There is provided an oil separator for blowby gas exhibiting excellent oil separation performance in a stable manner. In a common flow path section of a gas flow passage in which the blowby gas flows and an oil passage provided with a bottom of the common flow path section where oil that has been separated from blowby gas by separation means provided midway along the gas flow passage, the width of a part of the common flow path section is regulated so as to become gradually smaller towards the bottom of the common flow path section, and a flow passage regulating section, for making part of the common flow path section that has the width regulated a restricted section, is provided so as to extend upwards from the bottom of the common flow path section.

An oil return passage that is open at its upper end to a cam chamber and is open at its lower end to a crank chamber is formed to extend from a cylinder head to a cylinder block. A heat exchanger having a double-pipe structure is housed in the oil return passage. Lubricating oil fed from the cam chamber is passed through an oil-collection outer passage of the heat exchanger, and separated oil fed from a separator case of a PCV system is passed through an oil-collection inner passage of the heat exchanger, so that heat of the lubricating oil is imparted to the separated oil. Thus, water contained in the separated oil is evaporated, and the amount of water flowing into an oil pan can be reduced.

A lens drive device in at least one lens barrel holding a lens moveably includes a motor to drive the lens; an acceleration detection section to detect an acceleration; and an output control section to control an output of the motor corresponding to the acceleration detected by the acceleration detection section. The output control section determines whether the acceleration detected by the acceleration detection section falls within a predetermined acceleration range or not. When the acceleration is determined to be within the range, a further determination of whether the lens drive device is in a stationary state is performed. When it is determined not being in the stationary state, the motor is driven by a maximum drive voltage. When it is determined being in the stationary state, a further determination of whether the posture is horizontal or not is performed.

A pedestrian protection apparatus for a vehicle, including a plate member which is disposed at a front face of the vehicle, which includes front and rear portions, and which is fixed at the rear portion to the vehicle with at least a leading end part of the front portion protruded from the front face of the vehicle, the apparatus being arranged to sweep a leg portion of a pedestrian, thereby protecting the leg portion, wherein the leading end part includes at least one horizontally extending portion and a plurality of vertically extending portions each having an anterior surface substantially orthogonal to a horizontal plane, the horizontally extending portion and the vertically extending portions being formed integrally with the leading end part so as to be alternately disposed in the frontward and backward direction of the vehicle and extend in a staircase-like form.

A web feed mechanism for stepwise or continuously feeding a web, such as a printing medium of a printer, or the like, from a roll of web. In the web feed mechanism, slackness, if any, can be absorbed by applying a drag force to the outermost winding of the web roll through a radially inwardly biased sliding member that slides tangentially of the web roll either in the forward direction, in which the web is to be let off from the web roll, or in the backward direction, in which the web is to be taken up onto the web roll. The sliding member is spring biased to slide backward. Upon the web being let off the web roll, the drag slides the sliding member forward, charges its spring and thereby keeps the web under tension. Upon discontinuance of web unwinding, slackness in the web is absorbed by the spring biasing the sliding member to drag the web roll to roll backward.

It is an object of the present invention to provide a shock absorbing structure for a vehicle that enables a simple and appropriate tuning of a load displacement characteristic, so that a desired amount of collision energy can be absorbed. In the present invention, each of two side walls which is integrally provided with top wall, to which a shock is applied, has a rectangular wave shape corrugated at a plurality of corrugated sections positioned to be opposed to each other in a direction perpendicular to a direction in which the shock is applied. In addition, outer flanges are integrally formed on an end section of each of the side walls, and a slit extending in the direction in which the shock is applied is formed on each of the corrugated sections.

A pedestrian protection apparatus disposed at a front of a vehicle for protecting a pedestrian in the event of a collision between the pedestrian and a front end of the vehicle, the apparatus including: a leg sweep member which is disposed at a lower part of the front end of the vehicle so as to protrude frontward for sweeping a leg portion of the pedestrian; and a fixing mechanism which fixes the leg sweep member to a structural member of the vehicle and which releases the fixation of the leg sweep member to the structural member when an object including the pedestrian advances, by an amount that exceeds a prescribed reference amount, with respect to the vehicle in a backward direction of the vehicle from a position of the front end of the vehicle against which the object has hit upon the collision.
摘要:
A method for controlling an iron ore pelletizing and pellet processing operation by evaluating the results of the on-stream analysis of the apparent specific gravity or apparent density distributions of the dry and fired pellet samples which permits the operator of the process to determine if any changes in the process control factors are required in order to impart into the fired pellets an apparent specific gravity or apparent density distribution optimized therefor as the fired pellets are used as a blast furnace charge composition. The method includes the use of an apparent specific gravity measuring step wherein a pellet process stream is periodically sampled and the pellet samples are presented in sequence to a weight measurement unit capable of producing an electric signal proportional to the weight of each sample, from which it proceeds into a volume measurement unit photoelectrically responsive thereto to produce an electric signal proportional to the volume of the sample. A computer is provided in response to the electric signals to compute the apparent specific gravity of each of the samples. This permits a rapid and accurate record of sample analysis to be maintained for the effective control of the process factors.
