An air-cleaner support structure includes an air-cleaner, a first support portion and a second support portion. The air-cleaner is supported in an engine room via the first support portion and the second support portion. The first support portion is connected to the air cleaner using a bolt and the second support portion is connected to the air-cleaner using an insert member. The distance from the engine to the first support portion is shorter than the distance from the engine to the second support portion.

An image forming apparatus which is capable of adjusting the color density while improving the printing efficiency. A color density adjustment value-adjusting unit adjusts a color density adjustment value in predetermined adjustment timing so as to keep colors of an image constant. A color density adjustment value-storing unit stores the color density adjustment value in advance. An adjustment timing occurrence-determining unit determines whether or not the adjustment timing occurs during execution of an image forming job. A color density adjustment value-predicting unit predicts the color density adjustment value in the adjustment timing determined to occur, based on the color density adjustment value stored in advance. The color density adjustment value-adjusting unit is adapted to adjust the color density adjustment value based on the predicted color density adjustment value.

A four-stroke-cycle engine of a vehicle such as snowmobile comprises a crank case, which is dividable into a plurality of crank case components having mating surfaces, through which the crank case is assembled, a crank shaft rotatably supported in the crank case at a portion between the mating surfaces of the crank case components, and a belt driven-type continuously variable transmission mechanism operatively connected to one end of the crank shaft through a clutch belt. The continuously variable transmission mechanism includes a drive shaft, and the clutch belt is stretched around the drive shaft and the crank shaft so that a tensioning direction of the clutch belt is shifted from a line passing the mating surfaces of the crank case components at a predetermined angle therebetween.

An air pressure information display device of a vehicle tire has a normal air pressure storage module (10a) for storing a normal air pressure of a tire corresponding to a tire temperature, an excessive/deficient amount detection module (10b) for detecting the excessive/deficient amount from the normal air pressure on the basis of the stored normal air pressure, and air pressure information detected by an air pressure information detection module (6-9), and a display control module (10c) for controlling a display (11) to display the detected excessive/deficient amount. Hence, since the user is informed of the excessive/deficient amount from the normal air pressure, he or she can appropriately determine an air pressure state of a tire even when he or she does not recognize the normal air pressure.

This invention provides a catalyst for partial oxidation of unsaturated hydrocarbon, characterized in that the catalyst comprises finely divided gold particles immobilized on a titanium-containing oxide and is one subjected to a silylating treatment or a hydrophobilizing treatment. The catalyst of the invention shows little deactivation with time in a reaction for preparing an epoxide from unsaturated hydrocarbon, and can stably retain a high selectivity, a high activity and like excellent catalytic capability for a long term.

An image processor includes a first reader which obtains a first signal corresponding to visible information read on an original, and a second reader which obtains a second signal corresponding to invisible information on the original. A comparator compares the first and second signals to discriminate a predetermined pattern on the original.
摘要:
A partially-oxidizing catalyst for hydrocarbon contains gold, titanium oxide and a carrier whose specific surface area is not less than 50 m.sup.2 /g. The carrier is preferably made from silicon oxide and/or aluminum oxide. The content of gold in the catalyst is preferably set in the range of 0.005 to 5% by weight. Further, another partially-oxidizing catalyst for a hydrocarbon contains gold, a titanium-containing metal oxide, and at least one element selected from the group consisting of an alkaline metal, an alkaline-earth metal and thallium. With these compositions, it becomes possible to provide a partially-oxidizing catalyst for a hydrocarbon having superior activity and selectivity in partially oxidizing the hydrocarbon in the presence of hydrogen and oxygen. Moreover, a partially-oxidizing method for a hydrocarbon is used for partially oxidizing the hydrocarbon by using any of the above-mentioned partially-oxidizing catalysts in the presence of hydrogen and oxygen. This method makes it possible to manufacture an epoxide from a hydrocarbon of the olefin family and also to manufacture an alcohol and/or a ketone from a saturated hydrocarbon, with high selectivity and high conversion.
摘要:
A brake system for a vehicle includes a liquid pressure generating device for generating a liquid pressure for braking dependent upon a manual operation, an actuator for generating a liquid pressure for braking dependent upon an electrical command signal, and an electromagnetic switchover valve which is switchable between a first state in which a wheel brake is connected to the liquid pressure generating device upon deenergization of the electromagnetic switchover valve, and a second state in which the wheel brake is connected to the actuator upon energization of the electromagnetic switchover valve. The brake system further includes a controller. The controller determines whether the regulation of braking force is necessary depending upon the behavior of the vehicle or a wheel, determines an amount of braking force required to be generated by the brake, and determines an electrical command signal to be applied to the actuator, dependant upon the required amount of braking force, when the regulation of brake force is necessary. Further, the controller controls the switching operation of the electromagnetic switchover valve device between the first state in which the regulation of braking force is unnecessary, and the second state in which the regulation of braking force is necessary. The switching of states may be based upon an elapsed time or based upon equalizing pressures between the actuators and the liquid pressure generating device. Thus, it is possible to reduce the frequency of operation of each of the actuator and the electromagnetic switchover valve device and to eliminate the need for a stroke accumulator, thereby providing a simplified structure.
