Title: Driving force control device for four-wheel drive vehicle
Inventor: WAKAMI KENICHI
IPC: B60K17/348
Filed: 1990-08-22
Abstract: PURPOSE:To appropriately control torque distribution ratio according to friction coefficient of road surface and improve running performance by detecting lateral acceleration of a vehicle, judging the detected value as someone of a plurality of detected values, and selecting a mode of torque distribution ratio. CONSTITUTION:A lateral acceleration value judging means 37 of an ECU 36 judges the detected value from a lateral acceleration sensor 31 to be someone of a plurality of detected values, and outputs the judged value to a torque distribution ratio control means 38. At inputting a first detected value for example from the lateral acceleration value judging means 37, the torque distribution ratio control means 38 outputs a N-mode selecting signal to a torque distribution device 10 to distribute larger torque to rear wheels than front wheels. At inputting a second detected value, it outputs a P-mode selecting signal to distribute equal torque to the front wheels and the rear wheels. At inputting a third detected value, it is in a territory unnecessary to control, and one of P, N, S is selected.

IPC: F16K31/04
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a torque motor in which the torque generation angle can be enlarged without increasing the volume of a magnet.

Title: Device and method for manufacturing medium-density fiberboard
Inventor: SAWADA NORITOSHI
IPC: B27N3/04
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To enable a polyurethane adhesive whose pot life is short to be easily used by supplying the components of a two-pack type adhesive separately to a wood fiber. SOLUTION: First, raw material chips, for example, are splitted by a refiner in a high pressure splitting step and wood fibers are dried in a blow line step. In parallel with these steps, the components A, B of an adhesive are alternately supplied in several batches through a process from a blow line to a rapid blender. Consequently, the respective components of the adhesive are mechanically mixed with the wood fibers, in an air current, from the blow line step to the rapid blender step, depending upon an adhesive supply position, and a wood fiberboard is obtained through a heat pressure molding process.  In this case, the wood fibers which are dried and subjected to the adjustment of the moisture content are air-fed to the rapid blender so that the chemical reaction of the adhesive can be easily controlled and the wood fiberboard of high performance and stable quality can be obtained. In addition, the adhesion of the adhesive to the machine interior almost does not occur and thus the wasteful consumption of the adhesive can be reduced.

Title: Sliding member
Inventor: FUTAMURA KENICHIRO
IPC: F16C33/12
Filed: 1988-09-08
Abstract: PURPOSE:To improve seizure resistance by setting one side of paired sliding members down to a powder metallugical product made of quench hardening aluminum alloy powder and the other side to dip boronizing steel, respectively. CONSTITUTION:When dip boronizing steel is slidden in using a quench hardening aluminum material as the opposite material, wear in the opposite material is kept back by a highly hardness surface at the relatively initial stage. However, if this slide motion runs to a long period of time, softening of the aluminum ground and falling of an intermetallic compound grain will happen by degrees. Since a large quantity of intermetallic compounds are contained in quench hardening aluminum alloy powder, there in such a fear that wear might be suddenly advanced by a lot of dropping grains. Under this condition, such possibilities that the steel might be agglutinated to the aluminum ground and it is worn out by the metallic compound grains can prevented or restrained from occurring.
