Title: Ghost removing method using digit cord displayed by canonical sign and its device
Inventor: RI MEIKAN
IPC: H04B3/23
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To cancell ghost with a hardware of a small capacity by detecting a video signal transmission channel characteristic based on a ghost reference signal and using a corresponding canonical signed digit code(CSD) filter coefficient. SOLUTION: A video signal with ghost is given to a synchronization and field identifier separator, where a ghost reference signal period is detected by using a window pulse generator 13 or the like so as to separate a ghost reference signal from the video signal. A count and control signal generator 17 decides a characteristic of a video signal transmission channel based on the ghost reference signal and a filter coefficient of a corresponding CSD coefficient is extracted from a coefficient storage device 20 and fed to a ghost elimination device 15, in which a ghost component in the video signal is cancelled. Thus, ghost in the video signal is cancelled with a hardware of a small capacity.

Title: Superconducting switch
Inventor: FUKUHARA KATSUHIKO
IPC: H01H15/24
Filed: 1992-08-28
Abstract: PURPOSE:To realize almost infinite resistance with a small-sized device, by constituting the contact of an electrode formed of superconductor so as to be mechanically shut and opened. CONSTITUTION:When the title switch is used as a superconducting switch for forming a permanent current circuit, a superconducting electrode 1 for transferring is pushed against the contact of a superconducting electrode 2 for fixing, and a current is made to flow in the superconducting state of zero resistance. When the switch is used as almost infinite resistance, the superconducting electrode 1 for transferring is pulled up and the switch is used in the state that the contact is opened. Since the contact of the electrode is mechanically shut and opened, almost infinite resistace can be obtained with a small-sized device. When super-conducting powder is provided between the contacts, the critical current of the switch is improved, and characteristics are enhanced so that the dimension of a superconducting switch can be made smaller.

Title: Information reproducing device
Inventor: KOBAYASHI TADASHI
IPC: G11B7/00
Filed: 1990-08-31
Abstract: PURPOSE:To accurately reproduce recorded information by receiving a light beam reflected by a recording part position of an information recording medium, outputting an electric signal according to an optical characteristic of the recording part position, sampling this electric signal with a prescribed demodulation clock, detecting a peak value of the sampled electric signal and outputting a regenerative signal. CONSTITUTION:The device possesses a recorded signal processing device 10, processing circuits 14 and 15 and a regenerative signal processing device 40, and the electric signal outputted from an optical characteristic detecting means is sampled with the demodulation clock, and then the peak value of this electric signal is detected, so that a recorded signal is regenerated based on this peak value. In this case, the timing for making a voltage value of the electric signal outputted from the optical characteristic detecting means become a peak value is not dependent upon the waveform of the electric signal (that is, irrespective of the size of a recording mark), and is set to be approximately constant intervals. By this method, reproducing jutters are suppressed to a range which is not detrimental to practical use by detecting the peak value after sampling this electric signal with the demodulation clock.

Abstract: PURPOSE:To perform hot-water filling up to an accurate water level in a short time without stopping hot-water filling by a wrong detected information by a method wherein the water level is not detected by a water level sensor within a specified time period after an on-off valve is closed. CONSTITUTION:In hot-water filling control, when filling of a specified hot water amount Wa is finished by a water flow sensor 24, a hot-water filling valve 18 is closed after an on-off valve 24 is closed if it is opened, and after a specified time t1 passes, the water level is detected by a water level sensor 36 to continue hot-water filling. When the water level reaches the specified level, the hot-water filling valve 18 is closed to finish hot-water filling. As the water level is not detected by a water level sensor 36 until the specified time period t1 passes after the on-off valve 24 is closed, hot-water filling does not stopped by a wrong information that may be issued when water flow stops and the pressure in a circulation pipe 22 becomes unstable, and hot-water filling is finished by a water level information that is issued after a stable condition is established, so that the time period required for completing hot-water filling can be shortened.
