IPC: B27N3/02
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To give pedestrians a soft and elastic walk feeling with a woody pavement having a natural color tone by mixing granular chips obtained by crushing the core material of a wood and cork grains and evenly laying the mixture to which a resin binder is added on a base layer. SOLUTION: A crushed stone roadbed is formed by laying a crusher run on a levelled ground and pressure-rolling the crusher run. Further, a tack coat is sprinkled over the roadbed and an open grain-size asphalt mixture is formed to form a base layer, which in turn, is used as an application base, and a real woody pavement is applied on the base. In this case, a mixture of cork grains obtained by crushing the core material of a natural wood to the grain diameter and a moisture-curable urethane polymer added is evenly laid on the base layer of every application area. In addition, an acrylic emulsion is applied on the surface to obtain the woody pavement.

Title: Radio communicating system
Inventor: MONMA KOUJI
IPC: H04B1/50
Filed: 1979-06-04
Abstract: PURPOSE:To improve the receiving characteristic, by detecting a modulation signal to reduce the gain of a receiving low-frequency amplifying circuit at a transmission time in the simultaneous radio communication system using an oscillating circuit for transmission and an oscillating circuit for reception. CONSTITUTION:Ocsillating circuit 21 and multiplying circuit 18 are used commonly. The output of circuit 21 is supplied to modulating circuit 15 directly, and the output of circuit 18 is led to the first mixing circuit 5 as a receiving local oscillation signal. Sound switch circuit 22 detects a modulation signal from transmission low- frequency amplifying circuit 17, and the attenuation quantity of circuit 22 is increased by a prescribed quantity to reduce the gain of circuit 17 only when the value of the modulation signal above is a fixed value or more. Though distortion is generated in the demodulation output by interference between the self-transmission signal and the receiving local oscillation signal when modulation is generated for the receiving local oscillation signal by the self-transmission signal, the sound volume from receiver 14 becomes low and is not discordant because the gain of circuit 17 is reduced.

Title: Measuring method by optical fiber
Inventor: TANAKA SHIGERU
IPC: G01M11/02
Filed: 1985-04-03
Abstract: PURPOSE:To attain to enhance the measuring accuracy of transmission characteristics by preventing the formation of modal noise, by cutting the terminal surface of an optical fiber receiving the incidence of the optical signal from a LD light source so as to be made oblique by a specific angle or more to the surface vertical to the axis of the optical fiber or forming the same into a curved surface. CONSTITUTION:In order to substantially reduce the irregularity in a measured value, the incident terminal surface of an optical surface is inclined by 1 deg. or more from the surface vertical to the fiber axis. In order to reduce the effect of the modal noise of reflected light, the incidence terminal surface is formed into a smoothly curved surface shape such as a spherical surface in place of oblique cutting and the same effect can be obtained. It is unnecessary to necessarily apply the above mentioned special cutting or processing of the incidence terminal surface to a fiber itself to be measured and said cutting or processing may be preliminarily applied to an exciting fiber to connect the output terminal of the exciting fiber to a measuring fiber. By this method, the measuring accuracy of the characteristics of the optical fiber is enhanced.

Title: Digital-analog converter
Inventor: HOSOI MASATOSHI
IPC: H03M1/66
Filed: 1982-04-27
Abstract: PURPOSE:To obtain a linear analog signal from a digital signal, by providing a means for changing the ratio of high to low level per one period of the digital signal, a means for integrating the digital signal, and a means for resetting an integration value. CONSTITUTION:When a digital signal inputted to an input terminal A is in a high level, the signal is integrated by a capacitor 14 via a diode 12. When the digital signal is in a low level, since the diode 12 is turned off, the potential of the capacitor 12 is kept as it is. When a reset signal B is inputted to an analog switch 15, the switch 15 is conductive at each occasion, the charge charged in the capacitor 14 is discharged and the potential is brought to zero. The potential inputted to an operational amplifier 13 is equal to the potential charged to the capacitor 14 when the digital signal is in a high level and is proportional to the duty ratio of the digital signal. Thus, the analog output voltage is proportional to the duty ratio.

Abstract: PURPOSE:To reproduce a picture having high quality only with adding a simple process circuit by interpolating a color difference signal when hue fluctuation is occurred in a color difference line sequential color TV system and reducing a coloring with the color difference signal in which two lines are added at recording. CONSTITUTION:A luminance signal Y and an R color difference and a B color difference which are newly processed and lined up are outputted to terminals 103, 104 and 105.
