wrapping state of the wrapped roll, and determining whether the wrapping state of the wrapped roll is satisfactory on the basis of the detected data.

A package of rolled photosensitive mateiral comprising a core, a photosensitive strip material wound around the core, a light-shielding leader connected to the end of the photosensitive strip material to shield the peripheral surface of the photosensitive strip material from light and side light-shielding covers connected to both sides of the light-shielding leader so that the boundary between the side light-shielding covers and the light-shielding leader corresponds to the boundary between the peripheral surface and the side surface of the photosensitive strip material. The core is formed by laminating at least 2 sheets of a base paper being moistureproof. The side light-shielding covers are composed of a composite film having a polyethylene film having light-shielding ability and a uniaxially oriented film or a biaxially oriented film made of polyester, polyethylene polypropylene or nylon with the length of the side light-shielding covers being not less than twice as long as the outer periphery of a roll of the photosensitive strip material.

Package of rolled photosensitive material

A packaging apparatus for packaging rolled articles. The apparatus forms a pair of packaging materials for wrapping side portions of the rolled article. Edges of the pair of packaging materials are adhered to additional packaging material which wraps a circumferential portion of the rolled article. A splicer splices a trailing end of the second packaging material to a leading end of the rolled article and a winder winds the leading end of the rolled article and the second packaging material around the periphery of the rolled article. A gusseting device gussets the pair of packaging materials along the sides of the rolled article.

Packaging apparatus

Packages of a rolled photosensitive material comprise a core and a photosensitive material wound around the core, and one package further comprises a light-shielding leader connected with an end of the photosensitive material to shield the circumferential surface of the photosensitive material from light and a pair of light-shielding covers adhered to both sides of the leader in a peelable state to shield the side surfaces of the photosensitive material. Another package further comprises a light-shielding leader connected with an end of the strip material to shield the circumferential surface of the photosensitive material from light and a pair of side light-shielding covers adhered to shield both sides of the rolled photosensitive material so that the joining end substantially conforms to a boundary between the circumferential surface and the side surface of the photosensitive material, wherein at least one of the light-shielding leader and the side light-shielding cover is made of a tearable material in the boundary direction.
