48results about How to "Reduce load fluctuation" patented technology

A blade-pitch-angle control device includes a memory unit in which predetermined parameters that affect the load fluctuation of blades, azimuth angles, and pitch-angle command values are stored in association with each other; an azimuth-angle detecting unit that detects the azimuth angle of each of the blades; a parameter-detecting unit that detects the predetermined parameters; a command-value receiving unit that receives pitch-angle command values for each of the blades from the memory unit, the pitch-angle command values being selected on the basis of the azimuth angle of each blade detected by the azimuth-angle detecting unit and the predetermined parameters detected by the parameter-detecting unit; and a pitch-angle-control command-value generating unit that generates pitch-angle-control command values for individually controlling the pitch-angle of each blade on the basis of the pitch-angle command values and a common-pitch-angle command value.

It is one object of this invention to provide a technique that is effective in diminishing the range of fluctuation of a load applied to a drive source when a seat main body in a vehicle seat moving apparatus is moved between a raised position and a lowered position.For this purpose, this invention provides a vehicle seat moving apparatus constructed as follows. Provided on a rotation base 31, for rotating a seat main body 10 between a position where it faces the front side of the vehicle and a position where it faces a door opening, is a widthwise slide base 41 that moves horizontally in the vehicle width direction while the seat main body 10 faces the door opening. The seat main body 10 is supported by the slide base 41 via four-bar linkage mechanisms 44. Guide rollers 46 are attached to upper link arms 44a of the four-bar linkage mechanisms 44. The guide rollers 46 are placed on cam surfaces of cam plates 47 provided to the rotation base 31. The cam surfaces have continuously extending inclined guide surfaces 47b that guide such that the guide rollers 46 move obliquely upwards when the widthwise slide base 41 moves.

Rotation of an input shaft is directly transmitted to a front carrier of a planetary gear mechanism, and rotation, which is speed-changed and reversed by a toroidal-type continuously variable speed change unit, is transmitted to a first sun gear. When a Low clutch is applied, rotation of an output carrier of a simple planetary gear unit is transitted to a counter gear mechanism via a common carrier, and then output at an output shaft. When a High clutch H is applied, rotation of a second sun gear is transmitted to the output shaft. Thus, the pinion shaft is shortened and the service life span of a supporting bearing is increased as compared with a planetary gear mechanism that has a three-step pinion.

The invention discloses a wet-strength wastepaper recycling double-pH-value chemical and mechanical pulping method. The method includes a material preparation section, a steaming section, a first extrusion and impregnation chemical and mechanical treatment section, a second extrusion and impregnation chemical and mechanical treatment section, a latency and re-defibering section and a purification, screening and concentration section. Wet-strength wastepaper fiber dissociation re-pulping is achieved while original pulp strength is not reduced through the mechanical strong force effect and the chemical treatment effect. Furthermore, on the two extrusion and impregnation chemical and mechanical treatment sections connected in series, a wet strength agent in wastepaper is oxidized under the acid condition firstly, hydrolysis is further promoted under the alkaline condition, chemical bonding between molecules of the wet strength agent and between the wet strength agent and pulp fibers is more effectively damaged, and the fiber dissociation rate and the re-pulping yield are effectively increased. The problems that the wet-strength wastepaper recycling pulping dissociation rate is low and strength is greatly decreased are solved, and continuous, large-scale, low-water-consumption and low-energy-consumption pollution-free and environment-friendly pulping can be achieved.
