Filed: 1991-08-07
Abstract: PURPOSE:To eliminate a reflected noise produce by a signal after passing through a switched capacitor low pass filter and to attain high signal quality in the frequency converter employing an amplitude modulator and the switched capacitor low pass filter. CONSTITUTION:A voice signal and a carrier whose frequency is fCAR are inputted to an amplitude modulator (DBM), in which the carrier is amplitude- modulated. The amplitude modulation wave is inputted to a low pass filter (LPF) 14, in which harmonic components 2fCAR, 3fCAR, 4fCAR,... are eliminated. The amplitude modulation wave whose harmonic components are eliminated is inputted to a switched capacitor low pass filter (SCLPF) 12 and only a required modulation signal is segmented based on a steep filter characteristic. Since the harmonic components being a cause to a reflected noise are not inputted to the SCLPF 12, the reflected noise or beat disturbance due to the clock fSCF of the SCLPF 12 is eliminated.

Title: Display device
Inventor: WATANABE YUKO
IPC: G09F13/04
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To improve the visibility of a display mark without impairing effect of a film by using a material with a shielding ability on a luminescence surface side of the film to cover it in a mesh form. SOLUTION: A film 4 is bonded onto a lens 2 of a rear defogger switch, and on a luminescent side of the film 4, namely, on a side, on which a driver visually check a panel, silver color G is printed in a mesh form, and a display mark 3 is formed by printing black thereon except the display mark 3. Although silver color is used to make the display mark 3 to be colored in a white based color in this case, other colors will do if they are a material having a shielding ability. Moreover, pigments, etc., with fine metal powder are also effective. Therefore, when a light source is off, the silver color part on the film luminescent surface, namely, the display mark form can be recognized from any angles by reflection of an external light such as solar light, etc.  Moreover, when the light source is on, the emitted light transmits a louver film on the film, passing through the transmission part of the mesh form silver printing on the luminescent part to display the mark form.

Title: Web winding method
Inventor: KUROKAWA SHOICHI
IPC: B65H18/26
Filed: 1990-07-26
Abstract: PURPOSE:To prevent meandering and winding shape deficiency by positioning contact parts of a touch roll substantially only at embossing parts on both sides in the lateral direction in winding of a web, particularly a thin film, having embossing parts on both sides in the axial direction. CONSTITUTION:In a touch roll winding method where a touch roll 2 is pressed to a winding core 3 side by a cylinder 4 in a process of winding a film 1 around the winding core 3 while the winding core 3 shaft-supported by shaft bearings 5 is being rotated, the touch roll 2 is pressed to embossing parts E, E of the film 1 via protruded annular parts 2a, 2a on both ends of the roll 2 to conduct winding in order to prevent transferring of an end part caused by a stepped difference of the film 1 in the beginning part of winding and winding slippage. Since the embossing parts E, E are pressed by the touch roll 2 from start to finish of winding, the winding slippage is eliminated even when the winding is conducted with low tensile force. Since the winding is conducted with low tensile force and pressing force is exerted only on the embossing parts E, E, transferring of an end part caused by a stepped difference of the film 1 in the beginning part of winding can be prevented.

An intermedium member 1A whose part equivalent to the external angle part in an angle becomes thicker than other parts is then obtained at this stage. At a 2nd stage, then, an external angle part in almost right angled shape is formed at the external angle part by using the caliber die having a desired angle shape. Consequently an angle steel 1 whose external angle part 101 is almost right-angled can be manufactured with good productivity.
