IPC: H04B1/707
Filed: 1988-02-19
Abstract: PURPOSE:To simplify a circuit constitution and to widely reduce cost by eliminating the need for a pull-in circuit and a synchronism holding circuit, etc., which are constituted of a clock reproducing circuit, a diffused code generation circuit and a loop and have been an essential constituting condition in an ordinary system. CONSTITUTION:In a modulator 10, a two-phase PSK signal as a primary modulated wave signal modulated by a first carrier wave and an information signal is made to be an input signal and the added signal with a second carrier wave from an input terminal In2 is obtained by an arithmetic circuit 2. A multiplier 4 diffuses the obtained added signal by a diffusing code signal from a diffusing code generation circuit 6 and obtains a spread spectrum signal. In a demodulator 20, the spread spectrum signal is inputted and the diffusing code signal that the first carrier wave and the information signal are multiplied and the diffusing code signal multiplied by the second carrier wave are separated and detected by a comb-line filter 11 and inverse diffusion is performed by multiplying both separated and detected signals by the multiplier 16 and two-phase PSK signal are generated and only one of two two-phase PSK signals is outputted through a BPF 17.

Filed: 1994-02-10
Abstract: PURPOSE:To measure absolute angle position with high precision by comparing reference image data generated by irradiating each predetermined rotational position of a rotary disk with laser beams with an input image signal to measure a rotational angle of the rotary disk. CONSTITUTION:A laser beam from a laser light source 1 is converged into a spot of a predetermined size by a lens 2 and irradiates a disk 3. A reflected beam is detected by a TV camera 4, and a two-dimensional image signal for one round of the annular shade on the disk 3 surface where a two-dimensional image signal is outputted is converted by an A/D conversion circuit 7 and stored into a reference memory 9. Before an angle is measured, a two-dimensional image signal from a camera 4 corresponding to a rotational angle position of the disk 3 is converted by the circuit 7 and inputted into a control circuit 8. The circuit 8 compares an inputted two-dimensional digital signal with a reference image data called from the memory 9 by means of a correlator 10, senses an angle from an address of the memory 9 as obtained from the correlator 10, and displays it on a display device 11.

Title: Radio communication system
Inventor: YOTSUYA AKIO
IPC: H04W4/00
Filed: 1984-02-29
Abstract: PURPOSE:To decrease the call duration time by decreasing a non-supervisory time among control channel supervisory and talking channel search performed alternately by a fixed station during the standby time less than the time of a call signal generated by a mobile station. CONSTITUTION:The fixed station F supervises alternately a control channel C-CH and a talking channel S-CH at the standby, and when the C-CH is not supervised, the S-CH is scanned and an idle CH is stored. When the mobile station M hooks off (17) and transmits (15) a call signal, the fixed station F is received (5), one of idle CHs is selected, the mobile station M responds (4), the channel is switched to the selected idle channel CH, and the mobile staion M is switched to a designated idle CH and enters the talking state. The call signal from the mobile station M is prolonged by one call signal length than the time while the fixed station supervises no C-CH. Thus, the time from calling to the connection is decreased to improve the talking efficiency.

Abstract: PURPOSE:To eliminate leakage current through eliminating lack of oxygen by a method wherein, in the manufacture of an electrode for a semiconductor device, a vanadium layer is provided on a silicon-dioxide film. CONSTITUTION:An SiO2 film 2 is formed on the surface of a semiconductor 1. In the substrate 1 p-type or an n-type regions are formed.

Next, by etching the vanadium layer 4 and the aluminum layer 5, an electrode 6 is obtained. Therefore by eliminating lack of oxygen, generation of positive electron is suppressed, and increase of leakage current is prevented.

Abstract: PROBLEM TO BE SOLVED: To securely perform the feeding, separation and carrying of paper sheet with the simple structure, and to reduce a load at the time of carrying so as to enable the smooth carrying. SOLUTION: A paper sheet P of the highest position of a paper platform 11 and a paper separating member 26 and a driven roller 27 are made to pressure-contact with the outside surface of a paper feeding roller 25. Consequently, the paper feeding roller 25 is rotated so as to draw the paper sheet P set on the paper sheet platform 11, and the drawn paper sheet P is carried to a desirable position by the paper feeding roller 25 and the driven roller 27. With this structure, the paper feeding roller 25 can be utilized as a roller of a carrying system, and the number of part items can be thereby reduced. Since the driven roller 27 for carrying the paper sheet P with the paper feeding roller 25 is driven by the rotation of the paper feeding roller 25, a special driving means for rotating the carrying roller 27 is eliminated.  Furthermore, the paper feeding roller 25, the carrying roller 27 and the paper separating member 26 and a connecting member thereof can be unified so as to form a unit.
