Title: Driving force distribution control device for four-wheel drive vehicle
Inventor: MURAKAMI TAKESHI
IPC: B60K17/348
Filed: 2002-08-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a driving force distribution control device for a four-wheel drive vehicle for reducing adverse effect of different diameter tires on a drive system.  <P>SOLUTION: When it is determined that differential diameter tires are fitted, the driving force transmission ratio of a driving force transmission device is controlled so that the driving force distribution to the rear wheel (driven wheel) side is smaller than a regular value (regular command torque T = pre-torque T1 + ΔN torque T2). In other words, the drive force corresponding to the pre-torque T1 determined by the throttle opening (the acceleration operation) is not distributed to the rear wheel side. Therefore, different from a case that front wheels are directly coupled with the rear wheels, the difference in the number of rotation between the front and rear wheels attributable to the fitting of the differential diameter tires can be absorbed to some degree by the relative rotation of each clutch disk of an electromagnetic clutch mechanism. As a result, any adverse effect on the drive system by the differential diameter tires can be reduced.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for forming a film by which a wear resistant, hard film is formed, e.g., on the surface part to be required in a die member, and to provide a molding die in which a wear resistant, hard film is formed on the surface part to be required by using the same method.  <P>SOLUTION: The surface of a metal base material is subjected to induction heating by electromagnetic high frequency and high speed flame spraying so as to be linked, and the formation of a film deposited on the surface structure of the metal base material is performed, so that a film formation stock consisting of tungsten carbide as the main agent is thermally sprayed so as to be linked with the high frequency induction heating as for a molding die to form the hard film on the surface part to be required. Thus, the problem that, in the conventional film formation method by high speed flame spraying, the formed film does not have a deposited structure with the die base material but is easy to peel from the base material since the base material itself as the object is not heated but only a film formation stock is heated, and then, spraying is performed can be solved.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To condense a light beam with high light utilization efficiency to information recording surfaces respectively of a plurality of kinds of optical recording media varying in the thicknesses of transparent substrates.  <P>SOLUTION: When an optical disk device is loaded with a DVD of 0.6 mm in thickness t<SB>1</SB>of a DVD substrate 2, the light beam 4 of a wavelength λ<SB>1</SB>=655 nm is used as a luminous flux of a numerical aperture NA=0.63 and is condensed to the information recording surface 2a of the DVD substrate 2. When the optical disk device is loaded with a CD of 1.2 mm in thickness t<SB>2</SB>of a CD substrate 3, the light beam 5 of a wavelength λ<SB>2</SB>=790 nm is used as a luminous flux of a numerical aperture nearly 0.45 and is condensed to the information recording surface 3a of the CD substrate 3. The wavefront aberration by a difference in the thicknesses between the substrates 2 and 3 of the DVD and the CD is generated but is offset by the occurrence of the chromatic aberration by a difference in the wavelengths between the light beams 4 and 5. The light beams can thus be well condensed to the respective information recording surfaces 2a and 3a even if there is a difference in the thicknesses of the transparent substrates.  <P>COPYRIGHT: (C)2003,JPO
