Patent JP-H10191270-A (JP)
Title: Television receiver
Inventor: NODA TSUTOMU
IPC: H04N5/60
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To reproduce a transmission signal obtained by multiplexing a video signal with a digital signal by reducing hindrance between the signals by providing first and second reproduction systems, permitting the second reproduction system to synchronously detect the transmission signal, to demodulate the digital signal and to reproduce the outputted signal to a signal before a polarity is inverted. SOLUTION: The signal of a sound signal band which is multiplexed and transmitted by BPF 414 and which is digitally encoded is extracted from a signal converted into an intermediate frequency in a frequency conversion circuit 403. The extracted signal is synchronously detected by the carrier reproduced in a carrier reproduction circuit 415 and a signal which is orthogonal and is multiplexed/transmitted is detected/demodulated in a synchronism detection circuit 415. The demodulation signal is processed in a spectrum suppression processing signal reproduction circuit and it is returned to a signal before a spectrum suppression processing is executed. An error occurred in the middle of transmission is detected and corrected in a digital signal processing circuit 418.  The digital signal after correction is returned to an analog signal in DAC 419 and it is outputted from an output terminal 420.

Title: Catch call system
Inventor: SENBOKU HIROFUMI
IPC: H04L12/70
Filed: 1991-02-27
Abstract: PURPOSE:To prevent a delay of emergent or important communication by notifying an incoming call from another subscriber to a subscriber in communication. CONSTITUTION:A packet exchange 10 is provided with a catch call buffer 11 other than that for communication and gives a incoming call notice code and a catch call reception enable/disable code to a non-number frame in the packet transmission reception for the communication. When an incoming call packet to a subscriber during communication is received, the operating state of the catch call buffer 11 is checked and when the subscriber is busy, the non-number information frame including the incoming call notice code is sent to the busy subscriber. The busy subscriber returns the non-number information frame including the catch call reception enable/disable code to the packet exchange 10. When the catch call reception enable/disable code of the returned non-number information frame is receptible, the packet exchange 10 sends the incoming call packet while awaiting the relevant subscriber is in the communication enable state.

Title: Method and apparatus for inspecting flaw of pattern
Inventor: NOGUCHI MINORU
IPC: H01L21/66
Filed: 1987-02-16
Abstract: PURPOSE:To detect a flaw smaller than the resolving power of an optical system without transferring data to a hologram or a filter, by respectively irradiating a specimen to be inspected and a standard specimen with two beams adjusted so as to be different by pi in a phase. CONSTITUTION:A mask 30 becoming a specimen to be inspected and a mask 31 becoming a standard specimen are respectively placed on the specimen-to-be-inspected fixing jig 22 and standard specimen fixing jig 23 on an XYZ table 19. The beam emitted from a coherent beam source 5 is separated into two beams by a half mirror 7 and one of two beams adjusted so as to be different by pi in a phase by a phase plate 9 is allowed to irradiate the mask 30 and the other beam is allowed to irradiate the mask 31. The beams allowed to irradiate two masks 30, 31 are reflected from the masks while possess the data of the patterns on the masks to interfere with each other on a half mirror 24. At this time, since the phase data of the beams diffracted by the patterns of the masks 30, 31 become equal, when one of the phases is delayed by pi, luminous intensity becomes weak by the interference. Contrarily, the beams diffracted from a flaw doe not interfere with each other to be emitted to a detector and, therefore, only the flaw can be detected in a brightly glowing state.

Abstract: PURPOSE: To prevent the flowing-out of slag by giving rotating movement to molten metal in a cylinder at the bottom part of a vessel, measuring the molten metal surface level from the back pressure of inert gas blown from a porous refractory, etc., on the cylindrical wall surface and closing a sliding nozzle. CONSTITUTION: The rotating movement is given to the molten metal in a molten metal surface height measuring instrument 15 arranged at the bottom part of a ladle 7 with an electromagnetic stirring coil 1, and the inert gas 3 is blown from the ladle wall through a porous plug or a nozzle having many fine holes. The gas bubbles 8 are accumulated to near the center with a blowing gas centrifugal separator 2 and after floating up the gas bubbles, new molten metal is changed into the molten metal surface height measuring instrument 15. At this time, the molten metal surface height 10 is judged from the back pressure of the blown inert gas 3 continuously measured with a back pressure measuring instrument 4. When the molten metal surface 13 reaches the ladle bottom 9, the sliding nozzle 5 arranged in a long nozzle 6 is closed to prevent the flowing- out of the slag.  By this method, the clean molten metal can be supplied into the solidifying process.

Title: Magneto-resistance effect type head
Inventor: TAKANO KOJI
IPC: G11B5/39
Filed: 1989-02-15
Abstract: PURPOSE:To obtain the head which does not decrease reproduced output when a track width is narrowed by increasing the specific resistance in a magneto- resistance effect element larger the farther from a sliding surface and setting the taper of current wire only partly near the sliding surface. CONSTITUTION:The specific resistance in the part of the magneto-resistance effect element 1 irradiated with inert gaseous ions, such as Ar ions or metal ions, etc., is increased without changing the magnetic resistance of this part when the above-mentioned element is partly irradiated with the above-mentioned ions. The current density of the detecting current I flowing in the magneto- resistance effect element 1 is increased nearer the sliding surface without changing the electric resistance over the entire part of the magneto-resistance effect element 1 so much by controlling the region to be irradiated with the ions. The flow of the detecting current to the boundary region of the electric resistance effect element 1 of the magneto-resistance effect element 1 and the current wires 2 is possible as well by providing the taper to a part of the current wires 2 and, therefore, the effective track width as the head is narrowed to the spacing between a pair of the current wires.

Abstract: PROBLEM TO BE SOLVED: To prevent dropwise condensation from falling down even when uncured cement moldings placed on receiving plates are piled up in multistages and are placed in an aging warehouse by forming a slope on the back surface of a receiving plate. SOLUTION: A receiving plate 10 for a cement molding is processed into a specified shape by using a square bar and a sheet material consisting of a rigid stainless steel sheet.

IPC: H04J14/02
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To judge the erroneous reception of a light wave terminal by filtering a demultiplexed signal with an optical translator unit(OTU). SOLUTION: A terminal station 50 receives the optical signal of wavelengths λ1 to λn and multiplexes it onto an optical carrier by a multiplexing unit OMU 50-1, and ODU 210 of an optical node 200 receives it through an optical path 60. ODU 210 demultiplexes component optical signals λ1 to λn to output. Wavelengths λn , λn-1 are removed and is sent to a desired terminal through each optical wave terminal. Residual signals λ1 to λm are directly sent to OMU 220, multiplexed with other component optical signal and outputted to a terminal station ODU 75-1. As the result of this, a full identification tone is associated with demultiplexed signals λ1 to λn , thereby the erroneous reception of the signals λ1 to λn is judged though an external customer site 25 receives only one signal λn .
