Title: Digital fm demodulator
Inventor: MANNO TOSHIKAZU
IPC: H03D3/00
Filed: 1995-02-13
Abstract: PURPOSE: To eliminate the deterioration in the characteristic by providing a digital filter receiving an FM demodulated wave subjected to A/D conversion and having a required frequency band as a cut-off frequency band based on the FM demodulated wave as an FM demodulation circuit. CONSTITUTION: A received demodulated wave is fed to a BPF 2, in which the wave is band-width-limited, an output of the BPF 2 is fed to an A/D converter circuit 3, in which the signal is converted into a digital signal. The FM modulated wave outputted from the circuit 3 is fed to a digital filter 4 acting like an FM demodulation circuit. An HPF characteristic whose cut-off frequency band is a frequency width increasing and decreasing around a center frequency of the demodulated wave, that is, a frequency band of 2 × (maximum frequency shift + maximum modulation frequency) is set for the filter 4. As a result, a shift of a frequency of the FM modulated wave, that is, the frequency modulation component is converted into a voltage component by passing through the filter 4 and then FM demodulation is conducted.

Title: Remover for volatile substances in high-viscous substance
Inventor: ODA CHIKAO
IPC: B01D1/00
Filed: 1980-04-11
Abstract: PURPOSE: To prevent the deterioration of quality of untreated substances due to stagnation and also the choking of inlet and outlet nozzles by a method in which part of treated substances taken out of a vessel is recycled to untreated substance immediately after being sent into the vessel, and mixed while being heated.  
     CONSTITUTION: Treated substances taken out of an outlet nozzle 5 are divided their destination into two directions at a branching point 8. One is taken out as a product 13 through a valve 11, and the other is passed through a by-pass pipe 9 through a valve 10 and then sent as a refluxing liquid 14 through a refluxing liquid inlet nozzle 7 provided near an inlet nozzle 4 for untreated substance to a remover body 1. As a result, because it follows that the untreated substance deprived of heat by flash evaporation is directly heated, the lowering of the temperature of the untreated substance can be prevented and the rise of its viscosity can be avoided. Thus, troubles such as the lowering of the quality of product due to faulty flow and stagnation can be avoided.

Title: Transmission output control system
Inventor: MINAMIMURA KAZUYOSHI
IPC: H04B3/04
Filed: 1992-03-04
Abstract: PURPOSE:To stably control transmission output with high accuracy in the radio system provided with a transmitter and a receiver. CONSTITUTION:A transmission signal is sent from a transmitter 1 to a receiver 2 through a transmission line. The receiver receives the transmission signal as a reception signal and a demodulator 5 demodulates the reception signal as a demodulation signal. In this case, the demodulator detects an error level included in a demodulation signal and an error signal discriminator 6 generates a control signal used to control a transmission output of the transmitter in response to the error level. Then the transmission controls the transmission output based on the control signal. Since the transmission output is controlled in response to the error level in this way, the transmission output is stably controlled.

Title: Light wave interference measuring device
Inventor: TSUKIHARA KOICHI
IPC: G01B11/00
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To accurately measure, for example, the length, displacement, and density of an object by constituting a double path using an achromatic wavelength plate for changing the polarization orientation of light with a plurality of frequencies by a specific, same angle. SOLUTION: Fresnel roms 30-33 are arranged, as an anachromatic wavelength plate with less wavelength dependency, in the measurement light path and the reference light path of an interference part 101, a flat-panel mirror (traveling mirror) 5 for measurement light and a flat-panel mirror (fixed mirror) 34 for reference light are used as reflection mirrors that are required for measuring the amount of travel of, for example, an X-Y stage, and the measurement light path and the reference light path are configured in a double path. With this configuration, each light can be reflected on the flat-panel mirror 5 for two times, thus doubling a measurement resolution. Also, the light axis of transmission light is shifted in parallel by the Fresnel roms 30-33 but incidence light can be guided to the center of an incidence surface, thus increasing the luminous flux of incidence light.  And further, the angle dependency and wavelength dependency of incidence are small, thus enlarging the tolerance of arrangement and miniaturizing a device.
