摘要:
A laminated material comprising an aluminum or polypropylene substrate and a resin composition layer coated on the substrate is described, wherein the composition layer comprises from 60 to 99.9% by weight of an ethylene-based copolymer and from 40 to 0.1% by weight of polypropylene modified with unsaturated carboxylic acid or its anhydride, and the composition layer is coated on the substrate by an extrusion lamination method. This laminated material has excellent physical and chemical properties, and is very useful as a wrapping material, particularly for use in automatic wrapping of foods, drinks, tools, and so forth.

A process for preparing oxymethylene polymers which comprises polymerizing trioxane or both trioxane and a specific cyclic ether in the presence of a catalytic amount of a boron fluoride-type catalyst, stopping the polymerization, and then subjecting the resulting polymer to a terminal stabilizing treatment, wherein the polymerization is stopped by adding a specific trivalent organic phosphorus compound and then the terminal stabilizing treatment is performed without removing the catalyst from the polymer.

A boat that allows effective steering even when the motor output power is decreased due to the low battery charge includes a first predictive determination unit arranged to compare an actual charge amount of a battery supplying an electric power to a steering motor or a predicted charge amount of the battery calculated from a predicted working current with a threshold predetermined in relation to running states; a steering load detector arranged to calculate a required output value of a steering motor necessary to steer an outboard motor while the boat is under way; and a steering load controller arranged to control the required output value to be decreased from the present output value when the first predictive determination unit determines that the threshold is larger than the battery charge amount.

A telephone exchange system includes a connection interface connecting a communication line and a plurality of extension telephones, a database having a dial-in conversion table registering a received number in association with a number after conversion for a dial-in incoming call, and an extension number table registering an extension telephone in association with an extension number of the extension telephone, and a main controller connected to the connection interface and the database. When the dial-in incoming call comes from the communication line, the main controller retrieves an extension number which coincides with the received number from the extension number table. When there is an extension number which coincides with the received number, the main controller causes an extension telephone corresponding to the extension number to ring.

A boat propelling system capable of reducing electric power consumption includes an outboard engine main body, a swivel bracket arranged to allow the outboard engine main body to pivot in a right-left direction with respect to a hull, an electric motor arranged in the swivel bracket to pivot the outboard engine main body in the right-left direction, a transmission mechanism arranged in the swivel bracket to transmit a driving force of the electric motor to the outboard engine main body, a locking clutch arranged to lock the transmission mechanism so that the outboard engine main body will not be pivoted in the right-left direction by an external force acting on the outboard engine main body, a steering section arranged to steer the outboard engine main body, a steering angle sensor arranged to detect a steering angle of the steering section, a pivot sensor arranged to detect an actual pivot angle of the outboard engine main body, and an ECU arranged and programmed to control the electric motor based on a result of a comparison between a threshold value and an angle difference between a target pivot angle of the outboard engine main body based on the steering angle and an actual pivot angle. The threshold value can be set based on a boat speed and a trim angle.

摘要:
A steering wheel, operable by an operator, can be electrically connected to an electric motor to provide an actuation signal corresponding to the amount of a steering wheel operation to the electric motor, a reaction motor for applying a reaction to the steering wheel, and an ECU for controlling the electric motor are provided. The ECU can include at least one of an operation status detection device for detecting an operation status corresponding to the steering wheel operation, a running status detection device for detecting a running status of the watercraft, an outboard motor status recognition device for recognizing a status of the outboard motor, such as the installation number thereof, and an electric motor status detection device for detecting a status of the electric motor. The ECU can also include a torque computation device for making a torque target value larger depending on the detection value from the at least one device, and a reaction motor control device for controlling the reaction motor in accordance with the torque target value computed by the torque computation device.

A watercraft includes a plurality of outboard motors. Each of the outboard motors has a generator and a rudder deflecting system driven by an electric motor. The outboard motors are turned by the rudder deflecting systems thereby steering the watercraft. Electric power can be supplied from the generators of others of the plurality of outboard motors to the rudder deflecting system of an arbitrary outboard motor among the plurality of the outboard motors. Using this arrangement it is possible to provide a watercraft in which electric power for operation is stably supplied to the rudder deflecting system without increasing the size of the generators.

摘要:
A swivel bracket of an outboard motor pivots about an axis of a tilt shaft disposed at a front end of the bracket unit and extending horizontally in a vertical plane to adjust a tilt angle and a trim angle of the outboard motor. A steering system for the outboard motor includes a pivotal gear attached to the swivel shaft, a drive mechanism driving the pivotal gear, and an electric motor providing drive force to the drive mechanism. Preferably these steering system components are positioned between the swivel bracket and an engine cowling of the outboard motor.
