摘要:
The present invention relates to crosslinked resin-coated silica fine particles each of which has a crosslinked resin coating formed of a structure of a single layer or a plurality of layers formed on the surface of each calcined silica fine particle through a vinyl-containing silane coupling agent, and the crosslinked resin-coated silica fine particles of the present invention have characteristic features in that the peeling of the resin coatings substantially do not occur when they are dispersed in a dispersing medium with ultrasonic vibration, and that they substantially do not move after the formation of a liquid crystal cell and substantially do not affect a liquid crystal itself and its orientation when used as a spacer for a liquid crystal display device.

An engine failure diagnosis system simply performs failure diagnosis of engine components, which are driven while an engine is operating, even at the time when the engine is stopped, and identifies a component that has failed and a location where a failure has occurred. The engine failure diagnosis system includes an ECM arranged to control an engine provided in an outboard motor of a watercraft. The ECM includes an actuation command section arranged to actuate engine components, which are driven while the engine is running, in a given manner, and a failure diagnosis section arranged to diagnose the presence of a failure in the engine components. The engine components of the engine are provided with actuated condition detecting sections arranged to detect a predetermined actuated condition. When the actuation command section outputs an actuation command while the engine is stopped, the engine components are actuated in a given manner.

It is an object of the present invention to provide an active energy ray curable resin composition exhibiting good adhesion to a polyolefin-based resin base material. More specifically, there is provided an active energy ray curable resin composition comprising: a block copolymer (C) that includes a polymer block (A) composed mainly of an olefin-based monomer unit and a polymer block (B) composed of a vinyl-based monomer unit having a carboxyl group, a carboxylic anhydride group, or a sulfonic acid group and/or a second vinyl-based monomer unit copolymerizable with the aforementioned vinyl-based monomer unit, the block copolymer (C) having a weight-average molecular weight from 5,000 to 100,000; and an active energy ray curable compound (D).
摘要:
An operating state determining device can determine whether or not an engine is in a certain operating state. A mode setting device can disable mode setting into a speed setting mode if a certain operating state of the engine has been determined, and can enable mode setting into the speed setting mode if the engine is not in the operating state.
摘要:
An engine has a lubrication system to lubricate at least a portion of the engine with lubricant. The lubrication system has a lubrication pump that periodically pressurizes the lubricant toward the portion of the engine. A first sensor senses an engine speed. A second sensor senses an engine load. A third sensor senses a temperature of the lubricant or the engine. A control device controls the lubrication pump. The control device determines a frequency of periodic pressurization by the lubrication pump based upon outputs from the first and second sensors. The control device determines a pressurization time of the lubrication pump based upon at least one of outputs from the first sensor, second sensor, third sensor, and a battery voltage.

The invention relates to an aqueous resin composition characterized by comprising 80 to 10 parts by weight of modified polyolefin with weight average molecular weight of 1000 to 100000, modified by copolymerizing polypropylene, polyethylene, copolymer of propylene or ethylene with .alpha.-olefin or degradation products of these under heat or with oxidizing agent, radical-generating agent or the like, with 0.1 to 20% by weight of one kind or not less than two kinds of acid anhydride, carboxylic acid or alcohol with radically polymerizable double bond, and 20 to 90 parts by weight of one kind or a mixture of two or more kinds of acrylic or methacrylic monomers, mixed or dissolved and polymerized in water in the presence of surfactant and polymerization initiator. And, the aqueous resin composition of the invention not only shows excellent adhesion to polyolefin, but also has adherence to other organic substrates and inorganic substrates. In addition, because of little organic solvent contained, it is excellent in the aspects of safety and hygiene and environmental pollution.
摘要:
A misfire detecting device is provided for a water jet propulsion watercraft in which a propulsion unit operates through an operation of an engine to propel the water jet propulsion watercraft. The misfire detecting device includes injectors arranged to inject fuel into the engine under a fuel injection amount adjusting control implemented by an electric control device, ignition plugs arranged to ignite the fuel injected into the engine from the injectors to operate the engine, an oxygen sensor arranged to detect that a misfire occurs in the engine, a warning lamp and buzzer arranged to inform that the misfire occurs, etc. The misfire detecting device prevents the warning lamp and the buzzer from informing the warning if the misfire is caused through the control by the electric control device. Accordingly, the misfire detecting device for a water jet propulsion watercraft ensures that an operator cannot mistake a misfire caused under a control for a misfire caused due to an abnormality of an engine or other components thereof.
