Title: Fm receiver
Inventor: NAITOU MICHINORI
IPC: H03D3/02
Filed: 1980-08-14
Abstract: PURPOSE:To obtain an FM receiver of PLL (phase locked loop) system having a high selection degree of reception and good frequency properties of a reproduced sound, by adding a divider between a phase comparator and an intermediate frequency amplifier of an FM receivr of PLL system and carrying out a phase comparison between the divided intermediate frequency signal and the reference frequency. CONSTITUTION:A mixer 2, an intermediate frequency filter 3, an intermediate frequency amplifier 4 and a phase comparator 6 are connected between an input terminal 1 that supplies an FM high frequency signal f1 which is caught by an antenna and amplified by a high frequency amplifier and a reference frequency oscillator 7 that delivers a reference frequency signal f0. Then the output of the comparator 6 is applied to the mixer 2 in the form of a local oscillation frequency signal f2 via a low pass filter 8, a low frequency amplifier 9 and a voltage control local oscillator 10. In such constitution of an FM receiver, a divider 5 that performs a 1/n division is newly added between the amplifier 4 and the comparator 6 to ensure a sufficient margin of phase. Thus the lowering of the loop response speed can be avoided.

Filed: 1980-08-13
Abstract: PURPOSE:To miniaturize a device on the whole by providing a slit part between a subject and a film, by moving this slit part, and thus by using a linear light source as a copying light source. CONSTITUTION:A light shielding case 41 having a linear slit part 41a on a document is moved at right angles to the slit part 41a by driving a wheel 32. At this time, linear information 1a is lit up by an illumination light source 31 and a real image 3a is formed on a film 4 through a lens 2. According to the movement of the case 41, the film 4 moves, so exposure corresponding to the plane of the document is obtained on the film surface. As the light source, long-sized one corresponding to the width of the slit part 41a is preferably used. Consequently, the part requiring illumination is linear and small in area.

Title: Method for diagnosing optical transmission line
Inventor: MORITA TOYOTAKA
IPC: G01M11/02
Filed: 1995-05-10
Abstract: PURPOSE: To accurately diagnose the light damping amount of an optical cable in a short time by transmitting a plurality of diagnosis signals which can be distinguished from each other and are emitted at different intensities from a transmitting side and identifying what degree of intensity in the signals can be received on the receiving side. CONSTITUTION: Intensity-adjusted diagnosis signals are transmitted to a transmission station 12 from a transmission station 11. When the station 12 receives the diagnosis signals, namely, when a photoelectric conversion section 17 D/A- converts the diagnosis signals, the diagnosing section 13 of the station 12 reads the intensity level of the received diagnosis signals from the signal number information of the diagnosis signals contained in the diagnosis signals. After the section 13 reads the intensity level, a response signal to the station 11 is generated by means of a diagnosed data preparing section 14 and sent to the station 11 after the signal is A/D-converted by means of an electrooptical conversion section 16. The photoelectric conversion section 17 of the station 11 D/A- converts the response signal and inputs the converted signal to the diagnosing section 13.
