Title: Headlight for vehicle
Inventor: MATSUBARA MASAO
IPC: F21Y101/00
Filed: 2000-01-24
Abstract: PROBLEM TO BE SOLVED: To enhance an appearance of a lighting fixture at non-lighting of the lighting fixture in a headlight for a vehicle comprising a reflector of a synthetic resin having a dummy reflecting surface. SOLUTION: A reflector 20 of FRP material has a main reflecting surface 20a into which light from a light source 18a is incident and a dummy reflecting surface 20b formed extendedly toward both sides of left and right from an end portion of its outer circumference into which the light from the light source 18a is not incident. A border portion B of the main reflecting surface 20a with the dummy reflecting surface 20b is formed into a smooth curved surface 20c. By this, it is difficult to visually discriminate the difference of a surface shape between the main reflecting surface 20a and the dummy reflecting surface 20b by observation from the outside. Then, the curved surface 20c forming the border portion B is a surface shape into which the light from the light source 18a is not incident. Furthermore, by connecting the curved surface 20c with the main reflecting surface 20a through a standing wall 20d extended into a front and a rear directions formed along the outer circumference end portion of the main reflecting surface 20a, it can contrive rigidity of the reflector 20 as well as can easily prevent light from coming into the curved surface 20c.

Title: Rotation control method of permanent magnet synchronous motor
Inventor: TAKEMASA AKIRA
IPC: H02P6/06
Filed: 2000-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a method which ensures continuity of a motor current and can restrain fluctuations in the rotational speed, when a load fluctuates. SOLUTION: This permanent magnet synchronous motor is driven by a three- phase AC power source which is supplied with an inverter and always sends a current. Magnetic flux, where magnetic flux of a permanent magnet of a rotor of the motor is interlinked with a coil of a stator, is obtained. The frequency of the obtained magnetic flux is compared with the frequency of the three-phase AC power source supplied to the motor. According to the compared results, a voltage of the three-phase AC power source supplied with the inverter is increased or decreased, thereby making the number of revolutions of the motor constant, irrespective of change of the load.

Title: Method of estimating bone density
Inventor: ANDRES ROSHOLM
IPC: G01N9/24
Filed: 2000-02-16
Abstract: PROBLEM TO BE SOLVED: To obtain a bone density data without requiring the introduction of a reference wedge and other elements by determining the thickness of a cortical bone from a two-dimensional image data of a bone containing information on at least some cortical bones to obtain the density of the bone. SOLUTION: The volume of a cortex is determined using roentgenography. In the case of a cylindrical bone with the diameter W and with the thickness (t) of the cortex, the volume of the bone per unit area is expressed by π.t (1-t/w) and the thickness (t) of the cortex is calculated from this formula. The thickness (t) of the cortex is multiplied by a constant calibrated with respect to a value of the bone density to which the (t) corresponds among one bone or more to determine the bone density. In other words, the bone density can be determined by multiplication between the bone volume and a constant. When the porosity of the bone is taken into consideration, for example, when there is a need for considering age, the constant is replaced with a constant X (1-porosity measured value). This enables obtaining of a bone density data without introducing any reference wedge.
