Title: Carrier phase control loop
Inventor: YOSHIDA ATSUSHI
IPC: H03L7/08
Filed: 1987-11-21
Abstract: PURPOSE:To reduce the disturbance due to noise without making the system band narrow by adding a median filter eliminating noise effectively to a carrier phase control loop. CONSTITUTION:A reception signal expressed by an analysis signal is decided to a desired value by a decider 102. An output of the decider 102 is modified by a conjugation device 13 and a normalizing device 104 and multiplied with the input of the decider 102 by a complex number multiplier 105 and an imaginary part selector 106 extracts only the imaginary part. A T-sec delay device 107 and a median selector 108 constitute a median filter. Then the median selector 108 selects and outputs a median so that the order is just in the middle among N sets of taps of the T-sec delay device 107. Thus, the impulse component is eliminated effectively. After the output of the median selector 108 is smoothed by a low pass filter 109, the phase rotation is given to the input signal by a complex number multiplier 101 by a voltage controlled oscillator 110 and controlled so as to make the carrier phase difference zero.

Title: Liquid jet recording head
Inventor: INAMOTO TADAKI
IPC: B41J2/055
Filed: 1985-12-27
Abstract: PURPOSE:To make the high speed recording possible, by possessing the recording liquid supply channel being interconnected to a recording liquid chamber and having a recording liquid supply port near an orifice. CONSTITUTION:When ink is discharged from a head and a liquid drop is formed, the electric pulse corresponding to a recording signal is applied to a heating element 102 via a conductive material from an outside drive source. Thereby, the heating element 102 is heated, a portion of solvent components in the ink effervesces and the sudden change in volume is caused. Ink liquid is discharged from an orifice 107 and an ink drop is formed. In order to form ink drops continuously, the ink liquid of a discharged content must be supplemented until the subsequent electric pulse is applied to form a meniscus at the top of the orifice. However, this ink liquid is supplemented from the rear of the ink liquid 103 and at the same time, ink is also supplemented through a recording liquid supply channel 110. Therefore, the time required for returning to the ink meniscus can be decreased.

Title: Optical clock signal recovery device
Inventor: ITO FUMIHIKO
IPC: H04B10/299
Filed: 1994-11-29
Abstract: PURPOSE: To extract a high speed optical clock signal directly in synchronism with a bit period in a frequency band (100Gpbs or over) at which an electric circuit cannot trace the frequency. CONSTITUTION: Output lights of two sets of optical signal oscillators 11, 12 are added and outputs an optical signal with a frequency difference, that is, a frequency of a beat signal. A phase difference between the phase of the optical signal and the phase of an optical signal data string is detected. The frequency of a beat signal is adjusted by controlling the oscillated frequency from the two sets of the optical signal oscillators 11, 12 so that the phase difference is minimized. For this purpose, the oscillated frequency of the optical signal oscillators in the two oscillators has only to be controlled. Thus, the optical clock signal recovery device is realized, which is suitable for all optical repeaters relaying an optical signal without conversion into an electric signal.

Filed: 1990-11-02
Abstract: PURPOSE:To obtain the inexpensive system with high reliability without making the circuit complicated by providing the circuit receiving an impulse signal relating to a dial pulse signal according to the analog technology and outputting numeral information to the telephone set. CONSTITUTION:When an input level of an impulse signal generated by dialing from a sender side after line connection and converted via an exchange is adjusted to a prescribed value or below at a level adjustment circuit and the adjusted level is outputted to a filter circuit, the filter circuit 2 eliminates a harmonic component of the impulse signal whose level is adjusted and a periodic signal is outputted to a comparator circuit 3. The comparator circuit 3 compares the periodic signal with a predetermined threshold level and when the periodic signal is larger than the threshold level, a count signal is outputted to a counter circuit 4. The counter circuit 4 counts the count signal and outputs a numeral signal to a numeral conversion output section 5, which converts the numeral signal to a relevant code and outputs the result and also outputs a numeral information detection signal to a count control section 6. Thus, the inexpensive dial telephone set with high reliability is obtained.

Title: Biological filter
Inventor: KIHARA YASUHIKO
IPC: C02F3/06
Filed: 1987-11-25
Abstract: PURPOSE:To discharge only backwashing water and impurities and to easily prevent the outflow of a filter medium by separating a contact tank into plural chambers by a partition wall, providing a biological filter bed in each chamber, connecting a backwashing water inlet pipe to each chamber, and furnishing a backwashing water outlet pipe in the vicinity of the surface layer of the filter bed in each chamber. CONSTITUTION:The contact tank 1 is separated into two chambers A and B by the partition wall 12. When the biological filter bed 3 in the chamber A is washed, the valve 11 of the backwashing water outlet pipe 10 of the chamber A is closed, and the valve 11a of the backwashing water outlet pipe 10a of the chamber B is opened. Under such conditions, backwashing water is introduced from the backwashing water inlet pipe 8 of the chamber A, and the filter bed 3 in the chamber A is washed. When the water level in the chamber A rises along with washing, the backwashing water contg. a part of the circulated filter medium 4 flows into the adjacent chamber B past the partition wall 12. In this case, the relatively heavy filter medium 4 settles in the filter bed 4a of the chamber B, and only backwashing water and the lightweight impurities contained in the backwashing water are discharged from the outlet pipe 10a. The filter bed 3a of the chamber B is washed in the same way.

Filed: 1986-12-11
Abstract: PURPOSE:To extract a large quantity of graphic data with a small quantity of data by extracting densely the points having sudden changes and nondensely other points in terms of a curve formed by plural continuous points. CONSTITUTION:A CPU 100 reads out the graphic data written previously into a floppy disk 104 and obtains a parameter to show the changing degrees of a curve of a pattern. Then the data showing the point of a parameter larger than a set reference parameter is extracted out of the disk 104. Therefore the extracted graphic data consists of only the points having larger changes of the pattern curves than the set reference parameter. Furthermore the CPU 100 changes the reference parameter continuously until all extracted data quantity is approximate to the designated data quantity. thus the graphic data consisting of data of quantity approximately equal to the designated quantity and only points having the large changes of curves can be extracted. Thus the graphic data of the large quantity is extracted with the small quantity of data.
