Title: Detecting apparatus for surface flaw
Inventor: KAZAMA AKIRA
IPC: B21C51/00
Filed: 2000-03-13
Granted: 2002-02-18
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting apparatus in which the number of kinds of detectable and judgeable flaws is increased and by which a patternlike surface flaw can be detected by a method wherein the kind or the grade of a flaw is discriminated on the basis of an ellipsoparameter which is calculated by using the photometric value of a pixel corresponding to the same reflecting point on a face to be inspected. SOLUTION: A face to be inspected is irradiated with polarized light, and an elliposparameter (Ψ, Δ) is found by a computing device 33. Since an intensity I, an intensity value Ψ and an intensity value Δ are changed partly, an absolute value is hard to find. Then, the moving average of every parameter is measured by an image processor 35, and a change from a mean value is detected by a feature-extraction kind and grade discrimination and output device 36. In addition, the constant of the moving average is set so as to be matched to the size of a generated flaw. When a change at a set value or higher is detected, the absolute value of an angle is used as an evaluation value regarding a reflection intensity, and a change amount from the mean value is used as an evaluation value regarding the reflection intensity.  The absolute value of the intensity value Δ and that of the intensity Ψas well as the change amount of the reflection intensity I constitute a three-dimensional space. The three-dimensional space (Δ, Ψ, I) is divided into sections on the basis of an empirical method, and the respective sections are applied to the kind and the grade of the flaw.

Abstract: In an infinite speed ratio transmission, a rotation of an input shaft (1) is input both to a continuously variable transmission (2) and a fixed speed ratio transmission (3). A CVT output shaft (4) of the toroidal continuously variable transmission (2) is joined to a sun gear (5A) of a planetary gear set (5), an output shaft (3C) of the fixed speed ratio transmission (3) is joined to a planet carrier (5B) of the planetary gear set (5), and a vehicle is driven under the output of a ring gear (5C) of the planetary gear set (5). A controller of the infinite speed ratio transmission comprises an actuator (30) which varies an amount of torque transmitted between the input shaft (1) and the CVT output shaft (4). A microprocessor (80) controls the actuator (30) so that a torque in the opposite direction to the vehicle travel direction shown by a selection range of a selector lever (86) is not transmitted by the continuously variable transmission (2).  <IMAGE>

Abstract: A method of code phase tracking for CDMA type communication is disclosed together with apparatus including a GPS receiver ( 10 to 15 ) for the same. The method uses a modified early-minus-late correlation function to determine the code phase error between a target pseudorandom noise code of an incoming signal and locally generated replica codes. The early-minus-late correlation function is modified compared to the true function whereby the gradient of the modified function at zero code phase error is increased. This may be achieved my modifying the early-minus-late correlation function after its derivation. Alternatively, it may be modified by modifying variables from which it is derived and in particular, by modifying the either or both of the power spectrums of the subject signal or the early and late replica code signals whereby at least one odd harmonic is reduced in size or removed; at least one even harmonic is increased in size; or the bandwidth is truncating between harmonics so as to excise an adjacent even harmonic.

Abstract: A secondary station has a receiver capable of resolving signals received (504,510) as a plurality of multipath signals from a plurality of base stations during a soft handover process. In order to decode and act upon the received signals in a very short period of time, an initial subset of received multipath signals is processed (506) to provide an estimate of the action needing to be taken by the station, which action is then implemented by the station (508). Later arriving signals are processed separately (512) and used to update the estimate, as a result of which the action already taken may be corrected (514). Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification.
