Abstract: <P>PROBLEM TO BE SOLVED: To provide a signal of which the lighting can be clearly detected by preventing a reflection by a signal light, since the reflection and a pseudo lighting by the signal light of a traffic signal due to direct sunlight in mornings or evenings cause not only drivers but also pedestrians to falsely recognize and thus increase a possibility of a traffic accident.  <P>SOLUTION: To block the direct sunlight entering the signal light of the traffic signal and thus prevent a reflection, antireflection inclined planes to which nonreflective painting is applied and transmission inclined planes passing the light of the traffic signal are combined in a mountain shape to form an antireflection plate arranged in a row in elongated stripe-like forms parallel to one another. The antireflection plate is attached to the front surface of the signal light to prevent a pseudo lighting. Silver mirror painting is applied to the back surface of the antireflection inclined plane for effective irradiation of the light. The antireflection inclined plane is inclined at nearly an elevation angle of a person looking at the signal so that the non- transmission plane does not interfere with the person confirming the signal. Two kinds of the transmission inclined planes are selectively used according to applications: one is formed with thin oblong transparent semicolumnar surfaces arranged in stripe- like forms to diffuse and irradiate the light and the other is formed with oblong transparent inclined surfaces.  <P>COPYRIGHT: (C)2003,JPO

IPC: H03H21/00
Filed: 2001-04-17
Abstract: An input signal is filtered for creating an output signal using an adaptive filter. An error signal is derived from the output signal. The adaptive filter has coefficient whose value can be modified. A value of a coefficient is modified using a derived updating amount. The updating amount is obtained from the product of a value of the input signal, a value of the polarity of the error signal, and a step gain. The step gain has the form 2K with K being an integer and being dependent on a magnitude of the value of the error signal and on a step gain parameter. The updating amount is dependent on both the magnitude and the polarity of the error signal, therefore allowing a precise update of the coefficient. The specific form of the step gain allows a fast derivation of the product.

Abstract: <P>PROBLEM TO BE SOLVED: To provide an objective lens in which clouding is hardly caused even though an environment is fluctuated.  <P>SOLUTION: The objective lens 11 used in an optical pickup or the like is formed by applying a photocatalystic material 3 showing a hydropholic property by being excited by light whose wavelength is ≤420 nm to the surfaces of lenses 14 and 15. Since the photocatalystic material is excited by the light whose wavelength is ≤420 nm and the hydropholic property of a level in which a contact angle with water is set nearly 0° is obtained, the thin film of the water is formed without forming fine waterdrops even though moisture sticks to the surface, so that the objective lens 11 in which the clouding is hardly caused even though the environment is fluctuated is obtained. Thus, it is effective as a countermeasure for lens clouding in the case that it is difficult to clean with a brush or the like due to a complicated constitution such as having a joined part because the objective lens 11 is constituted of several lenses 14 and 15 so as to specially increase numerical aperture NA or the like.  <P>COPYRIGHT: (C)2003,JPO
