Abstract: A delivery server includes a processor including hardware, the processor being configured to: transmit arrival information of a product to a user terminal carried by a user who has ordered the product; transmit, in a case where unattended delivery is instructed by the user terminal, unattended delivery information to a home delivery terminal of a delivery person who delivers the product, and request a signature of the user; transmit the signature information to the home delivery terminal in response to receiving signature information regarding the signature of the user from the user terminal; and transmit delivery completion information of the product to the user terminal.

Abstract: An improved DC electrical starting motor and method for starting internal combustion engines that reduces starter motor noise in the period after the engine starts by effecting breaking of the starter motor shaft at that time. Preferably the braking is accomplished by regenerative braking.

Abstract: An improved DC electrical starting motor and method for starting internal combustion engines that reduces starter motor noise in the period after the engine starts by damping the vibrations caused by motor cogging as it coasts to a halt, is done by reducing cogging torque and or rigidifying the starter motor housing. In addition several new structures foe reducing cogging torque are disclosed.

Abstract: A DC motor which is small in size and capable of effecting a higher output, and in which magnet size is determined through a parameter by which the peak output characteristic corresponding to the shape and size of the yoke can be recognized properly.

Abstract: A novel method for crosslinking a polyolefin comprising reacting a polyolefin, which is a low density polyethylene having a density less than 0.93 and melt index of 0.1-0.5 g/10 min. or a polyolefin mixture containing a low density polyethylene having a density less than 0.93 as major component, with an organic silane and a free radical generating compound to form a silane-grafted polyolefin, then mixing silane-grafted polyolefin with a silanol condensation catalyst, and heating them. According to this method, the crosslinking takes place concurrently with forming by extrusion, and a shaped article having a high degree of crosslinking with smooth surface is obtained. The method according to this invention is especially suited for covering electrical wires with polyolefin.
